George Ogilvie, President and CEO of Arizona Sonoran Copper (TSX:ASCU – OTCQX:ASCUF), joins us to outline the key metrics from the Pre-Feasibility Study (PFS) on the Cactus Project in Arizona and the envisioned mine plan. We also get an exploration update, more clarity around the permitting process, discuss the recent capital raise, and review the pathway to production. PFS Highlights include: Simple open pit / SXEW operation producing approximately 103,000 tonnes (226 million lbs) of estimated average annual copper cathodes over the first 10 years of mining, which would make Cactus the third largest cathode producer in the USA Industry-leading capital intensity of $10,894 per tonne of copper cathodes produced $574 million of average annual EBITDA1 Strong economics to support the continued development of Cactus with a focus on simplicity and executability of the open pit copper cathode project, on private land in Arizona Cactus Project is well positioned over the 22-year Project Life of Mine (“LoM”) to generate value at a variety of copper prices: Conventional, Cost-effective Mining and Processing: Open-pit, Heap Leach and SXEW Operation with Oxide and Enriched Materials from Cactus and Parks/Salyer open pits over 22 years of processing Cash costs (C1) of $1.34/lb, All in Sustaining Costs (“AISC”) of $1.62/lb and All in Costs (“AIC”)1 of $2.01/lb Initial mineral reserves of 513 million tons at a grade of 0.52% Total Copper in the Proven and Probable category for 5.3 billion pounds of contained copper 65% conversion of leachable M&I mineral resources to mineral reserves, with increased grades reporting to the heap leach pads Significant benefits to the local community and economy of Arizona, including projected creation of an estimated 600+ direct jobs Future mine expansion opportunities outside of the current mineable copper reserves, including late mine life primary sulphides, Cactus East and other exploration targets Final investment decision as early as Q4 2026 with targeted first cathodes in 2029 George reviews how the incorporation of the newer MainSpring area into the larger Parks-Salyer deposit, over the last 2 years has allowed for a shift in strategy from underground mining over to an open-pit mining method. They are reviewing moving the center of the open pit more towards the high-grade portion of the Park-Salyer deposit, the infill drilling showed it expanding towards that direction, which presented better economics and a faster payback period, as outlined in the PFS. George also provides some updates on permitting for the project, and the importance of it being on private land to help expedite the process, and that they should be submitting their applications later this year for administrative acceptance by early 2026, and then approval 6 months later. This permitting process will time out well with the release of their Bankable Feasibility Study. Next we discussed the news on December 2nd, which announced that the Company closed its previously announced private placement of common shares of the Company pursuant to which the Company issued, on a “bought deal” basis, 25,746,300 Common Shares, including 3,358,200 Common Shares granted to the underwriters, at a price of $3.35 per Common Share, for aggregate gross proceeds of C$86,250,105. This gives the company the runway to execute on all coming workstreams heading into the Bankable Feasibility Study and the capital stack coming together for a construction decision late next year.

Ewan Webster, President and CEO of Thesis Gold Inc. (TSXV: TAU) (WKN: A3EP87) (OTCQX: THSGF), joins us for a comprehensive overview of the Pre-Feasibility Study (PFS) announced on December 1st, at the combined Lawyers-Ranch Project, in the Toodoggone Mining District of British Columbia. This Lawyers-Ranch project hosts a resource of 4.7 million gold equivalent ounces, with a substantial silver contribution, but the PFS economics are based solely on the Proven & Probable Reserves of 3.2 Moz AuEq. PFS highlights are summarized below: Strong Economics at US$2,900 per ounce of gold (oz Au) and US$35 per ounce of silver (oz Ag): Pre-tax: 73.5%, internal rate of return ("IRR") and $3.73 billion net present value at a 5% discount rate ("NPV5%") After-tax: IRR of 54.4% and an NPV5% of $2.37 billion At US$4,100/oz Au and US$51/oz Ag: Pre-tax: 117.4% IRR and $6.86 billion NPV5% After-tax: 87.8% IRR and $4.36 billion NPV5% Strong Early Production: Strong gold-equivalent ("AuEq")* annual production rates for the first three years averaging 266,000 ounces**, and 187,000 ounces** over the Life of Mine. Increased Tonnes Processed, Increased Throughput Rates and Extended Mine Life: Despite the removal of Inferred Resources from the mine plan, total tonnes processed rose by 18% (relative to the 2024 Preliminary Economic Assessment). Process plant throughput increased by 9% to 13,700 tonnes per day (t/d) and the mine life increased to 15-years, based solely on Measured and Indicated Resources. Mineral Reserve: Maiden Mineral Reserve statement with 76.16 million tonnes of ore grading 0.97 g/t Au and 28 g/t Ag for a total AuEq grade of 1.33 g/t. Low All-in Sustaining Costs ("AISC"): Average AISC of US$1,185 per AuEq ounce. Silver: Silver production accounts for approximately 23% of revenue. Quick Payback: The Project offers an after-tax payback period of 1.1 years at US$2,900 Au and US$35 Ag. Capex: Initial capital expenditure is estimated at $736.2 million, with a compelling after-tax NPV5%:initial capital ratio of 3.2:1. The initial capital estimate does not consider a potential revenue of $91.1 million in pre-production revenue from processing stockpiles as part of the initial commissioning and ramp-up plan. Project Upside: Significant project upside exists both in the potential to further optimize engineering design through a Feasibility Study, and in the project-wide exploration potential that remains untapped. The PFS did not include recovery of the crown pillar between the open pit and underground workings. With further study there is an opportunity to increase the mineable ore from underground without impacting the open pits. Inferred mineral resources from both Ranch and Lawyers are not captured within the PFS mine plan. Upgrading the classification of these Inferred ounces through additional drilling presents an opportunity to potentially expand the mineable materials. Numerous early-stage and undrilled targets exist across the entirety of the Lawyers-Ranch tenure, and Thesis is focused on a comprehensive, systems-based approach to unlocking additional exploration potential in an emerging porphyry district.

JCO Editor-in-Chief Dr. Jonathan Friedberg is joined by colleagues Dr. Jennifer Woyach, Dr. Wojciech Jurczak, and Dr. Matthew Davids to discuss simultaneous publications presented at ASH 2025 on pertibrutinib, a new upfront treatment option for patients with chronic lymphocytic leukemia. TRANSCRIPT The disclosures for guests on this podcast can be found in the show notes. Dr. Jonathan Friedberg: I'm Jonathan Friedberg, editor of Journal of Clinical Oncology, and welcome to JCO After Hours, where we are covering two manuscripts that were presented at the American Society of Hematology meeting 2025 in Orlando, Florida. I am delighted to be joined by colleagues on this call to discuss these pivotal manuscripts which cover the topic of pirtobrutinib, a new upfront treatment option for patients with chronic lymphocytic leukemia. I will first just introduce our guests, Dr. Woyach. Dr. Jennifer Woyach: Hi, my name is Jennifer Woyach. I am from the Ohio State University. Dr. Wojciech Jurczak: Hello, I am Wojciech Jurczak, working at the National Research Institute of Oncology in Krakow, Poland. Dr. Matthew Davids: Hi, I am Matthew Davids from Dana-Farber Cancer Institute in Boston. Dr. Jonathan Friedberg: We are going to start by just learning a little bit about these two trials that were both large, randomized phase 3 studies that I think answered some definitive questions. We will start with your study, Jennifer. If you could just describe the design of your study and the patient population. Dr. Jennifer Woyach: Absolutely. So this is the BRUIN CLL-314 study, and this is a phase 3 randomized trial of pirtobrutinib versus ibrutinib in patients with CLL or SLL who had not previously been treated with a covalent BTK inhibitor. The patients were both treatment-naive and relapsed/refractory, about one-third of the patients treatment-naive, the rest relapsed/refractory, and they were stratified based upon 17p deletion and the number of prior lines of therapy. The primary objective was looking at non-inferiority of overall response rate over the entire treated population as well as the relapsed/refractory patient population. Key secondary objectives included progression-free survival in the intention-to-treat and the smaller relapsed/refractory and treatment-naive populations. Dr. Jonathan Friedberg: And just comment a little bit on the risk of the patients. Dr. Jennifer Woyach: This study was fairly typical of this cohort of patients. Within the relapsed/refractory patient population, there was a median of one prior line of therapy in each of the groups, up to nine prior lines of therapy in the patients included on the study. For the overall cohort, about two-thirds of the patients were IGHV unmutated, about 15% had 17p deletion, 30% had TP53 mutations, and about 35% to 40% had a complex karyotype, which is three or more abnormalities. Dr. Jonathan Friedberg: And what were your findings? Dr. Jennifer Woyach: Regarding the primary outcome, which is the focus of the publication, we did find that pirtobrutinib was indeed non-inferior and actually superior to ibrutinib for overall response rate throughout the entire patient population and in both the relapsed/refractory and treatment-naive cohorts. PFS is a little bit immature at this time but is trending towards also being significantly better in pirtobrutinib-treated patients compared with ibrutinib-treated patients. Probably most significantly, we found this to be the case in the treatment-naive cohort where there was a striking trend to an advantage of pirtobrutinib versus ibrutinib. Dr. Jonathan Friedberg: And the follow-up that you have on that progression-free survival? Dr. Jennifer Woyach: So we have about 18 months follow-up on progression-free survival. Dr. Jonathan Friedberg: The second study, Wojciech, can you just go through the design and patient population that you treated? Dr. Wojciech Jurczak: Thank you, Dr. Friedberg, for this question. So the BRUIN CLL-313 study was, in fact, the first phase 3 study with pirtobrutinib in exclusively untreated CLL patients. It was a randomized study where we challenged pirtobrutinib versus bendamustine-rituximab. At the time we designed the protocol, bendamustine-rituximab was an option as a standard of care, and Bruton tyrosine kinase monotherapy was used far more commonly than nowadays. The primary target of the study was progression-free survival. We took all untreated patients except for those with 17p deletions. Therefore, it is a good representation for intermediate risk. We had about 60% of the population, 56 to be precise, which was unmutated, evenly distributed into two treatment arms. 17p deleted cases were excluded, but we had about 7% and 8% of TP53 mutated patients as well as about 11% and 7%, respectively, in the pirtobrutinib and bendamustine-rituximab arm of patients with complex karyotype. The progression-free survival was in favor of pirtobrutinib and was assessed by an independent review committee. What is important is that the progression-free survival of the bendamustine-rituximab arm was actually similar to the other studies addressing the same questions, like the comparison with ibrutinib in the ALLIANCE study or zanubrutinib in the SEQUOIA study. What was different was the hazard ratio. In our study, it was 0.20. It was one of the longest effect sizes noted in the frontline BTK study. It represented an 80% reduction in progression-free survival or death. If we compare it to ibrutinib or zanubrutinib, it was 0.39 and 0.42 respectively. Presumably, this great effect contributed towards a trend of overall survival difference. Although survival data are not mature enough, there is a clear trend represented by three patients we lost in the pirtobrutinib arm versus 10 patients lost in the bendamustine-rituximab arm. This trend in overall survival is becoming statistically significant despite the fact that there was a possibility of crossover, and effectively 52.9 patients, which means 18 out of 34 patients relapsing in the bendamustine-rituximab arm, were treated by pirtobrutinib. Dr. Jonathan Friedberg: I am going to turn it over to Matt. The question is: why study pirtobrutinib in this patient population? And then with these two studies, how do you find the patients that were treated, are they representative of people who you see? And do you see this maybe being approved and more widely available? Dr. Matthew Davids: I think in terms of the first question, why study this in a frontline population, we have seen very impressive data with pirtobrutinib in a very difficult-to-treat population of CLL patients. This was from the original BRUIN phase 1/2 study where most of the patients had at least two or three lines of therapy, often both a covalent BTK inhibitor and the BCL2 inhibitor venetoclax, and yet they were still responding to pirtobrutinib. The drug was also very well tolerated in that early phase experience. And actually, we have seen phase 3 data from the BRUIN 321 study comparing pirtobrutinib to bendamustine and rituximab in a relapse population as well. So I think that really motivated these studies to look at pirtobrutinib as a first therapy. You know, often in other cancers of course, we want to use our best therapy first, and I think these studies are an initial step at looking at that. In terms of the second question around the patient population, these are pretty representative patient populations, I would say, for most frontline CLL studies. We see patients who are a bit younger and fitter than sort of the general population of CLL patients who are treated in clinical practice, and I think that is true here as well. Median age in the sort of mid-60s here is a bit younger than the typical patients we are treating in practice. But that is not different from other CLL frontline studies that we have seen recently, so I think it makes it a little bit easier as we kind of think across studies to feel comfortable that these are relatively similar populations. Dr. Jonathan Friedberg: How do you see this either getting regulatory approval or potentially being used compared to current standard of care options? Dr. Matthew Davids: So my understanding is that both of these trials were designed with registrational intent in the frontline setting, and they are both positive studies. That is certainly very encouraging in terms of the potential for an approval here. We have seen in terms of the FDA recently some concerns around the proportion of patients who are coming from North America, and my understanding is that is relatively low on these two studies. But nonetheless, the datasets are very impressive, and so I think it is certainly supportive of regulatory approval for frontline pirtobrutinib. Dr. Jonathan Friedberg: I will ask Jennifer a question. The control arm in your study was ibrutinib, and I think many in the audience may recognize that newer, second-generation BTK inhibitors like acalabrutinib and zanubrutinib are more frequently used now if monotherapy is decided. How do you respond to that, and how would you put your results in your pirtobrutinib arm in context with what has been observed with those agents? Dr. Jennifer Woyach: Yeah, that is a great question. Even though in the United States we are predominantly using acalabrutinib or zanubrutinib when choosing a monotherapy BTK inhibitor, this is actually not the case throughout the entire world where ibrutinib is still used very frequently. The head-to-head studies of both acalabrutinib and zanubrutinib compared to ibrutinib have shown us pretty well what the safety profile and efficacy profile of the second-generation BTK inhibitors is. So even though we do not have a head-to-head study of acalabrutinib or zanubrutinib versus pirtobrutinib, I think, given the entirety of data that we have with all of the covalent BTK inhibitors, I think we can safely look at the pirtobrutinib arm here, how the ibrutinib arm compares or performs in context with those other clinical trials. And though we really can not say anything about pirtobrutinib versus acalabrutinib or zanubrutinib, I think we can still get a good idea of what might be the clinical scenarios in which you might want to choose pirtobrutinib. Dr. Jonathan Friedberg: And Wojciech, do you agree with that? Obviously, I think you have acknowledged that chemoimmunotherapy is rarely used anymore as part of upfront treatment for CLL. So, I guess a similar question. If you were to put the pirtobrutinib result in your study in context with, I guess, more contemporary type controls, would you agree that it is competitive? Dr. Wojciech Jurczak: Well, I think that that was the last study ever where bendamustine-rituximab was used as a comparator arm. So we should notice that smashing difference. Because if we look at the progression-free survival at two years, we have 93.4% in pirtobrutinib arm versus 70.7% in bendamustine-rituximab arm. Bendamustine-rituximab arm did the same as in the other trials, like ALLIANCE or SEQUOIA. Pirtobrutinib did exceptionally well, as pirto is not just the very best BTK inhibitor overcoming the resistance, but perhaps even more important for the first line, it is very well tolerated and is a very selective drug. Now, if we look at treatment-related adverse events, the discontinuation rate, they were hardly ever seen. If we compared the adverse events in exposure-adjusted incidence, literally all adverse events were two or three times higher in bendamustine-rituximab arm except for the bleeding tendency, which however was predominantly in CTCAE grade 1 and 2 with just 0.7% of grade 3 hemorrhage. Therefore, I think that we should actually put the best and the safest drugs upfront if we may, and pirtobrutinib is, or should be, the first choice if we choose monotherapy. Now, I understand that we are not presenting you the data of pirtobrutinib in combination with anti-CD20 or with BCL2 inhibitors, but that is to come. Dr. Jonathan Friedberg: Matt, how would you envision, were regulatory approval granted and this were an option, using this in the upfront patient population? Is there anybody who you would preferentially use this or start on this treatment? Or would this be something that you would tend to reserve for second line? Dr. Matthew Davids: So I would say that in general for most of my patients who would want to start with a continuous BTK inhibitor, I would still use a covalent BTK inhibitor, and I say that for a couple of reasons despite the very promising data from these studies. The first is that the follow-up for both of these phase 3 trials is still quite short, in the range of a median 18 to 24 months. And we know that CLL is a marathon, not a sprint, and these patients are going to probably be living for a very long time. And we do have much longer follow-up from the covalent BTK inhibitors, median of 10-year follow-up with ibrutinib and five to six years with zanubrutinib and acalabrutinib respectively. And you know, I do not think that the pirtobrutinib is going to fall off a cliff after two years, but on the other hand, I think there is a lot of value to long-term data in this disease, and that is why I think for most of my patients I would stick with covalent BTK inhibitors. But the other important factor that we need to consider is patients who are younger and may have many different CLL treatments over the years. We have to be very careful, I think, about how we sequence these drugs. We know right now that we can start with covalent BTK inhibitors and then subsequently patients will respond well to the non-covalent inhibitor pirtobrutinib in later lines of therapy. But right now we do not have prospective data the other way around. So how will the patients on these studies who progress on pirtobrutinib respond to covalent BTK inhibitors? We do not know yet. There have not been a lot of progression events, which is great, but we would like to see some data in that respect to feel more comfortable with that sequence. Now, I do think that particularly for older patients and those who have significant cardiovascular comorbidities, if they wanted to go on a continuous BTK inhibitor, I do think these data really strongly support using pirtobrutinib as the BTK inhibitor of choice in that population. In particular, the cardiovascular risks with pirtobrutinib seem to be quite low. I was very struck in the comparison with BR that the rate of AFib was equivalent between the two arms of the study. And that is really the first time we have seen that with any of these BTK inhibitors, no elevated risk of AFib in a randomized study. I think that is the population where it will get the most traction first, is the upfront, sort of older patient with significant cardiovascular comorbidities. And as the data from these studies mature, I think that we will start to see more widespread use of pirtobrutinib in the frontline setting. Dr. Jonathan Friedberg: Jennifer, I am just curious if you have any personal experience or heard anecdotally about after progression on pirtobrutinib the use of other BTK inhibitors and whether there is a growing experience there. Dr. Jennifer Woyach: I do not think that there is much clinical experience, you know, as Matt alluded to, it certainly has not been tested yet. There has been some data in relapsed CLL suggesting that in people who have resistance mutations to covalent BTK inhibitors after treatment with pirtobrutinib, sometimes those mutations go away. I think most of us are concerned that they are probably not actually gone but maybe in compartments that we just have not sampled, suggesting that sort of approach where you might sequence a covalent inhibitor after a non-covalent in somebody who had already been resistant probably would not work that well. But, you know, in this setting where people had never been exposed to a covalent BTK inhibitor before, we really have no idea what the resistance patterns are going to be like. We assume they will be the same as what we have seen in relapsed CLL, but I think we just need some longer follow-up to know for sure. Dr. Wojciech Jurczak: If I may confront Dr. Davids about the use of covalent BTK inhibitors upfront, well, I think that we should abandon the idea of using the first and the second and the third generation, at least if we don't have medical lines. If we endlessly block the same pathway, it is not going to be effective. So if pirtobrutinib gets approval in first, second line, we do not necessarily have to use it in the first line. I am not here in a position to defend that we should treat patients with pirtobrutinib upfront and not BCL2 time-limited regimen. However, the way I look at CLL patients when choosing therapy is not just how should I treat them now, but what would be the best regimen in 5, 10 years if I have to re-treat them. And in some instances, the idea may be that in this setting we would like to have a BTK inhibitor upfront to have a BCL2 inhibitor later to make it time-limited. Although I understand and I agree with Matthew that if we have an elderly, fragile population, then the charm of having a drug taken once a day in a tablet with literally few cardiovascular adverse events might be an option. Dr. Jonathan Friedberg: And I will give Matt the last word whether he wants to respond to that, and also just as a forward-looking issue, I know both investigators have implied that there will be future studies looking at combinations with pirtobrutinib, and if you have any sense as to what you would be looking for there. Dr. Matthew Davids: The field really is heading toward time-limited therapy for most patients, I would say. There is a bit of a discrepancy right now in the field between sort of what we are doing in academic practice and what is done sort of more widely in community practice. And so right now we are going to see evolving datasets comparing these approaches. We are already seeing data now from the CLL17 study with ibrutinib comparing continuous to time-limited venetoclax-based therapy, and we are seeing similar efficacy benefits from these time-limited therapies without the need for continuous treatment. And so that is where I think some of the future studies with pirtobrutinib combining it with venetoclax and other partners are so important. Fortunately, several of these studies are already ongoing, including a phase 3 trial called CLL18, which is looking at pirtobrutinib with venetoclax, comparing that to venetoclax and obinutuzumab. So I am optimistic that we are going to be developing these very robust datasets where we can actually use pirtobrutinib in the frontline setting as a time-limited therapy as a component of a multi-drug regimen. So far, those early data are very promising. Dr. Wojciech Jurczak: Perhaps last but not least, in a single center we have treated over 300 patients with pirtobrutinib. So eventually some of them relapsed. And I must say that our experience on BCL2 inhibitors, not just venetoclax but including sonrotoclax, are appealingly good. Therefore, by using pirtobrutinib even earlier, we do not block the efficacy of other compounds. Dr. Jonathan Friedberg: All right. Well, I want to thank all of our speakers. I also want to congratulate our two guests who presented these very influential papers at the ASH Annual Meeting, and chose to publish them in JCO, so we thank you for that, and Dr. Davids for your commentary - really appreciated.

In this episode of JCO Article Insights, host Dr. Ece Cali Daylan interviews author Dr. Jeffrey Bradley about the article, "Simultaneous Durvalumab and Chemoradiotherapy in Unresectable Stage III Non–Small Cell Lung Cancer" by Bradley, et al published October 13, 2025. TRANSCRIPT Dr. Ece Cali: Welcome to this episode of JCO Article Insights. This is Dr. Ece Cali, JCO Editorial Fellow. Today I'm joined by Dr. Jeffrey Bradley, Professor of Radiation Oncology at the University of Pennsylvania, to discuss the manuscript, "Simultaneous Durvalumab and Platinum-Based Chemoradiotherapy in Unresectable Stage III Non-Small-Cell Lung Cancer: The Phase III PACIFIC-2 Study." The PACIFIC-2 study was a phase III, double-blind, randomized trial comparing the efficacy and safety of simultaneous durvalumab with concurrent chemoradiation followed by consolidation durvalumab to the concurrent chemoradiation followed by placebo in patients with unresectable stage III non-small cell lung cancer. The primary endpoint was progression-free survival by blinded independent central review. The secondary endpoints were overall response rate, overall survival, and safety. Three hundred twenty-eight patients were randomized 2:1 to durvalumab and placebo, respectively. Unfortunately, this trial did not meet its primary endpoint. There were no statistically significant differences in PFS or OS. The frequency of adverse events was similar between the two arms. Grade 3 or higher adverse events were observed in 53% of the patients in the durvalumab arm compared to 59% of the patients in the placebo arm. Of note, the frequency of pneumonitis was similar in the two arms. Approximately 28% of patients in each arm developed pneumonitis, and about 5% of the pneumonitis observed in each arm was grade 3 or higher in severity. Treatment discontinuation rates secondary to the adverse events were higher in the durvalumab arm, 25% compared to 12%. Adverse events leading to treatment discontinuation and death were more frequently seen in the durvalumab arm during the first four months of the treatment, which corresponds to the simultaneous administration of chemoradiation and durvalumab. Dr. Bradley, before we delve into the results, can you please explain the rationale for this study design and how this concept fits into the current treatment landscape? Dr. Jeffrey Bradley: Yeah, this trial came on the heels of PACIFIC after there was a progression-free survival benefit showed in PACIFIC that in the locally advanced unresectable population that consolidation immunotherapy, in this case durvalumab, had a progression-free survival benefit. A number of us in the clinical trial space thought to add concurrent immunotherapy in addition to consolidation immunotherapy that that would also improve outcomes for patients. So a number of trials were launched to follow up of PACIFIC. In this case, this is a phase III trial where the control arm was placebo. There was no overall survival results yet from PACIFIC, just a PFS benefit, and a number of countries across the world had not approved maintenance durvalumab in this space. So this trial looked at the experimental arm, which was concurrent immunotherapy, durvalumab, and chemoradiation followed by consolidation durvalumab versus placebo. Dr. Ece Cali: And if we were to focus on the safety profile first, an increased pneumonitis risk was a theoretical concern when immunotherapy is given concurrently with radiation. Do we see any major differences in the safety profile between the two arms in this trial? Dr. Jeffrey Bradley: No, and we were concerned about the addition of concurrent immunotherapy and chemoradiation, like you said, towards concern about increased pneumonitis rate, but we did not see increased pneumonitis in the experimental arm over placebo. And the grade 3 or higher, as you said, it was roughly 5%, more or less, in both arms, so we didn't see increase in pneumonitis toxicity with concurrent IO and chemoradiation. Dr. Ece Cali: But interestingly though, despite the lack of significantly increased toxicity with durvalumab, unfortunately, administering immunotherapy simultaneously with chemoradiation therapy did not improve survival. Lack of superiority of this treatment regimen, as you mentioned, is further confirmed across multiple similar negative trial readouts such as ECOG-ACRIN 5181 and CheckMate 73L. Dr. Bradley, in your view, what are some potential explanations for why this strategy did not pan out in clinical trials? Dr. Jeffrey Bradley: Regarding toxicity, let me go back and point out that we did see an increased number of immune-mediated adverse events. It was 34.7% in the concurrent immunotherapy arm versus 15.7% in the placebo arm. So that led to a higher number of discontinuations of immunotherapy which I think probably had an effect. So we didn't... there was an increased pneumonitis toxicity, but there were expected immune-mediated toxicities that caused people to stop giving immunotherapy. You can see that in the PFS curves. They were, you know, they crossed over after like a month, but initially there was lower PFS for the experimental arm, and then the experimental arm got better after we divided into four months, before four months and after four months. Dr. Ece Cali: For one reason or another, it looks like the simultaneous administration did not really improve outcomes. We now know that simultaneously giving them another concurrent radiation should really no longer be pursued in clinical trials for this patient population. Can you share with our audience what strategies are being studied in this setting and what trials to watch out for in the future? Dr. Jeffrey Bradley: Sure, I think when you add concurrent radiation to immunotherapy, there were more central tumors in this trial, I think you're killing lymphocytes and negating the effect of immunotherapy. So I think that's the smoking gun for this trial, for the ECOG trial, for the small cell trial that NRG reported, LU005, and other trials. So correct, I don't think there's any need to continue to pursue concurrent immunotherapy in this space of lung cancer. But that's not to say there aren't many other trials that are either ongoing, have accrued and awaiting results, or being planned for the next phase of clinical trials. We have a trial within NRG Oncology called NRG-LU008. It's a randomized phase III trial that is using an SBRT boost to a peripheral primary and chemoradiation to the nodes, because the primary tumor is the one that fails more often than the lymph nodes, and that's compared to PACIFIC in the control arm. PACIFIC-9 is another trial in the same line as the other PACIFIC trials. That one is using dual checkpoint inhibition versus the control arm being PACIFIC. So there are three arms in that trial, durva and oleclumab, durva and monalizumab versus the PACIFIC arm. And that trial is completed accrual, but we have no results from that study yet. Johnson & Johnson has a trial open looking at a nanoparticle. That's a radiosensitizer where bronchoscopy is used to inject the primary tumor and the lymph nodes with a radiosensitizer. That's a randomized phase ll trial that's ongoing. It's got three arms, two different doses of this radiosensitizing drug and then a control arm without injection at all. The control arm is again the PACIFIC arm. And then those of us within the NCI-based clinical trials evaluation program, CTEP, are proposing an intergroup trial that would compare induction chemo-immunotherapy followed by chemoradiation followed by maintenance immunotherapy versus PACIFIC in a phase III study. So I think there's other trials that are either completed, ongoing completed, or on the horizon to assess in this patient population. Dr. Ece Cali: Yeah, we definitely have an unmet need to improve survival outcomes for stage III patients, and it's great to hear that there are so many efforts looking at different strategies to improve outcomes for these patients. Thank you so much, Dr. Bradley, for this informative discussion and for sharing your insights. Any last thoughts? Dr. Jeffrey Bradley: Yeah, we need something, you know. PACIFIC was first reported in 2017, and we really haven't made progress in terms of changing that standard of care control for the last eight years. So we need progress in this area. Dr. Ece Cali: Yep, definitely. Thank you so much for joining, Dr. Bradley. And thank you for listening to JCO Article Insights.

Dr. Linda Duska and Dr. Kathleen Moore discuss key studies in the evolving controversy over radical upfront surgery versus neoadjuvant chemotherapy in advanced ovarian cancer. TRANSCRIPT Dr. Linda Duska: Hello, and welcome to the ASCO Daily News Podcast. I am your guest host, Dr. Linda Duska. I am a professor of obstetrics and gynecology at the University of Virginia School of Medicine. On today's episode, we will explore the management of advanced ovarian cancer, specifically with respect to a question that has really stirred some controversy over time, going all the way back more than 20 years: Should we be doing radical upfront surgery in advanced ovarian cancer, or should we be doing neoadjuvant chemotherapy? So, there was a lot of hype about the TRUST study, also called ENGOT ov33/AGO-OVAR OP7, a Phase 3 randomized study that compares upfront surgery with neoadjuvant chemotherapy followed by interval surgery. So, I want to talk about that study today. And joining me for the discussion is Dr. Kathleen Moore, a professor also of obstetrics and gynecology at the University of Oklahoma and the deputy director of the Stephenson Cancer Center, also at the University of Oklahoma Health Sciences. Dr. Moore, it is so great to be speaking with you today. Thanks for doing this. Dr. Kathleen Moore: Yeah, it's fun to be here. This is going to be fun. Dr. Linda Duska: FYI for our listeners, both of our full disclosures are available in the transcript of this episode. So let's just jump right in. We already alluded to the fact that the TRUST study addresses a question we have been grappling with in our field. Here's the thing, we have four prior randomized trials on this exact same topic. So, share with me why we needed another one and what maybe was different about this one? Dr. Kathleen Moore: That is, I think, the key question. So we have to level-set kind of our history. Let's start with, why is this even a question? Like, why are we even talking about this today? When we are taking care of a patient with newly diagnosed ovarian cancer, the aim of surgery in advanced ovarian cancer ideally is to prolong a patient's likelihood of disease-free survival, or if you want to use the term "remission," you can use the term "remission." And I think we can all agree that our objective is to improve overall survival in a way that also does not compromise her quality of life through surgical complications, which can have a big effect. The standard for many decades, certainly my entire career, which is now over 20 years, has been to pursue what we call primary cytoreductive surgery, meaning you get a diagnosis and we go right to the operating room with a goal of achieving what we call "no gross residual." That is very different – in the olden days, you would say "optimal" and get down to some predefined small amount of tumor. Now, the goal is you remove everything you can see. The alternative strategy to that is neoadjuvant chemotherapy followed by interval cytoreductive surgery, and that has been the, quote-unquote, "safer" route because you chemically cytoreduce the cancer, and so, the resulting surgery, I will tell you, is not necessarily easy at all. It can still be very radical surgeries, but they tend to be less radical, less need for bowel resections, splenectomy, radical procedures, and in a short-term look, would be considered safer from a postoperative consideration. Dr. Linda Duska: Well, and also maybe more likely to be successful, right? Because there's less disease, maybe, theoretically. Dr. Kathleen Moore: More likely to be successful in getting to no gross residual. Dr. Linda Duska: Right. Yeah, exactly. Dr. Kathleen Moore: I agree with that. And so, so if the end game, regardless of timing, is you get to no gross residual and you help a patient and there's no difference in overall survival, then it's a no-brainer. We would not be having this conversation. But there remains a question around, while it may be more likely to get to no gross residual, it may be, and I think we can all agree, a less radical, safer surgery, do you lose survival in the long term by this approach? This has become an increasing concern because of the increase in rates of use of neoadjuvant, not only in this country, but abroad. And so, you mentioned the four prior studies. We will not be able to go through them completely. Dr. Linda Duska: Let's talk about the two modern ones, the two from 2020 because neither one of them showed a difference in overall survival, which I think we can agree is, at the end of the day, yes, PFS would be great, but OS is what we're looking for. Dr. Kathleen Moore: OS is definitely what we're looking for. I do think a marked improvement in PFS, like a real prolongation in disease-free survival, for me would be also enough. A modest improvement does not really cut it, but if you are really, really prolonging PFS, you should see that- Dr. Linda Duska: -manifest in OS. Dr. Kathleen Moore: Yeah, yeah. Okay. So let's talk about the two modern ones. The older ones are EORTC and CHORUS, which I think we've talked about. The two more modern ones are SCORPION and JCOG0602. So, SCORPION was interesting. SCORPION was a very small study, though. So one could say it's underpowered. 170 patients. And they looked at only patients that were incredibly high risk. So, they had to have a Fagotti score, I believe, of over 9, but they were not looking at just low volume disease. Like, those patients were not enrolled in SCORPION. It was patients where you really were questioning, "Should I go to the OR or should I do neoadjuvant? Like, what's the better thing?" It is easy when it's low volume. You're like, "We're going." These were the patients who were like, "Hm, you know, what should I do?" High volume. Patients were young, about 55. The criticism of the older studies, there are many criticisms, but one of them is that, the criticism that is lobbied is that they did not really try. Whatever surgery you got, they did not really try with median operative times of 180 minutes for primary cytoreduction, 120 for neoadjuvant. Like, you and I both know, if you're in a big primary debulking, you're there all day. It's 6 hours. Dr. Linda Duska: Right, and there was no quality control for those studies, either. Dr. Kathleen Moore: No quality control. So, SCORPION, they went 451-minute median for surgery. Like, they really went for it versus four hours and then 253 for the interval, 4 hours. They really went for it on both arms. Complete gross resection was achieved in 50% of the primary cytoreduced. So even though they went for it with these very long surgeries, they only got to the goal half the time. It was almost 80% in the interval group. So they were more successful there. And there was absolutely no difference in PFS or OS. They were right about 15 months PFS, right about 40 months OS. JCOG0602, of course, done in Japan, a big study, 300 patients, a little bit older population. Surprisingly more stage IV disease in this study than were in SCORPION. SCORPION did not have a lot of stage IV, despite being very bulky tumors. So a third of patients were stage IV. They also had relatively shorter operative times, I would say, 240 minutes for primary, 302 for interval. So still kind of short. Complete gross resection was not achieved very often. 30% of primary cytoreduction. That is not acceptable. Dr. Linda Duska: Well, so let's talk about TRUST. What was different about TRUST? Why was this an important study for us to see? Dr. Kathleen Moore: So the criticism of all of these, and I am not trying to throw shade at anyone, but the criticism of all of these is if you are putting surgery to the test, you are putting the surgeon to the test. And you are assuming that all surgeons are trained equally and are willing to do what it takes to get someone to no gross residual. Dr. Linda Duska: And are in a center that can support the post-op care for those patients. Dr. Kathleen Moore: Which can be ICU care, prolonged time. Absolutely. So when you just open these broadly, you're assuming everyone has the surgical skills and is comfortable doing that and has backup. Everybody has an ICU. Everyone has a blood bank, and you are willing to do that. And that assumption could be wrong. And so what TRUST said is, "Okay, we are only going to open this at centers that have shown they can achieve a certain level of primary cytoreduction to no gross residual disease." And so there was quality criteria. It was based on – it was mostly a European study – so ESGO criteria were used to only allow certified centers to participate. They had to have a surgical volume of over 36 cytoreductive surgeries per year. So you could not be a low volume surgeon. Your complete resection rates that were reported had to be greater than 50% in the upfront setting. I told you on the JCOG, it was 30%. Dr. Linda Duska: Right. So these were the best of the best. This was the best possible surgical situation you could put these patients in, right? Dr. Kathleen Moore: Absolutely. And you support all the things so you could mitigate postoperative complications as well. Dr. Linda Duska: So we are asking the question now again in the ideal situation, right? Dr. Kathleen Moore: Right. Dr. Linda Duska: Which, we can talk about, may or may not be generalizable to real life, but that's a separate issue because we certainly don't have those conditions everywhere where people get cared for with ovarian cancer. But how would you interpret the results of this study? Did it show us anything different? Dr. Kathleen Moore: I am going to say how we should interpret it and then what I am thinking about. It is a negative study. It was designed to show improvement in overall survival in these ideal settings in patients with FIGO stage IIIB and C, they excluded A, these low volume tumors that should absolutely be getting surgery. So FIGO stage IIIB and C and IVA and B that were fit enough to undergo radical surgery randomized to primary cytoreduction or neoadjuvant with interval, and were all given the correct chemo. Dr. Linda Duska: And they were allowed bevacizumab and PARP, also. They could have bevacizumab and PARP. Dr. Kathleen Moore: They were allowed bevacizumab and PARP. Not many of them got PARP, but it was distributed equally, so that would not be a confounder. And so that was important. Overall survival is the endpoint. It was a big study. You know, it was almost 600 patients. So appropriately powered. So let's look at what they reported. When they looked at the patients who were enrolled, this is a large study, almost 600 patients, 345 in the primary cytoreductive arm and 343 in the neoadjuvant arm. Complete resection in these patients was 70% in the primary cytoreductive arm and 85% in the neoadjuvant arm. So in both arms, it was very high. So your selection of site and surgeon worked. You got people to their optimal outcome. So that is very different than any other study that has been reported to date. But what we saw when we looked at overall survival was no statistical difference. The median was, and I know we do not like to talk about medians, but the median in the primary cytoreductive arm was 54 months versus 48 months in the neoadjuvant arm with a hazard ratio of 0.89 and, of course, the confidence interval crossed one. So this is not statistically significant. And that was the primary endpoint. Dr. Linda Duska: I know you are getting to this. They did look at PFS, and that was statistically significant, but to your point about what are we looking for for a reasonable PFS difference? It was about two months difference. When I think about this study, and I know you are coming to this, what I thought was most interesting about this trial, besides the fact that the OS, the primary endpoint was negative, was the subgroup analyses that they did. And, of course, these are hypothesis-generating only. But if you look at, for example, specifically only the stage III group, that group did seem to potentially, again, hypothesis generating, but they did seem to benefit from upfront surgery. And then one other thing that I want to touch on before we run out of time is, do we think it matters if the patient is BRCA germline positive? Do we think it matters if there is something in particular about that patient from a biomarker standpoint that is different? I am hopeful that more data will be coming out of this study that will help inform this. Of course, unpowered, hypothesis-generating only, but it's just really interesting. What do you think of their subset analysis? Dr. Kathleen Moore: Yeah, I think the subsets are what we are going to be talking about, but we have to emphasize that this was a negative trial as designed. Dr. Linda Duska: Absolutely. Yes. Dr. Kathleen Moore: So we cannot be apologists and be like, "But this or that." It was a negative trial as designed. Now, I am a human and a clinician, and I want what is best for my patients. So I am going to, like, go down the path of subset analyses. So if you look at the stage III tumors that got complete cytoreduction, which was 70% of the cases, your PFS was almost 28 months versus 21.8 months. Dr. Linda Duska: Yes, it becomes more significant. Dr. Kathleen Moore: Yeah, that hazard ratio is 0.69. Again, it is a subset. So even though the P value here is statistically significant, it actually should not have a P value because it is an exploratory analysis. So we have to be very careful. But the hazard ratio is 0.69. So the hypothesis is in this setting, if you're stage III and you go for it and you get someone to no gross residual versus an interval cytoreduction, you could potentially have a 31% reduction in the rate of progression for that patient who got primary cytoreduction. And you see a similar trend in the stage III patients, if you look at overall survival, although the post-progression survival is so long, it's a little bit narrow of a margin. But I do think there are some nuggets here that, one of our colleagues who is really one of the experts in surgical studies, Dr. Mario Leitao, posted this on X, and I think it really resonated after this because we were all saying, "But what about the subsets?" He is like, "It's a negative study." But at the end of the day, you are going to sit with your patient. The patient should be seen by a GYN oncologist or surgical oncologist with specialty in cytoreduction and a medical oncologist, you know, if that person does not give chemo, and the decision should be made about what to do for that individual patient in that setting. Dr. Linda Duska: Agreed. And along those lines, if you look carefully at their data, the patients who had an upfront cytoreduction had almost twice the risk of having a stoma than the patients who had an interval cytoreduction. And they also had a higher risk of needing to have a bowel resection. The numbers were small, but still, when you look at the surgical complications, as you've already said, they're higher in the upfront group than they are in the interval group. That needs to be taken into account as well when counseling a patient, right? When you have a patient in front of you who says to you, "Dr. Moore, you can take out whatever you want, but whatever you do, don't make me a bag." As long as the patient understands what that means and what they're asking us to do, I think that we need to think about that. Dr. Kathleen Moore: I think that is a great point. And I have definitely seen in our practice, patients who say, "I absolutely would not want an ostomy. It's a nonstarter for me." And we do make different decisions. And you have to just say, "That's the decision we've made," and you kind of move on, and you can't look back and say, "Well, I wish I would have, could have, should have done something else." That is what the patient wants. Ultimately, that patient, her family, autonomous beings, they need to be fully counseled, and you need to counsel that patient as to the site that you are in, her volume of disease, and what you think you can achieve. In my opinion, a patient with stage III cancer who you have the site and the capabilities to get to no gross residual should go to the OR first. That is what I believe. I do not anymore think that for stage IV. I think that this is pretty convincing to me that that is probably a harmful thing. However, I want you to react to this. I think I am going to be a little unpopular in saying this, but for me, one of the biggest take-homes from TRUST was that whether or not, and we can talk about the subsets and the stage III looked better, and I think it did, but both groups did really well. Like, really well. And these were patients with large volume disease. This was not cherry-picked small volume stage IIIs that you could have done an optimal just by doing a hysterectomy. You know, these were patients that needed radical surgery. And both did well. And so what it speaks to me is that anytime you are going to operate on someone with ovary, whether it be frontline, whether it be a primary or interval, you need a high-volume surgeon. That is what I think this means to me. Like, I would want high volume surgeon at a center that could do these surgeries, getting that patient, my family member, me, to no gross residual. That is important. And you and I are both in training centers. I think we ought to take a really strong look at, are we preparing people to do the surgeries that are necessary to get someone to no gross residual 70% and 85% of the time? Dr. Linda Duska: We are going to run out of time, but I want to address that and ask you a provocative question. So, I completely agree with what you said, that surgery is important. But I also think one of the reasons these patients in this study did so well is because all of the incredible new therapies that we have for patients. Because OS is not just about surgery. It is about surgery, but it is also about all of the amazing new therapies we have that you and others have helped us to get through clinical research. And so, how much of that do you think, like, for example, if you look at the PFS and OS rates from CHORUS and EORTC, I get it that they're, that they're not the same. It's different patients, different populations, can't do cross-trial comparisons. But the OS, as you said, in this study was 54 months and 48 months, which is, compared to 2010, we're doing much, much better. It is not just the surgery, it is also all the amazing treatment options we have for these patients, including PARP, including MIRV, including lots of other new therapies. How do you fit that into thinking about all of this? Dr. Kathleen Moore: I do think we are seeing, and we know this just from epidemiologic data that the prevalence of ovarian cancer in many of the countries where the study was done is increasing, despite a decrease in incidence. And why is that? Because people are living longer. Dr. Linda Duska: People are living longer, yeah. Dr. Kathleen Moore: Which is phenomenal. That is what we want. And we do have, I think, better supportive care now. PARP inhibitors in the frontline, which not many of these patients had. Now some of them, this is mainly in Europe, will have gotten them in the first maintenance setting, and I do think that impacts outcome. We do not have that data yet, you know, to kind of see what, I would be really interested to see. We do not do this well because in ovarian cancer, post-progression survival can be so long, we do not do well of tracking what people get when they come off a clinical trial to see how that could impact – you know, how many of them got another surgery? How many of them got a PARP? I think this group probably missed the ADC wave for the most part, because this, mirvetuximab is just very recently available in Europe. Dr. Linda Duska: Unless they were on trial. Dr. Kathleen Moore: Unless they were on trial. But I mean, I think we will have to see. 600 patients, I would bet a lot of them missed the ADC wave. So, I do not know that we can say we know what drove these phenomenal – these are some of the best curves we've seen outside of BRCA. And then coming back to your point about the BRCA population here, that is a really critical question that I do not know that we're ever going to answer. There have been hypotheses around a tumor that is driven by BRCA, if you surgically cytoreduced it, and then chemically cytoreduced it with chemo, and so you're starting PARP with nothing visible and likely still homogeneous clones. Is that the group we cured? And then if you give chemo first before surgery, it allows more rapid development of heterogeneity and more clonal evolution that those are patients who are less likely to be cured, even if they do get cytoreduced to nothing at interval with use of PARP inhibitor in the front line. That is a question that many have brought up as something we would like to understand better. Like, if you are BRCA, should you always just go for it or not? I do not know that we're ever going to really get to that. We are trying to look at some of the other studies and just see if you got neoadjuvant and you had BRCA, was anyone cured? I think that is a question on SOLO1 I would like to know the answer to, and I don't yet, that may help us get to that. But that's sort of something we do think about. You should have a fair number of them in TRUST. It wasn't a stratification factor, as I remember. Dr. Linda Duska: No, it wasn't. They stratified by center, age, and ECOG status Dr. Kathleen Moore: So you would hope with randomization that you would have an equal number in each arm. And they may be able to pull that out and do a very exploratory look. But I would be interested to see just completely hypothesis-generating what this looks like for the patients with BRCA, and I hope that they will present that. I know they're busy at work. They have translational work. They have a lot pending with TRUST. It's an incredibly rich resource that I think is going to teach us a lot, and I am excited to see what they do next. Dr. Linda Duska: So, outside of TRUST, we are out of time. I just want to give you a moment if there were any other messages that you want to share with our listeners before we wrap up. Dr. Kathleen Moore: It's an exciting time to be in GYN oncology. For so long, it was just chemo, and then the PARP inhibitors nudged us along quite a bit. We did move more patients, I believe, to the cure fraction. When we ultimately see OS, I think we'll be able to say that definitively, and that is exciting. But, you know, that is the minority of our patients. And while HRD positive benefits tremendously from PARP, I am not as sure we've moved as many to the cure fraction. Time will tell. But 50% of our patients have these tumors that are less HRD. They have a worse prognosis. I think we can say that and recur more quickly. And so the advent of these antibody-drug conjugates, and we could name 20 of them in development in GYN right now, targeting tumor-associated antigens because we're not really driven by mutations other than BRCA. We do not have a lot of things to come after. We're not lung cancer. We are not breast cancer. But we do have a lot of proteins on the surface of our cancers, and we are finally able to leverage that with some very active regimens. And we're in the early phases, I would say, of really understanding how best to use those, how best to position them, and which one to select for whom in a setting where there is going to be obvious overlap of the targets. So we're going to be really working this problem. It is a good problem. A lot of drugs that work pretty well. How do you individualize for a patient, the patient in front of you with three different markers? How do you optimize it? Where do you put them to really prolong survival? And then we finally have cell surface. We saw at ASCO, CDK2 come into play here for the first time, we've got a cell cycle inhibitor. We've been working on WEE1 and ATR for a long time. CDK2s may hit. Response rates were respectable in a resistant population that was cyclin E overexpressing. We've been working on that biomarker for a long time with a toxicity profile that was surprisingly clean, which I like to see for our patients. So that is a different platform. I think we have got bispecifics on the rise. So there is a pipeline of things behind the ADCs, which is important because we need more than one thing, that makes me feel like in the future, I am probably not going to be using doxil ever for platinum-resistant disease. So, I am going to be excited to retire some of those things. We will say, "Remember when we used to use doxil for platinum-resistant disease?" Dr. Linda Duska: I will be retired by then, but thanks for that thought. Dr. Kathleen Moore: I will remind you. Dr. Linda Duska: You are right. It is such an incredibly exciting time to be taking care of ovarian cancer patients with all the opportunities.
