spk08: Thank you, Andrew, and good morning to all of you, and thank you for joining us. I'm pleased to review our progress for the first quarter of 2021. First, and before we get to the update on our programs, we're very pleased to see the progress in the US, the UK, and the EU with the COVID vaccinations, and seeing gradual decline of the case numbers. This bodes well for the conduct of our clinical trials as we move through 2021 and into 2022. With the expected opening of travel for vaccinated people between the US and Europe, we also expect flight operations to start to gradually normalize, which will relax the pressure on logistics. We continue to work hard with our supply chain and logistics teams, as well as our clinical centers, to ensure timely continental and transatlantic deliveries of leukophoresates, final products, and samples for analysis in order to support our clinical trials and ensure timely data availability and integrity. While we feel optimistic about the developments, we continue to monitor them very carefully with a particular focus on patient safety. In the fourth quarter last year, we provided data updates from the Phase I All-Cars Study at ASHE, The FELIX study is progressing well and remains on track with data expected in 2022. In Q1, we have received the INN for Auto-1 and can now be referred to as Obiceptactin autosal for Obicel. We also announced recently that we have received prime designation from the European Medicines Agency, again highlighting the innovative nature of Obicel. We're also exploring the potential of Obicel for the treatment of B-cell non-Hodgkin's lymphoma and we will have first aid at EHA in June. Our next-generation program, Auto 122, is being evaluated in pediatric patients with data expected for ASH at the end of this year. Phase 1 enrollment of Auto 4 continues, and importantly, we recently received an ILAP designation for Auto 4 from the UK Medicines and Health Products Regulatory Agency, the MHRA, which may potentially accelerate regulatory review of the development candidates. Moving on to slide number six to discuss the corporate highlights for the quarter. In January and February, we strengthened our balance sheet with the sale of ADSs under our ATM facility for net proceeds of approximately $15 million and also a public offering of ADSs, raising approximately $107 million in net proceeds. In January, we highlighted our focus on the Auto One program and the conduct of the Felix study. As part of this outlook, we announced our intention to partner our DLBCL program, Auto3. We also reviewed our commercial manufacturing strategy and decided to build on our manufacturing setup in the UK, being able to fully leverage our current manufacturing operations, experience, and skill, resulting in a more economical manufacturing platform while minimizing operational risk. In that process, we have terminated our lease of the U.S. manufacturing facility in Rockwell. Moving on to slide number seven. We would like to remind you of the clinical profile of Auto-1 and how it compares to the standard of care. The primary treatment option for patients is Blenatumumab, while inotuzumab may typically be used as a bridging therapy. If you look at the event-free survival, we are approximately twice as active as Blenatumumab at six months, and even at 12 months, we're at 52% for Auto-1 in terms of event-free survival, which substantially exceeds the six months value for Blinutumab at 31%. When looking at the Auto-1 data, it is important to realize that 70% of the patients had either received prior Blinutumab or Inutuzumab and failed on those therapies before entering the Auto-1 trial. Despite the elevated Auto-1 activity compared to Blinutumab, cytokine release syndrome and neurotoxicity are very comparable. Put very simply, with AutoOne, we're looking at a program that has at least twice the level of clinical activity to Blinnatumumab, which is the current standard of care, with a comparable safety profile. We believe that data is very strong and an excellent foundation to move our product into the registrational study. Moving to slide number eight, just another quick view on two of the key programs and products that are approved in the space, but from a commercial perspective. We'll look at a Blincyto or Blinotumab and Besponsa or Inotuzumab. As you can see, Blincyto reached in 2020 annual sales of 379 million. Typically, patients received an average of two cycles of the product, which translates to approximately 2,100 patients treated with this commercial product globally. Note that the majority of patients, approximately 1,800, who received the product are adults. We understand the key driver for sales accelerating into the fourth quarter, which was 29% year over year, was the expansion to the community hospital segment in the U.S. beyond the academic transplant centers where the product was initially launched in. While Blinzaita and ALL is moving to non-academic centers, we also expect the launch of Brianzi in the LBCL to establish car key experience in those centers. Both developments bode well for a product with the properties of AutoOne. Let's now turn to slide number nine. First off, obviously the auto one program at this point is in motion in the Felix phase one B2 pivotal study. It is a single arm study with approximately 100 patients with relapsed refractory disease. The primary endpoint is overall complete response rate. Secondary endpoints include molecular responses as well as eventually survival and duration of response. This program is ongoing and will recruit through the course of this year and into early next year. As I have mentioned, we're also conducting some additional studies to explore the activity of Auto-1 beyond the adult ALL population. That includes indolent lymphomas as well as other B-cell non-Hodgkin's lymphomas and chronic lymphoblastic leukemia. As mentioned earlier, we're also exploring the activity in primary CNS lymphoma, which is typically a neglected indication. In December, we also started a next-generation version of the Auto-1 program called Auto-1-22, that looks at minimizing the relapse rate in pediatric ALL driven by CD19 antigen loss. The Auto1-22 program builds on Auto1 with its unique properties and adds a novel highly active CD22 chimeric antigen receptor. We are planning to present data on this trial in the fourth quarter of this year. In summary, we believe there's a significant commercial opportunity to build on Auto1 and a franchise around the Auto1 program anchored in ALL both with adult and pediatric patients and have an opportunity to expand further into the B-cell non-Hodgkin's indications. Moving to slide number 10, Auto4 is our T-cell informal program currently active in the clinic, and we expect to have a clinical update by the end of this year and expect a good understanding by that point of the clinical profile of the product. The sister program, Auto 5, is prepared for an IND towards the end of 21. The medical need in T cell lymphoma is high, with very limited available treatment options for patients months relapsed after frontline therapy. Moving to slide 11. Always good to remind you all of the technology toolkit we have developed at Ovilus, particularly as it relates to the suite of next-generation programs, some of which you will recall we showcased at AACR last year. We're looking to move several programs into the clinic through 2021 and into 2022, including our first solid tumor programs, which we're very excited to be progressing. Our cell program models are designed to provide T-cells with a high degree of specificity and activity against cancer cells, while strengthening the T-cell's resilience to withstand the hostile environment cancer cells create to fend off T-cell attack. Slide number 12, as you can see, we have tabulated here the next generation programs alongside the expected phase one start dates. I would like to briefly highlight two of our programs. You will note, as discussed, we started the pediatric ALL clinical trial for auto 122 in December last year and are planning for a data update at the end of this year. We haven't yet mentioned, of course, Auto6NG, which we expect to start a phase one trial in children with neuroblastoma towards the end of 2021. This program builds on the positive clinical experience with Auto6NG published end of last year in Science Translational Medicine. All programs will initially be explored clinically in collaboration with our academic partners and will drive clinical news flow in 2022 and beyond. With that, I will turn over the call to Andrew for our first quarter 2021 financial update. Andrew?
spk02: Thanks, Christian. If we move to slide 14, it's my pleasure to review our financial results for the first quarter of 2021. So starting with our cash position, cash at March 31, 2021, totaled $239 million as compared to $153.3 million at December 31, 2020. In January of this year, the company sold 1.7 million ADSs under its open market sales agreement, resulting in net proceeds of $15.3 million. And in February 21, the company sold 16.4 million ADSs, representing 16.4 million ordinary shares, in a follow-on public offering, including the exercise in full by the underwriters of their option to purchase an additional 2.1 million ADSs. at a public offering price of $7 per ADS, yielding net proceeds of $106.9 million. Net total operating expenses for the three months ending March 31, 2021 were $39.9 million. That's net of grant income of $0.3 million. And that compares to net operating expenses of $38.6 million, net of grant income of $0.3 million, for the same period in 2020. Research and development expenses decreased to $30.7 million for the three months ending March 31, 2021, from $31.3 million for the three months ended March 31, 2020. Cash costs, which exclude depreciation and amortization, as well as share-based compensation, increased to $30.7 million from $25.6 million This increase in research and development cash costs of $5.1 million consisted primarily of, one, an increase in compensation and employment-related costs, which is net of lower capital costs, of $3.5 million due to a combination of an increase in employee headcount to support the advancement of our product candidates in clinical development and severance payments related to the reduction in workforce that began to take place during the quarter. Secondly, an increase of $2.2 million in facilities costs related to the continued scaling of manufacturing operations. And three, an increase of $0.4 million relating to cell logistics, which is offset by decreases in purchased materials in the amount of $0.6 million and project expenses of $0.4 million. Non-cash R&D costs decreased to $36,000 for the three months ending March 31, from $5.7 million for the corresponding period last year. The decrease is primarily related to share-based compensation expense, which decreased by $6.2 million as a result of forfeitures of incentive share options related to employees affected by the reduction in workforce. This was offset by an increase of in depreciation of $0.5 million. General and administrative expenses increased to $8.7 million for the three months ending March 31, 2021, from $7.6 million for the corresponding period last year. Cash costs, which again exclude depreciation as well as share-based compensation, increased to $7.6 million from $5.9 million. This increase of $1.7 million is related to an increase, firstly, of $0.4 million in facilities costs. Secondly, an increase of $0.6 million in legal fees and audit fees. And thirdly, an increase of $0.3 million of expenses related to preparations for becoming a commercial stage company. And lastly, an increase of $0.4 million in compensation and employment related costs related to an increase in headcount, as well as severance payments related to the reduction in workforce that I mentioned earlier. Not cash general and administrative costs decreased to $1.1 million for the three months ending March 31, and that's from $1.7 million for the corresponding period last year. The decrease is attributed to share-based compensation expense as a result of the lower fair value of stock auctions recognized during the period. Loss on disposal of leasehold improvements of $0.7 million relates to leasehold improvements no longer being utilized in the facility in White City in London. Interest income decreased by $0.5 million for the three months ending March 31, 2021 due to lower interest rates for cash held on deposit. Other income decreased by $3.7 million for the three months That compares to other income of $4.5 million in the corresponding period last year. There was a decrease of $5.6 million, primarily due to the weakening of the US dollar relative to the pound during the three months ending March 31, 2021. And that compares to the three months ending March 31, 2020, which is offset by gains on lease terminations of $2 million. That's net of any related expenses. Income tax benefit increased to $5.7 million for the quarter. And that's up from $3.7 million for the corresponding period last year. And this is due to increased research and development credits. As research and development credits grew at a faster rate than our net loss before income tax, this led to a higher effective tax rate. Research and development credits are obtained at a maximum of 33.5% of our qualifying research and development expenses, and the increase in the net credit was primarily due to an increase in those eligible expenses. Net loss attributable to ordinary shareholders was $33.3 million for the three months ending March 31, 2021, and that compares to $29.9 million loss for the same period in 2020. The basic and diluted net loss per ordinary share for the three months ending March 31 was 53 cents, and that compares to a basic and diluted net loss per ordinary share of 60 cents for the three months ending March 31, 2020. Our current cash on hand, which obviously includes the recent financings in January and February, will extend the company's cash runway into the first half of 2023. And now with that, I will hand the call back to Christian to give you a brief outlook on expected milestones.
spk08: Christian. Thanks, Andrew. And let me conclude this part of the management discussion on slide 16 with a recap of the major messages from today's call. The company is in a good position and combined with our cash on hand, we feel well poised for success. We're very excited about the auto one program. We continue to enroll into the Felix study in adult, adult patients with ALL and expect to report data in 2022. We started the phase one program for the auto one 22 product in pediatric ALL patients at the end of last year and expect first data to read out in Q4 this year. Additionally, We expect first data from the old CAR extensions program at EHA to give us first data on patients with non-Hodgkin's lymphoma. We're also planning to expand Auto-1 into primary CNS lymphoma with a CAR cell study, which is actually expected to start imminently. As indicated in our business outlook in January, this year we have announced a renewed focus on the Auto-1 program while intending to partner Auto-3 for the treatment of the LBCL patients. Additionally, we expect phase one data from our auto four program, our program for the treatment of patients with peripheral T cell lymphoma later in the year, and expect multiple next generation development candidates to enter clinical development over the course of 2021 and in 2022. Finally, with our successful recent race, we are in a position of strength with a cash runway into the first half of 2023. We're now happy to take questions. Operator?
spk05: At this time, if you would like to ask a question, please press star 1 on your telephone keypad. And your first question comes from the line of Maura Goldstein.
spk01: Great. Thanks so much. I'm wondering if, since we're expecting data on both the ALL programs starting in the fourth quarter of this year and then obviously the Felix program in 2022, if you could maybe just sort of wrap some color around what we should be anticipating in terms of number of patients, duration of treatment. And then secondarily, on the auto aid program, you're going into a BCMA direct car, and I'm just curious as to what your thoughts are from a competitive landscape perspective given, you know, the development in that space and whether or not you know, auto eight may to some degree suffer the same fate as auto three in terms of your prioritization and how you think about developing that.
spk08: Thanks, Mara. I appreciate the question. So first with regards to the work we're doing in the old car study to sort of explore the activities in the non-Hodgkin's indications as well as the carousel study for patients with primary CNS lymphoma. Um, those are exploratory studies. So we're basically having part of the old car extension. Uh, we having a courts of approximately 10 patients each and each of the sub indications. And that is what we're expecting to actually report on at the end of the year. So it gives us a, uh, overall will give us a nice, uh, additional set of patients. And I think we'll give us a good feel for the performance of the product, uh, that we're seeing across those various indications. On the pediatric study with the auto 122 program, obviously that's a classical phase one study as well. And we expect the study to be enrolled by the end of this year and data available by for all of those patients. In terms of follow-up, obviously the follow-up will be limited because most of these patients are being enrolled and treated during the course of this year. So we're looking at typically at a few months of follow-up for these patients on average. The third question or area that you were touching on is the AutoAid program and basically the competitive environment in the multiple myeloma space, now obviously with the approval of IDCell, but also the J&J program actually getting close to market as well. So what we're doing with this program, and again, this is a program we're running first through an exploratory phase one study on the academic side, is to actually evaluate whether indeed we can actually induce a high degree of deep responses in patients and whether we do see a good level of persistence of the product. Both, I think, we believe are characteristics that are important, to actually provide a product that has an opportunity for a differentiated profile. You're absolutely correct in asking the question, what about the profile that you actually need to meet? And clearly we do set a very high hurdle for a multiple myeloma program, given where the standard of care is, not just from a CAR-T perspective, but overall the standard of care obviously has been moving quite significantly over the last few years. and we clearly would need to actually see a good probability of inducing true long-term remissions in these patients, which has still been a challenge to induce with, frankly, any modality at this point in time.
spk01: Okay, thank you. And if I could just ask, Andrew, can you remind us on the ATM program, what is left outstanding on that program?
spk02: Yes, Mara, I can. It's around $80 million.
spk01: Okay, great. Thank you very much.
spk02: Thanks, Mark.
spk05: Your next question comes from the line of Matt Sibbes.
spk10: Hi, guys. Thanks for taking my question. Christian, I guess first, at EHA, which I think Abjects are even coming out next week, should we expect some data across all three cohorts from that all-card trial, or is it just mainly going to be indolent kind of updates beyond the four patients at ASHE?
spk08: Thanks for joining, Matt. The update will be focused on the Indolin cohort.
spk10: Okay, thanks. And then, you know, kind of following up on AutoAid, I guess the UCL posted the trial of a BCA-CD19 dual CAR for multiple myeloma. And just wondering if you're at a point where we can talk about the decision to use CD19 here versus maybe some of the newer targets, like bispecifics I've shown, such as
spk08: So the way we're thinking about the AutoA program is that the program is anchored through the BCMA car. The car that we designed there actually has quite a different binder in terms of properties as well to what has been explored so far in the space. and also uses a different actual design in terms of structural design that we're using for the receptor. So it's a significant change to certainly what we have initially in our Auto2 product, but also what we're seeing across the current programs that are being moved forward. So that's the anchor, basically, and what we're looking to get to is, as indicated, responses, which is really the hurdle that the FERC program needs to take first to sort of be moved forward. The next layer of questions that I think we need to address in the space is you actually get to a long level, an extended level of persistence, which has been actually quite challenging in multiple myeloma. When we look at the current programs, the data has been reported so far. So what we're looking to actually add is an element that actually gives us an extended persistence with the programs. And the third area actually will be to address the quite heterogeneous as well as challenging microenvironment that we find in multiple myeloma, a reason why this is still a disease that is basically we can buy time, but we have a hard time getting to a cure. So there's still remnants of tumors that we can't get to, and there's situations that were clearly very challenging to sort of actually for an immunological and frankly any other approach to currently crack. So those are the three layers that we're basically working on. And so in terms of the target antigen that we're using, there is an importance there is to actually drive persistence, which is a key aspect of it, and potentially actually support some of the driving cells that we see in multiple myeloma, be able to actually get at those, which may actually in part carry BCMA, but also maybe in part BCMA negative.
spk10: I mean, you kind of touched on this, but I mean, especially with the J&J product, I mean, the CR rates are extremely high. Do you think you can meaningfully, or I guess, is there an ability to meaningfully beat that as opposed to just wanting, you know, the real thing here is to drive better persistence to get that improved PFS beyond it, you know, moving it meaningfully beyond a year for PFS?
spk08: You're right in pointing out that obviously the CR rate per se is very high. But I think the more interesting part of the data is that the depth of the CR rate actually is correlated with the length of outcome. And what you need to drive towards are very deep responses, very stringent molecular CRs. And that is actually where you start to see differences, also differences between IDCell and the J&J program. And that is the area that you really need to actually drive at. So it's actually to look at a very high level of stringency in regards to the molecular CRs that you're actually looking at. And that gives you an early readout. And then you're right, the next level is very clearly that you need to actually drive for persistence and have an ability to actually keep the product active over an extended period of time. And the third aspect, as we're seeing in the space, is certainly also related to the overall safety profile that we're seeing as well.
spk10: Great. And kind of last broader question, given kind of what we've seen with Auto1 on the level of expansion and persistence and safety, do you keep that in mind as far as using a lentiviral system with this construct and, you know, just maybe with different SCFDs in programs going forward, or how will you manage kind of the different backbone, so to speak, of the programs?
spk08: I think in indications where persistence is important to sort of actually get to long-term benefits, we clearly do see a benefit of using the lentiviral backbones. And that's obviously what we're using in the context of, obviously, leukemia, as well as multiple myeloma. You'd also be looking at a lentiviral backbone. Okay. Thanks, Christian. Thanks a lot, Matt.
spk05: Your next question comes from the line of Gil Bloom.
spk09: Hello, everyone. Good morning. Thanks for taking our questions. So with the focus of manufacturing in the U.K., could this offer some logistical issues in treating patients in the U.S.?
spk08: Well, thanks a lot for joining, Gil. Very good questions. Obviously, we actually manufacture for our clinical trials currently out of the U.K., out of the manufacturing site that's located north of London in Stevenage. And we've been able to actually serve all the various geographies within the U.S., obviously, as well as across Europe, within the timeframe required to actually ship not only frozen leukophoresates, but also fresh leukophoresates. So we can actually manage the logistics very well even, and we're able to do that even during the most limited flight patterns that we had during the course of last year. So we don't think that actually that adds a significant component here in terms of either time or risk from a logistics perspective.
spk09: Okay, thank you. Maybe a little bit about Auto6NG here. So neuroblastoma in children is a relatively small market. Could you kind of remind us what the specialized features of Auto6NG, how those might translate across your solid tumor platform and, you know, learnings that you could have from a study in relatively small indication?
spk08: Right. So the Auto6 program, Auto6, started out with a chimeric antigen receptor targeting GD2 and was first asking the question, can we actually generate an adequate therapeutic window targeting GD2, understanding that there is a low amount of GD2 also present in pain fibers. And that basically, that question was answered through the first trial and was the publication that we had at the end of last year in Science Translational Medicine. The next question, however, is then, once you have an ability to target, is to actually address the challenges that are derived from the microenvironment that is present in neuroblastoma, and frankly, for that matter, in most solid tumors. What we're doing with the program is actually building quite significant level of resilience into the cells, into the CAR-P cells, and we do that in three different ways. On the one hand, we're actually rendering the cells insensitive to checkpoints or checkpoint signals by using an intracellularly available dominant negative version of SHIP2, which is a protein that transmits normally the signal from a checkpoint onto a T-cell receptor or a chimeric antigen receptor. The dominant negative version of it, of SHIP2, actually abolishes that signal transduction. And with that, basically renders the cells insensitive to that negative set of signals coming from checkpoint receptors. The second element is TGF-beta, which is certainly one of the ways in how tumor cells actually defend and fend off T cells and other immune cells over distance. Here we're rendering the cells insensitive to actually transmit the TGF-beta induced signal into the interior of the CAR T cell. We're using, again, the dominant negative version of a receptor subchain that is part of the TGF beta receptor. And the third element that we're adding is a constitutively active IL-7 signal, actually using a receptor that sort of actually gives you an IL-7-like signal on a constitutive basis. And what that does is it actually helps the CAR T cells to keep activated and actually, even if they receive negative signals from the environment, keep overcoming those IL-7, just as a reference, is also what we're inducing when we actually do the conditioning regimen, the short chemo stretch up from any of the CAR-T therapies. It's actually to induce IL-7 and IL-15, and obviously with the very same reason to actually help the CAR-T cells actually take hold at that point. And also in the case of actually having this signal engineered into the cells to actually keep them going, even if the environment actually is difficult to manage. Now, these three components I just talked through, obviously, are components that are relevant for any program, we believe, in the solid tumor setting. And hence, actually, the data that we're going to be generating in neuroblastoma will be important, not just for neuroblastoma, but across our programs also, that we've been working on towards other tumor entities as well. So I think that is sort of the important part. The reason why we're actually exploring these modules in neuroblastoma first is because in neuroblastoma we have a homogeneously expressed target antigen, the case of GD2, which actually takes one of the elements of variability out that you often have with tumor-associated antigens, which often are highly variable in their expression. Think about HER2 or EGFR as an example, which have a wide range of expression across cells within a given tumor sample. And that obviously creates a lot of challenges, in fact, if you try to interpret results you actually generate. So here we have a homogeneous background. It's a high medical need setting. It's a pediatric indication. There's obviously a very good fit with the pediatric work we're doing in ALL. from a center perspective, from a commercial perspective as well. But it also gives us a very good background and clean background to actually establish those additional modules and their utility in a solid tumor setting.
spk09: That was very helpful. And last one on the indolent lymphoma program. Could you remind us, how important is having a safer, lower CRS response CAR T product in this patient population, maybe with a look at competitive programs here? Thank you.
spk08: Thanks, Gil. This is a very important question because, obviously, when we look at the CAR T experience so far that we have through the initial programs that reached the commercial stage, is that although we expected the CAR-Ts to go very broad in a lot of the indications, DLBCL first, but then also now with approvals in follicular mantle cell, that we should be able to reach a large proportion of the patients. And the reality is we haven't been able to do that. The fundamental reason why that didn't happen is that actually managing the CAR-T therapy in centers outside of highly specialized transplant centers has been really difficult. and it's difficult from a handling perspective, from an infrastructure perspective, from a cost perspective. And so the adverse event profile, in fact, the neurological adverse event profiles of the products actually have significantly limited their commercial use and, frankly, have limited their ability to actually reach the majority of the patients in those disease settings. Now, if you go into a disease setting like follicular lymphoma or also mantle cell lymphoma or CLL for that matter, is that those patients very often are treated much more into the periphery, even more so than what we're seeing in DLD-CL as an example. And that actually creates a very significant need for an excellent safety profile so that indeed the therapy can be managed outside of the highly specialized academic centers. And that's really what is the core and what is needed in terms of the commercial translation of this therapeutic approach to reach a broader range of patients in the respective indications.
spk05: Your next question comes from the line of Eric Joseph.
spk03: Hi, good morning. This is Rahul on for Eric, and thanks for taking the questions. Just a couple from us. Firstly, on auto one, how do you assess its potential in the early line settings in adult DLL? I mean, what kind of response and durability would be seen as clinically meaningful relative to the existing treatment landscape? And then, is it safe to say that the initial approval would likely be in the third line setting followed by a potential label expansion based on the confirmatory phase three study?
spk08: So thanks a lot for joining and thanks for the questions. Obviously, while we're starting with the development for auto one in ALL is the last line setting. The challenge at that point that the patients have is that they've already experienced an enormous amount of cytotoxic agents. And as a consequence of that are both highly immune suppressed, but also are overall in a rather poor condition because of the high level of cumulative toxicity they've been exposed to. So, in that sense, it creates actually a very difficult population to deal with, both from a safety perspective, but also from a disease perspective, because obviously with every line of therapy, you keep selecting the cells that withstand, obviously, that particular line breakthrough, and actually at that point, obviously, are more difficult to treat. And so... starting at the last line setting and actually showing a significant level of activity in this last line setting, bodes extremely well in terms of the potential of the product in an earlier line. This was also exemplified very nicely by the experience in adult ALL patients with glenotumor maverick in psycho, where the last line or third line data was showing a complete permission rate of approximately 42%. However, in frontline consolidation in patients who actually have gone through frontline induction chemotherapy consolidation cycle one, and at that point still have minimal residual disease, which was obviously resistant to chemo. In that patient population, Blincyto actually showed 78% complete remission rate. So in other words, what we're seeing is that as you move up, and this is obviously also T-cell mediated activity, as you move up, we would expect actually that the activity we're seeing and the benefit that we're seeing induced in the third-line patients to substantially improve as we go into an early line of therapy. And that is what we would expect to see. And clearly, in terms of the settings that you can think about is similar to what I just said with regards to frontline consolidation of high-risk patients is one setting you might want to go. Or you could also contemplate a more classical second-line setting either in patients that are ineligible for transplant or patients that are eligible for transplant. Those are the basic settings that you can choose to actually move the product into an earlier line of ALL therapy.
spk03: Thanks. Thanks for the call. And then on auto three, can you maybe clarify if the phase one to Alexander study is a store for additional data readouts and news flow in 2021? such as survival follow-up and safety data from the outpatient cohort?
spk08: Right. So on the auto-free program, we're in the process actually of writing up the data in a publication. Given that we obviously had four oral presentations of the data last year, we feel it's the right time to actually now show the full picture of the data, which is, you know, only possible in a limited way and 10-minute presentations and hints for moving to a publication, which we're hoping to publish during the course of this year.
spk03: Great. Thanks for taking the questions.
spk08: Thanks a lot. Appreciate it.
spk05: Your next question comes from the line of Kelly Shi. Good morning.
spk06: Thank you for taking my questions. I have a question regarding auto fall in T cell lymphoma. So what kind of patients to enroll on this trial, and what does the competitive landscape look like? Also, for the ASH update at this year end, should we expect to see meaningful efficacy readout? Thank you.
spk08: Thanks a lot, Kelly, for joining. So the patients we're enrolling in the auto four phase one trial are patients with peripheral T cell lymphoma, that have failed, obviously not just the frontline therapy, but typically three lines of therapy before they actually get onto our trial. So these are very advanced patients that we're enrolling into the trial. What we're expecting to see towards the end of the year is obviously we're going through the dose escalation with the program, and we expect data from currently what we would assume data from three dose levels at that point in time potentially a bit more than that. But that's sort of the ballpark that we're looking at. So we're looking at the dose escalation and obviously the readout related to that. In terms of the data that we expect to see is obviously safety data as well as other tumor assessments in those patients and pharmacological, pharmacodynamic type of data, which would give us a good understanding of the performance of the product in that setting. From a competitive perspective, at this point, obviously, the competitive environment in BTCL late-stage setting is rather limited. There's obviously the subset of patients that are CD30 positive, which are eligible for pentoximab, which is unfortunately only a small portion of the patient population. For the patients that are not eligible for pentoximab, obviously, the current opportunities are predominantly actually to participate in clinical trials. So in that sense, there is not, from a commercial perspective or a therapy perspective on the market, there is a very small sort of set of agents that are currently available, predominantly related to high-dose chemotherapy, potential transplant, and if you're CD30 positive, printoxin.
spk06: Thank you very much. I also have a follow-up for Auto6. I'm just wondering, so for the safety switch incorporated in the CARV, At what juncture would a physician be allowed to trigger the safety switch?
spk08: So when we designed the original Auto6 program, obviously the question that we had was really a question about the safety of the product and whether indeed we could get actually to clinical activity without inducing significant neurological toxicity, in this case a very major pain syndrome. And because we couldn't predict whether or not our hypothesis around design actually would be working out, obviously we did put a off switch into the product which would allow the product to be eliminated should that become a necessity. With the product actually having gone through the initial exploration in phase one in neuroblastoma patients and without actually inducing that type of toxicity, I would expect that it's quite unlikely that a physician would actually want to use the switch, and certainly we didn't have a need to use it. I think in general, when you actually offer switches, build them into your product, it's really the physician's decision. And it's the physician's call in the end whether or not to actually, frankly, abort the therapy, which is what it is. In this case, you would be providing a dose of rituximab, which would take out the CAR T cells, at which point you literally abort the therapy. So you do that clearly if you have indication of a significant level of toxicity that you have a hard time controlling. But this is ultimately the decision of the treating physician where, frankly, that decision has to reside.
spk05: Thank you very much.
spk08: Thank you.
spk05: Your next question comes from the line of Estika Goonwarden.
spk07: Hi. Hi, guys. Thanks for taking my questions. I've got a couple on AutoAid, if I may. Christian, can you talk about the design features of the car that could help you get more of those stringent CRs or more patients into MRD negativity? And then... What items in your toolkit are you incorporating that could help Auto-Aid overcome some of the suppressive factors in the tumor microenvironment? And then I have a follow-up on Auto-One.
spk08: Okay. Well, thanks a lot, Jessica, for joining. What we really were working towards and what the design work that we've done on the receptors actually was geared to is to get to a very high level of cytotoxic activity of the product against multiple myeloma cells that express very low amounts of BCMA. What we had published earlier is that the range of BCMA expression can vary quite a bit in these patients. It can be as low as 10, 20 receptors per cell up to, you know, in the low test of receptors per cell. But in general, it's an order of magnitude, two orders of magnitude below of what, as an example, E19 would be. So the real challenge is how do you get to these cells that actually express very low amounts and to sort of still be very active on those cells. And that is really the test that we applied. And we did actually test a range of different types of pinders as well as designs on the receptors for exactly that ability to give us a very high level of activity against those multiple myeloma cells that express very, very low levels of BCMA, and it still has to work there. That's really the optimization that really was driving the selection for those features on design, et cetera, that would give you exactly that outcome. So it was a series of designs tested for that particular outcome, and that is actually how we sort of actually addressed the fundamental question that we believe is at the heart of the improvement that needs to be done, With regards to the toolkit, I think what I just went through with regards to the key elements that we're using as an example for the Auto6NG program, actually those elements all we believe would be relevant as well in the context of multiple myeloma. The exact composition we haven't disclosed at this point, but I think any of these modules actually would be, we believe, supportive in terms of activity and drive further activity in that setting.
spk07: Great question. And then, so just to go over into auto one here. So there's data that suggests that the upfront response may be a driver of durability in DLBCL. Do you think there's data in the public domain that suggests that this also is the case with indolent lymphoma? Or is persistence something that's more important in this setting? To put the question another way, I'm trying to figure out How does Auto1 do better than, let's say, AxiCell, which also generates some data in interload?
spk08: Right. So it is an interesting question, actually, in terms of depth of response. I think the best data and also correlative data with outcome that we have across the B-cell malignancies is actually in ALL, where we have excellent data sets that actually show the impact of molecular responses and the importance of reaching molecular responses to outcomes, whether you're looking at patients who do receive subsequent transplant or whether you look in the context, obviously, of other therapeutic modality. But getting to a molecular response is critical for a chance to actually have a long-term outcome. If you don't achieve that, your disease will come back very, very quickly. The data set that we're seeing in multiple myeloma starts to point quite a similar way, as we talked about before, and I think it sort of gives us a very similar picture. I think that we're starting to gain more information around non-Hodgkin's lymphoma more broadly, but the data sets are probably not quite as strong yet in terms of the correlation between the molecular remission as well as the long-term outcome. It's just data that is still actually being generated. But in general, I think there's a sense that getting to very deep responses matters, obviously, in a significant way in these disease settings. With regards to follicular lymphoma, I don't think there is enough data to use it as a guide quite yet. But I guess we're looking into the next two or three years. I would expect the field will start generating much more substantive data sets that will get much more conclusive answers around the correlations. of molecular emissions and durability of response in those settings as well.
spk07: Great.
spk05: Thanks, Christian. Your next question comes from the line of Robert Burns.
spk04: Hey, everyone. This is Chase for Rob. My first question is on Auto 8. So thanks for the color on the optimized design. And do you think that would potentially help in eliciting lower CRS and neutropenia than something like J&J's asset, which showed pretty high rates in its Phase I study? And do you think the field has evolved to manage some of these toxicities? In other words, you know, are these a major barrier to adoptions? And a quick question on auto one allogeneic program. Can you provide like an update on when you're potentially going to initiate a study and type of patients and maybe even the target? Thanks.
spk08: Thanks a lot for joining, Jake. The question related to sort of multiple myeloma and the type of safety signals that we're seeing, I think that what we're obviously having multiple is a disease that actually is present, similar to ALL, it's present in the bone marrow. And it has significant impact on sort of the health of the bone marrow of the patients. And that obviously can drive, ultimately has an impact on cytopenias, et cetera, and prolonged cytopenias, of course, as well. So I think we have an element here that's intrinsic to the disease. We're then obviously working with therapeutic approaches that actually are highly active and have to be highly active in the marrow and can drive significant levels of cytokines in these patients in the marrow as well, which can have actually a negative impact on the bone marrow's ability to regenerate. I think what we'll have to see, and we probably need a bit more data on that in general in the field is, At this point, does the marrow actually start to recuperate and sort of actually start to compensate and basically rebuild its ability to properly function? That is something I think that we just need more data on, and I'm not sure there's a good lead at this point that will give you a sense around design premises, et cetera, that you need to actually look at to improve the outcome with regards to these types of toxicities. The second question that you raised was related to the activity that we're having on the allogeneic side. The program that you're referring to is also one, obviously, that is in collaboration with our academic partners. And we expect that program to actually get going towards the middle of the year. And we'll report at that point in time and give an update kind of on where we're going with the program. So, we'll still need a bit of time here to actually before we're going to start talking about it in more detail. But our program is obviously on track to be initiated during the course of this year and on the clinical side. Thanks. Thank you.
spk05: At this time, there are no further questions. Do you have any closing remarks?
spk08: Well, first off, thanks a lot for joining. Really appreciate your continued interest and support, and we're looking forward to keeping you updated. Obviously, next key update for us will be at EHA. All right, thank you very much. Have a great day.
spk05: Thank you for participating. This concludes today's conference call. You may now disconnect.
