Transcript
- 0:06So welcome back to another episode of the Bio Hub and
- 0:09Avetics podcast. Today's guest is Handel Kim, Co
- 0:13founder and CEO of Variational AI.
- 0:16Variational AI is a Vancouver based company using generative
- 0:19AI to help biotech and pharma companies discover and optimize
- 0:23novel small molecule drugs. Since founding the company in
- 0:262019, Handel and the team have built a platform focused on
- 0:30exploring chemical space and accelerating early stage drug
- 0:34discovery. Pleasure to have you Handel.
- 0:36How are you I'm. Doing fine.
- 0:38Thank you very much. Pleasure to be here, Max.
- 0:41Now really good to have you. I think we we'll just start off
- 0:44with variational for, for those who don't know you guys, just
- 0:49tell us a little bit about you and the company.
- 0:51Yeah, absolutely. So we're based in Vancouver,
- 0:54Canada. We are 19 FTE, we've been around
- 0:59for oh almost seven years. So we, we were founded in
- 1:03September of 2019 and we focus exclusively on small molecules
- 1:10and now expanding into sort of these adjacent areas such as
- 1:14proximity based therapeutics like glues and protax, but also
- 1:19novel payloads for ADCS. And what we've done is we have
- 1:22developed our own foundation model for a small molecule
- 1:27generation. We it's called Enki and it forms
- 1:31the basis of our platform that we use to help biotech companies
- 1:36from small emerging biotech companies that are looking to
- 1:39hit some kind of inflection point in value all the way up to
- 1:44big pharma. And we're pleased to announce a
- 1:48collab with Merck MSD in September of last year 2 program
- 1:53deal $349,000,000. And so that's great validation.
- 1:57And we heavily leverage AI, we're AI 1st and myself and the
- 2:03Co founders, we come from a company called D Wave Quantum,
- 2:06which is now publicly listed and is a quantum computing company.
- 2:10But we were working on probabilistic and generative
- 2:13machine learning. And so that's that's where the
- 2:16team came from. And we have purpose built our
- 2:18own foundation model for this purpose.
- 2:21It is not an LLM and it is not software.
- 2:25Basically what happens is a partner will define their target
- 2:30product profile, a preclinical target product profile and, and
- 2:33he will generate these novel structures extremely
- 2:36efficiently. And we have a very high success
- 2:39rate in terms of being able to generate leads like right out of
- 2:43the model. So you can skip hit ID, you
- 2:45don't need to do a screen. And then we go in and do lead
- 2:50optimization as well. And then we, we get out.
- 2:53We don't have our own pipeline, we don't have our own assets,
- 2:55but we're really there to, to, to help the biotech companies.
- 2:59The team is composed mainly of machine learning and chemists.
- 3:03We have computational chemists and medicinal chemists in order
- 3:06to be the ones that look at the output of the molecules made by
- 3:10our machine learning scientists and curate and collate and
- 3:16provide those to chemistry teams.
- 3:18So we are AI 1st and we love working in the domain of small
- 3:23molecules because it's very different than than biologics,
- 3:26where I think the adoption of generative AI has really taken
- 3:29off. Yeah, I think this, the small
- 3:31molecule pieces is interesting. What?
- 3:35What was it that originally convinced you that there was an
- 3:38opportunity for AI to make such a meaningful impact?
- 3:41Well, you know, we, we published some results and delivered a
- 3:47paper at Nurips back in 2019 where we showed state-of-the-art
- 3:51results in molecular property prediction optimization, where
- 3:55we outperformed labs from, you know, from MIT and Stanford and,
- 3:58and various other places. And we thought, hey, you know,
- 4:02let's go do drug discovery, not really knowing anything about
- 4:05drug discovery or biotech, just as naive sort of machine
- 4:09learning people and, and software people.
- 4:12And that's why it's taken us almost seven years to get to a
- 4:16stage where we are, it's, it's very difficult.
- 4:19So we went into small molecules because that was what we
- 4:23developed the, the algorithm and the model for.
- 4:26There's, you know, training data and you know, we, we actually
- 4:31wanted to 1st apply the approach to other types of molecules, you
- 4:35know, polymers or, you know, OLED materials, you know, metal
- 4:42organic frameworks, various other sort of smaller molecules.
- 4:45Because we knew that we didn't really know anything about,
- 4:48about biopharma, but then we realized that, hey, there's no
- 4:55data. And the only place where there
- 4:58is enough data to train on was in, in, in biopharma.
- 5:03And as a result, we said, OK, well, we're machine learning,
- 5:06we're not magic. So we need data on which to
- 5:09train. So we decided to go into, into
- 5:11drug discovery. And so that was really sort of
- 5:14the impetus you go where the data is.
- 5:16And, and at that time, the, there were no large language
- 5:19models that were really as performing and nearly as
- 5:23performing as there, there are today.
- 5:26And so you didn't see the sort of the take off of the adoption
- 5:30of sort of protein language models.
- 5:32And there was no alpha fold at that time.
- 5:34But also our approach was specific to small molecules and
- 5:39applying AI to biologics is a completely different
- 5:41proposition. And there's some great companies
- 5:43doing some incredible things in that that domain.
- 5:46But it's really a sort of a tale of two modalities, if you will.
- 5:50So I think that and now we see sort of crossover and we see
- 5:53some some really, really interesting, you know, players
- 5:57and models, you know, Co folding, etcetera, etcetera,
- 6:01which is really, really, you know, exciting and it's a great
- 6:05time to be there. But when it comes to hardcore
- 6:07generation of ligands that are predicted to and then actually
- 6:11in experimental validation, actually, you know, bind and
- 6:15have potency and, and, and selectivity and, you know, have
- 6:20the right PK and, you know, have a good talks profile, that still
- 6:25remains a fairly rarefied territory.
- 6:29I think a lot of people when they see AI for drug discovery,
- 6:32they just kind of clump everything in together.
- 6:34And if you kind of look at what what companies are doing, not a
- 6:37lot of companies are doing what we do.
- 6:39I mean, they're, you know, a small number of companies that I
- 6:42think are credible in doing what, what, what we do, which is
- 6:45the, you know, the generation of novel molecules.
- 6:48And then it's also compounded by, you know, all do these open
- 6:51source models, which are which are wonderful.
- 6:54But then you know, really limited by sort of the, the
- 6:57scientific, the machine learning science depth of your team,
- 7:02which is still relatively shallow in biopharma.
- 7:07Would you say that's been the main challenge in your growth
- 7:09and sort of where you're going as a as a company?
- 7:12Well, I mean, not for less for us than than I think, you know,
- 7:18pharma or biotech and, and largely it's because, you know,
- 7:23AI is still a bit of a, a black box, but it's changing.
- 7:26We're starting to see a greater sophistication and nuanced
- 7:31understanding of what, what machine learning is and, and
- 7:34where it works and where it doesn't.
- 7:36But by and large, you know, when we entered the scene, there were
- 7:39a lot of companies doing AI for drug discovery.
- 7:42But when you scratch the surface and look at their, their, their
- 7:45AI people, they were largely computational chemists or, you
- 7:49know, statistical, you know, bioinformations or bio, you
- 7:54know, so and which is great. And, and these are people that
- 7:57are expert in their domain and they apply AI as a technique
- 8:02which can yield some really good results.
- 8:05But at the end of the day, if you want true innovation in AI,
- 8:07specifically for the domain, you're going to only get it from
- 8:11the science part of AI. And I think that was something
- 8:15that a lot of people didn't quite understand that that
- 8:18machine learning itself is a science.
- 8:19It's an information science, just like chemistry and biology
- 8:23are sciences, no experimental sciences.
- 8:27And you know, the, the, I always say, like, if you have a really,
- 8:31you know, thorny chemistry problem, you're not going to go
- 8:33up to a, you're not going to ask a pharm pharmacologist or, or a
- 8:36biologist, you know, you'll ask a chemist.
- 8:40And so if the challenge is really making AI work for you,
- 8:44then why wouldn't you go to an AI scientist, right, instead of
- 8:48going to a chemist or, or, or, or a biomedical engineer or to a
- 8:53biologist? And, and I think that's sort of
- 8:56been the challenge because for the domain of biopharma to
- 8:58access that level of scientific ability has been challenging
- 9:03because as well as, you know, as, as, as the industry pays it,
- 9:08it, it pales in comparison to what the machine learning
- 9:11industry pays. But more than that, it's about,
- 9:15you know, the use of machine learning.
- 9:17And, and if, if you could take your pick of going to work for,
- 9:22you know, anthropic or, or, you know, meta or go work for, you
- 9:27know, a pharma where you're going to be stuck in an, in a
- 9:29corner of the, of the company and just running models and not
- 9:34really being able to implement them, then it's a pretty easy
- 9:37decision in in addition to the fact that you're getting paid
- 9:39like two or three times more, you know, working at a, at a big
- 9:44AI company. So I think there are a lot of
- 9:46sort of systemic issues with breaking in cutting edge AI
- 9:50research. And I think also that the a
- 9:53pharma is not necessarily optimized structurally or
- 9:58organizationally to do innovation in AII mean
- 10:02certainly, you know, you're, you're in licensing as a pharma
- 10:06many assets from biology, from biotechs.
- 10:09So you're already very, very adept and well practiced in, in,
- 10:15in outsourcing innovation and then acquiring it, right in
- 10:18order to do the commercialization, which is, you
- 10:20know, the where, where, where pharma shines.
- 10:22Obviously they still do core R&D and they have to, but at the
- 10:25same time, I think you know, at least half of all programs, you
- 10:30know, and or commercial programs in pharma are basically in
- 10:34license from biotech. So why on earth when they do the
- 10:36same for AI because AI is even is even second or third order
- 10:40from biology and chemistry. So if you're already doing it
- 10:43for biology and chemistry, which is core, it stands to reason
- 10:46that that you wouldn't do it for AI.
- 10:49And So what we found is that most pharma are doing AI largely
- 10:55to understand how to evaluate other partners, right?
- 11:00Because if you don't have internal capabilities or
- 11:03understanding, then then how do you evaluate A partnership?
- 11:07So, and I think in, in the first generation, you know, back in,
- 11:11excuse me, like 20/17/2018, you know, before COVID, I think
- 11:16there were a lot of deals were, that were done because no one
- 11:20really knew anything. And so, hey, it's the the new
- 11:22shiny thing. And I think, you know, in the
- 11:24intervening number of years, I think AI has made a tremendous
- 11:27impact. There are a lot of companies out
- 11:28there that are delivering, you know, tremendous value and
- 11:31innovation for, you know, pharma partners and for biotechs in
- 11:34general. And I think we're starting to
- 11:36see a subtle, but not so subtle change in understanding where AI
- 11:41works well and where it can, where it doesn't.
- 11:44And so we're seeing the, the adoption and sophistication of
- 11:48partners grow rapidly and and that's welcoming to us because
- 11:54we don't have our own internal pipeline.
- 11:55We, we partner with everyone. So we're we're picks and shovels
- 11:58for a is for drug discovery. And you raised some interesting
- 12:02points there as well. You know, a is you guys got in
- 12:05pretty early in terms of how the AI market shifts, but but now
- 12:10it's becoming increasingly crowded, right.
- 12:13Well, what do you think makes you guys different to to some of
- 12:18the other companies out there? Well, you know, there's, there's
- 12:22the actual science and you know, the power of the model and which
- 12:26is, you know, completely dependent on the expertise of
- 12:29the team. So, you know, we've got a a
- 12:31world class team, but then everyone says they do right.
- 12:33So that that's that's tough to differentiate.
- 12:37But you know, it is actually a lot easier to determine whether
- 12:40or not a machine learning team has the chops and the true sort
- 12:45of scientific skill, which is have they published a conference
- 12:49paper at a major, you know, machine learning conference like
- 12:53eye clear or nerves or CML, right?
- 12:57Did they come out of a reputable lab?
- 12:59Like is there, is there, is there grad work in machine
- 13:04learning or is it in a different area?
- 13:06Right? Because if it's not in computer
- 13:09science or, you know, applied bath or stats or, or
- 13:13computational neural systems or, or these programs where you're
- 13:17doing machine learning science, then you're not really a machine
- 13:21learning scientist, right? And so it's, and then you know
- 13:25what? Whose lab did you come out of,
- 13:26right? You know, did you come out of,
- 13:29you know, you come out of like, you know, the rich Sutton lab
- 13:34and University of Alberta, your reinforcement learning person,
- 13:36you come out of the banjo labs, you come out of the lacun like
- 13:39Quran, etcetera, etcetera. It's, it's very easy to tell if
- 13:43you actually all you need to do is is spend, you know, a few
- 13:46minutes to understand where people come from.
- 13:48Is it reputable lab? But then it, it's, it's, I don't
- 13:53necessarily see the, the, I think that's changing.
- 13:56But when people sort of otherwise, you know, we see a
- 13:58lot of people in biopharma, they go, Oh yeah, we've got a this,
- 14:02this AI expert. And usually that person will be
- 14:05quite cheap. They should go like, well, I'm
- 14:07not, I'm actually a computational chemist and I, I
- 14:11really enjoyed this AI. But it's, it's just kind of
- 14:13like, it reminds me of the Internet, you know, back in the
- 14:16late 90s where, you know, you have all these people who don't
- 14:19really understand technology and they go like, oh, hey, you young
- 14:24person, right, You're on this Internet thing all the time.
- 14:27So can you write me your Internet strategy?
- 14:30And, and this person's like, oh, OK, like I just, I just started
- 14:34playing with Mozilla. I just started doing this.
- 14:36I, I can do some Java, but you're our AI guru now.
- 14:39And then they go like here, you know, step forth our champion.
- 14:44And so we see, you know, some shades of that in, in AI and,
- 14:48and I'm sympathetic because if you're an experimental scientist
- 14:52and you're in drug discovery and you see all of this hype and
- 14:55your, your investors and your board are saying, what's your AI
- 14:58story with? And you're like, I'm, I'm trying
- 15:00to, trying to make a, I'm trying to hit rheumatoid arthritis with
- 15:03a small Mulligan. So it's a, it's a, it's a hugely
- 15:07difficult biology and chemistry problem.
- 15:09What do I need AI for it? It's like, OK, let me, let me
- 15:11get them off my back. And so a lot of sort of this AI
- 15:15stuff is performative, right? But I think we're moving from
- 15:19performative to, and we're also seeing when we interact with,
- 15:23with potential partners, it's less about like, why AI to like,
- 15:26how, like, how would we use this?
- 15:29How would we work with you or someone else?
- 15:32And so that, that is, you know, a pretty significant shift, but
- 15:36you know, it's, it's a, it's a really interesting time.
- 15:39I think we're starting to see a bit of an inflection point in
- 15:42terms of the adoption. So I guess getting back to your
- 15:44question though, what's, what's our differentiation?
- 15:47I mean, there's the science part and that's, that's pretty,
- 15:51that's pretty, you know, easy to understand.
- 15:55But honestly, it's, it's our business model, right?
- 15:58Had we gone in. So we, we, we were thinking
- 16:02about, you know, applying our model and key to develop our own
- 16:05assets and our own pipeline. We actually went far down this
- 16:08path, you know, a number of years ago.
- 16:11But I'm pretty convinced that had we actually, you know, gone
- 16:13through and raised the money and deployed the capital, that we'd
- 16:16be dead right now. Because, you know, AI and
- 16:21specifically generative AI in, in small molecule, you know,
- 16:25discovery and development. The discovery has been pretty
- 16:28well validated. I mean, there are many companies
- 16:30that are showing, you know, tremendous efficiencies and
- 16:34success in the early stage. And I think even, you know,
- 16:37people who would would actually be, you know, rightfully cynical
- 16:41about some of this, like, you know, your Pat Walters or or,
- 16:44you know, your Derrick Lowe's or whatnot.
- 16:45They all concede like, yeah, yeah, OK, yeah, they can
- 16:47generate all these molecules, but that's not the main thing,
- 16:50right? And that's just a small part of
- 16:53the difficulty and the risk in doing drug discovery and
- 16:56development. And I completely agree.
- 16:58And further, you know, what is the probability of success of an
- 17:03AI discovered molecule in clinical development?
- 17:06And I think, you know, there's some data that says, you know,
- 17:09oh, Phase 1, you know, you have a higher rate.
- 17:11Well, OK, that, that's pretty, that's pretty easy.
- 17:14Just, you know, just file your Ind and, and hopefully you're,
- 17:16you're in the clinic. But then the the phase two sort
- 17:20of Cliff like it's, there's no increased probability of success
- 17:24in Phase 2. And that's largely because you
- 17:27know, it's not a problem that AI necessarily solves.
- 17:30When you have an AI developed molecule, you know, it fits to
- 17:33the properties that you define. And if the properties are wrong
- 17:36or the target is wrong, then you don't have a drug.
- 17:39And so we still the jury is still out in terms of what the
- 17:43probability of success in phase two and late stage clinical
- 17:46trials are. And until that moves
- 17:48appreciably, I think you're still taking a lot of risk as an
- 17:52AI for drug discovery company if you have your own assets, right.
- 17:56And we've seen this with several companies, you know, quite a few
- 18:00companies that are quietly or not so quietly, basically, you
- 18:03know, pivoted tremendously away from that companies such as, you
- 18:07know, your benevolence or your verges or whatnot, you know, ex
- 18:11ancias, etcetera, etcetera. I mean, AI, but as, as Alex
- 18:14Jaber Ankov in silico says, is like, yeah, you can, you can do
- 18:17all this stuff, but once you're in the clinic, you're moving at
- 18:19the speed of traffic. Completely agree.
- 18:22And So what you're doing is you have more shots on goal and you
- 18:24got like, you know, hey, maybe you got 20 programs that you're
- 18:27that you want to put into the clinic, but how the hell are you
- 18:29going to fund them, right? And So what you're what you're
- 18:32going to see is and what you are seeing is a lot, a lot more
- 18:35assets available for licensing and partnering from AI based
- 18:39companies. Because you know, at the end of
- 18:41the day, you're still, even if you raise hundreds of millions
- 18:43of dollars, you can only take one or two of these programs
- 18:45into, you know, into, into clinical development and then
- 18:48beyond. And I think really what you're
- 18:50starting to see is maybe a surplus of assets of quality,
- 18:54you know, in addition to what you can go to China and get
- 18:56right. But I think that's really the
- 18:59impact is it should be a, a buyer's market of assets for
- 19:04biopharmers. And I think that that part of
- 19:08the development becomes almost commoditized or becomes a lot
- 19:11more efficient than it's been in the past.
- 19:14And then so really it's, it's a, our, our primary thesis is that,
- 19:18yes, we have, you know, in my opinion, the best, you know,
- 19:21generative model for small molecule, you know, drug
- 19:25discovery. But at the end of the day, it's,
- 19:27it's our model that differentiates us.
- 19:29Because if you're a biopharma, where are you going to get AI?
- 19:32You, you, it's, it's very hard to hire people of sufficient
- 19:36scientific, you know, experience and knowledge to do that.
- 19:40And also they're going to be sitting alone and then, you
- 19:43know, forget about your AWS costs and this and that.
- 19:47We're just, we're just there to provide that, you know, in
- 19:50partnership, you know, with, with biopharmas.
- 19:53So I think that that is a right market for us.
- 19:56And I think that is our primary differentiation is that we've
- 20:00already done it and we're we're happy to to share that with with
- 20:03with. You know, with our ecosystem.
- 20:06Yeah, I love that. I love that.
- 20:08And if if you're a biotech who's currently brilliant discovery
- 20:12program, where does AI then have the greatest impact on them?
- 20:17You know, on timelines, costs, probability of success?
- 20:21Yeah. So I mean, you know we have
- 20:23several offerings at different stages of growth, right, and
- 20:26stages of the of early stage discovery.
- 20:29So at the very beginning, you know, you you're looking at a
- 20:32program, you want to do some early discovery.
- 20:35You know, the biologists have spent a lot of time, you know,
- 20:37teasing out an MOA in a, in a, you know, an indication and
- 20:41you've got some insight, right? And now you need to get some
- 20:44chemical matter. So you go to acro, you do a
- 20:46screen, you do virtual screening, you do all this or
- 20:48that. And you're, you know, you're
- 20:50trying to find something that gives you signal that yeah, I
- 20:54can, I can, I can find a molecule and then you Med chem
- 20:56your way to that. And so at that stage, that's
- 20:59that's where we come in. So instead of using the same
- 21:01starting points that everyone does who's going after the same
- 21:04target and the same indication, there's always multiple parties
- 21:07going after the same, you know, targets at the same time, but
- 21:12everyone starts from the same sort of starting points.
- 21:15Well, why don't you start with novel starting points and gets
- 21:17you into FTO, but also gives you differentiated molecules in
- 21:22different areas of chemical space.
- 21:25When we, when we look at drug discovery, there's the, the
- 21:27exploration phase and then the exploitation phase.
- 21:31And so exploration is really about like trying to find, you
- 21:35know, really, really different and novel and differentiated,
- 21:39you know, hits and starting points.
- 21:41And it's really hard to do that. You can't just randomly sample
- 21:45chemical space. It's just too massive.
- 21:47You won't find anything. And if you start so therefore
- 21:51you start from known compounds, tool compounds or things that
- 21:54are out there and then you go, OK, let's start here and then
- 21:57let's try and you know, you know, Med chem our way into
- 21:59novelty and let's, you know, scaffold top or let's, you know,
- 22:03do just, you know, walk the nitrogen around, change this,
- 22:06you know, our group or whatever, whatever.
- 22:08But as, as everyone knows that it's, it's a painstaking and
- 22:11long process and it's expensive. That's your exploitation.
- 22:15But people shortchange the exploration phase because where
- 22:18do you get novelty, right. So I'll just start here and then
- 22:21I move right into exploitation. That's why that exploitation
- 22:25phase. And, you know, hit the lead and
- 22:26lead optimization takes so long and has, you know, not a great
- 22:30rate of success. And basically programs die when
- 22:33you run out of budget and you run out of time.
- 22:37And, you know, assuming infinite time and infinite money, yeah,
- 22:39you know, the, the, the success rates would, would be very high,
- 22:43but they're not. I mean, you're in a competitive
- 22:45situation. So really what we're saying is
- 22:47that the exploration of chemical space, finding different areas
- 22:53to start, that is the really the key.
- 22:56Because when you find these different areas and different
- 22:59sort of, you know, chemical, you know, structures that other
- 23:02people are not starting from, the exploitation phase is
- 23:07reduced. And if you look at costs and
- 23:09timelines of discovery, lead optimization is obviously the
- 23:13longest and the riskiest part of drug discovery in pre in the
- 23:17clinical side. But if we could reduce that risk
- 23:20and reduce the time and the cost, right, then we think we
- 23:23have a very transformative, you know, value proposition.
- 23:26That's that's what that's what we're about.
- 23:27I mean, our our sort of explicit tagline is to redefine the unit
- 23:31economics of drug discovery. And so that that's really what
- 23:33we're focused on. So that I would say that that is
- 23:35our primary differentiation. We're not trying to make drugs.
- 23:38We're trying to make molecules that can become drugs for our
- 23:41customers, and we can do it about 100 times more efficiently
- 23:45than status quo methods. Oh, it's so true.
- 23:47That so, so true. You know, like there's a bunch
- 23:51of companies that are trying to recreate what you have in house
- 23:53as well, right? Like it's, it's interesting for
- 23:56sure. Yeah, yeah.
- 23:58Why, why? Why do that?
- 23:59We can do that for you and then you can focus on the hard stuff,
- 24:02you know? Exactly.
- 24:04So, so true. I mean, you, you think about
- 24:07variational as a company, it's taken 7 years per FET.
- 24:09What you guys have like it's, it's the right way to go, right.
- 24:15But yeah, look, it's been awesome having you on.
- 24:17Ando. It brings us to a final
- 24:19question, which is a bit of a change of topic, but it's a
- 24:22question we ask every guest. Umm, if you could have dinner
- 24:26with any scientist or innovator, past or present, who, who would
- 24:30it be and why? I'd be Nikola Tesla for sure.
- 24:35Love that answer. Yeah, yeah, I mean, it would
- 24:37just like what? What awesome, amazing weirdness.
- 24:42Umm, would, you know, sitting down with him and Mark Plain,
- 24:45you know, like in in New York at the time and maybe JP Morgan.
- 24:49But yeah, Tesla would be would be fantastic.
- 24:53And then I'd also be able to see if he was actually an alien or
- 24:55not. But yeah, Tesla for sure.
- 24:59Love that answer. Look, it's been a pleasure
- 25:01having you on handle. Please everyone like and
- 25:04subscribe to the bio hub and and thank you so much.
- 25:07Thank you, Max.
