Latest / CareTalk: Healthcare. Unfiltered. / Can Personalized Medicine Live Up To It's Potential?
Transcript
- 0:00Everyone wants care, specifically Caleb DeBam, and that's the promise of personalized medicine.
- 0:05There's technologies like genomic sequencing, biogymatics, gene editing, and AI that are making personalized medicine possible, but we're really still in the early phase.
- 0:15So what is the potential of personalized medicine, and how soon will we see the results?
- 0:27Welcome to Care Talk, America's home for incisive debate about healthcare business and policy.
- 0:32I'm David Williams, president of Health Business Group.
- 0:35And I'm John Driscoll of Presby Walgreens Health.
- 0:38Join the ever -growing Care Talk community on LinkedIn, where you can dig deep into healthcare business and policy topics, access Care Talk content, and interact with the host.
- 0:47Now we don't really have a personalized version of it yet, but John, maybe that'll be sure next time.
- 0:51David, let's start with, what is all the buzz about?
- 0:56personalized medicine, what is it?
- 0:58And is it in any way relevant to patients and families today?
- 1:05It is relevant.
- 1:06Let me say what it is.
- 1:06So it's really about tailoring medical treatments to the individual characteristics, conditions and preferences.
- 1:13And the contrast is we're going from the one size fits all medicine to personalized approaches.
- 1:18And then one size fits all is because the study and it will say, okay, blood pressure should be this, or this is how you treat this and all this.
- 1:26And it's based on real data and real studies by the tendency to sort of give you the average result.
- 1:32And that's what you're hearing.
- 1:33So personalized medicine is getting down to the specifics for you as an individual, your treatment decisions.
- 1:41And there's a lot of technologies that are underlying it.
- 1:45Yeah.
- 1:45I think the context here though is important from the Watson and Crick identification of the interlinking of DNA and RNA and identifying.
- 1:56what was hopefully almost a map or a topography of biology, there's been this promise from the fifties and sixties that, gosh, if we could really understand in almost a mechanistic way how different genes express, which are deeply unique, and we currently care for both through drugs and general therapy, broad categories of people, we could unlock some secrets of health.
- 2:25We mapped the genome and so there's a genomic Atlas, if you will.
- 2:30So we got that mapping correctly.
- 2:31Yeah.
- 2:32Which is a big deal, John.
- 2:33And that took 13 years and it finished 20 years ago.
- 2:36And I think people thought, okay, now we have everything, but it shows just the amount of complexity actually interpret that map once we have found the map.
- 2:44And, but then we found that it isn't just the genes themselves and how they interact, but there's epigenetics and then the epigenetics.
- 2:53which is how they're expressing.
- 2:56Then we realized that there's a level of complexity around proteins.
- 2:59And so to some degree, we're sort of starting with the, the, the end view of personalized starts with, okay, one map, then you get one more level deeper and one more level deeper and one more level deeper.
- 3:09And at each level, it feels like people have promised that personalized medicine is going to transform care primarily in, in, on the biopharmaceutical side where we can actually target therapies to specific diseases.
- 3:22We should get into that.
- 3:23But I think to be fair, David, like a lot of early stage technologies that have grand promise that the grand promises were made early before we actually could make great progress.
- 3:35And maybe we could talk a little bit about kind of how it's being applied today and or misapplied so that people can kind of put it in a personalized medicine or personal context.
- 3:45Exactly.
- 3:46Let's hear John.
- 3:47So.
- 3:48You know, I get kept a little bit in your comments, the sense that, hey, the more questions we answer them, the more questions we ask.
- 3:54And that is true to a certain extent, but let's say there was the map and maybe, you know, in order to sell the idea of the human genome project, uh, you needed to say it's going to do all these great things.
- 4:04Otherwise you're not going to raise all the money for it.
- 4:06So that's there.
- 4:07Uh, and maybe that's just a little bit into the future.
- 4:09There is this thing called the all of us research program, which is actually the attempt to get a million individuals across the country and various diverse.
- 4:18demagoguities in order to understand what all this genetic information means.
- 4:24And they have a report that just came out and they've identified more than 275 million seriously unreported genetic variations.
- 4:32And there's about four million of those that have potential health consequences.
- 4:35So on the one hand, we're going deeper and deeper into asking the questions.
- 4:38On the other hand, I know you're getting to the point about like, does this need any?
- 4:41Let me give a couple of examples where there is actually specific benefits that are being held now.
- 4:46So one is certainly, Uh, mutations, bracket one and bracket two are well known, uh, that lead, you know, with very directly, very high chances to have that she can get breast cancer or ovarian cancer.
- 4:57And so.
- 4:58Although it's not something that people want to do.
- 5:01Um, you know, the people that have mastectomies and, uh, they have the ovaries and low P, uh, to remove, to prevent cancers.
- 5:08That's actually happening.
- 5:09Gene editing is happening for this.
- 5:11I mean, just, just to be clear, that is a genetic polymorphism, a genetic difference.
- 5:17that you can identify through a test.
- 5:20And I think it's like one out of three or one out of four women will have some form of breast cancer in their lives.
- 5:25So it's a very common form of cancer for women.
- 5:28And the specific cancers related to that genetic variation can be targeted with either direct therapy or surgery and save lives.
- 5:38So that's a great example of where by providing the map, we've identified the target.
- 5:43The target is tied to illness and we've actually got a solution.
- 5:47surgery and, and drugs to, to deal with what would otherwise be an incredibly lethal form of cancer.
- 5:54That's right.
- 5:55And that isn't the only example.
- 5:56So there's, we have CRISPR you might've heard about, which is about gene editing.
- 6:00So like directly editing a gene, uh, and for sickle cell disease, there's actually, if we could back up a second David, because I do think that when you think about it, I remember, uh, your buddy, Bill Clinton was on the, on the, on the, on the White House lawn with Craig Mentner and talking with the private sector, Dr.
- 6:19Craig Mentner, we've mapped the genome in the nineties and now we're going to unlock all of these diseases.
- 6:26Well, the reality is that the unlocking has taken a long time, but now we're getting to the point where we can not only unlock and identify BRCA1, BRCA2 specific genetic variations that lead to treatment, but CRISPR is actually a software like technology.
- 6:44that allows us, once we understand what that genetic polymorphism or difference is, that we could potentially use that technology and manipulate people's biology so that they could heal themselves.
- 6:59These are called targeted therapies and they're remarkable and CRISPR is probably as an acceleration of those targeted therapies because we literally can theoretically manipulate people's biology directly.
- 7:14to save lives.
- 7:15So we get, you know, and yes, save lives, but potentially to do other things too, right?
- 7:19Which is where some of the concerns come in.
- 7:22So if you think about Christopher gene editing for something like, you know, sickle cell disease, where you can make an edit and essentially cure at least certain people, sickle cell, that's great.
- 7:30That's kind of like a cell checker.
- 7:32And you're going to say, oh, there's a typo.
- 7:34I'm going to fix that.
- 7:36Now the thing with gene editing, you might also just type a whole new sentence and that may lead us into different, uh, different directions.
- 7:42A couple of other examples.
- 7:43So.
- 7:44Uh, CAR -T, which is a type of the neuro therapy, uh, where we actually genetically engineered T cells of the patients.
- 7:50And that could be used essentially to train individual cells to attack certain cancers, leukemia and lymphoma in particular.
- 7:58And then beyond some of those, some things that are purely on the software side, it was an example of hacking the continuous glucose monitor in order to allow personalized treatment and adjustment for insulin.
- 8:10And that's actually.
- 8:12grassroots open source project was done.
- 8:14So there are real examples, John.
- 8:15Let's get to that one later, but I just really want...
- 8:20I mean, these are...
- 8:22I think it goes back to that...
- 8:24What I'm reminded of is the Bill Gates quote that we tend to overestimate initially the impact of technology in the next two years and underestimate the impact in 10.
- 8:34CRISPR and targeted immunotherapies literally...
- 8:39permit the manipulation of biology for, to create a potentially better outcome.
- 8:44There are, there are the sickle cell diseased disproportionately hits people of color.
- 8:50And it is genetic and it is a genetic variation that we can potentially reverse targeted immunotherapies where we actually use the equivalent of bio biological weapons to attack different forms of cancer.
- 9:06Skin cancer would be another one.
- 9:08The CAR -Ts are, you know, leveraging T cells, which are these incredibly powerful pluripotential cells in the body to overwhelm, if you will, the cancer and accelerate in almost a superpower -like way dealing within patients' bodies.
- 9:27So 20 or 30 years in, after we've talked about the map, we're actually finding ways for delivery vehicles for curative therapy.
- 9:36The risk here, the reason why the FDA has been slow to approve this stuff is if you get it right, you can kill people because you're literally manipulating their biology.
- 9:45So initially a lot of the research was done on people who were desperately ill and near death anyways.
- 9:52And there have been cases for older people to babies where these targeted biological therapies based on personalized medicine or leveraging the insights we have from your personal DNA.
- 10:04your personal biological makeup to create curative therapies.
- 10:08But David is, it sounds like, you know, the, what would have been thought of as science fiction 20 or 30 years ago, and we're going to cure everybody.
- 10:17Like what, what could possibly go wrong here?
- 10:19Yeah.
- 10:19Well, John, before we think about what could go wrong, cause I think that's, you know, there's a lot that could go wrong, but we're talking about, okay, the great promise into the future.
- 10:28And your point about things being overestimated in the near term and then underestimated in the long term.
- 10:33One of the reasons for that is that these technologies don't exist in a vacuum.
- 10:38And when multiple things come together, they can be combined in new ways.
- 10:42One way to think about that is maybe with something like a smartphone.
- 10:46Right?
- 10:46So it's just a phone, but it should combine the ability to make phone calls with the ability to track, uh, location and then to have video and to have computer processing all in one place.
- 10:58Now you can do all sorts of things completely, really invented like ride sharing never would have been just done with a, with a phone, but you actually need all of those different moments to come together.
- 11:07Think about that similarly as it relates to personalized medicine.
- 11:10So there's an example here that's just starting out called a concept of a virtual twin.
- 11:16So psychiatric disorders have been the hardest, some of the hardest things to actually understand it to cure.
- 11:22But if you combine the possibility of, you know, the genome mapping.
- 11:25the analysis with big data and AI, and then the possibility of doing simulation, you can actually create essentially computerized version that's a match, whether somebody's brain and you can do simulations there in a way that you could never do ethically with an individual person.
- 11:41And you can actually design our therapies for that.
- 11:44Those sorts of things, putting different technologies together, we're going to see the big impact, I believe.
- 11:49Yeah.
- 11:49Yeah.
- 11:50I think we should approach the personalized medicine, the broadest aspect of the categories.
- 11:54tied to, the most exciting ones are the ones that tie to biology and biopharmaceuticals.
- 11:59But when you step back and you realize that we use very generalized rules in general for dosing or prescription or for physical therapy, we realize that everybody's a little bit different.
- 12:10You start to step back and say, like, you know, my, my wife's involved in a personalized food program where she's leveraging diet, food, and behavior change to help people really change the arc of their health.
- 12:23But they start with.
- 12:24a really tight assessment on how and why and where do people eat right now?
- 12:29What is their cultural tradition?
- 12:31How do they think about food?
- 12:33Do they use it for entertainment?
- 12:35Is it income restricted?
- 12:37And by really understanding why people eat the way they eat, particularly those who are suffering from diet -sensitive chronic disease, you can't just tell people to eat more salad.
- 12:48That doesn't work.
- 12:49You need to go dial back to their personal home, family, culture, neighborhood.
- 12:54access traditions and kind of what they use food for.
- 12:57And that actually they've had some incredible results without mapping anybody's genome or trying to understand how their proteins express.
- 13:05And I think in mental health, very similarly, one of the things that's interesting is the ability to use big data tools, which is to say we've got access to lots more data.
- 13:14We can leverage much more powerful compute and perhaps some artificial intelligence to actually look at, okay, David.
- 13:22How do I help you manage your anxiety disorder?
- 13:25Because you're different than your brothers.
- 13:28Thanks for your health, John.
- 13:29And your, your anxiety sorts tied to your care talk projects, but doing, doing what I can.
- 13:35Again, family culture background is requires a lot more data.
- 13:39It's not like you do biology, but I think that would help my therapist figure out my challenges.
- 13:44Uh, I think it's really thinking about leveraging all of these technology tools to make sure that the general.
- 13:51recommendations are personalized to my specific problems, challenges, and opportunities.
- 13:56But I do think we're at the dawn of a different age and it's this divergence of biological tools, biological data and insights and big compute.
- 14:06Let me close out by following up on your, on your piece about the broader person and then also new technologies and new frontiers.
- 14:14So, uh, if you read the sociology journals, which I generally don't, but I did in preparation for this and understand what's the, what's the critique of.
- 14:21personalized medicine.
- 14:22So the concern is that we should kind of call it biological reductions.
- 14:27First, like, Hey, everything is taken down to your genes.
- 14:30And we're just going to engineer you and personalize it.
- 14:33You know, you lose all the context that you're describing.
- 14:35So that's on the one hand.
- 14:36So we need to bring that balance back on the other hand.
- 14:39Uh, you know, once we go beyond the genome, then there's the microbiome, which is all what lives in your, in your guts.
- 14:46And it's much more complicated.
- 14:48Um, actually then the, then the genome, but has this, uh, found locations that you do see companies, um, that are actually combining a microbiome and AI to understand what that means on a personalized basis.
- 15:00So where to come John's what I would say.
- 15:02I am less interested in exploring your gut and more in the general categories here, David.
- 15:07Sorry.
- 15:08All right.
- 15:08So you're interested in my, I'm losing track here.
- 15:10You're interested in my, my gut DOA and in my brain chemistry.
- 15:14In any case, that's it for yet another episode of Pure Chocolate, the talk today about personalized medicine.
- 15:20I'm David Williams, president of Health Wizard's Group.
