Latest / Becker’s Healthcare Podcast / The Future of Colorectal Cancer Screening: Reaching the Unscreened
Transcript
- 0:00- Hello, everyone. This is Jacob Emerson with the
- 0:02- Becker's Healthcare Podcast. Thank you so much for
- 0:05- tuning in today where we're gonna be talking
- 0:07- about the future of colorectal cancer screening and
- 0:10- how to reach the unscreened.
- 0:12- Joining me for today's discussion is doctor AmirAli
- 0:15- Talazaz, who is the cofounder and co CEO
- 0:18- of Guardant Health. Doctor Talazaz, thank you so
- 0:21- much for taking the time to be with
- 0:22- me on the podcast today.
- 0:24- Thank you, Jacob, for having me. It it's
- 0:26- great to be with you. Likewise. And before
- 0:29- we dive into everything we wanna talk with
- 0:31- you about today, Emera Lee, can you tell
- 0:33- us a little bit more about yourself,
- 0:36- and a little bit about your role and
- 0:38- what you do today at Garden Health?
- 0:40- Yeah. Sure. So I'm Ira Talasos.
- 0:43- I'm,
- 0:45- one of the founders of Garden Health,
- 0:48- pioneering
- 0:49- liquid biopsy company in the field of clinical
- 0:52- genomics.
- 0:54- We started a company now about fifteen years
- 0:57- ago, you know, with really the mission
- 1:00- of having a simple
- 1:02- routine blood test
- 1:04- that could have
- 1:06- basically guarded the body against this disease. That
- 1:10- was the mission that we have in the
- 1:11- beginning. We didn't know exactly how to do
- 1:14- it, but
- 1:15- fast forward fifteen years after, there are a
- 1:18- lot of great advancements that we've seen in
- 1:20- the field.
- 1:22- I'm also a father of,
- 1:24- three kids with my beautiful wife
- 1:27- and,
- 1:28- you know, trying to do something good for
- 1:30- society and also my family.
- 1:32- Absolutely. Well, let's talk a little bit about
- 1:34- that. Obviously, as you know, Gartner pioneered the
- 1:37- industry
- 1:38- a decade ago with blood based cancer screening
- 1:42- technology.
- 1:43- So talk to our audience a little bit
- 1:45- about what you saw early on that convinced
- 1:47- you that blood could fundamentally change
- 1:51- how we detect and manage cancer?
- 1:55- Yeah. So when we actually
- 1:57- started working in the field and we, like,
- 2:00- pioneered this clinical testing using liquid biopsy
- 2:04- more than a decade ago,
- 2:06- we're driven by this reality that, you know,
- 2:09- cancer is touching
- 2:11- all of us directly,
- 2:13- indirectly.
- 2:15- And more than often, I feel cancer is
- 2:17- being caught far too late.
- 2:19- You know, we realized, in fact, in order
- 2:21- to save lives, similar to other kind of
- 2:24- maybe,
- 2:25- diseases like advancements, for instance, in the cardiovascular,
- 2:30- in order to really add more value,
- 2:33- we needed to make screening tests more effective,
- 2:37- making them more easier for patients to adhere
- 2:40- to and go through,
- 2:42- and really
- 2:43- integrate
- 2:46- pleasant routine screening tests into routine clinical care.
- 2:50- Now if you go back to those earlier
- 2:52- days,
- 2:54- you know, the field of NIPT,
- 2:56- the field of looking at
- 2:58- fetus,
- 3:00- and, you know, through maternal blood
- 3:03- was making very good progress.
- 3:06- The field of next generation sequencing
- 3:09- was making
- 3:10- very good progress. And in theory, if we
- 3:13- could have married running next generation sequencing
- 3:16- technologies
- 3:18- in the blood of cancer patients, we could
- 3:20- have
- 3:22- made significant advancements in the field of oncology.
- 3:25- And unlike the data generation and clinical
- 3:29- insight generation
- 3:31- from these cancer patients where
- 3:34- really the diagnosis
- 3:36- and information
- 3:37- was typically locked in a tumor biopsy sample.
- 3:41- But there were a bunch of technological
- 3:43- challenges.
- 3:44- The accuracy of next generation sequencing
- 3:48- was not at a place
- 3:51- to really detect tiny amounts of fragments which
- 3:54- are coming from the tumors
- 3:56- and was circulating
- 3:57- in the blood of cancer patients. I remember
- 4:01- this field during those days
- 4:03- looked kind of mission impossible.
- 4:05- You know? We were dealing with a lot
- 4:07- of technical challenges. But now
- 4:10- we have a blood test for advanced cancer
- 4:13- patients, which are
- 4:15- routine standard of care. More than thirty percent
- 4:18- of all advanced cancer patients
- 4:20- are getting tested with our blood test, Guardant360,
- 4:24- for their treatment selection. Almost everybody in The
- 4:27- US have access to this blood test.
- 4:31- And more recently,
- 4:33- we are very excited with our shield blood
- 4:36- test.
- 4:37- First, FDA approved Medicare covered blood test for,
- 4:42- cancer screening with the first indication for colorectal
- 4:45- cancer screening.
- 4:47- The shield blood test was really the,
- 4:51- the fruit of ten years of
- 4:54- innovation,
- 4:55- data gathering,
- 4:57- experimental
- 4:58- progress that we,
- 5:01- made, and we leveraged a lot of actually
- 5:04- and recent advancements in the machine learning and
- 5:08- artificial intelligence
- 5:11- to really
- 5:12- build this simple blood test,
- 5:15- which the patient physician experience is very simple
- 5:19- in terms of having a routine blood test,
- 5:21- but with very sophisticated,
- 5:25- algorithm at the back end that we can
- 5:27- find these traces,
- 5:29- tiny traces that are coming from early stages
- 5:32- of the cancer.
- 5:34- So unlike
- 5:36- traditional screening methods, this blood test
- 5:40- can
- 5:41- detect cancers early
- 5:43- with a modality that patients are very used
- 5:46- to. You can count on patients actually
- 5:50- doing it. In real world, we've seen in
- 5:52- over 200,000
- 5:54- shield blood tests that we've done. More than
- 5:57- ninety percent of the patients, when the doctors
- 5:59- ordered this blood test, in fact, go and
- 6:02- complete and get their screening test done,
- 6:05- which is a contrast to some
- 6:08- other modalities that we have that they work
- 6:11- greatly,
- 6:12- but the overall adherence rate of the patient
- 6:15- had remained to be very low. Still, we
- 6:17- have
- 6:19- over fifty million people in United States that
- 6:22- they need to get their colorectal cancer screening
- 6:25- done,
- 6:26- but they are not doing it for different
- 6:28- reason. And now we have a blood test,
- 6:30- which is FDA approved,
- 6:32- covered by some insurancecom,
- 6:34- companies,
- 6:35- and even have a better performance than,
- 6:39- to detect
- 6:40- the disease, the colorectal cancer
- 6:43- disease across all stages
- 6:46- than
- 6:47- published performance
- 6:49- of even gold standard fit test, which is
- 6:52- the,
- 6:54- global leader of
- 6:56- doing colorectal cancer screening. So we are very
- 6:59- excited of the impact that this Shield blood
- 7:02- test can have on the society and bring
- 7:04- health healthier days to patients.
- 7:07- Absolutely. And and, Namiro, you just
- 7:09- hinted at the the persistent,
- 7:12- on screening gaps that still exist. I know
- 7:14- that despite multiple screening options available out there
- 7:17- today,
- 7:18- roughly one in three eligible Americans still remain
- 7:21- on screen.
- 7:22- And, of course, colon cancer rates, we're we're
- 7:24- seeing rise among adults 65
- 7:27- all all across the country.
- 7:29- So why did Guardant
- 7:31- believe that a blood based option could address
- 7:34- this this gap that continues to persist?
- 7:37- Jacob, as you mentioned, you know, there are
- 7:39- already some available option. Like, the gold standard
- 7:42- of colorectal cancer screening continues to be colonoscopy.
- 7:46- We had access to colonoscopy
- 7:48- based screening for, you know,
- 7:51- probably over a decade now. Some stool based
- 7:53- technologies have been around for over a decade,
- 7:56- some over two decades.
- 7:58- So the fundamental issue is not lack of
- 8:02- options.
- 8:04- It's a gap in participations
- 8:06- by patients.
- 8:08- Millions of people are not up to date
- 8:10- with their screening. And we know, in fact,
- 8:13- seventy five percent of all colorectal cancer death
- 8:17- is coming from those people who are not
- 8:19- up to date with their screening.
- 8:22- So the barrier is not really the patients
- 8:25- don't care about their health. You know, some
- 8:27- of that exists, but that's not the main
- 8:29- issue based on the studies that we've done.
- 8:32- Really, the main issue is the current screening
- 8:35- modalities
- 8:36- come with significant frictions
- 8:39- and need significant patient follow through. When we
- 8:43- are thinking about,
- 8:45- you know, special bowel preps, when we are
- 8:47- thinking about people need to get time off
- 8:49- work, they need to find solutions for
- 8:52- right,
- 8:53- you know, to get in or get out
- 8:55- of the procedure,
- 8:57- or
- 8:58- even with stool tests, there's some kind of
- 9:00- a weak factor still that exists in handling
- 9:03- stool samples and, you know, storing stool samples
- 9:07- or shipping those kind of samples.
- 9:09- We those,
- 9:11- tests and modalities
- 9:12- are very effective,
- 9:15- but there is a participation
- 9:16- gap. And now
- 9:18- we have a simple blood test. Like, if
- 9:21- you look at CDC reports, like, there
- 9:23- are, we are finding that, you know, ninety
- 9:26- percent of the patient age 50 and above
- 9:28- are in fact doing some kind of blood
- 9:30- work for some reasons, for wellness checks, annual
- 9:33- checkups, or for monitoring some conditions that they
- 9:37- have.
- 9:38- And now we have this shield blood test
- 9:41- that can just tag along to that routine
- 9:44- blood test
- 9:45- and effectively gives patient,
- 9:48- physicians,
- 9:49- and systems
- 9:51- a new choice,
- 9:53- a new
- 9:54- opportunity, especially
- 9:55- to reach the patients which
- 9:58- they are not participating
- 9:59- in this screening journey right now.
- 10:03- And sometimes, they are not participating
- 10:05- in other kind of clinical pathways.
- 10:08- So we can engage them. We can bring
- 10:10- them to the screening journey.
- 10:12- Hopefully, we can find the cancers at much
- 10:14- earlier stages when they are more treatable, Jacob,
- 10:19- and also bring them back to the clinical
- 10:21- pathway.
- 10:24- Understood. So clearly several major challenges still out
- 10:27- there in in terms of addressing
- 10:29- that that persistent gap merely. But
- 10:33- as you've just explained, Shield has been rapidly
- 10:35- evolving from
- 10:37- emerging technology,
- 10:39- to now being recommended by leading guideline bodies.
- 10:42- You have commercial payer coverage. So talk to
- 10:45- us about what these milestones mean for for
- 10:47- patients, for physicians.
- 10:49- Why is this an important moment for colorectal
- 10:52- cancer screening within the context of of the
- 10:55- challenges that you just laid out for us?
- 10:58- Yeah. We are very excited with these advancements.
- 11:01- And, you know, it's kind of you know,
- 11:02- I'm I'm seeing even with my kids when
- 11:04- they get to some ages that you see
- 11:06- some of the fruit of work and investments
- 11:08- that you've done on them more clearly.
- 11:12- You know, this is something
- 11:14- that was our mission for about fifteen years
- 11:16- and specifically during, like, you know, more than
- 11:19- ten years of r and d work,
- 11:22- finally seeing the fruit of all that advancements.
- 11:25- And frankly, not all the work just by
- 11:28- Guardant held by the whole community of, you
- 11:30- know, other researchers in the field, that now
- 11:33- we are seeing the
- 11:34- clinical impact and adoption that we are seeing.
- 11:38- But definitely, it's very exciting days, you know,
- 11:41- when we are thinking about
- 11:43- NowShield
- 11:44- is f Shield blood test is FDA approved,
- 11:48- covered by Medicare,
- 11:49- covered by some major payers like UnitedHealth
- 11:52- Group,
- 11:53- major guideline bodies like, you know, NCCN
- 11:57- and American Cancer Society
- 12:00- is including shield blood test,
- 12:03- as an option for colorectal cancer screening for
- 12:07- right patient types.
- 12:09- It's very exciting. It came as a result
- 12:12- of, I think, rigorous clinical validations that we've
- 12:16- done. We've showed that it works. The quality
- 12:19- of the test is very good.
- 12:21- And then the real world evidence and the
- 12:24- impact of this test, we've done randomized studies
- 12:27- in some health systems, in some
- 12:30- suburb areas even, in the
- 12:33- some health systems where the overall colorectal cancer
- 12:37- screening rate was forty five to fifty percent.
- 12:41- And then they added Shield as a new
- 12:43- choice, and then
- 12:45- the overall colorectal cancer screening went to high
- 12:48- eighties or low nineties in terms of
- 12:51- percentage of participation
- 12:53- by patients.
- 12:55- It's very exciting to
- 12:57- see and, you know, I think physicians are
- 12:59- very excited about this shield blood test. What
- 13:02- we are seeing is when they see the
- 13:04- performance of this test, the FDA approval,
- 13:08- the sensitivity
- 13:09- of detecting this blood test in early stage
- 13:12- CRC relative to,
- 13:14- you know, published performance by,
- 13:17- other modalities,
- 13:19- they're finding this is the first blood test.
- 13:22- It's the best in the class
- 13:25- that can
- 13:26- really, meet their need.
- 13:28- And when they offer it to their patients,
- 13:32- the follow through by patients is typically even
- 13:35- in the office, in the clinic before they
- 13:37- leave the,
- 13:39- the clinic, the health system, the blood draw
- 13:42- is done. Over ninety percent
- 13:45- of the orders
- 13:47- of the offered test
- 13:49- get converted to getting the actual screening done.
- 13:53- So this is very exciting for
- 13:56- physician and patients right now.
- 13:59- Jacob, actually, when we look at now,
- 14:02- both some of the recent guideline and insurance
- 14:05- coverage,
- 14:06- about seventy million lives out of total of
- 14:08- hundred twenty. So about sixty percent of people
- 14:12- are now covered
- 14:14- to,
- 14:16- get access to shield blood test. Their payer
- 14:18- is actually covering this innovative test. We made
- 14:21- significant progress. Still,
- 14:23- there is a lot of work in front
- 14:24- of us to make sure even the rest
- 14:26- of patient population get equitable access to this
- 14:30- breakthrough technology,
- 14:31- but we are very pleased with where we
- 14:33- are. And
- 14:34- for the patients who are covered by some
- 14:36- private insurance, in fact, vast majority of them
- 14:41- have $0 out of pocket costs to get
- 14:44- access to this chilled blood test. So, really,
- 14:47- like, you know, the conversation has changed, you
- 14:50- know, from,
- 14:51- you know, a blood test for cancer screening
- 14:54- is mission impossible. Like, you know, from ten
- 14:56- years ago to right now,
- 14:59- we have a blood test that it's FDA
- 15:02- approved. Majority of people have access to it,
- 15:05- and really the conversation is now focused
- 15:07- on, you know, what's the responsible
- 15:10- way
- 15:11- to make to
- 15:12- incorporate this blood test and clinical
- 15:15- pathway to make sure we can reach
- 15:17- more people
- 15:19- and
- 15:20- increase the overall screening rate.
- 15:23- And and you mentioned the work, that you're
- 15:25- you're doing with health systems, and we've got
- 15:27- a lot of hospital leaders listening in today
- 15:30- primarily. So
- 15:31- what would you say to those systems who
- 15:34- they're they're working hard to reach their patients
- 15:36- who remain onscreened
- 15:38- despite all the the other options available today?
- 15:41- Where do you see the greatest opportunity,
- 15:44- for our listeners to incorporate more blood based
- 15:48- screening into a comprehensive,
- 15:50- screening strategy?
- 15:52- Yeah. Absolutely. Like, you know, at the end,
- 15:54- 80%
- 15:55- of all the care in US are
- 15:58- provided through the health systems. And for health
- 16:00- system, I think
- 16:02- there's this there's an opportunity, Jacob, for them
- 16:04- to step back and ask,
- 16:07- you know, we had other modality of cancer
- 16:10- screening, colonoscopy
- 16:12- stool based test, But now that we have
- 16:14- this blood test,
- 16:16- what's the best pathway? How could we use
- 16:19- these multiple modalities
- 16:21- in a smart way
- 16:22- in a comprehensive
- 16:24- screening strategy?
- 16:26- And then making sure some of these patients
- 16:29- that have not been connected to the system
- 16:32- now,
- 16:33- we can, in fact, maybe reengage them through
- 16:36- this simple blood test.
- 16:38- The reality is when we are doing shield
- 16:40- blood tests in the onscreen patient population,
- 16:44- a fraction of them, they need to get
- 16:46- follow-up,
- 16:47- diagnostic colonoscopies.
- 16:50- And then that would be an a reengagement
- 16:52- opportunity
- 16:53- for that patient that patient to join back
- 16:55- or come back to that health systems for
- 16:58- all the clinical pathways that that patient needs.
- 17:00- So, I think it's a huge win win
- 17:02- opportunity
- 17:04- for patients and health systems
- 17:07- to start
- 17:08- using this innovative blood test
- 17:11- as a new modality
- 17:14- in a comprehensive menu that they can have.
- 17:17- Our experience actually has shown that physicians and
- 17:20- patients
- 17:21- are gonna have high degree of satisfaction
- 17:25- when they are going through this experience.
- 17:28- So some of the
- 17:30- measures in terms of patient feedback and patient
- 17:34- satisfaction and provider satisfaction,
- 17:38- is gonna be impacted when the patients really
- 17:41- and providers really get access to this innovative
- 17:43- blood test.
- 17:45- Well, in talking about beyond the the blood
- 17:48- test itself,
- 17:49- primarily,
- 17:50- why is it important
- 17:52- for Arden to work with health systems beyond
- 17:54- the test itself to help translate innovation into
- 17:58- a broader population
- 18:00- impact?
- 18:01- Yeah. I think there is this partnership with
- 18:04- between companies like us, Guardant Health, and health
- 18:07- systems are super important and strategic. The the
- 18:11- reality, Jacob, is the impact of Shield blood
- 18:14- test
- 18:16- is way beyond
- 18:17- just the blood draw.
- 18:19- As I mentioned, it's an opportunity to move
- 18:22- that patient through the entire clinical
- 18:25- pathway and an opportunity
- 18:27- to reengage
- 18:28- these on the screen patient population
- 18:32- in their clinical care.
- 18:34- Effectively, maybe we can look at it as,
- 18:37- you know, Shield is just opening
- 18:39- the door. It's the front door.
- 18:43- We are
- 18:44- reaching out to these individuals that previously were
- 18:47- unreachable
- 18:49- and motivating that
- 18:51- motivating those patients
- 18:53- that when, you know, Shield is finding some
- 18:55- kind of a signals in them that they
- 18:58- promptly need to follow through with a diagnostic
- 19:00- colonoscopy
- 19:01- in order to
- 19:03- finish that clinical
- 19:05- pathway
- 19:06- to identify
- 19:07- early stage cancer.
- 19:08- And that would generate a lot of opportunity
- 19:11- for health systems, and we need collaboration with
- 19:14- health system to show
- 19:16- that, in fact,
- 19:18- Shield
- 19:19- can go beyond just detecting something in blood
- 19:23- into really reducing
- 19:25- the cancer mortality
- 19:27- because the patient is sticking through that journey
- 19:30- and going all the way through
- 19:32- the diagnostic colonoscopy and the intervention,
- 19:35- which may be required
- 19:37- after
- 19:38- terms of surgeries or
- 19:40- treatment that the patient needs to go through.
- 19:42- So, effectively,
- 19:45- I think it's a joint opportunity to make
- 19:47- sure we can reengage these on the screening
- 19:49- patients,
- 19:50- not to just
- 19:52- increase the rate of screening,
- 19:54- test. That's very important by itself,
- 19:57- but reconnecting the patient to all diagnostic and
- 20:00- downstream care
- 20:02- that can
- 20:03- get provided by the health system.
- 20:06- So clearly, a lot of exciting developments stalling
- 20:09- the horizon in this space, AmirAli.
- 20:12- I would ask you before we go today,
- 20:14- if you were to look ahead
- 20:16- five years,
- 20:17- what do you hope will be fundamentally different
- 20:20- about colorectal cancer screening? And what would you
- 20:22- also encourage
- 20:23- the health system leaders listening in right now,
- 20:26- how to think differently about all of this
- 20:28- today?
- 20:30- And when we look at actually
- 20:32- the way the pathways work, screening pathways works,
- 20:34- you know, they're essential, but they are not
- 20:36- reaching everyone. You know, we are losing
- 20:39- ends of millions of people like what I
- 20:42- would like to see, like, you know, few
- 20:44- years down the road, and it's beyond the
- 20:46- hope. I'm confident that we could see it
- 20:49- if we have strong private public partnerships.
- 20:52- We can reach to a point that
- 20:55- overall mortality of colorectal cancer could go down
- 20:58- further,
- 20:59- especially for younger patients now.
- 21:03- In colorectal cancer is becoming number one cancer
- 21:06- related killer in United States,
- 21:09- and we can really change that trajectory by
- 21:12- making sure we can prevent cancer mortality
- 21:15- by detecting it early through really a comprehensive
- 21:18- screening program and adding this innovative blood test
- 21:21- as a new option.
- 21:23- So I think success
- 21:26- is
- 21:27- not gonna be defined as just
- 21:30- shield blood test is waning, as single modality
- 21:33- is waning, but really success would be
- 21:36- we can bring more and more patients around
- 21:40- the table,
- 21:41- engage them,
- 21:42- screen them for cancer,
- 21:44- detect those cancers early, especially in the rural
- 21:48- underserved communities.
- 21:50- And I think that fatty shield blood test
- 21:52- can do its its own contribution.
- 21:54- But we need very strong
- 21:56- partnerships.
- 21:57- We are in the early innings of
- 22:00- some very exciting conversations
- 22:03- with few dozen health systems as we speak.
- 22:06- So I'm
- 22:08- confident about what we can do together, but
- 22:10- there is work in in work in front
- 22:13- of us.
- 22:15- Absolutely. Well, doctor Talzaz,
