Latest / Making Medicine / AI in Drug Discovery: What Works, What’s Hype & What Comes Next
Transcript
- 0:00Speaker 1: At Making Medicine, we're reporting on the headlines, not making
- 0:03Speaker 1: medical recommendations. For personal health questions, always ask your doctor.
- 0:08Speaker 1: Nothing in this episode constitutes investment, financial, or legal advice.
- 0:13Speaker 1: Consult your own advisors before making decisions.
- 0:16Speaker 2: Clinical trial design, I think AI is going to be
- 0:18Speaker 2: very powerful, but you have to be very deliberate about
- 0:22Speaker 2: asking your question, and you have to make sure that
- 0:24Speaker 2: the Context underneath your feet isn't sifting unwittingly, right? That's
- 0:28Speaker 2: where AI becomes very bad. If the contextual rules change
- 0:32Speaker 2: and you don't know they've changed, then AI is no
- 0:35Speaker 2: better than guessing.
- 0:41Speaker 1: Welcome back to the Making Medicine podcast, where science, policy,
- 0:45Speaker 1: and innovation meet. I'm your host, John Stanford. Today, we're
- 0:49Speaker 1: welcoming back a friend of the show, an Incubate Advisory
- 0:52Speaker 1: Board member, Dr.
- 0:53Speaker 3: Tom Kaiser.
- 0:55Speaker 1: Tom is the co-founder and chief scientific officer of Avicenna Biosciences,
- 0:59Speaker 1: which uses machine learning to speed up the last mile
- 1:02Speaker 1: of small molecule drug discovery.
- 1:04Speaker 3: He's also now an operating partner.
- 1:06Speaker 1: At DCVC Bio, the deep tech life sciences venture firm
- 1:10Speaker 1: that led Avicenna's seed round. Before Avicenna, he led the
- 1:14Speaker 1: antivirals group in Emory's Leota Research Group, whose work has
- 1:18Speaker 1: produced more than 20 FDA-approved therapies. He's also been one
- 1:21Speaker 1: of the more credible voices cutting through all the AI
- 1:24Speaker 1: hype most recently in a must-read Biospace op-ed, arguing that
- 1:29Speaker 1: AI will only revolutionize drug discovery and development if we
- 1:32Speaker 1: play to its strengths. Today, we're catching up with him
- 1:35Speaker 1: on Avicenna's pipeline, what brought him to DCVC Bio, how
- 1:39Speaker 1: he sees China reshaping the competitive landscape, why the pill
- 1:43Speaker 1: penalty is still front of mind for companies like his,
- 1:46Speaker 1: and he gives an absolute masterclass on how AI can
- 1:50Speaker 1: and cannot reshape biotech. With that, let's get into the show. Tom,
- 1:56Speaker 1: welcome back to the show.
- 1:57Speaker 2: That's great to be here, John. Thanks for having me.
- 1:59Speaker 1: Well, our listeners who have heard you before, and we've
- 2:02Speaker 1: had you on to be a guru on all things biotech,
- 2:05Speaker 1: all things AI, they know you as Avicenna, but excitingly,
- 2:09Speaker 1: you're adding more hats since you were last on the show.
- 2:13Speaker 1: You've taken on not just the running of the company
- 2:16Speaker 1: and leading a company, but also being an operating partner
- 2:19Speaker 1: at DC VC bio, um, maybe jumping off there, what
- 2:24Speaker 1: made you take that leap and what are, what's different
- 2:27Speaker 1: now that you also wear an investor hat?
- 2:30Speaker 2: Yeah, well, it's, um, making that leap was really something
- 2:33Speaker 2: that was offered to me. Um, so John Hamer called
- 2:37Speaker 2: me up one day and he said, Hey, uh, do
- 2:39Speaker 2: you want to be an operating partner in our firm?
- 2:41Speaker 2: And I said, uh, sure. What does that mean? So
- 2:46Speaker 2: it wasn't an area that was really on my horizon, but, um, Yeah, it's,
- 2:51Speaker 2: it's a, it's a real privilege to join an exemplary team. The,
- 2:54Speaker 2: the DCVC, DCVC bio community is just, uh, it's, it's
- 2:59Speaker 2: chock full of really talented and nice people. It's a
- 3:02Speaker 2: rare combination, uh, to find, but, um, they're the institutional
- 3:07Speaker 2: investor in Avicenna. And so I think they really wanted
- 3:10Speaker 2: to bring some medicinal chemistry expertise and some machine learning
- 3:13Speaker 2: know-how into the firm to help evaluate all these exciting opportunities.
- 3:18Speaker 2: in emerging areas like molecular glues, is this really something
- 3:21Speaker 2: that we should invest in? And then also the rise
- 3:24Speaker 2: of the frontier model, what does this mean? How should
- 3:26Speaker 2: we think about it? So how has changed what I
- 3:32Speaker 2: do when I think about Avicenna and just biotech in general,
- 3:36Speaker 2: it's made it a tighter package in terms of presenting
- 3:40Speaker 2: the opportunity, the upside, where we're going, what's really the
- 3:44Speaker 2: innovation that we have to offer. But It's amazing to
- 3:47Speaker 2: see the vanguard of things that are just rolling out
- 3:51Speaker 2: of university. You get to kind of get a sneak
- 3:53Speaker 2: peek before they go non-stealth or where are people thinking
- 3:58Speaker 2: about what is going to be the new big thing.
- 4:01Speaker 2: So it's been really cool to see. And then also
- 4:04Speaker 2: coming in and trying to help companies tighten up their
- 4:08Speaker 2: IND packages and really select candidates. That's been fun. Just
- 4:13Speaker 2: good old-fashioned MedKim. Nothing fancy. Are we on the right
- 4:17Speaker 2: path for designing a medicine? You know, the old bread
- 4:19Speaker 2: and butter of what I was trained in before all
- 4:22Speaker 2: this AI stuff. So it's been great. I've really, really
- 4:26Speaker 2: just enjoyed it. It's been a lot of fun, a
- 4:29Speaker 2: lot of breadth, a lot of new stuff to see
- 4:31Speaker 2: and think about.
- 4:32Speaker 1: Is it changing anything? Does it change how you look
- 4:35Speaker 1: in the mirror from an Avicenna standpoint? Like, has your
- 4:39Speaker 1: perspective shifted of, oh, now I kind of get why
- 4:42Speaker 1: the investment community is asking this questions or they like
- 4:45Speaker 1: data presented this way?
- 4:47Speaker 3: Or is it all still pretty rote?
- 4:50Speaker 2: Yeah, we were really fortunate, Peter and I were, that
- 4:54Speaker 2: DCVC put so much into us. One of the entrepreneurs
- 4:58Speaker 2: in residence from DCVC Bio actually came into Avicenna. So
- 5:02Speaker 2: we had a very good idea early on of how
- 5:05Speaker 2: to present ourselves and how we need to package and
- 5:08Speaker 2: present data. And that's really a testament to Chris Meldrum.
- 5:13Speaker 2: And I think we've certainly thought more carefully about that.
- 5:18Speaker 2: As you get close to the clinic, the bar definitely
- 5:20Speaker 2: goes up quite a bit in terms of what investors
- 5:22Speaker 2: demand and expect. But I think it's, if anything, it's
- 5:27Speaker 2: made It's made it quite clear that what we're doing
- 5:31Speaker 2: in terms of focusing exclusively on candidate design is still
- 5:34Speaker 2: very rare. A lot of people want to do new biology,
- 5:38Speaker 2: new chemistry, and there's a lot of risk with that.
- 5:40Speaker 2: Whereas we want to do drug design, like exclusively clinical
- 5:44Speaker 2: candidate design. So it's been nice to really understand that
- 5:49Speaker 2: at a very high level and be able to pitch
- 5:52Speaker 2: that story a little bit more carefully and clearly.
- 5:54Speaker 1: Well, and the story is only getting better. So let's
- 5:56Speaker 1: dig a little deeper on Avicenna. My understanding is some
- 6:00Speaker 1: congratulations are in order as you've gotten some good news
- 6:04Speaker 1: out of the FDA on your pre-IND for first in
- 6:08Speaker 1: human trials around your ALS drug. Tell us a little
- 6:12Speaker 1: bit more about that and the good things happening at Avicenna.
- 6:15Speaker 2: Yeah. Thanks a bunch. I mean, it's always exciting when
- 6:18Speaker 2: you interact with regulators and they come back and say, yep,
- 6:21Speaker 2: you're on the right track, right?
- 6:23Speaker 3: That's a good sign.
- 6:24Speaker 2: That's what you hoped to hear. So we just got
- 6:28Speaker 2: our pre-IND response letter back, and it was very good. Basically,
- 6:34Speaker 2: that's when you lay out the last things that you're
- 6:36Speaker 2: going to do preclinically, your GLP talks, and then your
- 6:39Speaker 2: prototypical studies for your first in human. And you basically
- 6:42Speaker 2: ask the FDA, hey, this is the tox package that
- 6:46Speaker 2: we think we need in order to have a safety
- 6:48Speaker 2: profile to go first in human. What are the things
- 6:51Speaker 2: that we're missing, if any? And we got a very
- 6:54Speaker 2: clear answer that we're on the right track, that this
- 6:56Speaker 2: is a good package. So it's always exciting to, I mean,
- 7:01Speaker 2: we literally designed the molecule, we picked the target, we
- 7:04Speaker 2: picked the indication, we did everything in Avicenna. So five
- 7:08Speaker 2: years from literally turning the key to pre-IND is amazing.
- 7:12Speaker 2: And it's really exciting that we're going to go into
- 7:15Speaker 2: an area of huge need like ALS and hopefully have
- 7:19Speaker 2: a disease-modifying drug there. So it's a testament to the
- 7:23Speaker 2: power of AI in drug design when you use AI correctly, right?
- 7:27Speaker 2: And we can talk about that a little bit, but
- 7:29Speaker 2: it's a very exciting time. It's amazing that we've had
- 7:33Speaker 2: such a wonderful group of people that are very skilled
- 7:37Speaker 2: at what they do. It's a tiny number of people
- 7:39Speaker 2: that are really pushing us forward. And normally you have
- 7:42Speaker 2: We were able to do this with $ 25 million. There
- 7:45Speaker 2: are companies that have raised $ 250 million, half a billion dollars,
- 7:49Speaker 2: and they're further behind than we are. So really exciting
- 7:53Speaker 2: and proof of the fact that we're doing something neat.
- 7:56Speaker 1: Well, and I want to stay there because, yeah, you
- 8:00Speaker 1: are sort of doing this on a shoestring budget, and
- 8:03Speaker 1: maybe that's part of the story around AI because, as
- 8:05Speaker 1: you've said– You have 20 some odd million put into this.
- 8:10Speaker 1: And not only do you have your rock inhibitors, you
- 8:12Speaker 1: have your CSF1R program.
- 8:15Speaker 3: So you've got.
- 8:16Speaker 1: These things coming along. What allowed you to do this
- 8:21Speaker 1: at such an efficient scale? Were you more disciplined? Did
- 8:24Speaker 1: you watch cash flow? Did you feel like your belts
- 8:28Speaker 1: were tight or were you just being more efficient leveraging
- 8:32Speaker 1: AI and ML?
- 8:34Speaker 2: Yeah, well, it's a combination of both. We were very
- 8:38Speaker 2: careful to build a community that knew, here's a key
- 8:43Speaker 2: point in the history of the company. This is going
- 8:45Speaker 2: to be a make or break it. We can't really
- 8:47Speaker 2: pay these exorbitant salaries. We've got to be very lean
- 8:50Speaker 2: on how we investigate programs. So we really adopted a
- 8:54Speaker 2: fast to fail where we make some compounds, we test
- 8:57Speaker 2: some biology and And maybe it looks okay, but it's
- 9:01Speaker 2: not extraordinary. And we just wind the program down. We're
- 9:05Speaker 2: really looking for those resilient programs that we could build
- 9:07Speaker 2: a lot of evidence around when we're trying to figure
- 9:10Speaker 2: out the translational direction that we needed to go. Things
- 9:13Speaker 2: that just kept on sticking. And what I mean by that,
- 9:15Speaker 2: we kept on getting good animal work. When we would
- 9:18Speaker 2: go into candidate nomination studies, we kept on finding exciting
- 9:21Speaker 2: profiles for those molecules. As they're just being very disciplined
- 9:24Speaker 2: in terms of we're going to cast a lot of netts.
- 9:27Speaker 2: but we're really only going to bear down on the
- 9:29Speaker 2: net that just is bountiful. Like we keep on pulling
- 9:32Speaker 2: up a feast from the ocean. And that's, that's been
- 9:34Speaker 2: the rock story for us. And just making sure that
- 9:36Speaker 2: we were lean, we were efficient. We didn't have a
- 9:39Speaker 2: lot of bloat on the, on the staff side. We
- 9:43Speaker 2: really only hired people that filled the key deficiency in
- 9:45Speaker 2: the company. Uh, so things like regulatory, uh, translational pharmacology, uh,
- 9:51Speaker 2: all the chemistry that you need in order to work
- 9:53Speaker 2: on small molecules. in terms of CMC and the regulatory
- 9:57Speaker 2: side of things. And so that's what's been able on
- 10:02Speaker 2: the strategy side for us to really move the needle here.
- 10:05Speaker 2: On the technology side, what we do is something very
- 10:08Speaker 2: different from a lot of machine learning and AI out there.
- 10:12Speaker 2: In fact, when we were originally starting the company, Everybody
- 10:15Speaker 2: was telling us, oh, you're overfitting, right? And that's the
- 10:18Speaker 2: worst thing that you could do in machine learning. It's
- 10:22Speaker 2: heresy to use very small data sets and say, no,
- 10:25Speaker 2: we're going to have better generalization than these ultra large
- 10:28Speaker 2: libraries looking at the universe of chemical space. And now
- 10:33Speaker 2: we've got some, we published a paper on this earlier
- 10:36Speaker 2: this year, but we've been wrestling with bringing in causality
- 10:40Speaker 2: into machine learning. Causality is this discipline of how do
- 10:44Speaker 2: we mathematically describe cause and effect, okay? And so let's
- 10:47Speaker 2: say I have some data set for a target of interest. Oftentimes,
- 10:53Speaker 2: I actually have a bunch of different submechanisms in that set.
- 10:56Speaker 2: And from a chemistry and pharmacology perspective, it doesn't make
- 10:59Speaker 2: any sense to treat those as if they're mutually informative.
- 11:02Speaker 2: But the machine learning community would because it was the target, right?
- 11:06Speaker 2: And so you build these very, very large models, and
- 11:10Speaker 2: they'd have a good general sense of affinity and potency,
- 11:14Speaker 2: but they would lose, every time we tested it on subscaffolds,
- 11:17Speaker 2: we would lose the specific details. So it'd be very
- 11:21Speaker 2: good at the general, but very bad at the specific.
- 11:23Speaker 2: And so what we found is that actually if we
- 11:26Speaker 2: focused in, and focus is a concept that we created
- 11:30Speaker 2: to describe the balance between fitness and mechanistic resolution or focus,
- 11:35Speaker 2: if we focused in on the scaffold, we could become
- 11:38Speaker 2: very powerful on that scaffold and basically ignore everything else.
- 11:43Speaker 2: And this is very important if you're going to do
- 11:46Speaker 2: candidate design, because oftentimes when you've got some cell-based talks
- 11:50Speaker 2: or some cell-based off-target pharmacology that you have to model,
- 11:54Speaker 2: there are 10, 20, 30, who knows how many mechanisms
- 11:57Speaker 2: in that data set and they're hidden and you can't
- 11:59Speaker 2: pull them out easily. And so we were able to
- 12:00Speaker 2: step in, focus in on that mechanism for that space,
- 12:04Speaker 2: build four or five algorithms that can optimize the space
- 12:07Speaker 2: And we made 11 compounds to find two clinical candidates.
- 12:10Speaker 2: So that's extraordinary, right? That level of efficiency hasn't been
- 12:15Speaker 2: obtained by any other group outside of Avicenna. Normally, you
- 12:18Speaker 2: have to make hundreds of molecules, thousands of molecules to
- 12:21Speaker 2: find a clinical candidate. We made 11 to find two.
- 12:25Speaker 2: And we did it again in CSF1R.
- 12:28Speaker 1: From the layman's perspective, I want to say this back
- 12:30Speaker 1: to you and see if the analogy I'm drawing is right.
- 12:34Speaker 2: The.
- 12:36Speaker 1: Proverbial wisdom would be with you take the broadest possible
- 12:40Speaker 1: data set, you zoom out as much as possible, and
- 12:43Speaker 1: you let the AI go to work. That's using the
- 12:48Speaker 1: biggest possible data set. And what you're saying is you
- 12:51Speaker 1: took a rifle shot more approach and said there's too
- 12:55Speaker 1: much noise in all this data. I'm actually going to
- 12:58Speaker 1: zoom in. And that's where this is the heresy you're
- 13:01Speaker 1: referring to that actually said, by zooming in on what
- 13:05Speaker 1: I really want to be intentional about and putting the
- 13:08Speaker 1: ML and the algorithm to work, I've actually cut out
- 13:11Speaker 1: of a lot of noise. And that's why I'm getting
- 13:12Speaker 1: two candidates out of 11 design.
- 13:16Speaker 3: Like, is that a fair way to say it back
- 13:18Speaker 3: to you?
- 13:19Speaker 2: That's exactly right. And being able to inferentially zoom in
- 13:24Speaker 2: on the mechanism, that's why we call it inferential mechanics.
- 13:27Speaker 2: That's the really exciting thing is it gives us a
- 13:29Speaker 2: new mathematical framework to navigate the mechanistic landscape in the
- 13:33Speaker 2: natural sciences. And that's really cool from a philosophical perspective.
- 13:38Speaker 2: But in terms of drug design, when you build these
- 13:41Speaker 2: very general, very nonspecific algorithms, they're actually really weak on
- 13:45Speaker 2: a case-by-case-by-case basis. You can think of it as like
- 13:48Speaker 2: I've got a pink series that I want to model.
- 13:51Speaker 2: And then I've got red, orange, yellow, green, blue, purple
- 13:54Speaker 2: in my data set. If I lump them all together,
- 13:56Speaker 2: the average color of that is brown, right? Brown doesn't
- 13:59Speaker 2: actually exist in my data set. Brown is an artificial
- 14:02Speaker 2: color that's the average of all of these. And so
- 14:04Speaker 2: I build this brown algorithm, and when I test train,
- 14:06Speaker 2: I keep on getting brown because I'm mixing all of
- 14:08Speaker 2: these colors. But when I go and make a prediction
- 14:11Speaker 2: in the pink space, the red space, the blue space,
- 14:13Speaker 2: it doesn't work. when I test just in those regions
- 14:17Speaker 2: rather than as an average, then that's the issue.
- 14:20Speaker 3: That's so well put.
- 14:21Speaker 1: And it is, it's really cool to have you on
- 14:23Speaker 1: the show because this is groundbreaking stuff between your paper.
- 14:26Speaker 1: We'll get to your op-ed in a second, but you
- 14:29Speaker 1: did something different. And in gosh, not five years, but
- 14:33Speaker 1: in five months, people are going to be trying to
- 14:34Speaker 1: replicate what Avicenna has done and say, maybe we are
- 14:38Speaker 1: thinking about this wrong. So you are the right guy
- 14:39Speaker 1: for the right moment, because as we speak, as we're recording, um,
- 14:44Speaker 1: folks are gathering in Washington to talk about AI and
- 14:47Speaker 1: we'll see how much biotech comes up. I don't think
- 14:49Speaker 1: it'll come up much, but you penned an incredible piece
- 14:53Speaker 1: that is linked to in the comments and the description.
- 14:56Speaker 1: So people, please, if you're interested in how AI is
- 15:00Speaker 1: reshaping this industry, it is the right piece to read.
- 15:03Speaker 1: And in it, you say that AI will change drug
- 15:07Speaker 1: design development, but quote, not in the ways widely being presented.
- 15:12Speaker 3: Can you spell that out here?
- 15:14Speaker 1: What are folks getting wrong with their assumptions of how
- 15:18Speaker 1: AI is going to be transformative?
- 15:20Speaker 2: I mean, you see it just over and over, even
- 15:22Speaker 2: beyond biotech, just the sensationalism is everywhere. And I think
- 15:27Speaker 2: that's a lot. That's the point. Number one is we
- 15:30Speaker 2: just kind of dial down the sensationalism. A lot of
- 15:32Speaker 2: people will actually, a very small number of people stand
- 15:35Speaker 2: to make a lot of money off of these sensational claims.
- 15:38Speaker 2: And we should be perhaps most skeptical around that group.
- 15:41Speaker 2: But In terms of AI and what we're doing in
- 15:45Speaker 2: the natural sciences and the clinical sciences, they draw on
- 15:49Speaker 2: these knowledge graphs, like these very large frontier models, foundation
- 15:53Speaker 2: models that underpin large language models like ChatGPT or CLOD.
- 16:00Speaker 2: They go into the literature and you can basically generate
- 16:04Speaker 2: these knowledge graphs around literature teachings and abstracts and then
- 16:09Speaker 2: full bodies of papers. Sadly, the fundamental issue, or at
- 16:13Speaker 2: least one of the fundamental issues, is that a lot
- 16:15Speaker 2: of the data that underpin the literature is irreproducible. And
- 16:20Speaker 2: we've known about this for about 20 years in the
- 16:22Speaker 2: natural sciences. And it's been a big issue, especially in
- 16:25Speaker 2: more applied sciences like psychology, where straight up you just
- 16:29Speaker 2: can't reproduce the findings of the paper. And so... That's
- 16:33Speaker 2: a major issue if you treat that as if it's
- 16:36Speaker 2: true knowledge and you start learning trends from a knowledge
- 16:40Speaker 2: graph across all of these irreproducible results. Well, you're going
- 16:44Speaker 2: to learn things that aren't actually real, right? And in
- 16:49Speaker 2: terms of biotech, a great example of this is the
- 16:51Speaker 2: beta amyloid story. It turns out, I think this was
- 16:54Speaker 2: now three or four years ago, a lot of the
- 16:57Speaker 2: original beta amyloid work linking beta amyloid pathology to Alzheimer's
- 17:03Speaker 2: was just completely fabricated. And so this has been a
- 17:06Speaker 2: major problem for Alzheimer's research because one of the core
- 17:10Speaker 2: bedrocks of the discipline now is no better than sand.
- 17:15Speaker 2: We can't build on this foundation. And that's just one
- 17:18Speaker 2: example of many, many, many examples where You go in
- 17:21Speaker 2: and you try and replicate something and it's just, it's
- 17:24Speaker 2: not even wrong, right? It's nowhere close to even being
- 17:27Speaker 2: sort of kind of incorrect. It's just completely irreproducible in noise.
- 17:32Speaker 2: That's a lot of what is being touted right now
- 17:36Speaker 2: in AI is the ability to sift through the literature,
- 17:38Speaker 2: be able to sift through internal data sets and find
- 17:40Speaker 2: novel biological connections. And we just aren't at the level
- 17:44Speaker 2: of resiliency and redundancy in our literature in order for
- 17:48Speaker 2: that to truly be a revolution, to be transformative. So
- 17:52Speaker 2: that's point number one. Point number two is that drug design,
- 17:59Speaker 2: especially if you're dealing with new biology and new chemistry,
- 18:03Speaker 2: you don't know what's going to work until you're on
- 18:05Speaker 2: the other side of a new drug application, right? So
- 18:10Speaker 2: that's the problem is there's a 10-year lag between, wow,
- 18:13Speaker 2: this looks really cool and maybe we should invest some
- 18:15Speaker 2: time and and resources in this to actually becoming a drug.
- 18:19Speaker 2: And even then you go to phase four, right? Drugs
- 18:21Speaker 2: come off market because they aren't actually working, right? So
- 18:25Speaker 2: that's the other problem is the cycle for knowledge in
- 18:29Speaker 2: translational pharmacology, clinical pharmacology is only order of a decade.
- 18:34Speaker 2: And all of these, I've had so many ideas in
- 18:39Speaker 2: Avicenna with my colleagues that, man, this looks really cool.
- 18:42Speaker 2: And then we go and actually dive into it and
- 18:45Speaker 2: look at the translational pharmacology and it turns out it's
- 18:47Speaker 2: just completely wrong. Good ideas are cheap. Durable ideas are
- 18:52Speaker 2: the hard part. And AI can't help you there.
- 18:54Speaker 1: That– well, I think I know what tagline the production
- 18:57Speaker 1: team is going to pull. Those good ideas– I want
- 19:01Speaker 1: to stay on this for one second because I want
- 19:03Speaker 1: to make sure listeners are picking this up. I think
- 19:08Speaker 1: there is a belief that we can set AI loose
- 19:13Speaker 1: on the last century of academic literature, basic research, NIH,
- 19:18Speaker 1: all the way up to true drug discovery, and it's
- 19:22Speaker 1: going to just find things that we missed. I think
- 19:25Speaker 1: your piece and what you just said is calling out
- 19:28Speaker 1: something that we don't like to talk about, that there
- 19:31Speaker 1: are some real problems in the data sets going back
- 19:34Speaker 1: the last few decades, and they're not reproducible, and if
- 19:38Speaker 1: you're training your AI on things that aren't borne out
- 19:42Speaker 1: in actual fact.
- 19:43Speaker 3: And so is part of what we have.
- 19:46Speaker 1: To do to really maximize this, and you do some
- 19:49Speaker 1: math that I want you to get into. I think
- 19:52Speaker 1: delivering 100 years of new drugs in the next 10,
- 19:57Speaker 1: I think is a big claim. And you kind of
- 20:01Speaker 1: take it to task in your piece. I want you
- 20:03Speaker 1: to unpack that. but is also part of this. We've
- 20:07Speaker 1: got to clean up a lot of the last 20,
- 20:10Speaker 1: 30 years of science and these assumptions. And we've got
- 20:13Speaker 1: to get serious. And this goes back to your rifle shot.
- 20:17Speaker 1: We've got to be serious about what we're putting in,
- 20:19Speaker 1: not building on a foundation of sand. We've got to
- 20:21Speaker 1: build on a foundation of stone. And right now, how
- 20:26Speaker 1: do we get that confidence level up that what we
- 20:29Speaker 1: took as fact for the last 20 years is actually fact?
- 20:33Speaker 2: Well, and I want to extend it just a little bit.
- 20:35Speaker 2: Like even good papers, good science can go on and
- 20:40Speaker 2: people find out actually there were hidden things all along
- 20:43Speaker 2: that were driving that conclusion. And that's the issue is
- 20:47Speaker 2: like there are really, really extraordinary stories. Like I'll give
- 20:51Speaker 2: you an example rather than speaking in platitudes. But so
- 20:54Speaker 2: there's this chemistry in this. I apologize if you're not
- 20:57Speaker 2: a chemist, going to nerd out a little bit, but
- 20:59Speaker 2: there's a reaction called the Nozaki-Hiyama-Kishi reaction. And it came
- 21:04Speaker 2: around in the 70s. And it was this really cool
- 21:08Speaker 2: way to couple vinyl halides with carbonyls in one pot. Normally,
- 21:14Speaker 2: this is really hard. You have to use some very
- 21:16Speaker 2: dangerous chemistry in order to do this. But people found
- 21:19Speaker 2: that there was this chromium-mediated reaction that could facilitate this coupling.
- 21:25Speaker 2: And lo and behold, people tried to replicate it. And
- 21:28Speaker 2: they couldn't. They were using the same chromium reagent, same substrates,
- 21:32Speaker 2: couldn't get the reaction to work. And it turns out
- 21:35Speaker 2: the original chromium samples that were being used for this
- 21:38Speaker 2: were contaminated by nickel. It was actually a chromium-mediated nickel-catalyzed reaction.
- 21:44Speaker 2: And so the moment this other group put nickel into
- 21:47Speaker 2: their reaction, the Nozaki-Hiyama-Kishi reaction would work. No nefariousness, no sloppiness,
- 21:53Speaker 2: just a trace impurity in a chromium sample was the
- 21:57Speaker 2: serendipity behind that discovery. And that story is very common, right?
- 22:01Speaker 2: The thing that you become comfortable with, comfortable is perhaps
- 22:05Speaker 2: not the right word, but the thing that you become
- 22:08Speaker 2: familiar with in the natural sciences is how little we
- 22:12Speaker 2: know about nature and how complex the universe is. And
- 22:17Speaker 2: it's a rare thing when you truly can find some
- 22:20Speaker 2: new knowledge that's durable. And even when you do everything right,
- 22:24Speaker 2: and you're very careful, considerate, and deliberate there's still a
- 22:27Speaker 2: massive role of serendipity in discovering. There always will be
- 22:32Speaker 2: because the universe is just that complex. And so that's
- 22:34Speaker 2: the thing that the computer scientists don't fully understand is
- 22:39Speaker 2: just the stupefying amount of complexity in chemistry, biology, and physics.
- 22:44Speaker 2: And that's something that chemists, biologists, and physicists understand very,
- 22:47Speaker 2: very clearly. So unless you're working in well-established domains where
- 22:52Speaker 2: there's a lot of reproducibility, and you know all of
- 22:55Speaker 2: the unknowns more or less, I really can't help you
- 22:58Speaker 2: because the universe is just that unknown, right? I mean,
- 23:02Speaker 2: you know, I'm gesticulating with my hand. Think about how
- 23:04Speaker 2: many Nobel prizes are going on in my hand and
- 23:06Speaker 2: I just use it routinely to make gestures. All of
- 23:09Speaker 2: those aspects of biology are still important for the day-to-day
- 23:12Speaker 2: functioning of my hand and its physiology. We don't know
- 23:16Speaker 2: about those aspects. They're just in the background, right? And
- 23:20Speaker 2: that's the hard part is how do I design artificially
- 23:24Speaker 2: intelligent systems, pattern recognition systems, machine learning agents. How do
- 23:28Speaker 2: I design those things to be able to find design
- 23:33Speaker 2: goals or new knowledge in that background of uncertainty and
- 23:37Speaker 2: irreproducibility and serendipity? That's the hard part.
- 23:41Speaker 1: This is definitely going to be an episode of humility
- 23:43Speaker 1: because I think you're laying it out.
- 23:45Speaker 3: There's so much we don't know.
- 23:47Speaker 1: And if something AI does well is it manipulates what
- 23:51Speaker 1: we know for certain allows us to apply it in
- 23:54Speaker 1: new ways. But if we're not certain about what we know,
- 23:57Speaker 1: there are some limitations, which comes up with, what do
- 23:59Speaker 1: you make of the claim that we're going to do
- 24:01Speaker 1: 100 years of biotech in the next 10 years?
- 24:05Speaker 2: Yeah, it's sensationalist, right? That's the word of the day
- 24:13Speaker 2: for a lot of these these AI companies is they're
- 24:16Speaker 2: making these sensational claims and it's catching a lot of
- 24:18Speaker 2: attention and it sounds cool and people want it to
- 24:21Speaker 2: be cool. So they're raising huge piles of money, but
- 24:24Speaker 2: it's just not going to be durable. And that's the,
- 24:27Speaker 2: the issue is we would have to discover, depending upon
- 24:31Speaker 2: your estimate, how you run the arithmetic between 450, 550
- 24:34Speaker 2: new drugs every year in order for that to be true.
- 24:36Speaker 2: And what, That's just an unfathomable amount of drug development work.
- 24:49Speaker 2: If we run the capital requirements of that, you and
- 24:51Speaker 2: I had a conversation via email with Grace, and I
- 24:55Speaker 2: think John Guy asked the question, so you think you're
- 25:00Speaker 2: going to saturate the regulatory environment? No, we're going to
- 25:04Speaker 2: saturate the capital markets before that, right? 500-some-odd drugs is
- 25:09Speaker 2: a lot of money, right? There's no way we have
- 25:11Speaker 2: enough money around to develop those, let alone the scientific
- 25:14Speaker 2: know-how to do that at that scale. It's just an
- 25:17Speaker 2: absurd number.
- 25:19Speaker 3: It's such a good call.
- 25:21Speaker 1: I mean, you see the numbers around CapEx on data
- 25:24Speaker 1: centers and AI, and you think the pot is limitless.
- 25:27Speaker 1: And if you have a good idea, the capital is
- 25:30Speaker 1: going to be there. And you make the point, we're
- 25:32Speaker 1: not going to 10x VC overnight. We're not going to
- 25:34Speaker 1: go from $ 40 billion to $ 400 billion overnight. That's ludicrous,
- 25:40Speaker 1: let alone– I love– our policy director, John Guy, asks
- 25:43Speaker 1: the best questions. Is the regulatory ecosystem prepared for 10x
- 25:48Speaker 1: the number of submissions? And I think you make the
- 25:51Speaker 1: good point that we'll be capitals constrained before we're regulatorily constrained.
- 25:56Speaker 1: So that's– so there are nuances. It's not– AI is
- 26:00Speaker 1: not going to be the easy button. But let's close
- 26:03Speaker 1: out AI on a positive note. Where do you see
- 26:06Speaker 1: it helping and where do you see it being transformative?
- 26:09Speaker 2: Yes. So two areas. One that is within Avicenna's remit
- 26:13Speaker 2: is clinical candidate design. If you have a very good
- 26:17Speaker 2: idea of your biology, your translational pharmacology, and you just
- 26:20Speaker 2: need to put all the pieces together on your medicinal chemistry,
- 26:23Speaker 2: AI is very powerful there, right? We've demonstrated this. It's
- 26:27Speaker 2: transformative tools. because it can solve that multi-objective optimization problem
- 26:31Speaker 2: for you very efficiently, if and only if you know
- 26:35Speaker 2: what your target product profile is, right? And you know
- 26:39Speaker 2: more or less how you can massage the chemistry in
- 26:41Speaker 2: order to match up with that. The other area that
- 26:44Speaker 2: I think is really exciting is being able to sift
- 26:47Speaker 2: through electronic health records and find either repurposing, repositioning opportunities
- 26:54Speaker 2: where we can redesign new candidates, be they small molecule
- 26:58Speaker 2: or biologic. And then also finding associations between diseases and
- 27:05Speaker 2: serological markers and maybe gleaning some new pathology and some
- 27:09Speaker 2: new disease biology there. There's a lot of work there
- 27:13Speaker 2: because you want to talk about noisy data sets for
- 27:16Speaker 2: training and learning. Electronic health records are very noisy and
- 27:19Speaker 2: they're often very fragmented and it's going to be a
- 27:22Speaker 2: big lift to get them ready for machine learning. But
- 27:26Speaker 2: already you're seeing groups learning, hey, I've got some clinicians
- 27:31Speaker 2: that have been reusing this drug off-label for this indication
- 27:34Speaker 2: that we thought was completely unrelated, and it's been working.
- 27:37Speaker 2: How do we design a drug to go after that
- 27:38Speaker 2: indication and that target? Maybe there's some new pharmacology there
- 27:43Speaker 2: for us to work on. So that, I think, is
- 27:46Speaker 2: when you can constrain the context and you can ask
- 27:51Speaker 2: very deliberate questions about pharmacology pathology, And clinical trial design.
- 27:59Speaker 2: I think AI is going to be very powerful. But
- 28:01Speaker 2: you have to be very deliberate about asking your question.
- 28:05Speaker 2: And you have to make sure that the context underneath
- 28:08Speaker 2: your feet isn't sifting unwittingly. That's where AI becomes very bad.
- 28:12Speaker 2: If the contextual rules change and you don't know they've changed,
- 28:16Speaker 2: then AI is no better than guessing.
- 28:20Speaker 1: This has been the bee in my bonnet about this
- 28:23Speaker 1: because I think of this also in a globally competitive standpoint.
- 28:27Speaker 1: I am concerned– so you tell me whether this is
- 28:30Speaker 1: a worry you share– that our fragmented data sets held
- 28:35Speaker 1: by hospitals, held by insurers, the EHR revolution didn't really
- 28:41Speaker 1: materialize I think the way we thought it might. Our data,
- 28:46Speaker 1: patient data– failed clinical trials, they all sit at different
- 28:51Speaker 1: entities that'll have different ways most likely to monetize that data.
- 28:58Speaker 1: I had an interesting conversation with some of the leadership
- 29:00Speaker 1: in the UK on their drug development side. They have
- 29:04Speaker 1: centralized data. They can just tap into the NHS. You know,
- 29:08Speaker 1: people look to where does Australia get an advantage? Where
- 29:11Speaker 1: does Germany get an advantage? Where does China get an advantage?
- 29:14Speaker 1: That's certainly the number one topic. Are you concerned that
- 29:20Speaker 1: the entities that hold our data here, especially on the
- 29:24Speaker 1: insurer side and the hospital side, will make it too
- 29:27Speaker 1: difficult or too slow to aggregate that fragmented data in
- 29:30Speaker 1: a way that we're competitive vis-a-vis the NHS?
- 29:34Speaker 2: Oh, yeah. So I went to Oxford for medical school
- 29:39Speaker 2: and earned my license to practice. in the UK. And
- 29:42Speaker 2: that training under a single-payer healthcare system opened my eyes
- 29:47Speaker 2: to a lot of things that we are doing not
- 29:49Speaker 2: quite right in the US. But I was just up
- 29:52Speaker 2: in Canada at the Gardner Lecture for AI and Healthcare,
- 29:56Speaker 2: and And I gave a talk on influential mechanics and
- 30:00Speaker 2: what Avacyn is doing. But the thing that really caught
- 30:02Speaker 2: my ear is how the province of Alberta and Canada
- 30:05Speaker 2: in general are thinking about electronic health records. It's centralized.
- 30:09Speaker 2: They're making it accessible where there's one regulatory process for
- 30:14Speaker 2: accessing that. They're very careful about patient safety and patient privacy.
- 30:18Speaker 2: But beyond that, there's a centralized portal to access all
- 30:22Speaker 2: of this information. And it's interesting to me that the
- 30:24Speaker 2: thought that I had was, Wouldn't it be ironic if
- 30:29Speaker 2: data monetization was the thing that pushed the U.S. to
- 30:31Speaker 2: a national healthcare system? Like, we've got all this private data.
- 30:35Speaker 2: We've got to make some money off of it, so
- 30:36Speaker 2: let's have a single-payer system. That would be ironic. But, yeah,
- 30:42Speaker 2: I think you're exactly right. The frontier for discovery in
- 30:47Speaker 2: terms of new drive opportunities, new targets... new ways of
- 30:52Speaker 2: doing patient recruitment or adaptive clinical trial design, especially with
- 30:56Speaker 2: AI where you're feeding the information, serological markers, and you're
- 31:00Speaker 2: literally adapting the trial as you run it to the
- 31:02Speaker 2: response of patients. That's going to require a very savvy
- 31:07Speaker 2: and sophisticated EHR processing system. And those national healthcare systems
- 31:13Speaker 2: that have unified single point of access EHRs, are going
- 31:18Speaker 2: to beat us because our system is so fragmented. Like
- 31:20Speaker 2: if I want to go down the street, let's say
- 31:22Speaker 2: I want to go to Medical University South Carolina, I
- 31:25Speaker 2: have to go and interact with a very different framework
- 31:28Speaker 2: than I would if I want to go down the
- 31:31Speaker 2: street in Durham to Duke or to UNC Chapel Hill.
- 31:36Speaker 2: And that's just three universities within a relatively small geographic
- 31:39Speaker 2: region of the United States. It's a nightmare to access
- 31:43Speaker 2: large-scale patient repositories compared to what Britain has to offer
- 31:47Speaker 2: or what Canada is building. Mark Carney was up on
- 31:49Speaker 2: the stage when they were rolling out the Canada initiative
- 31:53Speaker 2: for AI. First and foremost, it was healthcare. And it
- 31:56Speaker 2: was around building AI for all in healthcare. And so
- 32:00Speaker 2: that's a major initiative in Canada right now is to
- 32:04Speaker 2: really take advantage of the national advantage that they have
- 32:07Speaker 2: in terms of EHR and other similar things and lead
- 32:11Speaker 2: the way for AI in healthcare, be it AI scribing,
- 32:15Speaker 2: AI in adaptive clinical trial design, et cetera. And we
- 32:19Speaker 2: just don't have the infrastructure on the informatics side in
- 32:22Speaker 2: the US to compete with that right now.
- 32:26Speaker 1: When you have a genus on the show, you throw
- 32:28Speaker 1: out as many questions as you can.
- 32:30Speaker 3: Okay.
- 32:31Speaker 1: Is the data abroad good enough for someone like yourself
- 32:38Speaker 1: to go ping it there? Or do we need to
- 32:41Speaker 1: build this here in the U.S.
- 32:43Speaker 2: Yeah, so the answer is both, and it really does depend.
- 32:49Speaker 2: The interesting thing about, like, if you've got very rare
- 32:53Speaker 2: diseases with a very uniform genetic background, the data abroad
- 32:57Speaker 2: are probably going to be very useful for us. Like,
- 33:01Speaker 2: von Lippenau mutations are going to behave the same largely
- 33:05Speaker 2: in Britain versus in the US. But one of the
- 33:10Speaker 2: interesting things that we've seen, and this kind of goes
- 33:13Speaker 2: to Japanese regulatory policy, is sometimes drugs behave in populations
- 33:17Speaker 2: very differently than other populations at a national scale. In fact,
- 33:20Speaker 2: Japan insists that a drug be tested on Japanese people
- 33:24Speaker 2: in order to get regulatory approval in Japan. And that's
- 33:26Speaker 2: because the genetic background shifts, the cultural background shifts, the food,
- 33:30Speaker 2: the exercise habits shift. So there's a lot of extra
- 33:34Speaker 2: stuff that goes into the background of a drug working,
- 33:38Speaker 2: that sometimes if you shift nation by nation by nation,
- 33:41Speaker 2: you see different response rates for drugs that work via
- 33:46Speaker 2: multiple insults or multiple genetic backgrounds that give rise to
- 33:50Speaker 2: that disease. So it really depends. For single mutation rare diseases,
- 33:58Speaker 2: I think that a national agnostic data set will be
- 34:02Speaker 2: very useful. But for things like metabolic syndrome, general colon
- 34:08Speaker 2: cancer risk, inflammatory immunology indications that have a lot of
- 34:13Speaker 2: different reasons for the disease appearing. Those are still going
- 34:18Speaker 2: to require a national level system in order to be
- 34:21Speaker 2: able to address those diseases on the terms of the
- 34:23Speaker 2: United States.
- 34:24Speaker 1: To say that back to you another way, the more
- 34:26Speaker 1: environmental factors might play a role in a disease, we're
- 34:30Speaker 1: going to want to have a U.S.
- 34:31Speaker 3: Data set. And I think that ties.
- 34:33Speaker 1: Very much into the Maha, what we eat, our food
- 34:36Speaker 1: ecosystem is different here. And so things that are modified
- 34:40Speaker 1: by what you surround yourself with. That's where we're going
- 34:43Speaker 1: to wish we had a U.S. population data set.
- 34:45Speaker 2: Exactly so.
- 34:46Speaker 3: Super, super helpful.
- 34:47Speaker 1: You mentioned Japan, and it's actually very timely, one, because
- 34:51Speaker 1: Making Medicine will be on the road in Japan in
- 34:54Speaker 1: a week's time. But while we're there, we're going to
- 34:57Speaker 1: be talking to a lot of their national leaders who
- 35:00Speaker 1: continue to ask why they have drug lag and drug
- 35:03Speaker 1: loss over there. And you point to their regulatory system.
- 35:08Speaker 1: I think we're optimistic that they're also going to start
- 35:10Speaker 1: valuing medicine in a more robust manner when it demonstrates
- 35:16Speaker 1: that it does have that value for the Japanese population.
- 35:20Speaker 1: When you balance– putting on your investor hat, when you
- 35:23Speaker 1: balance something like that, is it both the pricing and
- 35:28Speaker 1: reimbursement as well as the regulatory system or do they
- 35:33Speaker 1: need to pull both levers? Make it easier to get
- 35:35Speaker 1: a drug approved in the market. but you also have
- 35:38Speaker 1: to fairly value and reimburse it.
- 35:40Speaker 2: I think short answer, yes. And there's a third thing.
- 35:43Speaker 2: The venture ecosystem in Japan is very small. So like
- 35:47Speaker 2: a big Series B is $ 6 million. So it makes
- 35:52Speaker 2: it very difficult to actually bring drugs to market that
- 35:56Speaker 2: are fully incubated in Japan in the biotech sector. Don't
- 35:59Speaker 2: get me wrong, Takeda and Otsuka and others, they're very
- 36:03Speaker 2: good at large-scale traditional pharma drug design development. But the
- 36:09Speaker 2: biotech ecosystem in Japan is still quite small. Regulatory path
- 36:13Speaker 2: to approval is a major issue and then absolutely reimbursement.
- 36:17Speaker 2: People aren't going to invest in your drug program if
- 36:19Speaker 2: they think, well, payers aren't going to pay. So that's
- 36:23Speaker 2: a major issue for ultra-rare indications is how do we
- 36:26Speaker 2: make sure that they're investable because there are areas of
- 36:29Speaker 2: huge need that are still poorly served. But I think
- 36:33Speaker 2: it's a constellation of all three, that the biotech ecosystem
- 36:36Speaker 2: is still fairly small, especially on the investment side. It's
- 36:38Speaker 2: difficult to get regulatory approval in Japan. And you've got
- 36:42Speaker 2: to make sure that there is appropriate remuneration for that
- 36:45Speaker 2: investment risk.
- 36:46Speaker 1: I'm going to keep throwing them at you. We're going
- 36:48Speaker 1: to take full advantage of the time you've given us.
- 36:50Speaker 1: Let's move a little south in the Pacific down to China.
- 36:53Speaker 1: Hot topic about how Chinese rise in the biotech space
- 37:00Speaker 1: is transformative. And we certainly have pockets of protectionism within
- 37:05Speaker 1: our own industry. We've got what's treasury going to do
- 37:07Speaker 1: with coins.
- 37:08Speaker 3: We've got, is.
- 37:09Speaker 1: Congress going to do more? How do you, someone who
- 37:13Speaker 1: both sits on the founder side, now the investment side,
- 37:17Speaker 1: you're one of the big minds in AI. How do
- 37:20Speaker 1: you think about China in the global drug development landscape?
- 37:24Speaker 2: Yeah, we've been training Chinese scientists in the United States
- 37:27Speaker 2: and the West in general for 50 years. So it's
- 37:30Speaker 2: not surprising to me that talented people are now going
- 37:34Speaker 2: to go back to their country and start competing with
- 37:38Speaker 2: us on our terms. The Chinese are extraordinarily talented at
- 37:44Speaker 2: small molecule chemistry, organic synthesis, organometallics. So it's only natural
- 37:49Speaker 2: that I think they'll lean into those industries, especially when
- 37:52Speaker 2: they're backed by the Chinese government. One of the things
- 37:56Speaker 2: that I still think we do better than they do
- 38:00Speaker 2: is completely new targets, optimization, and then translational pharmacology. So
- 38:07Speaker 2: we still have a huge biological innovation competitive advantage here.
- 38:11Speaker 2: And there's a lot of risks there, as I alluded
- 38:13Speaker 2: to earlier. But when you do find new targets that
- 38:16Speaker 2: can translate... that's really where we can keep a significant
- 38:21Speaker 2: competitive edge. And then also, I think going after rare
- 38:26Speaker 2: diseases is something that the U.S. will retain a competitive
- 38:30Speaker 2: edge in because those clinical trials are often very atypical.
- 38:34Speaker 2: They require a lot of expertise to plan, especially for
- 38:37Speaker 2: rare CNS indications. There's often two acronyms, PK and PD,
- 38:45Speaker 2: pharmacokinetics and pharmacodynamics. The PKPD linkage in CNS is very
- 38:51Speaker 2: hard to address because you're modulating targets deep in the brain.
- 38:55Speaker 2: Often they're intracellular. And so you have to be very,
- 38:58Speaker 2: very good about addressing that PKPD response and overlap as
- 39:04Speaker 2: part of your translational pharmacology package. And that still requires
- 39:07Speaker 2: a lot of expertise that industry in the US still
- 39:10Speaker 2: has compared to China.
- 39:12Speaker 1: Something when I sit with leaders in the rare disease
- 39:14Speaker 1: community and hear about their priorities, The IITs in China,
- 39:22Speaker 1: which China is through their 818 process beginning to corral,
- 39:27Speaker 1: I would say, some of these more out there IITs. Obviously,
- 39:31Speaker 1: we kind of have started to see some tragic stories
- 39:34Speaker 1: coming out of China where clinical trial design may have
- 39:38Speaker 1: played a role from safety. But then I also hear
- 39:41Speaker 1: from rare disease advocates that they could only move an
- 39:45Speaker 1: asset forward because of the low cost of these investor
- 39:50Speaker 1: investigator initiated trials. How do you think about IITs in China? Um,
- 39:56Speaker 1: because it seems very nuanced. There are some benefits of
- 39:59Speaker 1: moving something forward very cheaply. Um, but there are also
- 40:02Speaker 1: probably some drawbacks that these trials wouldn't be allowed to
- 40:06Speaker 1: be stood up or they wouldn't be stood up in
- 40:08Speaker 1: similar ways in the U S.
- 40:10Speaker 2: Yeah, I completely agree. I mean, I, I think the
- 40:14Speaker 2: fact that so many, even investors that are making a
- 40:19Speaker 2: big China play, they still want to repeat these pivotal
- 40:22Speaker 2: trials in the U.S. under U.S. supervision tells you a
- 40:25Speaker 2: lot about how much confidence even Western investors that are
- 40:32Speaker 2: in the China hypothesis, how much confidence they have in
- 40:35Speaker 2: the data that come out of those trials. You really
- 40:37Speaker 2: want to make sure that under very rigorous, highly controlled terms,
- 40:41Speaker 2: The pharmacology that you see is the pharmacology that was
- 40:44Speaker 2: seen in China. And I think there's a risk there
- 40:49Speaker 2: that you can go too fast, too quickly with addressing
- 40:52Speaker 2: all of your confounders, going back to causality. That was
- 40:56Speaker 2: one of the early areas of bringing causality into the
- 41:01Speaker 2: sciences was actually clinical trials and clinical data and addressing
- 41:04Speaker 2: these confounders. If you go too quickly, oftentimes you can
- 41:07Speaker 2: have confounders that come along for the ride or, as
- 41:10Speaker 2: you were talking about, there are big safety issues where
- 41:12Speaker 2: you didn't appropriately recruit. You allowed people to come in
- 41:16Speaker 2: who were actually fairly high risk to your target modification
- 41:19Speaker 2: and they got end organ damage or something worse, death.
- 41:23Speaker 2: And that's something that I think the regulatory side in
- 41:27Speaker 2: the U.S. is very good at, especially in phase two
- 41:30Speaker 2: and phase three, is patient safety. That is their mantra.
- 41:33Speaker 2: Your efficacy is your nickel, but FDA comes into the
- 41:36Speaker 2: discussion around patient safety. And I think the areas where
- 41:41Speaker 2: we can learn, especially if we look at what, you know,
- 41:44Speaker 2: Canada also has a fairly slow clinical development trajectory from
- 41:48Speaker 2: a regulatory perspective. But if you look at other Western nations,
- 41:51Speaker 2: Australia is amazing from a phase one perspective, just because
- 41:56Speaker 2: the filing package that you have to file in order
- 41:59Speaker 2: to go into phase one is so much less complex
- 42:03Speaker 2: than the IND that you have to submit to the FDA.
- 42:06Speaker 2: You don't have to have an IND to go into Australia.
- 42:08Speaker 2: You don't have to have the final reports. You do
- 42:11Speaker 2: have to have your GLP talk stated, and it is
- 42:13Speaker 2: reviewed by a committee. But oftentimes, getting those final reports,
- 42:15Speaker 2: getting everything certified, going through the INB process, that adds
- 42:19Speaker 2: six months of time. And so you can get into
- 42:22Speaker 2: Australia in phase one trials very quickly. I think kind
- 42:28Speaker 2: of the China-Australia question on how do we accelerate development, Initially,
- 42:34Speaker 2: I remember when people were first talking about Australian drug development,
- 42:38Speaker 2: people were talking about the tax credit and tax benefits. Now,
- 42:41Speaker 2: I think people have realized, it's okay, it's nice, I'll
- 42:45Speaker 2: take it on some of my programs potentially. But the
- 42:48Speaker 2: real savings is the fact that I can go into
- 42:51Speaker 2: my phase one, I can address some early pharmacology questions,
- 42:56Speaker 2: maybe some pivotal questions around target engagement, even healthy volunteers.
- 43:01Speaker 2: And I can do that three to six months faster
- 43:03Speaker 2: than I can in the US. And that's a big deal,
- 43:06Speaker 2: especially if you're a small biotech where your burn rate
- 43:08Speaker 2: is very sensitive. You think about six months is the
- 43:12Speaker 2: difference between failure and the company thriving, right? That's huge.
- 43:16Speaker 2: And I think we can learn from that. So there
- 43:19Speaker 2: are definitely things that we can learn from the Chinese
- 43:22Speaker 2: approach going faster. We have to go faster in a
- 43:24Speaker 2: very careful way, making sure that we don't sacrifice patient safety.
- 43:28Speaker 2: But We can look at other approaches to see how
- 43:31Speaker 2: we can preserve safety and still go fastly into the clinic.
- 43:35Speaker 2: could be my full complicated answer.
- 43:38Speaker 3: It was a good one.
- 43:39Speaker 1: I'm going to throw a follow-up and then one more question,
- 43:41Speaker 1: then I promise we'll let you go. But this has
- 43:43Speaker 1: been such a terrific conversation. On the concept of patient safety,
- 43:48Speaker 1: I was struck by some data that came out from MassBio.
- 43:52Speaker 1: They surveyed, I don't know, a lot of biotech leaders.
- 43:56Speaker 1: And something that came up that I didn't hear often
- 43:59Speaker 1: before is that our threshold for adverse reactions is in
- 44:03Speaker 1: the U.S. might be a little too high or low,
- 44:07Speaker 1: or depending on how you're looking at it, that that
- 44:11Speaker 1: threshold is maybe being triggered too early and that there
- 44:14Speaker 1: probably needs to be a little more tolerance for adverse
- 44:18Speaker 1: reactions or really how we're reporting adverse reactions. I don't
- 44:23Speaker 1: know if you've seen that data set, but it just
- 44:27Speaker 1: reminded me of it because you were talking about patient
- 44:30Speaker 1: safety as such a north star. Is that a trade-off
- 44:33Speaker 1: we need to consider or can we be competitive and
- 44:37Speaker 1: still keep that extraordinarily high bar?
- 44:40Speaker 2: It really depends on the indication. If we're talking about
- 44:46Speaker 2: transient renal impairment in the context of a third-line AML
- 44:52Speaker 2: drug where it's curative, I think we can be very
- 44:55Speaker 2: comfortable about that because often AML patients tend to be younger.
- 44:59Speaker 2: You're going to die, usually, if you can't treat the cancer.
- 45:05Speaker 2: And that transient renal impairment, if you go off the
- 45:07Speaker 2: drug after you've gone into remission or cure and your
- 45:11Speaker 2: kidneys bounce back, it's probably okay. Now, that being said,
- 45:15Speaker 2: a transient renal impairment in Parkinson's disease, I'm less inclined
- 45:21Speaker 2: to tolerate because it's an older population already. You tend
- 45:24Speaker 2: to have some kind of renal impediment just because of
- 45:27Speaker 2: the age. So I think it's really case by case
- 45:30Speaker 2: in terms of indication, patient population. And I think people
- 45:34Speaker 2: are getting smarter at that. Regulators definitely are starting to think, okay,
- 45:38Speaker 2: these blanket statements that we make for all patients, all conditions,
- 45:41Speaker 2: we need to start updating our guidance and be really
- 45:44Speaker 2: thoughtful on what we're demanding from a safety perspective. That
- 45:49Speaker 2: I think is happening out there. So that's really what
- 45:53Speaker 2: I would say is it really depends on your indication,
- 45:56Speaker 2: the kind of therapy that you're offering, and the background
- 46:00Speaker 2: patient population in terms of what constitutes truly a red
- 46:03Speaker 2: flag or maybe a proceed with caution.
- 46:06Speaker 1: I love that point that we probably need to get
- 46:09Speaker 1: away from blanket statements. The science and the precision has
- 46:13Speaker 1: gotten us to a place where some things make sense
- 46:15Speaker 1: over here, may not make sense over here.
- 46:17Speaker 3: Last question, you have been an advocate.
- 46:20Speaker 1: I've gotten to see you come up to DC to
- 46:22Speaker 1: meet with policymakers. And one of the ones you've talked
- 46:26Speaker 1: about is the continued small molecule penalty, this pill penalty
- 46:30Speaker 1: that is a part of the IRA. This is nine
- 46:35Speaker 1: years versus 13, pick whatever you want to call it.
- 46:38Speaker 1: Still an issue, still something you see out there, still
- 46:41Speaker 1: a problem. And does Congress need to get the EPIC
- 46:44Speaker 1: Act done?
- 46:45Speaker 2: Yeah, absolutely. You know, we at ALS, we in Epson
- 46:51Speaker 2: are working on ALS. You've got a couple of things
- 46:54Speaker 2: that present some headwinds occasionally that you're working in something
- 46:58Speaker 2: like amyotrophic lateral sclerosis. It's a hard disease, scares a
- 47:01Speaker 2: lot of people. And then there's the concern that payers
- 47:05Speaker 2: are going to depress your return at the end of
- 47:09Speaker 2: nine years because you're a small molecule. And so I
- 47:13Speaker 2: think EPIC Act needs to get done. There's still a
- 47:16Speaker 2: lot of excitement around it. The last time I was
- 47:19Speaker 2: up on the hill was in May and people were
- 47:21Speaker 2: talking about how we need to move this forward. We
- 47:24Speaker 2: need to remove the the pill penalty. Uh, and I
- 47:27Speaker 2: think it's time that we, we get that sealed and, and, and, and,
- 47:31Speaker 2: In the rearview mirror, because there are other more pressing
- 47:32Speaker 2: things that we need to talk about.
- 47:35Speaker 1: I think you're right. We covered a lot of them here.
- 47:37Speaker 1: This is going to be one of our standout episodes.
- 47:40Speaker 1: I mean, talk about a masterclass on AI in particular.
- 47:43Speaker 1: Congratulations to Avicenna. Congratulations on adding an investor hat. We'll
- 47:50Speaker 1: have to have you back on soon. Tom, thank you
