1 00:00:00,440 --> 00:00:03,840 Speaker 1: This episode is brought to you by Allogen, a company 2 00:00:03,880 --> 00:00:08,360 Speaker 1: redefining how we fight cancer and autoimmune disease. By pushing 3 00:00:08,400 --> 00:00:12,559 Speaker 1: the boundaries of cartes cell therapy. Allogen is creating next 4 00:00:12,600 --> 00:00:16,560 Speaker 1: generation off the shelf treatments designed to reach more people. 5 00:00:17,200 --> 00:00:26,040 Speaker 1: Learn more at allogen dot com. Hi everyone. Cancer treatment 6 00:00:26,040 --> 00:00:28,440 Speaker 1: has come such a long way from the blunt tools 7 00:00:28,440 --> 00:00:33,199 Speaker 1: of chemo to today's precision immunotherapies like cart or chimeric 8 00:00:33,320 --> 00:00:38,159 Speaker 1: antigen receptor T cell therapy. Our partner, Allogen Therapeutics, is 9 00:00:38,200 --> 00:00:43,199 Speaker 1: helping lead that transformation. Cart is amazing. It reprograms your 10 00:00:43,200 --> 00:00:47,479 Speaker 1: own immune cells to find and destroy cancer, and because 11 00:00:47,479 --> 00:00:50,280 Speaker 1: it's targeted, it does it without some of the most 12 00:00:50,280 --> 00:00:54,360 Speaker 1: brutal side effects of say, chemotherapy. But access has been 13 00:00:54,400 --> 00:00:58,200 Speaker 1: a real challenge. That's where Allergen comes in developing truly 14 00:00:58,640 --> 00:01:03,040 Speaker 1: off the shelf CARTI treatments made from healthy donor cells 15 00:01:03,080 --> 00:01:06,760 Speaker 1: and ready when patients need them most. Who better to 16 00:01:06,840 --> 00:01:11,600 Speaker 1: understand these exciting developments and Alergen's chief medical Officer, Doctor 17 00:01:11,720 --> 00:01:15,680 Speaker 1: Zach Roberts. We talked about how cancer outsmart some of 18 00:01:15,720 --> 00:01:20,160 Speaker 1: its fiercest opponents, but how CARTE therapy is changing the 19 00:01:20,200 --> 00:01:23,240 Speaker 1: face of the disease, but first I wanted to know 20 00:01:23,280 --> 00:01:26,200 Speaker 1: what drew him to cancer research in the first place. 21 00:01:28,880 --> 00:01:32,200 Speaker 1: Doctor Zachary Roberts. So nice to meet you. I admire 22 00:01:32,280 --> 00:01:36,880 Speaker 1: people like you so much who are cancer scientists who 23 00:01:36,880 --> 00:01:40,040 Speaker 1: are trying to come up with better treatments to save 24 00:01:40,160 --> 00:01:44,880 Speaker 1: people's lives or to at least manage their disease. I'm 25 00:01:44,959 --> 00:01:47,960 Speaker 1: curious how did you get interested in cancer research? And 26 00:01:48,000 --> 00:01:50,400 Speaker 1: by the way, thank you that I appreciate that you 27 00:01:50,440 --> 00:01:51,480 Speaker 1: did well. 28 00:01:51,760 --> 00:01:53,920 Speaker 2: Thanks Katie. This is absolutely lovely to be here with 29 00:01:53,960 --> 00:01:57,400 Speaker 2: you today. I have to say that I was interested 30 00:01:57,400 --> 00:02:01,720 Speaker 2: from a very very young age. I grew up wanting 31 00:02:01,720 --> 00:02:04,600 Speaker 2: to be a scientist, wanting to be a doctor. I 32 00:02:04,680 --> 00:02:08,880 Speaker 2: became quite fascinated with how cells kind of went wrong. 33 00:02:09,680 --> 00:02:11,200 Speaker 2: There are a normal cell one day and then there 34 00:02:11,200 --> 00:02:15,040 Speaker 2: are cancer cell the next, and so really understanding what 35 00:02:15,120 --> 00:02:17,600 Speaker 2: genes were in play, what went wrong, what switches got 36 00:02:17,639 --> 00:02:20,680 Speaker 2: turned on, which ones got turned off, all of that 37 00:02:20,840 --> 00:02:23,240 Speaker 2: was so fascinating to me as a youngster. 38 00:02:23,440 --> 00:02:25,560 Speaker 1: How old were you when you became interested in that? 39 00:02:25,760 --> 00:02:29,400 Speaker 2: Oh it's probably seven eight really? Yeah? 40 00:02:29,400 --> 00:02:29,800 Speaker 1: Wow? 41 00:02:29,919 --> 00:02:32,880 Speaker 2: Yeah. But what I was really interested in was how 42 00:02:32,919 --> 00:02:35,080 Speaker 2: the immune system interacts with cancer. 43 00:02:35,440 --> 00:02:39,320 Speaker 1: Immunotherapy used to be kind of mocked in the medical establishment, right, 44 00:02:39,639 --> 00:02:43,840 Speaker 1: and now it seems to hold the key to dealing 45 00:02:43,880 --> 00:02:46,720 Speaker 1: with a lot of cancers. But I want to go back, 46 00:02:46,760 --> 00:02:49,720 Speaker 1: if I could for a minute, to talk about how 47 00:02:49,760 --> 00:02:54,519 Speaker 1: cancer treatment has changed and how immunotherapy has been embraced. 48 00:02:55,120 --> 00:03:00,160 Speaker 1: My husband was diagnosed with stage four colon cancer in 49 00:03:00,240 --> 00:03:04,080 Speaker 1: nineteen ninety seven. He was just forty one years old, 50 00:03:04,840 --> 00:03:07,720 Speaker 1: and of course, back then, may I call you Zach, 51 00:03:07,919 --> 00:03:10,680 Speaker 1: of course I did a lot of research. I was 52 00:03:10,800 --> 00:03:13,960 Speaker 1: just desperate to figure out if there was any way 53 00:03:14,680 --> 00:03:19,440 Speaker 1: we could treat and save my husband's life. And back 54 00:03:19,480 --> 00:03:25,480 Speaker 1: then these approaches were just starting to gain a little speed. 55 00:03:25,680 --> 00:03:29,720 Speaker 1: But for the most part, everything was treated with chemotherapy. 56 00:03:31,000 --> 00:03:37,960 Speaker 1: Chemotherapy obviously was a great development in cancer treatment, but 57 00:03:38,720 --> 00:03:41,440 Speaker 1: there are a lot of things wrong with chemo. Can 58 00:03:41,520 --> 00:03:44,480 Speaker 1: you talk about that and talk about how you've seen 59 00:03:45,000 --> 00:03:47,960 Speaker 1: cancer therapies evolve in the year since. 60 00:03:48,240 --> 00:03:52,400 Speaker 2: Absolutely, so, You're right, chemotherapy is very much a double 61 00:03:52,480 --> 00:03:54,560 Speaker 2: edged sword. And if you go back a leave it 62 00:03:54,680 --> 00:03:57,720 Speaker 2: even a little further than your husband's diagnosis, maybe another 63 00:03:57,760 --> 00:04:03,400 Speaker 2: fifty years. Let's say cancer was uniformally fatal at that time, 64 00:04:03,480 --> 00:04:06,520 Speaker 2: and no matter what cancer you had, it was just 65 00:04:06,560 --> 00:04:10,120 Speaker 2: a matter of time before you would succumb. In the 66 00:04:10,160 --> 00:04:14,000 Speaker 2: middle of the twentieth century was when through serendipitous and 67 00:04:14,120 --> 00:04:19,320 Speaker 2: lots of hard work, we discovered that these class of 68 00:04:19,360 --> 00:04:23,160 Speaker 2: medicines chemotherapy could kill very rapidly dividing cells. 69 00:04:23,760 --> 00:04:26,279 Speaker 1: And we should just mention the double edged sword of 70 00:04:26,320 --> 00:04:29,080 Speaker 1: it is that it kills a lot of healthy cells too. 71 00:04:29,320 --> 00:04:33,440 Speaker 1: It's indiscriminate. I used to call it the scorch body therapy, 72 00:04:33,760 --> 00:04:37,960 Speaker 1: right because it just kills everything, and that while the 73 00:04:38,040 --> 00:04:42,719 Speaker 1: healthy cells grow back, it's pretty ravaging. 74 00:04:42,480 --> 00:04:46,360 Speaker 2: Yes body. I mean, the way that chemotherapy works is 75 00:04:46,400 --> 00:04:49,960 Speaker 2: it has a slightly more toxic effect on cells that 76 00:04:50,000 --> 00:04:54,000 Speaker 2: are rapidly dividing. So in your body, you've got cells 77 00:04:54,040 --> 00:04:56,400 Speaker 2: that are very very slowly dividing maybe once a year, 78 00:04:57,400 --> 00:04:59,400 Speaker 2: and then you've got cells that are dividing every day. 79 00:05:00,000 --> 00:05:02,440 Speaker 2: You've got cancer cells that are dividing multiple times per day. 80 00:05:02,480 --> 00:05:04,839 Speaker 2: So what we try to do with chemotherapy is just 81 00:05:04,960 --> 00:05:07,080 Speaker 2: tune it so we get the cells that are dividing 82 00:05:07,120 --> 00:05:11,320 Speaker 2: the most rapidly. But your hair cells, the lining of 83 00:05:11,320 --> 00:05:14,919 Speaker 2: your stomach, and your GI tract, those are all rapidly 84 00:05:14,960 --> 00:05:19,760 Speaker 2: dividing cells. So absolutely super super toxic, But the targeted 85 00:05:19,800 --> 00:05:23,039 Speaker 2: therapies were not. They were very well tolerated by and 86 00:05:23,120 --> 00:05:26,600 Speaker 2: large and these patients could go back to their normal lives. 87 00:05:26,640 --> 00:05:28,800 Speaker 2: And this is coming back to the first question you 88 00:05:28,839 --> 00:05:33,160 Speaker 2: asked me, the biology of cancer. In the intrinsic biology 89 00:05:33,160 --> 00:05:36,320 Speaker 2: of a cell, we know that there are certain genes 90 00:05:36,400 --> 00:05:39,360 Speaker 2: that in some cancers are activated in a way that 91 00:05:40,080 --> 00:05:44,240 Speaker 2: gives rise to the cancer in that cell. That the 92 00:05:44,279 --> 00:05:46,680 Speaker 2: ability it gives the ability of that cell to become tumorous. 93 00:05:47,240 --> 00:05:49,680 Speaker 2: And if we could design a drug that targets that 94 00:05:49,800 --> 00:05:53,520 Speaker 2: specific gene, we can arrest the cancer. 95 00:05:53,760 --> 00:05:57,640 Speaker 1: It's so amazing to me how challenging cancer is as 96 00:05:57,680 --> 00:06:00,080 Speaker 1: a disease. I used to you know, I think a 97 00:06:00,120 --> 00:06:03,479 Speaker 1: lot of people think of cancer one disease, but it's 98 00:06:03,720 --> 00:06:09,120 Speaker 1: thousands of diseases in thousands of different biologies. In other words, 99 00:06:09,320 --> 00:06:12,720 Speaker 1: I got cancer, Zach. Even if it's the same kind 100 00:06:12,760 --> 00:06:15,400 Speaker 1: of cancer. If we both got a certain cancer, the 101 00:06:15,440 --> 00:06:17,920 Speaker 1: way my body reacts to it and the way your 102 00:06:17,960 --> 00:06:20,479 Speaker 1: body reacts to it could be totally different. 103 00:06:20,600 --> 00:06:24,000 Speaker 2: Right, Absolutely, that's a most people, You're absolute right, do 104 00:06:24,040 --> 00:06:26,240 Speaker 2: not they think of cancer as a monolithic disease. But 105 00:06:26,279 --> 00:06:29,280 Speaker 2: you're right, it's thousands of diseases. I mean, there are 106 00:06:29,360 --> 00:06:30,600 Speaker 2: hundreds of phlymphomas. 107 00:06:30,760 --> 00:06:35,640 Speaker 1: So when you think of targeted therapies, is immunotherapy a 108 00:06:35,720 --> 00:06:37,640 Speaker 1: subset of targeted therapy. 109 00:06:38,440 --> 00:06:41,440 Speaker 2: So I would say, no, it's different ball of whax. 110 00:06:41,520 --> 00:06:43,359 Speaker 2: That's a different ball of wax. So in my mind, 111 00:06:43,480 --> 00:06:45,240 Speaker 2: I kind of the way I organize it, there's sort 112 00:06:45,279 --> 00:06:49,320 Speaker 2: of three pillars of cancer care. There's pillar one, which 113 00:06:49,360 --> 00:06:52,159 Speaker 2: is chemo, which still has a big role to play, yes, 114 00:06:52,279 --> 00:06:53,120 Speaker 2: you know, for better or worse. 115 00:06:53,200 --> 00:06:55,600 Speaker 1: And by the way, I don't mean to dump all 116 00:06:55,640 --> 00:06:57,640 Speaker 1: over chemo because it's so lightly. 117 00:06:57,400 --> 00:06:58,440 Speaker 2: You're not gonna hurt my feelings. 118 00:06:58,480 --> 00:06:59,920 Speaker 1: No, but you know what I mean. And I think 119 00:07:00,040 --> 00:07:02,839 Speaker 1: a lot of people benefit so much from chemo therapy. 120 00:07:03,240 --> 00:07:07,000 Speaker 2: It absolutely can prolong people's lives. And and one thing 121 00:07:07,000 --> 00:07:11,040 Speaker 2: that has really improved in the last twenty years is 122 00:07:11,320 --> 00:07:13,000 Speaker 2: the supportive care element of this. 123 00:07:13,080 --> 00:07:14,720 Speaker 1: So you have fewer side effects. 124 00:07:14,320 --> 00:07:17,000 Speaker 2: Fewer side effects, so you know, we've got growth factors 125 00:07:17,040 --> 00:07:21,640 Speaker 2: to manage low blood counts, so you feel stronger between cycles. 126 00:07:21,720 --> 00:07:26,640 Speaker 2: We've got very powerful anti nausea medicines now so and 127 00:07:26,960 --> 00:07:30,240 Speaker 2: in a way interestingly that's actually made chemo even a 128 00:07:30,240 --> 00:07:32,280 Speaker 2: little more effective because it means we can push the 129 00:07:32,320 --> 00:07:35,040 Speaker 2: dose a little bit higher and the patients are able 130 00:07:35,120 --> 00:07:39,480 Speaker 2: to to manage it. So, yes, chemo still it gets 131 00:07:39,480 --> 00:07:41,840 Speaker 2: a bad rap, but it still has a pretty big 132 00:07:41,920 --> 00:07:44,960 Speaker 2: role to play. So that's pillar one. Pillar two, I 133 00:07:45,000 --> 00:07:49,720 Speaker 2: think is this targeted therapy, which is looking for specific 134 00:07:50,640 --> 00:07:55,440 Speaker 2: regulators of cancer and targeting those directly. And then pillar 135 00:07:55,520 --> 00:07:58,840 Speaker 2: three I would put as the imminotherapy in of things, 136 00:07:58,880 --> 00:08:05,480 Speaker 2: and that targets a pathway in T cells, which are 137 00:08:05,520 --> 00:08:07,960 Speaker 2: really kind of the field generals of the immune system. 138 00:08:08,760 --> 00:08:12,040 Speaker 2: It targets what is often called the immunological break of 139 00:08:12,080 --> 00:08:12,720 Speaker 2: those cells. 140 00:08:13,080 --> 00:08:17,320 Speaker 1: Let's go back and talk about T cells because they 141 00:08:17,400 --> 00:08:22,120 Speaker 1: sort of are, as you mentioned, the warriors of immunotherapy, right, 142 00:08:22,440 --> 00:08:26,080 Speaker 1: Are there other cells other than T cells that can 143 00:08:26,680 --> 00:08:28,520 Speaker 1: act like warriors against cancer. 144 00:08:28,760 --> 00:08:32,880 Speaker 2: Absolutely so, even though it's a little cliched, I think 145 00:08:33,240 --> 00:08:39,840 Speaker 2: kind of the army sort of analogy really works for 146 00:08:39,880 --> 00:08:43,079 Speaker 2: the immune system because you actually have many different kinds 147 00:08:43,080 --> 00:08:47,560 Speaker 2: of cells. Each of them has one or several very 148 00:08:47,600 --> 00:08:51,440 Speaker 2: important roles to play. There's a lot of cooperation, there's 149 00:08:51,480 --> 00:08:53,920 Speaker 2: a lot of crosstalk between the cells. So the cells 150 00:08:53,920 --> 00:08:56,240 Speaker 2: will actually talk to each other, obviously not with voices, yeah, 151 00:08:56,280 --> 00:08:59,480 Speaker 2: but with molecules that they secrete, and a T cell 152 00:08:59,480 --> 00:09:03,040 Speaker 2: will secrete molecule that a B cell will take in, 153 00:09:03,520 --> 00:09:06,960 Speaker 2: and that B cell, with that message will act now differently, 154 00:09:07,040 --> 00:09:09,360 Speaker 2: it'll take a sort of an order from the T cell. 155 00:09:09,760 --> 00:09:11,800 Speaker 1: Is the T cell the general I like to. 156 00:09:11,720 --> 00:09:14,040 Speaker 2: Think of them as the general Now I call them 157 00:09:14,080 --> 00:09:16,320 Speaker 2: field generals, though, which is the term I may have 158 00:09:16,400 --> 00:09:19,400 Speaker 2: made up, but it means that they actually are doing 159 00:09:19,400 --> 00:09:21,120 Speaker 2: some of the work themselves. They're not sort of sitting 160 00:09:21,120 --> 00:09:23,280 Speaker 2: in a back office somewhere. They're actually on the front 161 00:09:23,320 --> 00:09:26,839 Speaker 2: lines because they have Without getting too far into the 162 00:09:26,840 --> 00:09:28,920 Speaker 2: weeds here, as I said, I'm an aemynologist, which is 163 00:09:28,960 --> 00:09:29,720 Speaker 2: really my passion. 164 00:09:29,800 --> 00:09:31,760 Speaker 1: Well, I'm really into this, so go ahead. 165 00:09:32,760 --> 00:09:36,360 Speaker 2: The T cells have, in addition to their ability to 166 00:09:36,400 --> 00:09:39,720 Speaker 2: send messages to many different other cell types B cells, macrophages, 167 00:09:40,280 --> 00:09:44,679 Speaker 2: dendritic cells, they also have a very specific molecule on 168 00:09:44,720 --> 00:09:47,520 Speaker 2: their surface called the T cell receptor, and the T 169 00:09:47,640 --> 00:09:51,120 Speaker 2: cell receptor is unique to that T cell. So let's 170 00:09:51,120 --> 00:09:53,160 Speaker 2: say you've got a billion T cells, and more likely 171 00:09:53,200 --> 00:09:56,040 Speaker 2: you've got one hundred billion T cells in your body 172 00:09:56,120 --> 00:09:59,240 Speaker 2: each one has its own unique T cell receptor, and 173 00:10:00,000 --> 00:10:03,320 Speaker 2: bodies have evolved in that way so that you can 174 00:10:03,360 --> 00:10:06,199 Speaker 2: in any infection that you encounter. Right when you're born. 175 00:10:06,640 --> 00:10:08,680 Speaker 2: It's not like you're just given a set of instructions 176 00:10:08,679 --> 00:10:10,920 Speaker 2: of all the infections that you could ever see or 177 00:10:10,960 --> 00:10:15,600 Speaker 2: all the allergens. Right you are born with a truly 178 00:10:15,720 --> 00:10:17,800 Speaker 2: naive immune system, and so you have to have this 179 00:10:17,880 --> 00:10:21,400 Speaker 2: ability to create diversity in your in your T cell 180 00:10:21,640 --> 00:10:24,120 Speaker 2: population so that you can attack anything that comes in. 181 00:10:24,520 --> 00:10:28,240 Speaker 2: So the T cell receptors have an ability to recognize infections, 182 00:10:28,240 --> 00:10:31,840 Speaker 2: and some of them have an ability to recognize tumors. 183 00:10:31,720 --> 00:10:33,680 Speaker 1: As a T sell in a car T sell the 184 00:10:33,720 --> 00:10:34,240 Speaker 1: same thing. 185 00:10:34,559 --> 00:10:39,200 Speaker 2: Great question, so and great transition. So as as our 186 00:10:39,440 --> 00:10:43,080 Speaker 2: ability to understand the function of T cells grew over 187 00:10:43,120 --> 00:10:46,679 Speaker 2: the nineteen eighties, the nineteen nineties, and then into the 188 00:10:46,679 --> 00:10:49,160 Speaker 2: two thousands. And it's really rather recent that we started 189 00:10:49,200 --> 00:10:52,600 Speaker 2: to really tease all this apart. Many Nobel prizes were 190 00:10:52,600 --> 00:10:57,760 Speaker 2: involved in this whole story in the early nineties. Someone, well, 191 00:10:57,880 --> 00:10:59,880 Speaker 2: let me fill in one other little gap here, So 192 00:11:00,440 --> 00:11:03,280 Speaker 2: I mentioned B cells as another member of this little army. 193 00:11:04,280 --> 00:11:07,640 Speaker 2: B cells are famous because, like T cells, they've each 194 00:11:07,679 --> 00:11:11,199 Speaker 2: got their own specificity. Right, there's billions upon billions of 195 00:11:11,240 --> 00:11:14,479 Speaker 2: B cells, and each one has its own special specificity 196 00:11:14,480 --> 00:11:17,640 Speaker 2: that is unique to whatever infection that you may get 197 00:11:17,720 --> 00:11:22,760 Speaker 2: or may never get. When that little molecule that's on 198 00:11:22,800 --> 00:11:24,840 Speaker 2: the surface of the B cells gets cut off and 199 00:11:24,920 --> 00:11:27,680 Speaker 2: floats around your body by itself, we call it an antibody. 200 00:11:28,200 --> 00:11:30,640 Speaker 2: So B cells make the antibodies. 201 00:11:30,880 --> 00:11:31,720 Speaker 1: We love B cells. 202 00:11:31,760 --> 00:11:33,840 Speaker 2: We love B cells. We love antibodies. They're good for 203 00:11:33,880 --> 00:11:36,480 Speaker 2: a lot of things. They're a huge part of the 204 00:11:36,520 --> 00:11:42,240 Speaker 2: immune response. And we've known how antibodies work for a 205 00:11:42,280 --> 00:11:45,160 Speaker 2: little longer than we've known how T cell receptors work. 206 00:11:45,920 --> 00:11:50,920 Speaker 2: And so One Suite began to realize the potency of 207 00:11:50,960 --> 00:11:53,680 Speaker 2: T cells and their ability to kill target cells, including 208 00:11:53,840 --> 00:11:55,719 Speaker 2: cancer sometimes. And we can do this in the lab. 209 00:11:55,720 --> 00:11:57,440 Speaker 2: We can get them to kill cancer cells in the lab, 210 00:11:57,880 --> 00:11:59,480 Speaker 2: but we couldn't really figure out how to do it 211 00:11:59,480 --> 00:12:02,400 Speaker 2: in people until we started to use the checkpoint blockers 212 00:12:02,440 --> 00:12:03,360 Speaker 2: in twenty eleven. 213 00:12:03,440 --> 00:12:10,079 Speaker 1: And the checkpoint blockers basically they basically allow the T 214 00:12:10,320 --> 00:12:16,000 Speaker 1: cells to kill the cancer cells without being told to 215 00:12:16,120 --> 00:12:19,400 Speaker 1: back off. They're like, screw you, cancer, We're coming in. 216 00:12:19,679 --> 00:12:21,520 Speaker 1: There's nothing you can do to stop us. 217 00:12:21,600 --> 00:12:24,520 Speaker 2: That's right, it's taking the break off. The checkpoint is 218 00:12:24,559 --> 00:12:27,480 Speaker 2: another term for the break. So if you block the checkpoint, 219 00:12:28,000 --> 00:12:31,280 Speaker 2: the immune checkpoint, the T cells will just go on 220 00:12:31,360 --> 00:12:39,319 Speaker 2: and kill. So in the early nineties, an Israeli scientist 221 00:12:39,440 --> 00:12:43,760 Speaker 2: named Zella Geshar got this idea that if he took 222 00:12:43,800 --> 00:12:47,319 Speaker 2: an antibody and actually stuck it onto a T cell, 223 00:12:47,840 --> 00:12:50,640 Speaker 2: an antibody of known specificity, so we know what this 224 00:12:50,679 --> 00:12:53,520 Speaker 2: antibody is targeting, and we actually put it into a 225 00:12:53,559 --> 00:12:53,960 Speaker 2: T cell. 226 00:12:54,000 --> 00:12:57,240 Speaker 1: Give me an example of an antibody like a specific one. 227 00:12:58,200 --> 00:13:02,280 Speaker 2: So remember what the first one he actually did. But 228 00:13:02,440 --> 00:13:06,560 Speaker 2: let's say let's say her too. I'm going to make 229 00:13:06,559 --> 00:13:08,200 Speaker 2: this up, right, this is making up. Her two is 230 00:13:08,200 --> 00:13:14,720 Speaker 2: a famous breast cancer marker. It's the drug trans twos 231 00:13:14,760 --> 00:13:18,520 Speaker 2: amab her septin. Her targets her two. So her two 232 00:13:18,600 --> 00:13:20,319 Speaker 2: is on the surface of breast cancer. So let's say 233 00:13:20,320 --> 00:13:22,960 Speaker 2: we had an antibody to her too, and there are many, 234 00:13:23,559 --> 00:13:24,559 Speaker 2: herceptin is one of them. 235 00:13:25,000 --> 00:13:26,080 Speaker 1: Thank you, Denny Slayman. 236 00:13:26,360 --> 00:13:29,559 Speaker 2: Yes, absolutely, Danny Slayman. So let's say let's say I 237 00:13:29,559 --> 00:13:31,400 Speaker 2: wanted to make a car te cell with her sceptin. 238 00:13:31,480 --> 00:13:33,839 Speaker 2: So this going back to the early nineties. Let's say 239 00:13:33,840 --> 00:13:35,920 Speaker 2: I have got this antibody that is un that is 240 00:13:36,040 --> 00:13:40,520 Speaker 2: targets the HER two antibody hertoo molecule, and I put 241 00:13:40,520 --> 00:13:42,520 Speaker 2: that into a T cell. And I do that by 242 00:13:43,200 --> 00:13:47,720 Speaker 2: actually creating the genetic sequence that is used to make 243 00:13:47,760 --> 00:13:50,679 Speaker 2: the antibody. Because everything comes from DNA, so the DNA 244 00:13:50,760 --> 00:13:52,920 Speaker 2: is like the blueprint. So you take that piece of DNA, 245 00:13:53,280 --> 00:13:55,480 Speaker 2: you stick it into the T cell. So the T 246 00:13:55,640 --> 00:13:58,079 Speaker 2: cell's none the wiser and it sees this piece of 247 00:13:58,160 --> 00:14:00,200 Speaker 2: DNA and it says, oh, I need to take an 248 00:14:00,200 --> 00:14:02,360 Speaker 2: antibody now. So the antibody goes to the surface of 249 00:14:02,360 --> 00:14:02,920 Speaker 2: the T cell. 250 00:14:03,040 --> 00:14:04,840 Speaker 1: It doesn't reject it. It says welcome. 251 00:14:05,080 --> 00:14:09,320 Speaker 2: It says welcome. It's just DNA. And so they are. 252 00:14:10,000 --> 00:14:12,720 Speaker 2: They are appliable in a way. We can modify them 253 00:14:12,840 --> 00:14:15,040 Speaker 2: using genetic techniques. 254 00:14:15,000 --> 00:14:18,640 Speaker 1: Which brings us to allogenic therapy because I'm like, how 255 00:14:18,679 --> 00:14:19,280 Speaker 1: do you do that? 256 00:14:19,520 --> 00:14:23,080 Speaker 2: So the basic biology is you have to modify the 257 00:14:23,120 --> 00:14:25,880 Speaker 2: T cell, right, because as I said, right, you've got 258 00:14:25,920 --> 00:14:27,840 Speaker 2: billions of T cells, they are all unique. Right, that's 259 00:14:27,880 --> 00:14:29,600 Speaker 2: not going to help you if you need to kill 260 00:14:30,240 --> 00:14:32,800 Speaker 2: a kilogram of tumor, right, you need a lot of 261 00:14:32,840 --> 00:14:35,080 Speaker 2: T cells that are all focused on the same thing. 262 00:14:36,560 --> 00:14:39,200 Speaker 2: The easiest way to do that is to modify the 263 00:14:39,240 --> 00:14:41,640 Speaker 2: T cells. Now it's not easy, it's hard to do that, 264 00:14:41,880 --> 00:14:44,760 Speaker 2: but if you can do it successfully and get them 265 00:14:44,760 --> 00:14:47,000 Speaker 2: all to see the same thing and react in the 266 00:14:47,040 --> 00:14:50,040 Speaker 2: same way, suddenly you've got an entire army that you 267 00:14:50,080 --> 00:14:55,440 Speaker 2: can deploy to eradicate this tumor. So the CAR T 268 00:14:55,600 --> 00:14:58,960 Speaker 2: cells are just that. So we take in the early days, 269 00:14:58,960 --> 00:15:00,680 Speaker 2: it was an antibody put in the T cell, and 270 00:15:00,680 --> 00:15:03,240 Speaker 2: suddenly the T cell became specific for her too. In 271 00:15:03,320 --> 00:15:08,240 Speaker 2: our example, which was itself a massive breakthrough. It took 272 00:15:08,320 --> 00:15:12,200 Speaker 2: another twenty years. We talked about Carl June before we 273 00:15:12,240 --> 00:15:14,600 Speaker 2: get started, and he was one of the pioneers in this. 274 00:15:15,760 --> 00:15:18,480 Speaker 2: It really we really had to incorporate a lot of 275 00:15:18,520 --> 00:15:21,320 Speaker 2: what we had learned about how T cells themselves work 276 00:15:21,440 --> 00:15:24,920 Speaker 2: before we do anything to them to then design a 277 00:15:25,040 --> 00:15:30,520 Speaker 2: perfect CAR. And CAR stands for chimerican, chimeric anigen receptor 278 00:15:31,760 --> 00:15:35,560 Speaker 2: chimeric because it's part T cell receptor, part antibody, so 279 00:15:35,600 --> 00:15:40,120 Speaker 2: it's a chimera and it's an anigen, which anigen is 280 00:15:40,120 --> 00:15:44,560 Speaker 2: a fancy word for the molecule that this receptor sees. 281 00:15:44,920 --> 00:15:47,600 Speaker 2: So the anogen is on the tumor cell and the 282 00:15:47,640 --> 00:15:52,440 Speaker 2: receptor sees theanogen, so chimeric anigen receptor. And so once 283 00:15:52,520 --> 00:15:56,080 Speaker 2: we designed an effective CAR we put that into T 284 00:15:56,200 --> 00:15:59,080 Speaker 2: cells using the same general techniques we can talk about that. 285 00:15:59,120 --> 00:16:01,960 Speaker 2: It's actually quite interesting. We use modified HIV virus to 286 00:16:02,000 --> 00:16:06,520 Speaker 2: do that, and we drop this DNA into the T cells. 287 00:16:06,520 --> 00:16:09,240 Speaker 2: The T cells again are none the wiser, and suddenly 288 00:16:09,280 --> 00:16:11,760 Speaker 2: you now you've got a population of T cells with 289 00:16:12,160 --> 00:16:15,800 Speaker 2: uniform specificity. They all see the same thing in this case, 290 00:16:15,960 --> 00:16:18,560 Speaker 2: her too in our example. So if you've got a 291 00:16:18,600 --> 00:16:21,080 Speaker 2: patient and there's no CART cells, effective cart cells for 292 00:16:21,120 --> 00:16:24,440 Speaker 2: her too. But we'll come back to you know, the 293 00:16:24,480 --> 00:16:27,200 Speaker 2: real situation in a moment when when the analogy is done. 294 00:16:27,640 --> 00:16:30,720 Speaker 2: If you've got a breast cancer patient who's got a 295 00:16:31,000 --> 00:16:34,880 Speaker 2: very her too positive tumor, and many do, and you 296 00:16:34,960 --> 00:16:37,880 Speaker 2: put the car T cells in them into the patients, 297 00:16:38,240 --> 00:16:40,680 Speaker 2: suddenly you've got billions of car T cells that are 298 00:16:40,720 --> 00:16:43,760 Speaker 2: all finding her too on the on the breast cancer 299 00:16:43,760 --> 00:16:46,720 Speaker 2: cells and they'll kill the breast cancer cells. So it's 300 00:16:46,840 --> 00:16:51,000 Speaker 2: remarkable how well this works in solid tumors. It's been 301 00:16:51,040 --> 00:16:54,240 Speaker 2: a little tricky. Allergen actually has has some great data 302 00:16:54,240 --> 00:16:58,760 Speaker 2: in solid tumors, but it works really well in blood cancers. 303 00:16:58,800 --> 00:17:01,120 Speaker 2: Lymphoma's leukemia is multiple myeloma. 304 00:17:01,520 --> 00:17:04,199 Speaker 1: Why you know, I always have a hard time, just 305 00:17:04,240 --> 00:17:07,879 Speaker 1: because my experience with my husband was calling cancer. My 306 00:17:07,960 --> 00:17:12,200 Speaker 1: sister pancreatic I was diagnosed with early stage breast cancer 307 00:17:12,200 --> 00:17:15,679 Speaker 1: three years ago. I always have a hard time envisioning 308 00:17:16,040 --> 00:17:19,760 Speaker 1: how cancer acts in the blood. Can you explain that. 309 00:17:19,680 --> 00:17:21,199 Speaker 2: To me, picularly blood cancer. 310 00:17:21,440 --> 00:17:25,320 Speaker 1: Yeah, Like, well, my mom had lymphoma, yes, so that 311 00:17:25,520 --> 00:17:30,359 Speaker 1: was a blood cancer, right, yes, But how I have 312 00:17:30,400 --> 00:17:33,720 Speaker 1: a hard time envisioning in the blood stream how blood 313 00:17:33,720 --> 00:17:36,399 Speaker 1: cancers were. Can you explain that to me? 314 00:17:36,600 --> 00:17:41,080 Speaker 2: Sure? So it's probably helpful to go back and realize 315 00:17:41,119 --> 00:17:46,000 Speaker 2: that all cancers start with one cell more or less, 316 00:17:46,600 --> 00:17:49,280 Speaker 2: and we give the name to the cancer depending on 317 00:17:49,320 --> 00:17:53,480 Speaker 2: which cell became the cancer. So in pancreatic cancer, it 318 00:17:53,480 --> 00:17:58,280 Speaker 2: was a pancreas cell. In blood cancers, it's often cells 319 00:17:58,320 --> 00:18:06,080 Speaker 2: of the immune system. So T cells, B cells both 320 00:18:06,160 --> 00:18:07,840 Speaker 2: can can give rise to cancer. 321 00:18:08,800 --> 00:18:11,040 Speaker 1: Wait a second, I thought they were fighting cancer. 322 00:18:11,119 --> 00:18:13,920 Speaker 2: They are, they are, but they are they are subject 323 00:18:13,960 --> 00:18:18,840 Speaker 2: to the same molecular malfunctions as any other cell in 324 00:18:18,880 --> 00:18:25,479 Speaker 2: your body, So lymphoma, non Hoskins lymphoma, almost all of 325 00:18:25,520 --> 00:18:28,640 Speaker 2: those are come from B cells. So your mom had 326 00:18:28,800 --> 00:18:32,639 Speaker 2: mantle cell. Correct, mantle cell comes from a from a 327 00:18:32,640 --> 00:18:39,199 Speaker 2: B cell. Most leukemias that are that are lymphoid in 328 00:18:39,280 --> 00:18:41,280 Speaker 2: nature come from B cells. There are some T cell 329 00:18:41,359 --> 00:18:45,280 Speaker 2: leukemias as well. Most leukemias that we think of actually 330 00:18:45,320 --> 00:18:48,400 Speaker 2: come from a different blood cell that are give rise 331 00:18:48,440 --> 00:18:52,440 Speaker 2: to macrophages and other immune cells. But they all they're 332 00:18:52,480 --> 00:18:56,359 Speaker 2: all start in the marrow or in the lymph nodes. 333 00:18:56,680 --> 00:18:59,840 Speaker 2: So you've got thousands of lymph nodes in your body. 334 00:19:00,440 --> 00:19:03,920 Speaker 2: This is where all of the immune system cells all 335 00:19:03,920 --> 00:19:08,040 Speaker 2: come to congregate and form an immune response to an infection. 336 00:19:08,240 --> 00:19:09,680 Speaker 2: So if you get a cut in your arm, you 337 00:19:09,720 --> 00:19:12,080 Speaker 2: get some bacteria. You've got a lot of lymph nodes 338 00:19:12,119 --> 00:19:14,680 Speaker 2: in your arm, and as the bacteria make their way 339 00:19:14,720 --> 00:19:16,800 Speaker 2: into your body, they find their way into the lymph 340 00:19:16,840 --> 00:19:19,520 Speaker 2: nodes and that's where the TMB cells encounter them and. 341 00:19:19,440 --> 00:19:20,240 Speaker 1: They eat it up. 342 00:19:20,280 --> 00:19:22,600 Speaker 2: They eat it, they kill it, they tell their friends 343 00:19:22,600 --> 00:19:24,879 Speaker 2: about it. The friends then get deployed and go and 344 00:19:25,119 --> 00:19:29,359 Speaker 2: get inflammation in the cut. So often B in T 345 00:19:29,520 --> 00:19:32,240 Speaker 2: cell lymphomas will start in a lymph node because there's 346 00:19:32,280 --> 00:19:37,800 Speaker 2: such an explosive proliferation of those cells in response to 347 00:19:37,840 --> 00:19:40,040 Speaker 2: an infection. But this is where those T cells and 348 00:19:40,040 --> 00:19:42,760 Speaker 2: B cell lives. So if you have lymphoma, it's not 349 00:19:42,840 --> 00:19:46,080 Speaker 2: so much circulating in the blood as it is in 350 00:19:46,119 --> 00:19:49,119 Speaker 2: the lymph nodes. And so you'll see patients come in 351 00:19:49,160 --> 00:19:53,320 Speaker 2: with very just enlarged lymph nodes throughout their body. You 352 00:19:53,400 --> 00:19:55,200 Speaker 2: do a PET scan and you'll see lymph nodes even 353 00:19:55,200 --> 00:19:58,960 Speaker 2: in their abdomen and their chest. So throughout leukemias, on 354 00:19:59,000 --> 00:20:03,000 Speaker 2: the other hand, they are often circulating. Mantle cell lymphoma 355 00:20:03,040 --> 00:20:06,960 Speaker 2: is an example that is a also has a circulating phase. 356 00:20:07,320 --> 00:20:09,720 Speaker 2: So you can actually draw blood in these leukemia patients 357 00:20:09,760 --> 00:20:11,520 Speaker 2: and find tumor cells in the blood. 358 00:20:11,640 --> 00:20:13,600 Speaker 1: But what you're saying is the T cells in the 359 00:20:13,640 --> 00:20:17,639 Speaker 1: B cells are basically not doing their jobs in the 360 00:20:17,680 --> 00:20:22,200 Speaker 1: blood cancer and that's what's creating the opportunity for blood cancer. 361 00:20:22,600 --> 00:20:25,560 Speaker 2: Or it just takes one. So you might have you 362 00:20:25,640 --> 00:20:28,240 Speaker 2: might have ninety nine point nine to nine percent of 363 00:20:28,280 --> 00:20:30,199 Speaker 2: your B cells might be doing the right thing, and 364 00:20:30,240 --> 00:20:32,680 Speaker 2: your T cells might be doing the right thing. You've 365 00:20:32,720 --> 00:20:34,320 Speaker 2: just got one bad apple in there. 366 00:20:40,800 --> 00:20:44,200 Speaker 1: This episode is brought to you by Allogen, a company 367 00:20:44,240 --> 00:20:48,679 Speaker 1: redefining how we fight cancer and autoimmune disease. By pushing 368 00:20:48,760 --> 00:20:52,280 Speaker 1: the boundaries of car T cell therapy. Allogen is creating 369 00:20:52,640 --> 00:20:56,919 Speaker 1: next generation off the shelf treatments designed to reach more people. 370 00:20:57,560 --> 00:21:10,360 Speaker 1: Learn more at allogen dot com. So clearly, an approach 371 00:21:10,920 --> 00:21:16,359 Speaker 1: to killing cancer is to make these T cells or 372 00:21:16,400 --> 00:21:19,880 Speaker 1: turn them into car T sells, right, which give them 373 00:21:19,920 --> 00:21:25,040 Speaker 1: the ability to attack specific cancer cells. Right, How do 374 00:21:25,080 --> 00:21:25,480 Speaker 1: you do that? 375 00:21:26,200 --> 00:21:30,080 Speaker 2: So the approved therapies that are on the market already 376 00:21:30,119 --> 00:21:35,960 Speaker 2: for blood cancers all start with the patient's T cells themselves, 377 00:21:37,680 --> 00:21:42,280 Speaker 2: and so the procedure works as follows. You. The patient 378 00:21:42,320 --> 00:21:46,240 Speaker 2: who's got the lymphoma goes and sits down for several 379 00:21:46,240 --> 00:21:49,880 Speaker 2: hours in as procedure called aphoresis, and that is it's 380 00:21:49,960 --> 00:21:52,720 Speaker 2: kind of like an enhanced blood donation where we where 381 00:21:52,760 --> 00:21:56,320 Speaker 2: we take out billions and billions and billions of circulating 382 00:21:56,359 --> 00:21:59,720 Speaker 2: normal T cells from that patient. That becomes the manufacturing 383 00:21:59,760 --> 00:22:02,560 Speaker 2: star material. We take that bag of T cells and 384 00:22:02,600 --> 00:22:05,159 Speaker 2: that's a literal bag of T cells, and then we 385 00:22:05,400 --> 00:22:07,520 Speaker 2: bring it to the lab and that's when we do 386 00:22:07,600 --> 00:22:12,679 Speaker 2: our genetic modification. We use that that that special HIV 387 00:22:13,000 --> 00:22:16,600 Speaker 2: virus to deliver this genetic material into the T cells. 388 00:22:17,320 --> 00:22:20,600 Speaker 2: The T cells then become car T cells. We wash 389 00:22:20,680 --> 00:22:22,840 Speaker 2: them and purify them and put them in a different bag, 390 00:22:23,280 --> 00:22:26,320 Speaker 2: and then they get frozen and sent back to the 391 00:22:26,320 --> 00:22:29,600 Speaker 2: hospital where the patient is receiving their care, their thought 392 00:22:29,640 --> 00:22:31,879 Speaker 2: at the bedside, and they're infused into the patient. 393 00:22:31,960 --> 00:22:32,760 Speaker 1: It is amazing. 394 00:22:32,840 --> 00:22:35,159 Speaker 2: It's amazing. It's amazing that it works as well as 395 00:22:35,160 --> 00:22:35,560 Speaker 2: it does. 396 00:22:35,760 --> 00:22:39,120 Speaker 1: So what happens when they get an infusion of their 397 00:22:39,160 --> 00:22:43,119 Speaker 1: modified car T cells, right, or their T cells that 398 00:22:43,160 --> 00:22:45,320 Speaker 1: are modified and turned into car T cells. 399 00:22:45,359 --> 00:22:50,080 Speaker 2: Yeah, okay, we often just saying it, you're nailing it. 400 00:22:50,720 --> 00:22:52,639 Speaker 2: We we often just say car T cells. They get 401 00:22:52,680 --> 00:22:57,359 Speaker 2: their cart cell infusion. So so the infusion itself, and 402 00:22:57,400 --> 00:23:00,960 Speaker 2: I've seen many is sort of little anti climactic. It 403 00:23:01,000 --> 00:23:04,200 Speaker 2: takes about five minutes. Cells just go into a normal 404 00:23:04,240 --> 00:23:09,679 Speaker 2: IV and then what happens next can be exciting. The 405 00:23:09,720 --> 00:23:13,679 Speaker 2: patients can get quite sick with the side effects of 406 00:23:13,680 --> 00:23:16,480 Speaker 2: these cart cells because, as you'd imagine, they're on overdrive. 407 00:23:16,600 --> 00:23:20,000 Speaker 2: They're on overdrive, and they all have the same specificity, 408 00:23:20,640 --> 00:23:23,120 Speaker 2: so they're all seeing the same thing at the same 409 00:23:23,160 --> 00:23:25,600 Speaker 2: exact time, within minutes of being infused, and. 410 00:23:25,600 --> 00:23:27,760 Speaker 1: It's like swarming. This the swarming, right. 411 00:23:27,680 --> 00:23:30,840 Speaker 2: And they're also dividing, so they can actually divide in 412 00:23:30,960 --> 00:23:36,479 Speaker 2: the body ten thousandfold, and so you get this massive 413 00:23:36,520 --> 00:23:39,000 Speaker 2: immune response. You feel like you have the flu. Sometimes 414 00:23:39,080 --> 00:23:42,600 Speaker 2: that can become quite serious. We learned in the early 415 00:23:42,680 --> 00:23:46,280 Speaker 2: days how to manage this pretty effectively. But once you 416 00:23:46,320 --> 00:23:48,840 Speaker 2: get through that first week or two where the toxicities 417 00:23:48,880 --> 00:23:52,919 Speaker 2: can be the side effects can be a little you know, difficult. 418 00:23:53,440 --> 00:23:56,880 Speaker 2: Once you get through that, then you begin to see 419 00:23:56,880 --> 00:23:58,760 Speaker 2: the effects of these cart cells on the tumor. And 420 00:23:58,800 --> 00:24:03,440 Speaker 2: these patients will come in often one month after their infusion, 421 00:24:03,840 --> 00:24:07,160 Speaker 2: before their infusion, you know, they're just loaded with cancer 422 00:24:07,400 --> 00:24:10,359 Speaker 2: on a scan, and they come in one month later 423 00:24:10,920 --> 00:24:14,920 Speaker 2: in a complete remission. Every visible tumor is gone. 424 00:24:15,400 --> 00:24:17,359 Speaker 1: So I was just going to ask you what is 425 00:24:17,400 --> 00:24:21,840 Speaker 1: the success rate for this kind of therapy and specifically 426 00:24:21,840 --> 00:24:22,840 Speaker 1: in blood cancers. 427 00:24:22,960 --> 00:24:25,879 Speaker 2: Yeah, so in blood cancers it works really, really well 428 00:24:26,720 --> 00:24:28,800 Speaker 2: in the best cases. You know, there's a lot of 429 00:24:28,840 --> 00:24:31,439 Speaker 2: different trials out there, but you can see remissions like 430 00:24:31,480 --> 00:24:35,320 Speaker 2: this eighty ninety plus percent of the time, depending on 431 00:24:35,640 --> 00:24:40,280 Speaker 2: the patient. The disease and the car T cell that 432 00:24:40,359 --> 00:24:45,520 Speaker 2: you're using that applies to leukemia, lymphoma, and myeloma. Myeloma 433 00:24:45,600 --> 00:24:49,199 Speaker 2: is a very common blood cancer, famously and curable, and 434 00:24:49,440 --> 00:24:52,640 Speaker 2: just earlier this year we saw data that was five 435 00:24:52,720 --> 00:24:56,080 Speaker 2: years out from the first trial using a Carte cell 436 00:24:56,200 --> 00:25:04,679 Speaker 2: for mioloma, patient's still incomplete re mission. So really astonishing efficacy. 437 00:25:05,119 --> 00:25:08,560 Speaker 2: Not only high response rates but durable. These patients can 438 00:25:08,840 --> 00:25:11,040 Speaker 2: and they're leading normal lives after a single infusion. 439 00:25:11,440 --> 00:25:17,240 Speaker 1: And what about recurrence? Is it just too early to say. 440 00:25:17,640 --> 00:25:21,000 Speaker 2: So with blood cancers, they tend to come back quickly, 441 00:25:21,080 --> 00:25:23,720 Speaker 2: usually within most most of the time within one year. 442 00:25:24,520 --> 00:25:27,920 Speaker 2: But certainly if you're beyond two years out, you generally 443 00:25:27,960 --> 00:25:29,680 Speaker 2: are in a good place. So there may be a 444 00:25:29,720 --> 00:25:34,520 Speaker 2: few relapses after two years. So if you can, you know, 445 00:25:34,560 --> 00:25:36,679 Speaker 2: certainly for leukemium film, if you're two years out with 446 00:25:36,720 --> 00:25:39,919 Speaker 2: no recurrence, you know, as on Collegist Animals has to 447 00:25:39,840 --> 00:25:42,720 Speaker 2: say it, but you're probably cured at that point. 448 00:25:43,280 --> 00:25:47,480 Speaker 1: The problem with this, I mean, it's extraordinary and so exciting, 449 00:25:48,119 --> 00:25:54,800 Speaker 1: but the process itself is is is a lot, right, 450 00:25:54,960 --> 00:25:58,760 Speaker 1: That's a lot. And I know that access has been 451 00:25:58,800 --> 00:26:01,640 Speaker 1: a problem talk about out the people who can benefit 452 00:26:01,680 --> 00:26:05,560 Speaker 1: from this and the people who aren't able to access 453 00:26:05,600 --> 00:26:08,359 Speaker 1: this kind of therapy, which is always so upsetting to me. 454 00:26:09,200 --> 00:26:14,280 Speaker 2: That's an absolutely topical question, Katie, because ten years ago, 455 00:26:14,359 --> 00:26:16,439 Speaker 2: when I was doing all of this work with the 456 00:26:16,520 --> 00:26:19,360 Speaker 2: Carte cells and we were seeing these remissions, you know, 457 00:26:19,800 --> 00:26:23,720 Speaker 2: as I just described, it was a revolution. We had 458 00:26:23,760 --> 00:26:25,960 Speaker 2: never seen anything like this before, and it was so 459 00:26:26,119 --> 00:26:28,919 Speaker 2: exciting to be doing this every single day. But what 460 00:26:29,040 --> 00:26:33,080 Speaker 2: became very clear is that it was very very few 461 00:26:33,119 --> 00:26:37,480 Speaker 2: patients who are actually able to receive this procedure. 462 00:26:37,640 --> 00:26:39,080 Speaker 1: Why because of expense. 463 00:26:39,760 --> 00:26:43,439 Speaker 2: Sometimes it's expensed. Sometimes it this whole thing with the 464 00:26:43,440 --> 00:26:46,440 Speaker 2: blood collection and the manufacturing that can take a month 465 00:26:46,520 --> 00:26:49,720 Speaker 2: or even two months, sometimes even longer. And so if 466 00:26:49,760 --> 00:26:52,679 Speaker 2: you are a patient as often as the case, who's 467 00:26:52,720 --> 00:26:56,240 Speaker 2: had a disease relapse, their cancer has come back, it 468 00:26:56,320 --> 00:26:59,600 Speaker 2: is an emergency and it is sometimes you know, galloping 469 00:26:59,640 --> 00:27:02,320 Speaker 2: along and growing very fast, and you become frankly too 470 00:27:02,400 --> 00:27:04,960 Speaker 2: sick to even receive the car T cells if they 471 00:27:05,040 --> 00:27:10,720 Speaker 2: come back. So and this bespoke manufacturing, one patient, one 472 00:27:10,760 --> 00:27:15,400 Speaker 2: manufacturing process, one product, really has been a deep limitation 473 00:27:15,840 --> 00:27:19,760 Speaker 2: to getting access. And it's only done in certain certain centers, 474 00:27:19,960 --> 00:27:24,840 Speaker 2: large academic centers predominantly, So I knew from the from 475 00:27:25,000 --> 00:27:28,320 Speaker 2: very early that we would need a new plan. And 476 00:27:28,400 --> 00:27:30,840 Speaker 2: so you know, we've talked a little bit about this 477 00:27:30,920 --> 00:27:36,000 Speaker 2: termalogenetic Allogenetic car T cell therapies are really a path 478 00:27:36,080 --> 00:27:40,040 Speaker 2: to solving this access problem. And it sounds like a 479 00:27:40,040 --> 00:27:42,840 Speaker 2: subtle difference between the regular car T cells, which are 480 00:27:42,880 --> 00:27:45,959 Speaker 2: sometimes called autologous car T cells made from the same person, 481 00:27:46,560 --> 00:27:50,439 Speaker 2: but it's actually quite different. It's we take the cells 482 00:27:50,440 --> 00:27:53,080 Speaker 2: from a healthy donor, so the T cells don't come 483 00:27:53,080 --> 00:27:56,560 Speaker 2: from the patient, they come from a healthy person, and 484 00:27:56,600 --> 00:27:58,760 Speaker 2: we take those T cells and we make them into 485 00:27:58,800 --> 00:28:02,080 Speaker 2: car T cells, and then we of that product to 486 00:28:02,160 --> 00:28:06,080 Speaker 2: a patient. Right now, even ten plus years after the 487 00:28:06,280 --> 00:28:08,400 Speaker 2: very first or close to ten years from the very 488 00:28:08,400 --> 00:28:12,520 Speaker 2: first approvals of CARTI, only twenty percent of patients who 489 00:28:12,560 --> 00:28:16,400 Speaker 2: are eligible are actually able to access this therapy. It's 490 00:28:16,800 --> 00:28:20,560 Speaker 2: a lengthy process, it's complex, there's insurance issues, it's only 491 00:28:20,600 --> 00:28:23,560 Speaker 2: given in certain centers. The majority of patients in our 492 00:28:23,600 --> 00:28:26,760 Speaker 2: country don't get their care at those centers. So there 493 00:28:26,840 --> 00:28:31,000 Speaker 2: is just multiple burials barriers that prevent a patient who 494 00:28:31,040 --> 00:28:34,240 Speaker 2: could have their life saved and their cancer cured by 495 00:28:34,240 --> 00:28:36,639 Speaker 2: car T cells, they just can't get them, which is 496 00:28:36,680 --> 00:28:42,800 Speaker 2: a tragic situation. So after we figured out how to 497 00:28:42,840 --> 00:28:45,160 Speaker 2: make car T cells in the very beginning, and we 498 00:28:45,160 --> 00:28:48,680 Speaker 2: were doing it using patients material patients T cells and 499 00:28:48,720 --> 00:28:50,920 Speaker 2: making the car T cells in the lab. During in 500 00:28:50,920 --> 00:28:55,360 Speaker 2: that process, I described one of the companies that was 501 00:28:55,400 --> 00:28:57,720 Speaker 2: at the forefront of that was a company called Kite Pharma. 502 00:28:57,720 --> 00:29:00,000 Speaker 2: It was a company that was founded by Ari Beldergrim 503 00:29:00,160 --> 00:29:03,440 Speaker 2: and David Chang, both of whom at the end of 504 00:29:03,480 --> 00:29:06,480 Speaker 2: the Kite cycle went on to form Allogen. And the 505 00:29:06,520 --> 00:29:11,120 Speaker 2: reason that Allergen came about was because even though we 506 00:29:11,120 --> 00:29:15,680 Speaker 2: were working with these carte cells at Kite, and all 507 00:29:15,720 --> 00:29:19,040 Speaker 2: three of us were working on this together, we very 508 00:29:19,120 --> 00:29:22,080 Speaker 2: quickly realized that there was going to be significant limitations 509 00:29:22,080 --> 00:29:26,760 Speaker 2: in our ability to scale this manufacturing process, and with 510 00:29:26,840 --> 00:29:29,440 Speaker 2: our inability to scale, we were going to run into 511 00:29:29,560 --> 00:29:34,000 Speaker 2: massive access problems. There just wasn't going to be the 512 00:29:34,040 --> 00:29:38,600 Speaker 2: wherewithal of the ability the manpower that would be required 513 00:29:38,640 --> 00:29:41,640 Speaker 2: to make products for all these patients that needed to 514 00:29:41,720 --> 00:29:45,240 Speaker 2: receive them. So the vision at the time was, how 515 00:29:45,280 --> 00:29:49,840 Speaker 2: can we take healthy donors and collect their T cells 516 00:29:49,880 --> 00:29:52,400 Speaker 2: and then make dozens or hundreds of doses from a 517 00:29:52,440 --> 00:29:55,840 Speaker 2: single manufacturing run instead of making one dose from a 518 00:29:55,880 --> 00:29:59,960 Speaker 2: manufacturing run. And so that was really how allogen was 519 00:30:00,120 --> 00:30:04,000 Speaker 2: born and the new field of allogenetic car T cells 520 00:30:04,240 --> 00:30:04,760 Speaker 2: was launched. 521 00:30:04,960 --> 00:30:09,120 Speaker 1: Wait a seconds, so all car T cells Zacher created 522 00:30:09,200 --> 00:30:13,520 Speaker 1: equal Like, if you needed car T therapy, I could 523 00:30:13,520 --> 00:30:18,720 Speaker 1: donate my T cells that would become car T cells 524 00:30:18,920 --> 00:30:20,880 Speaker 1: that could be used in your body. It's not like 525 00:30:20,920 --> 00:30:22,360 Speaker 1: a bone marrow donation. 526 00:30:22,680 --> 00:30:25,000 Speaker 2: It is not like a bone marrow donator. Actually crazy, Yeah, 527 00:30:25,040 --> 00:30:28,440 Speaker 2: And actually the question is a very interesting one, and 528 00:30:28,600 --> 00:30:32,120 Speaker 2: it's partly why it's been so difficult to achieve this, 529 00:30:32,640 --> 00:30:36,400 Speaker 2: to use a healthy, a healthy donor starting material to 530 00:30:36,440 --> 00:30:40,200 Speaker 2: make these cart cells. The immunology is a challenge. Our 531 00:30:40,240 --> 00:30:45,320 Speaker 2: bodies are able to recognize other people's immune systems as foreign, 532 00:30:46,160 --> 00:30:49,840 Speaker 2: and those immune systems are able to recognize our body 533 00:30:49,880 --> 00:30:54,120 Speaker 2: as foreign. Because we can use elegant gene editing technologies, 534 00:30:54,360 --> 00:30:57,640 Speaker 2: we can actually solve that immunology. And so we can 535 00:30:57,800 --> 00:31:02,080 Speaker 2: use universal donors. We can take a donor to use 536 00:31:02,120 --> 00:31:05,680 Speaker 2: your example, Yes, your cells could work for my cancer. 537 00:31:05,720 --> 00:31:08,200 Speaker 2: It's not actually how it works. We have there's a 538 00:31:08,280 --> 00:31:10,320 Speaker 2: sort of an elaborate testing and we have to make 539 00:31:10,320 --> 00:31:11,640 Speaker 2: sure that we're picking the dright donors. 540 00:31:11,680 --> 00:31:13,640 Speaker 1: And it's there and I might be too old. 541 00:31:14,760 --> 00:31:16,320 Speaker 2: There is an age limit. I don't know if it 542 00:31:16,320 --> 00:31:18,160 Speaker 2: would apply to you or not, but yes, those sorts 543 00:31:18,200 --> 00:31:21,280 Speaker 2: of attributes are are minded and therefore we can make 544 00:31:21,880 --> 00:31:25,160 Speaker 2: from a single donation. We can make up to one 545 00:31:25,160 --> 00:31:27,760 Speaker 2: thousand doses of Carte cells from a single donation. 546 00:31:28,360 --> 00:31:29,959 Speaker 1: Are we talking about a thousand patients? 547 00:31:30,000 --> 00:31:32,640 Speaker 2: A thousand patients? Wow? Yeah, the donation piece is not 548 00:31:32,760 --> 00:31:35,040 Speaker 2: the limitter for us because we can make so many 549 00:31:35,560 --> 00:31:40,040 Speaker 2: doses from a single donation. We have many many doses 550 00:31:40,440 --> 00:31:44,560 Speaker 2: frozen away. What I think the barrier that we need 551 00:31:44,600 --> 00:31:47,320 Speaker 2: to solve is we need to find better ways to 552 00:31:47,360 --> 00:31:51,320 Speaker 2: administer these products at the place where patients get their care. 553 00:31:51,600 --> 00:31:55,080 Speaker 1: Instead of just a few or academic centers all across 554 00:31:55,120 --> 00:31:57,680 Speaker 1: the country. They have to be in rural hospitals and 555 00:31:58,120 --> 00:32:01,200 Speaker 1: places low income areas, right. 556 00:32:01,000 --> 00:32:04,680 Speaker 2: I mean even yes, absolutely, but even large suburban areas. 557 00:32:04,680 --> 00:32:08,160 Speaker 2: I mean, you would be surprised at how reluctant patients 558 00:32:08,240 --> 00:32:13,440 Speaker 2: are to leave their primary oncologists to get a referral into, 559 00:32:13,680 --> 00:32:16,760 Speaker 2: you know, across town to you know, the gigantic building 560 00:32:16,880 --> 00:32:19,560 Speaker 2: and the nurses who name I don't know, right. 561 00:32:19,680 --> 00:32:23,880 Speaker 1: Can't the Cartie cells be shipped to various places. 562 00:32:23,600 --> 00:32:27,800 Speaker 2: In the context of the autologous, the the yes, kartas, 563 00:32:27,800 --> 00:32:29,600 Speaker 2: and all the ones that come from the patient them cells, 564 00:32:29,640 --> 00:32:33,440 Speaker 2: that whole apparatus to collect the T cells, to manage 565 00:32:33,480 --> 00:32:38,240 Speaker 2: the to and fro. That actually is pretty rigorous, and 566 00:32:39,120 --> 00:32:42,360 Speaker 2: there are accrediting bodies who make sure that that's done 567 00:32:42,400 --> 00:32:44,560 Speaker 2: all right, because you have to track the cells back 568 00:32:44,640 --> 00:32:47,320 Speaker 2: and forth. You can't get lost in the case of 569 00:32:47,320 --> 00:32:51,200 Speaker 2: an off the shelf analogeneic another word is off the shelf. 570 00:32:51,680 --> 00:32:54,360 Speaker 2: We could it's just we just send the product to 571 00:32:54,440 --> 00:32:54,920 Speaker 2: the patient. 572 00:32:55,160 --> 00:32:57,760 Speaker 1: And aligenetic just means it doesn't have to come from 573 00:32:57,800 --> 00:33:02,200 Speaker 1: your body, comes from somebody else, right, somebody else's T cells, right, correct, 574 00:33:02,560 --> 00:33:03,800 Speaker 1: So go ahead, I'm sorry. 575 00:33:03,880 --> 00:33:08,880 Speaker 2: So we can actually send our products to the hospitals, 576 00:33:08,920 --> 00:33:13,360 Speaker 2: the suburban, the rural hospitals where the patients receive their care. 577 00:33:13,880 --> 00:33:18,360 Speaker 2: And in fact, in our Alpha three program where we're 578 00:33:18,440 --> 00:33:23,200 Speaker 2: using this new technique of MRD to find patients who 579 00:33:23,240 --> 00:33:26,760 Speaker 2: are very high risk of relapse, those patients are remaining 580 00:33:26,840 --> 00:33:30,720 Speaker 2: with their local oncologists and they're completing their frontline care, 581 00:33:31,240 --> 00:33:33,280 Speaker 2: they're getting this MRD test, they're found to be at 582 00:33:33,320 --> 00:33:35,760 Speaker 2: high risk of relapse, and instead of being referred at 583 00:33:35,760 --> 00:33:38,680 Speaker 2: that point to the big academic center maybe hundreds of 584 00:33:38,680 --> 00:33:41,560 Speaker 2: miles away, we enroll them into the trial and we 585 00:33:41,680 --> 00:33:45,800 Speaker 2: just shipped the cart cells right to that practice. And 586 00:33:45,840 --> 00:33:49,320 Speaker 2: in fact, many of the clinicians on our trial are 587 00:33:49,760 --> 00:33:52,920 Speaker 2: giving Carte cells for the very first time. They've decided 588 00:33:53,080 --> 00:33:57,040 Speaker 2: at their practice to not invest in the infrastructure required 589 00:33:57,080 --> 00:34:00,600 Speaker 2: for the autologous programs, but for an allergen off the 590 00:34:00,640 --> 00:34:03,160 Speaker 2: shelf program, they have everything that they need ready to go. 591 00:34:03,520 --> 00:34:05,880 Speaker 2: So these patients now are getting access to this life 592 00:34:06,200 --> 00:34:10,239 Speaker 2: modality simply because we can just ship it right from 593 00:34:10,239 --> 00:34:10,840 Speaker 2: our warehouse. 594 00:34:10,920 --> 00:34:14,120 Speaker 1: What is the most important thing for patients and their 595 00:34:14,200 --> 00:34:19,200 Speaker 1: doctors to know about this exciting new possible therapy for 596 00:34:20,160 --> 00:34:22,560 Speaker 1: recurrence early in the game. 597 00:34:23,040 --> 00:34:25,440 Speaker 2: So the most important thing I think for patients and 598 00:34:25,480 --> 00:34:30,080 Speaker 2: doctors to know is that we have new techniques to 599 00:34:30,239 --> 00:34:33,520 Speaker 2: assess disease at the end of treatment, not just pet 600 00:34:33,520 --> 00:34:37,080 Speaker 2: scans and cat scans. We actually have this new class 601 00:34:37,080 --> 00:34:40,560 Speaker 2: of blood tests called MRD tests that will really give 602 00:34:40,600 --> 00:34:43,320 Speaker 2: you a much better prognosis of your likelihood of relapse. 603 00:34:44,000 --> 00:34:48,160 Speaker 2: Right now, the only option for treatment is in the 604 00:34:48,200 --> 00:34:51,640 Speaker 2: Alpha three clinical trial. So if you're a patient or 605 00:34:51,680 --> 00:34:53,960 Speaker 2: you're a doctor who takes care of patients with diffuse 606 00:34:54,040 --> 00:34:58,680 Speaker 2: large B celempoma, ask about the MRD test, Ask about 607 00:34:58,719 --> 00:35:01,960 Speaker 2: the Alpha three clinical trial. Well, because we are really 608 00:35:02,320 --> 00:35:04,879 Speaker 2: it's not widely available. We do believe it eventually will 609 00:35:04,880 --> 00:35:07,120 Speaker 2: be wildly available, but we're really at the cutting edge 610 00:35:07,120 --> 00:35:09,880 Speaker 2: here and we want to get these patients access to 611 00:35:09,880 --> 00:35:13,560 Speaker 2: the clinical trial enrollment to again, hopefully if they're in 612 00:35:13,600 --> 00:35:16,360 Speaker 2: that very high risk of relapse, that third of patients, 613 00:35:16,400 --> 00:35:18,640 Speaker 2: we can find them and treat them when we have 614 00:35:18,719 --> 00:35:19,799 Speaker 2: the best chance of care. 615 00:35:20,040 --> 00:35:22,040 Speaker 1: And patients need to be aware of this so they 616 00:35:22,040 --> 00:35:24,480 Speaker 1: can make sure their doctors give them this test. 617 00:35:24,680 --> 00:35:30,200 Speaker 2: Oftentimes, it's remarkable, Katie, as you may know how important 618 00:35:30,360 --> 00:35:33,680 Speaker 2: the patient's questions and opinions are in determining the care 619 00:35:33,800 --> 00:35:36,480 Speaker 2: and walking in and saying to your doctor, Hey, you 620 00:35:36,520 --> 00:35:39,120 Speaker 2: know I heard about this new MRD test that will 621 00:35:39,160 --> 00:35:40,960 Speaker 2: tell me whether my disease is going to come back 622 00:35:41,040 --> 00:35:43,640 Speaker 2: or not. What can you tell me, doc about this? 623 00:35:44,000 --> 00:35:47,239 Speaker 2: Just that conversation that one question often will lead to 624 00:35:49,360 --> 00:35:51,240 Speaker 2: a patient finding a way into the clinical trial? 625 00:35:51,400 --> 00:35:53,719 Speaker 1: Is this only available to people who have a high 626 00:35:53,840 --> 00:35:56,719 Speaker 1: risk of relapse. Let's say a patient comes in and 627 00:35:56,800 --> 00:36:00,359 Speaker 1: they have I don't know, one of the blood cans 628 00:36:00,400 --> 00:36:04,080 Speaker 1: you mentioned. Can they just go ahead and get the 629 00:36:04,280 --> 00:36:09,520 Speaker 1: allogeneic therapy? Is there any advantage of using your own 630 00:36:09,600 --> 00:36:13,640 Speaker 1: T cells over kind of what might be more widely available. 631 00:36:14,360 --> 00:36:18,000 Speaker 2: So right now, the only time that you would get 632 00:36:18,239 --> 00:36:20,879 Speaker 2: a product made from your own T cells is if 633 00:36:20,920 --> 00:36:24,319 Speaker 2: your disease has come fully back, so in May. 634 00:36:24,560 --> 00:36:27,880 Speaker 1: What about your very when you're initially diagnosed. 635 00:36:27,480 --> 00:36:30,720 Speaker 2: So right now there is a couple of clinical trials 636 00:36:30,760 --> 00:36:34,600 Speaker 2: testing whether the patient's own T cells made into car 637 00:36:34,680 --> 00:36:38,200 Speaker 2: T cells can actually work in what we say are 638 00:36:38,280 --> 00:36:40,480 Speaker 2: very high risk patients. So ones that we know are 639 00:36:40,480 --> 00:36:44,919 Speaker 2: going to have a tough time. But for the most part, 640 00:36:45,239 --> 00:36:49,160 Speaker 2: patients with blood cancers typically often are cured. In fact 641 00:36:49,160 --> 00:36:51,880 Speaker 2: that the case of non Hodgin's lymphoma, two thirds of 642 00:36:51,920 --> 00:36:56,920 Speaker 2: the patients are cured with standard frontline chemotherapy. And so 643 00:36:57,560 --> 00:37:00,360 Speaker 2: when you get to the end of that, the issue is, 644 00:37:00,440 --> 00:37:02,839 Speaker 2: right now we don't really know who's cured and who isn't. 645 00:37:02,960 --> 00:37:05,200 Speaker 2: All we can do is wait and we just scan 646 00:37:05,320 --> 00:37:08,000 Speaker 2: these patients every three months and wait for their tumor 647 00:37:08,080 --> 00:37:10,879 Speaker 2: to come back. With this new test that we have, 648 00:37:11,000 --> 00:37:14,920 Speaker 2: this ultra sensitive MRD test minimal residual disease, we can 649 00:37:14,960 --> 00:37:17,440 Speaker 2: actually pick you know, if we've got two patients who 650 00:37:17,520 --> 00:37:20,360 Speaker 2: both look in complete remission, one of them is MRD 651 00:37:20,480 --> 00:37:23,640 Speaker 2: positive and one is MRD negative, we know that MRD 652 00:37:23,719 --> 00:37:27,160 Speaker 2: positive patient, which means we're finding little traces of cancer 653 00:37:27,239 --> 00:37:30,200 Speaker 2: DNA and that blood. That patient is at a very 654 00:37:30,239 --> 00:37:32,800 Speaker 2: high risk of relapse, and so it could really benefit 655 00:37:32,960 --> 00:37:37,240 Speaker 2: could really benefit court. So in that case, it's really tough. 656 00:37:37,280 --> 00:37:41,040 Speaker 2: You can't really make the car T cells the way 657 00:37:41,560 --> 00:37:45,120 Speaker 2: that we've done with the patients because the own car 658 00:37:45,160 --> 00:37:47,719 Speaker 2: T cells they don't really have a lot of T cells. 659 00:37:47,760 --> 00:37:51,799 Speaker 2: They've just finished their frontline therapy. Sometimes the disease can 660 00:37:51,800 --> 00:37:53,719 Speaker 2: come back within a matter of weeks, so while the 661 00:37:53,760 --> 00:37:56,560 Speaker 2: cells are being made, the tumor comes back. So this 662 00:37:56,640 --> 00:37:59,600 Speaker 2: is really a great opportunity for an off the shelf 663 00:37:59,640 --> 00:38:02,839 Speaker 2: product to just go. At the time that we get 664 00:38:02,880 --> 00:38:06,960 Speaker 2: that MRD result, we send the car T cells that 665 00:38:07,000 --> 00:38:08,640 Speaker 2: are made from healthy donor. They're all frozen in. 666 00:38:08,640 --> 00:38:10,800 Speaker 1: Our fop residual disease. 667 00:38:10,920 --> 00:38:13,640 Speaker 2: That's the term, they mop up the residual disease. So 668 00:38:14,000 --> 00:38:16,520 Speaker 2: that is the clinical trial that we are running right now. 669 00:38:16,600 --> 00:38:20,360 Speaker 2: So this is a very fascinating area of oncology because 670 00:38:20,360 --> 00:38:24,560 Speaker 2: we are using these enhanced techniques like MRD to identify 671 00:38:24,600 --> 00:38:28,239 Speaker 2: the patients who are likely to relapse. So far, we're 672 00:38:28,280 --> 00:38:32,160 Speaker 2: only studying that in clinical trials, and so the Alpha 673 00:38:32,239 --> 00:38:34,920 Speaker 2: three trial is the one that Alergen is running, and 674 00:38:34,960 --> 00:38:37,759 Speaker 2: it's designed exactly that way. So if we find a 675 00:38:37,800 --> 00:38:40,960 Speaker 2: patient who looks to be in remission based on scans 676 00:38:41,000 --> 00:38:44,480 Speaker 2: and they feel great, but if they're MRD positive, we're 677 00:38:44,480 --> 00:38:46,480 Speaker 2: pretty sure that patient's disease is going to come back, 678 00:38:46,520 --> 00:38:47,919 Speaker 2: and it might come back in a matter of weeks 679 00:38:48,000 --> 00:38:51,240 Speaker 2: or months. So we're treating those patients in our clinical 680 00:38:51,280 --> 00:38:54,080 Speaker 2: trial right now with our off the shelf car te cells. 681 00:38:54,280 --> 00:38:59,080 Speaker 1: This is potentially a life saving intervention because if you 682 00:38:59,239 --> 00:39:04,720 Speaker 1: wait until the disease appears on a cat scan, sometimes 683 00:39:04,840 --> 00:39:09,200 Speaker 1: it's too late and the car T therapy isn't as effective. 684 00:39:09,280 --> 00:39:12,600 Speaker 2: That's exactly it. So if we were essentially bringing car 685 00:39:12,680 --> 00:39:16,720 Speaker 2: T cells to the patient much sooner, when they stand 686 00:39:16,760 --> 00:39:20,840 Speaker 2: a greater chance of benefiting, they probably will have fewer 687 00:39:20,880 --> 00:39:23,480 Speaker 2: side effects because side effects are related to how much 688 00:39:23,560 --> 00:39:25,360 Speaker 2: cancer is in the body at the time of infusion. 689 00:39:25,760 --> 00:39:28,920 Speaker 2: And really the goal here is to cure these patients 690 00:39:28,960 --> 00:39:31,080 Speaker 2: before they ever have to suffer that relapse. And that 691 00:39:31,160 --> 00:39:34,640 Speaker 2: is what makes Alpha three such a revolutionary design. 692 00:39:34,920 --> 00:39:40,640 Speaker 1: If someone's cancer has recurred and they do have evidence 693 00:39:40,680 --> 00:39:44,880 Speaker 1: of disease, right, then they can source car T therapy. 694 00:39:45,000 --> 00:39:48,120 Speaker 2: Now in that minority of cases right where there's about 695 00:39:48,200 --> 00:39:51,359 Speaker 2: fifteen to twenty percent of patients who are fortunate enough 696 00:39:51,360 --> 00:39:54,360 Speaker 2: to be have the stars aligned, yes, that would be 697 00:39:54,719 --> 00:39:57,040 Speaker 2: the standard second line, right, but there are a lot. 698 00:39:56,920 --> 00:40:00,600 Speaker 1: Of people who have this happen and they don't have access. 699 00:40:00,800 --> 00:40:02,560 Speaker 1: And that's what you're trying to tackle. 700 00:40:02,680 --> 00:40:04,520 Speaker 2: That's one hundred percent what we're trying to tackle. 701 00:40:04,680 --> 00:40:06,960 Speaker 1: So how are you trying? How are you tackling it? 702 00:40:07,120 --> 00:40:09,440 Speaker 1: Are you can you go the seven to eleven and say, 703 00:40:09,480 --> 00:40:11,080 Speaker 1: I like those card cells. 704 00:40:11,320 --> 00:40:16,120 Speaker 2: No. So, this MRD story is developing across oncology, not 705 00:40:16,200 --> 00:40:18,520 Speaker 2: just in blood cancers where we're studying with Alpha three, 706 00:40:19,040 --> 00:40:21,520 Speaker 2: and so patients more and more are starting to ask 707 00:40:21,560 --> 00:40:24,160 Speaker 2: for these tests. More tests are becoming available. So even 708 00:40:24,200 --> 00:40:27,680 Speaker 2: in your community oncology practices, at the end of a 709 00:40:27,719 --> 00:40:31,799 Speaker 2: treatment cycle. The oncologist will often order this MRD test 710 00:40:31,800 --> 00:40:34,000 Speaker 2: to see how do we do did we get every 711 00:40:34,080 --> 00:40:37,400 Speaker 2: last cell? You know, in a manner of speaking. And 712 00:40:37,480 --> 00:40:42,080 Speaker 2: so if in the context of our clinical trial, they 713 00:40:42,120 --> 00:40:44,640 Speaker 2: send this test, which is very sensitive, and they find 714 00:40:44,640 --> 00:40:48,640 Speaker 2: that it is that there is residual tumor there, then 715 00:40:48,719 --> 00:40:51,360 Speaker 2: that patient is potentially eligible to enroll in our study. 716 00:40:51,480 --> 00:40:53,600 Speaker 2: And so what we're trying to see here is whether 717 00:40:54,360 --> 00:40:58,520 Speaker 2: us treating the patient when they only have that molecular 718 00:40:58,600 --> 00:41:02,000 Speaker 2: disease nothing on scan the MRD alone, if we treat 719 00:41:02,000 --> 00:41:05,520 Speaker 2: with our car T cells at that moment, are we 720 00:41:05,640 --> 00:41:08,640 Speaker 2: able to cure the patient and have the disease never 721 00:41:08,680 --> 00:41:09,160 Speaker 2: come back. 722 00:41:09,920 --> 00:41:14,840 Speaker 1: Car T therapy is really effective when there's residual disease? 723 00:41:15,080 --> 00:41:18,799 Speaker 1: Is it also effective, Zach if your tumor comes back 724 00:41:18,840 --> 00:41:20,360 Speaker 1: and you see something on a scan. 725 00:41:21,160 --> 00:41:24,560 Speaker 2: So almost all the data that we have so far, 726 00:41:24,880 --> 00:41:27,520 Speaker 2: including all the approvals for the car T cells, have 727 00:41:27,640 --> 00:41:30,480 Speaker 2: been in that exact situation when your tumor has come 728 00:41:30,520 --> 00:41:32,920 Speaker 2: fully back. So this would be a time when we 729 00:41:32,920 --> 00:41:35,360 Speaker 2: would take a patient to a BOEM or transplant, for example, 730 00:41:35,400 --> 00:41:38,319 Speaker 2: if you gave them car T cells instead. This is 731 00:41:38,320 --> 00:41:40,840 Speaker 2: what has led to those miraculous outcomes that we discussed 732 00:41:40,880 --> 00:41:44,920 Speaker 2: a little early when their tumoror has come back. But 733 00:41:45,040 --> 00:41:47,799 Speaker 2: what we do know is that car T cells work 734 00:41:47,920 --> 00:41:52,040 Speaker 2: better when you have very little disease. We've known that 735 00:41:52,160 --> 00:41:54,879 Speaker 2: for a long long time. So what the Alpha three 736 00:41:54,920 --> 00:41:58,120 Speaker 2: trial is designed to do is actually find the patients 737 00:41:58,120 --> 00:42:03,359 Speaker 2: with the lowest imaginable amount of disease, just the microscopic disease. 738 00:42:03,120 --> 00:42:05,280 Speaker 1: And what percentage of patients are those. 739 00:42:05,600 --> 00:42:11,520 Speaker 2: So most likely ninety to probably close to one hundred 740 00:42:11,520 --> 00:42:15,840 Speaker 2: percent of patients who eventually relapse will have an interval 741 00:42:15,880 --> 00:42:19,120 Speaker 2: of time where they have MRD only disease, where you 742 00:42:19,160 --> 00:42:21,480 Speaker 2: can only find it in the blood using a very 743 00:42:21,480 --> 00:42:25,719 Speaker 2: specific molecular test. Relapse doesn't typically happen out of the 744 00:42:25,760 --> 00:42:29,160 Speaker 2: clear blue sky. So if we time things well, as 745 00:42:29,160 --> 00:42:31,839 Speaker 2: we're trying to do with Alpha three, the patients get 746 00:42:31,840 --> 00:42:35,759 Speaker 2: the MRD test at the right time, their doctors order it. 747 00:42:36,239 --> 00:42:39,000 Speaker 2: If it's found to be positive, we act on it. 748 00:42:39,120 --> 00:42:41,760 Speaker 2: In this case, we enroll in our clinical trial. But eventually, 749 00:42:41,760 --> 00:42:44,879 Speaker 2: if this trial is positive, we hope that this off 750 00:42:44,920 --> 00:42:48,600 Speaker 2: the shelf car T cell will be available commercially, so 751 00:42:48,680 --> 00:42:50,319 Speaker 2: this could become a standard of care. 752 00:42:50,680 --> 00:42:54,480 Speaker 1: But you're hoping that if you're able to introduce CARTI 753 00:42:54,719 --> 00:42:59,160 Speaker 1: therapy much earlier with the help of this test that 754 00:42:59,200 --> 00:43:03,080 Speaker 1: will indicate your risk of relapse, that it is much 755 00:43:03,120 --> 00:43:03,800 Speaker 1: more effective. 756 00:43:03,880 --> 00:43:06,720 Speaker 2: That's one hundred percent. If we can find these folks 757 00:43:06,960 --> 00:43:10,319 Speaker 2: when there are disease is at its weakest point and 758 00:43:10,680 --> 00:43:13,760 Speaker 2: mop it up with the Carte cells at their local 759 00:43:13,800 --> 00:43:17,880 Speaker 2: institution without a big onerous referral or blood collection, just 760 00:43:17,920 --> 00:43:20,600 Speaker 2: take care of it right then and there. Does that 761 00:43:20,640 --> 00:43:24,040 Speaker 2: improve long term cure? Does that improve outcomes and you 762 00:43:24,160 --> 00:43:29,560 Speaker 2: prevent the horrific relapse. That's a terrible moment for everybody 763 00:43:29,920 --> 00:43:33,120 Speaker 2: when you think you're cured of your lymphoma and then 764 00:43:33,160 --> 00:43:36,480 Speaker 2: suddenly you go to a clinic one day and you 765 00:43:36,520 --> 00:43:38,839 Speaker 2: get a scan and the doctor comes in and says 766 00:43:38,840 --> 00:43:41,920 Speaker 2: that your cancers come back. What we're trying to do 767 00:43:42,040 --> 00:43:46,600 Speaker 2: with this trial by deploying these Carte cells early, is 768 00:43:46,680 --> 00:43:49,080 Speaker 2: to prevent that from ever happening and get those patients 769 00:43:49,080 --> 00:43:51,479 Speaker 2: into a cured state. That is really what we're trying 770 00:43:51,520 --> 00:43:55,360 Speaker 2: to do. If we are successful here, this will be 771 00:43:55,640 --> 00:44:02,400 Speaker 2: the most impactful change to first line outcomes in almost 772 00:44:02,440 --> 00:44:05,840 Speaker 2: thirty years. That's how hard it's been to improve outcomes 773 00:44:06,120 --> 00:44:09,880 Speaker 2: in frontline non HODGKINSLM foma. So Alpha three is really 774 00:44:10,040 --> 00:44:12,040 Speaker 2: potential to be revolutionary here. 775 00:44:12,480 --> 00:44:16,399 Speaker 1: Most people are cured with the standard of care when 776 00:44:16,440 --> 00:44:20,319 Speaker 1: you have these blood cancers, correct, correct, But there is 777 00:44:20,360 --> 00:44:23,360 Speaker 1: a subset of people who relapse, and we don't know 778 00:44:23,400 --> 00:44:24,839 Speaker 1: who they are, right and. 779 00:44:24,719 --> 00:44:27,400 Speaker 2: It's about a third about a third of patients with 780 00:44:27,800 --> 00:44:31,160 Speaker 2: the most common type of non HODGKINSLM foma that we're studying, 781 00:44:31,160 --> 00:44:35,440 Speaker 2: it's a disease called diffuse large B cellmphoma, pretty common 782 00:44:35,480 --> 00:44:39,680 Speaker 2: blood cancer. About ninety percent of these patients will achieve 783 00:44:39,719 --> 00:44:43,520 Speaker 2: a remission to frontline care, which is the standard regimen 784 00:44:43,520 --> 00:44:47,120 Speaker 2: that we've been given for thirty years, but a third 785 00:44:47,200 --> 00:44:50,440 Speaker 2: of those patients will eventually have a relapse. And the 786 00:44:50,480 --> 00:44:52,480 Speaker 2: standard of care right now is you get to the 787 00:44:52,640 --> 00:44:56,279 Speaker 2: end and then you watch and wait. These patients will 788 00:44:56,320 --> 00:44:58,839 Speaker 2: come back every three months for a clinic visit, they 789 00:44:58,840 --> 00:45:01,400 Speaker 2: get scanned every three to six months, and essentially you're 790 00:45:01,480 --> 00:45:04,080 Speaker 2: kind of on pins and needles waiting for this tumor 791 00:45:04,160 --> 00:45:04,560 Speaker 2: to recur. 792 00:45:04,840 --> 00:45:07,400 Speaker 1: Can you tell me a little bit, Zach, about how 793 00:45:07,480 --> 00:45:10,760 Speaker 1: this specific trial that you're running came about. 794 00:45:12,080 --> 00:45:17,080 Speaker 2: Certainly a very cutting edge trial and in fact, even 795 00:45:17,239 --> 00:45:19,799 Speaker 2: just a few years ago, we wouldn't have been able 796 00:45:19,800 --> 00:45:22,319 Speaker 2: to run this trial. There really needed to be a 797 00:45:22,400 --> 00:45:26,120 Speaker 2: confluence of new technologies all coming to the four at 798 00:45:26,280 --> 00:45:30,040 Speaker 2: roughly the same time. So the example first that I'll 799 00:45:30,320 --> 00:45:35,799 Speaker 2: lead with is the MRD platform. This test and this 800 00:45:35,880 --> 00:45:39,000 Speaker 2: class of tests is pretty new. It's only been around 801 00:45:39,040 --> 00:45:41,640 Speaker 2: for a few years in this iteration that it is 802 00:45:41,719 --> 00:45:44,600 Speaker 2: right now, and it's only recently begun to be used 803 00:45:44,600 --> 00:45:48,680 Speaker 2: in patients with lymphoma. So that advent was something that 804 00:45:48,760 --> 00:45:52,480 Speaker 2: was required. The next big thing was because we need 805 00:45:52,520 --> 00:45:55,759 Speaker 2: to act so quickly on the MRD positive result. You know, 806 00:45:55,800 --> 00:46:00,279 Speaker 2: we can't spend months referring patients to cartee centers having 807 00:46:00,360 --> 00:46:03,440 Speaker 2: their products manufactured. We have to act really within days. 808 00:46:04,120 --> 00:46:06,760 Speaker 2: We needed to have an aalogenetic off the shelf therapy 809 00:46:06,840 --> 00:46:07,239 Speaker 2: ready to go. 810 00:46:07,400 --> 00:46:10,760 Speaker 1: And when you say allogenetic, just remind people what that needs. 811 00:46:10,880 --> 00:46:13,600 Speaker 2: That means it's coming from a healthy donor, but it 812 00:46:13,680 --> 00:46:17,120 Speaker 2: means from a practical perspective, from a patient perspective, that 813 00:46:17,160 --> 00:46:18,279 Speaker 2: it's off the shelf. 814 00:46:18,239 --> 00:46:20,080 Speaker 1: And it's ready, it's ready to need. 815 00:46:19,960 --> 00:46:23,040 Speaker 2: It when the patient needs it. It's ready to go. 816 00:46:23,080 --> 00:46:25,160 Speaker 2: It can be there literally in days because time is 817 00:46:25,160 --> 00:46:27,680 Speaker 2: of the time is of the essence. For these MRD 818 00:46:27,800 --> 00:46:31,640 Speaker 2: positive patients, we know their disease could come back any day, 819 00:46:32,719 --> 00:46:35,160 Speaker 2: and it actually can happen very very quickly within weeks, 820 00:46:35,960 --> 00:46:38,239 Speaker 2: so we really have to act very rapidly on. 821 00:46:38,160 --> 00:46:40,640 Speaker 1: That is the reason a trial like this hasn't been 822 00:46:40,719 --> 00:46:46,279 Speaker 1: done before, because all these technologies didn't exist and all 823 00:46:46,280 --> 00:46:48,680 Speaker 1: the pieces of the puzzle weren't there yet. 824 00:46:49,640 --> 00:46:53,760 Speaker 2: That is essentially it. We needed enough time for these 825 00:46:53,800 --> 00:46:57,719 Speaker 2: technologies independently to mature to a point where we could 826 00:46:57,760 --> 00:47:01,120 Speaker 2: combine them into what is really a very cutting edge 827 00:47:01,120 --> 00:47:05,080 Speaker 2: and revolutionary design. To be able to act upon a 828 00:47:05,160 --> 00:47:08,239 Speaker 2: disease before you can see it on a scan. That 829 00:47:08,360 --> 00:47:10,520 Speaker 2: is kind of a new concept, but it makes a 830 00:47:10,560 --> 00:47:15,319 Speaker 2: lot of sense because drugs and cart cells tend to 831 00:47:15,320 --> 00:47:17,400 Speaker 2: work better when there's not very much cancer around. 832 00:47:18,160 --> 00:47:21,560 Speaker 1: Let's talk about the patients that will benefit from this 833 00:47:21,880 --> 00:47:27,720 Speaker 1: right now. Is it a specific lymphoma patient you're looking 834 00:47:27,800 --> 00:47:31,000 Speaker 1: for to participate in this trial? Is it people with 835 00:47:31,160 --> 00:47:33,440 Speaker 1: leukemia who are you looking for? 836 00:47:33,960 --> 00:47:37,680 Speaker 2: Yes? So, in the Alpha three trial, it is for 837 00:47:37,840 --> 00:47:41,680 Speaker 2: a group of patients with non Hodgkins lymphoma, and it's 838 00:47:41,719 --> 00:47:45,600 Speaker 2: actually the greatest or most prevalent non Hodginson foma, which 839 00:47:45,640 --> 00:47:49,040 Speaker 2: is a disease called diffuse large diffuse large B cell 840 00:47:49,080 --> 00:47:53,560 Speaker 2: lymphoma or DLBCL. So that is the main type of 841 00:47:53,600 --> 00:47:56,680 Speaker 2: cancer that is eligible for Alpha three. There are a 842 00:47:56,680 --> 00:48:00,319 Speaker 2: couple other non Hodginson foma which are less common, but 843 00:48:00,400 --> 00:48:02,360 Speaker 2: that's the majority of patients that we're looking for at 844 00:48:02,400 --> 00:48:03,600 Speaker 2: DLBCL patients. 845 00:48:03,800 --> 00:48:07,800 Speaker 1: What is the standard of care right now for people 846 00:48:08,040 --> 00:48:12,280 Speaker 1: with diffuse large B cellomphoma. 847 00:48:12,160 --> 00:48:17,480 Speaker 2: So everyone gets the same treatment. It's a five drug 848 00:48:17,520 --> 00:48:24,799 Speaker 2: regimen that's chemotherapy our CHOP, and it's given every three weeks. 849 00:48:24,880 --> 00:48:27,759 Speaker 2: Those five drugs are given together, all on the same day, 850 00:48:29,400 --> 00:48:32,960 Speaker 2: six times three weeks apart, and at the end of 851 00:48:32,960 --> 00:48:37,200 Speaker 2: that six cycles of our CHOP, you undergo a cat 852 00:48:37,200 --> 00:48:40,600 Speaker 2: scan to see whether your disease has gone into remission 853 00:48:40,680 --> 00:48:44,279 Speaker 2: or whether it hasn't. The majority of patients will have 854 00:48:44,480 --> 00:48:47,480 Speaker 2: entered or remission, and about two thirds of them are cured. 855 00:48:48,160 --> 00:48:50,480 Speaker 2: They never need another drop of treatment ever again in 856 00:48:50,520 --> 00:48:52,239 Speaker 2: their lives and they're not going to hear from their 857 00:48:52,320 --> 00:48:56,200 Speaker 2: lymphoma again. There is a third of patients, however, who 858 00:48:56,280 --> 00:48:59,120 Speaker 2: will eventually have their disease come back and right now. 859 00:48:59,200 --> 00:49:02,760 Speaker 2: The problem is with our PET scans and our cat scans, 860 00:49:03,080 --> 00:49:06,480 Speaker 2: the way we measure disease activity is we can't distinguish 861 00:49:06,480 --> 00:49:09,080 Speaker 2: who's who right when they complete treatment. 862 00:49:09,480 --> 00:49:13,839 Speaker 1: So will this expand to other blood cancers do you think, 863 00:49:13,920 --> 00:49:18,160 Speaker 1: in other words, leukemia patients or other people who might 864 00:49:18,280 --> 00:49:18,719 Speaker 1: need it. 865 00:49:19,680 --> 00:49:26,560 Speaker 2: Absolutely so. If the Alpha three trial is successful and 866 00:49:26,680 --> 00:49:30,640 Speaker 2: we are able to show that preventing relapse leads to cures, 867 00:49:31,920 --> 00:49:33,560 Speaker 2: I think it would make a lot of sense for 868 00:49:33,600 --> 00:49:37,160 Speaker 2: Allergen or other drug developers to start to replicate this 869 00:49:37,280 --> 00:49:41,640 Speaker 2: study in other settings like B cell leukemias, like other 870 00:49:41,719 --> 00:49:45,799 Speaker 2: types of lymphoma. It is such a revolutionary way to 871 00:49:45,920 --> 00:49:51,120 Speaker 2: look at treating cancer, preventing relapse before it occurs, and 872 00:49:51,239 --> 00:49:55,319 Speaker 2: using this MRD test to really segregate patients who are 873 00:49:55,560 --> 00:49:58,480 Speaker 2: very high risk versus those who are probably cured and 874 00:49:58,520 --> 00:50:00,520 Speaker 2: you don't need to worry about them as much anymore. 875 00:50:00,840 --> 00:50:05,839 Speaker 1: What about beyond oncology, do you see this therapy as 876 00:50:05,960 --> 00:50:08,160 Speaker 1: efficacious for other diseases? 877 00:50:10,120 --> 00:50:14,000 Speaker 2: So we have seen the last three years an explosion 878 00:50:14,320 --> 00:50:19,359 Speaker 2: of work into treating autoimmune disorders with cart cells. So 879 00:50:19,520 --> 00:50:24,120 Speaker 2: diseases like lupus and systemic sclerosis are scleroderma and others 880 00:50:25,280 --> 00:50:28,680 Speaker 2: multiple sclerosis, for example, there's been some proof of concept there. 881 00:50:28,719 --> 00:50:34,839 Speaker 2: So these same products that have demonstrated such power in 882 00:50:34,920 --> 00:50:39,800 Speaker 2: oncology are now bringing to patients with refractory autoimmune disease 883 00:50:40,800 --> 00:50:43,600 Speaker 2: for the first time in many years, an opportunity for 884 00:50:43,640 --> 00:50:47,000 Speaker 2: a drug free remission. These patients are entering remissions, their 885 00:50:47,040 --> 00:50:50,160 Speaker 2: disease activity is going significantly down, if not all the 886 00:50:50,160 --> 00:50:52,440 Speaker 2: way down to zero, and they're able to come off 887 00:50:52,440 --> 00:50:54,239 Speaker 2: of their drugs that they've been on for in some 888 00:50:54,320 --> 00:50:59,120 Speaker 2: cases decades. This is poised to become yet another revolution 889 00:50:59,520 --> 00:51:02,960 Speaker 2: in car just like we saw in oncology, and so 890 00:51:03,280 --> 00:51:06,000 Speaker 2: I think that it's a very exciting moment here. There's 891 00:51:06,320 --> 00:51:09,480 Speaker 2: hundreds upon hundreds of thousands of patients who could potentially 892 00:51:09,560 --> 00:51:14,160 Speaker 2: benefit from this intervention, and so companies like Allergeen are 893 00:51:14,400 --> 00:51:17,799 Speaker 2: trying to come up with ways that are tailored to 894 00:51:17,920 --> 00:51:24,480 Speaker 2: this patient segment that is oncology patients are different rheumatology patients, 895 00:51:24,480 --> 00:51:28,080 Speaker 2: and trying to meet the needs of those individuals directly 896 00:51:28,200 --> 00:51:29,960 Speaker 2: through our product design and study design. 897 00:51:30,920 --> 00:51:35,200 Speaker 1: Well, it's really thanks to scientists like you who work 898 00:51:35,360 --> 00:51:39,960 Speaker 1: tirelessly trying to figure out how to help patients so on, 899 00:51:40,040 --> 00:51:43,520 Speaker 1: behalf of so many people who I'm sure might be 900 00:51:43,640 --> 00:51:48,520 Speaker 1: listening to this and really being grateful for your work. 901 00:51:48,680 --> 00:51:52,359 Speaker 1: I'd like to say thank you first and foremost.
