Questions via the webcast can be submitted online. I would like to remind all participants this call is being recorded. Without further ado, I am pleased to introduce Henry Wheeler, Vice President, Investor Relations and Communications. Henry, over to you.

Henry Wheeler (VP of Investor Relations and Communication)

Thank you. Good morning, good afternoon, and welcome everyone. This morning, Innate issued a press release providing a business update for Q1 2023. We look forward to highlighting the progress made during the year to date, as well as addressing future goals and milestones. The press release and today's presentation are both available on the IR section of our website. On slide two, before we start, I'd 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. On slide three, for today's call we will be joined by Mondher Mahjoubi, our Chief Executive Officer, who will then hand over to Joyson Karakunnel, our Chief Medical Officer, who will cover updates on lacutamab and monalizumab.

Yannis Morel, Head of BD and Product Portfolio Strategy, will then cover some ANKET updates and BD, who will then hand over to Mondher for close. We will also have our CFO, Frederic Lombard, on the line for questions. Mondher, I now hand over to you.

Mondher Mahjoubi (CEO)

Thank you, Henry. Good morning, good afternoon, everyone, welcome to this call. Let's maybe move to slide four first to remind everyone what is our strategies. As you know, we are early clinical stage company. Our business model centers around 3 key priorities, where we look to drive value from our early R&D efforts to later stage partnership where it makes sense to do so. Our ambition is to develop innovative drug candidates that contribute to transform cancer care through a very strong pipeline of differentiated antibodies. First, we look to create near-term value driven by our lead proprietary asset, lacutamab, which is in development for T-cell lymphoma, with final cutaneous T-cell lymphoma results expected to happen in the second half of this year. Early peripheral T-cell lymphoma data are on the way.

Second, we continue to fuel our pipeline and create longer term value by leveraging our antibody engineering capabilities to develop novel molecules with a primary focus on our multi-specific NK/T cell engager proprietary platform we call ANKET®. As we develop antibody targets for our ANKET® platform, we recognize some of these binders may be more applicable for antibody drug conjugate technology. We look to further leverage our expertise in these settings. Last but not least, we are building a strong and sustainable foundation for our business with various partnership across industry and academia. Here, our AstraZeneca partnership with monalizumab is continuing in early stage non-small cell lung cancer. Our focus remains to leverage the value of our assets as much as possible. We want to ensure that if we can gain valuable competencies via partner agreement, we will consider that in our development plans for the product.

This will further validate our science and offer capital that we can reinvest to advance our early R&D engine. Before I hand over to Joyson, slide five, you have an overview of our pipeline, which shows, A, how we are continuing to translate our science into a robust portfolio of both proprietary and partnered assets. It also illustrates how we are executing against our strategy with our lead proprietary assets, lacutamab, the ANKET portfolio with the lead candidate 65, and also the emerging ADCs. In the bottom of this slide, we have our partnered products with AstraZeneca, Sanofi and now Takeda from late to early stage development. As you know, we anticipate a series of potential clinical readouts and catalysts in the upcoming couple of years as our R&D engine continues to leverage our scientific know-how to create a sustainable business.

I would like now to pass the call over to Joyson, who will review the progress made with our portfolio, starting with lacutamab, our most advanced proprietary asset. Joyson, over to you.

Joyson Karakunnel (Executive VP and Chief Medical Officer)

Thank you, Mondher. On slide six, let me summarize the progress we are making with lacutamab. We are pursuing a fast to market strategy for lacutamab in the niche setting of Sézary syndrome, where lacutamab was granted FDA Fast Track designation and EMA PRIME designation in 2020. We have expanded past Sézary syndrome to mycosis fungoides, where we have seen encouraging preliminary data from our phase II trial in both cohorts. For the Sézary syndrome and mycosis fungoides, enrollment is on track, and the final data is due for both cohorts in the second half of 2023. Finally,

Operator (participant)

Ladies and gentlemen, this is the operator. We are currently experiencing a short technical difficulty. Your call will resume shortly. Until that time, your lines will be placed on music hold. Please stand by.

This presentation will now resume.

Joyson Karakunnel (Executive VP and Chief Medical Officer)

I apologize there for the technical difficulty. Let me go ahead and continue where I had stopped off. For the Sézary syndrome and Mycosis fungoides, enrollment is on track with final data due for both cohorts in the second half of 2023. Finally, we are continuing to enroll into peripheral T-cell lymphoma in the phase I-B and II monotherapy and combination trials in the relapse setting, with initial data expected later this year. On slide seven, we have the preliminary phase II data published last year in Sézary syndrome and Mycosis fungoides.

On the top half of the slide in Sézary syndrome at the ASH Annual Meeting in December of 2022, the presentation showed that in this heavily pretreated post-mogamulizumab patient pool with a median prior line of therapy of 6, the ORR in the ITT population was 21.6%, with an ORR of 35.1% in the skin and 37.8% in the blood. It was very encouraging to see activity replicated in the larger phase II trial in these late line patients. A favorable safety profile was also seen. We look forward to further interactions with regulators as we get the final data later this year. The lower half of the slide summarizes the preliminary cohort 2 and 3 data in mycosis fungoides presented at EORTC in September of last year.

In this data presentation in the KIR3DL2 expressing cohort, we were encouraged to see that in these late line patients with a median of four prior treatments, lacutamab demonstrated a 28.6% ORR and six responses. We are particularly encouraged by the responses in the skin where we saw 57.1% ORR and with 12 responses. A reminder that skin response is an important response in this skin predominant disease. As many of you know, a clarification of the guidelines for CTCL have been released this year. We will be issuing more guidance on our strategy based on these criteria. In addition, we continue to engage with the FDA as per our FDA Fast Track designation. On slide eight, I would like to update you on monalizumab.

To remind you, monalizumab is an anti-NKG2A, which acts upon the checkpoint pathway to potentiate NK cell activation that we have licensed to AstraZeneca for oncology. On this slide, you can see an overview of the late-stage development plan for monalizumab in lung cancer. Based on the AstraZeneca-sponsored Phase II COAST data, AstraZeneca commenced PACIFIC-9, a Phase III trial evaluating the combinations of either monalizumab or oleclumab plus durvalumab in the unresectable Stage 3 non-small cell lung cancer setting, in patients who have not progressed after concurrent radiation therapy. For Phase II COAST study, the three arms evaluated the combinations of durvalumab plus monalizumab and durvalumab plus oleclumab, AstraZeneca's anti-CD73.

As published in the Journal of Clinical Oncology by AstraZeneca, after a median follow-up of 11.5 months, the results of an interim analysis showed a hazard ratio of 0.42 for durvalumab plus monalizumab versus durvalumab alone. The results also showed an increase in the primary endpoint of confirmed ORR for durvalumab plus monalizumab over durvalumab alone of 36% versus 18% respectively. The AstraZeneca-sponsored NEOCOAST-2 study is also underway in an earlier lung cancer setting, evaluating monalizumab and durvalumab with chemo in neoadjuvant non-small cell lung cancer patients. We look forward to updates from these studies from AstraZeneca at the upcoming ASCO annual meeting. I will now hand over to Yannis to cover our ANKET platform.

Yannis Morel (Executive VP of Product Portfolio and Strategy)

Thank you, Jayson. On slide nine, I wanted to highlight our proprietary NK cell engager platform that we call ANKET. ANKET standing for Antibody-based NK cell Engager Therapeutics. ANKET is a versatile fit-for-purpose technology made of various building blocks that is creating an entirely new class of multispecific engager to induce synthetic immunity against cancer. This technology platform, which is leveraging our scientific expertise in the NK cell space, will be an engine for our pipeline, creating value via a series of drug candidates addressing multiple tumor targets. The backbone of the ANKET-

Operator (participant)

Please stand by. A short technical difficulty and we'll just connect them back in. Thank you for standing by. This will now commence.

Yannis Morel (Executive VP of Product Portfolio and Strategy)

Sorry for the interruption. The backbone of the ANKET® platform is based on the unique engagement of the activating NK cell receptor, NKp46 and CD16 on NK cells, which allows for optimal harnessing of the NK cell effector function, which can be further increased by the addition of an IL-2 variant to induce NK cell proliferation. On slide 10, I wanted to share our enthusiasm for this platform. As you can see, our pipeline of ANKET® molecule is significantly growing, with Sanofi having now licensed 3 molecules and having an option on 2 other undisclosed targets. Our most advanced proprietary ANKET®, IPH6501, which is targeting CD20, is heading towards an IND this year. We have proprietary preclinical programs against multiple targets.

On the right panel, you can see the detailed mechanism of action of the ANKET molecules, which we have recently published in a couple of articles in high impact journals. Our Nature Biotechnology paper, published in January this year, describes a joint work with Sanofi on the CD123 NK cell engager, IPH6101 or SAR443579. SAR'579 is co-engaging NKp46 and 16 on NK cells and therefore triggers potent antigen-dependent killing of AML tumors as well as production of key cytokines for the antitumor response. Without inducing systemic cytokine release, which is dose limiting for most T cell engagers. We have shown that in our Cell Reports Medicine paper that the incorporation of an IL-2 variant into an ANKET induce a potential NK cell proliferation within the tumor microenvironment, increasing therefore the number of antitumor effector cells.

On slide 11, you can see an overview of the IPH6101 ANKET program, also named SAR'579. Preclinical studies demonstrate antitumor activity in mice, but most importantly, efficacy against patient primary tumors. They also showed good PK/PD and safety in non-human primates. In addition, one key advantage of the ANKET technology is shown on the graph here. As compared to a T cell engager against the same target here in red, SAR'579 in blue does not induce systemic cytokine release, which is a very common side effect for the T cell engager, suggesting a potentially better safety for the NK engager as well as allowing for potential higher dosing.

SAR'579 enter into phase I in December 2021 based on this rationale. We look forward to the presentation by Sanofi at the next month at ASCO as the SAR'579 phase I has been selected for an oral presentation. On slide 13, you will see the highlights on our recent Takeda deal we signed late last. We entered into an agreement whereby Takeda gained exclusive rights to a panel of selected antibodies against an undisclosed target to develop antibody drug conjugates with a primary focus in celiac disease, which is outside of our oncology focus. The terms of the agreement included a $5 million upfront and up to $500 million and up to $410 million in milestone and royalties on net sales.

The deal further demonstrates our antibody engineering expertise and its applicability to antibody drug conjugate development, as well as our ability to monetize pipeline assets in therapeutic areas outside of our area of expertise. Now, I will now hand over to Mondher for a summary.

Mondher Mahjoubi (CEO)

Thank you, Yannis. As you can see on slide 14, we are working diligently to execute across all our strategic pillars and believe that we are laying the foundation to drive near and long-term value. Looking at our clinical program, we expect to achieve a number of milestones over the next two years. As you heard from Jayson, our phase II TELLOMAK study for lacutamab continues to progress with final data due at the end of this year. In addition, we look forward to initial peripheral T-cell lymphoma data later in the year. In parallel, we continue to develop the NK cell engager technology platform further, reinforced by our partner Sanofi, and we are very encouraged by the preclinical results from our next generation NK cell engagers and progress in the clinic. Yeah.

I'm not sure where we disconnected, so I'm gonna probably go to slide 15, where you can see the upcoming abstract selected for the ASCO Annual Meeting. We look forward to 4 updates from our early ANKET with the first clinical data on IPH6101 to be shared by Sanofi. While AstraZeneca will provide progress on the 2 ongoing clinical trials with monalizumab in early stage non-small cell lung cancer. Let's move to the conclusion slide. On slide 16, as you can tell, we continue to our exciting journey at Innate. We look to build our business to create value for patients and stakeholders. In summary, we have positioned Innate Pharma for the future with our strategy and made meaningful progress across all three strategic pillars.

With our R&D engine and antibody engineering expertise, our science is producing more candidates to progress to the clinic. Some we are developing alone, and some are partnered. We have a focus on our NK engager platform, ANKET, as well as ADC. In parallel, our late-stage portfolio continues to advance as we look to maximize the late-stage portfolio assets of lacutamab and monalizumab. Our partnership strategy continues to evolve, with the recent Takeda deal adding to those of AstraZeneca and Sanofi. Finally, we have carefully managed our resources so we can continue a sustainable business to invest and progress in our pipeline. I'm very pleased that we continue to have a strong cash position with a runway into mid-2025. Collectively, we are driving value across our business and ultimately advancing our goal to deliver innovative medicine to patients. We look forward to keeping you updated on our progress.

That concludes our prepared remarks. We'll now open the call to questions.

Operator (participant)

Operator, do we have any questions? As a reminder, I would like to remind everyone in order to ask a question, press star one on your telephone keypad. Your first question comes from the line of Yigal Nochomovitz of Citi. Your line is open.

Ashok Kumar (SVP)

Hi, team. This is Ashok Kumar on for Yigal. Thanks for taking my questions. You alluded to some regulatory discussions you have planned later this year on Sézary syndrome. I'm just wondering if you can give us a sense of when those might happen and what the scope of those discussions might be. Thanks.

Mondher Mahjoubi (CEO)

Thank you. Jason, I hope you heard the question. It's about the regulatory strategy for lacutamab. You're on mute.

Joyson Karakunnel (Executive VP and Chief Medical Officer)

[audio distortion]

Mondher Mahjoubi (CEO)

Yes.

Joyson Karakunnel (Executive VP and Chief Medical Officer)

Okay. Yeah. I think I'm still on mute. Sorry. Thanks for the question, and thank you, [kumar]. From a regulatory standpoint, we are continuing to talk with the FDA based on FDA Fast Track designation. Those conversations are ongoing at this point, and we're trying to best proceed in alignment with the FDA to be able to, for our late-stage development for lacutamab.

Mondher Mahjoubi (CEO)

Thank you, Jason.

Ashok Kumar (SVP)

Okay.

Mondher Mahjoubi (CEO)

Thank you for the question. Do you have another one?

Ashok Kumar (SVP)

Yes, please. Okay. I'll ask one more then. Congrats on the recently signed Takeda deal. I'm just wondering if you can comment at all on the sort of rationale for using an ADC in a disease like celiac. I think we tend to think of ADCs as very intensive therapies, life-saving treatments. Whereas, for something like celiac, I tend to think of it as a more manageable disease with something like diet. I'm wondering if you can help us put that into context a little more. Thanks.

Mondher Mahjoubi (CEO)

Thank you. I'm not sure we're gonna help you that much. First of all, as you know, we are not experts in the field of inflammatory and chronic disease like celiac disease. Per the agreement with our partner, Takeda, we did not disclose any information on the target. Unfortunately, I cannot provide more granularity on the rationale of this deal and why. Nevertheless, Takeda has been invested in this field for quite some time, and they are of course expert in this development. I would refer to them to provide more details on this deal.

Ashok Kumar (SVP)

Okay.

Mondher Mahjoubi (CEO)

Hope you understand.

Ashok Kumar (SVP)

Thanks very much.

Mondher Mahjoubi (CEO)

You're welcome.

Operator (participant)

Your next question comes from the line of Daina Graybosch from SVB Securities. Your line is open.

Daina Graybosch (Senior Managing Director, Biotechnology, and Immuno-Oncology)

Hi, guys. Thank you for the question. I wonder if you could give us any context for the upcoming oral presentation of the CD123 ANKET at ASCO. In particular, you know, how many patients we're looking at? Is it PK/PD efficacy? If you can't give us any of those details, which I understand you may not, given it's partnered to Sanofi, what kind of data points you think is particularly important in this very first in-human data coming out for your ANKET platform, that would be validating for the overall platform?

Mondher Mahjoubi (CEO)

Absolutely. Thank you, Dana. Very important question. I wish we could have the opportunity to provide more details. This is a Sanofi phase I. No other info was disclosed or is disclosed at this time. You know that the abstract, the content will be disclosed on May the 25th. Presentation is scheduled for June 2nd. What I can say is this is a phase I trial that started back in December 2021. Of course, it's essentially in AML, but also in MDS and also some form of ALL. You can certainly have an idea of the patient population and the number of patients that you can expect from a dose escalation phase I. That's, that's all I can say at this point in time.

Sorry for not disclosing more because it's not in our hands.

Daina Graybosch (Senior Managing Director, Biotechnology, and Immuno-Oncology)

That's okay. I understand. How about just from an ANKET platform, what type of data you think would be validating? I guess I mean, like, are there particular PD biomarkers that you think are important for the platform for all the programs or certain PK markers in addition to efficacy?

Mondher Mahjoubi (CEO)

Absolutely. Yeah, certainly. Maybe I'm gonna hand over to Yannis to provide a little bit more color on this second question.

Yannis Morel (Executive VP of Product Portfolio and Strategy)

Hi, Dana. I think one important thing that we would like to see and that's why we'll be like you, really looking forward to see the abstract on the 25th and as well as the presentation is to see whether the claim that we are making based on the preclinical observation that we have made, translate into a clinical observation as well. Especially in preclinical, as I mentioned, we see a antitumor activity with in preclinical models. A direct efficacy without the need for additional NK cells.

Also most importantly is this lack of systemic cytokine release, which allow the dosing of the molecule at a, at a dose that is more in the microgram per kilogram range rather than the microgram per kilogram, which is the typical range for T-cell engagers.

Daina Graybosch (Senior Managing Director, Biotechnology, and Immuno-Oncology)

Great.

Mondher Mahjoubi (CEO)

Thank you, Yannis. Thank you, Dana. Do you have another question? Okay. Thank you.

Operator (participant)

Your next question comes from the line of Swayampakula Ramakanth from H.C. Wainwright. Your line is open.

Swayampakula Ramakanth (Managing Director and Senior Healthcare Analyst)

Thank you. This is RK from H.C. Wainwright & Co. Good afternoon, Mondher and team. Talking about the ANKET platform, in terms of IPH6501, the CD20 target, targeted ANKET, what sort of additional work you need to do to get to the IND? Also, you know, in terms of initiating the clinical trial, you know, can you give us a little bit more color as to the timing of that?

Mondher Mahjoubi (CEO)

Yeah. Thank you, RK. Thank you for the question. It gives me, of course, the opportunity to update everyone on IPH6501 or tetra-specific ANKET that is targeting CD20. As we said, IND filing is planned for this year. We are working diligently and the start of the phase I is planned in 2023. That's what I can say.

We are really actively working into executing the regulatory strategy and get the final go from the FDA for this phase I, which as you would anticipate is targeting CD20 disease and is a classic dose escalation phase first, and then the dose expansion part of it is coming next.

Swayampakula Ramakanth (Managing Director and Senior Healthcare Analyst)

Thank you for that. On lacutamab, in terms of the PTCL data that's expected later this year from the two studies, what sort of data should we expect? You know, what do you think is meaningful for you folks to see so that you can take this to the next stage of development?

Mondher Mahjoubi (CEO)

Sure. another important question. Joyson, did you hear the question about PTCL and, actually, expectation and what would be meaningful from a clinical standpoint?

Joyson Karakunnel (Executive VP and Chief Medical Officer)

Sure. Yes, I did, and thank you for that question. With PTCL, I mean, at this point we are enrolling the monotherapy as well as the combination with the gemcitabine and valproic acid. And that data, as you mentioned, is going to be at the end of this year, we will be disclosing data. I think when we look at what is meaningful, PTCL is a very aggressive disorder and very high unmet need with extremely low incidence. And today there is no really strongly established standard of care in relapsed refractory. It is very complicated to at least have a comparison drug in this relapsed refractory cohort.

With that being said, you know, most of the response rates can range anywhere from, with the different agents that we've seen, can range anywhere from, 25% upwards to, 40%.

Mondher Mahjoubi (CEO)

Thank you. Yes. Thank-- RK. Thank you. Thank you, Joyson and Mondher. Talk to you folks soon.

Swayampakula Ramakanth (Managing Director and Senior Healthcare Analyst)

Thank you. Bye.

Operator (participant)

The next question comes from the line of Justine Telliez of Kepler Cheuvreux. Your line is open.

Justine Telliez (Equity Research Analyst)

Thank you. Hi, everyone. Just two questions on the financial side, please. First, just for modeling purpose, how long will last the recognition of the two last up fronts received after the agreements with Sanofi and Takeda? Second, what is the expected evolution of the cash burn over the coming year, taking into account the cash burn of the Q1? Thank you.

Mondher Mahjoubi (CEO)

Absolutely. Thank you, Justine. I'm gonna hand over to Frederic, who will address the two questions. Maybe start with the cash burn.

Frédéric Lombard (SVP and CFO)

Yeah. With regards to the cash burn, we communicated that we will have a run away into mid 2025. We ended Q1 as expected. There is no change versus what has been communicated. With regards to your first question, we do not disclose the exact detail of the deal and how we progress and when the milestones are coming up, obviously.

Justine Telliez (Equity Research Analyst)

Okay. Thank you.

Mondher Mahjoubi (CEO)

thank you, Justine. Okay. Operator.

Operator (participant)

Before we proceed on to the next question, just a reminder, if you would like to ask a question today, please press star one on your telephone keypad. Your next question comes from the line of Liisa Bayko from Evercore. Your line is open.

Liisa Bayko (Managing Director)

Hi. Thanks for taking our question. This is Jayme on for Liisa. My first question is on monalizumab. For the PACIFIC-9 study, should we also expect a futility analysis for the study? My second question is on ADC. Will you consider developing any ADC in-house? Thanks.

Mondher Mahjoubi (CEO)

Thank you. Two great question. I'm gonna probably hand over to Jason. For the first one, any futility analysis planned for the PACIFIC-9 trial, Jason?

Joyson Karakunnel (Executive VP and Chief Medical Officer)

At this point, at least as the benefit is not disclosed a futility analysis.

Mondher Mahjoubi (CEO)

Thank you. The ADC, do we have an ADC strategy beyond what we have communicated on the Takeda deal?

Frédéric Lombard (SVP and CFO)

Yeah, actually, our antibody generic platform is generating several candidates and some of them, depending on the targets, are useful for an NK cell engager approach. Some of the others, depending on the target, but also depending on the properties of the antibody, are more suitable for ADCs. That's really something that we are contemplating for the moment.

Liisa Bayko (Managing Director)

Got it. Thank you.

Mondher Mahjoubi (CEO)

Thank you. Thank you. Okay, first of all, everyone, sorry for this technical issues and problems that we had during this call. Let me conclude this Q1 results by reminding everyone three key takeaways. As you can see, we are consistent, and we stay focused on our strategic priorities, which are advanced lacutamab, and we are getting close. Maximizing the ANKET platform, not only with, you know, the deal we signed end of last year with Sanofi, but now that we have clinical data coming around the corner. Finally, continue to build strategic partnership in oncology, but also outside oncology. I think the deal we announced with Takeda is a, the perfect example with that. Thank you very much.

Stay tuned for the important readouts that we have from our proprietary and partnered portfolio, which I expect as I said, over the next two years. Finally, strong financial position. We continue to be well-funded into mid 2025. Thank you. Have a good day.

Operator (participant)

This concludes today's conference call. Enjoy the rest of your day. You may now disconnect.
