Latest / The Eye Believe Podcast / ESMO 2025 Highlights: Key Uveal Melanoma Trial Updates with Dr. Hadfield | The Eye Believe Podcast
Transcript
- 0:03hey everybody
- 0:03welcome back to the Eye Believe Podcast
- 0:05today I'm joined with Doctor Matt Hadfield
- 0:08and he is at Providence Rhode Island
- 0:10and he's a medical oncologist
- 0:11if you haven't heard of him
- 0:12please check out the physician finder on
- 0:14ACureInSight.org
- 0:15you can find other doctors in your local areas
- 0:18and just kind of follow your zip code
- 0:20but we are gonna be chatting about major
- 0:22new uveal melanoma research updates
- 0:24and this is super helpful and important to patients
- 0:27because honestly
- 0:28like the ESMO studies that came out at the end of 2025
- 0:31I think were probably some of the most hopeful studies
- 0:33that I have seen as a patient in like
- 0:36the five and a half years
- 0:36that I have been doing this podcast
- 0:38you know in addition to just the five and a half years
- 0:40I've been a uveal melanoma patient myself
- 0:42so tune in stay tuned for like
- 0:45the rest of the studies we're gonna reference
- 0:46but also please check that out on our website
- 0:49we'll link that in the show notes
- 0:50we kind of were talking before we started recording
- 0:52and Doctor Hadfield and I decided we were gonna chat
- 0:55briefly about something
- 0:56that's actually not in our list of ESMO studies
- 0:59there was an ASCO study on dietary fiber
- 1:01and immunotherapy that came out in
- 1:02I think the summer of 2025
- 1:04and Dr. Hadfield and I were just talking
- 1:06about how important this is
- 1:07and why more patients should know about it
- 1:09so um
- 1:10Dr. Hadfield
- 1:10you wanna tell us a little more about that one
- 1:12yeah no
- 1:13thank you for having me and it was uh
- 1:15interesting
- 1:15as we were having kind of that sidebar conversation
- 1:17about your experience in clinic and
- 1:19and what
- 1:19uh you and your urologist
- 1:21uh have been speaking about
- 1:22and
- 1:22how high fiber diets
- 1:23have really entered the conversation
- 1:25and it's such an important thing to talk about
- 1:27so at ASCO 2025 the annual meeting
- 1:30there was the diet trial which was a randomized trial
- 1:32showing that a high fiber diet
- 1:33which was defined in the study as
- 1:3530 to 50 grams of fiber a day
- 1:37significantly improved response rates
- 1:39and survival for melanoma patients on immunotherapy
- 1:41so this this
- 1:41this study showed that those that had a high fiber diet
- 1:45had an objective rate of response of 77% versus 29% um
- 1:49and those not having a high fiber diet
- 1:51and then the median event free survival uh
- 1:53was not reached in the high uh
- 1:55fiber arm um
- 1:56versus 7.6 in the control arm
- 1:58so I mean
- 1:58this is this is uh
- 2:00honestly one of the most um
- 2:02you know when we think about practice changing studies
- 2:05we we often think about those
- 2:06that have remarkable increases in efficacy um
- 2:10or or new therapeutic combinations that are
- 2:13are you know
- 2:14showing significant benefit
- 2:16but this is one of the most important
- 2:18practice changing studies
- 2:19that's come out in the last year
- 2:20given the the risk of having a high fiber diet is
- 2:24you know very
- 2:24very low um
- 2:26and uh the
- 2:27the benefit here is tremendous
- 2:29and I think it's important to highlight too um
- 2:32this study really stipulates and
- 2:34and and show that it's
- 2:36it's really the process of
- 2:37or the the eating a high fiber diet
- 2:41high fiber foods not necessarily fiber supplements
- 2:43because of
- 2:43the digestion of that high fiber food content
- 2:45is really what's uh
- 2:46recruiting these pro immunotherapeutic uh
- 2:49microbiome uh
- 2:50organisms to to propagate that response
- 2:53so um
- 2:54if you're a patient who is on immunotherapy um
- 2:56obviously this was in melanoma patients
- 2:58but um I
- 2:59I think it's it's a it's
- 3:01it's a logical assumption that it
- 3:04this is beneficial to anyone on immunotherapy
- 3:05whether or not you have uveal melanoma
- 3:06cutaneous melanoma or another malignancy
- 3:08so definitely
- 3:09something that you should
- 3:09speak to your oncologist about
- 3:10cause it's very important
- 3:12yeah for sure
- 3:13um and just from a
- 3:14you know personal note
- 3:15I've been doing a high fiber diet
- 3:16after Doctor Moser recommended that for me
- 3:18in addition to my opdualag immunotherapy infusions
- 3:21and I thought it was gonna be kind of hard
- 3:23and then I actually was able to find a few
- 3:25like good high fiber foods that are like
- 3:27good quality high quality
- 3:29and they're not you know
- 3:30they're not like a Metamucil supplement
- 3:31like you mentioned like
- 3:32so I am you know
- 3:33like
- 3:34I'm digesting the food versus um
- 3:36taking a supplement
- 3:37but another kind of like
- 3:39little resource that might be out there for you
- 3:41depending on your insurance
- 3:42um I know there's various different like
- 3:43nutritionist apps that you can join and that like um
- 3:47that can be covered by insurance
- 3:48I know for me like
- 3:49I've been using the nourish app
- 3:51and so I have a dietitian who actually
- 3:53I can help like
- 3:54kind of figure out okay
- 3:55what foods are out there like
- 3:56what could I use um
- 3:58that are Whole Foods to like
- 4:00bring that supplemental fiber into my
- 4:01into my day
- 4:02I just thought it was so fascinating and
- 4:04and as somebody who really like
- 4:05values the holistic stuff
- 4:07like this was
- 4:08this was a really neat study for me
- 4:09and I was like say less or
- 4:11you know
- 4:12I will do it like that that's not a
- 4:14that's not a hard thing for me to try
- 4:15no it has
- 4:16most definitely
- 4:17entered the conversation of every patient that I have
- 4:19that is on immunotherapy or um
- 4:22is starting immunotherapy
- 4:23so it's it's
- 4:24it's so good to I'm so glad you brought that up
- 4:25because it's an important thing to touch on
- 4:27yeah for sure
- 4:28okay well
- 4:28we'll make sure to link that ASCO study as well
- 4:31in our show notes and in the description
- 4:32for those of you listening on our YouTube channel
- 4:35which by the way
- 4:35thanks for being here thanks for subscribing
- 4:38but as we get into the rest of our conversation
- 4:40can we just
- 4:40cover a couple of things around kind of the phrases
- 4:43the terminology in these studies
- 4:45so that we know what patients are
- 4:48so that patients listening at home like
- 4:49kind of know what these mean
- 4:50so I'm gonna give you like
- 4:52just one at a time rapid fire
- 4:53and we can just go through each of these
- 4:55so can you define phase 1 versus phase 2 and phase 3
- 4:59in a trial yeah
- 5:00no absolutely
- 5:01and and um
- 5:02these are these are terms that can get very
- 5:04very overwhelming very very quickly
- 5:06so it's a great thing to go through them
- 5:07phase one studies are
- 5:09by definition safety studies
- 5:10and it's the first time a
- 5:11drug is being used in patients
- 5:13so these are
- 5:14these are drugs that have had years and years
- 5:16and years of preclinical development
- 5:18they've been studied extensively
- 5:19and now we're at the point where
- 5:20there are very promising therapies
- 5:22that have made it to the clinic
- 5:23but they're very small studies
- 5:25they include just one arm of patients
- 5:27and depending on the study
- 5:28they may be in one specific type of tumor type
- 5:31they may be in multiple tumor types
- 5:34multiple solid tumor malignancies
- 5:36or they may be in an enriched tumor type
- 5:38meaning that there is a
- 5:39a biomarker that is being tested
- 5:42and then we are studying
- 5:43if the patient has that biomarker on their tumor
- 5:46if the drug works well in that patient population
- 5:48um and then just quickly
- 5:50phase 2 studies are
- 5:51are typically slightly larger studies
- 5:53where you're looking at something like a response rate
- 5:55which we can talk about in a second
- 5:57and it's limited to just one tumor type most often
- 6:01and then phase 3 studies are really when you uh
- 6:04you get into randomizing uh
- 6:06to the new therapy versus an existing therapy
- 6:08to determine which one is better
- 6:09and you know
- 6:10in terms of the developmental process
- 6:12phase 3 uh
- 6:14trials are the largest most robust uh
- 6:16in terms of the statistics that go into them and
- 6:18and that's the
- 6:19the trials that typically lead to them being approved
- 6:21by the uh
- 6:22the regulatory bodies like the FDA
- 6:24okay um
- 6:25you mentioned like
- 6:27smaller studies um
- 6:29I know like
- 6:29some of the other terms that come up
- 6:30are randomized versus single arm
- 6:32so what's the difference between those two
- 6:34right so um
- 6:36when you have a a patient that is getting enrolled on a
- 6:39a single arm study
- 6:40that means when you sign the consent form
- 6:42you talk to the the treating physician
- 6:44you are being enrolled in one arm
- 6:45meaning that there is just one therapeutic uh
- 6:48intervention that you're getting
- 6:49so
- 6:50for instance uh
- 6:51we're going to talk about the Immatics trial
- 6:53that Doctor Sapna Patel presented at ESMO
- 6:56and that was a single arm study
- 6:58so those that got enrolled in the study
- 7:00received that study drug there was no other
- 7:01other intervention
- 7:03a randomized study is when you enroll in the study
- 7:06and then there is a a blinded randomization process
- 7:09where you get enrolled to an experimental arm
- 7:12which may include standard of care plus something else
- 7:15this new experimental drug
- 7:17or you get enrolled to standard of care
- 7:19and that can be sometimes blinded or unblinded
- 7:21so blinded would mean that you're enrolled to a group
- 7:24and you don't know if you're getting the new study
- 7:25drug or not and then unblinded as you do
- 7:28but that's kind of the breakdown
- 7:30phase 3 studies are randomized
- 7:31phase 2 studies are sometimes randomized
- 7:33sometimes not depending on the nature of the study
- 7:37okay that makes sense
- 7:38uh alright
- 7:39we mentioned like overall survival
- 7:41response rate things like that
- 7:42what does response rate mean
- 7:43and what about progression free survival
- 7:45versus overall survival right
- 7:48so um
- 7:49response rate is when we look at the
- 7:53the response of the tumor to the drug
- 7:55so if if the
- 7:56if the tumor is staying the same or getting smaller
- 7:59after we start a therapy
- 8:00we would consider that a response
- 8:02and then that's how we calculate the response rate
- 8:05response rates can be then further classified into
- 8:07stable disease
- 8:08meaning that the tumors have stayed the same
- 8:10a partial response
- 8:11meaning that the tumors have gotten smaller
- 8:13and then a complete response
- 8:14meaning that the tumors have gone away completely
- 8:16and then an aggregate of all those terms together
- 8:19is something
- 8:19that you may see as a clinical benefit rate
- 8:21which means a CBR in a study just means that it
- 8:24it encompasses one of those things as a
- 8:26as a whole group and then progressive disease uh
- 8:30would mean unfortunately
- 8:31that the cancer has gotten larger
- 8:32or is in new areas that it wasn't previously in
- 8:35okay and then progression free survival
- 8:38or PFS versus OS like
- 8:40I think that maybe is a little self explanatory
- 8:43but let's cover it just in case
- 8:44yeah so
- 8:45progression free survival is essentially
- 8:47how long you've been on the trial
- 8:49before you have evidence that the
- 8:51the drugs not working anymore
- 8:52whereas
- 8:53overall survival is how long the patient stayed alive
- 8:56no matter what happened after they came off the study
- 8:58so for instance
- 8:59overall survival you know
- 9:01if you're on a trial for instance
- 9:02then you come off and you go on another trial
- 9:04we would still calculate the overall survival
- 9:06in the future
- 9:07and and account kind of for those
- 9:08those therapeutic modalities as well
- 9:11yeah especially if like
- 9:12the trial had like
- 9:13a specific end point where it was like OK
- 9:15this is you know
- 9:16you have 12 months on a study max
- 9:18and like that's it
- 9:19we take you off the drug at 12 months
- 9:20and then we follow I I know that was the case for like
- 9:22an adjuvant trial that I was in
- 9:23like years ago
- 9:24it was kind of like a okay
- 9:26like
- 9:26we're still gonna follow you no matter what happens
- 9:29as you know
- 9:29throughout the rest of your life
- 9:31so that makes sense right
- 9:32and why I guess
- 9:33why do you feel like as an oncologist
- 9:35why do you feel like
- 9:36it's important that you don't just look at
- 9:38for example the response rate
- 9:39because I know sometimes
- 9:40it can feel a little misleading to patients
- 9:42when they look at these studies
- 9:43to be like oh
- 9:44the response rate is only
- 9:45you know 40% or 30%
- 9:47like that doesn't look that great
- 9:48but then if you as a clinician are looking at
- 9:50you know
- 9:50overall survival or progression free survival durations
- 9:53like how do those kind of way into your decision
- 9:55and in saying oh
- 9:56this would actually be a pretty promising option
- 9:59a great question that comes up quite a bit and and
- 10:01and one of the things that I
- 10:02I would say is a challenge
- 10:03because when studies are are
- 10:06you know put out into the wide stream media or
- 10:09or biotech news
- 10:11they they will cling to these 1 1 metrics sometimes to
- 10:14to highlight uh
- 10:15a benefit of a study but
- 10:17you know
- 10:18response rate is really only taking into consideration
- 10:21one aspect
- 10:22of the overall picture of how a drug is working
- 10:25so uh
- 10:26for instance
- 10:27if you
- 10:27if you look at something like small cell lung cancer
- 10:29chemotherapy has a a very high response rate
- 10:32meaning that when you start chemotherapy the
- 10:35the tumors get much much smaller uh
- 10:37but there's a very quick relapse time
- 10:40so while the response rate is very good
- 10:42the progression free survival is not
- 10:44and that's important to keep in mind
- 10:46because in certain clinical situations
- 10:48you may need a really quick response rate
- 10:50if there's a chance that the
- 10:51the disease burden
- 10:52is going to cause clinical issues for the patient
- 10:55but when you think about progression free survival
- 10:58and more importantly overall survival
- 11:00are we actually making a difference
- 11:01in the amount of time we're giving a patient uh
- 11:04with these drugs so when
- 11:06when you think about these things
- 11:07you have to keep all of this in mind
- 11:08and the most important thing
- 11:10that I think we don't talk about enough
- 11:11is the side effects of the drugs
- 11:13so if you have something that has a
- 11:14a response rate that's high
- 11:16but a high chance of relapse
- 11:18or set a different way a
- 11:19a shorter progression free survival
- 11:21meaning a shorter time until you
- 11:22you relapse there's a high risk of toxicity
- 11:25all of these things
- 11:26need to be talked about with the patient
- 11:27because ultimately it's a decision between the
- 11:28the physician and the patient to see um
- 11:31that they understand those
- 11:32those data points and
- 11:32and what the risks and benefits are
- 11:34yeah like the cost versus the benefit
- 11:36all of that yeah
- 11:38okay um alright
- 11:39so rare cancer trials obviously
- 11:42we know uveal melanoma is rare
- 11:44um most of these studies
- 11:45have pretty small numbers of people
- 11:47enrolled in the trials you know
- 11:48as they're referencing their data
- 11:50right now
- 11:51why are rare cancer trials smaller
- 11:54so rare cancer trials are historically uh
- 11:57difficult because by virtue
- 11:59there are not as many patients with these cancers
- 12:01so if you take a cancer that's a little bit more common
- 12:06like non small cell lung cancer
- 12:08the numbers on the trials will be much larger
- 12:10because the patient populations are
- 12:11are much larger that are going to need a trial
- 12:14and have access to a trial
- 12:15uveal melanoma is very unique
- 12:17and that it's it's a rare cancer
- 12:18so when we think about trying to enroll the
- 12:21the patients onto the study
- 12:23it requires multiple sites
- 12:24across multiple geographic regions
- 12:26and takes a long time
- 12:27because there's just less patients to enroll
- 12:29we accept lower numbers on those studies
- 12:31and look at the data a little differently
- 12:33because we know that it's hard to enroll those studies
- 12:35the other thing that is now happening more and more
- 12:38is trying to characterize tumors in different ways
- 12:40so not as much in uveal melanoma
- 12:43but other
- 12:44other tumors that have common genetic mutations
- 12:48or things of that nature
- 12:50we enroll in something called basket studies
- 12:52where you enroll lots of different tumor types
- 12:54that have maybe a
- 12:55one similar characteristic
- 12:57and then
- 12:57see if you can benefit the whole patient population
- 13:00by using that common commonality to
- 13:03to treat them yeah no
- 13:05I think that's super cool um
- 13:07and I can see how like
- 13:08it could it could kind of be beneficial in each area
- 13:11like
- 13:12I mean I
- 13:12I know for example
- 13:14like
- 13:14Kimmtrak Hepzato
- 13:15like those got to approval
- 13:16and they're unique to uveal melanoma
- 13:19which is great um
- 13:20but it's also really good when we have um
- 13:23drugs that get approved and they happen to be approved
- 13:25for multiple different cancer types
- 13:26and also happen to work for uveal melanoma
- 13:28in some capacity um
- 13:30which I think that you know
- 13:31we're still kind of evolving in
- 13:32in the trials
- 13:32and seeing stuff that is actually effective
- 13:35in those ways um
- 13:37but I can see how that would also like
- 13:39yield kind of like
- 13:40look like a bigger study but
- 13:41when you kind of
- 13:42look at each little basket that you're putting it into
- 13:45the uveal melanoma basket
- 13:48is going to tend to be smaller
- 13:49just because our patient population is
- 13:51by nature smaller
- 13:53right which feels really weird
- 13:54because I feel like
- 13:55there's thousands of us that are metastatic
- 13:57like how small is that
- 13:58well
- 13:59and thankfully
- 14:00to credits like A Cure In Sight
- 14:02patient advocacy groups are so important
- 14:04I mean patient advocacy groups are important
- 14:06across all cancers or all diseases really
- 14:08but especially in these uh
- 14:10situations where
- 14:11you know if you weren't aware of this network
- 14:14you would you know
- 14:15have a hard time necessarily connecting with people
- 14:17because it is less common than other cancers
- 14:19yeah for sure
- 14:21okay so let's switch gears
- 14:22let's actually chat about these studies
- 14:24that came out during ESMO um
- 14:26we're gonna run through these
- 14:27uh we're gonna give kind of
- 14:28the most time to the ones that had
- 14:30maybe the most impact
- 14:31but I do wanna just give a heads up
- 14:33that if you have more questions
- 14:35like please
- 14:35don't hesitate to reach out to us at A Cure In Sight
- 14:38Contact@ACureInSight.org
- 14:39drop your comments and questions below
- 14:41we'll do our best to get those answers to you um
- 14:43by reaching out to Doctor Hadfield or other physicians
- 14:45and just keep in mind too
- 14:47that some of the things that we cover here um
- 14:50stay tuned for the rest of the year
- 14:52especially this first quarter
- 14:53in February
- 14:54we're going to be running a quarterly webinar
- 14:56our our Eye On The Expert webinar series
- 14:59and our first webinar
- 15:00is actually going to cover more in depth
- 15:02on this first study so
- 15:03Doctor Hadfield
- 15:04let's talk a little more about the Chopin trial
- 15:06and I'm like
- 15:07gonna kick myself I'm trying to only say Chopin
- 15:09not Chopin because I know it's Chopin um
- 15:13but yeah
- 15:14let's talk about that one
- 15:15um this one was Hepzato plus Ipi Nivo
- 15:18and this was done in Europe
- 15:19I believe this was done in the Netherlands
- 15:21so the the uh
- 15:23Chopin trial um
- 15:24combined uh
- 15:25percutaneous hepatic uh
- 15:26perfusion or Hepzato
- 15:28with ipilimumab plus nivolumab
- 15:30in metastatic uveal melanoma
- 15:32so this was a single center uh
- 15:34meaning it occurred at one place
- 15:35open label meaning that everyone knew what the drug was
- 15:38uh randomized study where uh
- 15:40the randomization um
- 15:42was essentially between patients
- 15:45to receive two courses of Hepzato
- 15:47which is this perfusion uh
- 15:49in weeks 1 and 7
- 15:50with or without alternating treatments
- 15:51of ipilimumab and nivolumab
- 15:53which if you're not familiar
- 15:54are immune checkpoint inhibitors
- 15:56which have been used in uveal melanoma
- 15:57but uh uh
- 15:58also more so in cutaneous melanoma in the past
- 16:02and what this essentially showed
- 16:03that progression free survival at one year
- 16:06in the combination group was 54.7%
- 16:09versus 15.8% in the control group
- 16:12so this is very important data to
- 16:14to go over basically what we
- 16:16what we showed here
- 16:17was pretty significant and interesting
- 16:20difference between progression free survival
- 16:22and those receiving immunotherapy
- 16:23plus the hepatic perfusion
- 16:25as opposed to just the hepatic perfusion alone
- 16:28uh overall survival at one year was
- 16:29was almost the same 82.8% in the uh
- 16:32combination group versus
- 16:3482.2%
- 16:36in the control arm and control arm here uh
- 16:39just a
- 16:40if you hear that reference
- 16:41is the
- 16:41without the Ipi Nivo
- 16:45okay so control arm
- 16:46meaning they only had the two rounds of the Hepzato
- 16:49Yep that's right
- 16:50the the PHP
- 16:51the percutaneous hepatic perfusion
- 16:53oh my goodness
- 16:54I can say it um
- 16:56okay and then what about our response rate
- 16:58do we have a response rate for this study
- 17:00so the
- 17:00the best overall response rate in the combination group
- 17:03was was pretty impressively
- 17:0476.3 versus 39.5 in the in the control arm
- 17:09so just for reference like
- 17:11is Hepzato I mean
- 17:12Hepzato got approved and
- 17:14and it's also been approved as chemosat in Europe
- 17:17um it got approved on this original
- 17:19you know on this original response rate like
- 17:21you know and
- 17:22and actually we should
- 17:23we should kind of give the caveat
- 17:24that the Hepzato treatment
- 17:26the chemosat treatment
- 17:27they were approved contingent on the trial data
- 17:30of six consecutive treatments
- 17:32this is only showing two Hepzato treatments
- 17:34so like
- 17:35I feel like we have to take some of that like
- 17:36grain of you know
- 17:37some of that response rate with a grain of salt
- 17:39knowing that they only did like
- 17:40a small chunk of the
- 17:42how could we alternate these treatments
- 17:44yeah and I
- 17:45I think um
- 17:47there yes
- 17:48that that is a very
- 17:49very good point and
- 17:50and it raises another point that
- 17:51when you're reviewing studies in general
- 17:53it's very hard and and
- 17:55and in many ways
- 17:56not fair to compare different trials to each other
- 17:59because each trial had was designed statistically to
- 18:04to answer one question and it does not
- 18:07you know cross over to other trials
- 18:09each one has their own answer
- 18:10the same questions for sure
- 18:11exactly and it statistically
- 18:12they don't answer the same question
- 18:13the patient populations may be different
- 18:15the enrollment may different
- 18:16exclusion and inclusion criteria
- 18:17so lots of things to consider
- 18:19but at least based on this study
- 18:20we see a a
- 18:21a remarkably uh
- 18:23in improved progression free survival
- 18:24and overall response rate with the combination
- 18:27yeah and okay
- 18:28so like
- 18:29there's a lot of qualms in uveal melanoma
- 18:32about people who are like very
- 18:35just hardcore anti Ipi Nivo
- 18:37they're very like
- 18:38very afraid of it because of the side effects
- 18:39they hear a lot of the
- 18:40the really big hard side effect stories
- 18:42which I know do exist right
- 18:44Ipi Nivo does tend to be a little bit of a harsher
- 18:46option in immunotherapies
- 18:48even for cutaneous patients
- 18:50but maybe we kind of caveat that with the okay
- 18:53but now we know about fiber
- 18:55so maybe that helps that's
- 18:57that's an option um
- 18:59but also like
- 19:00what about the study was unique about what they
- 19:02like how they dosed Ipi Nivo
- 19:03did they do a normal dose
- 19:05did they do kind of a lower dose

- 19:22to learn more visit Castlebiosciences.com
- 19:25it's challenging when you think about
- 19:28uh uveal melanoma because um
- 19:30when when we talk about uh
- 19:31Ipi Nivo dosing
- 19:33a very important caveat is that nivolumab
- 19:35does not have a dose dependent toxicity uh
- 19:38nor do any of the other PD-1 inhibitors
- 19:40so uh
- 19:41and and that would include things like pembrolizumab
- 19:43durvalumab
- 19:44but the ipilimumab does so
- 19:47you know and
- 19:48and you patients may hear
- 19:49you know full dose Ipi Nivo
- 19:51which is uh
- 19:523 milligrams per uh
- 19:53kilogram and then 1 mg of the PD-1 inhibitor
- 19:56and then flip dose IPI would be the opposite of that
- 19:59so
- 20:00you know it it
- 20:01this study long story short
- 20:04did not show any emerging new safety
- 20:07side effects or toxicities with the combination
- 20:10or with the the two modalities on their own
- 20:13um but I do think it
- 20:14it raises a really important point that um
- 20:16immunotherapy toxicities is something that we can't uh
- 20:19we can't overlook and in many ways
- 20:22is a challenge for the patient and the
- 20:24the um
- 20:26oncoligist
- 20:26because we don't have a great way of predicting them
- 20:28so we don't know um
- 20:31we know when you give Ipi Nivo
- 20:33there's a 50% chance that you have a grade 3 toxicity
- 20:35meaning that we have to stop the drug
- 20:38stop the drugs start steroids
- 20:40high dose steroids and and
- 20:41and try and uh
- 20:42reduce whatever inflammatory response is
- 20:44is going on
- 20:45and there's like
- 20:45a 90% chance of having any toxicity at all
- 20:48so you know the
- 20:50these are these are understandably scary numbers
- 20:53but at least this study was in line
- 20:55that this is a safe regimen to to give
- 20:59yeah absolutely
- 21:00um okay
- 21:01so like for patients who hear these numbers
- 21:03about the Chopin trial um
- 21:05obviously this trial has not occurred in the States
- 21:07and my understanding is that it's not like
- 21:09going to enroll in the States
- 21:10this is more informative like
- 21:12for oncologists to hear and know about uh
- 21:14so what could this mean for like
- 21:16kind of the day to day decision making
- 21:17when you're treating a uveal melanoma patient
- 21:20and kind of how they decide what therapy to pursue
- 21:23well I think um
- 21:25this this is a a
- 21:26a really good study
- 21:27to mention to your uveal melanoma oncologist
- 21:30and say that you you saw the data
- 21:31and you saw that there was an improved response uh
- 21:34with uh
- 21:35adding immunotherapy to to Hepzato
- 21:38and have a conversation
- 21:41every single patient is different
- 21:42there's gonna be risks and benefits
- 21:43you know for instance
- 21:44we were talking before we
- 21:45we started this conversation about um
- 21:47you know past toxicities
- 21:49may dictate whether or not you're a good candidate
- 21:50or not to restart immunotherapy
- 21:52which is is not a trivial thing to talk through
- 21:54but it's definitely a
- 21:55an area where you should have a
- 21:56a conversation with your oncologist and and
- 21:58and see what may or may not be right for you
- 22:00in terms of standard of care options
- 22:01here in the United States
- 22:03yeah okay
- 22:04well just briefly
- 22:05like what's your opinion on why
- 22:07combining the immunotherapy with Hepzato
- 22:09and you know
- 22:10like cause Hepzato
- 22:12I guess I'll just I'll just summarize
- 22:14and you can correct me or
- 22:15or you can summarize but like
- 22:16you know Hepzato is chemo based
- 22:19and it's specifically localized chemo to the liver
- 22:22we've talked about it a lot here on the podcast
- 22:24we've had lots of webinars and lots of speakers discuss
- 22:26what is Hepzato how does it work
- 22:28so why do you think just kind of opinion wise
- 22:30why do you think doing the Hepzato
- 22:32with the immunotherapy
- 22:33has the promising potential that it shows
- 22:36there's certainly lots of theories behind this
- 22:38and we we kind of
- 22:39get into the big themes of immuno-oncology in 2025
- 22:44and going into 2026 in the last few years
- 22:46we have cold tumors
- 22:47which are essentially tumors where the immune system
- 22:51for multitude of reasons is not getting into the tumor
- 22:54um and then we have hot tumors which uh
- 22:57if we think of like
- 22:57cutaneous melanoma is very immunogenic or
- 23:00or a hot tumor
- 23:01meaning that when you prime the immune system
- 23:03with immune checkpoint inhibitor therapies
- 23:04it's able to do what it's supposed to do right away
- 23:07I think when you think about something like Hepzato
- 23:09we've seen other combinations of chemotherapy with
- 23:12with immunotherapy we've seen other uh
- 23:14drugs such as VEGF inhibitors which uh
- 23:16interfere with the uh
- 23:17vascular angiogenesis or blood vessel growth in tumors
- 23:21and I think ultimately
- 23:22I don't think we have a
- 23:24an exact understanding of the mechanism
- 23:25but it's probably uh
- 23:27that we're the
- 23:28the killing of the cancer cells is
- 23:30is allowing a local inflammatory response
- 23:32that then
- 23:32can be propagated further by the checkpoint inhibitors
- 23:34so it's it's really a synergistic
- 23:36but I think there is a lot to
- 23:38to the understanding of that mechanism
- 23:39that we have yet to figure out
- 23:41yeah for sure
- 23:41I guess like
- 23:42the way that I'm understanding what you said
- 23:43is just basically
- 23:44like the cold tumors of uveal melanoma
- 23:48when they're killed for lack of a better term
- 23:52by the Hepzato it kind of um
- 23:54like they kill the cells right
- 23:56and then the the cells
- 23:57our body has to dispose of those dead cells
- 23:59that's part of like
- 24:00how the cells work I'm like
- 24:02trying to think back to seventh grade biology
- 24:04but when it picks up
- 24:06those dead cells that are cancer cells
- 24:08they're now like
- 24:09no longer invisible they're not cloaked anymore
- 24:11and so the immune system has a better chance
- 24:14I guess of like
- 24:15seeing them so to speak
- 24:17yeah
- 24:17tumor I think
- 24:18we like to think of as a ball of cells
- 24:20that is just growing but it's really not true
- 24:22it really what it is
- 24:23is it's a ball of cells
- 24:24that's growing around dead cancer cells
- 24:26fibrotic tissue like scar tissue
- 24:28it gets very like
- 24:29walled off and matted we
- 24:31we talk about this as the tumor microenvironment
- 24:33and when you think of that
- 24:35you're exactly right when you start
- 24:37you know at least theoretically
- 24:38when you start using something
- 24:39that will break into that environment
- 24:41and release some of these
- 24:42we call them neoantigens or the proteins
- 24:44that the immune system will actually see and attack
- 24:47um we get a better response and
- 24:48and I I think we see that here with the
- 24:50with the Chopin trial
- 24:52yeah absolutely
- 24:53okay well
- 24:54I wanna move on to our next study
- 24:56but like I said you guys like
- 24:57if you're listening and you're like
- 24:58wait wait wait
- 24:58no like
- 24:59tell me more like
- 25:00I wanna hear more about this
- 25:01please tune in to our first quarter webinar
- 25:03we are gonna be covering the Chopin trial
- 25:05in more depth
- 25:05because this is such a clinically relevant
- 25:07set of information that we
- 25:09as patients need to be aware of
- 25:10and that we I mean
- 25:12I just I have
- 25:13I have a lot of hope personally
- 25:14that we're going to see more patients able to
- 25:16kind of enact this similar protocol
- 25:18over the course of their treatment
- 25:20and that we'll
- 25:21we'll see some really good results from it
- 25:23but let's move on to the um
- 25:25IMA203 t cell or the Immatics therapy trial
- 25:29um this is a pretty complex therapy
- 25:31and we're I mean
- 25:33I guess I kind of thought of it as like
- 25:35this is maybe similar to TIL therapy
- 25:38is that I mean
- 25:38is that similar or or not really
- 25:41no um
- 25:42no similar concept so uh
- 25:44the this
- 25:45this study uh
- 25:46was the Presidential Symposium abstract presented by uh
- 25:50Sapna Patel uh
- 25:51from the university of Colorado um
- 25:53who's been really instrumental in in
- 25:54in bringing this therapy forward
- 25:57uh so
- 25:57the IMA203
- 25:59is a prame directed t cell receptor therapy
- 26:02in patients who had previously treated advanced
- 26:06metastatic uveal melanoma so what this therapy is um
- 26:09when we think about tumor infiltrating lymphocytes um
- 26:12what we're doing in that situation is
- 26:14we are lymphocytes
- 26:15being the immune cells that kill cancer cells
- 26:18we are taking tumor out and we're
- 26:21we're taking the immune cells out of that
- 26:23and then we're increasing them
- 26:25and then outside the body
- 26:27and then putting them back in to treat the patient um
- 26:30what t cell uh
- 26:33we we would call these BiTE therapies
- 26:35or bispecific t cell engaging therapies
- 26:38what what we are doing with
- 26:39with these therapies and there's
- 26:41there's a multitude of uh
- 26:42them that are in clinical development
- 26:44across multiple solid tumors
- 26:45as well as uh
- 26:47multiple standard of care um
- 26:48targeted therapies what
- 26:50what it's doing is the there's a protein
- 26:52that's being expressed on the tumor cells
- 26:55this is the prame derived peptide protein
- 26:58and then on the other side of the protein
- 27:00is something that binds the t cells
- 27:02the t cells that are circulating in your body
- 27:04so getting back to that concept of cold
- 27:08tumor micro environments you know
- 27:09I mean when you give a checkpoint inhibitor
- 27:11and the immune cells are not getting into the tumor
- 27:13this is a way to hone the t cells to the
- 27:17the tumor uh
- 27:19and try and propagate that immune response that way
- 27:21very very promising therapy
- 27:23this is a very important study
- 27:25very very interesting results
- 27:27so that is essentially the gist of
- 27:29of the the mechanism of action
- 27:32before we get into the study results
- 27:34how were the patients like
- 27:36who entered the study
- 27:37kind of generally doing from like a
- 27:38I don't know like
- 27:39current disease status or like physical
- 27:41I don't know physical fitness physical health
- 27:44so um
- 27:45the study enrolled 74
- 27:47we would call them heavily pre treated patients
- 27:49which means that they had a median uh
- 27:51or or average three prior lines of therapy
- 27:53so these are patients who have really exhausted most
- 27:57if not all standard of care options uh
- 27:59for for uveal melanoma
- 28:00and the um
- 28:02yeah so
- 28:03so that
- 28:04it was a pretty heavily pre treated patient population
- 28:07uh huh
- 28:08okay so let's talk about these numbers
- 28:10what was our response
- 28:11yeah I guess just
- 28:12just to to um
- 28:15summarize again the study uh
- 28:17was patients with recurrent or refractory
- 28:19uveal melanoma um
- 28:21in solid tumors where they were uh
- 28:23HLA-A0201 positive and prame positive uh
- 28:27and included uh
- 28:28uveal melanomas with prior Tebentafusp responses
- 28:32so the study enrolled as I mentioned
- 28:3474 uh
- 28:35heavily pretreated patients
- 28:36and the most common treatment related adverse event was
- 28:39cytopenias that occurred in almost all patients
- 28:42that were enrolled on the study
- 28:43cytopenia meaning
- 28:44that you have a decrease in your white blood cells
- 28:46your red blood cells or your platelets
- 28:47and then cytokine release
- 28:49syndrome was another important toxicity
- 28:51so what this essentially showed was
- 28:54this is very common
- 28:55across all t cell engaging therapies
- 28:57like this
- 28:58when you give these therapies
- 28:59you create an immune response uh
- 29:01that's a little different than what you would think of
- 29:02with an immune checkpoint inhibitor
- 29:04um
- 29:04you're essentially creating a lot of cytokines in this
- 29:07in a short amount of time
- 29:08and this can lead to low blood pressure
- 29:09can lead to fevers it can lead to um
- 29:11it can be uh quite uh
- 29:14serious uh from a clinical standpoint
- 29:16so we monitor patients very
- 29:17very closely for that
- 29:18so CRS occurred in 95% of patients on the study
- 29:21it was mostly low grade um
- 29:23meaning that it wasn't uh
- 29:24to the point where uh people were clinically unstable
- 29:28um and then of
- 29:29of the most important findings
- 29:31for the uveal melanoma community
- 29:32is that a confirmed
- 29:33objective rate of response was achieved in 67% of the
- 29:36uh uveal melanoma efficacy evaluable patients
- 29:38which was uh 10 out of 15 with one uh
- 29:41patient having an ongoing unconfirmed partial response
- 29:44and then all patients
- 29:4516 out of 16 experienced tumor shrinking
- 29:48which is pretty remarkable if
- 29:50if you if you think of that
- 29:51that to me and I think to the larger community
- 29:53shows that there's definitely a signal there
- 29:55that this is doing something
- 29:56although very very small numbers
- 29:58in a phase 1 studies we talked about before
- 30:00and then the median progression free survival was
- 30:02eight and a half months
- 30:03with a median overall survival of 16.2 months
- 30:06so very very uh
- 30:08important study that is now uh
- 30:09going into the phase 2 portion of the study um
- 30:12and that's gonna be enrolling I
- 30:13I believe it's already enrolling patients
- 30:15yeah that's fantastic
- 30:17um I actually have the
- 30:18the luck of knowing someone who
- 30:20I'm pretty sure is included in this data
- 30:21and she has
- 30:23one of the best response rates
- 30:24that they have in the study
- 30:25and so it's been really cool like to
- 30:27to know that that is um
- 30:29going well for her and I'm
- 30:30I'm thrilled that they're able to continue enrolling
- 30:32because I think for a little while last year
- 30:34it seemed like there was kind of a
- 30:36a lull in in if they were going to continue on with
- 30:40with uveal and so I'm glad they are
- 30:42that's really really um
- 30:43promising to hear
- 30:44yeah yeah
- 30:45very very
- 30:45very exciting data I mean uh
- 30:47I think uh
- 30:49and Doctor Patel presented this uh
- 30:51at ESMO
- 30:52you know seeing
- 30:53response of tumor shrinkage in that many patients is
- 30:55is uh
- 30:56pretty remarkable and
- 30:58and and certainly very uh
- 30:59enthusiastic for for what may be shown in the
- 31:02the larger trial
- 31:03yeah absolutely
- 31:05okay so you mentioned the CRS um
- 31:07common responses like
- 31:08just the common side effects
- 31:10and you also mentioned
- 31:11I don't actually know if we mentioned this like
- 31:13just for the like
- 31:13how this is done um
- 31:16it starts with kind of figuring out and um
- 31:19making the cells but then there's some elements of like
- 31:22chemo and hospitalization that are needed for like
- 31:24doing this treatment is that correct
- 31:26yeah so uh
- 31:28basically you
- 31:29you undergo very similar to TIL
- 31:31as you've mentioned before
- 31:33just slightly different uh
- 31:34you you undergo cytoreduction
- 31:37which is uh
- 31:38or lymphodepletion rather
- 31:40which is basically like
- 31:41you're getting rid of some of the lymphocytes
- 31:42that are there already in your body to
- 31:43to make room for this this infusion of uh
- 31:46lymphocytes then you are hospitalized to
- 31:47to monitor you for that
- 31:49cytokine release syndrome that can potentially occur
- 31:51so it's a little bit different than other therapies
- 31:53and I think
- 31:53something that we have to definitely keep an eye on
- 31:55because when you you think about these therapies uh
- 31:59they're very very promising
- 32:00and they're very very
- 32:01you know offer a lot of hope for the future
- 32:03but
- 32:03we have to think about how to give these therapies to
- 32:05to more and more patients around the country
- 32:07in the world because
- 32:08I do worry that some of these therapies will be
- 32:10isolated to larger centers
- 32:11for a long period of time
- 32:13I mean this is still a clinical trial
- 32:14but you know
- 32:15assuming or hoping that this goes on to become approved
- 32:18that that is definitely a concern
- 32:20yeah absolutely
- 32:21um and I think too
- 32:22like this is one of those treatments too
- 32:25that maybe patients would be like
- 32:27listening and and kind of weighing okay
- 32:29I'm HLA positive I'm prame positive
- 32:31like maybe this would be an option for me
- 32:33this sounds pretty intense
- 32:35um how
- 32:36like as an oncologist
- 32:37do you feel
- 32:37like you can help weigh the intensity versus
- 32:40like the possible benefit
- 32:42like is this something that is an ongoing treatment
- 32:44or is it kind of more of a one time thing
- 32:45I mean it's a one time thing
- 32:46but it's it's
- 32:47it's very um
- 32:49it it is very intensive
- 32:50so I mean it
- 32:50it falls into the realm of cellular therapies where we
- 32:53we do have a high risk CRS
- 32:55we have a high risk uh
- 32:57just by giving someone the
- 32:59the lymphodepleting chemotherapy
- 33:00there's potential complications for that
- 33:02so I mean
- 33:03it really is something where you have to
- 33:06you know talk to your oncologist and and
- 33:07and make sure that you're a good candidate
- 33:10you know any of the centers that are doing things like
- 33:11tumor infiltrating lymphocytes
- 33:13or these trials are are
- 33:14obviously
- 33:15the experts in determining who would
- 33:16and wouldn't be a good fit
- 33:17but um
- 33:18it is not a trivial trial to enroll in
- 33:20and these aren't therapies that are
- 33:21you know
- 33:22necessarily a good fit for everybody
- 33:24yeah for sure
- 33:25um okay
- 33:26well let's move on to the next study
- 33:28this one was really cool and
- 33:29I feel like we could definitely talk about it for ages
- 33:31so I I'm gonna have to come back to that one
- 33:33like with another like
- 33:34another physician or like in a webinar maybe
- 33:36like I just feel like it's really neat
- 33:38yeah but let's talk
- 33:40let's talk about the plume trial
- 33:41which was the pembro
- 33:42is it pembrolizumab and lenvatinib
- 33:47and like kind of
- 33:48I guess the goal of this one is really
- 33:49let's cover some realistic post event of us for
- 33:52Kimmtrak options
- 33:53right so yeah
- 33:55when when we think about uveal melanoma
- 33:57you know once we get into the category of patients
- 34:00that are not as similar to cutaneous oncology
- 34:02with BRAF when we have to divide into HLA positive
- 34:04and HLA negative patients
- 34:05and those that unfortunately
- 34:07don't have HLA-A0201 positivity
- 34:10we we need to well
- 34:12for all patients but
- 34:13you know those that can't get Tebentafusp
- 34:15we're actively trying to think about other new
- 34:18potential therapies so uh
- 34:19this the plume study
- 34:21a single arm phase 2 trial of pembro
- 34:23which is a an immune checkpoint inhibitor
- 34:25and lenvatinib
- 34:27which is a VEGF inhibitor that I had mentioned before
- 34:30so what lenvatinib
- 34:33basically so the
- 34:35the rational behind the
- 34:36the trial is similar to what we were talking about with
- 34:40uh
- 34:40the Chopin trial
- 34:42yes
- 34:43so this is a multi-kinase inhibitor
- 34:44acts on multiple different kinases in the
- 34:45in the cell and
- 34:46and what you're doing is that
- 34:48you're hoping that
- 34:49you're changing the tumor microenvironment
- 34:51in a way
- 34:51that will restructure some of these blood vessels and
- 34:54and allow uh immune cells in
- 34:56so that's this is something that um
- 34:59you know we've the
- 35:01these synergistic combinations have been uh
- 35:04you know thought of and explored for a while now
- 35:06so the the patient was uh
- 35:09or the the study was two cohorts uh
- 35:11assessed HLA-A0201 negative patients
- 35:14and Tebentafusp naive
- 35:15it obviously makes sense to group those together
- 35:18and then HLA-A0201
- 35:19positive patients pretreated with Tebentafusp
- 35:22and then patients received pembrolizumab
- 35:24for a maximum of 35 cycles um
- 35:28standard dosing every 3 weeks
- 35:29plus lenvatinib which is 20 mg a day
- 35:32and then um
- 35:35they had imaging every uh
- 35:37every nine weeks until progression
- 35:38so what the what the study showed
- 35:40was
- 35:40that all patients were followed for more than 27 weeks
- 35:43um and 15 progressions were observed in Cohort 1
- 35:46which was that combination uh
- 35:48corresponding to a 27
- 35:49progression free survival of 31.8% uh
- 35:52cohort 2 uh had 11 progressions in that 27 week period
- 35:57uh with a progression free survival of 60.7% um
- 36:00so the you know
- 36:04difference is there in in
- 36:05in progression free survival for sure
- 36:07but um a very small study with very small numbers
- 36:10yeah you know
- 36:11but also like decent numbers
- 36:14yeah yeah
- 36:15I guess I think that's pretty decent
- 36:16like especially for the cohort 2
- 36:18the pre treated Tebentafusp
- 36:19but even for the people who are HLA
- 36:21cause I know that's that's a common
- 36:23it's just a hot topic in our
- 36:24our community
- 36:25especially since we've gotten Kimmtrak approved
- 36:27is okay sure
- 36:28Kimmtrak that could be great for somebody
- 36:30the HLA positive especially for
- 36:31you know the patients whose trial
- 36:33who can enroll in a trial
- 36:34that is HLA positive and or prame dependent
- 36:37but it kind of feels a little like
- 36:39but what about me right
- 36:40me right
- 36:41HLA O2 negative
- 36:42like what's out there for me
- 36:43this is at least something
- 36:45it's maybe not the highest numbers
- 36:46but it is something and it's
- 36:48I feel like that's that's a pretty significant number
- 36:50the 30
- 36:51it is 30 ish
- 36:5131%
- 36:52it is
- 36:53but um
- 36:54the things to keep in mind
- 36:56is that this was a comparative study
- 36:57it wasn't it wasn't a randomized study
- 36:59so we're not comparing these two groups necessarily
- 37:01it's just a comparison
- 37:02which can kind of be
- 37:03it's their cohorts as opposed to arms
- 37:06and I think it hints the the
- 37:07the fact that we don't have great therapies for
- 37:09for patients in this in this uh
- 37:11category so uh
- 37:13we we are looking for novel combinations
- 37:15and I I think that this
- 37:16this trial fits that so yeah um
- 37:19definitely something to to keep in mind
- 37:21what about like
- 37:22the safety reality of um
- 37:23this combination of like
- 37:25the checkpoint inhibitor and the VEGF
- 37:27the VEGF drug
- 37:28so uh
- 37:28the safety and uh uh
- 37:30the safety was consistent with this kind
- 37:33this is a combination
- 37:34that's been used in other solid tumors already
- 37:36so um not
- 37:38not a complete novel combination on in of itself
- 37:40there was no new or or different uh toxicities
- 37:43lenvatinib is is uh
- 37:45admittedly a pretty tough drug to take uh
- 37:47so uh there's
- 37:49there's uh quite a few potential side effects that are
- 37:52warrant dose reductions and
- 37:54and stopping uh
- 37:54so
- 37:5576% of patients on this trial
- 37:57had to have dose reductions in lenvatinib
- 37:58which is is pretty consistent with
- 38:00with other trials um
- 38:01and then pembrolizumab obviously you have the um
- 38:05the potential for
- 38:06immune checkpoint inhibitor toxicities
- 38:07but nothing that was new
- 38:08or different than what's been demonstrated in the past
- 38:11okay alright
- 38:12so then for for this one
- 38:14what do you feel like
- 38:15is the biggest takeaway from this specific study
- 38:17for us like kind of moving forward
- 38:19I think the the
- 38:20the biggest takeaway for this study is um
- 38:23you know something that warrants further exploration
- 38:28as a combination but also something where if you
- 38:30if you unfortunately find yourself without options
- 38:33something you should talk to your oncologist about
- 38:35and see I mean
- 38:35these are FDA approved drugs
- 38:37that could technically be the rationale if
- 38:40if there aren't another
- 38:42no other standard of care treatment options available
- 38:44you can you can consider this combination off
- 38:46off off label
- 38:47it's not FDA approved and hasn't
- 38:48hasn't undergone a randomized trial
- 38:50but um something to
- 38:51talk about the risks and benefits of doing that
- 38:52with your oncologist
- 38:54yeah absolutely
- 39:26alright well um
- 39:27this next one
- 39:28I just wanna like really briefly touch on this
- 39:30cause I know
- 39:30this does focus a little more on protecting vision
- 39:33but this one is the dur dur
- 39:35oh my goodness Darovasertib
- 39:37I can say it the Darovasertib trial
- 39:39and this one was I think
- 39:41isn't it one of the arms of the Ideaya trial
- 39:43is that the correct term so
- 39:46this one is specifically talking about
- 39:49treating the primary disease
- 39:50meaning the eye itself
- 39:51but what do you feel like
- 39:52the benefits are of something like this
- 39:54being an adjunct therapy that we're seeing numbers in
- 39:57just to give the background
- 39:59um this was a phase 2 study of uh
- 40:01Darovasertib as neoadjuvant therapy
- 40:03meaning before surgery in primary uh
- 40:05uveal melanoma patients
- 40:06requiring either enucleation or uh
- 40:09plaque brachytherapy um
- 40:10and the primary endpoint was uh
- 40:12enucleation prevention meaning that you've
- 40:14you've shrunk the tumor down
- 40:16and you no longer have to go with such a drastic
- 40:19uh surgical intervention
- 40:20so in this uh
- 40:22in the population of patients
- 40:2390 primary uveal melanoma patients
- 40:26received uh
- 40:26Darovasertib at 300 mg twice daily in 28 days cycles
- 40:30the efficacy in the population was
- 40:3359% of patients became eligible for enucleation
- 40:35prevention
- 40:37for patients with available paired simulations and
- 40:40the reduction of the tumor essentially
- 40:43so so
- 40:44so really what what
- 40:45what they showed in
- 40:46in this study was that you can have a
- 40:49a cohort of patients that can avoid enucleation by um
- 40:52giving this therapy so I think
- 40:54you know admittedly a
- 40:56an area that is a practicing oncologist I see less of
- 40:58because I I don't
- 40:59I don't see as many of the
- 41:01the neoadjuvant patients
- 41:02but it's certainly something that
- 41:03your ocular oncologist um
- 41:04and medical oncologist should both be aware of
- 41:07this data because it's a
- 41:08it's important
- 41:09this is something where you could potentially uh
- 41:11reduce the risk of
- 41:12or reduce the need of a very uh
- 41:15intense intervention to treat your your primary disease
- 41:18yeah absolutely
- 41:19I mean this is the kind of trial that like
- 41:20if I go back five and a half years to
- 41:22when I was diagnosed with a massive
- 41:23barely plaque eligible tumor in my eye
- 41:26and knowing like
- 41:27what radiation damage I experienced because of the
- 41:29just the sheer size of the tumor
- 41:32I could see this have you know
- 41:33having been something that could have potentially
- 41:35avoided eventual enucleation
- 41:37for me
- 41:37because if we can shrink the tumor
- 41:39and reduce how much radiation is used to treat it
- 41:42then I mean
- 41:43that would be good
- 41:43I know there's been a little bit of noise
- 41:45around this specific trial
- 41:47and kind of I don't
- 41:48I don't know if they still have this arm
- 41:49I think they did temporarily
- 41:51but like
- 41:51kind of
- 41:51going from the neo adjuvant to the adjuvant setting
- 41:54where they I think
- 41:55were allowing patients to and
- 41:57and don't quote me on this guys
- 41:58but like
- 41:59have you heard of that like
- 41:59where they were like uh
- 42:00patients who who did well
- 42:02neo adventantly
- 42:03they let them keep taking it temporarily
- 42:05yeah taking the Daro drug
- 42:07yeah yeah
- 42:09the the crossover to the other arm
- 42:10basically where you you get adjuvant therapy yes
- 42:13I don't know if anything has been published on that yet
- 42:16OK yeah
- 42:17I'm not sure still more to come
- 42:18more to come for sure
- 42:19what do you think is the potential for something like
- 42:22you know
- 42:22to eventually maybe tap into that adjuvant setting
- 42:25like from an oncology standpoint
- 42:27well I mean I I
- 42:28I think any
- 42:29anytime you're exploring a neoadjuvant therapy
- 42:31that has the potential to reduce
- 42:33the definitive therapy
- 42:35but also may have some role in adjuvant intent
- 42:39therapy to prevent disease recurrence or
- 42:41you know prevent
- 42:42uh
- 42:43distant
- 42:44uh metastasis free survival or
- 42:46or improved distant metastasis free survival
- 42:49I think that's uh
- 42:50that's you know
- 42:51very very important and and
- 42:53and you know
- 42:54gives us a chance to hopefully
- 42:55reduce the amount of patients
- 42:56who need these metastatic treatments
- 42:58yeah absolutely
- 42:59shifting gears guys sorry
- 43:01we're rapid firing through these last few studies
- 43:03but um
- 43:03let's talk a little about the Tebentafusp plus
- 43:06genetics study that
- 43:08I think hopefully
- 43:09can help patients to interpret their own scans
- 43:11and understand their genetics
- 43:13go ahead and just summarize the study
- 43:15and I'll ask questions as they come up
- 43:17yeah so uh
- 43:18this this was a
- 43:19a clinical and molecular outcome study of uh
- 43:22a retrospective cohort of 168 patients
- 43:25uh it was conducted in
- 43:26in uh France
- 43:27and this essentially uh
- 43:29was a collection of clinical and genomic data
- 43:31of metastatic uveal melanoma patients
- 43:33treated between 2018 and 2024 with Tebentafusp
- 43:37so this is a a real world essentially
- 43:39look at Tebentafusp
- 43:41overall rates of response and progression free survival
- 43:44and overall survival so among 168 patients
- 43:47including
- 43:4818 patients that were part of immunocore's
- 43:52IMCgp 100-202 Early Access program
- 43:55so that they would have gotten Tebentafusp
- 43:57before full approval
- 43:59Tebentafusp was first line treatment
- 44:0083% of those patients uh
- 44:02median follow up was 20 months uh
- 44:04with progression free survival of 3 months
- 44:05and a 20 month overall survival rate with a 67%
- 44:09over or uh sorry uh um
- 44:12the 20 month overall survival rate was 67%
- 44:14and the overall rate of response was uh
- 44:168.9% uh and 46% of patients had stable disease
- 44:22so patients with extrahepatic metastasis
- 44:24which was very small amount
- 44:25as you know with uveal melanoma
- 44:26only four in this study uh
- 44:27which is consistent with what we know about the disease
- 44:30had the best outcomes interestingly
- 44:32while those with hepatic disease only
- 44:33or hepatic or extrahepatic disease mixed
- 44:36had shorter progression free survival um
- 44:39and then the study also correlated
- 44:41some of the genomic information into this
- 44:43so trying to correlate you know
- 44:45what we know genomically about tumors
- 44:46with some of these outcomes
- 44:48and it showed that BAP1 and SF3B1 mutations
- 44:51were associated with shorter progression free survival
- 44:54uh median five and eight months respectively
- 44:56and overall survival uh
- 44:58median wasn't reached in the BAP1 group
- 45:01and 27 months in the SFB31
- 45:05SF3B1 group
- 45:06respectively
- 45:08um and then uh
- 45:09disomy 3 tended to be correlated
- 45:11with longer progression free survival of 8 months uh
- 45:13and overall survival of 30 months
- 45:15versus monosomy 3 uh
- 45:17with a progression free survival of 3 months
- 45:19and overall survival of 28 months um
- 45:21so the findings basically
- 45:23is a real world cohort of patients
- 45:24that get treated with Tebentafusp
- 45:25looking at their overall rates of uh
- 45:28response survival
- 45:28impression for survival um
- 45:30and then some of these stratification groups to
- 45:33to try and uh determine if there's any genomic markers
- 45:37that are particularly uh
- 45:39important in uh determining um
- 45:42the outcomes
- 45:43okay so from this like
- 45:44what should patients especially patients who are
- 45:47you know
- 45:47entertaining Tebentafusp or Kimmtrak as an option
- 45:49what should they know when they hear
- 45:51stable disease instead of shrinkage
- 45:53like why should that still be kind of like
- 45:55I mean like
- 45:56why should that still be a good thing I suppose
- 45:59when when we think about things
- 46:00there's a few things I would mention about this study
- 46:02um one is a retrospective study is
- 46:06is not as robust as a prospective clinical trial so uh
- 46:09the data has limitations
- 46:11and then you know
- 46:13when we think getting to your question
- 46:14when we think about things like stable disease
- 46:17and uh
- 46:18response stable disease
- 46:20meaning
- 46:20the tumor staying the same and not getting larger
- 46:22or spreading to new spots
- 46:23is considered I mean we
- 46:24we consider that the treatment working
- 46:26so I I think
- 46:27you know unfortunately we
- 46:28we would love it if we gave a therapy
- 46:30and all the tumors everywhere went away
- 46:32it was gone but that's
- 46:33that's not the case with metastatic disease
- 46:35so stable disease
- 46:36is something that we would think of
- 46:37as a favorable outcome
- 46:39OK awesome
- 46:40obviously
- 46:41definitely consider talking with your local oncologist
- 46:44or you know
- 46:44if you happen to be close to Matt
- 46:46go check him out he's over at the
- 46:47the Rhode Island
- 46:49uh Providence Clinic right
- 46:50Brown University in Providence Rhode Island
- 46:53okay yeah um
- 46:54like we said he's in the physician finder
- 46:56so if you're in the northeast area
- 46:57and you need a treating physician
- 46:59like definitely
- 47:00definitely check out the physician finder
- 47:02it's like
- 47:02one of my biggest pet peeves
- 47:03when patients feel like they have to trial
- 47:05to go and just at least like
- 47:07establish care um
- 47:08because I mean
- 47:09I think I think you could acknowledge too that like
- 47:11it's pretty common in uveal melanoma for like
- 47:13patients to maybe have an established place
- 47:16and then to potentially travel elsewhere if a trial
- 47:18like necessitates it
- 47:19but right
- 47:20anyway so I do think it's
- 47:23it's important though that like
- 47:24I think I've talked about this since the very
- 47:26very beginning of doing this podcast is like
- 47:28how important it is to have a medical oncologist
- 47:31who knows and is up to date about uveal melanoma
- 47:34like
- 47:34not just your run of the mill medical oncologist who's
- 47:37like sure
- 47:38like join my patients
- 47:39like somebody who specializes in this
- 47:41somebody like
- 47:42you know like you who's staying in the know about like
- 47:44data like this
- 47:45okay yeah
- 47:46no I
- 47:46I think the the
- 47:47these have been a very important studies to talk about
- 47:49for all of oncology um
- 47:51it's getting more and more nuanced and and
- 47:53and complicating so um
- 47:54I think we we have to keep all of that in mind
- 47:58when you're seeking out specialists and
- 47:59and second opinions
- 48:00and third opinions are never a bad idea
- 48:01when you have a disease like this
- 48:02so
- 48:03yeah for sure
- 48:04okay well
- 48:05let's chat about this very last one
- 48:07and then we will wrap it up for the day
- 48:08um but this one was
- 48:09I think a Quisinostat
- 48:11is that how you say it um
- 48:13Quisinostat study
- 48:13and it was focused on prevention and palliative care
- 48:16I guess can you
- 48:17from your standpoint as a medical oncologist
- 48:20can you define palliative care
- 48:21because I think that it gets really
- 48:22really confused and mixed up um with hospice care
- 48:26palliative care is
- 48:27is sometimes synonymous with supportive care
- 48:29and palliative care is something that a lot of patients
- 48:32to your point
- 48:32they think that
- 48:33it means that you're being enrolled in hospice
- 48:35which is also in a very under
- 48:36are poorly understood program
- 48:38but palliative care is really supportive
- 48:41so they they help with adjustment to disease
- 48:43because we know that um
- 48:44these are very very tough things to go through
- 48:47getting diagnosed with something like uveal melanoma
- 48:49emotionally physically
- 48:50spiritually
- 48:52and they can provide support there
- 48:54pain management is another huge area of what they do
- 48:58and just overall symptom management
- 49:00so um
- 49:01you know
- 49:01we've shown time and time again that patients who uh
- 49:05have early access to palliative care uh
- 49:07tend to uh
- 49:08do better overall um
- 49:10in terms of their symptom management
- 49:11and also they they have longer survival
- 49:13so um
- 49:14that that
- 49:15those are very important things that if
- 49:16you know your oncologist wants to uh
- 49:18incorporate the the help of a palliative care colleague
- 49:21it's a very very um
- 49:23you know it it
- 49:23it can really really help
- 49:25yeah okay
- 49:26I think that makes sense and I
- 49:27I mean I
- 49:27I love that idea um okay
- 49:29so let's talk about this Quisinostat prevention trial
- 49:32and like
- 49:32kind of what was the goal of it
- 49:33and
- 49:34what ended up being the survival trends that are there
- 49:37there was two last abstracts we're gonna talk about
- 49:39one is the the phase 2 study of uh
- 49:41Quisinostat
- 49:42for higher risk of melanoma
- 49:43and then the other was
- 49:44early integration of palliative care into metastatic
- 49:47ok so two separate things sorry
- 49:48briefly touch about the palliative care study
- 49:50this study randomized in a 1 to 2 fashion in France um
- 49:54a control group where palliative care was introduced
- 49:57per guidelines and an experimental group
- 49:58where palliative care visit
- 50:00started the announcement of metastatic disease
- 50:02by the oncologist
- 50:03and then continued alongside systemic treatment
- 50:06for one year
- 50:07and then the main objective was
- 50:09primary endpoint is to compare psychological needs
- 50:11at six months after randomization
- 50:13just because uh
- 50:14we're running short on time um
- 50:16jump to the conclusion we could
- 50:17we could revisit it in the future
- 50:18but overall
- 50:19there were no difference in the primary endpoint
- 50:20at six months
- 50:21and the further analysis is ongoing
- 50:24with a median follow up of 12 months
- 50:25uh there is a trend for better overall survival
- 50:28in the experimental group
- 50:28so I I think the takeaway is that
- 50:31while this study has its own nuances
- 50:33early intervention of palliative care is is generally
- 50:36very favorably thought about
- 50:37of these patients
- 50:39and it does show a increase overall survival
- 50:41so while people think palliative care I'm I'm
- 50:43I'm dying now it's not
- 50:44not true um
- 50:46so
- 50:46definitely something to talk to your oncologist about
- 50:48and and
- 50:49you know understand that a little bit more
- 50:51no I love that
- 50:52and I think like you said
- 50:53like it's just so important to have that discussion
- 50:54and to not be afraid of it
- 50:56because it really it sounds like it
- 50:58it has a much more favorable way of just giving you
- 51:02you know
- 51:03if you want to live your life well with stage 4 cancer
- 51:05like why not actually use all the tools to do that
- 51:07that's kind of the way that I would look at it
- 51:09right right
- 51:10exactly exactly
- 51:12okay alright
- 51:13well our last study then is the Quisinostat
- 51:15let's just like jump in there
- 51:16I know it was really pretty um
- 51:18pretty short um
- 51:20in terms of what was there and what did they study but
- 51:22but I know this one is I
- 51:23I think still kind of in the midst of continuing
- 51:25so um
- 51:26what do they know so far
- 51:28Quisinostat is basically a
- 51:29a study looking at prevention in uveal melanoma
- 51:33tumors and for background
- 51:35tumors are classified as low risk or high risk
- 51:37metastatic categories
- 51:38based on their Gene Expression Profile
- 51:41uh so this was an open label
- 51:42multicenter investigator initiated study
- 51:44it's phase 2 study to evaluate the effect of adjuvent
- 51:47Quisinostat treatment
- 51:48in high risk uveal melanoma patients
- 51:49on distant metastasis free survival at 36 months
- 51:52this is a trial in progress
- 51:53so this is something that's going on
- 51:55there's not really much data yet
- 51:56but essentially
- 51:57they're going to be looking at this as a potential um
- 52:01adjuvant treatment
- 52:02after definitive therapy in high risk groups
- 52:04to try and see if they can reduce the
- 52:06the development of metastasis in the liver
- 52:08which is one of the more important things
- 52:10there's not much to report on in terms of data
- 52:11but I think it's something
- 52:12we should definitely keep our eyes on
- 52:13in terms of whether or not
- 52:15there are any early safety concerns with the drug
- 52:18and I think we're always away from knowing any of the
- 52:22outcomes in terms of distance
- 52:24metastasis free survival but hopefully in the future
- 52:27we'll have some more information on that
- 52:28yeah absolutely
- 52:29well we have covered a lot
- 52:30you guys so if you've been listening
- 52:32and you've been taking notes or like
- 52:33hitting pause like
- 52:34feel free to come back to this
- 52:35listen to it later this will be available and
- 52:38and I think you know
- 52:40one of the maybe challenging things is like
- 52:42even now there's more studies that are coming out
- 52:45there's more like
- 52:45upcoming clinical trials
- 52:47that are starting to open for enrollment
- 52:49so just stay tuned like the
- 52:50you know the research is definitely making waves
- 52:53even though it can feel like sometimes
- 52:55it's not moving fast enough
- 52:56for those of us
- 52:57who are dealing with metastatic disease
- 52:59but what do you feel like just kind of to close
- 53:01Doctor Hadfield what do you feel like
- 53:02patients should take away from this kind of
- 53:04overall research wave um
- 53:06and the you know
- 53:06just the importance of clinical trials
- 53:08I think when you think about uveal melanoma
- 53:11particularly it's a
- 53:12a rare disease
- 53:13tapping into an advocacy network
- 53:15tapping into a physician finding networks to try and
- 53:18you know find specialists is really critical
- 53:20there is thankfully
- 53:22so many um
- 53:23new and exciting therapies that are in development
- 53:26but as of now and for the foreseeable future
- 53:29a lot of these
- 53:29are gonna be in the realm of clinical trials
- 53:31so um
- 53:32you know if you have questions about clinical trials
- 53:34whether or not it's how they're conducted
- 53:36what the phases are what the details involving them are
- 53:40it's important to talk to your oncologist about
- 53:41anytime you're being treated with the disease
- 53:44you should really make sure you understand
- 53:46what the clinical trial landscape is
- 53:47and whether or not
- 53:48there may be a trial that's a good fit for you
- 53:49because you know
- 53:51these really are the most promising therapies
- 53:53and that's born out in these results
- 53:54that we got from ESMO
- 53:55yeah absolutely
- 53:56well I mean
- 53:56I just remember when the ESMO studies all came out
- 53:59and we saw this like we um
- 54:00our our clinical um
- 54:03I'm trying to our I guess
- 54:04our main science person Kevin
- 54:06who goes and he like
- 54:07observes and and goes to all of these conferences
- 54:10and
- 54:10kind of brings back the biggest takeaways for patients
- 54:12he was so excited after this set of
- 54:14of results and this was probably one of the
- 54:17the highest level of like
- 54:19or the highest quantity of
- 54:20studies published around uveal melanoma
- 54:22like all at once
- 54:23um so I think we were
- 54:24we were all really pretty excited about that
- 54:25so thank you for helping just add to that excitement
- 54:28and break this down for us
- 54:29in a little bit more of a patient friendly way
- 54:32yeah thank you for taking the time out of your day here
- 54:34in the beginning of January
- 54:35we're so glad that we're at the beginning of 2026
- 54:38and it'll be exciting to see where this year goes
- 54:40yeah no absolutely
- 54:42I I
- 54:42this is exciting data and
- 54:44and hopefully
- 54:44it means new and better treatment options for
- 54:46for patients like yourself
- 54:47so thank you for for talking
- 54:48yeah of course
- 54:49okay so like I mentioned
- 54:50throughout this episode
- 54:51you guys make sure to check out the show notes
- 54:53check out the description
- 54:54and please head to our website
- 54:55especially if you want to download this PDF
- 54:57that has the breakdown of all of these
- 54:59you're welcome to print this
- 55:00and bring it to your oncologist office
- 55:01if you choose um
- 55:02just like
- 55:03just show them I mean
- 55:04I think that's one
- 55:05of the things that can be tricky as a patient
- 55:06is to kind of embrace that area of
- 55:09I can be my own advocate but it really is valuable
- 55:11I have not yet met any doctor
- 55:13who's had any problem
- 55:14with me bringing something to them
- 55:15and saying hey
- 55:16what about this like
- 55:18this is part of the let's think outside the box and
- 55:20and work together to figure it out
- 55:22absolutely
- 55:24okay alright
- 55:25well thanks for joining us again
