Good day, and thank you for standing by, and welcome to the Innate Pharma 2021 First Quarter Business Update Conference Call. [Operator Instructions] I must advise you that this call is being recorded today, Tuesday the 11th of May, 2021. I would now like to hand the call over to your first speaker today, Dr. Mondher Mahjoubi. Please go ahead, sir.

Mondher Mahjoubi

Analyst

Thank you. Good morning, good afternoon, and welcome, everyone. This morning, Innate issued a press release providing a business update for the first quarter 2021. I look forward to explaining the progress made during the quarter, as well as addressing future goals and milestone. The press release and today's presentation are both available on the IR section of our website. Please move to Slide number 2. And before we start, I would like to remind you that we will make forward-looking statements regarding the financial outlook in addition to regulatory and product plan development. These statements are subject to risks and uncertainties that may cause actual results to differ from those forecasted. Please move to Slide number 3. On today's call, I'm delighted to be joined by Dr. Joyson Karakunnel, EVP and Chief Medical Officer. I would also like to take this opportunity to welcome our new CFO, Frederic Lombard, who officially started at the company in April and will join the Q&A section of this webcast, which will follow the prepared remarks by myself and Joyson. As you may have noticed, in the past, we have only held conference calls marking our half-year and annual results. However, in order to provide more regular updates on our business progress, we have decided to hold conference calls on a quarterly basis. It's important to note, though, that as we do not publish full quarterly financials, there will be no formal remarks about our financials during this call or the third quarter call. On Slide number 4, you have the classic intro slide of Innate Pharma. We are pioneer in the field of innate immunity, as you know, and NK cells. And we follow the science to develop innovative therapeutics for patient, leveraging our know-how and antibody generation platform. We are using…

Thank you, Mondher. On Slide 8, let me start with lacutamab, our first-in-class humanized monoclonal antibody that targets the immune receptor KIR3DL2. As you may remember, KIR3DL2 is an inhibitory receptor found in approximately 65% of patients across all cutaneous T-cell lymphomas and even more in certain aggressive subtypes, but with limited expression in healthy tissue. To date, data from lacutamab have shown promise, demonstrating compelling single agent activity and offering immense potential in lymphomas historically associated with a poor prognosis for which there are few therapeutic options at the advanced stages. On Slide 9, as Mondher mentioned, this past quarter we hosted a virtual investor event featuring key opinion leaders in cutaneous and peripheral T-cell lymphomas. During this event, we highlighted both the unmet need in these populations as well as the therapeutic rationale for our TELLOMAK study, evaluating lacutamab in subsets of CTCL. Additionally, we introduced a broad development strategy to advance this program initially for Sezary syndrome, a niche CTCL indication with high unmet need, into other forms of T-cell lymphomas, notably mycosis fungoides and the broader PTCL population. On Slide 10, let me first highlight the progress in our ongoing Phase II TELLOMAK study for Sezary syndrome and mycosis fungoides. We were pleased to share that we had moved the KIR3DL2-expressing mycosis fungoides cohort from stage 1 to stage 2, clearing a predetermined threshold before 50% of the cohort was enrolled. This was very encouraging. And I'm pleased to announce that the preliminary data from the stage 1 of this cohort will be presented by Dr. Martine Bagot in an oral session on the 22nd of June at the 16th International Conference on Malignant Lymphoma, ICML, Lugano. And this year, it is being held virtually. For the Sezary syndrome cohort, enrollment is on track, and we…

Thank you, Joyson. As you can see, we are working diligently to execute across all our strategic pillars and believe that we are laying the groundwork to drive near and long-term value for patient and shareholders. Looking at our clinical program, we expect to achieve a number of milestones over the next 18 to 24 months. As you've heard from Joyson, our Phase II TELLOMAK study for lacutamab continues to progress, and we expect to share preliminary data from stage 1 of the KIR3DL2-expressing MF cohort at the Lugano meeting in June as well as expecting to report potentially pivotal data in Sezary syndrome in 2022. In addition, we anticipate moving our monotherapy PTCL program into the clinic by midyear with initial data expected in 2022, with the combination studies sponsored by LYSA expected also to start in the second half of this year. In parallel, we continue to develop our NKCE technology platform, and we are very encouraged by the preclinical results for our next-generation NK cell engagers. We believe that this represents a natural evolution of our platform, illustrating the potential of natural killer cells to be a potent cellular player for the next generation off-the-shelf cancer immunotherapies. And we look forward to Eric sharing more details on the innovation we have made at the FOCIS meeting next month. Highlights, as you heard from Joyson of the next-generation NKCE platform, together with the lacutamab MF data presented at Lugano, will also be presented at an online IR event to be held on June 23. Details for accessing the event will be posted on to our website in due course and publicized via our usual channels closer to the date of the event. Lastly, we are also very pleased to have such productive collaboration with industry and academic partners to advance monalizumab and avdoralimab alongside early stage programs such as IPH6101. In addition, as you have seen, we are well capitalized to deliver on our ambitious development goals and look forward to keeping you updated on our progress throughout 2021 and beyond. That concludes our prepared remarks. We will now open the call to question. Operators, please can you start with the first question?

Operator

Operator

[Operator Instructions] Our first question comes from the line of Yigal Nochomovitz from Citigroup.

Yigal Nochomovitz

Analyst

I had a question about the positive early signal that you've seen in the KIR3DL2-expressing MF cohort. My question is, can you speak to the durability of these responses that you've seen so far? And was there any correlation between the degree of expression of the target KIR3DL2 and the responses?

Mondher Mahjoubi

Analyst

Very important question, indeed, about the quality of the response we achieved with lacutamab. Before I hand over to Joyson to give you more details, as you may remember from the Phase I study published about now 2 years ago in Lancet Oncology, the duration of responses and even disease control, including progression-free survival in the Phase I was quite impressive in the range of 11 to 12 months. So not only lacutamab could have generated a significant tumor shrinkage in the range of 45%, but with durable responses in Phase I. And of course, we look forward to sharing with you these data soon in the next couple of months. But keep in mind that the stage 1 was essentially about the tumor shrinkage. That's what basically triggers the move from stage 1 to stage 2. Now I'll leave it to Joyson to provide more color about this question.

Joyson Karakunnel

Analyst

Thank you, Mondher, and thanks for the question. So I think when we look at this, we -- I would look at it similar to what Mondher was just mentioning. In the Phase I study, we talked about the duration of response with the Sezary syndrome or the -- and that, as Mondher was mentioning, was longer than the benchmarks at that time. I think when we look at the mycosis fungoides stage 1 cohort, the key things to remember here is that the stage 1 to stage 2 was dependent upon response, and due to that, we would be showing early data. I think what we are trying to also do is -- what we're also trying to do is show you the totality of the data. So I think during Lugano, what you will be able to see is both the KIR3DL2-positive as well as the KIR3 -- the non-expressing KIR3DL2 cohort totality. This will be early data, so clearly, we may not have as much follow-up as we would like. But that's what we're hoping -- that's what we'd be presenting at Lugano.

Yigal Nochomovitz

Analyst

Okay. So based on the data at Lugano, we will have some sense as to how well the response correlates with the expression of KIR3DL2?

Joyson Karakunnel

Analyst

Yes, I think it will be -- so it will be very early data, but yes, I think you will get a sense of that.

Mondher Mahjoubi

Analyst

Yes. So Yigal, let me maybe rephrase your question to make sure we understand it. There are 2 cohorts in this MF trial: the KIR3DL2-positive expression and KIR3DL2-negative. The stage 1 to stage 2 translation we talked about is in the KIR3DL2. So in the patient population that express the tumor antigen. So the level of activity that we will be presenting is in the KIR3DL2-positives. So we won't be showing data in the KIR3DL2-negative so far because we are still -- it's still ongoing.

Yigal Nochomovitz

Analyst

Okay. I understand.

Our next question comes from the line of Daina Graybosch from SVB Leerink.

Daina Graybosch

Analyst

Two for me. First, do you have any data, any updates on when we could see monalizumab data, in particular, anything from the ongoing lung cancer trial? And the second question is whether you guys see a role for NK adoptive cell therapy to be combined with your NK cell engager program, and if you know whether Sanofi has any plans to look at the combination, given their recent acquisition of an NK cell therapy company, Kiadis.

Mondher Mahjoubi

Analyst

Thank you, Daina. Great questions, in particular the second one. The first one, I'm sorry to disappoint you. But as you know, this trial in particular, the COAST and NeoCOAST trial are trials sponsored by AstraZeneca, and I do not have more information than what they disclosed publicly, which is that they plan to present this data in the second half of 2021. So we are really looking forward to seeing this data in the second half of 2021. For the second question, I'll start, and please, Joyson, chime in. I think what we have seen at the last AACR and what was published already by the MD Anderson team last year is very encouraging and makes a lot of sense to somehow boost the NK cell engager platform or NK cell engager antibodies with fresh cells that you infuse in the same time. So it makes a lot of sense. Of course, we cannot speak or speculate on what Sanofi's strategy is in this field. I think the obvious next step is, of course, to move IPH6101 into the clinic and start the Phase I. But I can tell you that we are looking at this field very carefully and very excited about the prospect of having this combination that seems at least in heme malignancies to produce a quite spectacular tumor shrinkage and clinical benefit. Joyson, would you like to complete or add anything on this question, as well as on to monalizumab, if you know more no?

Joyson Karakunnel

Analyst

No. I have to say, monalizumab, I think you summed it up very well. And also on the second question, I think that was a great summary and I have nothing more to add.

Daina Graybosch

Analyst

Thank you for that. You know I have to ask about those lung trials every time.

Mondher Mahjoubi

Analyst

You have to. I mean, Daina, if you don't ask it, I would be surprised. Thank you.

Joyson Karakunnel

Analyst

We'll just predict the question from now on, say Daina --

Our next question comes from the line of Swayampakula Ramakanth from H.C.W.

Swayampakula Ramakanth

Analyst

This is RK from H.C. Wainwright. In terms of the NK cell engager program with Sanofi, so we know that the first one is getting into the pre-IND studies. On the second molecule that potentially Sanofi can take into development, would that also be against the same target, in the sense, NKp46? Or it could be against the other targets that not only you, but other folks are also looking at?

Mondher Mahjoubi

Analyst

I think -- I believe you know that NKp46 is an activator receptor expressed on NK cells, and it's one of the most specific and stable activator receptor for NK cells. Unlike many others, I know to mention NKG2D or CD16, we know that those receptors eventually may get down regulated when the NK cells are traveling to the tumor microenvironment. Here we are talking about really a very specific and very stable. And I think it's important for us to highlight the fact that our platform is basically versatile by the fact that you can change tumor antigen, but we are extremely delighted actually with the proprietary platform we developed around NKp46. So the various partnerships that we will be developing, including the second program that we have with Sanofi, is still used in NKp46 as an activator receptor, but a different tumor antigen that Sanofi did not want to disclose at this point in time. So it's the same technology as for the first one, 6101, but with a different tumor antigen. And beyond Sanofi, again, we are developing both proprietary but also a partnered multi-specific, again, keeping NKp46 and changing the tumor antigen depending on, of course, the collaboration and the partner that we are working with. In addition, as you've seen in Joyson's last slide, what Eric Vivier will be presenting next month at the FOCIS is basically even the next-generation of multi-specific NKCE, what we call NKCE-4, where we are still leveraging the NKp46 platform, but trying to ensure that we have even a more potent and efficient antibody targeting different tumor antigen. I hope I answered your question.

Swayampakula Ramakanth

Analyst

Yes. Yes, you did. And then going into the clinical programs, especially the one with lacutamab in PTCL, as you stated, you're initiating the monotherapy and the GEMOX combination is starting -- being started by LYSA group. However, for the combination with the CHOP, do you need to see the data from your monotherapy study before you embark onto the CHOP combination? Or you're basically staggering these studies and don't have to wait for all of the data from the monotherapy to come out?

Mondher Mahjoubi

Analyst

Yes. Again, very, very important question that will give Joyson the opportunity maybe to remind you a little bit the strategy behind the selection of the monotherapy approach, our strategy in relapsed PTCL. Joyson, would you like to take the question?

Joyson Karakunnel

Analyst

Sure. So I think -- so when we look at the strategy for PTCL, we are targeting, first of all, KIR3DL2-positive patients. And that's going in with the at least early data that we've seen in the mycosis fungoides cohort based on that hypothesis. Now when we look forward in time, what we would see is that the monotherapy will -- there's 2 approaches that we could take. One is sort of -- and I'm specifically talking about an earlier line setting, which would be a CHOP combination. And for that, what we would -- what we'd like to do is, one, we could -- we would be waiting for the totality of the monotherapy data before beginning the first-line setting. Or to your point, we could stagger it to where what we would do is basically, as we start to see the data from the monotherapy single arm study, we would begin to, if the data is very encouraging, start the earlier line setting at that point. So there's definitely those 2 approaches that are possible, and we're considering both of those as we start these trials and start looking at the data.

Our last telephone question comes from the line of Liisa Bayko from Evercore.

Liisa Bayko

Analyst

Just a couple questions for me. First of all, for the PTCL study, do you envision that sort of following the general design of TELLOMAK, or can you maybe speak to how you're thinking about the design of that study?

Mondher Mahjoubi

Analyst

Joyson? Okay. Go ahead.

Joyson Karakunnel

Analyst

So we're considering all approaches at this point in time. But at this point, at least as the data in the mycosis fungoides starts to evolve as well as we're placing our bets on the KIR3DL2-positives. Now that's without -- that's not saying, of course, as we start to see longer term data, especially in the mycosis fungoides where we may reevaluate our strategy, and it starts to look more of like the TELLOMAK where we have an expressers as well as non-expressers. I think it's very early, but we are definitely keeping all those approaches in mind. So one, to look at the monotherapy in the KIR3DL2-positives and only look at that subset. Number two, continuing to evaluate the mycosis fungoides in the TELLOMAK study, especially the longer-term data, and considering putting in a non-expressing cohort into PTCL, and then as also the combination. So not only is LYSA running a chemotherapy combination, but we would also be looking other standard of cares that are available in the U.S. in combination, depending upon the PTCL data. I hope that answered the question.

Liisa Bayko

Analyst

Yes. And can you maybe describe a little bit more on kind of the non-expressers, what would be the rationale for activity there?

Mondher Mahjoubi

Analyst

Go ahead, Joyson.

Joyson Karakunnel

Analyst

So I think when we look at the non-expressers, I think, if I understand the question correctly, you're asking if you were to see expression, why would you -- why would you expect to see expression in the non-expressers considering the mechanism of action of lacutamab? And what I would say is I think it goes to what we see with a lot of biomarker subsets, and that is tumor heterogeneity. That's number one. And then number two is sampling error. So I think both of these can lead to sort of the, I guess you could say the sensitivity. Not only the sensitivity of the test being able to pick up, which we're confident about that. But more importantly is that are we sampling, or is it heterogeneous and that's why we're not picking it up?

Liisa Bayko

Analyst

Okay. Understood. For 6101, can you maybe talk about what kind of IND-enabling work you're doing and when we can expect that to enter the clinic? It's -- we're excited to see more about the NK engager platform.

Mondher Mahjoubi

Analyst

So Liisa, as you know, the 6101 program is fully under the responsibility of Sanofi. They are conducting the classic IND-enabling studies with the ambition and goal to start the clinic as soon as possible. So we do not have any data or comments to disclose at this point in time about what Sanofi's doing to move this drug into the clinic.

Liisa Bayko

Analyst

So it's kind of really, it's on their hands in whatever -- they have plans to disclose the preclinical stuff. They don't normally do that. Okay. Do have any sense of when that will start clinical development?

Mondher Mahjoubi

Analyst

The announcement early this year is, I would say, a testimony for their interest to move this to the clinic as quickly as possible. And you know the usual process and what type of IND-enabled study. So the plan is to go as fast as possible, but they did not disclose specific dates.

Liisa Bayko

Analyst

Okay. Fine. Thanks a lot.

Operator

I'd now like to hand the call back to you, sir, for your webcast questions.

Mondher Mahjoubi

Analyst

Yes. Thank you. Actually, I have one question from the webcast. It's update on the FORCE time line. FORCE is the randomized Phase II study that is testing the potential role of avdoralimab in the treatment of COVID-19-driven pneumonia. As you know, this is an investigator-sponsored trial, and it's currently ongoing. I cannot give time lines or further details about the progress on this study as Innate is not responsible for the running. I can only say that the trial has completed enrollment and is ongoing for patient follow-up and data analysis, and we'll share with you this data as soon as they become available. That's what I see on the webcast so far. Okay. If there are no more question, I would like to thank you all for joining this call. And I look forward to our next investor relation event in June to update you on the progress of our portfolio, especially on the NK cell engager platform as well as the lacutamab data in mycosis fungoides patients that will be presented at the Lugano meeting. With that, I close the call and thank you very much. Have a good day.
