Please be advised that today's conference is being recorded. If you require any further assistance, please press star zero. I would now like to hand the conference over to your speaker today, Julie Miller. Please go ahead. Good morning, and welcome to Adaptimmune's Conference Call to Discuss our Third Quarter 2021 Financial Results and Business Updates. Please review our forward-looking statements from this morning's press release as we anticipate making projections during this call, and actual results could differ materially due to several factors, including those outlined in our latest filings with the SEC. Adrian Rawcliffe, our Chief Executive Officer, is with me for the prepared portion of this call. Other members of our Management Team will be available for Q&A. With that, I'll turn the call over to Adrian Rawcliffe. Thanks, Julie. Thank you everyone for joining us. About this time last year, we laid out our 2-2-5-2 strategy. We are now one year into that five-year strategy, and we've made substantial progress against each of the four pillars we set out then. The first pillar was that we wanted to have two marketed products targeting MAGE-A4. The second pillar was to identify further indications with two additional BLAs for our SPEAR T-cell products. The first product we're targeting for approval is our first-generation TCR T-cell therapy targeting MAGE-A4, afami-cel. In June, we presented initial data from the SPEARHEAD-1 trial at ASCO, demonstrating that afami-cel is a life-changing therapy for people with synovial sarcoma and MRCLS. We remain on track to file our first BLA next year for afami-cel, which we anticipate will be the first engineered T-cell therapy on the market for a solid tumor indication. Based on the data presented recently at ESMO from the SURPASS trial, we have shown that our next-generation MAGE-A4-targeted therapy, ADP-A2M4CD8, is effective, with responses in five different solid tumors, an overall response rate of 36%, and an 86% disease control rate. These data confirm the potential of a broader MAGE-A4 therapy franchise. In Q3, we announced that we initiated the phase II SURPASS-2 trial for people with esophageal and EGJ cancers. Today, we announced that we will start a second phase II trial next year called SURPASS-3 for patients with ovarian cancer. We continue to enroll patients in the original phase I SURPASS trial with a focus on rapidly identifying additional indications for late-stage development. Onto our third pillar, new new autologous products in the clinic from our extensive preclinical pipeline by 2025. We've reported substantial progress with additional HLAs, new targets, and next-gen programs, with our most advanced preclinical therapies being the next-generation engineered IL-7 TIL therapy, too, in collaboration with CCIT-DK, and our next-gen MAGE-A4-targeted therapy incorporating IL-7 and CCL19 developed in collaboration with Noile-Immune. Additionally, the translational data we'll present at CTOS and SITC next week show the stellar quality of our translational science teams and how learnings from this research will help us develop better products to take into the clinic. Last but not least is our fourth pillar, two allogeneic products in the clinic by 2025. In this morning's press release, we confirmed that we plan to file our first IND in 2023 for our wholly owned allogeneic product targeting MAGE-A4. In Q3, we signed a fantastic strategic collaboration with Genentech that has now become effective and for which we will receive the upfront payment of $150 million in Q4. We also announced that we would open a dedicated allogeneic manufacturing facility next year. I believe that our Allo platform represents a significant piece of the future of cell therapy for us and our partners, and this progress confirms we are amongst the leaders in the allogeneic T-cell space. Looking forward, we'll continue to deliver updates from our trials from a clinical and a translational perspective. Following the initial data presented at ASCO for our pivotal SPEARHEAD-1 trial, next week we will present a fuller data set at CTOS in an oral presentation delivered by Dr. Brian Van Tine from Washington University. We will also present a poster highlighting translational scientific insights from this trial. At SITC next week, we'll present data demonstrating the positive impact of adding an Akt inhibitor to the expansion phase of our manufacturing process. It's a feature of developing cell therapies that epigenetic modifications during manufacturing have the potential to be as important as the genetic modifications we make to the cells themselves. In this same poster, we will present clinical translational learnings from patients in the SURPASS trial for whom we reported clinical data at ESMO, indicating that these manufacturing improvements, along with the next gen enhancements, make an improved and more potent SPEAR T-cell product for people with cancer. These types of translational learnings are critical as we aim to bring forward further next-gen products and enhancements to better address solid tumors with our cell therapy. When looking across the pipeline of ongoing clinical trials with our 2-2-5-2 goals in mind, we need to pursue our ambitions rapidly and efficiently, and critically evaluate what is and is not a product. Today, we announced that we've ceased enrollment in our SPEARHEAD-2 trial with afami-cel in combination with pembrolizumab. Given compelling activity seen with our next-gen ADP-A2M4CD8 product across a range of solid tumors, next year we'll evaluate the combination of a checkpoint inhibitor with this therapy. We will not go into details today, but we'll update in due course about the best design and the path forward. We also announced that we have enrolled a sufficient number of patients in our phase I trial with ADP-A2AFP for people with liver cancer, leading us to close screening. We presented data at ILCA demonstrating that ADP-A2AFP is an active product, with several patients receiving clinical benefits, including a durable, complete response and other patients with prolonged stable disease associated with a significant decrease in serum AFP. The response rate- to- date is not what we had hoped for. We'll analyze data from the full patient population in this trial and determine next steps, including evaluation of alternative TCRs, manufacturing improvements, and potential next gen enhancements. So far in 2021, we've delivered clear progress against our 2-2-5-2 strategy, and we will continue to deliver over the next four years. We're on track to file our first BLA. We're showing compelling data from SURPASS confirming the potential of the MAGE-A4-targeted franchise, and we're working quickly to pursue further late-stage trials, starting with the recently initiated SURPASS-2 trial in esophageal and EGJ cancers and SURPASS-3 in ovarian cancer, which we'll initiate in 2022. We're also planning to explore the use of checkpoint inhibitors alongside our next-gen product with the aim of identifying further treatment regimens for our cell therapies for people with cancer. Beyond our current clinical trials, we've continued to make progress with our autologous and allogeneic preclinical pipeline, including in collaboration with GSK, Astellas, and most recently, Genentech. All of our progress this year brings us closer to achieving our vision of being a fully integrated cell therapy company. You can really see this when you consider that we are filing a BLA and preparing for our first commercial product while simultaneously building an allogeneic manufacturing facility for future generations of cell therapies for people with cancer. As we close out the year, I'm pleased with our progress, and we'll provide further guidance for 2022 at the beginning of next year. With that, I'll turn it over for questions. Operator? As a reminder, if you would like to ask a question, please press star then one on your telephone keypad. Again, that is star then one. Your first question comes from Mark Frahm with Cowen and Company. Yes, thanks for taking my questions. Maybe on the filing, what, you know, other than obviously the presentation in about a week at CTOS, what's kind of gating to the filing going in? Is it just a little bit more follow-up on a few of the last few patients? Or are there still real discussions to be had on things like potency assays and exactly what needs to be included on it from that front? Elliot, do you want to take that? Yeah, sure. Hi Mark, and thank you. Just with respect to the BLA filing, clearly the data is not in its final format and needs to be presented in the appropriate way. The cohort that will support the filing, Cohort 1 from the SPEARHEAD-1 trial, has completed. So all the patients are enrolled and data collected and we'll be finalizing that data set in the fairly near future. While there's still work to be done, I don't think that's necessarily gating per se. There is also still work to be done with respect to demonstrating that our manufacturing and release testing are acceptable to the agencies. You know, that goes side by side with, you know, meeting the primary endpoint for efficacy and showing an acceptable safety profile. While I don't think that there are, you know, issues that are insurmountable in either of those, in any of those, there's still work to be done. That work will take us out into 2022, and we're on track to meet the timeline to file the BLA next year. Great. Thanks. That's very helpful. Maybe I realize, you know, you're just opening SURPASS-2 and SURPASS-3 hasn't fully opened yet. Given the increased demand for your trials you've seen over the last six months to a year, do you have some kind of broad outlines you can give on how quickly those trials might enroll and when we might be able to start seeing data from some of those kind of expansions into tumor-specific cohorts? We've not given guidance on timings for that, and we will give guidance on 2022 milestones and probably beyond at the beginning of next year. It won't include specific guidance on rates of accrual in those trials. Okay. Fair enough. Thanks for taking my questions. Later. Cheers, Mark. Your next question comes from Michael Schmidt with Guggenheim. Hey, guys. Good morning. Thanks for taking my questions. So I think you mentioned that you're, you know, initiating a new pembrolizumab combination study with the next-gen MAGE-A4 asset, which obviously makes sense. I was just wondering if there are any learnings from the initial trial that can be applied here in terms of the combination moving forward. Hi, Michael. Thank you. There are certainly learnings. I mean, you know, we should be learning from everything that we do as it informs, you know, our next steps. The real reason for us choosing to really change the focus of the combination to the next gen product is based on really at this point, having experience with the next generation product, seeing its improved potency and efficacy and wanting to put, you know, sort of the best combination forward. I think that's really the key point here. I got it. You know, the other question I had, perhaps related to the prior0 question just on CMC for afami-cel. I mean, we have seen a number of FDA, you know, BLA delays around manufacturing and CMC of T-cell products. Yeah, if you could maybe just provide some additional color in terms of what has to be done to really check the box on CMC for the BLAs. Yeah, this is John Lunger. I lead the CMC organization. A couple things there. One is we are obviously going through all the activities we need to do to prepare the Section 3 of the BLA. The supply of our commercial product will come from the same supply chain that we've used for the phase II trial. There's no changes in there, which I think is a big plus for us. We had interactions related to potency assays and all the release assays, frankly, and those are progressing well, and we feel confident that we've got the right assays in place, and we'll have them in place by the time we file the BLA next year. Oh, okay. Thanks. Last one, just around the Genentech collaboration. Obviously very interesting given their engagement with Adaptive as well. Just wondering how we should think about potential news flow coming out of that collaboration over the next, you know, one to two years or so. Yeah. Hi, Michael. It's Helen here in place of Marty. Nice to see you, speak with you again. We haven't disclosed specific when we'll have specific updates on the program, but clearly we anticipate that we will need to do that given our position and the importance of this deal to us and its progress and the fact that it's on a very long-term nature. We've only just passed HSR clearance, so I think it's a little early to give guidance on when we'll be updating. We hope that certainly during the course of the next year, we'll be able to sort of map out when we can provide more data and more information. Great. Thank you. Thanks, Mark. Your next question is from [Nick Abbott] with Wells Fargo. Hey, good morning. Thanks for taking our questions. Yeah, congratulations on a very good update. Very solid. You mentioned earlier we have Cohort 1 of SPEAR- 2, but there's also Cohort 2. So can you provide any details on how that is enrolling? Yep. W ithout. Do you want to take that? Yeah, without providing specific numbers, it continues to enroll well. You know, there's clearly interest in treating patients with afami-cel who have synovial sarcoma. That's the answer to the recruitment question. It's not intended to be, you know, part of the hypothesis testing for the filing, but will be supported from the standpoint of additional safety and efficacy, you know, considerations, as well as looking at specific subgroups. Terrific. Thanks, Elliot. In your prepared comments that you mentioned SURPASS-3 in ovarian cancer, is the intent I mean have you discussed the size of this trial with FDA? Is the intention to seek registration if it's positive? I think it's early to push the boat out too far on exactly what the trial looks like and to disclose conversations with FDA. You know, I think that's the answer. Yeah, thanks. Okay. Just going back to, you know, the next set of trials or the next trial with next gen afami-cel and a checkpoint inhibitor. I mean, in the prepared comments that statement is tied to SPEARHEAD-2. I know you're not gonna go into details, but is the plan here to test this in a broad range of tumors, or is it more as a replacement of SPEARHEAD-2? Yeah. Correct, Nick, without going into great details, it will likely be broader than just head and neck cancer. Okay. Specifically what tumor types, you know, are in the study we haven't discussed, but it is intended to be across tumor types, not just a single tumor type. Okay. Perfect. Great. Thank you very much. Thanks, Nick. Your next question comes from Soumit Roy with Jones Research. Hi, this is Daniel on for Soumit. First question would be, can you provide at least some color on the SPEARHEAD-2 as to since you dosed the trial, how many patients have been enrolled and when you expect data update? I think we have disclosed we have not enrolled any patients in that trial. If we haven't, we just don't have. That's one of the reasons why we're closing that now, so that we can get onto the more potent product in combinations with the more potent product. Got it. Thank you. Can you provide any color on the SURPASS-3? I know you said that you'll provide further details, but as you're moving on to ovarian cancer, are you going to focus on platinum resistance, or can you provide any details on that? Yeah. Elliot, do you want to touch on that? We haven't really given details with respect to exactly what the patient population, you know, will look like. The current trial is enrolling patients who are platinum ineligible. Not patients who are eligible to receive, you know, another cycle of platinum will typically get that from their physicians before being entered into a clinical trial. Excellent. Thank you very much. Your next question is from Mara Goldstein with Mizuho. Great. Thanks so much for taking the question. I just wanted to maybe drill down a little bit into the Allo program. I know you mentioned that you'll have manufacturing up later in 2022, but maybe you could talk a little bit about, if possible, the particular focus. I know the agreement calls for you to look at five different targets. Maybe if you could speak to us a little bit about that would be helpful. I'm just curious, just on the allogeneic program, given what we've seen, obviously, with Allogene's program and how you think about that vis-à-vis approaching FDA with your IND. Thanks, Mara. This is Helen Tayton-Martin again here. Just to talk to the Allo program, obviously we've made reference to building out our Allo manufacturing facility, but primarily in the first instance, that will be to support our internal MAGE-A4 Allo program. That will be the first into the clinic and the IND we signaled late 2023. You know, the Allo facility will initially be supporting that, but obviously the capabilities and the space will also support collaboration programs. I think that was the first question. I think in terms of focus, there is obviously, w e have a proprietary differentiation process from our edited stem cells to T cells that go through the process of scaling and cGMP transfer. There's still work to be done, hence having our own facility will be important as a component of that. I think in terms of the characterization work, which is really where it's relevant to the Allogene position, obviously that's a donor-derived product as opposed to a stem cell differentiated product. We know obviously it's a great team at Allogene. We know that they'll be all over the evaluation and the interactions with the agency. It will be important not just for us, but others in the field to stay close to that. I think we're quite, we have differences, though, around the stem cell characterization at every step of the editing process. That's always been important for our approach. I think that also gives, you know, perhaps, you know, an advantage in some ways in terms of knowing exactly what the characterization in terms of edits has generated at each step of the clone and differentiation process. So, you know, I obviously will pay a lot of attention, and it will be you know, important in our engagements with the FDA between now and our IND filing. Okay. If I could just ask a different question, which is that, as you're approaching the filing for the synovial sarcoma, how are you planning to layer in a commercial organization as you approach that filing period? Thanks, Mara. Helen again here. In terms of the preparation, as you would imagine, you know, given the plans on the SPEARHEAD-1 trial, the progress through it, we have been laying the groundwork for every dimension of commercial readiness, you know, obviously looking a long ways out. That obviously includes the work to prepare and scale in John's organization, and I'm sure you can touch on that too. We have also been looking very closely at what type of team we need, where we need them, when we need them, and have been building accordingly. There'll be more to come on that, I think, as we get closer to the BLA filing. All right. Well, thank you very much. Cheers, Mara. There are no further questions at this time. I will now turn the call back over to Adrian Rawcliffe for closing remarks. Thank you everybody for your questions on what has been a very busy quarter, and we look forward to being a very busy next 12 months. It's notable that the questions that you asked covered the broad spectrum of the activities that define Adaptimmune from our BLA file all the way through our mid-stage trials and into the earliest parts of our allogeneic platform. It's interesting that there's an increased focus, which I think is representative of the industry focus at this point in time on the CMC aspects and actually making the product, which I think speaks to the investment that we've made consistently over the last five years as we seek to build an integrated cell therapy company to deliver these potentially transformative therapies to patients. With that, thank you for your time today, and we look forward to future discussions.
