Thank you, Steph, and thank you, everybody, for listening this morning. It's great to be back. It's -- I was talking to the team this morning saying it feels like a slightly anti-connected call because we were obviously just together last week to talk about the really exciting data from the chronic period of our RVT3101 study. But actually, an enormous amount has happened for us, both in this fiscal year generally as well as specifically in recent quarters. So looking forward to providing updates on those topics. We'll talk a little bit about where we are through the course of our year. We'll give some great updates on the progress that we're making with the ongoing launch of VTAMA as well as a reminder of our atopic dermatitis results. We'll do a quick refresh of the data we put out last week on RG311, A quick update on our FcRn program, a financial update, and then we'll turn the line over to Q&A.
Starting on Slide 5. Just kind of as a reminder or a level setting, look, we're really proud of the continued progress that we've made here. We celebrated this quarter with a dooring, the 10th consecutive positive Phase III study that we have run. That's the most recent 10 studies that we've run have been successful. We now have 6 products that we've gotten approved by FDA out of our model. We reported $1.7 billion in cash as of March 31, which supports our cash runway to the second half of 2025 before which we'll have a tremendous amount of data to share. And then we are incredibly proud of what we now believe is an industry-leading pipeline, especially in late-stage I&I with over $15 billion of sales potential supported by the ongoing launch of VTAMA and with a number of potential best or first-in-class programs.
We've said all along on Slide 6 that 2023 was going to be our biggest year, we are right at the midway point, both in terms of the year and in terms of the data that we've been look forward to sharing. We've continued to provide updates on VTAMA as we will do today, and this has been another great quarter of progress for that launch. We've now shared data for both of our Phase III studies in atopic dermatitis for VTAMA, data that we think is really, really exciting and will support an important product in that class pending potential DA approval next year. We've now supported data from both the induction and chronic periods of our study of RVT3101, our HTTL1A antibody in ulcerative colitis, which again is phenomenal data. We think so really top-end efficacy that has the potential to really matter for patients and to be an important new option we'll continue to ride updates on that program.
Still coming and obviously closely watched our number of updates from our anti-FcRn franchise, including the healthy volunteer study for IMVT-1402, which we hope and believe will establish that program as a best-in-class anti-FcRn antibody as well as a number of ongoing trials in bitoklimab to show continued efficacy of that agent and the class in multiple indications. And then finally, in the fourth quarter of this year, and we will talk more about this before it comes, we have our readout of brepocitinib or TYK2/JAK1, it's a potentially pivotal 102 studies in SLE, which we think has the potential to be, again, transformational top-level efficacy in that patient population.
And on Slide 7, just as a reminder, we are just very proud of our portfolio of our pipeline overall here with a number of late-stage agents that we think matter in some of the biggest classes, certainly in immunology. And we will continue to add to this pipeline as opportunities present themselves. Obviously, we made some really important additions within the last 12 months with IPT4102 and RVT3101. And I hope we can find more just like those 2 to bring on in the coming year. So I will start in the next section here with an update on the commercial launch of VTAMA.
On Slide 9, I'll say we are very excited about the way that demand continues to evolve for VTAMA. We are the best launching novel topical. We believe in psoriasis history. We are obviously the best selling branded topical in psoriasis and have been since very shortly after our launch. We continue to like the way that the demand has grown, and we expect to see it continue to build through the end of this year as various things including coverage and our DTC efforts build. On Slide 10, some really great progress here in the early launch that we just wanted to make sure we hit. First of all, we did $13.7 million in net product revenue for the March 31 quarter, which is up a pretty good degree from $9 million or $9.2 million in the prior quarter.
So obviously happy with the sales number. Maybe frankly, even happier with the progress that we made during the quarter in gross net yield, up from 18% to 25%, which is a reflection of the breadth of coverage that we added, frankly, faster than expected in the first quarter of this year, and we've continued to add coverage since. So we're really happy with that. In some ways, I think we managed to pull forward gross to net improvements earlier this year, and we continue to feel good about our trajectory through the year. We'll talk more about that over time.
From a coverage perspective, on Slide 11, we're now up to 76% of commercial lives covered within a year of launch. This is better by a meaningful margin than our expectation at the time we launched the product. This includes the addition of 2 major -- 2 national PBM formularies, 2 national health plan formularies during this period. An important regional PV and formulary well with 18 ABS plans. So just really great coverage. And as a reminder, the significant majority of that coverage is single step through steroids, which is exactly where we wanted to be when we launched the product and which gives us access to the patient population that matters most to us. As a reminder, there are almost 400,000 topical corticosteroid scripts every week between psoriasis and atopic dermatitis. And we're currently doing about 4,000 or a little bit more than 4,000 scripts a week. So we have a ton of room to grow into that opportunity, and we're really excited to do that both in psoriasis today and pending FDA approval in a dermatitis as well.
Speaking of atopic dermatitis, on Slide 12 here, just a little reminder we've talked a lot about this data. We got together to talk about the Dorint data on the call in March, we put out the DR1 data as well, which is extremely consistent. This is just -- it's great data. We are really excited about this. It's data that is really -- it's terrific on IGA response rates, really, really good E75. And I'm very happy with the quality of the idea here. The reported data was in adults that looked very good in children as well and about equivalent. And we feel like NAD, which is really a disease market by itch, these data are going to make a really big difference for patients.
And as a reminder, this study went all the way down to pediatric patients in H2, which is right because the pediatric patient botulin maybe is large and the unmet need there is significant. Across all patients and especially in pediatric patients on Slide 13. One thing that you really care about with a topical agent is safety. And I think it's clear from our data that the tolerability of this agent in atopic dermatitis is very, very good, frankly, even a little bit better than we saw in psoriasis with very low rates of contact dermatitis, very low rates of follicular events. Just a clean profile that gives us exactly the profile of a product we think will matter to physicians and patients. So really excited about the data from a safety perspective as well.
I won't spend too much time on the crush hot comparison on Slide 14, but this is data in a moderate to severe patient population that looks competitive with or better even a number of systemic agents and certainly in the same ballpark or better than anything else that is topical in atopic dermatitis. So more updates to share on Dermavant over the course of the year. Looking forward to continue cover, looking forward to progress in the franchise. Looking forward to providing updates on the SNDA filing for Vitamin D, which we expect to be at the very beginning of next calendar year. Looking forward to sharing those in quarters to come.
So I'm going to pivot now and give a brief reminder. This is data that we put out just last week. So I won't spend a lot of time on it with RVT3101. On Slide 16, we really believe this program is in a class of its own, right? Anti-T antibodies at this point between our program and one of our competitors that also reported data earlier this year. This is a remarkable class of drugs that has shown incredible efficacy, and we are very proud to be the first agent to show sort of real and proper-blinded 52-week data last week. And it's great data. We showed substantial improvements between week 4 and with 56 across basically all of the endpoints in our go-forward dose. We are the only anti-TL1A antibody at this point with valid long-term efficacy data, and we have over 200 patients of set data. we have a biomarker that we've talked a bit about that is relevant to 60% of the UC population with meaningful improvement in efficacy relative to the all-comers population.
And then safety has been very good for the agent in the study so far. And we've seen no impact of immunogenicity on the program, which we know was a question that people are hoping to get run to ground in this trial. So we're now full speed ahead here with a plan to run a simple Phase III program with a single subcutaneous dose in the near future, and we'll provide updates on that just after our discussion with FDA, which is coming this summer.
As a reminder of the data, and I'll go quickly on this on Slide 17. We saw modified Maoclinical remission. This was in our KNR Phase III dose, go from 29% to 14 weeks to 36% at 56 weeks, a remarkable 50% of week 56 in endostatic improvement. And then endostatic remission, this is an [indiscernible] of 0. It's something that, frankly, very few agents hit, and so we don't typically see it reported. And we were really excited with what we saw there with 21% of patients in the all-comers population on the Phase III dose, achieving a clear endoscopy.
Once you overlay the biomarker on Slide 18, that data looks even better it gets up to 43% clinical remission in the Phase III dose at week 56, 64% of patients meeting the are endostatic improvements. And again, a really exciting 36% of patients in endostatic remission by week 56, which no look, we didn't measure specific antifibrotic markers here. But personally, I look at this data suggesting that we are having a potential disease-modifying impact on these patients. So really exciting.
Another topic -- and this is also data that we shared, but just as a reminder, in a large patient population here of really the whole study in patients who are biologic experience, with our biomarker, we saw, frankly, just phenomenal data at 56 weeks, 34% clinical remission for biologic experience patients, 45% endostatic improvement. This is some of the best data that's been shown in bilas-experienced patients, which are generally recalcitrant and hard to treat. And as a reminder, this includes patients on doses other than our optimally chosen dose. So we expect when we generate large end data in our Phase III studies that there's room for improvement even over these really great numbers. So very excited about the potential for efficacy in the biologic experience population. And I think any way that we look at our data where there's sufficient and to reach a judgment, we feel very confident that this is going to be a great agent in later lines of therapy.
Obviously, all that has to be backed up by a good safety profile. And one of the really exciting things about the TL1A class, and you can see our safety data on Slide 20 is because of the way TL1A works a mechanism because it is really only sort of present in disease inflict tissue in terms of signal amplifier you don't get some of the infection and other things that you see in other anti-inflammatory classes. And so we had no severe infections observed and no infections observed greater equal to 5% rate in the chronic period.
And just generally, we saw a really good safety profile 356, well tolerated at all doses and serious AEs were practice determined by the sponsor not to be related to drugs. So very clean safety profile that we think is going to help the utility of the drug going forward. And then finally, on the data on Slide 21 as a reminder, one of the questions that we got a lot going into the maintenance period was whether I mean is was going to matter. We were reasonably confident that it was not.
What you can see on this slide in the chart in the middle, this is across the data pool across all 9 arms of the study. Patients with ADAs by and large, had somewhat better clinical remission than patients without ADAs, and it was uncorrelated with the quartile of ADA titer. We don't think this is a real effect, obviously. We just think this is noise. We think the ADAs are having no impact on safety or efficacy across all the arms of the study. And we have said we expect that our rising antibody rate to be flat to down. I perhaps say it was 0 at week 56, and the expected Phase III dose. So we have no patients mutualizing antibodies that 56 on that are.
On Slide 22, without belaboring the point too much, we feel really great about the amount of data that we have here, and it is quite differentiated relative to the field here. We have over 400 subjects dosed, including 250 patients dosed across an IV and 3 subcutaneous doses, 200 patients dosed across 3 seasons out to a year of dosing, just hundreds of basis dose no matter how you cut it. We are the only agent here with subcutaneous data, the only agent here with anything like this quantum of long-term data. Our biomarker, which prospectively specified has obviously been tested in many patients, and we expect a commercial form factor that is a once-monthly subcutaneous auto-injector. So we really feel great about our profile versus the other agents in this class, which also have where we expect will show promising data given the quality of the target.
Finally, on Slide 22, I wanted to highlight, we have initiated, as we mentioned last week, a Phase II study in Crohn's disease. It's just over 100 patients. It is 2 doses subcutaneous monthly similar in that sense to the Phase IIb study that we just ran in UC. There will be 12 weeks of dosing followed by a 40-week chronic period, again, similar with a similar set of endpoints, which you can see on Slide 22. This was a study that we wanted to start very quickly because we realized, as we took a step back that we felt like we could run a proper dose ranging study in Crohn's patients without giving up any ground on the opportunity to be first-in-class in Crohn's, and that would allow us to run just as we are doing and you see a straightforward, simple single-dose Phase III study that will be optimal for patients. One question I expect we'll get is in placebo arm in the study. The basic answer to that is we want to get the dose ranging study done as quickly as we possibly could. And so we wanted to make this a really attractive study for patients to enroll in starting now. And so we're trying to have that study up and running.
So overall, as a reminder on Slide 14 -- or sorry, Slide 24, just really excited about this program. I think it is a major anchor in our late-stage pipeline. We think it will be the first-in-class anti-TL1A antibody with an efficient well validated path we will on a single dose carried forward to Phase III. We think we are uniquely positioned to overcome some of the limitations of IVD therapies, including efficacy in later-line therapy with sustained clinical remission and endoscopic improvements among the highest ever reported.
We think our biomarker further differentiates this class and our agent versus other treatment options for IBD patients and gives us an opportunity to select for patients with an even higher clinical remission rate, although notably, we think our data clearly supports a study in an all-comers population, irrespective of biomarker status or a line of therapy. And our expectation is that, that is the patient population that we will be targeting for approval. And then finally, just many opportunities for additional growth, including the Crohn study I just mentioned as well as the dual targeting of both inflammatory fibrotic pathways, opening up a range of large markets and high end that need indications that go well beyond Diab D, and we'll look forward to sharing more on that as soon as we're underway with additional studies.
Finally, I want to spend a few minutes on IMG-1402 and our anti-FcRn franchise. Obviously, Immunovant has spoken about this program. And there's no new updates in the section, but just wanted to remind everybody of what was coming, given how excited we are about this program. So on Slide 26, as a reminder, we have a proper franchise in antisera antibodies with our first-generation batoclimab currently in multiple pivotal studies across MDD and CIDP with data coming over the next couple of years in those studies as well as others.
And then we have our next interaction antibody, INT-1402, which we believe will have the same best-in-class suppression of IgG as batoclimab, while showing minimal impact on albumin in LDL and therefore, being useful for chronic dosing and diseases with an even larger population. We have data coming from that program in August, September for single sending dose data in October November for multiple sending dose data. And we think that has the potential to establish that agent is best in class.
As a reminder, both of these agents are proper classic subcus. They are subcutaneously administered. They are simple subcu-injections. They will be sort of at home administered, we believe, and sort of very straightforward comparable with other subcu-programs on the market, which we think is also at this point, something differentiated and something we do not believe any of the other agents in the class have today.
Our Phase I study that's ongoing IMVT-1402 has, as I said, single ascending and multiple ascending dose cohorts. That study is underway, and we are looking forward to sharing that data later this year, as I mentioned. And we believe that the data that we have in hand is likely -- we have NHP data that we've shared on these calls and other forums. And based on our data for batoclimab, both on albumin and on IGG, we think the SAD data, which we will be putting out a at the end of the summer may be usefully predictive of MAD data. I get a fair number of questions on the war for success.
And I guess the one thing I'd like to say is, look, we believe based on the NHP data and based on the way these programs are engineered that we should be clean and albumin in LDL. Remember that the LDL assay has about a 10% variability and the albumin assay is a little bit more specific than that, but has some variability. And frankly, although we have seen to be clear, none of this data today. So I have no information about what this will show and our expectation from the NHP days but ought to be clean. Our advisers tell us that even up to, for example, a 10% of surge in LDL would not be clinically meaningful. So looking forward to sharing that data, optimistic given the way that drug was engineered as well as the NHP data that we should have a good result there and look forward to getting that together with the Immunovant team later this year to go through it.
Finally, I'll give a brief financial update on Slide 21, and then we'll open the line for Q&A. So we showed net revenue of $27 million, including net product revenue of $14 million for the quarter ending March 31. And or net revenue of about $60 million and net product revenue of about $28 million for the fiscal year. For the quarter, we had R&D expense of $130 million or adjusted R&D expense about $126 million. And SG&A was $126 million or adjusted about $100 million. So consistent with prior quarters from a spend and burn perspective.
And notably, we ended the fiscal year with $1.7 billion in cash equivalents, which we feel good about as far as carrying us into that second half of 2025 guidance giving us lots of opportunity to turn over data cards. So look, I won't go through all of the catalysts on Slide 33. I'll just say we've talked about some of them here, but there is a long list to come of important developments, including in programs we've talked very little about frankly. And so we're looking forward to sharing that data look forward to getting back together. It's been a tremendous fiscal year for us. It's hard to believe this is only the second 10-K we filed. I want to thank all of our patients and the team at Roivant as well as those listening on this call for being with us. And with that, I will pause and turn the line over to Q&A. Thank you, everybody.
