Incyte Corporation (NASDAQ:INCY) Q4 2023 Earnings Call Transcript February 13, 2024
Incyte Corporation misses on earnings expectations. Reported EPS is $1.06 EPS, expectations were $1.21. Incyte Corporation isn’t one of the 30 most popular stocks among hedge funds at the end of the third quarter (see the details here).
Operator: Hello, and welcome to the Incyte Fourth Quarter Earnings Call and Webcast. [Operator Instructions] As a reminder, this conference is being recorded. It’s now my pleasure to turn the call over to Ben Strain, Associate Vice President, Investor Relations. Please go ahead, Ben.
Ben Strain: Thank you, Kevin. Good morning, and welcome to Incyte’s fourth quarter 2023 earnings conference call. Before we begin, I encourage everyone to go to the Investors section of our website to find the press release, related financial tables and slides that follow today’s discussion. On today’s call, I’m joined by Hervé, Barry, Pablo, Steven and Christiana, who will deliver our prepared remarks and will participate in the Q&A. I would like to point out that we will be making forward-looking statements, which are based on our current expectations and beliefs. These statements are subject to certain risks and uncertainties and our actual results may differ materially. I encourage you to consult the risk factors discussed in our SEC filings for additional detail. I will now hand the call over to Hervé.
Hervé Hoppenot: Thank you, Ben, and good morning, everyone. So, on Slide 5, we achieved another strong year with 2023 product and royalty revenues growing 14% versus 2022 to reach $3.7 billion, continuing the strong performance we have delivered since 2018. We also achieved [a symbolic] (ph) milestone in the fourth quarter. Total product and royalty revenue reached $1 billion quarterly for the first time, driven by the continued growth of Jakafi and successful launch of Opzelura. So, moving to Slide 6, 2023 Jakafi net sales were $2.6 billion, growing 8% versus the prior year with growth across all indications year-over-year. And Opzelura saw strong momentum in 2023, growing 162% to $338 million, driven by new patient and refills in both AD and vitiligo.
We expect Opzelura to continue to be a key contributor to growth in the next year. On Slide 7, our clinical pipeline has the ability to deliver transformative therapies to patients across multiple programs and provides the opportunity for 10 high-impact launches by 2030, as presented recently in San Francisco. Importantly, some of the programs highlighted on this slide are de-risked as they are post proof of concept, including axatilimab, which has been submitted to the FDA for approval, RUX cream in pediatric atopic dermatitis to be submitted to the FDA by mid-year, RUX cream in HS where we have randomized Phase 2 data, and povorcitinib, where we are in Phase 3 in HS, vitiligo and in PN, where we are on track to initiate a Phase 3 study this year.
Each of these programs have the potential to address a significant market and provide an opportunity to contribute to the top-line before the end of the decade. I would also like now to highlight the recent transaction with MorphoSys on Slide 8. As described in the press release we issued last week, we entered into an asset purchase agreement with MorphoSys, which gave us exclusive global rights for tafasitamab, also known as Monjuvi or Minjuvi. This acquisition provides a number of benefits to Incyte in the short term. First, going forward, we will now record all revenues from Monjuvi in the US, while eliminating MorphoSys’ share of the royalties ex US and all future milestone to MorphoSys. Second, we will realize significant operating efficiencies and cost synergies in US commercialization and in global development by removing redundant position and redundant external expenses and by simplifying the org chart.
Therefore, in 2024, this deal will add to Incyte’s revenue and will have a limited impact on operating income. For the future, while the currently approved indication of relapsed/refractory DLBCL represents a smaller opportunity for tafasitamab, we see upside potential in second line follicular lymphoma and marginal zone lymphoma with Phase 3 data expected later this year and in first line DLBCL, for which Phase 3 data are expected in 2025. These programs have been co-funded by MorphoSys until now and, if positive, Incyte will fully benefit from the upside from this indication. And this acquisition will be value accredit for Incyte in all scenarios. I will now turn the call over to Barry, who will discuss our commercial performance in more detail.
Barry Flannelly: Thank you, Hervé, and good morning, everyone. Starting with Jakafi on Slide 10. In the fourth quarter, Jakafi net product revenue grew 7% year-over-year to $695 million and grew 8% for the full year to $2.6 billion. Total patients increased 6% in 2023, with growth being seen across all indications. We experienced some variation in Jakafi dynamics during the fourth quarter, including an increase in patients on free drug as well as an inventory fluctuations. Recall, inventory grew down modestly in Q3 and rebounded in the fourth quarter. Additionally, we anticipate the increase in patients on free drugs seen at the end of 2023 to reverse and return to more normalized levels through 2024, supported by the lower out-of-pocket expenses under the Part D redesign.
Christiana will provide more details on these dynamics in her prepared remarks. We continue — and we expect continued growth of Jakafi and have updated the full year net product revenue guidance for 2024 to a range of $2.69 billion to $2.75 billion. As highlighted on Slide 11, Jakafi continues to maintain its leadership and market share in MF, driven by its unmatched product profile. Based on market research, other competitors have not had an impact on Jakafi in regards to total patient market share or new patients, and is consistent with our expectations. Jakafi demand remains strong and we expect continued future growth driven by maintaining its leadership as standard of care in myelofibrosis, growth opportunities in polycythemia vera and chronic graft-versus-host disease, as well as earlier use in chronic GvHD.
Additionally, we anticipate the positive changes in out-of-pocket expenses for Medicare Part D patients to contribute to the growth in the coming years, with the biggest impact starting in 2025. Turning to Slide 12 and Opzelura fourth quarter performance. Opzelura net product revenues in the fourth quarter were $109 million, up 78% when compared to the same quarter last year. Total 2023 full year net sales grew 162% versus 2022 to reach $338 million. US patient demand increased during the quarter with total prescriptions growing 77% year-over-year and refills growing by 22% versus the prior quarter. The weekly prescription trend, as shown on the right, demonstrates typical end of Q4 dynamics, as well as the continued growth of Opzelura, which is coming from both atopic dermatitis and vitiligo.
In AD, growth was primarily driven by Opzelura’s efficacy and impact on inflammation and itch. In vitiligo, where Opzelura is the only approved treatment for repigmentation, growth was driven largely by refills, improved access and our educational initiatives. We remain very optimistic about the long-term potential of Opzelura as we continue to see strong uptake. The launch continues to be strong and it’s gaining positive momentum with both physicians and patients as Opzelura becomes established as one of the best recent dermatology launches. Looking at the first 27 months post FDA approval, Opzelura continues to outperform other dermatology products on a launch aligned basis when measured by monthly dermatologists prescribed TRxs on the left and when comparing quarterly net revenues on the right.
The successful launch of Opzelura is driven by its compelling product profile, its ability to address significant unmet need in both atopic dermatitis and vitiligo and our strong market access relative to competition where we continue to improve access and growing net sales. Turning to Slide 14, we have a number of initiatives in place for Opzelura to drive demand in 2024 in both AD and vitiligo. We know that based on Opzelura’s compelling efficacy and safety, healthcare professionals want to use Opzelura sooner in the treatment algorithm. In addition to securing improved access for 2024, we are also continuing to look for ways to improve utilization management and we have an exceptional value proposition that supports these advancements. For vitiligo, we continue to drive patient awareness through consistent marketing campaigns with the goal of educating and inspiring these patients with positive real-world patient experiences.
We believe this will drive further demand and activate patients to discuss treatment options with their dermatologists. With that, I’ll turn the call over to Pablo.
Pablo Cagnoni: Thank you, Barry, and good morning, everyone. I want to highlight some of the key R&D milestones that we accomplished in 2023 and to provide a framework for how we are evolving our R&D focus with near-term goals to increase the rigor of our decision making, accelerate the progression of our pipeline and to optimize our resource allocation. As you can see on Slide 16, we have three areas of focus where we’re building a robust and diverse portfolio of medicines for the treatment of MPNs and graft-versus-host disease, oncology and inflammatory diseases. We’re advancing a pipeline to deliver impactful innovation with a focus on best-in-class and our first-in-class differentiated medicines in areas with large unmet medical needs.
Our discovery process is targeting pathway-centric and leverages cross program knowledge and deep biology expertise in our established disease areas of interest to identify and prosecute novel targets as well as disease and genotype-specific dependencies with a mortality agnostic approach. In addition to our established small molecules expertise, we have expanded our drug discovery capabilities to include monoclonal antibody discovery in-house and have access to bispecific antibody discovery capabilities through our partnership with Merus. Turning now to Slide 17, we made significant advancements across all three priority areas of focus in the R&D portfolio in 2023. In MPNs and graft-versus-host disease, we submitted the BLA for axatilimab for the treatment in third line chronic graft-versus-host disease.
We presented updates for our BET and ALK2 inhibitors in MF and highlighted our new potentially transformative therapies for MF, PV and ET, our mutant CALR monoclonal antibody, which is enrolling well in a Phase 1 study and our JAK2 V617F inhibitor for which we plan to initiate a Phase 1 study in the next month. In oncology, we initiated several monotherapy and combination studies with our small molecule oral PD-L1 inhibitor and highlighted early signs of clinical activity with our small molecule CDK2 inhibitor. Additionally, we unveiled a new program in development, our KRASG12D inhibitor, which entered the clinic earlier this year. Steven will provide more detail on the KRASG12D program in his prepared remarks. In dermatology, we continue to maximize the potential of ruxolitinib cream.
In 2023, Opzelura was approved in Europe for vitiligo as the first and only approved treatment for repigmentation. We also presented positive Phase 3 data in pediatric atopic dermatitis and announced that the primary endpoint was met in a randomized Phase 2 study in patients with hidradenitis suppurativa. For povorcitinib, we presented a positive randomized Phase 2 data in vitiligo and initiated two Phase 3 studies for patients with extensive vitiligo. We also announced that povorcitinib had met the primary endpoint in a randomized Phase 2 study in patients with prurigo nodularis, and we initiated two randomized Phase 2 studies, one in patients with asthma and another in patients with chronic spontaneous urticaria. We believe that with ruxolitinib cream and povorcitinib, we’ll be the only company with the ability to address a broad spectrum of patients from mild to severe, potentially providing both the topical and oral option for a number of indications, including prurigo nodularis, hidradenitis suppurativa and vitiligo.
Apart from an exhaustive list of all the R&D achievements in the past year, this demonstrates that 2023 was a very successful impactful year for Incyte and it serves as a foundation for a number of pivotal trials that will deliver results in the next few years. As you can see from Slide 18, we anticipate that 2024 will be another very exciting year with multiple clinical and regulatory milestones. Steven will provide more details on these, but I would like to highlight certain events. Within our oncology pipeline, we believe that our potentially best-in-class CDK2 inhibitor is an active agent and we look forward to sharing data as well as our development plan later this year. In addition, the pivotal trial of tafasitamab in patients with follicular and marginal zone lymphoma, also known as inMIND, we’ll read out later this year, and we look forward to sharing those results.
We submitted a BLA for axatilimab late last year and we look forward to working with the FDA to make axatilimab available to patients with chronic graft-versus-host disease later this year and to initiate additional combination studies in patients with less pre-treated chronic graft-versus-host disease. Within our dermatology portfolio, we expect to submit the sNDA for Opzelura for pediatric atopic dermatitis and expect multiple data readouts throughout the year. With that, I would like to pass the call to Steven, who will provide further details on our clinical development pipeline.
Steven Stein: Thank you, Pablo. Starting on Slide 20, in December, we presented more than 40 hematology and oncology abstracts, including a plenary presentation at the ASH Annual Meeting. Key highlights included a plenary scientific session, which featured the full data from AGAVE-201, evaluating axatilimab, an anti-CSF-1R monoclonal antibody in patients with chronic graft-versus-host disease and additional data from the Phase 1/2 study of zilurgisertib, Phase 1 data from our BET inhibitor and preclinical data of the JAK2V617F inhibitor. For our BET inhibitor, dose escalation is ongoing. In monotherapy and in combination therapy, we are seeing reductions in spleen length and volume as well as improvements in both symptoms and hemoglobin, suggesting that this is an active compound.
We plan on advancing this program to Phase 3 later this calendar year. As we get closer, we will provide additional details on study design and timing. Based on the efficacy and favorable safety profile seen in the Phase 2 AGAVE-201 pivotal study, the BLA for axatilimab was submitted to FDA for approval for the treatment of patients with chronic graft-versus-host disease. We anticipate a decision by the FDA in the second half of 2024 and are excited by the possibility of bringing a new treatment option to these patients. We continue to expand and advance our IAI and dermatology portfolio, as seen on Slide 22. For ruxolitinib cream, we recently presented positive Phase 3 data in pediatric patients, where RUX cream met its efficacy endpoints for both Investigator Global Assessment treatment success and EASI-75.
We expect to submit the sNDA by the middle of 2024 with potential approval in 2025. We also disclosed that RUX cream met the primary endpoint in the Phase 2 study in mild to moderate hidradenitis suppurativa, and we expect to present those results at a medical conference later this year, while a Phase 3 study is being evaluated. Ruxolitinib cream is also currently being evaluated in two Phase 3 studies in prurigo nodularis and two Phase 2 studies in lichen planus and lichen sclerosus, with data expected for both later this year. Povorcitinib, our oral JAK1 inhibitor is currently being evaluated in Phase 3 studies in hidradenitis suppurativa and vitiligo, and we have recently announced that povorcitinib met the primary endpoint of greater than or equal to a 4 point improvement in the itch NRS across all three treatment groups in a Phase 2 study in prurigo nodularis.
We expect the full data set at a medical conference later this year and Phase 3 planning is underway. Our earlier stage dermatology program, our IL-15 receptor beta antibody, has begun evaluation in healthy volunteers. Moving to Slide 23. Last week, at the European Hidradenitis Suppurativa Foundation Conference, we presented additional data from the open label extension of Phase 2 study of povorcitinib in HS. As a reminder, povorcitinib demonstrated dose dependent efficacy in patients with HS during the initial placebo control period at week 16. The data presented demonstrate that treatment with povorcitinib through week 52 resulted in a decrease in disease severity as classified by the International HS Severity Scoring System, or IHS4. At week 52, a significant decrease in disease severity was observed with approximately 25% of patients achieving an IHS4 score of zero, which represents the complete resolution of abscess, nodule and draining tunnels.
On Slide 24, an additional analysis was maintenance of response, which demonstrates that povorcitinib treated patients who achieved a response at week 16 were likely to maintain the HiSCR response through week 52. Both of these datasets build upon povorcitinib’s potential as a best in disease medicine for patients suffering from HS. As a reminder, two Phase 3 studies evaluating povorcitinib in HS, STOP-HS1 and STOP-HS2, are ongoing and enrolling very well. Our high-potential oncology pipeline is currently focused on three advanced programs. The first is tafasitamab, which has currently been evaluated in two Phase 3 studies in patients with follicular and marginal zone lymphoma and in patients with previously untreated diffuse large B-cell lymphoma.
We’re expecting Phase 3 results for follicular and marginal zone lymphoma or the inMIND study in the second half of this year with the first line diffuse large B-cell lymphoma front line study readout in 2025. The second is our small molecule oral PD-L1 program. We have multiple ongoing studies as monotherapy or in combination with other agents such as axitinib, adagrasib and ipilimumab, and we expect to have combination data later this calendar year. And the third program is our small molecule CDK2 inhibitor, where we recently announced early signs of clinical activity with multiple patients demonstrating partial responses. We expect to share data as well as the development plan later this calendar year. On Slide 26, we recently announced that INCB161734, a potent, selective and orally available KRAS G12D inhibitor recently entered the clinic in a Phase 1 study.
This program has shown encouraging preclinical anti-tumor activity in xenograft models with no currently approved G12D targeting agents could address a high unmet need. As a reminder, the KRAS G12D mutation is found in approximately 40% of pancreatic ductal adenocarcinoma, 15% of colorectal cancer, and 5% of non-small cell lung cancer, and could thus represent a significant opportunity for Incyte if successful. In summary, we anticipate a number of upcoming pipeline updates in 2024, including sharing top line results from both the Phase 2 studies in RUX cream in HS and povorcitinib in PN at a medical conference in the first half of this year. Second half of the year is looking to be catalyst-rich period, as highlighted on Slide 20, that we anticipate — includes but is not limited to an approval with axatilimab, Phase 3 results from tafasitamab and the initiation of a number of Phase 3 studies including with our BET inhibitor.
With that, I would like to turn the call over to Christiana for the financial update.
Christiana Stamoulis: Thank you, Steven, and good morning, everyone. 2023 was another year of strong financial performance with total product revenues of $862 million for the fourth quarter of the year and $3.2 billion for the full year, representing a 13% and 15% year-over-year increase, respectively. Total royalty revenues, which are primarily comprised of royalties from Novartis for Jakavi and Tabrecta, and royalties from Lilly for Olumiant were $150 million in the fourth quarter and $523 million for the full year, up 13% and 8%, respectively, compared to 2022. Total revenues grew 9% in the fourth quarter compared to the prior-year period, reaching the $1 billion mark, an important milestone for Incyte. For the full year, total revenues were $3.7 billion.
Turning to Jakafi on Slide 30. Jakafi net product revenues were $695 million for the fourth quarter and $2.6 billion for the full year 2023. In 2023, Jakafi net sales grew 8% compared to the prior year. Jakafi sales were negatively impacted by a significant increase in free drug in the fourth quarter of the year, driven by an increase in the number of patients seeking support from Incyte’s Patient Assistance Program. The impact of the increase in free drug was more than offset by an increase in channel inventory levels. This increase was in anticipation of patients moving into paid demand starting in Q1 of 2024. The increase in Q4 channel inventory levels represented $46 million in sales. Turning now to Opzelura, net product revenues for the fourth quarter were $109 million, representing a 78% increase year-over-year, driven primarily by increased patient demand.
For the full year, total Opzelura net product revenues were $338 million, representing a 162% increase compared to the prior year. Moving on to Slide 32 and our operating expenses on a GAAP basis. Total R&D expenses were $444 million for the quarter, representing an 11% year-over-year decrease, which was primarily as a result of the $70 million upfront payment made as part of the Villaris acquisition in Q4 2022 and partially offset by the $20 million development milestone payment to former Villaris shareholders in the fourth quarter of 2023. For the full year 2023, total R&D expenses were $1.6 billion, representing a 3% year-over-year increase. This increase was primarily due to the progression of our pipeline and was mainly offset by lower upfront and milestone expenses in ’23.
Total SG&A expenses were $294 million for the fourth quarter and $1.16 billion for the year. The year-over-year increase of 8% for the fourth quarter and 16% for the full year were mainly due to increased sales and marketing activities for Opzelura in both the US and Europe, unfavorable effects and timing of certain G&A related expenses. Moving on to 2024, I will now discuss the key components of our guidance on a GAAP basis, which includes revenues and expenses related to the recent acquisition of the exclusive global rights to tafasitamab, but excludes any potential impact related to the accounting treatment of the $25 million purchase price paid. For Jakafi, we expect net product revenues to be in the range of $2.69 billion to $2.75 billion, on track to achieve our long-term guidance of over $3 billion in net product revenues by 2028.
We expect net product revenue growth to be driven exclusively by continued demand growth, and be partially offset by lower net pricing as a result of IRA imposed price increase caps and continued growth in 340B volumes. As in previous years, we expect the gross to net adjustment to be higher in the first quarter of the year relative to the previous quarter and subsequent quarters due to the higher deductibles and our share of the donut hole for Medicare Part D patients, which are primarily impacting the first quarter of the year. While for Opzelura we will not be providing full year guidance at this point, in the first quarter, we expect to see again the effect of typical Q1 dynamics on net sales, including higher patient out-of-pocket costs due to the planned deductibles resetting at the beginning of the year and the impact of holidays, medical conferences and other events on dermatology product sales.
As of a result, Q1 Opzelura net product revenues are expected to be below the previous quarter and the subsequent quarters and represent a smaller share of the full year net product revenues, consistent with what we saw in 2023. For other hematology/oncology products, which now include Iclusig, Pemazyre, Monjuvi and Minjuvi, we expect total net product revenues to be in the range of $325 million to $360 million, which at the midpoint represents approximately 47% growth over 23%. Turning to operating expenses on a GAAP basis, we expect COGS to range from 7% to 8% of net product revenues, which is in line with 2023. R&D expense is expected to be in the range of $1.72 billion to $1.76 billion, representing 7% growth at the midpoint versus 2023, primarily driven by the progression of our pipeline.
We expect SG&A expense for the year to be in the range of $1.21 billion to $1.24 billion, representing 6% year-over-year growth at the midpoint, primarily driven by the inclusion of sales and marketing expenses associated with Monjuvi in the US under SG&A, whereas prior to the acquisition of full product rights, they were included under the collaboration profit or loss share. Operator, that concludes our prepared remarks. Please give your instructions and open the call for Q&A.
Operator: Certainly. We will now be conducting a question-and-answer session. [Operator Instructions] Our first question is coming from Kripa Devarakonda from Truist Securities. Your line is now live.

Kripa Devarakonda: Hey, guys. Thank you so much for taking my question. On Jakafi myelofibrosis, thank you so much for providing the market share details on patients and share of new patients. I was just wondering if you anticipate stabilization of Jakafi share at these levels. And if collaborative were to be approved in combination with RUX, presuming it happens sometime next year, should we expect to see an inflection point? Thank you.
Barry Flannelly: So, stabilization of market share in myelofibrosis. So Jakafi, as you know, is the leader in myelofibrosis because of its safety, efficacy, overall survival, and really tolerability, which is really a big advantage. We think that myelofibrosis will continue to be the largest portion of our patient share until polycythemia vera patients ultimately take over, because you know those stay on for long period of time. Your question around pelabresib, if and when it gets approved in combination with Jakafi, of course, that’s a good thing for us. If in fact the profile of the drug is as it appears or the combination is as it appears, then many physicians may choose to use that combination and Jakafi will only benefit, but we have to wait and see what happens with the approval process.
Kripa Devarakonda: Great. Thank you so much.
Operator: Thank you. Next question is coming from Andrew Berens from Leerink. Your line is now live.
Andrew Berens: Hi. Thanks. Wondering if you guys could expand upon the development of Jakafi XR in light of the recently announced bid by Novartis for MorphoSys. Does Novartis’ control of Jakafi outside the US impact how you’re thinking about developing your BET inhibitor? Do they have any direction or say in any of the directions of the XR version of Jakafi? And then also just wondering if you think that an add-on drug to Jakafi in MS still requires a symptomatic improvement as an endpoint for regulatory endorsement, or do you think that there’s been a material change in thinking at the agency?
Hervé Hoppenot: So, let me take the piece about our agreement with Novartis on Jakafi and Steven can speak about the development of XR. So, the agreement is such that both parties can be co-developing new formulations of ruxolitinib in oncology, including the once a day. It has not been the case yet, but there is still an optionality for Novartis to co-develop XR if they wish, and that would mean that they would be able to commercialize the XR formulation outside of the US, but not in the US, where, obviously, it will be commercialized by Incyte.
Steven Stein: And then, Andy, I’ll take the other part of your question. So, for RUX XR, as Pablo communicated at the ASH Investor event, we have now clear feedback from the FDA that we need to do a new formulation strength, which are already developed, which are slightly higher and then demonstrate the EBA with those primarily around Cmin and AUC. That’s the clear guidance from the FDA. And we estimate this should be completed in a two-year process, so well before the LOE. It doesn’t affect our development of FTCs, fixed-dose combinations, with any of our products. So that continues. For our BET inhibitor, again, we showed data at ASH and alluded in my prepared remarks, we have clearly an active compound showing very good rates of spleen reduction, both volume and length, very good symptom improvement and occasional hemoglobin increases, just like seen with the other BET inhibitor.
We have been operating like other companies under the assumption that at least in first line, you need SVR35 and symptoms to date to get approvals. I can’t comment on where they are in their regulatory progresses or how the FDA may change in that regard. But that has been the standard to date. Thank you.
Andrew Berens: Okay. Thank you very much.
Operator: Thank you. Our next question today is coming from Michael Schmidt from Guggenheim. Your line is now live.
Michael Schmidt: Hey, guys. Thanks for taking my questions. I had one on povorcitinib. So, as we think about the opportunity for this drug in multiple indications, I believe the HS Phase 3 trial is most advanced. Could you talk a bit about your expectation on how the drug may be positioned relative to some of the biologics in HS, be it HUMIRA or some of the IL-17 antibodies? And then, also, in PN, where you had the positive top line data last year. Dupixent is obviously approved here. Again, could you talk a bit about how the drug might be fitting into that treatment paradigm relative to Dupixent? Thanks so much.
Steven Stein: Michael, hi, it’s Steven. I’ll start with your question. Thank you for the question. So, povor in HS, we think we have outstanding efficacy data, which we’ve now updated with a 52-week data that shows prolonged effect that’s maintained. And so remember, this is a JAK1 specific agent, about 50-fold selective for JAK1, has a long half-life and a very high volume of distribution, which may translate to more penetration in the skin, which is why we see this degree of efficacy showing to date. Both Phase 3 STOP-HS1 and HS2 are enrolling very, very well. So that probably speaks to also some of the belief out there in the agent, and that is clearly our lead indication as you alluded to. It’s hard to always cross-compare with many caveats to other studies where the drugs aren’t directly compared and you spoke about the IL-17 here and the biologics, and clearly, there’s some variable activity there.
You have to look at placebo corrected rates. But I think ours tackles multiple aspects of the disease pathophysiology, not just one interleukin. And as I said, the drug profile with a long half-life and high volume of distribution may lend itself to increased efficacy here. Obviously, time will tell with the Phase 3 data. It will be a once daily oral tablet, which offers that sort of convenience. In PN, what patients suffer from primarily is intense itching. And again, our Phase 2 proof of concept data is very strong in terms of the itch relief here and the ability to eliminate that symptom pretty quickly, as well as over time, disease resolution in the actual skin manifestations. There is, as you allude to, an approved agent there in Dupixent, but that has provided us the regulatory pathway on the way to go in terms of itch resolution and skin change resolution.
And again, we’ll offer the once-daily oral convenience. We think we’ll have a really good agents in terms of high efficacy there. So, we’re excited about this program as well. Thanks.
Operator: Thank you. Our next question today is coming from Vikram Purohit from Morgan Stanley. Your line is now live.
Vikram Purohit: Hi, good morning. Thanks for taking our questions. We had two on the pipeline. So first, for the ALK2 program, you’ve guided to POC data by mid-’24. We were just wondering what we can expect to learn with this update and what you will be reviewing specifically to decide what the next step of development could be for this program. And then secondly, for the mutant CALR antibody, when can we expect to see initial Phase 1 data there? And what are you hoping to establish to get conviction that the program is headed in the right direction? Thank you.
Pablo Cagnoni: Yes. Thank you for the question. This is Pablo. So, for the ALK2 inhibitor program, what we’re in the process of doing, and we need to establish this efficacy in a larger number of patients with newly diagnosed MF in combination with ruxolitinib. And that’s what the team is focused on right now and as we mentioned at ASH last December. So, we continue to push the dose. We need to get to doses of around 400 to 600 milligrams a day in order to get the maximum effect on hepcidin. Two, we need longer duration of therapy in a larger group of patients in combination with RUX. So, that will happen over the course of the year. We haven’t provided a specific timeline for when we’re going to disclose the data. But as we mentioned at ASH last year, it would happen this year.
And we’ll provide clarity on what the next steps for that program are. On the second question for the mutant CALR antibody program, we started dose escalation very recently, as you know. That study is accruing very well. The initial goals like for any first-in-human study, obviously, to establish that this monoclonal antibody is safe, get a good view of the pharmacokinetics in this first-in-human study and establish initial evidence of efficacy, which, in this case, will be by traditional endpoints in MPNs and also potentially a view on the effect of the mutant CALR monoclonal antibody on a real burden in some of these patients. That will happen over the course of the year. We haven’t decided yet when we’re going to present data, whether it’s this year, whether at some point in 2025.
Vikram Purohit: Got it. Thank you.
Operator: Thank you. Our next question is coming from Salveen Richter from Goldman Sachs. Your line is now live.
Unidentified Analyst: Good morning. This is [Anumeet] (ph) on for Salveen. Thank you for taking our question. We had one question on Opzelura. Outside of the 1Q dynamics that you spoke to, can you help us understand the forward launch trajectory in AD and vitiligo in the context of reimbursement and access and also gross to net in order to be fully able to capture the opportunity as you have additional indications coming in, in the coming years? Thank you.
Barry Flannelly: Yeah. Thanks for the question. So of course, as far as launch trajectory, we’re continuing to launch very well in both AD and vitiligo. We continue to expect growth in vitiligo just based upon our educational efforts directed both at patients and healthcare professionals. We know that the profile in AD in terms of its itch relief and clearance of the skin is unmatched for any therapy, topical therapy. We even believe that in AD, for example, the profile is so good that as far as payers are concerned, they’re interested in the fact that more than 80% of the patients will be clear and have their itch relieved and can delay or not even go on to biologics. So, we think those dynamics are good for both AD and vitiligo going forward, and we can — we’re looking forward to future growth. I’ll turn the call over to Christiana to talk about gross to net.
Christiana Stamoulis: So, in terms of gross to net, first of all, when you look 2023, the average gross to net was around 55%. Our goal is to maximize the value of Opzelura and maximize net sales. If going forward we make the decision to provide any additional discounts, it would be because we expect that this will improve access and we’ll have a disproportionate impact on volume and thus lead to higher net sales. So, as such, our comments are going to be focused on net sales versus gross to net in isolation.
Unidentified Analyst: Thank you so much.
Operator: Thank you. Our next question is coming from Derek Archila from Wells Fargo. Your line is now live.
Derek Archila: Hey, good morning, and thanks for taking the questions. So, one just piggybacking on the last. Just in terms of Opzelura, is there, one, any chance we get an update in terms of potential guidance this year? And then, will you ever look to kind of break out both kind of the vitiligo and AD kind of scripts or sales, if you could figure that out? And then, secondly, just on tafasitamab, I guess, can you quantify maybe the incremental growth opportunities you see for this asset in the follicular and marginal zone lymphoma indications? Thanks.
Barry Flannelly: So, as far as breaking out AD versus vitiligo, I think we’ve said before, it’s about 60% currently for AD, 40% currently for vitiligo. It could be changing a little bit. Ultimately, we expect vitiligo total tubes perhaps surpass AD. AD patients are many new patients always come on for atopic dermatitis, and in vitiligo, it’s about continued use and refills. As far as Monjuvi tafasitamab goes, obviously, we’re looking forward to, hopefully, positive data in follicular lymphoma, indolent lymphoma and in first-line diffuse large B-cell lymphoma. So, we think there’s great opportunities ahead for these two indications. We think it’s a great drug for lymphoma. Obviously, it’s a crowded marketplace, but we think the profile of the drug and the trials we put together for those two new indications are going to serve us well in the future.
Hervé Hoppenot: But in terms of calibration of follicular lymphoma, we need to see the Phase 3 data. It’s a fairly competitive place. There are a lot of new products. So, we need to see the Phase 3 data before we can give you a good calibration of that. I mean, the number of patients we are speaking about in the US is around…
Barry Flannelly: Well, there’s [29,000] (ph) patients in first-line diffuse large B-cell lymphoma. There’s about 13,000 patients in second-line plus in follicular lymphoma in the United States.
