Transcript
- 0:03hey everybody
- 0:03welcome back to the Eye Believe Podcast
- 0:05I'm so glad you guys could join us today
- 0:07and we're bringing back one of our most popular guests
- 0:10from the beginning of when I started doing the podcast
- 0:12this is Dr. Justin Moser
- 0:13a lot of you guys have uh
- 0:14showed up in his clinic and said uh
- 0:16this is this is Danet's doctor right
- 0:19um so
- 0:20we are so glad
- 0:21that he's willing to be a guest on the podcast
- 0:22and just for his expertise
- 0:23and his continued research in
- 0:25in the field of ocular melanoma
- 0:27um but
- 0:28he's a medical oncologist
- 0:29at the Honor Health Research Institute in Arizona
- 0:32and today
- 0:33we're going to be chatting about the Insight Biobank
- 0:35um so I don't really know a whole lot about this
- 0:38so Justin
- 0:39do you want to give us a little bit of a rundown
- 0:40like what is the Biobank
- 0:41and why do we feel like it's super important right now
- 0:44yeah absolutely
- 0:45so first of all
- 0:45thanks for the introduction and thanks for having me
- 0:48um so a biobank
- 0:49to start is really an area
- 0:52or it's a process where we collect biospecimens
- 0:55so that could be samples from patients
- 0:57so that could be blood tissue
- 0:59you know vitreal fluid from the eye
- 1:01really anything and the goal of the
- 1:03of a biobank is to collect tissue from enough patients
- 1:06that we can collectively
- 1:07look and understand the disease
- 1:09these are really important for rare tumors
- 1:11like uveal melanoma because really
- 1:14to understand how a cancer works
- 1:17you typically need a lot of samples sometimes
- 1:19you know hundreds
- 1:21sometimes if not thousands of samples
- 1:22and when you have a disease
- 1:23that's as rare as uveal melanoma
- 1:26we need to to get the number of samples needed
- 1:28to truly understand it and therefore
- 1:31truly treat it
- 1:32we need to collectively get samples as a big group
- 1:35because no one institution
- 1:36can ever collect enough samples themselves
- 1:39I feel like that totally makes sense
- 1:40and I I feel like this is something that
- 1:42even from the time that I was originally diagnosed
- 1:44almost six years ago
- 1:45that I've heard kind of noise in the community about
- 1:47like oh
- 1:48like we need to bank tissue
- 1:49we need to be able to research like
- 1:51and I think I had like a
- 1:53you know the Castle bio or the Castle biopsy was
- 1:55was the the decision next for uveal melanoma
- 1:58and I I remember asking or like
- 2:00learning about how like
- 2:01that sample that little teeny
- 2:03tiny little like
- 2:03needle biopsy that they do
- 2:05that they store an extra bit of that sample
- 2:07and I was like oh well
- 2:08like what can we do with that
- 2:10the biobank sounds like that would be something
- 2:12you know that
- 2:13that it could be used in um
- 2:14or you know
- 2:15not necessarily that sample specifically
- 2:17but just you know
- 2:18when there are extra samples from a biopsy
- 2:20whether it's from the eye or somewhere else
- 2:22um that
- 2:22that would be helpful so like
- 2:25where where was kind of the
- 2:27the brainchild and like
- 2:28the vision for creating the Insight Biobank
- 2:30specifically yeah
- 2:32I think the cool
- 2:32unique thing about the Insight Biobank is
- 2:34it's really driven by A Cure In Sight
- 2:36it was really a patient driven thing
- 2:38and a couple years ago A Cure In Sight led an effort of
- 2:42you know trying to get a bunch of institutions together
- 2:44to create a biobank and one of the barriers we had
- 2:47which is one of the barriers we have
- 2:49with all institutional biobanks
- 2:51is getting if institutions are involved
- 2:55then it's hard to get agreements
- 2:57on how the tissue can be used
- 2:58who owns the tissue who makes the deciding factors
- 3:01and so A Cure In Sight really led by Melody
- 3:03the president you know
- 3:05spent a long time
- 3:05trying to figure out how to get around this
- 3:07and she's really the brainchild
- 3:09and the person who got this up and running
- 3:11where
- 3:12the Insight Biobank is really a patient driven biobank
- 3:15so instead of institutions coming to you and saying um
- 3:19you as a patient saying you're gonna get a procedure
- 3:22can we take extra tissue
- 3:23it's really A Cure In Sight messaging to the patients
- 3:26and the patients going to their providers saying
- 3:28I want to contribute extra tissue to this
- 3:31and then you know
- 3:32kits are sent to the patient or to their surgeon
- 3:35to their interventional radiologist
- 3:36and it goes to the patient
- 3:37run biobank to make sure that it is patient run
- 3:41you know it is governed by a group of individuals
- 3:43including a couple of medical oncologists like myself
- 3:47a couple of ocular oncologists
- 3:49we have pathologists we have patient advocates
- 3:52and we have people from A Cure In Sight
- 3:53to make sure that we're allowing
- 3:57you know
- 3:57the samples to be used to push the science forward
- 4:00but also in a responsible way
- 4:01if patients are gonna donate tissue
- 4:03and donate their time to contribute to the biobank
- 4:06we wanna make sure one
- 4:09that we can actually get the tissue out
- 4:11to people who want it and have a good idea
- 4:13but we're also only using that tissue
- 4:15for stuff that's gonna move the field forward
- 4:18yeah that makes sense
- 4:19like we wanna
- 4:21we wanna make sure it's used judiciously
- 4:23ha ha um
- 4:25so alright
- 4:25so a biobank like you said it
- 4:28it exists to help kind of
- 4:29try to answer some of these research questions
- 4:31in fields that are more rare
- 4:34uveal melanoma we know
- 4:35has been notoriously difficult to get
- 4:38like large scale movement forward
- 4:40and obviously in the last five or so years
- 4:42we've seen some really good jumps in research
- 4:45in clinical trials but
- 4:46what research questions have still kind of
- 4:48continued to be difficult or hard to answer
- 4:51without a resource like this biobank
- 4:54yeah a lot of it comes down to just
- 4:56what is the biology of uveal melanoma
- 4:58right we know that 96% or so
- 5:01of uveal melanomas are driven by mutations in GNAQ
- 5:03or GNA11 um
- 5:06but what that actually changes
- 5:08and what downstream proteins and signaling
- 5:11you know that actually are
- 5:13are subsequent to that that actually drive the cancer
- 5:16we don't fully understand
- 5:18and really to design a drug to treat a cancer
- 5:22you have to intimately know the biology of that cancer
- 5:25we need to know what proteins
- 5:26what DNA what RNA
- 5:29what are the essential drivers
- 5:31that may be upstream or downstream
- 5:32of the GNAQ or 11 mutation
- 5:35that are potent and selective enough
- 5:37that if we turn it off or target it
- 5:38it'll shut down the entire system
- 5:41and that's where um
- 5:43you know having this tissue can be really helpful
- 5:45now there's other ways we can do this
- 5:46like mouse studies and using patient derived cell lines
- 5:51however patient derived cell lines are not always 100%
- 5:55um
- 5:56uh they can change and evolve over time
- 5:59so doing sequencing on a cell line
- 6:00that's been around for 10 years
- 6:02may give you some different information
- 6:03than doing sequencing from a patient biopsy
- 6:06those are very different things
- 6:08and then you know
- 6:09in mouse models sometimes
- 6:10we can probe biology and change stuff here and there
- 6:13but mice are not humans and
- 6:15although they're tremendously helpful
- 6:17to helping us understand biology
- 6:19and moving cancer science forward
- 6:21they also have their limitations
- 6:23and so
- 6:23the best way to design new cancer drugs for patients
- 6:28is to understand the biology of patients
- 6:30and to do that we need samples from patients
- 6:33yeah that makes sense
- 6:35um and I
- 6:36I know like
- 6:36as a patient you know
- 6:38some of the the things that people in the community
- 6:40especially when you are in the
- 6:42you know in the metastatic world
- 6:43some of those big questions that come around is like
- 6:45well like
- 6:46I'm say like a
- 6:48supposed to have been a lower risk patient
- 6:50right like
- 6:51and I'm I'm not speaking of myself
- 6:53I'm just hypothetically um
- 6:55talking about some patients who were told
- 6:57oh yeah
- 6:57your biopsy from your eye
- 6:59looked like you were gonna be lower risk
- 7:00and then boom seven
- 7:02eight years later they're metastatic
- 7:04and it's like whoa
- 7:05like I wasn't expecting that
- 7:06so hopefully some you know
- 7:08some of the research that
- 7:09that comes around and that we can
- 7:11kind of gather all these samples in the biobank
- 7:12hopefully we're able to understand better why
- 7:15why does that happen um
- 7:17exactly and that's some of the things
- 7:19you know we've already started to see that a little bit
- 7:21but there's still a long way to go right
- 7:22we know
- 7:23SF3B1 mutations typically are lower risk
- 7:26but they also make you higher risk
- 7:28for having late relapses 7
- 7:308 years if not 14 years down the road
- 7:32like you mentioned and so initially
- 7:34when we understood uveal melanoma
- 7:35we thought it was just low risk
- 7:37high risk now we know it's low risk
- 7:40high risk with or without prame
- 7:42we know low risk with SF3B1
- 7:44SF3B1 is different than not
- 7:45and so
- 7:46it's using these tissues to develop more information
- 7:49to better refine all the tools
- 7:51and treatments that we have
- 7:53yeah absolutely
- 7:54um what
- 7:56I mean just like hypothetically
- 7:57like where
- 7:57would you love to see the research from the biobank
- 8:01kind of influence
- 8:02um like
- 8:03the development of clinical trials or like
- 8:05the use of treatments in the patient
- 8:07like kind of journey of metastatic disease specifically
- 8:11yeah
- 8:12I think there's many ways we could utilize a biobank
- 8:14you know
- 8:14one of the things we're seeing in oncology right now
- 8:16is an explosion of drug
- 8:18antibody conjugates and t cell engagers
- 8:21and what these things are
- 8:23is there molecules that bind to a protein
- 8:25on the surface of a cancer cell
- 8:28and on the back
- 8:29so one part of the molecule binds the cancer cell
- 8:31the other part has a payload
- 8:33which is usually a chemotherapy
- 8:35or sometimes an immunotherapy
- 8:37or sometimes a targeted therapy
- 8:38so it's a way of selectively delivering cancer therapy
- 8:41straight to tumors
- 8:43but you do you have to know
- 8:45what protein is expressed on that tumor
- 8:47and we know this very well in stuff like breast cancer
- 8:49where we see HER2 activation all the time
- 8:52um and
- 8:54you know there's a lot of these coming out
- 8:56and so one thing we could do with the biobank is
- 8:58if we collect enough tissue
- 8:59we could actually look to see
- 9:01do uveal melanomas express any of these targets
- 9:05that these drug
- 9:05antibody conjugates are targeting right now
- 9:07and can we repurpose
- 9:08and pull some of those drugs from development
- 9:12into other cancers into uveal melanoma as well
- 9:16the other thing we can do is really just try to
- 9:18try to find new targets ourselves
- 9:20you know
- 9:21the technology for understanding biology is exploding
- 9:24right now it used to be that we could test for
- 9:27you know we could sequence DNA
- 9:29then we could sequence RNA
- 9:31then we could sequence whole exome
- 9:33a whole genome DNA and now we can sequence
- 9:36you know link RNA
- 9:36and micro array and proteomics and phosphoproteomics
- 9:40and all of these things you know
- 9:43can could tell us the story
- 9:45and putting them all together may be more important
- 9:47because we always like to think that
- 9:49if you have a mutation in DNA
- 9:52that cut is transcribed into RNA
- 9:53which is transcribed into a protein
- 9:55but really it's more complex than that
- 9:57you can get DNA going to RNA
- 10:00but something could knock it down
- 10:02and prevent that RNA from becoming a protein
- 10:04you could make it a protein
- 10:06but then you could get degradation of that protein
- 10:08or phosphorylation
- 10:09or some other modification that shuts it down
- 10:12and so really
- 10:14using samples to kind of look at the complete biology
- 10:17from start to finish
- 10:18is what's most likely to give us the insight
- 10:21of how to treat this disease
- 10:22now that's very hard to
- 10:23do you need very good biostatisticians
- 10:26very good data scientists
- 10:28and very good um
- 10:29sequencing and multiplexing technologies
- 10:31but those are coming
- 10:32we're starting to see those enter the clinic
- 10:34and be more and more useful
- 11:07yeah I mean
- 11:08it all sounds like there's
- 11:09there's so many pieces of the science
- 11:11that I definitely don't think that I'm like
- 11:13fully grasping but I love what you said about how it
- 11:16the idea is to help tell the story right
- 11:18we're trying to fill in the gaps exactly
- 11:22okay so
- 11:24um I wanna chat a little bit about
- 11:27like we have
- 11:28at A Cure In Sight
- 11:29if you guys have been around
- 11:30you know we have a couple of registries
- 11:32or I guess we have a registry
- 11:34and then we have the Biobank
- 11:35and I wanna I wanna see if we can kind of
- 11:37differentiate between the two
- 11:39and just kind of explain why both are important
- 11:41um because we do have the Insight Registry
- 11:44but this is the Insight Biobank
- 11:45so why do you think like
- 11:47as a as a clinician
- 11:48as a researcher yourself
- 11:49why do you think that it's important
- 11:51to have both of these
- 11:52we've got the Natural History Registry plus a biobank
- 11:56yeah it's important
- 11:56because they help us answer different questions
- 11:59and the biggest power comes from linking the two
- 12:01so
- 12:02having the registry that allows us to answer questions
- 12:04like is there clustering in families of uveal melanoma
- 12:08and if that's the case is it genetic
- 12:10is it environmental it helps to tell us
- 12:13you know is there
- 12:14or it helps us to identify
- 12:15is there a subgroup of patients who are quote
- 12:17low risk like you mentioned
- 12:19but um
- 12:20still end up getting metastatic disease or vice versa
- 12:23people who are high risk and those who don't
- 12:25and that really so
- 12:26the registry helps us answer those type of questions
- 12:30on a population patient level
- 12:32the Biobank really helps us answer the questions
- 12:35on the molecular biology level
- 12:37now if we compare the two and say
- 12:40you know learn about the biology of someone's tumor
- 12:43and then link it to the registry and say
- 12:45you know
- 12:46this person was actually one of the high risk people
- 12:49that never actually developed metastatic disease
- 12:52we can then try looking and saying
- 12:54what
- 12:54in their biology is unique compared to those who did
- 12:58and that can provide valuable insights into what can we
- 13:01how can we potentially
- 13:02try manipulating other people's tumors
- 13:04to turn them from high risk metastasis
- 13:07to low risk metastasis so they're both very important
- 13:10cause they answer both questions
- 13:12or they answer separate questions
- 13:13but they're merging them together
- 13:15brings us the most power and ability
- 13:17to really
- 13:18try to make an impact in treating uveal melanoma
- 13:23wow no
- 13:24that's like I mean I
- 13:25I think that is kind of a
- 13:28just like the most crazy part of the
- 13:30the research world that I think exists
- 13:32is this idea that we're trying to
- 13:34to piece together all the puzzle
- 13:36and not just like
- 13:37using like
- 13:37one piece of it like
- 13:38we gotta we gotta pull in the natural history
- 13:40we gotta talk about
- 13:42what is the patient actually experiencing
- 13:44even though you know
- 13:45maybe statistically
- 13:46they were supposed to behave a certain way
- 13:48um so as we're like
- 13:51looking into the future like
- 13:52the Biobank has only been around for a short time
- 13:55um
- 13:56like what do you feel like
- 13:58success looks like for the Insight Biobank 5
- 14:0010 years from now
- 14:02yeah you're right
- 14:03it's really been around just a short time
- 14:05I think
- 14:05we really only started collecting a couple months ago
- 14:08and I think you know
- 14:09success is gonna come in waves
- 14:10obviously to answer the scientific
- 14:12or to start asking the scientific questions
- 14:15we need the tissue to look at
- 14:16so step one is
- 14:17really getting the messaging out about the biobanks
- 14:20and hope that patients you know
- 14:21are are willing to talk to their surgeon
- 14:25their um
- 14:26interventional radiologist who's doing the biopsy
- 14:28wherever it is in the US say hey
- 14:30I would like to donate my samples
- 14:32you know it's a very easy process
- 14:34the biobank will ship samples to them
- 14:36they just simply ship it back
- 14:37it's very easy um
- 14:39but really I think the near term success
- 14:41is getting the message out
- 14:42and starting to get samples collected
- 14:44and then it's on us as the biobank
- 14:46to start engaging with researchers
- 14:48and letting them know
- 14:49this is the resource that the patients have developed
- 14:52and contributed and this is open in public
- 14:55so how can we answer the best questions
- 14:57and then
- 14:58getting the researchers to know this is available
- 15:01so they can start designing those questions
- 15:03and then start doing our first studies
- 15:05the other thing that we're trying to do
- 15:07is partner with researchers
- 15:09who've already discovered something
- 15:11and maybe have an idea but need more samples
- 15:13so one of our initial collaborations
- 15:15was working with Doctor Hawk
- 15:17who needed some extra samples
- 15:19and so we put out a blast saying hey
- 15:20do you have tissue that can do this
- 15:23are are you someone who
- 15:24you know progressed on this drug
- 15:25and do you have samples that you're willing to share
- 15:28and I think that can be really powerful too
- 15:30because that just speeds it up
- 15:32you know if a researcher has an idea
- 15:34or a hit on something
- 15:35that they think could be used to treat uveal melanoma
- 15:39they can either collect the samples themselves
- 15:41which could take a couple years
- 15:42but if we can partner with them and speed it up
- 15:44that's just gonna get new treatments
- 15:46new science to patients quicker
- 15:48and that's really our goal
- 15:49getting stuff to patients quicker
- 15:51so I think
- 15:52one of the challenging things that patients face
- 15:54especially when we're diagnosed
- 15:56is realizing just how rare ocular melanoma is
- 15:59and then you know
- 16:00even in the metastatic world
- 16:01like seeing how challenging it can be
- 16:03to treat that can be really discouraging
- 16:05um and I think that a lot of patients sometimes wonder
- 16:08like you know
- 16:09can I actually make a difference right
- 16:10I'm just one person um
- 16:12could my tissue really make a difference
- 16:13so I love like
- 16:14hearing what you said about how
- 16:16if a researcher has a specific question
- 16:18that they can get answered
- 16:19like we can um
- 16:21like the biobank can kind of put out a call right
- 16:24and say like
- 16:24we need tissue for this reason
- 16:26and then I I guess
- 16:27as a patient like
- 16:28that just makes me feel like okay
- 16:30like it's not just going to sit in the Biobank
- 16:32like it has a direction right
- 16:34it has a specific direction of what it's going to do
- 16:36and who's gonna use it and why
- 16:38um and I think that just knowing that the
- 16:41the whole purpose of the biobank is to drive
- 16:45you know research in that kind of a way
- 16:47like actionable research
- 16:48things that are gonna move the needle forward
- 16:51that makes a really big difference for like
- 16:52why would I want to donate my sample
- 16:54because I think
- 16:55I think that some of it probably comes down to like
- 16:58a lack of understanding of how this works and be
- 17:00and maybe even like you said
- 17:01being nervous to like
- 17:02ask the the doctor who's doing the biopsy hey
- 17:05I'd like an extra sample um
- 17:07so I guess for those people who are like
- 17:10I'm not really sure
- 17:10how to go about this process
- 17:11can we walk them through like
- 17:13say I'm
- 17:14I mean I
- 17:14let's let's use me as an example
- 17:16like say
- 17:16I've got I've got a sample that I think that we could
- 17:19we're gonna biopsy and um
- 17:22I wanna make sure that some of that tissue
- 17:24ends up in the Biobank not just say
- 17:26in like
- 17:27the hospital stores um
- 17:29what's the process like for me
- 17:31yeah so if a patient's interested
- 17:33you know they can go to the Insight Biobank website
- 17:35and they can put in their information and request it
- 17:37then what happens is there's a consent where virtually
- 17:41someone from the biobank will walk you through
- 17:43and have you sign an electronic consent about um
- 17:46you know storing the tissue
- 17:47and that's a great time if you have any questions like
- 17:50you know what is
- 17:51can the tissue be used for
- 17:52can it come back to me can they know it's me
- 17:54all of those questions and any other concerns you have
- 17:57that's the perfect time to answer that
- 17:59and that consent visit
- 18:01go to that consent with your questions
- 18:02you can always say actually
- 18:03I don't want to participate
- 18:05but the only way to get those questions answered
- 18:07is to go to the consent visit
- 18:08ask the questions and get it done
- 18:11once you sign the consent form
- 18:13then um
- 18:14you can let you can either talk to your surgeon
- 18:16or the interventional radiologist yourselves
- 18:18otherwise
- 18:18the Biobank team can try reaching out to their clinic
- 18:21and then they'll either send all the necessary
- 18:24you know sample collection tools
- 18:26vials to the clinic or to you
- 18:29and then all you need to do is make sure
- 18:31when you go in for your surgery or biopsy
- 18:33that the team performing the biopsy has that tissue
- 18:36they put the tissue in there
- 18:37it comes in with a FedEx label
- 18:39it's shipped back um
- 18:41usually the institution ships it
- 18:42maybe they ask you to ship it
- 18:44but you drop it off it's a prepaid shipping label
- 18:46it goes back to the lab and it's all done
- 18:48and so um
- 18:49it is very easy a lot of times in the consent what
- 18:52which we ask what
- 18:54or the thing that we ask our interventionalist to do
- 18:56is to collect as much tissue as they feel is safe
- 19:00without increasing the risk
- 19:01so a lot of times when you do a biopsy
- 19:03we do two or three cores
- 19:05sometimes four
- 19:06sometimes we need to biopsy the lesions large enough
- 19:09and it's in an area
- 19:10where you could safely do eight cores
- 19:11they just don't always need that
- 19:13but what we tell people is collect up collect
- 19:16we ideally would like this much or up to
- 19:20whatever you feel
- 19:21doesn't increase the risk of the biopsy
- 19:22for the patient
- 19:23cause we never want to increase the risk
- 19:25and we let them determine that
- 19:26and then we take whatever they feel is safe
- 19:31so I know this is gonna come up
- 19:32we have tons of people who
- 19:34you know live in the world of like
- 19:36cancer and we are trying to understand like okay
- 19:39does having a biopsy
- 19:40somehow increase my risk for spread
- 19:42and I feel like you and I've had this conversation
- 19:44specifically um
- 19:46a number of times
- 19:47but can you just kind of clarify again
- 19:49like that myth around like
- 19:51kind of the what is it
- 19:52it's like the that if you have a needle point biopsy
- 19:55that the path of the needle pulling out is gonna like
- 19:57somehow be a path of spread
- 19:59can you
- 19:59can you help clarify what we know about uveal's behavior
- 20:21yeah so there is a couple of cancers
- 20:23it's very rare
- 20:23where we know that if you biopsy something
- 20:25it can grow along the needle track
- 20:27that is not uveal melanoma and actually
- 20:29all of the data we have from uveal melanoma suggests that
- 20:34for patients who have get
- 20:36will develop metastatic disease
- 20:38that disease has probably already spread
- 20:40and is remaining dormant in the body
- 20:42even before we find the tumor in the eye
- 20:45and that's why treating the tumor in the eye
- 20:47may or may not affect outcomes of metastasis
- 20:50and so you know
- 20:52if the cancer spreads it's probably already done
- 20:54so it's probably just doing so in a single cell level
- 20:57hanging out and hiding to see something on a pet scan
- 21:00typically you need a billion cells in one spot
- 21:02so it takes a while for the cancer to grow that much
- 21:05so
- 21:06doing a biopsy
- 21:07absolutely does not increase the risk of cancer spread
- 21:11or growth or anything like that
- 21:12in patients with uveal melanoma
- 21:15okay so then when you say like
- 21:17get the amount of biopsy tissue that's safe to do
- 21:20like that's more
- 21:21is that more like
- 21:21from a physical comfort level of the patient
- 21:23of just making sure it's not too invasive of a biopsy
- 21:26um
- 21:27I guess I'm just trying to make sure that I understand
- 21:29and help clarify for those of our people listening
- 21:32yeah exactly
- 21:33so it's a thing for the patient or the
- 21:35also the proceduralist so sometimes
- 21:36you know there's a lesion that's in a tight spot
- 21:39they may only be able to get one core
- 21:40then we don't collect for the biobank
- 21:41if they feel like it's gonna be risky for just one
- 21:44then we don't take more um
- 21:46but sometimes it's you know
- 21:47some people just have a spot on the skin
- 21:49and you could either just take a part of the thing
- 21:51or take it all off and it's really no different
- 21:54and that's an example where we may get more tissue
- 21:56because it is safe just to take
- 21:58you know a larger lesion of the skin
- 22:00versus just a smaller component of that
- 22:03okay so
- 22:04I wanna shift a little bit
- 22:05away from the metastatic side of things
- 22:07cause obviously we've got metastatic disease
- 22:09biopsies that can happen for various different reasons
- 22:12um whether it's to confirm metastatic diagnosis
- 22:14or to join a clinical trial
- 22:16I know is another setting where you might need um
- 22:19a fresh biopsy like
- 22:20within a certain amount of time
- 22:21um so like
- 22:22you know various different opportunities
- 22:24throughout the metastatic journey
- 22:25to obtain biopsies and to kind of
- 22:27volunteer that tissue to go into the Insight Biobank
- 22:30but if we go back to the beginning of initial diagnosis
- 22:33how do you how do you like
- 22:35see this working from like
- 22:38an ocular oncology and like the
- 22:39the original primary diagnosis point
- 22:42cause we've got needle point biopsies for like
- 22:44some tumors and then we have like
- 22:46enucleation obviously
- 22:47for others um
- 22:49proton beam therapy
- 22:50which is a totally different treatment for
- 22:51you know other parts of the eye
- 22:53um so yeah
- 22:54how how can we kind of see this working
- 22:56with the primary tumor
- 22:58yeah there's a couple things we could do
- 23:00with the primary tumor
- 23:00but the primary tumor is a little more challenging
- 23:02so right now we're starting with metastatic
- 23:04and we'll roll in the primary tumors in the future
- 23:07with the biobank with the primary tumor
- 23:09a lot of times if you're getting
- 23:10you know proton or plaque brachytherapy
- 23:13we just do a fine needle biopsy
- 23:15which really only gets you a couple of cells
- 23:17to do kind of deep sequencing of DNA
- 23:20RNA or protein
- 23:22usually the more you put in
- 23:23the more accurate it is so
- 23:24it's hard to ask broad questions on targeted biopsy
- 23:28such as that which is why the Castle test is
- 23:30you know an RNA test that only looks at
- 23:32I think up to 15 genes
- 23:34if that because with DNA and RNA
- 23:38you know you can ask if you
- 23:40if you are only looking at a couple of things
- 23:42you don't need much tissue
- 23:43the more things you look at
- 23:44the more you do so with a biopsy
- 23:46you can ask very specific questions
- 23:48but not broad questions
- 23:50now um
- 23:52the we are
- 23:53there is emerging data that vitreal fluid biopsy
- 23:55the fluid within the eye which is safe to take
- 23:58may contain some of the same DNA
- 24:01protein and cells as a uveal melanoma biopsy
- 24:03and that's a situation where we may be able to get more
- 24:05and there's you know
- 24:06I think UCSF
- 24:07and Stanford are doing a lot of research in this space
- 24:10and so in the future the Biobank may expand into that
- 24:13since we may be able to get fluid where we could um
- 24:16be more useful on a kind of bigger question answer
- 24:20and then for enucleation
- 24:22um you would think if you remove the tumor
- 24:24it would be very easy to send it to the biobank
- 24:26the problem is these are still pretty small right
- 24:28even a large tumor is 2 centimeters
- 24:31and when we do a surgery
- 24:34like enucleation where margins are very important
- 24:36we need to make sure we got all the margins
- 24:38that's not in the nerve
- 24:40it's hard to take a portion out of the enucleation
- 24:43to send it to pathology especially
- 24:46if we think that could affect their determination of
- 24:49did they get it all or not
- 24:51because again
- 24:51the number one thing is
- 24:53we don't interfere with patient care
- 24:55and so we can't ask that
- 24:56we can't prevent pathology from asking that question
- 24:59so that is a little more nuance
- 25:00but some patients you can get that
- 25:03no that's
- 25:04I mean I'm glad that we talked about that
- 25:05because
- 25:06I definitely believe that this will be a question
- 25:08especially you know
- 25:09as we're able to move to any level of the biobank
- 25:11taking tissue from a primary tumor
- 25:13like that's definitely gonna come up because like
- 25:16in my head I'm thinking like
- 25:17I've seen the picture of my eye
- 25:19from when my doctor enucleated it
- 25:21she showed it to me looks like a little pomegranate
- 25:23my head says well
- 25:24I can't I just donate that eye to science
- 25:26but I also know that it was sliced through
- 25:29like for multiple different slides
- 25:31because they had to verify that it didn't
- 25:33you know extend beyond the actual eyeball globe and
- 25:37you know kind of that
- 25:38that was a huge influencing
- 25:40I guess bit of the biopsy for my actual treatment plan
- 25:44so like you said
- 25:45like so important
- 25:45that it doesn't interfere
- 25:47with the treatment of the patient
- 25:49um I have like
- 25:50one more question
- 25:51and I guess this is kind of more around
- 25:53like the clinical trial space
- 25:54um
- 25:56if someone's getting a biopsy for a clinical trial
- 25:58can they also like
- 26:00as long as it's safe to do so
- 26:01ask for additional samples to be sent into the biobank
- 26:05like for a biopsy of a metastatic tumor
- 26:09yeah you absolutely can still ask
- 26:11it comes down to what is safe to collect
- 26:12so if there you know
- 26:14sometimes when we do a biopsy for research
- 26:16we need a biopsy for pathology
- 26:18as well cause we're sending
- 26:19you know circulating tumor DNA
- 26:20and we need tissue for that
- 26:22then we need to collect tissue for the study
- 26:23and then the biobank would come third
- 26:25cause we would never interfere with the patient care
- 26:27and the first two or more patient care
- 26:29and so it might be that um
- 26:31for smaller lesions they can't get enough safely
- 26:34it could be that it's a large lesion
- 26:35they absolutely can
- 26:36but it's absolutely a question that can be asked yep
- 26:40okay awesome
- 26:41well I feel like this has been super enlightening um
- 26:44what do you hope that ocular melanoma patients today
- 26:46understand about the future
- 26:47because of a resource like the Insight Biobank
- 26:51yeah the goal of a biobank like this
- 26:54is to really help investigators
- 26:56find better ways to treat the cancer in the future
- 26:59you know and so we're really hoping that
- 27:02you know we can use this
- 27:03to develop new therapies for future patients
- 27:06I think the thing that you know
- 27:09I think one of the unique things
- 27:10about the uveal melanoma patient population
- 27:12which is one of the reasons
- 27:13I love working with this group
- 27:15and A Cure In Sight
- 27:16is just how much drive and support there are
- 27:20from the patients to partner and cure this disease
- 27:22and I think that's super unique
- 27:24and I also think it's incredibly important
- 27:26when it comes to rare cancer
- 27:28no one person's gonna cure this disease
- 27:30no matter how great that one person is
- 27:32it's going to take a team
- 27:33and I don't I'm not aware of any other disease
- 27:37where the patients
- 27:38and the advocacy groups are such strong partners
- 27:40or members of the team as uveal melanoma
- 27:42so I think a lot of it is
- 27:44just keep doing what you guys are doing
- 27:46cause you guys are already leading the field
- 27:49well thank you so much
- 27:50Doctor Moser um
- 27:51we can't thank you enough for just all of the
- 27:53the continued research that you're doing
- 27:55and for the treatment of the patients that you have
- 27:57on the west side of the United States
- 28:00and
- 28:01we're just really grateful that you're willing to be
- 28:04just be a part of the team with all of us
- 28:06and I love what you said about that
- 28:08and just to kind of close out
- 28:10I want to also make sure that we thank our sponsors
- 28:12thanks to our listeners and if you haven't yet
- 28:14make sure that you subscribe
- 28:15hit that little button on YouTube
- 28:17or on your podcast platform
- 28:19and share this with some friends
- 28:20um like Doctor Moser said
- 28:22the best way
- 28:22that we can get the Biobank to move forward
- 28:24is to have more samples
- 28:25so the more people who know about it
- 28:26the better um
- 28:28we'll also put the link to the Biobank
- 28:30in the show notes so that you guys have access to that
- 28:33and you can share that with friends
- 28:35um and
- 28:35you know just
- 28:36let's just spread the word
- 28:37because
- 28:37that's how we're gonna help the needle move forward
- 28:39on research so thanks again
- 28:41Doctor Moser
- 28:42thanks for having me
