Transcript
- 0:05Welcome back to another episode of the Biohub podcast.
- 0:07Today, we're joined by Cameron Turtle of Spio Therapeutics, and
- 0:11we're live in London from Jeffries.
- 0:14Welcome to London. Yeah, Thanks for having me.
- 0:16Yeah, awesome. How have you found things so
- 0:17far? It's great.
- 0:19I I normally live in Seattle and so the weather in London is not
- 0:21all that different, so it's good to be here.
- 0:23Yeah, perfect much. It's getting a little bit
- 0:25colder. It is.
- 0:26Yeah, it is. Yeah.
- 0:28Nice. No rain yet.
- 0:29Yeah. And you've been here since the
- 0:31weekend and. Yeah, the weekend we were here
- 0:33for an investigator meeting recently with some of our
- 0:35European investigators. So it's the first time I've done
- 0:38this conference not overly jet lagged, which is great.
- 0:41Always bonus. Yes, yeah, exactly.
- 0:43Nice. Awesome.
- 0:44Well, let's get into it I guess. Yeah, we always sort of start
- 0:48off with a little bit of background on on yourself rather
- 0:50than just just fire, evidently. So, yeah.
- 0:53Can you walk us through your sort of journey in biotech?
- 0:56Yeah, sure. So training originally as a
- 0:58scientist actually did my my PhD over here in Oxford of
- 1:03cardiovascular medicine genetics and the inherited
- 1:06cardiomyopathies as as my PhD. And then I've been in the US
- 1:09doing US biotech ever since. So it's been a little over a
- 1:12decade now initially consulting, then I spent five years at a, at
- 1:16a company that was very small when I joined and not so small
- 1:19anymore called Bridge Biopharma. And then, you know, right about
- 1:243 years ago, I had the opportunity, I kind of got a
- 1:25call to, to look at this company Spire to potentially come be the
- 1:29first employee and, and CEO here and thought it was a great idea
- 1:33when it was pitched to me. And so I came over and doing
- 1:35that for the last three years or so.
- 1:36Yeah, nice. And walk us through a little bit
- 1:39about the origins of Spire, because it's a pretty, yeah,
- 1:42interesting story. Yeah, yeah.
- 1:45I mean, though I was the first employee, I don't really take
- 1:47credit as a founder here. A lot of the initial ideas are
- 1:50not not exactly mine. I think it's actually pretty a
- 1:53clever approach that this investor group called called
- 1:55Fairmount had, which is kind of looking at the the broad
- 1:58therapeutic landscape and seeing quite a few biologic therapies,
- 2:02notably antibodies that kind of they've proven that they work on
- 2:06a particular target in terms of great safety and efficacy, but
- 2:09oftentimes left quite a bit to be desired in terms of the
- 2:12product profile. And this was in a range of
- 2:14different therapeutic areas. And, and I think using what we
- 2:18know about antibody engineering today, there's a lot of ways to
- 2:21improve the properties of the antibody, notably mechanisms
- 2:24that are pretty well proven to meaningfully extend the half
- 2:27life of an antibody without affecting its immunogenicity,
- 2:30its potency, its selectivity. So just really a better antibody
- 2:33frankly. And then simultaneously can also
- 2:36improve formulations and other things along the way.
- 2:38So it gives an opportunity to make, I think, at a relatively
- 2:42low biologic risk, a meaningfully better product
- 2:45against a proven target. So they've been doing this for a
- 2:48few years and they saw this opportunity in inflammatory
- 2:51bowel disease where exactly what I just described was the case.
- 2:55There was a bunch of these biologics that had been
- 2:56developed, leading products in the space, kind of mega
- 3:00blockbuster products in terms of sales.
- 3:03And they're being delivered, you know, every two weeks
- 3:05subcutaneously, which we know we can do a lot better than that.
- 3:09And it's also the case that sometimes with these extensions
- 3:12of half life, you can also improve more than just the
- 3:15convenience of these antibodies and how they're dosed.
- 3:17You can also, you know, you can get more drug on board at
- 3:20through levels without having to give as much at the Max levels
- 3:24of the drugs. You can sometimes get kind of an
- 3:26improvement in safety or efficacy as well with this
- 3:29approach. So they've been doing this in a
- 3:31bunch of areas. They thought IBD was was ripe
- 3:34for this opportunity and spent a couple years making new
- 3:38antibodies against what I, I still think actually are the
- 3:40best targets in the space. So it's A4 beta 7, which is the
- 3:43same target as a drug from Takeda called Entyvio.
- 3:47The second one is a against a target called TL1A.
- 3:49There's no commercial products there yet, but I think it's one
- 3:52of the most exciting targets in in, in I and I actually more
- 3:56broadly. And then lastly, a target called
- 3:58Illinois 23, same target as Skyrizi and Tremfya.
- 4:02And so we made what I think are better versions of each of these
- 4:05and we'll get into a bit more detail.
- 4:06But they pitched me on that and I said, look, this is this is a
- 4:08high probability way of making a great product.
- 4:10And so joined you almost three years ago and built the company
- 4:14from there. So what when you got the call
- 4:17like, how did they pitch it to you?
- 4:18Was it about the modifications and?
- 4:21Yeah, that was that was really the start, which was kind of
- 4:23kind of largely what I mentioned there, which is let's take what
- 4:26are currently the best biologics in the space, make them
- 4:29meaningfully more convenient, right.
- 4:31So we can take things that are now we've we've shown phase one
- 4:33data for each of our antibodies now.
- 4:35So in humans, we've shown that for each of these antibodies,
- 4:38they have more than three times the half life of the first
- 4:40generation molecules. And we have higher concentration
- 4:43formulations and kind of show that we can you know, hit these
- 4:46targets as well or better than the first generation ones with
- 4:49much longer dosing. And so we think we're we're
- 4:52going to be dosing in our face while we are dosing in our phase
- 4:55two trial that have started either twice a year or four
- 4:58times a year in the maintenance setting.
- 4:59So just a dramatic improvement in convenience and not just
- 5:04convenience almost certainly improves adherence as well.
- 5:06As in if you miss by a week or two when you're taking something
- 5:09quarterly doesn't make a huge difference.
- 5:13And, and even more so when you're dosing twice a year.
- 5:15Whereas you know, when you're, when you're thinking about your
- 5:17disease, you have to take something every week.
- 5:19You always have a shot in your fridge.
- 5:21You don't forget that you have the disease.
- 5:23You're thinking about it every day, especially in IBD, these
- 5:26patients are diagnosed median age is in college age years.
- 5:29So you're talking about college age kids and median means half
- 5:33are younger, right? So you're talking about kids,
- 5:35college students who are having these biologics all the time in
- 5:39their fridge. They always have to be thinking
- 5:40about it when they're traveling. They always have to be worrying
- 5:43about it as well. I think this approach removes
- 5:46that. It means you can take it, you
- 5:47know, on the road, you can plan around it much more easily when
- 5:50you have this, this infrequent dose.
- 5:52So much more convenient for sure.
- 5:54Yeah, and the, and the other pitch was, hey, maybe it's not
- 5:57just more convenient too. You can sometimes learn from how
- 5:59these drugs were made and against each of the targets
- 6:02we're looking at what we see in kind of sometimes you don't see
- 6:05it until the late trials, the phase three or even in the real
- 6:08world that maybe the first generation product wasn't
- 6:11actually the right amount of drug that that they delivered.
- 6:13We're all making these decisions with incomplete information
- 6:16during the drug development process.
- 6:18And so it actually looks like we might be able to get better
- 6:20efficacy in some cases too by having more drug on board either
- 6:24in the induction phase or in the maintenance phase of treatment.
- 6:27And so we're aiming for each of these monotherapy products to
- 6:30be, you know, at least as good efficacy as what's on the market
- 6:33today and meaningfully more convenient.
- 6:35And I think that's that's a step forward that we see is kind of
- 6:38as as important to patients and physicians.
- 6:40And when we spoke beforehand like it's quite a simple
- 6:44modification really, right? Yeah.
- 6:46It's a 3 amino acid substitution.
- 6:48It's a relatively small change to the antibody that leads to
- 6:51this meaningful impact. And I think we and others have
- 6:54shown it doesn't typically impact the other aspects of the
- 6:57antibody either, the potency, the selectivity, which
- 6:59translates to the safety and efficacy of the antibody as
- 7:02well. So I think it's a relatively
- 7:04simple approach, relatively low biologic risk with a pretty high
- 7:08probability of delivering a superior product.
- 7:10Yeah, for sure. I mean, normally when you think
- 7:12of it, I mean simple terms, I'm not a scientist, but when you
- 7:15think of putting a higher dose in, you worry about right side
- 7:19effects, toxicity, whatever. Like, did the changes reduce
- 7:24that risk? Yeah.
- 7:25So, so two things that I think are important is that one, we
- 7:28can get better coverage of these targets without actually giving
- 7:32more drug. In many cases, we can deliver
- 7:34less drug and still get better coverage.
- 7:36And, and what you care about in many cases is what we call the
- 7:38peak to through ratio, meaning how much drugs you have to give
- 7:41at maximum concentrations to achieve your target level of
- 7:44coverage at through concentrations.
- 7:46And because we have these long acting antibodies, you can
- 7:49actually give quite a bit less at Max and have the half life
- 7:53kind of lead lead to higher through levels as well.
- 7:55So that's why I think the key advantage is you actually don't
- 7:58have to more antibody to get the same coverage level.
- 8:01And then importantly, we're picking targets in in IBD and
- 8:05elsewhere that really do not come with meaningful safety
- 8:08risks. So they're they're kind of are
- 8:10not kind of compared to other targets in inflammatory bowel
- 8:13disease. The ones we've picked are the
- 8:15ones that do not have black box warnings for serious infections,
- 8:18malignancies and other things. And that really would be a
- 8:21limitation. You may not want a long acting
- 8:23drug if you have serious safety concerns, but that's part of the
- 8:26reason why we picked those. It was that, you know, you can
- 8:29have long acting versions and not have much to worry about,
- 8:31yeah. And that through level is super
- 8:34important in a chronic condition.
- 8:36That's, so that's, I mean in again, we get to learn from what
- 8:39the first generation products did here.
- 8:41And for each of them they've shown especially the ones that
- 8:44have really large data sets like Entyvio, they see a pretty
- 8:48strong correlation between efficacy and the through levels
- 8:51of the drug. Meaning, you know, the more the
- 8:53higher your through levels are, the better the drug seems to
- 8:55work. And so that's a major advantage
- 8:57for a product like ours where we can get those through levels up
- 9:00without having to get a lot more drug.
- 9:02Yeah. Sure.
- 9:03And those switches, those modifications are one part of
- 9:07your approach. You also, you're running the
- 9:10monetary trials, right, But you're also looking at
- 9:12combinations as well, which in the face of it makes a lot of
- 9:15sense in. So inflammation is a pretty
- 9:18complex process with lots of different factors involved.
- 9:21You want to walk us through what you're doing with those trials
- 9:23as well? To be honest, that's what got me
- 9:25excited about this, this opportunity to lead the company
- 9:27here. Inflammatory bowel disease is a
- 9:30really challenging disease to manage.
- 9:32You know, we've been working on advanced therapies for IBD for
- 9:36three decades plus. There's now meaningful progress,
- 9:40a half dozen different approved classes.
- 9:42And yet the physicians still refer to what they call the
- 9:44therapeutic ceiling, which means that you kind of across all of
- 9:47these classes, you really cannot get above about a 25% clinical
- 9:51remission rate. So only one in four patients
- 9:53treated with all these different drugs gets into remission.
- 9:56And those patients, they lose it over time too.
- 9:59So you lose response, you lose remission.
- 10:01And So what patients and physicians do is they often
- 10:03cycle through many different drugs, rarely getting into
- 10:06complete remission. And then the consequences of
- 10:08these diseases, diseases are, are pretty drastic.
- 10:10You can have surgeries, hospitalizations, major quality
- 10:13of life impacts. And So what was done in the real
- 10:16world was that physicians kind of had the these patients that
- 10:19they really could not manage with any of the products that
- 10:21they had available, even if they started to have many.
- 10:24And so this what they started to do was testing multiple of them
- 10:27in the same time. And, and sometimes because these
- 10:29drugs can be expensive, as you know, kind of sometimes play
- 10:32games where they get one drug prescribed for their IVD and try
- 10:35and get another drug prescribed for psoriasis that they might
- 10:38have or something other condition to try and get
- 10:40multiple drugs on board. And, you know, dozens of
- 10:43publications now of physicians all over the world testing these
- 10:46combos and seeing that patients that are, you know, not
- 10:49responding to anything that are starting to respond when they
- 10:52can hit the disease with multiple pathways at the same
- 10:54time. And as you pointed out, it makes
- 10:57sense in a disease that's not driven by 1 pathway.
- 10:59There's multiple things driving this disease.
- 11:01The idea that blocking any one thing would be a silver bullet,
- 11:04it's probably a bit fanciful. So, so, so now and then, right
- 11:08as we were launching Spire, one of the first randomized trial
- 11:11came out in IBD. So J&J ran a trial, randomized
- 11:15combo trial where they tested their two drugs.
- 11:18They have an IL 23 inhibitor and a TNF inhibitor.
- 11:21They each got about a 25% remission rate like everything
- 11:23else does. And then they tried the
- 11:26combination, the 2 of them and they got a 47% clinical
- 11:28remission rate, almost 1 + 1 was two really kind of, I think gave
- 11:33this field this hope that it might be possible to get
- 11:36meaningfully better efficacy by blocking multiple pathways.
- 11:40And so when we saw that they said this is it, this, this is
- 11:43what we have to go after. Once you see that level of
- 11:45efficacy, there's there's no going back.
- 11:47It's almost double right? It's almost double.
- 11:50And again, this disease is incredibly challenging to
- 11:52manage. It's incredibly costly to
- 11:54manage. The consequences of the disease
- 11:56are incredibly both damaging to the patients and, and their
- 11:59lives and their caregivers and really expensive from a, from a
- 12:02health system perspective to hospitalizations and surgeries
- 12:05are really costly. So, so this is kind of an
- 12:08opportunity to, you know, meaningfully, you know, get
- 12:11patients into remission faster to keep them in remission
- 12:14hopefully longer and then avoid those consequences that
- 12:17meaningfully impact their life and cost them in the system a
- 12:20huge amount of money. And I think combination therapy
- 12:23is quite likely to be that next step, as I would say most of the
- 12:26experts in the field believe that this is kind of likely to
- 12:28be the future. Yeah, nice.
- 12:30And where are you at the things at the moment?
- 12:32You've obviously mentioned you're at the investigators
- 12:35meeting and whatnot. Yeah, walk us through.
- 12:38Yeah. So, so to make a combination it,
- 12:41we think it's a pretty interesting and exciting
- 12:43development path. And we what's unique about Spire
- 12:46is despite kind of the huge players that are in IBD,
- 12:50relatively few actually own all of the best mechanisms in the
- 12:53space. Each of them owns one or two
- 12:55good things and then they're trying to kind of figure out how
- 12:57to do combos with what else they have.
- 13:00I I think we were unique in that we were planning to do this from
- 13:03the outset. And I think we were the only
- 13:06ones that I think own the three best mechanisms in the space
- 13:09with the three that I mentioned. And we own them all on this long
- 13:13acting basis, right? We made these these long acting
- 13:16antibodies and we spent a ton of time over the last few years
- 13:19ensuring that they were that we Co formulate them together so we
- 13:22can put them into a single shot, a single injection, which is not
- 13:26trivial and and not, not certain to do.
- 13:28And also doing kind of combination talks of each of our
- 13:31combinations and proving that they weren't just, you know,
- 13:33we've seen no talks with any of our individual molecules and
- 13:36we've seen no adverse effects even of our combinations dose
- 13:40together as well in a chronic setting.
- 13:42And So what that lets us do is run what I think is one of the
- 13:45more ambitious and exciting trials in the space.
- 13:47It's called a platform trial. I think it's, you know, the
- 13:50first large platform trial in ulcerative colitis where we're
- 13:53testing 6 different interventions in a single study.
- 13:56So this is, you know, 1 placebo, each of those 3 monotherapies,
- 13:59kind of long acting versions of what we think are the best 3
- 14:02targets. And then the three combinations,
- 14:04basically A+, BA plus C and B + C.
- 14:07And we're testing them all in one big study.
- 14:09This is kind of the only way to do this in a robust, rigorous,
- 14:11scientific way to see what works best and do the combinations add
- 14:16substantial value over their individual components.
- 14:19It's a huge initiative. Trial it is, I think it is, I
- 14:22think it's a very exciting trial.
- 14:24I think the physicians in this space are interested in seeing
- 14:26these mechanisms just by themselves compared to each
- 14:29other. And the idea that we can test
- 14:31long acting combinations of what we believe are the best
- 14:34mechanisms in this space is, you know, just potentially not, not
- 14:38an incremental improvement for this field, but a step change
- 14:41we're going from hopefully meaningful improvements in
- 14:43efficacy and at the same time meaningful improvements in
- 14:46convenience in one trial. Yeah, be a big step forward for
- 14:49sure. Yeah, I think it's exciting.
- 14:51So it's a big trial. So we're kind of kicking this
- 14:53off now. It'll be a big global study kind
- 14:55of 30 odd countries participating, a few 100 sites
- 14:58participating in the trial. We've been you know started
- 15:01about six months ago and we'll actually start to read out data
- 15:03from this trial next year, which is so we're going to start
- 15:06reading out the monotherapies first and then we'll follow up
- 15:08with the full combinations against the monotherapies.
- 15:11And I think, I think it's an incredibly exciting time.
- 15:15Not too far away either. No, I mean, no, you know when
- 15:18we, when we started this trial, we thought it would be
- 15:20attractive to physicians and patients because you know the,
- 15:24the efficiency of this design because we only have one placebo
- 15:27arm and six active arms. Most pay, I mean it's about a
- 15:30one in six odds of getting a placebo in this trial.
- 15:33And three of the six active arms are what physicians believe are
- 15:36likely to be the future of this space.
- 15:38And these combination therapies and all of them are more
- 15:41convenient than anything on the market, right.
- 15:43So, so it's, it's kind of a lot of reasons to be excited, a lot
- 15:46of reasons to participate in the trial and I think we're seeing
- 15:48that so far in in the early launch of the study.
- 15:51Yeah, the reason I mentioned it's not too far away is because
- 15:53speed's been a bit of a theme for you over the past, well,
- 15:57decade, I guess. Yeah, that's right.
- 15:58In your career, obviously you mentioned bridge bio when you
- 16:01when you first spoke. And yeah, I guess you've taken
- 16:04some learnings from what those guys were able to achieve.
- 16:06Right. Yeah, I mean, Bridge was a
- 16:09great, I mean, I joined when it was kind of A2 room office place
- 16:12and and, and you know, the company is now now doing
- 16:15incredibly well and got to work with exceptionally talented,
- 16:18hard working folks and saw, you know, a huge number of
- 16:22successes, plenty of challenges too along the way and growing
- 16:24kind of a small company from the outset.
- 16:27I do think one of the learnings that was very obvious now
- 16:30looking back all along the way, we were told, you know, it's
- 16:34going to be really challenging to compete against the larger
- 16:36players in this space. And in particular, one of the
- 16:38lead programs and still probably the most important product there
- 16:41is in a space called TTR cardiomyopathy.
- 16:44And you're competing there against, you know, Pfizer and
- 16:47some of the other largest biopharma companies in the space
- 16:50that, you know, we're both multiple years ahead of us and
- 16:53far better resourced in terms of kind of existing infrastructure
- 16:56to do these trials. And there was a perception that,
- 16:59you know, how can this upstart small company compete in that
- 17:02space? And, you know, I think, I think
- 17:07to be honest, yes. And I think kind of proved that,
- 17:10you know, a small group of folks that are really dedicated and
- 17:12focused on a singular mission and, you know, care deeply about
- 17:17it. I mean, in that trial, I went
- 17:19and visited dozens of the sites to go, you know, shake the hands
- 17:22of the investigators, convinced here's why I'm excited about
- 17:24this drug. Here's how it can help your
- 17:25patients. That is, is something that you
- 17:30that you may not see from the larger organizations.
- 17:32And I think it, I think it matters.
- 17:33I think it pays off in the long run.
- 17:35And I think it, it, it led to some of the successes at Bridge
- 17:38Bio. There was, you know, enrolling
- 17:40that phase three trial there was not trivial.
- 17:42It was during COVID Pfizer drug was launching.
- 17:44There was all sorts of challenges, but being fast,
- 17:47focused and, and caring a lot mattered.
- 17:49And frankly, I take a lot of those learnings into right,
- 17:52we're playing in inflammatory bowel disease.
- 17:54It's a $30 billion commercial market globally.
- 17:58It's J&J, Abby Takeda, some of the biggest players in this
- 18:01space that we're competing against.
- 18:03And, and, you know, it's again, kind of a small company with
- 18:06what I think is an exciting, ambitious approach.
- 18:09And I, I think, you know, being as quick as possible is, is
- 18:12critical to kind of, you know, beating, being more agile is one
- 18:15of the few advantages we have. Obviously, you all in then on
- 18:20that program and you're all in here, right.
- 18:22So I think, yeah, those big pharma businesses are naturally
- 18:26more spread out, right? They're focused.
- 18:27So, yeah, yeah, you go into the trial sites and shaking hands of
- 18:32the investigators, that's not something that's necessarily
- 18:34going to happen in those big businesses, right?
- 18:36Yeah. And I actually think it may be
- 18:38more obvious. We've talked a lot about our
- 18:39inflammatory bowel disease approach.
- 18:41We're actually running a trial in rheumatology as well.
- 18:43And I think it's, I think that might even be a more obvious
- 18:46case where we started working on this TL1A antibody a few years
- 18:50after the first ones were developed.
- 18:51Again, we saw these these first generation TL1A's that were made
- 18:54by a few very successful companies, but saw that, you
- 18:57know, these antibodies were maybe not the best you could
- 18:59make. And so we started making what we
- 19:00thought could be a better one. And and then we're saying, OK,
- 19:03IBD, we're we're quite sure it's going to work in IBD.
- 19:06That's where the data was, was very strong.
- 19:08But this target might work in a bunch of other indications as
- 19:10well, including in these rheumatic diseases, RAPSAX BA
- 19:15that are about the same size as IBD.
- 19:18And the evidence is quite good too.
- 19:20And we thought, look, this, this product could be great there as
- 19:22well in terms of the evidence for it and said, you know, why
- 19:26should we, we should go after this too.
- 19:28Like this product could be a big opportunity there.
- 19:31And frankly, we were surprised to not see the first generation
- 19:33players beat us to it. They probably had a couple year
- 19:36head start again, had all the infrastructure that we didn't
- 19:38have to run trials in different therapeutic areas.
- 19:41And then, you know, we started our trial a few months ago and
- 19:44then within a few weeks thereafter see that those first
- 19:46generation players actually started trials after us in the
- 19:49space. So it's, you know, it, it, it
- 19:52seems unbelievable that you can kind of be an upstart and, and
- 19:55kind of compete against the biggest players.
- 19:56But I, I, I don't think that's the case.
- 19:59I think sometimes you know a a small dedicated group of folks
- 20:02can can matter a lot. Yeah, I guess you're proving it
- 20:05as well. So yeah.
- 20:06Yeah, we'll see. Drugs still have to work.
- 20:08But yeah, I know. But, but I think, you know, in
- 20:10terms of getting the trials off the ground, picking the right
- 20:12indications and and going quickly, I think we've we've
- 20:14shown that we can do that, yeah. No, Awesome.
- 20:16It's gonna be yeah, really cool to watch.
- 20:19Watch the progress from the thought.
- 20:20It's going to be, yeah, really exciting time.
- 20:22Yeah. So we have, yeah, we're going to
- 20:23have six phase two readouts next year, kind of three in the
- 20:26inflammatory bowel disease trial and three in this rheumatic
- 20:29disease trial and followed up with a combination.
- 20:32So I, I think it's gonna be exciting, you know, a few
- 20:35quarters ahead. Yeah.
- 20:36For sure. Awesome.
- 20:37Well, appreciate you coming on. I guess we'll finish with the
- 20:40standard biohopper question. I'm quite excited to get your
- 20:43take on this, actually. It could be an interesting
- 20:45answer. And that's.
- 20:46Yeah. If you were able to have dinner
- 20:48with one entrepreneur or scientist, past or present, who
- 20:51would it be? Yeah.
- 20:52And why? Yeah, so I, my undergrad was in
- 20:55bioengineering and so it kind of fused math, engineering and and
- 20:59biology. And my favorite series of
- 21:02lectures were in a Physiology class that I had that was
- 21:07talking about the experiments done actually here in Cambridge,
- 21:09I think by Hodgkin and Huxley. So they, what they did was they
- 21:13looked at kind of giant squid axons like, and it was because
- 21:17like this is back in the, you know, 30s, forties, 50s, that
- 21:19they were doing these experiments and you, the
- 21:22equipment could only look at something that large.
- 21:24You couldn't look at kind of microscopic things.
- 21:27And they took this really complicated system and, and
- 21:30showed basically how electrical signals are conducted in axons
- 21:35and muscles. And they, they went from this
- 21:38kind of quite brutish experimentation to beautiful
- 21:41maths. So they, they, they have kind of
- 21:43these series of differential equations that describe how
- 21:46electricity is conducted in axons.
- 21:49Beautiful. So, so I would, I would.
- 21:51And they were kind of gentlemen scientists as well.
- 21:53So they kind of did these experiments and then the war
- 21:55broke out. And so they were working, you
- 21:57know, kind of in the war effort as well.
- 21:58So, yeah. I mean, you know, I'm sure 60
- 22:01years later they would be surprised by a lot of things we
- 22:03have today. And I think that'd be a great
- 22:05dinner guest. Yeah.
- 22:06We'll let you off. That's two guys.
- 22:08Well, two guys, yeah, I'll pick one.
- 22:10Hodgkin. Yeah, could be.
- 22:12Either way, it would work, yeah. Thanks for coming on.
- 22:15Coming. Seriously, thanks for having me.
