Dr. Diwakar Davar and Dr. Jason Luke, both of the University of Pittsburgh’s Hillman Cancer Center, highlight key advances in early phase therapeutics and immunotherapy that were featured at the 2022 ASCO Annual Meeting and also address toxicities, including immune checkpoint inhibitor-associated myocarditis.
TRANSCRIPT
Dr. Diwakar Davar: Hello, and welcome to the ASCO Daily News Podcast. My name is Dr. Diwakar Davar, and I’m an assistant professor of Medical Oncology, specializing in melanoma and phase 1 therapeutics at the University of Pittsburgh’s Hillman Cancer Center. I am the guest host of today’s podcast. My guest today is Dr. Jason Luke, a colleague and the director of the Cancer Immunotherapeutics Center at the UPMC Hillman Cancer Center here.
Today, we’ll be discussing advances in early-phase therapeutics and immunotherapy that were featured at the 2022 ASCO Annual Meeting.
You’ll find our full disclosures in the show notes, and the disclosures of all guests on the podcast are available on our transcripts at asco.org/podcasts.
Jason, thank you for coming on the podcast today.
Dr. Jason Luke: Thanks so much for the invitation. It was a great ASCO, and I hope everyone had a good time.
Dr. Diwakar Davar: So, onto our abstracts. So, the first one that we’ll be discussing, and Jason as you know we’ve done this before. We’ll be rapidly transitioning between phase 1 therapeutics, melanoma, and advanced phase 2 and 3 trials, but you know this is something you do very well. So Abstract 2504, it’s a phase 1 trial of TIM-3 inhibitor cobomilab immunotherapy and in combination with PD-1 inhibitors nivolumab and dostarlimab. The AMBER Trial that was presented recently, and in full disclosure, both you and I actually are on this abstract. So, what do you think of this abstract? What do you think of the data that is discussed, and how do we contextualize this in relation to what needs to be done in this space?
Dr. Jason Luke: So, I think this is an exciting abstract because it brings forward what may be the next high-priority immune checkpoint to try to target in clinical oncology. To level-set, I think everybody listening will know about PD-1 and CTLA-4 as immune checkpoints. In the last year, we’ve had LAG-3 come forward as now a standard of care element of armamentarium in melanoma, and we look forward to further studies of LAG-3 and other tumor types as we think it should be a good partner where PD-1 is otherwise approved.
So here now, we hear about TIM-3, which is another negative regulatory checkpoint on a number of different immune subsets. And in this abstract, the antibody targeting TIM-3 was cobolimab. So, TIM-3 is a very interesting molecule. It has, what you might call, pleiotropic effects in the immune system. So, while in the context of this abstract, it was being targeted as another immune checkpoint on T cells, it’s important to point out that TIM-3 has other regulatory roles in other immune subsets such as myeloid cells and very particularly dendritic cells, and that’s important because it might bring in another element of the innate immune system to try to drive anti-tumor responses. So, it’s an exciting target because it might be able to expand the groups of patients who could benefit from immune checkpoint blockade.
So, in this abstract, we see initially the phase 1 data of combining cobolimab, anti-TIM-3 with anti-PD-1 of a couple of different flavors. And what you could take from this abstract is that in the phase 1 setting, the drug was well-tolerated and combined well, and had pharmacokinetic properties that would be consistent with what we’d expect for this kind of a monoclonal antibody. I think we have to marry this abstract, which is really the phase 1 data about safety in pharmacokinetic (PK) to another abstract presented in the melanoma session, which showed an expansion cohort of patients who got cobolimab plus nivolumab or dostarlimab.
And there we did see a 50% response rate, albeit that there was heterogeneity of patients being treatment naïve versus treatment-experienced. So, what I would say to this on a high level is that I think these data are preliminarily exciting, suggesting that further investigation into TIM-3 may be valuable in terms of expanding the population of patients initially in melanoma, but there will data coming soon in lung cancer and in other tumor types with another novel checkpoint. And I think if we think ahead into the future, the question is probably going to end up being, which combinations of checkpoints for which patients. That’s pretty exciting to think about. We’ve seen a lot of data of PD-1 plus other molecules, and I think some future biomarker stratification really will be necessary to know which patient would benefit the most from which of these combos, but for the time being, this is exciting data to see where the field is going to go over the next couple of years.
Dr. Diwakar Davar: Great. And I guess, to your point, one important thing to highlight from the abstract is your point about the role of the different compartments. There was actually a very interesting dose-response relationship with the highest dose of the drug not necessarily being the most effective dose, suggesting that yes, as you escalate, you may have different effects in different compartments, and maybe therefore a broad selection of doses might be required to ensure that you have optimal engagement of the optimal target.
So, the next abstract is Abstract 3007. This is the tumor-agnostic efficacy and safety of erdafitinib. So, we now know that FGFR pathway aberrations are found from 77% of all malignancies, FGFR targets are now U.S. Food and Drug Administration (FDA) approved in cholangiocarcinoma with pemigatinib, infigratinib, and as well with erdafitinib metastatic urothelial cancer. We know that these agents are not necessarily effective tests in 1 tumor type because these alterations have risen in multiple tumor types. So, the RAGNAR trial, looking at this across multiple tumor types, what do you make of the interim analysis result presented by Dr. Loriot?
Dr. Jason Luke: So, I’d say that this is probably the future of targeted therapy. And so, I think that where we have activity in 1 disease, it’s very likely we would have activity in others. So, the author has described this as the largest basket trial of a molecularly defined subset that’s been pursued to date. There are upwards of more than 200 patients in the study. I think it’s really important, as we think about the data, to realize, though, that all FGFR alterations are not exactly the same thing. And so, in this study, they gave erdafitinib to patients with solid tumors of any FGFR altered status. And so that’s FGFR1, 2, 3, 4 mutations or gene fusions. And that’s a lot of heterogeneity in there actually.
And in this study, there were two-thirds fusions and one-third mutations, mostly in FGFR2 and 3. That will become relevant as we start to think about the results. On a high level, I have to say that it is impressive in pan-cancer fashion, just selecting by FGFR alteration, there’s about a 30% response rate observed. I think that no matter what, that’s going to be valuable considering these were patients with refractory tumors with 3 lines of prior therapy on median. I think what we need to know more is the breakdown of which specific molecular alteration and FGFR in which tumor types drove most of the benefit.
So, for example, in bladder cancer where erdafitinib is already approved, that’s almost entirely an FGFR3 fusion setting. So we know the drug is effective there. And so I think there will be a further breakdown of the data. As it matures more, you really start to tease out, is it really the case that any FGFR alteration can be treated or there are some that really ought to be the high priorities that we really ought to be going after. I think it would be remiss not to also note, however, that while there’s excitement about this sort of pan-cancer approach, the current generation of FGFR inhibitors are not exactly the easiest drugs to take.
And so, the in-class, hypophosphatemia and stomatitis really does lead to dose reductions in a lot of the patients. And I think that that’s probably really important to emphasize is that despite the pan-tumor activity, there’s still a lot of potential in this field to refine further because it’s almost certainly the case that if we had less off-target toxicity, so to say, we could improve the efficacy beyond that 30% that we saw here.
All the same, I think this is exciting for the concept of a pan-cancer tumor agnostic sort of approach, and we’ll really look forward to more data to come from this study over the next, hopefully, few months.
Dr. Diwakar Davar: And I guess 1 corollary to that is that we now need to start looking for FGFR alterations in multiple tumor types. So, tests, tests, tests. All right, Abstract 3004, phase 1a/1b dose escalation and expansion study of the MDM2-p53 antagonist BI 907828 in patients with multiple solid tumors including advanced, metastatic, liposarcoma. So, we’ve recently had data of the previously undruggable KRAS, and now we’ve got previously undruggable p53, for which we now have targets. So, Jason, what do you make of the p53 targeting approach, in this case, using MDM2 and this particular drug from Boehringer Ingelheim?
Dr. Jason Luke: So, I think that this is an exciting abstract exactly for the reason that you mentioned, which is that p53 has been, and unfortunately, to some degree, still remains, one of those holy grails but undruggable targets in oncology. So MDM2, for those who are listening but might not be aware, is a negative regulator of p53. So, the concept here then is if you drug it, you might release p53 to reactivate activity in that pathway, and then p53 being the guardian of the genome, so to say, potentially leading to apoptosis of cancer cells.
And so, this drug binds MDM2 and MDM2 can be amplified as a resistance mechanism in p53 and several tumor types. And so here, they showed data for the early part of a clinical trial investigating the small molecule, BI 907828, but then they focus specifically in liposarcoma, which is a disease known to be an MDM2 amplified. And so, the results were pretty interesting. The toxicity of this kind of an approach, just to note, is really in class. It leads to some gastrointestinal (GI) toxicities as well as hematologic problems, and this goes again for most regulators of the cell cycle will have these effects, whether they’re CDK inhibitors or MDM2 or p53 modulators.
But I think what was very interesting, this is a disease liposarcoma where chemotherapy, functionally speaking, has no role. We, unfortunately, give it to some patients sometimes, but it has almost no activity, and they observe that in poorly differentiated liposarcomas, the response rate was about 12%, but the stable disease was quite durable. And so, I think that really is potentially a big deal because this is an orphan disease. It really lacks any other treatment. But as you zoom out from that, if you start to think about targeting amplified MDM2 in other settings, I think the activity that we see here is intriguing, and potentially suggests that we may be coming to a future where we’ll have multiple, sort of, orthogonal approaches after reactivating p53. There were actually other abstracts at ASCO Annual Meeting of other molecules that were less mature also along this line.
So, I think, very exciting to take away from this, one, a potential treatment for liposarcoma for all of those patients that anybody listening actually sees, but secondarily this concept of targeting p53, which I think we’ll see a lot more of over the next couple of years.
Dr. Diwakar Davar: Excellent. Moving on to the Abstract 3002, this is a phase 1, two-part multicenter, first-in-human study of DS-6000a of an antibody-drug conjugate comprising the anti-CDH6 IgG1 monoclonal antibody that is attached to a topoisomerase I inhibitor payload via a cleavable linker. And so basically, a way in which you can give topoisomerase: (1) TOP1 inhibitor, (2) CDH6-expressing cells. This was studied in advanced renal cell carcinoma (RCC) and advanced ovarian cancer in this abstract presented by Dr. Hamilton. Jason, what do you think of the results and what do you think of this approach in general, this antibody-drug conjugate (ADC) approach using novel targets as well as novel payloads?
Dr. Jason Luke: I think this is one of those that you can’t help but be pretty excited about, and I think in the context of the data shown at the plenary session in breast cancer for antibody-drug conjugates (LBA3), I think this is really where the field is going to start to go. So, you mentioned that this is an antibody-drug conjugate that targets cadherin 6 or CDH6, which people will remember from biochemistry class and medical school, or something is a cell-cell adhesion molecule, really a basement membrane protein. So, the concept of targeting it really is just to go after a latch mechanism to get the molecule into the tumor where you want. And CDH expression is very high in renal cell carcinoma, upwards of 80% of samples, also high in ovarian cancer, which is why they chose those 2 tumors to go after.
So, the ADCC, and you described its structure just a little bit, but it’s essentially the same backbone as trastuzumab deruxtecan, which we saw this outstanding activity for HER2 and breast cancer on the plenary, with these 8 chemotherapies moieties attached to it, but here now, targeting it instead to HER2, with this molecule now to CDH6. And I think, again, you can’t help but be impressed. There were treatment responses on almost every dose level of the dose escalation in this study. There’s in fact only 1 patient whose tumor was not, at least, stable disease or a PR, and I think that that just goes to show the power of truly bringing the chemotherapy in a targeted manner into the tumor microenvironment. Responses were heterogeneous. They were not super deep responses per se, but the stable disease was quite durable in the study, and the patients were going out more than 7 months. And again, realizing this is at the lower dose levels as we’re increasing the dose and move this in their earlier lives of therapy is likely to be even more effective.
They did show a waterfall plot of the reduction in CA 125 for the patients with ovarian cancer that really looked quite impressive. And given that that’s our clinical biomarker that we commonly follow, it may actually even more indicative of the benefit we would see as opposed to resist.
Now, again, there is some toxicity. It is a chemotherapy moiety that’s conjugated to the ADCs. So, the most common toxicities were nausea, vomiting, and low platelet counts, but these are kind of toxicities that we’re quite accustomed to with chemotherapy. Just to summarize, I think there’s a lot of promise for this kind of antibody-drug conjugate targeting, and I think it can only be impressive that they had this amount of activity in the dose escalation of the study. [I] very much look forward to the expansion cohorts in renal and ovarian, which we’ll presumably expect to see later this year, early in the next year.
Dr. Diwakar Davar: And as you alluded to, this really was parallel that ASCO, by the standing ovation given to Dr. Modi when she presented the DESTINY04 data of trastuzumab deruxtecan in HER2-low breast cancer, basically now redefining breast cancer from 4 camps, now we have to think of not just HER2 amplified or HER2-high, but also HER2-low. So yes, really have to now rethink how we classify these diseases (LBA3).
So Abstract 2509, the efficacy of anti-PD-1/PD-L1 immunotherapy in non–small cell lung cancer dependent based on CD8 and PD-L1 status. So really Dr. Galon taking us into what he has now described as the immunoscore—really a way of characterizing tumors. A way of thinking about tumors that you’ve also championed, Jason, in terms of this T cell-inflamed and uninflamed hypothesis. So, tell us a little bit about how these jives with your work and how you would think about lung cancer patients responding and not responding to immune checkpoint inhibitors (ICI) therapy in this context?
Dr. Jason Luke: Yeah. I think the focus quickly here on the immunoscore, so the people are aware of that, I think is really important for diving into these specific results. You have to realize our fundamental underlying predicate for immune checkpoint blockade inhibitor response is that patients have mounted an adaptive immune response. So, CD8 T-cells have gone into the tumor where they elaborate chemokines and cytokines like interferon gamma, which upregulates the expression of PD-L1 in the tumor but also in the surrounding immune cells.
So, you realize that even though antibodies are targeting PD-1, it’s really that we’re targeting that tumor microenvironment. So, the more robustly we can measure that, and we understand it, the more likely we are to know whether or not the patient is going to benefit. So, this is where the immunoscore comes in. The immunoscore is actually a fairly simple test. It’s one slide, immunohistochemistry slide where they can stain jointly for CD8 and PD-L1 on the same slide. And that allows them to do a number of different things beyond just testing the total level of PD-L1. They can test the CD8 density, the PD-L1 expression, but then also the interaction between CD8 T-cells, their distance from each other, from PD-L1 expressing cells, and so on and so forth.
And so really [this] can give us a much more robust analysis of what all is going on in the tumor microenvironment again, off of a single slide. So here then, in this abstract, for patients with non–small cell lung cancer receiving anti-PD-1, they then compared the utility of only PD-L1 testing versus doing the immunoscore. And so, it was actually quite a large set. They had about 250 patients in their analytical set and then split about 150 or 180 or something into the training and validation sets, and they compared the immunoscore against 2 different standard PD-L1 antibodies, the 22C3 as well as the SP263. And what they saw was a high concordance for expression between PD-L1 and the immunoscore.
That’s good, because, again, they’re measuring PD-L1 in both of those. And so that was a good, sort of, level set. The immunoscore, however, allows them to look to 7 different parameters, again, beyond just PD-L1, as I mentioned. So, CD8 density, interaction, distance, and this kind of thing. Then in these test and training cohorts, they were able to actually split out patients who are PD-L1 positive into further groups, those that were immunoscore low and that were high. And in so doing, they were actually able to sort of dramatically predict the likely progression-free survival on PD-1 checkpoint blockade in those different non–small cell lung cancer groups.
So why is this important? Selection of patients by PD-1 has been very useful in the field of non–small cell lung cancer, but it’s hardly a panacea. You’re not at all assured your patient is going to do well just because they’re PD-L1. And here comes a second assay that can be done in a standard of care setting. So, the immunoscore is a test. You could just order it, and that really does give you much more predictive power about who’s likely to do well and who isn’t. And I think this test and more broadly multi-spectral imaging is really going to become a core component to how we risk stratify and predict outcomes to checkpoint blockade and lung cancer, but broadly in other tumor types over the next couple of years.
Dr. Diwakar Davar: Okay. Now, moving on from a biomarker for PD-L1 and PD-1 to a setting in which PD-1 was just recently U.S. Food and Drug Administration (FDA)-approved, so I’ll give a brief background to the trial that you’ve actually developed and led. And so, this is KEYNOTE-716, the abstract in question is LBA9500 (late-breaking abstract) 9500, but this is the distant metastasis-free survival (DMFS) data readout. The DMFS, distant metastasis-free survival with pembrolizumab versus placebo in the adjuvant setting for patients with stage IIB or IIC, that is high-risk node-negative melanoma and the data from the phase 3 KEYNOTE-716 study.
So, this data, at least the recurrence-free survival (RFS) data was actually earlier published, you had presented it earlier last year and also more recently this year, but it was published recently in Lancet. And we know that 716 is a study in which, for the first time ever, we have an immune checkpoint inhibitor PD-1 that was studied against placebo with the high-risk node-negative setting in stage IIB and C melanoma, demonstrated a significant RFS benefit in the setting against placebo. And now we have the DMFS readout.
Maybe you could tell us a little bit about both the RFS and the DMFS data, and why this is such an important advance for these patients.
Dr. Jason Luke: Thanks. And I agree this really is a sea change in how we thought about stratification of patients with melanoma, but I think this broadly has implications for other tumor types as well. So, in melanoma, we’ve historically thought of its involvement of the lymph nodes—stage III as being the high-risk disease, but we also, if you look at the outcomes from the AJCC, we see the patients with stage IIB and IIC, so deep primary lesions, actually have similar bad outcomes as those patients with stage IIIA and IIIB. And so anti-PD1 and adjuvant therapy and melanoma were originally proved for stage III, but having understood that about 5 years ago actually, started to think, well, why not also treat the patients with stage II if they’re at similar risk.
And we pursued KEYNOTE-716 as you mentioned, and it read out last year as a positive trial for recurrence-free survival. And the abstract here then was to look at the impact on distant metastasis-free survival. So, while the regulatory consideration for approval, and it is approved and it’s available for patients now, was based on relapse, what we really want to be preventing is the development of metastatic disease because presumably that would correlate with the eventual death of the patient from cancer.
So, in the abstract here, we see the first update for DMFS, which also was positive on its first analysis, the hazard ratio at 0.64. And so, again, very similar to the RFS benefit, showing about a 35-36% reduction in distant metastasis-free survival. And this is a theme that we’ve seen across adjuvant studies in melanoma, all the adjuvant studies in fact, is that the RFS improvement, the relapse-free survival hazard ratio mirrors very closely the distant metastasis-free survival ratio. We saw that again here. I think it just emphasizes that anti-PD-1 immunotherapy is highly effective in melanoma no matter what stage it’s in, but rather related to the risk of death for melanoma.
And so this really has a practice changing in the field of melanoma oncology. Patients need to be referred to medical oncology early for discussion around risk stratification and consideration of adjuvant therapy—I think even at the same time that they’re having resection of their primary lesion, and it even calls into question of whether or not we should even fully be doing procedures like sentinel lymph node biopsies any longer, considering we can make the decision to give adjuvant therapy now based on the primary—albeit that’s a controversial area of discussion.
And I would just love for this to start to penetrate into other disease settings. We’ve seen more recently, approval for neoadjuvant therapy in lung cancer and we see in kidney cancer, bladder cancer. We see adjuvant therapy in—I think we’re going to see immunotherapy starting to become an important part of the armamentarium in these hard-to-treat cancers, even at the time that perioperatively before or after surgery.
So definitely a major change in the way we’re thinking about stratifying patients and emphasizes that you need to get those patients with melanoma in to have that discussion around adjuvant therapy probably at the time of the primary lesion resection.
Dr. Diwakar Davar: And finally, Abstract 2507, single-cell profiling of human heart and blood in patients with checkpoint inhibitor-associated myocarditis. So, this is data from the NGH Group, Dr. Villani and colleagues are presented by Dr. Blum. We know that myocarditis is an uncommon but very serious immune related adverse event (irAE), and here in this particular dataset, this group which has done a lot of underlying work to really uncover the role of certain key phenotypes, cellular phenotypes, in the development of myocarditis it's presenting the data in the context of ICI-related myocarditis. So, what do you think of this data, what do you think of the use of checkpoint inhibitors are now, as you’ve said, migrated linear in the lifecycle of the patient, what do we need to be thinking about and how does this improve our understanding of both the use of the drug and what we need to be worried about?
Dr. Jason Luke: I think the toxicities of immunotherapy, while, less frequent than, say, chemotherapy, can actually be more disastrous. In the rare patients, we have extreme immune-related adverse events, there is an incidence of actually life-threatening and fatal events. And so, myocarditis, associated with checkpoint blockade, is one of those things that could be seen, and here at ASCO Annual Meeting, we saw a couple of abstracts summarizing the experience from the National Cancer Institute following myocarditis events, and then this abstract in a translational level trying to better understand what is actually going on in terms of the immune response in those myocarditis cases.
And so, I thought this was actually a very interesting abstract. There was only a small number of patients. They had 13 samples from patients who had had endomyocardial biopsies in the context of immune-related myocarditis, and you might say, well, only 13 samples, but fortunately, this is quite a rare event, less than 1% of patients who get immune checkpoint inhibitors. And what they saw was relatively unsurprising, which is that in patients who were having myocarditis, they saw an increase in T cells and in K-cells, as well as activated CD8 and CD4 T-cells.
I think what was very interesting was when they started to dig into what were the phenotypes of the cells and what were the pathways that were turned on. Again, it was not especially surprising to see that they saw increased levels of interferon signaling and immune-receptor signaling as well as motility and adhesion, but this really, I think emphasizes that there are potentially interventions beyond just the general immune-suppression approaches that we give. They could be more nuanced but perhaps more efficacious because sadly, patients do pass away when they develop this. And in their cohort of 13 patients, 3 of those patients died. And specifically, in looking in those 3 patients, they actually saw that all 3 patients had a shared T cell cluster. And they can’t exactly say what it is exactly yet, but I think it’s very interesting to see that because it suggests that there’s probably something about the T cell response in those patients that disproportionately triggered a fatal event.
And if we can understand that better, we then may be able to really tailor our interventions in a way that is more useful. Because, frankly, the way these patients usually present is they show up in the emergency room (ER), and they’re seen by an ER doctor who thinks they’re having acute coronary. They ship them off to the catheterization (cath) lab. They open him up, and then they get in there, and there’s nothing going on. There’s no plaque. And so now, all of a sudden, everyone is quite confused. And so, if we had better ways to search for that ahead of time to be aware of it, we might have better interventions because usually what happens right at that moment is everybody gets very confused and starts calling the oncologist, and we start slapping on steroids and other immunomodulatory agents, but sometimes it’s late.
So, I think this is a great abstract. It’s really starting to preliminary give us an idea of what is the actual biology that underpins these terrible events, and we can hope that we can build off that over time hopefully to eventually come up with better predictors and then obviously better interventions to try to avoid these outcomes in a small but real number of patients.
Dr. Diwakar Davar: Excellent. One other point is you and I are both involved in drug development, and as we start thinking of side effects. Side effects are really on the flip side of responses in drug development. So really 1 point to make of this is that when people start developing side effects rather than, as you say, putting your hands up in the air and waving them around, 1 of the things that we should be doing in drug development is possibly biopsying these patients because we could get new PD insights into how these drugs work, why they work, and particularly which sub-populations themselves they work on, particularly in the early-drug development setting when you oftentimes don’t have that many responses.
With that, thank you, Jason, for sharing your insights with us today.
