Laurent Levy, Co-founder and Chief Executive Officer, Nanobiotix: Thank you, Joanne, and thank you, everyone. Good morning, good afternoon. Really happy to be here with you today to share our 2025 year and to give you a bit of perspective of what’s going to happen in the next 12 to 18 months. Today we’re gonna go over different aspects of things, how we’ve been moving the company for the past year and also give some financial highlights and then open for Q&A session. I think we’ve had a very rich 2025. We’ve been able to do many things during this year. First of all, start moving forward in a good way, the collaboration we have with Johnson & Johnson, and start showing the potential of this first product along with the potential of this deal in terms of future revenue for Nanobiotix.

While doing so, we’ve been also pivoting the company toward the new platform, which has been a big effort from the team, and I would like to thank them all for that. While doing those operational things in parallel, we’ve been able to really improve our cash visibility into 2028, and this beyond the timing of some of the expected milestones that should come from the collaboration with J&J. All together, we’ve had a rich year, and we’re pleased to share that with you. Now we’re going to go in some more details to give you a bit of insight. Before getting there, we’d just like to remind few things about the philosophy with which we are developing things at Nanobiotix. As you can see here, we mentioned delivering first-in-class directly. I think definitely we are doing more than this.

We are creating new class of drugs. That’s what we have done for the Radioenhancer, for the Nanoprimer, and also for the last platform, Oocuity. That’s really our philosophy. We don’t want to do what other biotechs are doing, not because it’s bad, because we think there are enough people working on the same target with the same technology. We really want to bring something deep and different to help millions of patients. That’s what we’re trying to do and we continue to do. Our strategy is simple and in line with what we told you last year. First of all is to continue to push and help J&J to address one of the potentially largest untapped market in oncology. That’s through our first product, radioenhancer, that have been licensed to Johnson & Johnson.

Beyond this product, we’re really pushing hard on new platforms, starting with the Curadigm platform, which we think is going to disrupt part of how we think about drug development. We have been starting to make good progress in that regard this year. Obviously, we will come back to that in more detail. Let’s focus first on NBTXR3 or JNJ-1900. What do we mean by addressing one of the largest untapped market in oncology? Well, I think for that, we still need to look at patients. When patients are diagnosed with cancer, the vast majority of them have a local disease. It’s more than 70% of patients having a local disease at diagnosis. Our industry in general is more focused on late-stage treatment of patients when they get metastatic or have received several lines of treatment.

If you think about it, if you want to have a big impact for those patients, it will be much better, if possible, to treat them at the beginning of their disease and try to eradicate the tumor when it’s still at a local stage. That’s exactly what we are trying to achieve with NBTXR3. For that, we’re working with radiation therapy, which is one of the largest treatments used in oncology. More than 60% of all cancer patients are getting radiation, and we have a product that we licensed to J&J that fits this existing market with almost no competition. You can see on this slide, we have a very large pipeline linked to this product that have been developing across many tumor.

Technically, that’s just a few examples of what could be done with this product because there are many, many other patients getting radiation in different oncology indications. But let’s try to look at where is the value here. What are the next key points of inflection. And how are we going to bring that to next steps. 2025, we’ve been publishing additional data in different cancer types. On top of the already established proof of concept in soft tissue sarcoma, the first data in head and neck cancer, we’ve been able to continue to show that this product could be widely applicable in oncology. Through 2025, we’ve been publishing data on head and neck cancer by talking here about the recurrent metastatic patients, also pancreatic cancer, esophageal cancer, melanoma cancer, and lung cancer.

All those data have been showing not only that you could use safely NBTXR3 in different indications, but also start to show some potential indication of efficacy for those different indications. Altogether, some consistency in the way you administer the product, but more importantly, in the way this product could amplify the radiation therapy and potentially bring new benefits and additional benefit to patients. Let’s focus on the two key developments. As you know, we’ve been transferring to Johnson & Johnson last year the ongoing phase III in head and neck cancer. That’s a very important trial as a phase III and could lead, if positive, to first approval and first market activity around NBTXR3. This trial is progressing well. J&J now has the full operation on this, and also, the financial aspect of this trial is taken care of by J&J.

We still expect to get the first readout of this trial the first half of next year. You may have noticed that on the top of this phase III, J&J has also started a phase I-B in another population of head and neck. Meaning patients getting radiation plus cisplatin. If you think about head and neck cancer, with those two trials, you’re technically capturing all the patients frontline that have a locally advanced tumor and that receive radiation and that cannot go to surgery. Technically, if you exclude, sorry, the few patients that have metastasis at diagnosis, with those two trials, you could capture the vast majority of head and neck cancer patients first line treatment with the highest unmet medical need.

That’s a very important pathway and could, if positive, establish NBTXR3 as a key player in the whole head and neck cancer treatment. Now, there is another trial which is equally important and potentially even more important. We’re talking about here the first lung cancer trial that J&J is running. The name of this trial is CONVERGE. It’s a randomized phase II trial in unresectable stage III non-small cell lung cancer. This trial is important for many reasons. First of all, as you may have seen, lung cancer is a very important aspect of the strategy of J&J in oncology. It’s also, as you know, a gigantic market, if not the biggest market, with breast cancer.

Here, starting with this trial, assuming that the data are positive, what we feel at Nanobiotix is that it could be a trigger for Johnson & Johnson to start expanding the development. If we just stick to lung cancer, that’s already a gigantic market per se. Here we’re talking about stage three, but it could expand into some other indication in lung cancer. Maybe as we did not have the occasion to talk about the data that have been generated, the first part of this data, let’s have a small focus on that. As I mentioned, we’re talking here about patients that have a locally advanced unresectable stage three lung cancer, and their treatment of reference is radiation plus chemo, followed by consolidation with durvalumab.

As you can see, if you look left and right of this box, many other patients in lung cancer would receive radiation therapy frontline treatment, which could be at some point an expansion of the use of this product, assuming that this trial reads positive. What’s the design of the trial? There’s two part in it. First, a safety leading with very few patients, and then, what we call a proof of concept with a randomized part of the trial where we compare the standard of care, chemoradiation with durvalumab, versus the same plus the product with two different dose. This is randomized one-to-one to one. Total should have 120 patients. Johnson & Johnson published that they should expect the readout of the randomized part beginning of 2027.

The data that have been presented this week are about the safety lead-in. There’s a lot of caveat around that. It’s a small number of patients, but nevertheless, we can start looking at what we observed here. We’ve been first showing a good safety profile with no serious adverse events linked to the treatment or the procedure, and a feasibility of injection in every patient. What has been observed is a good first rate of response that we could see as we’ve seen five out of seven patients responding. Equally importantly, we get 100% disease control, meaning that all those patients will go or went to durvalumab. Which is not the case if you look at the details of PACIFIC trial.

Many patients have been excluded post radiation chemo for different reasons, including progression, post radiation and chemo, which we did not observe so far in this clinical trial. Altogether, what we can say, it’s a first readout, encouraging, and we can’t wait to see the next steps of this safety lead-in or the final data that should come, as we mentioned, beginning of 2027. We can say we’ve been progressing a lot with this collaboration. Now that we have transferred the phase III to J&J, they are running most of the operation. We’re still running and finishing the Study 1100 trial that has completed in terms of recruitment. Now there is some follow-up of patient, and we will continue to deliver some data in that regard.

The collaboration with MD Anderson Cancer Center is still ongoing, with many trials that have been completed in terms of recruitment last year. We’re gonna see data this year, and we may open to new trials with MD Anderson Cancer Center. Maybe let’s take time to talk a little about our new platform, Curadigm. Here, we’re still talking about nanophysics. We’re still talking about nanoparticle, but with a different perspective, with different particle, with different potential benefit to the patient. Just as a reminder for those that are new on the call, as I see many, Curadigm is about trying to help many of the innovations we see in the biotech and the pharma arena. You can notice that most of the new innovation coming out is people are building more and more complex objects.

We can talk about oncolytic virus, RNA-based therapy, in vivo CAR-T, cell therapies, and all the subjects, because being complex, at some point, when you try to inject them IV, the liver will play a role of filter and will capture a big part of them, if not all in certain cases. For many of those innovation, it’s very hard to have access to the entire body with a normal IV route. Rather than doing what our industry is usually doing, which is let’s try to tweak this subject to make it more efficient and try to escape the liver while delivering at the right place, while delivering the payload and get the good transfection, for example. You’re building a lot of compromise in one object. With the Curadigm technology, we decided to build what we call a nano primer, a second object.

This Nanoprimer is injected prior to the second product, and this Nanoprimer has been specifically designed to transiently get into the liver and get it occupied for a certain amount of time. While the liver is busy, when you inject the second product, then it is much less captured by the liver and can have access to many other organs of the body. What you could do with this approach is improving pharmacokinetics of a product, allowing when it’s not possible to escape the liver, reducing liver toxicity, or combination of all this. There are many, many opportunities and many, many applications we could do with this technology. Now a big part of the team is focused on the development of it.

What we’ve been doing lately is really continuing pushing, meaning filing for four new patents application to continue to build our supremacy with this technology. We also have presented positive new in vivo preclinical combination with different type of combination. More importantly, we are moving forward toward the IND, and we’ve started the CMC activity with the start of the GMP manufacturing and also the preclinical studies allowing to file for an IND. While doing that the internal program at Nano, we’ve been extending a lot our external reach out. We have now more than 20 MTAs that we’ve been signing with pharma or biotech, where they have taken our product and they are testing it with one of their product to either improving the pharmacokinetic of this product or reducing the liver toxicity.

We’ve done that with many different technologies for different therapeutic areas like oncology, rare disease, CNS disorder. It’s moving quite well. Then we think, expect in a not-too-distant future to start transforming some of those MTAs into deals. Globally, the way we see the value of this platform and the three pillars that we are using to push it is first, continue to build and protect, the technology while building an internal pipeline. We want to have our fully own product to be developed up to a certain stage while we are building or planning of deals with different partner, pharma and biotech.

Of course, because of all this, we need to prioritize and build the right infrastructure to be able to build, to manufacture, and to provide this product to many partners and to our internal pipeline. Things are moving well, and we expect to get a bit more data and new data on this platform coming before the end of the summer. Just of note, last year, we’ve been entering a new index on the Euronext market, which is the SBF 120, and that’s an index that covers the 120 largest French-listed companies by market cap, liquidity. It does give us a bit more institutional visibility, and we’ve seen through that some of the new investors coming on top of specialized biotech investors that have entered our stock last year.

I’m gonna take this to give the mic to Bart to talk about the financial part of this presentation.

Bart Van Rhijn, Chief Financial and Business Officer, Nanobiotix: Thank you, Laurent. Good morning, good afternoon, everyone, and thank you for joining us today. Over the past year, we’ve materially strengthened the company’s financial foundation, positioning us to advance to upcoming value inflection points with greater resilience and strategic flexibility. This progress was supported by two strategic initiatives that meaningfully reshaped our capital requirements and hence our long-term operating flexibility. First, we amended our global licensing agreement with Janssen in a way that materially improves our financial profile. Under the revised terms, we have removed the vast majority of our funding obligations for the phase III NANORAY-312 study, while retaining significant upside through milestone payments that could total hundreds of millions EUR over the next 24-36 months. This amendment materially enhances capital efficiency, improves cash flow visibility, and better aligns the partnership structure with our long-term strategic priorities.

Second, we strengthened our balance sheet through the securing of a non-dilutive royalty financing with Healthcare Royalty Partners for up to $71 million. This transaction provides incremental capital while avoiding shareholder dilution, extends our projected cash runway into early 2028, excluding potential milestone inflows. Taken together the strategic initiatives that I just outlined enhance our financial flexibility, reduce near-term funding requirements, and position the company to sustainably advance its pipeline while maintaining a disciplined approach to capital allocation and long-term value creation. Turning to the next slide, just a brief overview of the deal we announced back in October. We’re extremely pleased to have partnered with Healthcare Royalty Partners on this transaction, bringing up to $71 million of non-dilutive capital into the company.

We selected HealthCare Royalty Partners following a comprehensive evaluation of financing alternatives, and given their deep sector experience and expertise, long-term investment outlook, and strong record of supporting innovative biotech companies, to partner with them. We believe that this partnership reflects the high degree of alignment around the long-term potential of JNJ-1900 and our broader strategic objectives. Critically, this royalty structure ensures that our partner’s return is directly linked to the success of our lead program, which aligns incentives while avoiding repayment obligations beyond the nominal value of the bonds. Moreover, this is a construct that is capped from a time and amount perspective, and therefore a capital-efficient way to finance the company beyond anticipated value inflection points to ensure we maximize the value for our shareholders.

This financing not only ensures we are funded through those critical inflection points, but validates the commercial potential of JNJ-1900 and supports our continued progress toward long-term sustainability and profitability. Moving over to our full year financial highlights. For the full year 2025, we recognized positive revenue of EUR 32.6 million compared to negative EUR 7.2 million for the year ended 2024. As a reminder, the negative revenue recorded in 2024 was primarily driven by a one-time recognition of the net liability to Janssen following the transfer of the sponsorship of the NANORAY-312 study. The positive revenue recognized in 2025 reflects a one-time accounting impact of EUR 21.8 million associated with the amendment to a licensing agreement that we executed in March 2025.

This amendment, as Laurent alluded to earlier, eliminated the vast majority of the company’s development cost obligations related to the NANORAY-312 study. This technical accounting effect related to the transfer of sponsorship and the cancellation of current and future study-related costs resulted in a corresponding impact on our reported top line, which is non-recurring. Said differently, as these changes in 2024 and 2025 are considered purchase price adjustments from an accounting point of view, these results flow through the revenue line in our profit and loss account. Let us turn to R&D expenses. These include clinical and manufacturing expenses related to the development of JNJ-1900 and pre-clinical pipeline activities, and totaled EUR 23.1 million for the 12-month period ended December 31, 2025. Which compares to EUR 40.5 million for the 12 months ended December 31, 2024.

As previously discussed, the significant year-over-year decrease of approximately 43% was primarily driven by the removal of development costs associated with the NANORAY-312 study following the transfer of sponsorship to Janssen. This transition resulted in the elimination of related clinical and operational expenditures previously borne by the company. More broadly, R&D spending during the period reflects continued prioritization of capital-efficient development across our clinical and pre-clinical programs, while maintaining investment in key manufacturing and pipeline activities supporting the long-term advancement of our auto platforms that Laurent just spoke to. Selling general and administrative expense for the 12-month period ended December 31, 2025 were flat to slightly down year over year at EUR 20.4 million compared to EUR 20.5 million, reflecting continued expense control.

Net loss attributable to shareholders was EUR 24 million or EUR 0.50 per share for the twelve-month period ended December 31, 2025, reflecting a year-over-year decrease of 65%. The decrease was primarily attributable to one-off non-cash positive revenue recognition accounting impact, together with a meaningful decrease in R&D expense resulting from the removal of the funding obligation for the NANORAY-312 study. This compares to a net loss of EUR 68.1 million or EUR 1.44 per share recorded for the same period last year. As we turn to cash and cash equivalents, as of December 31, 2025, that amounted to EUR 52.8 million compared to EUR 49.7 million as of December 31, 2024.

Based on the current operating plan and financial projections, Nanobiotix anticipates that the cash and cash equivalents of EUR 52.8 million as of December 31, 2025 will fund its operations into early 2028, assuming the receipt of the remaining $21 million from Healthcare Royalty Partners, expected in Q4 of 2026. To conclude, we remain focused on disciplined execution as we advance to key clinical and strategic milestones. We will continue to prioritize prudent capital allocation, operational efficiency, and balance sheet resiliency, and believe the foundation we have built positions us well for the periods ahead as we work to deliver long-term value for our stakeholders. Thank you. Now I would like to turn the call back to Laurent.

Laurent Levy, Co-founder and Chief Executive Officer, Nanobiotix: Thank you, Bart. Just in a nutshell, what’s coming for the 12-18 months in front of us, we will continue to push with our new platform, Curadigm, and we’ll continue to deliver new data and also visibility on how we’re gonna transform that into business. On top of that, the NBTXR3 or JNJ-1900 development is still key in our development, as should be the critical next step for value creation as we expect to get the result of the phase III in first half of 2027 and the result of the phase II in lung cancer in early 2027. Beside this year, we’re gonna deliver 4 different results of clinical trial, which 3 of them have been completed, so you’ll be able to see the final data for this.

The key takeaway for today, if we think about 2025 and what’s coming, is the changes, partnership, and the development of NBTXR3 is moving in the right direction with amplification of the development through multiple trials. We’ve continued to show that potential use of NBTXR3 across different indication, which reinforcing the potential value of this, product. As mentioned, we’ve continued the Curadigm development, a new class of drug that we intend to bring, to life. As Bart just mentioned, we’re getting in a good financial position as our cash visibility is going into 2028 beyond key milestone in head and neck and lung and potentially other milestone. As you have just seen, we have multiple near-term data readout that could continue to show, assuming it’s positive, that NBTXR3 could really, improve life of millions of patients. Thank you very much for your attention.

Now we’re going to open the call for questions.

Heidi, Conference Call Operator: Thank you. As a reminder, to ask a question, you will need to press star one one on your telephone and wait for your name to be announced. To withdraw your question, please press star one one again. We will take our first question. Your first question comes from the line of Tara Bancroft from TD Cowen. Please go ahead. Your line is open.

Bart Van Rhijn, Chief Financial and Business Officer, Nanobiotix2: Hi. Good morning or good afternoon for you guys. My question is about, you know, the lung data that you guys showed from CONVERGE yesterday that were really interesting, even if only in the first 7 patients. We were hoping you could give us some context for how you benchmarked that to the 45%-50% ORR. We ask because PACIFIC seems to be the best comp here, where ORR was actually around 30%, so just curious to hear your thoughts on that. Then on follow-up, when were these assessments taken that were in the poster, and how does that length of follow-up so far play into your level of confidence in the data that could potentially improving even further in part two? Thanks so much.

Laurent Levy, Co-founder and Chief Executive Officer, Nanobiotix: Thank you, Tara. Well, I think there are a few papers or historical controls we could look at as comparator for that. As a context, we’re using the PACIFIC regimen in this trial and patients getting radiation plus chemo, and if they do not progress, then they go to durvalumab. If you look at the PACIFIC paper, they start with 983 patients that receive radiation plus chemo, and out of that, only 70% will be randomized two-to-one in the direction of durvalumab, one with placebo. There is in the evaluation of the response rate in the PACIFIC paper, something telling 48% of response. But that excludes the 30% patients that have been not treated after that with durvalumab. That’s the response rate from there after radio chemo.

If you look at the response rate post durvalumab, then it’s going down, but it’s going down slower than the placebo arm. Here you’ll find the 27% response that you probably mentioned. Again, this 27% response is excluding the patients that have been frontline excluded from the trial before randomization. Altogether, if we take 40%-50%, that’s what we can find in some other paper as what radiation plus chemo is doing for those patients and close to what they find as an optimization in the PACIFIC regimen. I think that’s just the first part. The most important part is how this evolves over time. What we see in PACIFIC, some patients do not get duva, 30%, and then the rate is going down over time.

I think if R3 can provide a real local control, then we should see something different happening versus what you can observe with durvalumab. This will be answered a bit later and potentially definitely answered when we will see the results of the phase II, beginning of next year.

Bart Van Rhijn, Chief Financial and Business Officer, Nanobiotix2: Great. Thanks.

Laurent Levy, Co-founder and Chief Executive Officer, Nanobiotix: Thank you, Tara.

Heidi, Conference Call Operator: Thank you. We will take our next question. Your next question comes from the line of Clémence Thiers from Stifel. Please go ahead. Your line is open.

Clémence Thiers, Analyst, Stifel: Thank you. Thank you for the presentation. Just to come back to the CONVERGE study. Full data will be in early 2027. Is there any chance you or J&J could file based on the study, or do you have to run a phase III afterwards? That’s the first question.

Laurent Levy, Co-founder and Chief Executive Officer, Nanobiotix: Hi, Clémence. Thank you for the question. Well, first of all, we can talk to our partner. Now J&J is running the CONVERGE trial and has the license for the product, so that will be their decision. I think it’s a bit early to talk about that. That may be a question we could ask when we see the data coming from the phase II. If the data are excellent, everything is open. Again, that would be a J&J’s decision to move that direction or to do a proper phase III after that.

Clémence Thiers, Analyst, Stifel: Okay. Thank you.

Laurent Levy, Co-founder and Chief Executive Officer, Nanobiotix: We think all the best.

Clémence Thiers, Analyst, Stifel: Yeah. That was worth a shot. The second question, so in 2026, we’ll have all those additional data sets from your IO study and the MD Anderson studies. Are those the last ones in the sense that will you be after that at the stage where you or again J&J decide whether you move forward with it or not?

Laurent Levy, Co-founder and Chief Executive Officer, Nanobiotix: Yeah. I think some of those trials have been completed, like, the melanoma cancer trial, the lung re-radiation and the last one, esophageal cancer. Just to know that we are now looking with MD Anderson at opening some potential new trial to explore new avenues. That’s something that will come a bit later. Obviously, out of all those trials, we got a lot of signs of safety, feasibility, potential good efficacy for the product. Now it’s within the hands of J&J, but also discussing with us about potential next step. Nothing that we can say at this stage. I have one mention to do, is to maybe take a particular look at the MD Anderson cancer trial about lung re-radiation.

This trial, the recruitment has been completed last year, and we’ll see the final data this year on more patients with more follow-up. I think this trial is very important because it’s not like the same population that is treated in CONVERGE, but to a certain extent could be seen as a surrogate of what we could observe in CONVERGE. We will pay particular attention to this trial, but also, we’ll bring that to you, to your attention.

Clémence Thiers, Analyst, Stifel: Okay. Thank you very much.

Laurent Levy, Co-founder and Chief Executive Officer, Nanobiotix: Thank you, Clémence.

Clémence Thiers, Analyst, Stifel: Thank you.

Heidi, Conference Call Operator: Thank you. We will take our next question. Your next question comes from the line of Jonathan Chang from Leerink Partners. Please go ahead. Your line is open.

Albert Abstinus, Analyst, Leerink Partners: Good morning, good afternoon. This is Albert Abstinus on for Jonathan Chang. Congrats on all the progress, and thanks for taking my question. My question also reflects on the CONVERGE data. How do we extrapolate these results to your other ongoing trials and potential indications? Secondly, if I may, how do you foresee JNJ-1900 will be positioned within the landscape of non-small cell lung cancer treatment paradigm. Thank you.

Laurent Levy, Co-founder and Chief Executive Officer, Nanobiotix: Thank you. Well, I think lung stage III cancer, like locally advanced head and neck cancer and other tumors are different because they’re coming and they are in different organ. They all share something, is that if you can improve the local control and have a strong rate of response and CR, then you can deeply change the PFS and overall survival. What our product does is improving the absorption of energy, killing more cells. We know when you have a local disease, killing more cells may lead to more control. That’s the basic thesis that led us to start developing NBTXR3 and going into frontline treatment when patients have a local disease. That’s also what Janssen is going after. If we think about the two trials in head and neck and this trial in lung cancer.

For us, it does establish the strong power of having local control transforming into benefit for patients. Starting from this point, then we could anticipate or imagine the diffusion of this product across different populations that are also getting radiation. It’s always crucial to demonstrate that this works when local control plays the key role in the survival and quality of life of patients. That’s how we will extrapolate the results of CONVERGE, but also that’s what we started to do with the randomized data coming from soft tissue sarcoma, which was a similar situation, even though this is very different. That’s a good start to any tumor type. If we think about how to extrapolate to other indications, that could be a path. Now for lung cancer, there are many patients receiving radiation beyond lung stage III.

It’s around 77% of lung cancer patients getting radiation. Not to mention that small cell lung cancer is also another indication where radiation is key. We could imagine, but again, that will be change this decision to spread this product across different lung subpopulation.

Albert Abstinus, Analyst, Leerink Partners: Thank you.

Laurent Levy, Co-founder and Chief Executive Officer, Nanobiotix: Thank you.

Heidi, Conference Call Operator: Thank you. We will take our next question, and the question comes from the line of Swayampakula Ramakanth from H.C. Wainwright. Please go ahead. Your line is open.

Bart Van Rhijn, Chief Financial and Business Officer, Nanobiotix1: Thank you. This is RK from H.C. Wainwright. Good afternoon, Laurent, Bart, and Gwen. I also have a couple of quick questions on CONVERGE. So, you know, in your mind, do you see J&J, when they’re spending time on both NANORAY-312 and CONVERGE, do you see them sourcing equal time for both of these projects? And additionally, do you have any data from your partner regarding abscopal effect in the lung? Because injecting into lung lesions are potentially technically challenging. So how do you and your partners see this being a successful therapeutic modality in the lung?

Laurent Levy, Co-founder and Chief Executive Officer, Nanobiotix: Thanks. Well, first of all, about the bandwidth, or the investment in lung versus head and neck. I think a phase III is always bigger than the phase II, and in that case, that’s a very big phase III versus the CONVERGE trial. So there’s much more people working on one than the other, which is normal given the size of things. The attention is equally important from our perspective and what we can observe. Obviously, as I mentioned previously, the lung is a very important trial for J&J and also for us, because if it does work, that’s really opening a big market for JNJ-1900 or NBTXR3. Let’s say that what we observe is they’re pushing on all fronts to make sure that all this could happen. Now on the abscopal effect, I think that’s a big question.

That’s an effect we already observed in melanoma patient, head and neck patient, some of the lung patient, when they have met with or without primary tumor. When we do inject one lesion and irradiate that lesion. We see a distant effect in the non-irradiated, non-injected lesion. That’s something we start observing in many different clinical situation that will be very useful to understand and to investigate when we think about metastatic patient. For the vast majority of patients getting radiation, they have no met. They have a local or local regional disease. Here, local control is much more important than any potential immune response. If we can provide it through local injection of the particle plus the radiation, that could be a win.

In the case of loco-regional, when some of the lymph node could be involved, then we’ve seen in different trials now that we are able to inject lymph node on the top of the primary tumor, which could add also an additional immune response. RK, if we just step back a minute. I think this abscopal effect or the possibility to trigger an immune response is really critical for MET, as I mentioned. Also if you think about loco-regional disease where radiation plays a role, usually the loco-regional area is irradiated. Which is not in favor of having an immune response because the x-ray, as we know and have seen, could kill some of the activity of the immune system.

Here the local control brought by physical treatment like radiation with the addition of JNJ-1900 is where we should play and where we should try to win.

Bart Van Rhijn, Chief Financial and Business Officer, Nanobiotix1: Thank you for that. One quick question on Curadigm. You did present some preclinical data previously. Now thinking, going forward, you know, since you also have a collab, you know, MTAs with multiple parties, are you planning to initiate an IND from the internal pipeline or do you expect some of these external collaboration partners to file first? How should we think about that program going forward?

Laurent Levy, Co-founder and Chief Executive Officer, Nanobiotix: We are pushing both because we think building our internal pipeline will have a first proof of concept of this product into human, and that’s what the team is working on. Not only by manufacturing the product and starting pre-IND studies, but also designing the first proof of concept we want to bring to life. If we think about it, as soon as we have established the safety and feasibility of this product into human, that’s also opening many more combination possibilities with other products that are already into clinical development. That will not only push forward our pipeline, but also will open many other opportunity for collaboration and licensing out.

Bart Van Rhijn, Chief Financial and Business Officer, Nanobiotix1: Thank you. Thanks for taking all my questions.

Laurent Levy, Co-founder and Chief Executive Officer, Nanobiotix: Thanks, RK.

Heidi, Conference Call Operator: Thank you. We will take our next question. Your question comes from the line of Chiara Montironi from Van Lanschot Kempen. Please go ahead. Your line is open.

Bart Van Rhijn, Chief Financial and Business Officer, Nanobiotix0: Hi, this is Sandrine on for Chiara. Thank you for taking our question. So for the J&J driven phase II trial on lung, do you expect that J&J will report an interim before the readout in early 2027? If they do, what do you think they will most likely disclose the ORR or, the post durvalumab from, part one?

Laurent Levy, Co-founder and Chief Executive Officer, Nanobiotix: Thank you for the question. Yes, that’s true. There are multiple readouts in this trial. Different range of response depending on timing, PD-1, and also potential measurements as exploratory for other more systemic endpoints like PFS and OS. Now we can talk for J&J. What we can say is what has been said previously, which is the readout of the phase II, beginning of 2027. In between, who knows.

Bart Van Rhijn, Chief Financial and Business Officer, Nanobiotix3: Okay. Thank you. On the MD Anderson lung reirradiation trial. You said you expected to read out in 2027. Is there any possibility you can narrow down on the timing?

Laurent Levy, Co-founder and Chief Executive Officer, Nanobiotix: We filed for different abstract. If first one accepted, that should be around December.

Bart Van Rhijn, Chief Financial and Business Officer, Nanobiotix3: Okay. Thank you so much for taking the question.

Laurent Levy, Co-founder and Chief Executive Officer, Nanobiotix: You’re welcome. Thank you for the question.

Heidi, Conference Call Operator: Thank you. We will take our next question, and the question comes from the line of David Dai from UBS. Please go ahead. Your line is open.

David Dai, Analyst, UBS: Great. Yeah, thanks for taking my questions and, congrats on the progress. A couple questions from me as well. Just on the CONVERGE trial. You know, so just thinking about the JNJ-1900, how do you think this, you know, early post-CCRT response seen over SAW from Part 1 could translate into durable local control and PFS benefit in Part 2? I have a follow-up after that.

Laurent Levy, Co-founder and Chief Executive Officer, Nanobiotix: Well, I mean that’s depend on how durable will be the response. But that’s generally what we have observed in other clinical trial with different disease. When you start getting radiation, you usually get the optimal efficacy of radiation a few months after the end of the last session. Here patients are going directly, I mean, rapidly into durvalumab. The good point is that first of all of them went to durvalumab, which is not the case when you look at the overall population. Now we need to wait the next set of data to conclude on that. If we believe of what we have seen previously in other trial, we should expect a much greater local control.

Now we’ll see how this potentially impact a more systemic aspect of things for the patient.

David Dai, Analyst, UBS: Got it. Okay. Thanks, Laurent. Just on the next follow-up. Just on the part one study here, would we expect another follow-up of this data from the part one and also for the part two, which we’re expecting, you know, to have some data in early 2027. Could you just help us understand a little more around what’s the sort of expected data readout? Would it be OR or should we look at PFS as well?

Laurent Levy, Co-founder and Chief Executive Officer, Nanobiotix: I don’t know. What we know is that all this that you mentioned are endpoint of the trials, but we don’t know what J&J is going to communicate yet.

David Dai, Analyst, UBS: Thank you so much for taking my questions.

Laurent Levy, Co-founder and Chief Executive Officer, Nanobiotix: Thank you, David.

Heidi, Conference Call Operator: Thank you. Your next question comes from the line of Michael Schmidt from Guggenheim. Please go ahead. Your line is open.

Michael Schmidt, Analyst, Guggenheim: Hi guys. Thanks for taking my questions. I had a couple more on the CONVERGE data from yesterday. Obviously, very interesting. Could you confirm whether part two of that study is enrolling or are still patients being added to part one, so the safety lead in component of the trial?

Laurent Levy, Co-founder and Chief Executive Officer, Nanobiotix: Yeah. Part one has been completed and the phase II part, randomized part is enrolling since last year.

Michael Schmidt, Analyst, Guggenheim: Okay. That makes sense. Yeah, just so you know the sort of next update in early 2027. Is your impression that this is sufficient for your partner to potentially make a phase III go decision? Or do you think more follow-up may be needed to look at things like, you know, DFS or maybe even OS to make that move into a large phase III trial?

Laurent Levy, Co-founder and Chief Executive Officer, Nanobiotix: That’s a very good question, Michael. I think overall, first of all, a response in those patient population, if you find a high rate of response, then you should get an impact and a correlation with PFS and OS. I think the number of CR globally also could be a surrogate of that as expected did show very little rate of CR, less than 1.7% in the post-Jevtana treatment. Globally, patient, if you look at the dynamic of the curve, they’re relapsing quite fast in Jevtana arm versus radio plus chemo. I think comparing all those data, we can say if you beat that bar then you move to phase III directly. You don’t need PFS. You don’t need OS.

I think that should be a mix of results linked to number of patients getting to Janssen, because usually 30% are not. Number of patients getting response, number of patients getting complete response, and then you can start following PFS and OS to see. A combination of all these or just few of them, depending on the magnitude, could be enough. At the end, that’s J&J’s decision to look at this and to take the path moving forward.

Michael Schmidt, Analyst, Guggenheim: Okay. Makes sense. Then another one. I know this may be, again, difficult to answer, but what is your sense how J&J may prioritize other indications beyond, head and neck and lung? For example, breast cancer is obviously a very big opportunity and prostate as well. To what degree do you think they’re incorporating data that’s sort of coming out of the ISTs that have been ongoing?

Laurent Levy, Co-founder and Chief Executive Officer, Nanobiotix: Well, that’s a tricky question we can’t answer. What we can say is, you can see the priorities of J&J in terms of indications like lung, bladder, head and neck, and so on. As you mentioned, breast cancer is not part of those priorities. Also we have all the trials we’ve been running or are still running with MD Anderson that could serve as a base for expansion. Even though we have a lot of discussion with J&J’s team about optionalities, there’s nothing we can say at this moment.

Michael Schmidt, Analyst, Guggenheim: Okay. We’ll keep our eyes out for any other updates there. Thank you for the update. Really appreciate it.

Laurent Levy, Co-founder and Chief Executive Officer, Nanobiotix: Thank you, Michael.

Heidi, Conference Call Operator: Thank you. Once again, if you wish to ask a question, please press star one one on your telephone. We will take our next question, and the question comes from the line of Kelly Shi from Jefferies. Please go ahead. Your line is open.

Kelly Shi, Analyst, Jefferies: Hi there. Thank you for taking my question. Just two from me, please. Actually just on potential indication expansion on J&J’s part. I know there’s obviously not much you can comment on their behalf, but the indications that MDA is working on, is there scope for J&J to actually expand the RP program into those indications, so a pancreatic, esophageal, et cetera? That’s my first question. Then I can ask a follow-up after.

Laurent Levy, Co-founder and Chief Executive Officer, Nanobiotix: I’m sorry. I’m not sure I got. The question was can they or will they?

Kelly Shi, Analyst, Jefferies: As in, can they? Just, are they able to?

Laurent Levy, Co-founder and Chief Executive Officer, Nanobiotix: Okay. Yes, of course, they are able to. Obviously all the clinical trial we’ve been running serve really as a base for discussion with them. They can.

Kelly Shi, Analyst, Jefferies: Okay. That’s clear. Just actually on cash burn. Obviously R&D’s come down pretty sharply post the transfer to J&J. What’s the sort of steady state annual cash burn we should assume through to 2027?

Bart Van Rhijn, Chief Financial and Business Officer, Nanobiotix: Thank you for the question. We don’t provide specific forward-looking guidance to the individual years, and we refer to the cash runway that is in early 2028. We have a very disciplined approach to how we allocate capital. What you’ve been used to in the past few years, you should expect to continue to see from us. Maybe one high level comment is that as the NANORAY-312 costs have been transferred to our partner Janssen, we should expect to see development costs on the new platforms that Laurent Levy talked about.

Kelly Shi, Analyst, Jefferies: Sure. That’s really clear. Thank you so much.

Laurent Levy, Co-founder and Chief Executive Officer, Nanobiotix: Thank you.

Heidi, Conference Call Operator: Thank you. Your next question comes from the line of Clément Dastot from Portzamparc BNP Paribas. Please go ahead. Your line is open.

Clément Dastot, Analyst, Portzamparc BNP Paribas: Hi. Good morning, Laurent, Bart. Thank you for the presentation and for taking my questions. I have two. First, I was wondering how much R&D you spent in oncology in H2, and how much was allocated to Curadigm just in order to assess the shift. Secondly, regarding the mechanism of Curadigm, my understanding is that with the Nanoprimer, we will reduce the effective dose level, but at the same time we may also reduce the lethal dose. Could you please provide some insight into the relationship between these two dose, if the relationship is linear or not, and if this could lead to narrowing the span between these two dose due to the suspension of the liver clearance. Thank you.

Bart Van Rhijn, Chief Financial and Business Officer, Nanobiotix: Let me try to address the question on the R&D spend and how that is proportioned between our three new platforms. What I can share is that at this time, and this is relating to full year 2025, the spend on the Curadigm has been ramping and should be in the low single-digit millions EUR. Again, as we start to pivot and have pivoted meanwhile to these new platforms that spend will obviously increase. But for the past year, it was a smaller amount compared to the total R&D spend.

Clément Dastot, Analyst, Portzamparc BNP Paribas: All right. Okay.

Laurent Levy, Co-founder and Chief Executive Officer, Nanobiotix: Hi, Clément. To your second question about Curadigm, I think the answer is yes, there is a correlation, but will depend also on the need of the product. Let me try to get to that. What the Nanoprimer does is by occupying transiently the liver, it will allow a second product to circulate more freely. If this product had a strong accumulation in liver, but not much toxicity, what you’re going to play on is the ability for the second product to circulate more freely and to reach other target that will not be able to reach normally. But if this product had a high liver toxicity, which prevent him to be used at the right dose, then you will play more on the liver toxicity by preventing the accumulation while allowing some circulation of a therapeutic dose.

There’s always a correlation between the dose of the Nanoprimer and the quantity that you will avoid to be captured in the liver and the quantity that will be allowed to circulate. There is a link to that. Different product will request different outcome, and that’s where we’re gonna play A or B. Meaning more efficacy or less safety issue. In some cases, we can play on both.

Clément Dastot, Analyst, Portzamparc BNP Paribas: All right. Thank you.

Laurent Levy, Co-founder and Chief Executive Officer, Nanobiotix: Thank you, Clément.

Heidi, Conference Call Operator: Thank you. This concludes today’s question and answer session. I’ll now hand back for closing remarks.
