Roivant Sciences Q1 2027 Earnings Call Transcript

Key Takeaways

  • Positive Sentiment: Brepocitinib’s potential dermatomyositis launch remains on track for late September, with priority review completed and commercial, patient-support, and market-access teams prepared. Management expects a “slow and steady” rollout focused on building a broader franchise across multiple indications rather than maximizing early prescription volume.
  • Positive Sentiment: Roivant reported progress across its brepocitinib pipeline, including initiation of a Phase III cutaneous sarcoidosis study and strong enrollment in the lichen planopilaris program. Top-line data are expected in the second half of 2026 for brepocitinib in noninfectious uveitis and mosliciguat in PH-ILD, with additional cutaneous lupus data also anticipated.
  • Neutral Sentiment: The mosliciguat PH-ILD readout is expected to focus primarily on pulmonary vascular resistance, while management cautioned that the study is not powered to provide a definitive six-minute-walk result. Translating prior PAH data into PH-ILD remains a key program risk, particularly given differences in lung pathology and emphysema levels.
  • Positive Sentiment: Roivant received approximately $950 million from its Moderna settlement, with about $772 million flowing to Genevant and Arbutus, and continues separate litigation against Pfizer and BioNTech that could represent an additional $1.3 billion if successful. The company accelerated share repurchases, buying roughly $200 million of stock during the quarter and continuing to retire shares.
  • Positive Sentiment: Management highlighted a dense upcoming catalyst calendar, including further updates on difficult-to-treat rheumatoid arthritis and IMVT-1402, with Graves’ disease data expected in 2027. Roivant ended the quarter with nearly $4 billion in cash before the settlement proceeds, supporting continued investment in its pipeline and capital returns.

After the speaker's presentation, there will be a question and answer session. To ask a question during the session, you need to press star one and one on your telephone. Please be advised that today's call is being recorded. I would now like to hand the conference over to your first speaker today, Stephanie Lee. Thank you. Please go ahead.

Stephanie Lee Griffin
Stephanie Lee Griffin
COO at Roivant

Good morning, and thanks for joining today's call to review Roivant's financial results for the first quarter ended June 30, 2026. I'm Stephanie Lee with Roivant. Presenting today, we have Matt Gline, CEO of Roivant. For those dialing in via conference call, you can find the slides being presented today, as well as the press release announcing these updates on our IR website at www.investor.roivant.com. We'll also be providing the current slide numbers as we present to help you follow along. I'd like to remind you that we'll be making certain forward-looking statements during today's presentation. We strongly encourage you to review the information that we have filed with the SEC for more information regarding these forward-looking statements and related risks and uncertainties. With that, I'll turn it over to Matt.

Matt Gline
Matt Gline
CEO at Roivant

Thank you, Steph, and good morning, everybody, and thank you for joining. This is a little bit of a calm before the storm moment for us, a pretty quiet quarter, maybe not the most interesting of our earnings calls in recent memory. Nonetheless, a lot of great progress in the business. Certainly, we're expecting a jam-packed second half, as I'll get to in a moment. I'll be relatively brief in my remarks, then we'll go to Q&A. I just want to start on slide four. This is a slide we took from our own prior deck. This is from the investor day that we did in December of last year, this was a list of our priorities for the year. We're sitting here a little bit more than halfway through the year.

Matt Gline
Matt Gline
CEO at Roivant

Just wanted to highlight that it's gone well for us, that we feel really good about the setup. On slide five, looking across the list here, we've got brepocitinib expected to launch by the end of September. Obviously, we got priority review and our PDUFA date, as we said, is this quarter. We had great data from IMVT-1402 in the D2T RA study that we presented on our last quarterly call. Probably the most notable update for today, the top center of this slide, is that we've now enrolled patients in the phase III study in cutaneous sarcoidosis for brepocitinib, which follows on the positive results that we had in our phase II data, which I think we announced on our first quarterly call of this year, earlier in the calendar year.

Matt Gline
Matt Gline
CEO at Roivant

We've now received the initial payment from Moderna in the settlement, and the sort of second part of that, the Section 1498 part of that case is progressing as we filed international proceedings against Pfizer and BioNTech in that case. Finally, earlier this year, we added LPP as a fourth brepocitinib indication. As I'll remind people later today, that study is continuing to enroll really well. As I mentioned at the top of the call here on slide six, I'll just say this is a quiet quarter and this is a quiet day. I don't know exactly how the following statement could be true, but I think it is. The next 6-12 months are in many ways busier than the prior 6-12 months for us, and so we just have an enormous amount coming up.

Matt Gline
Matt Gline
CEO at Roivant

Starting, as I mentioned, with the upcoming potential brepocitinib launch in DM, which should happen imminently, assuming everything goes as we hope and expect it will with FDA. We've got top-line data in brepo from the NIU study, an indication that could easily be as large as dermatomyositis. That data is coming in the second half of this year. We also have top-line data coming shortly in the second half from mosli, the phase II study in PH-ILD. I know that's being closely watched and we're looking forward to getting that data and presenting it.

Matt Gline
Matt Gline
CEO at Roivant

We will provide further updates on the D2T RA program at Immunovant in the second half of this year, including hopefully a download on a conversation we hope to have with FDA about that program, as well as the results from the second part of the study and a little bit more about our plans going forward. Finally, probably the smallest of these, we're expecting top-line data from the PoC study in CLE also in the second half of this year. I'm looking forward to finding out what we've got there when that comes in as well. Just a jam-packed second half and even more coming in 2027 with the Graves' data and beyond. Just a lot in the here. I'll just hit a couple of highlights in terms of the pipeline updates in a little more detail here before, again, before we go on to Q&A.

Matt Gline
Matt Gline
CEO at Roivant

Starting on slide eight with a reminder, because it's been a few months since we've talked about it. The initiation of this cutaneous sarcoidosis phase III study is a pretty exciting event. It's a little bit ahead of schedule in terms of what we've been able to do here. This is a disease that we're just privileged to be able to work in here. It's a high morbidity, very difficult disease with a high urgency to treat. You can see on slide eight some of the photos we've shared before, but these are patients who are really sick and have very few treatment options. On slide nine, as a reminder of the data that we generated in our phase II study, we had set for ourselves a goal of a sort of five-point benefit on the CSAMI scale for clinical meaningfulness.

Matt Gline
Matt Gline
CEO at Roivant

In the study on the top left of this chart, we showed a greater than 20-point benefit compared to roughly nothing on placebo. Just a huge benefit to those patients in the phase II study, and really excited to carry that forward into the pivotal program. As a reminder on slide 10, we think this is a pretty decent-sized indication, again, with high unmet need, probably about 40,000 patients in the U.S., and reasonable overlap with some other organ systems, including optical sarcoidosis or eye sarcoidosis, where that overlaps with NIU.

Matt Gline
Matt Gline
CEO at Roivant

That is one of the types of NIU that we're studying, as well as pulmonary sarcoidosis, which is a big potential indication as well, and where we hope to be able to treat some of those patients via either their ocular sarcoidosis or CS. The phase III study that we've now begun, the design is laid out on slide 11. I know there were some questions after the phase II about what exactly this study would look like. It is designed to take all of the learnings from the phase II study that was successful. It is a 16-week study with the primary endpoint of CSAMI greater than or equal to 50% response rate.

Matt Gline
Matt Gline
CEO at Roivant

It's a 140-patient study across about 70 sites, 3:2 randomized with patients either on 45 milligrams of brepocitinib or placebo, and with a mandatory steroid taper going from week two to week eight down to zero, which is roughly consistent with what we did in the phase II, and generally consistent with what we think is appropriate for patients in this indication. That study, as I said, has already begun enrolling patients, and we expect top-line data in 2028, which just adds to the list of potential registrational indications for brepocitinib coming up. I'll reiterate on slide 12, the other ongoing registrational program is the brepocitinib study in lichen planopilaris, LPP, that we announced earlier this year. That study is enrolling, I'll say, extremely well. There's a lot of enthusiasm from physicians and patients for that.

Matt Gline
Matt Gline
CEO at Roivant

Speaks to the high unmet need on the indication, speaks to the quality of the work being done by Ben and the Priovant team. I'm looking forward to sharing more about that as soon as we've got it. That's also moving along nicely. Look, finally, I'm sure there will be questions about this in Q&A and lots of opportunity to talk about it, hopefully with a potential approval and beyond. Obviously, one of the major events in the near term here is the potential launch of repasitinib in dermatomyositis. Obviously, I think we're in a phenomenal position here in terms of what we've got and in terms of what we hope to be able to do.

Matt Gline
Matt Gline
CEO at Roivant

Starting with the quality of our clinical data, which as you know from the multiple times we've talked about it from the publications, including in The New England Journal and so on. Just phenomenal data, stats significant across all 10 endpoints, big clinical benefit, a lot of enthusiasm from the doc community. This is a really tough disease. A large addressable population, most of them on sort of polypharmacy, trying a lot of different things, and frankly, most of them still dissatisfied with the available treatments. We feel like we have an opportunity to do something big and different for this patient population. Our team has been out spending a lot of time with the physician and the patient communities on overall education.

Matt Gline
Matt Gline
CEO at Roivant

I think the enthusiasm for a new therapy is coming out loud and clear, including with all the academic presentations that have been done and so on. Commercial launches, there's not much to say today other than that it's on track. We're ready to launch on time, having received priority review. The sort of commercial and patient support teams are built out, trained, ready to deploy. We feel really great about the hires we've made there, really great about the organizations we've built there. We think we're doing this in a way that is both capitalizing on all of the learnings from successful launches at other companies in recent years and doing it in a Roivant, Priovant way.

Matt Gline
Matt Gline
CEO at Roivant

There's nobody in the world that'd be more excited to oversee this than the team we've got at Priovant with Ben and Daniel and others, I think we're going to be fully ready. Everything's on schedule. We'll have much more to say about that with the potential approval and after, but looking forward to it. I'll say one more thing about the commercial franchise overall of repasitinib on slide 14. We get a lot of enthusiastic questions from investors around pace of launch, and we've been pretty consistent that our answer to that question is sort of slow and steady is what we're looking to build there. I think there's a bunch of reasons for that. Obviously, some of them are DM is a new indication, and no one's launched a novel therapy basically ever, or at least a targeted therapy basically ever.

Matt Gline
Matt Gline
CEO at Roivant

It's just hard to know exactly what work will need to be done to get everyone comfortable and excited and on drug. Although I think we're fully prepared. Also, to me, it's because repasitinib is a lot more than just dermatomyositis. To me, what we're really doing here is not just trying to make that launch as fast as possible. We're trying to lay the groundwork for the overall opportunity, which goes beyond DM into first NIU and then CS and LPP with the data coming thereafter.

Matt Gline
Matt Gline
CEO at Roivant

I think as you think about that layering, to me, it is much less about what week one or month one or quarter one look like, and much more about making sure that the foundation around access, the foundation around patient support, the foundation around the institutional activities, the foundation around our communication with the scientific and physician community, and our communication with patients are all set up to deliver the maximum opportunity for brepocitinib across all of these indications. I think slow and steady isn't just about sort of guidance. Slow and steady is about the approach that we are taking with the program to make sure we have maximum reach across everything that we are doing there, including indications that we are excited about beyond the ones we have already announced. A lot to come, as I said, on track for that launch.

Matt Gline
Matt Gline
CEO at Roivant

You all hear the same thing we do, which is a ton of enthusiasm from the patients and physician community for new options in all of these indications and looking forward to sharing more when we know about it. Our guidance is going to continue to be slow and steady because that is what we think we are building. Final business update here is we got the upfront payment in the settlement with Moderna.

Matt Gline
Matt Gline
CEO at Roivant

That $950 million has come in, $770-ish million of it to Genevant and the rest to Arbutus. That is done. There will be progress in terms of return of capital, et cetera, of that via Arbutus and so on. Section 1498 sort of appellate ruling is that process is ongoing at the Federal Circuit. That would be another $1.3 billion if we got a favorable outcome there. We continue to advance our litigation against Pfizer and BioNTech.

Matt Gline
Matt Gline
CEO at Roivant

We filed three international lawsuits, notably in Canada and the UPC in July, just last month, and continue to progress that case as fast as we can. Not all of it in our control, but equally enthusiastic about the potential there in terms of what we could get. I will wrap up just with our usual financial update on slide 17. Look, I think overall, most importantly, we are spending in areas that we are excited to be spending. We are excited about all of our R&D programs, about $200 million of R&D expense for the quarter of just under $100 million of non-GAAP adjusted G&A, or $166 million of GAAP G&A expense. Cash just under $4 billion, and that is before the receipt of the $772 million. Notably, pretty significant share repurchase activity, about $200 million in the quarter, a bit more than that when you include March.

Matt Gline
Matt Gline
CEO at Roivant

What we did there was we accelerated our share repurchase program upon the announcement of the Moderna settlement, so that we could get those shares in and the shares that. As a reminder, the shares that we bought back kind of the first round of this, the 1.5 billion that we had bought back sort of up through mid last year, we bought back at around $10 a share. I think the average price at which we have been able to buy back stock since we kicked off the second round of this in earnest in March has been in the high $20s. Feeling good overall about retiring those shares and getting that capital back to shareholders. I am going to continue doing that according to our authorizations for now.

Matt Gline
Matt Gline
CEO at Roivant

All of it ahead of, on slide 19, a really rich catalyst calendar ahead with a lot coming. Looking forward to all of that with just an incredibly busy stretch ahead. On slide 20, again, a little bit incredulous for the people around Roivant who are doing all of this work or incredible for the people around Roivant who have to do this work. By the end of calendar 2028, we'll have had hopefully three or more commercial launches, nine or more clinical study readouts, four plus NDA or BLA filings, a number of proof of concept studies, just a ton coming up in the near term. With that, I'm going to wrap up my prepared remarks for the day. I will hand it back over to the operator for Q&A in just a moment.

Matt Gline
Matt Gline
CEO at Roivant

Thank you again for listening this morning. Looking forward to taking your questions.

Operator

Thank you.

Matt Gline
Matt Gline
CEO at Roivant

Operator, over to you.

Operator

Certainly. We will now begin the question and answer session. As a reminder, to ask a question, please press star one and one on your telephone. If you'd like to cancel your request, you can also press star one and one again. Our first question comes from the line of Brian Cheng of JPMorgan. Your line is open. Please go ahead.

Brian Cheng
Brian Cheng
Analyst at JPMorgan

Hey, guys. Good morning. Thanks for taking our questions. Just thinking through the DM launch, Matt, can you give us a quick sense of what metrics we could be receiving right out of the gate to help us better track the initial launch? Secondly, on PH-ILD, as we think about the baseline characteristics here in FOCUS, it seems that more patients are on nintedanib. We're curious if there's any implication in terms of the fibrosis versus emphysema ratio in the populations, and then further down the line, whether there's any implication towards the bar for success for both six-minute walk and also PVR. Thank you.

Matt Gline
Matt Gline
CEO at Roivant

Perfect. Thanks. I appreciate both questions. Look, on DM a thing I've gotten fond of saying as I've watched other companies with commercial launches is that you all don't deserve our guidance, which isn't quite fair. Look, I think other than sort of a slow and steady launch and obviously the sort of top-line metrics will be plainly visible in our financials each quarter, I don't know that we're going to provide a ton of detail in the early days. I think it's important for us mostly to spend our time focused on understanding those dynamics ourselves, getting out, talking to patients, talking to physicians, doing the work we need to do. We'll give a little more color on what that's going to look like on a call with potential approval, and then we'll start to flesh out the package that we share with each successive quarter.

Matt Gline
Matt Gline
CEO at Roivant

I don't have a lot to say right now about metrics. I'll say I think typical with these launches, I'm not sure a ton is going to be visible in the early days, just given how the commercial apparatus is set up for actual purposes. We'll provide more guidance on that as it gets closer and is here. On PH-ILD I guess first of all, we've obviously been watching for example the treprostinil data in IPF and trying to understand a little bit better what's been going on with these PH-ILD patients in treatment of PH-ILD for fibrosis and for lung disease.

Matt Gline
Matt Gline
CEO at Roivant

It's been a view of ours for a while that one of the things to look out for in treatment of PH-ILD with vasodilators is emphysema. The study was designed with care around the amount of emphysema allowed in the study overall, and that was an important part of the guiding philosophy of the study to make sure that we can serve the patient population broadly, but also while maximizing the potential benefit of the therapy. That was considered from the beginning. Those are, I think, things we're keeping an eye on. I know there is a vocal cohort that believes that treprostinil has antifibrotic benefit. I think our view is if you treat PH-ILD patients well for their pulmonary hypertension, you may well deliver a benefit overall on their lung disease.

Matt Gline
Matt Gline
CEO at Roivant

I think our view is probably that vasodilation is driving a lot of the activity there. We also have some evidence from non-clinical models of antifibrotic activity for mosliciguat. Overall, on six-minute walk and PVR, I'm sure I'll get versions of this question more today. I think it's consistent with what we said before. We're hoping to see a clear signal on PVR. We expect if the drug is at all active, we will. We don't expect to see very much with clarity on six-minute walk. The study's not powered for six-minute walk. It would be nice to see some separation, but I don't think that's essential for our sort of go, no-go decision from here. We'll know what we've got once we get a closer look at it, including the full balance of that data. Thanks, Brian.

Brian Cheng
Brian Cheng

Thank you, Matt.

Operator

Thank you for the good questions. Next question comes from the line of Dave Risinger from Leerink Partners. Your line is open. Please go ahead.

Dave Risinger
Dave Risinger
Analyst at Leerink Partners

Thanks very much, and thanks for all the updates, Matt. I have three questions. Rather than rattling them all off right now, maybe if it's okay, I'll go one by one. First, on mosli, you commented just now on six-minute walk distance. If you were to run a large trial, what type of six-minute walk distance would you be hoping for? I.e., what would be relevant to the clinicians and to the patients? That's my first question.

Matt Gline
Matt Gline
CEO at Roivant

Thanks, Dave. I think obviously we'll have a slightly better answer to these questions overall once we have a sense of what we saw in phase II. The truth is that PH-ILD patients are really sick. There are not a lot of options for these patients. As we saw in group 1 in PAH, when you have more treatment options, first of all, patients go on multiple options, multiple lines of therapy. Second of all, most importantly, the actual, not from a clinical trial perspective, but from a real-world evidence perspective, survival and mortality rates go down as new classes of drugs are introduced in PAH over time. I think it's less about a number on six-minute walk and more about having an approvable therapy. Remember, these are patients that are trying to walk to the car. They're trying to walk to the bathroom.

Matt Gline
Matt Gline
CEO at Roivant

They're trying to live their daily lives. I don't know that I think it's correct scientifically to describe a specific numerical bar that matters versus just being able to get a new therapy. Some of that's frankly because six-minute walk in clinical settings is an artifice that is complicated and noisy and a little bit difficult to translate into daily lives. Whereas if these drugs really effectively vasodilate and improve lung function and improve PVR, I think you wind up seeing a lot of benefit for these patients. I don't know that we're going to articulate or have a specific numerical bar versus a successful study. Obviously, we will be judged, especially by the investor community, based on competitor data, but I don't think we even need to be per se better than any other mechanism in order to have a big benefit to patients. Thanks, Dave.

Dave Risinger
Dave Risinger
Analyst at Leerink Partners

Great. That's very helpful. Regarding the forthcoming brepo DM launch, could you discuss the cadence of formulary reviews for rare disease drugs? I ask because for mass-market drugs, P&T committees often wait until six months after launch before putting drugs on formulary.

Matt Gline
Matt Gline
CEO at Roivant

Yes. Thanks. Look, I don't have a ton to say about that right now other than we're having all of the normal engagement with the payer community that you'd expect us to have at this stage. Also, I think this is a critical point about all of these launches, we are super focused on making sure that the physicians who want to write this drug and patients who want to get on this drug are going to have access. I think that's going to be really important for our engagement with the community for access generally. I think in terms of literal formulary, it's probably not so different. It's not like there's a separate committee for different kinds of diseases, but there's lots of medical exception procedures and other things that you can do to get patients covered.

Matt Gline
Matt Gline
CEO at Roivant

We have a whole team of people built out of Priovant that's dedicated to making sure whether the formulary work has happened yet, whether the P&T committee has happened yet, is not something that our patients and physicians have to spend a lot of time thinking about as they're deciding how to use the drug.

Dave Risinger
Dave Risinger
Analyst at Leerink Partners

Excellent. That's really helpful context. Then finally, beyond the list of programs on slide 19, could you remind us about pipeline and product opportunities for your portfolio, including specific products that you could announce initiation of new studies for over the next year or so?

Matt Gline
Matt Gline
CEO at Roivant

I think every single one of the programs that the world is aware of in our pipeline, as well as potentially ones that the world is not yet aware of in our pipeline, in all of those cases, we could announce new trials, new indications in the next year. I think every one of those are eligible, all of our molecules could be put into indications beyond the ones we've talked about. I think it's fair to say in each case, we have specific ideas of indications we're excited about. We've done active work and are, in fact, preparing to initiate programs to varying degrees, depending on how busy those teams are today versus next month or the month after, but real progress.

Matt Gline
Matt Gline
CEO at Roivant

I think the answer is we are actively working on that, all of our products are, as you called them, pipeline into products, and we're excited to share more indications as we start those studies.

Dave Risinger

Thank you for the questions. The next questions comes from the line of Samantha Semenkow from Citi. Please go ahead.

Samantha Semenkow
Samantha Semenkow
Analyst at Citi

Hi. Good morning. Thanks very much for taking the questions. I also have two, one on mosli, one on brepo. For mosli, I'm wondering if you could just talk about the translatability of PVR reductions in patients with PAH to those with the PH-ILD population that you enrolled in FOCUS. Are there any aspects of either disease that could influence the magnitude of PVR that you could see in the mosli data? I have a follow-up.

Matt Gline
Matt Gline
CEO at Roivant

Yeah. Thanks for the question. I appreciate it. I think the translation from PAH to PH-ILD is the fundamental question being answered by our study. The first unfortunate answer to that question is we're just going to have to see what we see. It is the risk of the program at some level that we find something. Again, the phase I data, including in PAH patients, looks very good on a PVR basis. One of the main "risks" of this program is that there's something, I would call it unexpected, in the PH-ILD translation. I use the word unexpected because I think scientifically it seems relatively straightforward that inhaled vasodilation is an effective mechanism in PH-ILD, we'll find out. The lungs of PH-ILD patients are different than the lungs of PAH patients.

Matt Gline
Matt Gline
CEO at Roivant

You might expect some difference in sort of the pharmacodynamics of the drug in those patients. Overall, it seems pretty clear that when you take an inhaled vasodilator in a PH-ILD patient, you get drug to the healthy lung tissue and it matters. That's what I'd say.

Samantha Semenkow
Samantha Semenkow
Analyst at Citi

Got it. Thank you. That's very helpful. Just on brepo and DM, in your conversations that you've been having with physicians for education, I'm wondering if you could just talk about the reception to brepo given the JAK class safety concerns. The safety profile on VALOR was quite favorable, from a class perspective, it would just be helpful to hear how the physicians are thinking about safety, particularly since DM patients already tend to have a higher underlying risk for cancer. Thanks very much.

Matt Gline
Matt Gline
CEO at Roivant

When we first in-licensed brepocitinib, we didn't exactly know what the reception to JAK inhibitors was going to be following the addition of black box warnings. Our whole view was to choose indications where the safety profile of JAKs was going to be much less of a focus. I think dermatomyositis is a poster child for this in that while JAK inhibitors are at this point extremely widely used in diseases with much less morbidity, many more alternative therapies. In dermatomyositis there's really no other options available, I don't think physicians therefore are going to be particularly focused on this question. Remember, these patients are often. First of all, I think you sort of alluded to the profile in the trial.

Matt Gline
Matt Gline
CEO at Roivant

Dermatomyositis patients are inherently at risk of many of these concerns, malignancies, cardiometabolic events, and treating them well makes them healthier and reduces those risks. Then on top of that, the therapies that they are currently on for dermatomyositis are things like high-dose steroids, which in themselves add meaningfully, in fact, in many cases, much worse than JAK inhibitors to those very same risks. Yeah, I think in general, physicians are not going to spend a lot of time worrying about this, especially when reminded of the inherent risks of steroids and immunosuppressants that they're on anyway. It's clear from our conversations with docs across different prescriber bases that they're just very comfortable using these agents, including prescriber bases, as we said, for patients with significantly less severe disease.

Matt Gline
Matt Gline
CEO at Roivant

As a reminder, we fully expect that our label is going to look like the labels for other JAK inhibitors, that it's going to have the black box warnings. It's going to talk about experience with JAK inhibitors and other indications. Like I said, I think docs expect that and I think are not going to be too concerned about it because these patients are, A, very sick, and B, on other drugs with, in many cases, significantly worse safety concerns.

Thank you for your questions. Our next questions will come from the line of Prakhar Agrawal from Cantor Fitzgerald. Your line is now open.

Prakhar Agrawal
Prakhar Agrawal
Analyst at Cantor Fitzgerald

Hi. Thank you so much for taking my questions and congrats on the continued execution. Maybe a couple of questions from my side as well. Firstly, on brepo and DM, could you remind us what percentage of DM patients are on off-label JAKs based on your latest primary or secondary research? Would you expect rapid switches from these patients who are on off-label JAKs to brepo? If not, why is that the case? Secondly, for brepo in NIU trial, what do you see as the biggest risk for phase III given the phase II was really strong? Is this geographic variation, which has been a key risk for this trial, which could drive some of the baseline variability that has been flagged as one of the risk factors by some of the KOL checks that we have done? Thank you. Really appreciate it.

Matt Gline
Matt Gline
CEO at Roivant

Great. Thank you. In terms of your first question on brepo and DM around who's on off-label JAKs and what does that look like? Look, I think first of all, there's just variability in physician practice, and some physicians use more JAKs and some physicians use less JAKs. That has more to do, I think, with the docs in many cases than with any specific subcategory of patient. I think what we've said publicly is a low single-digit % or mid-single-digit % of dermatomyositis patients have experience with these things. Some of the docs who are involved. Some of that's some docs don't use off-label drugs full stop.

Matt Gline
Matt Gline
CEO at Roivant

I think some of the docs who use off-label JAKs have said they expect to switch patients over and I hope they do and obviously we'll be working to help them where that's appropriate facilitate those switches. I think it's just going to be down to the preference and practice of each individual doc. I think one of the things that our team is finding in talking to physicians is that different docs have different sort of ideals in mind for who their sort of first patients might be, and I think it just varies based on the patient experience, the physician. Obviously we'll be able to have much more of these conversations pending a potential approval. I think medically we'll see a wide variety of different phenotypes. On NIU, what is the biggest risk in phase III?

Matt Gline
Matt Gline
CEO at Roivant

It feels funny to call placebo a risk in these trials. That's not quite exactly what I mean, but I think the variability in placebo response rates in immunology trials is significant. If you're asking me what keeps me up at night, it's that we don't know exactly what placebo response rates will be in that study. That just makes it hard to know exactly what the trial is going to look like on outcome. Obviously, the phase II data was quite compelling, and the level of drug activity seems good. I'm pretty optimistic about the study. This is biotech, so you can lose sleep over anything. Is geography a risk?

Matt Gline
Matt Gline
CEO at Roivant

I think there may be geographic variation, just as there is in many other indications, and some of that's literally driven by geography, and some of it's driven by physician practice, and some of it's just noise. I don't know that it's a risk in the sense that it's unanticipated or whatever. It's just a feature of running immunology studies. Overall, I think the team is doing a great job with the study, and I hope it's going to come out well. Thank you.

Hey, thank you for taking the question. I don't think this has been talked about yet, but for the brepo launch, can you maybe talk about a few launch analogs that you're assessing right now, either patient curve or market share curve? What are the historical products with the most resemblance to brepo in DM? Thank you.

Matt Gline
Matt Gline
CEO at Roivant

Well, thanks. It's a good question. The truth is there has never been a launch of a targeted therapy in dermatomyositis before. There is no good "analog" in the sense that you can point to lots of other launches of lots of other kinds. Some have been faster. Some have been slower. Some have been slow and steady. Some have been just like different versions of different things. I think it's hard to say. There have been successful products with all kinds of different launch phases. I think the short answer is I don't have a specific analog for another drug that we're watching as evidence of our own penetration. I think what we're really focused on here is the dermatomyositis opportunity itself, these docs, these patients.

Matt Gline

The benefit and the cost of being a pioneer in an indication is that you don't get to look at others. You have to chart your own course. I don't have an analog to point to. Thanks, Andy.

Hey, guys. Thank you for taking my questions. Just a quick one on difficult to treat RA. Could you maybe talk about the strategy there? Would you need one more study, two more studies? How are you thinking about that? What should be our expectations for the randomized withdrawal phase that we're going to get data on? Thank you.

Matt Gline
Matt Gline
CEO at Roivant

Thanks. Great question. On study designs, we're going to come back later this year with a full update on that program, and that includes we don't yet have the randomized withdrawal period data yet, so I can't speak to what's in it or how it will or will not inform strategy from here. I think at some level, the results of that study may inform whether it is usable or not as one of our pivotal studies, et cetera. I think we designed it to serve potentially as one of two, but obviously it's got to hit for that to work. As we said when we announced the data, the quality of the response rates in the open label period have set a somewhat higher bar for hitting a p-value on the randomized withdrawal section.

Matt Gline
Matt Gline
CEO at Roivant

I think we've got to sort of see all that, take in an aggregate look at the patient-level data, understand what's going on. We are planning for an FDA conversation this fall that will inform both the exact design of that study as well as help us answer those questions. I don't have a specific guidance to give on exactly what those studies are going to look like now because we don't know. I'll say the team's working on it hard. The data was obviously exciting. It has gotten noticed. We've got a lot of enthusiastic reception, including from the doc community on it. We're excited to finalize those plans and bring them back to you later this year. Thank you.

Thank you for the questions. Our next question comes from Yaron Werber from TD Cowen. Your line is now open.

Yaron Werber
Yaron Werber
Analyst at TD Cowen

Great. Thanks so much. I have a couple of questions. The first one with mosli, once you release the data this year, would you release both the mono and the combo data at the same time? Secondly, for CS, the trial design is super interesting and makes obviously a lot of sense. The primary endpoint is CSAMI more than a 50% response. Can you maybe translate the phase II data into the same context? Because I think the phase II looked at CSAMI over 10 points and the change from baseline. I'm just trying to get a sense of apples to apples, kind of what to expect. Thank you.

Matt Gline
Matt Gline
CEO at Roivant

Great. On mosli, I think the short answer to your question is we will not release the monotherapy data and the combo data at the same time because the combo study started much later and is enrolling now, whereas the monotherapy study obviously will read out pretty soon in the second half. I think the answer is they won't come out at the same time. We'll put out the combo data when we've got it. The combo study, remember, it's an open label study. The truth is I think a lot of the information that we could want will come out of the monotherapy study anyway, such that the combo study won't provide that much incremental.

Matt Gline
Matt Gline
CEO at Roivant

I think it was designed in part to give us really good Safety experience in the combination as well as a little bit of information about incremental efficacy, just so that we could get a sense for inclusion criteria and management in the phase III. I'm not sure it's going to be a super informative outcome. Yes. That's what I'll say on mosli. I think data are going to come at separate times. On CS, I don't have to give right now the exact delta, but I'll say we saw meaningfully higher rates of greater than 50% CSAMI in the treatment arm than in placebo. The delta was wide.

Matt Gline
Matt Gline
CEO at Roivant

I think in the press release that may have gone out around the initiation of the CS study, it all said well north of 50% of the patients in the treatment arm of the phase II had a CSAMI response rate of greater than 50% compared to, I think it was zero on placebo. It should be a good bar to set for us in terms of the endpoint. I don't know that we're going to replicate exactly what we saw in the phase II, but I think the point is it's well powered for probability of success given what we saw in the phase II.

Yaron Werber
Yaron Werber
Analyst at TD Cowen

Right. If I can maybe just sneak in the phase III NIU, do you have a sense, is the percent HUMIRA experience going to be the same as the phase II, given that the data looked pretty good overall? It must have been pretty good in that segment too. Thank you.

Matt Gline
Matt Gline
CEO at Roivant

I don't think we've said, thank you, what the percentage of patients in the phase III have HUMIRA experience. I don't have that number on the top of my head, so I'll have to check into it, but I think the answer is there's no reason to expect it to be very different than what we've seen. There are a meaningful number of HUMIRA-experienced patients in the phase III, which matters in terms of ability to go into all of those patients. I think the short answer to your question is I wouldn't expect it to be a major driver and I wouldn't expect anything markedly different about the patient population from the phase II. Thanks, Yaron.

Hey, good morning. Thanks so much for the updates and for taking our questions. On the IMVT-1402 difficult to treat RA program, I just wanted to clarify how you're approaching the disclosure in the second half of the year. Should we expect to see the part two randomized withdrawal data prior to your meeting with FDA? Are you planning to share the data and the regulatory feedback and next steps simultaneously? Then on Graves', just wanted to get your thoughts on the competitive landscape. Obviously, you're the first advanced therapy there with really stellar phase II data, and you'll have the first pivotal readout next year with IMVT-1402. There are a number of different approaches targeting various segments of the Graves' patient population. Just wondering if you could comment on the competitive landscape.

Thomas Smith
Thomas Smith

As you see some of the approaches some of these competitors are taking with respect to the patient population, wondering how you're thinking about potential future studies for IMVT-1402 in Graves'. Thanks so much.

Matt Gline
Matt Gline
CEO at Roivant

Yeah, perfect. Those are both really great questions. On the first one, I think what we said when we put the data out still holds. I think my dream, our dream for the second half of this year is that we can come back with everything tied as nicely into a bow as possible, which is to say the period two data, the FDA conversation, maybe some further analysis of patient experience through both periods in the RA study, all shared at the same time. Obviously, until we have the part two data in hand, we can't sort of specifically know whether there's anything in there that requires earlier disclosure. In general, I think the answer is our hope and expectation would be to give a fulsome update later this year on everything all at once for D2T RA.

Matt Gline
Matt Gline
CEO at Roivant

On Graves', look, I think first of all, I cannot say enough times that discussion of competition in Graves' disease among therapeutic categories is just misplaced in the sense that you've got so many patients with unmet need that have had no option. The last time a novel therapy was developed in Graves' disease was like the 1950s or 1960s. There's so many patients who have need of novel therapy that it's not about outrunning the bear. It's not about beating some specific competitor. It's about changing doc behavior in an indication that badly needs new options. IMVT-1402 will have been studied in lots of patients. It's a safe and well-tolerated drug. Graves' is going to have room for lots of mechanisms and lots of products.

Matt Gline
Matt Gline
CEO at Roivant

Among the other mechanisms, some will have specific either safety liabilities or they'll mimic a thyroidectomy and they'll require treatment with SYNTHROID or there's just lots of different approaches and those drugs may be appropriate for later line patients or a different subset of the patient population. Over time, I'm sure that segmenting will occur. First of all, we're going to be first out in the marketplace there long before anybody else. We're going to get to have some influence over the treatment paradigms and also just get an option out to patients and physicians before some of those other choices are available. Second of all, I think it's mostly about building the market, not about any specific alternative and so on.

Matt Gline
Matt Gline
CEO at Roivant

Look, we're tremendously excited to be in our position in Graves' to be first to be able to offer hopefully a new option here. The only other thing I will say is you learn a lot running these studies. You learn a lot engaging with this physician community. I do think there is nuance to the patient population and I think there is nuance to the prescriber behavior. I think there's a lot of heterogeneity in terms of how these patients are managed around the world and around the U.S. I think one of the things that we're going to be able to do is to take advantage of those learnings in future studies, in these studies, in commercial prep. I think that will be a big benefit to us in being in the first place here. Thank you

Shannon Duffy

Hi, this is Shannon on for Yas Rahimi. Congrats on the great quarter. Maybe just one more from us about clarity with the readout in second half 2026. Could you give us just maybe what you might be thinking about narrowing guidance if you expect to do that, then sort of how you're thinking about the bar for success? Then timing post-data, would you expect to file an sNDA, and sort of what would be the cadence on that? Thanks.

Matt Gline
Matt Gline
CEO at Roivant

Thanks. Look, I doubt that we're going to provide more specific timing guidance at this point than we have. We announced, I think, when the study was fully enrolled, I think we're just going to read the study out when it's done and we have the data clean. The truth is, NIU is another one of these diseases where there's a lot of unmet need. HUMIRA leaves a lot of room on the table, and frankly, a lot of patients aren't even getting it. I think the truth is that the bar for success is successful studies that would support registration, and I think if we get that, we will have a big opportunity to help lots of patients who need it. I don't think there's a numerical bar.

Matt Gline
Matt Gline
CEO at Roivant

Obviously, better data is better, and the more we look like our phase II, the happier I'll be about that. Our phase II was really great data. Overall, I think as long as we have a successful clinical trial, a successful outcome, we're going to get what we need, and we have a lot of patients we can reach. I don't want to put Ben on the spot right now on exactly when that sNDA goes in, but we got the DM 1 in nice and quickly. I know the team is enthusiastic for NIU as an indication, so if that study's positive, you got to believe that team's going to be working really quickly to get that sNDA in as fast as possible.

Hey, thanks for taking the questions. Two quick ones from me. I guess for the proof of concept readout in CLE, there's a few parts to that study, so just remind me of what we'll be getting in that initial release this year. Then for the initial launch in dermatomyositis, remind me how many clinics you're targeting and the concentration of patients at those clinics. Thanks.

Matt Gline
Matt Gline
CEO at Roivant

Yeah, thanks. On CLE, again, I think we've said this before in other settings, it bears mentioning. I think CLE is an interesting indication. This is a small study. It's really a fact-finding proof of concept study. We've been watching the competitive landscape in CLE closely. There's a lot of other exciting therapies in development as well. Early data from a couple of patients that we have dosed was encouraging. We're really sort of overall just looking to understand what our treatment benefit looks like, how we could conceptually stack up in the future treatment landscape, and I think that will all be super informative to what we do from here and whether we go forward. I think the primary, as a reminder, is 12 weeks 600 versus placebo. Then in period two, all patients go out 600 at 52 weeks.

Matt Gline
Matt Gline
CEO at Roivant

The thing that we'll be reporting first is that 12 weeks for 600 versus placebo. That's what we'll see. Obviously a bunch of other data beyond just the specific primary endpoint. On the DM launch, I'm not going to share today exactly what our sort of targeting strategy is, but as a reminder, there's about 200 myositis referral centers that treat approximately half of the U.S. patient population. Obviously those clinics are, those docs, those centers are an important part of the overall picture, but there are other important physicians as well. I think Ben and the team have done a really great job overall engaging with the physician community. I'm excited about what we've done there, excited about the sort of medical publication strategy. Obviously, The New England Journal publication was a great outcome.

For the questions. We will now take the last questions from Alex Thompson of Stifel. Please go ahead.

Alex Thompson
Alex Thompson
Analyst at Stifel

Hey, great. Thanks for taking our question. Maybe two more on IMVT-1402. Going back to the questions around placebo responses. How are you thinking about managing placebo response in the Graves' studies, particularly in the backdrop of ATD down titration and the potential for waxing and waning of disease in that context over longer periods of time? Secondly, what's your current thinking on sort of where IMVT-1402 could fit within MG and CIDP as that landscape continues to evolve? Thanks.

Matt Gline
Matt Gline
CEO at Roivant

Yeah. Thank you. Great questions. Appreciate it. Look, on Graves', I think the short answer to this question is if you set the bar high enough on the endpoints, these are just not patients who are spontaneously remitting. If you're looking at patients who are getting to proper thyroid hormone levels and off ATDs, I think the simple truth is placebo should be pretty manageable here without saying much more about exactly how the AT titration works and so on, and different of the studies being run by different companies are taking slightly different approaches there. I'm not going to say too much about exactly what we're up to. Overall, I think this is something that is likely manageable.

Matt Gline
Matt Gline
CEO at Roivant

I think as far as MG and CIDP are concerned, I'll say First of all, it's pretty rare that you have a great drug where you can run a clinical trial and be just very confident that the trial is going to work. FcRns have been studied many times in MG at this point. IMVT-1402 really should work in MG. The data that we generated in bato, although I know there was plenty of debate over the deeper is better question, we think showed a real treatment benefit, especially on things like MSD and sort of clinical remission that other FcRNs, in our view, have not been quite as compelling on. I think we have an opportunity to deliver really great data, and I think that data will translate to adoption. I'll say two other things.

Matt Gline
Matt Gline
CEO at Roivant

One is that the MG market has just shown itself to be extremely large. There's room for lots of different classes, there's room for multiple FcRNs, there's a little bit of cycling going on, there's differences in dosing paradigm and so on. I think no matter what share we take, even a relatively modest share of a market that size is a big opportunity. I think argenx has done a really great job establishing that market, establishing themselves in that market, becoming the drug of choice that people reach to for a next-generation therapy. I think they may very well remain the class leader there. I think we will find lots of operating room around them with hopefully incremental, meaningful benefit to patients beyond what they can deliver and just with another option, with different route of administration and so on.

Matt Gline
Matt Gline
CEO at Roivant

I think in MG, we'll be out there. I think we'll have a big opportunity just given the size of the overall market exactly what our share is and where we fit in will depend on the clinical data that we generate in the study. CIDP, my one comment is, I think the Well, I'll make at the end on other indications. I think in CIDP, class leadership has been less concretely established at this point. It's a more recent launch. I think there's probably a little bit more room for improvement on treatment paradigm. I think what we showed with bato in the CIDP study was pretty encouraging. I hope we're able to do something similar with IMVT-1402. I think there will be a lot of enthusiasm if we can for our role there.

Matt Gline
Matt Gline
CEO at Roivant

I think we have an opportunity to be a major driver in that market. Overall, I think the level of success that argenx has had with things like MG and CIDP makes me tremendously excited about Graves and about [Digoxin] and the other indications where we are first, in that the first-mover advantage that argenx has been able to develop in their indications are significant, and I expect to build a similar moat for ourselves. I think ultimately these docs are going to be sensitive to clinical data, focused on clinical data. I think if our data is phenomenal, we'll be able to lead in every indication where we have that kind of data. Great docs are going to follow the quality of the evidence.
