Hello, and welcome to the Incyte Second Quarter 2024 Earnings Conference Call. [Operator Instructions] A question-and-answer session will follow the formal presentation. [Operator Instructions] As a reminder, this conference is being recorded.
It's now my pleasure to turn the conference 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 second quarter 2024 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 call. On today's call, I'm joined by Herve, Pablo, Christiana, who will deliver our prepared remarks. Barry, Steven, and Matteo will also be available for Q&A.
I would like to point out that we'll 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 Herve.
Herve Hoppenot
Thank you, Ben, and good morning, everyone.
So during the second quarter of 2024, we made significant progress across the business with strong performance on the commercial side, driven by Jakafi and Opzelura, transformation of our pipeline, where we made important decisions on our clinical programs, and capital allocation, where we closed the Escient acquisition and completed the large share repurchase.
Looking at Q2 revenue, total revenue grew 9% year-over-year, exceeding $1 billion, while net product revenue grew 10%, driven by the continued success of Jakafi and Opzelura, which I will detail in the following slides. We continue to make strategic decisions that are transforming our clinical pipeline, and during the second quarter we closed the acquisition of Escient Pharmaceutical which added two first-in-class medicines to our IAI portfolio. Additionally, we are intensifying our focus on and concentrating resources on those high potential program, which have the largest impact for patients and for Incyte.
We also recently completed a large $2 billion share repurchase, further highlighting our excitement and conviction in our clinical pipeline and commercial business, while retaining a strong balance sheet for potential further business development activities. Over the last 12-months, our clinical pipeline has significantly advanced and we are on track to deliver a number of best-in-class and our first-in-class differentiated medicines in areas where there are no or limited treatment options.
When comparing our pipeline today on slide six to where we were just seven months ago, we have added potentially transformative clinical programs including KRAS G12D, TGF-beta PD-1, MRGPRX2 and MRGPRX4, and we have deprioritized some of the immune oncology programs, including TIM-3 and LAG-3 antibodies, LAG-3xPD-1 bispecific, and the oral PD-L1 program. Pablo will describe this pipeline transformation in some details and will provide clarity on the potential timing of data availability.
Moving to slide seven, Jakafi net product revenues were $706 million, up 3% year-over-year. Paid demand increased 9%. As a reminder, the second quarter of 2023 benefited by approximately $37 million from channel inventory, which explains the 3% growth of net sales versus 9% growth of actual demand. Based on the strength in demand seen during the first-half of the year and anticipated growth for the balance of the year, we are raising the bottom end of our full-year 2024 Jakafi net revenue guidance to a new range of $2.71 billion to $2.75 billion.
Turning to slide eight and looking at Jakafi total paid demand by indication during the first quarter of 2022, ‘23 and ‘24. As you can see, unit growth continues to be strong. MF is stable year-over-year with modest growth since this quarter and the largest growth coming from both PV and GVHD. Jakafi continues to maintain its leadership in MF. Based on market research, discontinuation rates have remained stable in the first line selling over the past several months with minimal impact from competitors. These trends have been consistent with our expectations.
Moving to Opzelura on slide nine. Total Opzelura net product revenue in the second quarter were $122 million, up 52% when compared to the same quarter last year. The weekly prescription trend as shown on the right of slide nine reflects continued growth of Opzelura in both atopic dermatitis and vitiligo and U.S. total prescription for Opzelura grew 34% year-over-year, while refills grew 50% year-over-year. From an access perspective, we continue to see encouraging results since Opzelura moved to earlier position in Southern commercial plans, demonstrating a positive impact to net sales following the improved access.
Moving to slide 10, during the second quarter we made continued progress on the reimbursement of Opzelura in Europe. Opzelura is now reimbursed in Germany, France, Italy and Spain, and the $11 million in net sales during the second quarter were mostly driven by Germany and France. We expect Spain and Italy to start contributing to revenue beginning in Q3.
As shown on slide 11, Opzelura was the first therapy to gain full reimbursement in France through a new process called Acces Direct. This process has accelerated patients' ability to obtain Opzelura, while pricing negotiations were ongoing and were reflected in the increase in revenues seen in Q2.
And I will now turn the call over to Pablo.
Pablo Cagnoni
Thank you, Herve, and Good morning, everyone. Since joining Incyte one year ago, the R&D organization and I have been centered on accelerating the transformation of our pipeline to expand our leadership in treating patients with inflammatory diseases, MPNs, cancer, and graft-versus-host disease. By harnessing a culture of rigorous decision-making, intense focus, and excellence in execution, we have made considerable progress in advancing our goal of delivering best-in-class and/or first-in-class differentiated medicines in areas where there are no or limited treatment options.
As a result, we anticipate delivering more than 10 high-impact launches by 2030, several which are new molecular entities. As Herve already mentioned, we recently completed a strategic review of our pipeline to focus resources on programs with novel biology that hold the highest potential impact for patients. Based on available data, the evolving treatment landscape, and the evolution of our internal pipeline, we have decided to discontinue a number of programs, including our oral PD-L1 programs, our LAG-3 monoclonal antibody program, our TIM-3 monoclonal antibody program, and our LAG-3xPD-1 bispecific program.
This data-driven decisions will enable us to fully realize the potential of our pipeline by delivering significant value to patients and our shareholders. With a strong sense of urgency, we plan to achieve a number of important clinical milestones in the coming months. We will advance the development of 12 new molecular entities, and we will achieve up to seven pivotal readouts as well as eight readouts that will provide proof-of-concept and new indications for existing programs or for new molecular entities.
In the next few slides, I will highlight a number of these programs. In inflammation and autoimmunity, we continue to expand the breadth and novelty of our pipeline and expect to deliver multiple data sets beginning this year and beyond. We continue to evaluate the potential of ruxolitinib cream and povorcitinib across several new indications, including pediatric atopic dermatitis, prurigo nodularis, Hidradenitis suppurativa, chronic spontaneous urticaria, and asthma.
With the recent acquisition of Escient pharmaceuticals, We have added two potential first-in-class medicines that aim to address a number of debilitating conditions, including chronic spontaneous urticaria, chronic inducible urticaria, atopic dermatitis, cholestatic pruritus. We believe that with introduction of these new medicines for these conditions, we will see a greater number of patients seeking treatment, who are currently underserved with available therapies or who are currently not receiving treatment.
On slide 16, we continue to advance the development of ruxolitinib cream beyond AD and vitiligo to additional indications where it can provide significant value as either the first ever FDA approved therapy or first approved topical therapy for patients living with these dermatologic conditions. Based on the positive Phase III data in pediatric atopic dermatitis, the supplementary NDA submission is on track to be filed in the third quarter this year with a potential approval in 2025, which could provide an effective non-steroidal topical options for the 2 million to 3 million pediatric patients with AD in the U.S. In the most severe cases of this inflammatory disorder, pediatric AD may interfere with development, emphasizing the importance of delivering this medicine to these children as soon as possible.
Now turning to slide 17. We're currently conducting a Phase III study evaluating ruxolitinib cream in patients with prurigo nodularis, a chronic skin disorder that presents as multiple firm nodules commonly located on the extensive surfaces of the extremities and that are intensely pruritic. This study is enrolling well and we're on track to report results from the pivotal study next year with a potential approval as early as 2026. With no topical therapies currently approved for PN and over 100,000 patients on treatment, we see this as an important additional option for patients and a significant opportunity for ruxolitinib cream.
As shown on slide 18, we're continuing to execute a broad development plan for povorcitinib, our oral small molecule highly selective JAK1 inhibitor. Povorcitinib is currently being evaluated in Phase III studies in hidradenitis suppurativa, vitiligo and prurigo nodularis, and in randomized Phase II proof-of-concept studies in asthma and chronic spontaneous urticaria, with data in both expected in 2025.
Povorcitinib has already demonstrated outstanding efficacy and safety in a randomized Phase II study in moderate to severe hydrodynitis suprativa, an extremely painful inflammatory disease. As a reminder, we reported that at week 52, up to 29% of patients experience a high score 100 response, which is complete resolution of all manifestations. Povorcitinib also had rapid and profound impact on reducing pain, as highlighted in the chart on the bottom of slide 19, and represents the first potential oral therapy for the treatment of HS with the opportunity to change the current standard-of-care.
The two Phase III studies, STOP HS1 and STOP HS2 are enrolling quite well given the strong Phase II data and the limited number of effective treatment options. We anticipate Phase III data in early 2025 with a potential launch in 2026. Ruxolitinib cream and povorcitinib, we believe we will be the only company to potentially provide both the topical and oral option for a number of indications, expanding their armamentarium of effective therapies for certain conditions, including HS, vitiligo, and prurigo nodularis.
Moving to slide 20 and our two newest IAI programs. We are pleased to have closed the Escient transaction and now add two mass-related G-protein coupled receptor antagonists or MRGPRs, to our pipeline with significant potential in multiple indications. MRGPR antagonism is a specific novel mechanism for blocking mast cell activation independent from IgE and has been a high priority target to our IAI pipeline as a paradigm-changing therapeutic approach. Mast cells play a central role in initiation and perpetuation of inflammatory responses and their dysregulation can contribute to the development and progression of many inflammatory diseases.
262 is a first-in-class medicine, which entered the clinic in January 2023 and is currently being evaluated in three proof-of-concept clinical studies. By blocking the activation of mast cells, 262 holds great promise across a broad range of mast cell-mediated diseases as a once-daily oral treatment, potentially devoid of the side effects observed with other therapies. As a reminder, in a Phase I Healthy Volunteer Study, 262 was well tolerated at low interpatient PK variability and achieved exposures well above predicted efficacious levels. We believe the excellent safety profile along with the potential for compelling efficacy could be a key differentiator for this program.
262 is currently in a Phase 1b open-label study in chronic-inducible urticaria or CIndU and in a randomized Phase II study in chronic spontaneous urticaria or CSU with data for the studies expected during the first quarter 2025. Marked by painful and pruritic hives, CIndU and CSU are currently treated with antihistamines, but nearly 50% of patients do not experience symptom control, which can lead to anxiety, depression, and inability to work and social isolation, underscoring the need for safe and effective oral therapeutic options.
262 is also currently being evaluated in a randomized Phase II study in atopic dermatitis, and data for this study is also expected during the first quarter of 2025. There is continued need for additional safe and effective oral treatment options in AD, and we believe success in this indication could further build on our leadership in AD.
547 is a highly selective antagonist of MRGPRX4, a cell surface receptor expressed on neurons in the dorsal root ganglia that is activated by bile acids, bilirubin, and other heme metabolites, and thought to be a key mediator of the often intense unrelenting pruritus experienced by patients with cholestatic liver disease. 547 has the potential to become the first targeted therapy for Cholestatic pruritus, lacking the side effects observed with other approaches. A randomized double-blind study has been conducted in patients with Cholestatic pruritus due to primary biliary cirrhosis or PBC, or primary sclerosing cholangitis, or PSC, with clinical proof-of-concept anticipated also during the first quarter of 2025.
Moving to MPNs and graft-versus-host disease on slide 24, we highlight there a number of ongoing programs where we have the goal of developing new transformative therapeutic options to build upon the significant impact Jakafi has had on patients. For our BET inhibitor, dose escalation is ongoing, both as monotherapy and in combination with ruxolitinib. And we have reported reductions in spring length and volume, as well as improvements in both symptoms and hemoglobin, suggesting this is an active compound. We plan to advance this program into Phase III development and expect to provide an update later this year.
For zilurgisertib, our ALK-2 inhibitor, we have observed early signals of clinical activity in patients with myelofibrosis through hepacyte reduction in monotherapy and in combination with ruxolitinib. Zilurgisertib was well tolerated with a favorable safety profile and continuous dose escalation. We plan to provide an update later this year.
As previously disclosed, we submitted a BLA for axatilimab for the treatment of third line chronic graft-versus-host disease late last year based on a positive randomized Phase II study. In February, the filing was accepted for prior review, and we anticipate an FDA decision in late August. We are excited by the possibility of bringing a new treatment option to patients with this devastating complication of hematopoietic stem cell transplant. Additionally, we anticipate initiating a Phase III trial in combination with steroids and a Phase II study in combination with ruxolitinib later this year.
Building on Jakafi, which is the foundational therapy for MF and PV, we are concentrated on improving outcomes in the near-term by combining Jakafi with other therapies, as well as through approaches that have disease-modifying potential and that can significantly expand the addressable patient population to more than 200,000 patients. Our novel first-in-class anti-mutant CALR targeted monoclonal antibody has the potential to eradicate the malignant clone in patients with mutant CALR positive MPNs and to significantly modify disease outcomes.
9A9 binds with high affinity to mutant CALR and inhibits oncogenesis in cells expressed in this oncoprotein and antagonizes CALR oncogenic function, resulting in selective inhibition of JAK-STAT signaling only in CALR mutated cells with no effect on normal cells. This selectivity results in the specific killing of tumor cells harboring the mutation and is suggestive of the potential to alter the cause of the disease in patients with CALR mutant MF and essential thrombocytopenia.
Mutant CALR mutations are present in approximately 25% to 35% of patients with MF and ET. The Phase I studies are currently enrolling, and we are in track to share data in 2025. As a reminder, the JAK2V617F mutation is the most common somatic mutation in MPNs and is present in 55%, 60%, and 95% of patients with MF, ET, and PV, respectively. Unlike ruxolitinib, which inhibits both wild-type and V617F mutation-positive cells, 058 selectively binds to the JAK2 JH2 site, disrupting the V617F-induced conformation and thus allowing selective inhibition of mutant activity in the JAK2 receptor, while sparing well type, making our JAK2-V617F inhibitor a potentially transformative therapy for patients with PV, MF, and ET. Data for this program is expected in 2025.
Moving to our oncology pipeline on slide 29. We continue to build a robust portfolio with increased emphasis on first-in-class and our best-in-class and novel immune oncology programs with the potential for large treatment effects. Tafasitamab, currently approved in combination with the lenalidomide for patients with relapse or refractory DLBCL is on track to deliver Phase III results in follicular lymphoma and marginal zone lymphoma later this year, with a potential approval in 2025.
All Phase III data for first-line DLBCL in combination with R2-CHOP is expected next year. Today, we unveiled positive top-line results on two pivotal Phase III retifanlimab programs. Retifanlimab met the primary endpoints in both the squamous cell anal carcinoma and non-small cell lung cancer Phase III studies. In non-small cell lung cancer, we saw a statistically significant and clinically meaningful improvement in overall survival. And squamous cell anal carcinoma, we observed a statistically significant and clinically meaningful improvement in progression-free survival.
Both studies show retifanlimab was generally well tolerated and no new safety signals were detected. Retifanlimab could represent the first ever PD-1 or PD-L1 antibody approved for the first line treatment of patients with SCAC. We believe that retifanlimab also has substantial strategic values in combination therapy without other programs in our pipeline, and we look forward to sharing the full results of these studies at an upcoming medical meeting later this year.
Additionally, we plan a meeting with regulatory agencies to determine next steps and look forward to providing additional clarity in the coming weeks and months. Our potentially first-in-class small molecule, CDK2 inhibitor, has shown evidence of clinical activity demonstrating partial responses or stable disease in patients with CCNE1 over-expressing tumors. We expect to share this data as well as the development plan at ESMO in September. We believe our CDK2 inhibitor could be a foundational therapy for patients with ovarian cancer, as well as other CCNE1 overexpressed tumor types.
KRAS mutations are one of the most common genetic abnormalities in cancer, especially lung, colon, and pancreatic cancers. Our potentially first-in-class, best-in-class KRAS G12D small molecule inhibitor, 734 is a potent, selective, and orally bioavailable KRAS-G12D inhibitor that has shown excellent efficacy in several preclinical models. With no currently approved G12D targeting agents, 734 could address an important patient need as a KRAS-D12D mutation is found in 40% of pancreatic ductal adenocarcinoma, 15% of colorectal cancers, and 5% of non-small cell lung cancers.
Our Phase I clinical trial is enrolling well, and we are on track to share initial data in 2025. The TGF-beta signaling pathway plays a complex role in cancer biology and progression with different functions in early and late-stage cancer cells. Early generation therapies have been unsuccessful due in large part to the toxicity associated with systemic pathway inhibition with our bispecific antibody inhibiting PD-1 and TGF-beta receptor to signaling on T cells.
We have precisely tuned the binding arms against PD-1 and TCF-beta receptor 2, which we believe will result in the complete inhibition of TGF-beta signaling without the unwanted on-target effects. Our TGF-beta receptor 2 by PD-1 bispecific antibody has the potential to target multiple immunosuppressive pathways across a number of cancers. And if successful, could represent a meaningful contributor to our growth. We expect to share data from the Phase I program in 2025.
In closing, this slide summarizes the considerable number of milestones across 2024 and 2025 that will continue the transformation of our pipeline with a strong focus on new molecular entities with the potential to make an indelible impact on patients.
With that, I would like to turn the call over to Christiana for the financial update.
Christiana Stamoulis
Thank you, Pablo, and good morning, everyone. Our second quarter results reflect strong commercial execution and continued growth with total revenues of $1.4 billion, up 9% versus the same period last year.
Total product revenues of $907 million in Q2 were driven by demand of Jakafi and Opzelura and increased revenue contribution from Monjuvi following our acquisition in February of the global exclusive rights to axatilimab. Total royalty revenues were $137 million, up 8% compared to the second quarter of 2023, driven by an acceleration in the demand for Jakafi.
Turning to Jakafi on slide 38. Jakafi net product revenues were $706 million for the second quarter. Net product revenues reflect continued demand growth with paid demand, up 9% year-over-year, driven by growth in PV, GVHD and MF. Year-over-year net sales growth was lower than the underlying demand growth due to higher channel inventory levels at the end of Q2 last year. At the end of Q2 2024, channel inventory was within normal range.
Turning now to Opzelura on slide 39. Net product revenues for the second quarter were $122 million, representing a 52% increase year-over-year, driven by growth in new patient starts and refills across both AD and vitiligo in the U.S. as well as continued contribution from the commercialization of Opzelura for vitiligo in Europe.
In the second quarter, Europe contributed $11 million of Opzelura net product revenues, driven by continued uptake in Germany and France. We expect contribution from Spain and Italy to start in Q3 with modest contribution in that quarter due to the impact of summer vacation in Europe.
Moving on to slide 14, our operating expenses on a GAAP basis. Total R&D expenses were $1.14 billion for the second quarter, reflecting the upfront consideration paid for the acquisition of Escient Pharmaceuticals. Excluding the impact of the upfront consideration related to Escient and other upfront and milestone payments, total R&D expenses were $692 million, representing a 13% increase year-over-year, due to continued investment in our late-stage development assets, the assumption of MorphoSys share of tafasitamab development costs and the timing of certain expenses.
Total SG&A expenses were $306 million for the second quarter, representing an 8% year-over-year increase primarily driven by $22 million of expense related to accelerated vesting for certain Escient stock awards and severance payments in connection with the acquisition of the company.
Excluding the impact of the upfront consideration related to the acquisition of Escient, SG&A expenses were flat year-over-year. Excluding the impact of upfront consideration and milestone payments, in Q2 and in the first-half of the year, total OpEx grew 8% and 5%, respectively, which is below the 9% growth in total revenues, indicating continued improvement in operating margins.
Turning to Slide 41. As previously discussed, in May, we completed the acquisition of Escient Pharmaceuticals for total consideration of $783 million, including Escient's net cash on the balance sheet at close. The allocation of the total consideration resulted in a onetime expense of $691 million recorded under R&D expense and $20 million recorded under G&A expense. The remaining balance was allocated to certain assets and liabilities on the balance sheet.
During June, we completed a $2 billion share repurchase program, reflecting our confidence in the future outlook of the business, the strength of our commercial product portfolio and the clinical development pipeline. In total, we repurchased and canceled approximately 33.3 million shares of our common stock, representing 14.8% of our total outstanding shares of common stock for $60 per share. The share repurchase resulted in a reduction in our cash balance and corresponding decrease to shareholders' equity.
Moving on to our guidance for 2024. As a result of Jakafi's continued strong performance in the first half of the year, we are raising the low end of our Jakafi guidance from $2.69 million to $2.71 billion. For Opzelura, we expect continued growth in the second half of the year with the typical dermatology product seasonality reflected in Q3 demand in net product sales as a result of a lower number of patient visits during the summer vacation month.
Moving to R&D guidance as a result of the acquisition of Asian, we are updating our guidance for R&D expense excluding the impact of the upfront consideration paid to a new range of $1.76 billion to $1.8 billion. While our strategic review of our clinical portfolio and decision to discontinue select programs does not have an impact on R&D expenses in two it creates room to aggressively pursue and invest in the development of our priority assets, and at the same time, control the future growth of R&D expenses.
Finally, we are reiterating our full year 2024 guidance for other hematology/oncology products, COGS and SG&A.
Operator, that concludes our prepared remarks. Please give your instructions and open the call to Q&A.
Question-and-Answer Session
Operator
Certainly, we'll now be conducting a question-and-answer session. [Operator Instructions] Our first question today 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 and congrats on the quarter. I have a question about the pipeline restructuring. Can you drill a little bit more into the key determinants of the pipeline restructuring? For instance, two questions. One is on the oral PD-L1, you had seen data, you had multiple candidates. How much did the retifanlimab data that you have from the Phase III trials recently impact this decision? Thank you. I'll get back in queue.
Pablo Cagnoni
Yes. Thank you for the question. This is Pablo. The retifanlimab data did not have an impact on the pipeline restructuring. As I mentioned in my prepared remarks, the restructuring was driven primarily by two things. One, data review of the existing programs, the programs that we terminated, PDR, PD-L1, TIM-3, LAG-3 and the bispecific LAG-3 as well as a continued progression and promising data that we're seeing from the earlier-stage pipeline that is now becoming mid-stage and we'll start delivering important milestones in the next 18 months. So it was unrelated to the retifanlimab pivotal phase results. We are excited about those results, particularly the anal cancer data that we think, as I mentioned in my prepared remarks, could potentially represent the first PD-1 antibody for previously untreated squamous cell anal cancer.
Operator
Thank you. Next question today is coming from Michael Schmidt from Guggenheim Partners. Your line is now live.
Paul Jeng
Hi, this is Paul Jeng on for Michael. Thanks for taking our question. Are just on Jakafi, and if you could comment on some recent trends. I know you mentioned PV and GVHD as key drivers, but what are your go-forward expectations for Jakafi share in myelofibrosis, specifically in new patients in the frontline setting. You mentioned some minimal impact from competitors. Would you expect that to remain the case going into the second-half of the year and beyond? Thank you.
Barry Flannelly
Hi, Paul, it's Barry. Thanks for the question. So our -- so as Herve said, in fact, we're growing. It totaled patients for MF quarter-over-quarter year-over-year. were up 2%. And in fact, new patients in the quarter for MF were up more than that. In fact, we continue to see growth of MF by PV and GVHD are really the main growth drivers, if you're asking about the competition, in fact, we think those drugs pacritinib and momelotinib are being used in the second-line setting for the most part.
Operator
Thank you. Next question is coming from Brian Abrahams from RBC Capital Markets. Your line is now live.
Brian Abrahams
Hey, guys. Good morning. Thanks for taking my question, and congrats on the continued progress with both operationally and commercially with the pipeline. I guess speaking of the pipeline, as we look towards ESMO in the CDK2, I was wondering if you could talk a little bit more about, I guess, what we should be looking for I guess, how definitive of data set you expect to have in terms of patient numbers at the go-forward dose?
And what you're hoping to show to be optimally and over time to be optimally impactful and competitive in ovarian and also to potentially expand into breast cancer and other indications, which may be more competitive. Thanks.
Pablo Cagnoni
Certainly, so we look forward to updating on the progress of our CDK2 program at ESMO in a couple of months. As I've mentioned in my prepared remarks, our focus initially is ovarian cancer. That doesn't mean we're not doing work in other tumor types and not the CCNE1 overexpressing tumor ties but the focus of this initial update will be ovarian cancer. And what we expect to show during the ESMO presentation is data set that captures the dose escalation.
We just had a range of doses with our CDK2 inhibitor and different schedules as well. and we'll provide data that we believe supports the case to continue the development of CDK2 inhibitor in patients with ovarian cancer and will provide as well as the data update, a development path for this product for this molecule in patients with ovarian cancer going forward. So it will be data update. We have a range of doses, different schedules and the data supports further development and we'll show you a development plan as well.
Operator
Thank you. Next question is coming from Vikram Purohit from Morgan Stanley. Your line is now live.
Vikram Purohit
Hi. Good morning. Thank you for taking our question. We had one on LIMBER. So for the ALK2 inhibitor data expected in the second-half of the year, could you walk us through what your expectations are in terms of the volume of data we may get, the amount of follow-up and what you're setting is the threshold for deciding on next steps for the program? Thank you.
Steven Stein
Yes, hi, it's Steven, taking your question. So you know, in terms of its mechanism of action, it's inhibit hepcidin, which then helps in terms of iron release and hemoglobin production. We've shown in prior data sets that as we increase dose, we get increase in hepcidin inhibition with some variation in the hemoglobin response, which is why we've continued to dose escalate because we've had more room to do so.
In terms of treating myelofibrosis, there's both disease-related anemia as well as potentially drug-induced anemia from suppression of cytokines like erythropoietin. So the idea is to try and attend to both of those and improve patients getting anemia either from the disease or from the drug, and we'll continue to escalate. And we'll show more patients with more data at higher doses and then potentially look at are there development path there that will be potentially addressable by the compound in those settings by alleviating anemia from the disease and the drug. So it's just -- it's an updated data set at higher doses.
Operator
Thank you. Next question is coming from David Lebowitz from Citi. Your line is now live.
David Lebowitz
Thank you very much for taking my question. Could you comment on the demand for PV at this point going into next year? How much impact is IRA had to this point in the numbers?
Barry Flannelly
Hi, thanks for the question. It’s Barry. So PV, we believe, actually is growing because of the efficacy of the product and the disease. And in fact, the most recent data from MAJIC-PV showed that long-term efficacy for Jakafi for those patients is quite good. And we believe that, that has spurred the uptake of PV and of Jakafi and PV patients.
Obviously, the IRA and the elimination of catastrophic what patients have to pay in the catastrophic coverage area, helps all patients, helps all patients who are on particularly oral chemotherapy drugs. So we're excited about that. We're glad that that's finally happened. And next year, 2025 will even be better when out-of-pocket for patients on Medicare Part D will only be $2,000. So the growth really is coming from the efficacy of the product, and we're glad that changes happen to Medicare Part D to make all oncology drugs more affordable for patients.
Operator
Thank you. Next question is coming from Eric Schmidt from Cantor Fitzgerald. Your line is now live.
Eric Schmidt
Thanks for taking my question. It's on R&D spend and the portfolio prioritization. I guess, on the one hand, you've cut some programs and on the other hand, you're ticking up your R&D guidance for 2024. I presume that's in part because of the Escient acquisition. But when you think kind of big picture and strategically around how much a company like Incyte should be investing in R&D. I do think you're still the industry high in terms of R&D as a percent of sales. What is your sort of solution to what a proper investment is in R&D at this stage?
Herve Hoppenot
Eric, thank you for -- Herve here. Thank you for the question because it's obviously something that has been sort of driving a lot of our thinking in the past few months. I mean, our first approach to R&D spending is a project-specific financial rationale. So if you take any of these projects that Pablo went through and there are 12 NCIs there, you can look at does it make sense to develop it?
Is that an investment that is reasonable for a product of this type. And you can go through the list from 12D to TGF beta, two, obviously, 617F and CALR and each of the project is first submitted to that test of saying, does it make sense, independently from the rest of the portfolio to develop this product. And obviously, we came to that conclusion for the projects that are moving forward and either because of certain data or because of the competitive situation, we came to the opposite conclusion for some of the projects in -- that we listed today. So that's the first thing.
And then the second one is that something that Incyte can do by ourselves or should we look for other sources of financing for this project or partnering if we believe that it's something that we cannot do by ourself. And that's where we came with this list of projects where by stopping some of them, we are creating room for the new project. We are also seeing some of the historical projects coming to an end, like retifanlimab and like we will see a decrease of the investment in tafasitamab over the next few months as we are finishing the follicular study and the next year will be the end of the first-line study.
So there is a movement where some projects are decreasing. Some projects are being stopped. And all of that is creating room to, as was described by Christiana, basically maintain a reasonable R&D spend in -- with improving ratios. And what Christiana just said is, as you see, the evolution of the P&L, we have been consistently improving the ratios with a decreasing percentage of revenue in R&D and in SG&A. So that's a big picture. It's going to happen at a pace that is over the next few years. It's not like a one-time event where suddenly, there is a big change in the number.
But a lot of the spirit of what was described today is prioritized resources to high potential program in the pipeline. And I hope you could see from Pablo's discussion that there are a number of them and at the same time, stop programs where we are not in a good competitive position or the data is not confirming what we were expecting at the beginning of the program.

Hi, good morning. For the LAG-3 assets, was it lack of differentiation from an existing asset that list discontinuation? Any color on what you saw or did not see from the LAG-3 would be helpful. Thank you.
Pablo Cagnoni
Yes. Thank you for the question. The most important point, I think, for the LAG-3 programs, both the monoclonal antibody and the bispecific was the competitive landscape, quite honestly. We are behind in both cases, far behind our competitors. There's a like three, obviously a proven combination with PD-1. And there's at least one bispecific LAG-3 that is well ahead of us already randomized trials. So that was the main determinant. And when it comes to data, we'll decide what is the right time and setting to disclose some of the data that we've seen with those programs.

Thank you. Next question today is coming from Jessica Fye from JPMorgan Chase. Your line is now live.
Jessica Fye
Thanks for taking my question. Looking ahead to the proof-of-concept data for the MRGPRX4 antagonist and PBC and PSC coming up next year. Should we think about the data shared by Mirum in PBC as a potential benchmark you'd like to meet I think they showed around a 2.3 point placebo-adjusted difference on the adult daily ICHRA score in PBC?
And then if I could think in a bigger picture one, just for Pablo now that you've been at Incyte for about a year and have had some time to get to know the pipeline better. Where do you think investors should spend more time? And what do you think will be the company's most important pipeline assets if we look out, say, three years from now? Thanks.
Pablo Cagnoni
I think we are excited about that program, particularly in the continuous need for better pruritus control in patients with PBC and PSC, particularly PSC, there's really no good alternatives out there that have been approved. So the benchmark for Mirum is a reasonable place to start. One of the things we like about both X2 and X4, by the way, about 262 and 547 is the great safety profile we've seen so far. So stay tuned. We'll provide an update early next year.
When it comes to the second part of your question, if you look at slide 14, and it's hard to pick favorites from that slide, I think that I am very excited about some of the programs in our earlier pipeline. I think that if you go vertical by vertical, I think obviously, the acquisition of Escient with both the X2 and the X4 antagonists, those are potential both first-in-class programs that address a number of potential indications. I think in oncology, the near-term CDK2 data reveal is something that we're very excited about. And I think that when you look at our TGF data receptor by PD-1 bispecific, we have taken a unique approach to those two pathways that we think could be a big differentiator.
And MPNs, of course, I have to mention our mutant color and 617 programs, both of which are not just first-in-class, but they're a unique way to address patients with MPNs and potentially change disease outcomes by changing the natural history of the disease. So I think those are the areas where I would say today, we have the most excitement inside the company. And I would add by investigators outside the company that is showing by how quickly some of the studies are accruing.

Thank you. Next question today is coming from Jay Olson from Oppenheimer & Company. Your line is now live.
Jay Olson
Oh, hey, congrats on the quarter and thanks for taking the question. There are some recent publications showing synergistic efficacy from combining JAK inhibitors with PD-1 antibodies. Can you please share your takeaways from those publications? And does Incyte have plans to develop a JAK inhibitor, such as povorcitinib in combination with PD-1 antibodies for oncology? Thank you.
Steven Stein
Yes, Jay, it's Steven. Thanks for the question. There were two simultaneous publications that were intriguing showing that potentially JAK inhibition can modulate the T cell environment in a positive way and enhanced checkpoint inhibition. However, our own experience in the past has not been as successful clinically.
So I don't think if you remember, but years ago, we tried JAK inhibition on its own in several solid tumors based on an inflammatory hypothesis with C-reactive protein. And unfortunately, those endeavors were negative -- we also did some work in investigating initiated work in combination with PD-1 with JAK inhibitors, although we didn't have clinical data, some of the translational data didn't show the right directional changes in T cells. But you are correct in that those two simultaneous papers has reignited some interest, and we'll relook at it. But no current R&D sponsored plans there.

Thank you. Next question is coming from Evan Seigerman from BMO Capital Markets. Your line is now live.
Evan Seigerman
Hi, guys. Thank you so much for taking my questions today. With your recently completed the large care share repurchase how much capacity do you have left for further business development? And maybe walk us through some of the rationale of doing such a large-scale share repurchase versus, say, doing a larger acquisition to bolster the pipeline?
Christiana Stamoulis
Evan, it's Christiana. So first of all, the share repurchase that we did reflect the confidence that we have in the outlook of the business, both driven by the progress on the commercial front, but also very much so by the evolving pipeline and all the excitement behind the programs that Pablo discussed.
So we saw a very big disconnect between the long-term value that we see in the company versus what has been reflected in the stock price, that the decision to do the share repurchase. The size of the share purchase was enabled by the fact that we have a very strong balance sheet, and we are in a position to both do big repurchase and at the same time, retain financial flexibility for more BD if we choose to do so.
So we ended the quarter with $1.5 million in cash. We don't have any debt, which gives us additional firepower to be able to pursue if we decide to do so. As you saw today, we have a very exciting pipeline, so there is a lot of focus on moving forward our internal programs, but we are in a position to opportunistically bring in additional opportunities if we believe these are opportunities where we can add value.

Unidentified Analyst
Hi, this is Alex on for Mark. Thanks so much for taking my question. For Opzelura, could you quantify the impact of the preferred formulary placements you achieved for 2024? And do you view these contracts as having been successful so far? And would you maybe expect to negotiate any additional deals for the 2025 plan year?
Matteo Trotta
Hi, Alex, it's Matteo here. Yes, so the preferred position that we gained this year in CBS was one of the key contributors to the absolute growth that we are experiencing this year. In addition to that, obviously, we're seeing patients on CBS benefit from an easier and improved accessibility to Opzelura and it gives also Incyte the opportunity to better execute the support programs that we have in place for all the commercial eligible patients.
In terms of expecting for the future, we have a plan for 2025, which we are executing while we speak. We'll continue to bring up some new data that we have very interesting from a PBM and [PEO] (ph) perspective, the real world evidence of Opzelura. And we expect that we continue to improve our access going forward and utilization management wherever it's feasible and possible. We're always keeping in mind that every step we take in that direction will have to be improving our net sales line.

Thank you. Next question is coming from Reni Benjamin from Citizens JMP. Your line is now live.
Reni Benjamin
Hey guys, thanks for taking the questions. I guess I'd love to get your latest thoughts on tafasitamab now that you've acquired the rights to that asset. Kind of how you're thinking about it and what the market opportunity is for frontline as well as follicular in MCL, especially given everything that you've learned from the relapsed/refractory DLBCL market and kind of the challenges there? Thanks.
Herve Hoppenot
I think -- maybe I can start, and Barry can speak in more detail. I mean the picture on tafasitamab, obviously, was -- the financial picture of tafasitamab was changed when we basically got for free the full rights for the product. I mean that was a transaction at the beginning of the year, where it puts us now is facing the two Phase III studies that we have ongoing. We will have very soon in the next few weeks, the result of the follicular lymphoma, assuming if it's positive, it would obviously give us an opportunity. It's not enormous in size, it's fairly competitive, but there is a lot of upside for the brand at the stage where we are on this new indication, it would be a large randomized study. So it will add to the clinical profile of the product across all indications. So that's the first step.
And then there is a first line coming in 2025, where if positive and depending on the size of the benefit that is observed could have a larger potential for the brand. I think the positioning of Monjuvi and Minjuvi in Europe and the U.S. is really driven by the fact that the efficacy that you see is at a very low cost in terms of safety side effect. So that's the ratio of efficacy safety that we observed with Monjuvi is very unique, compared to the rest of the competition. And it has a space that I think will -- depending on the data that we see will be important. It's not going to be a brand that is in the multibillion range, but it's going to be a brand that can increase by a few hundred millions, and I think it will be a good contribution to the portfolio.
Barry Flannelly
Yes. I mean, everybody really said it all, but we are excited about follicular and marginal zone. There's combined, there's about 12,500 patients that are treated in those settings in the second line plus setting. So yes, it's competitive, but particularly for follicular lymphoma. R-squared is currently the market leader in the second line setting in follicular lymphoma and obviously, adding tafa to it, we hope to improve the outcome for patients. And in the first-line setting for disease large B-cell lymphoma when we have that data next year and hopefully, the addition of tafa to R-CHOP will actually improve the lives of patients.
In fact, we're hoping to obviously improve cure rates, and there's 30,000 patients in our frontline diffuse large B-cell lymphoma patients. And then our study is really concentrating on IPI 3 and higher. So anyway, so the opportunity for us is there as long as the data is what we hope it to be. I think we'll have success, as Herve said, but in both situations, diffuse like B-cell lymphoma and in indolent lymphoma, it's a very competitive market, but we think we have a profile of the drug that physicians and patients will want to use.

Thank you. Next question is coming from Kelly Shi from Jefferies. Your line is now live.
Unidentified Analyst
Hi, god morning. This is Clare on for Kelly. Thanks for taking our questions and congrats on the quarter. So just a quick one on Opzelura. Could you help us understand the growth in that trend during the quarter? And how should we think about it in the upcoming quarter? And what's the kind of latest mix you're seeing between atopic dermatitis and vitiligo how are you thinking about the pediatric uptick in 2025?
Christiana Stamoulis
Let me take the first part of the question regarding Opzelura and gross to net. So gross to net in Q2 was broadly in line with where we were last Q2. So the growth really was driven by demand here. In terms of going forward, as we have discussed in the past, we are not focusing on gross to net in isolation, but on net sales. And that is where the focus is. if there are situations where we believe that there is an opportunity to improve positioning to improve access by giving some additional discount, and that would lead to disproportionate increase in demand, and therefore, net sales, we are going to pursue it. But looking at gross net in isolation is not something that we will be doing and providing a separate forward guidance for gross to net.
Matteo Trotta
Yes. And I can take the other two pieces, Matteo here. One is the split between atopic dermatitis and non-segmental vitiligo, which is currently 60-40. And it's a great indication for us because when we see the split being consistent, the growth is coming from both indications, and then the third piece of your question, I believe, was on the sizing the potential of the pediatric indication. We see definitely the one -- the potential label expansion of Opzelura for patients 12 to 11 years old in atopic dermatitis a driver of continuous growth.
The patient population is quite sizable. We see 2 million patients with AD in the age range and mostly treated with TCIs and TCS today. So a great opportunity for us and in terms of sizing, we see the contribution to our total AD business in the future from pediatric indication in the range of 10%, 15% of their business, which is fairly in line with what we see from other therapies in the same space for the same age range.

Thank you. Next question today is coming from Andrew Berens from [Leerink Partners] (ph). Your line is now live.
Andrew Berens
Hi, thanks, and it's Leerink Partners. We're glad to have moved beyond that stage of our existence. But a couple of questions. I was wondering if you can give us some color on the Jakafi XR program, it seems as if you could have the PK/PD data this year? And should we plan on getting an update ahead of the stability data? And then for the CALR and JAK2 selective programs. I know it's early, but what do you think a pivotal program would look like? Would the endpoints be similar to Jakafi with SVR35 rates? And would you have to compare the Jakafi head-to-head? Or would you start in later stages of the disease and move forward? Thanks for taking my questions.
Steven Stein
Hey, Andy. It’s Steven, thanks for your question. On Jakafi XR, as Pablo had in his slides, he pointed to the pivotal BE data, the bioequivalence data come in, in the early part of 2025 next year. And then as the stability delivers towards the sort of third quarter, that's when we would file that indication should everything be directionally correct and then get an approval in 2026. So that's within what we said we would deliver for XR and we await that pivotal BE data for which the study is starting very soon.
For CALR and V617F, again, to expand on Pablo's comments, it's still early days with both programs, obviously, in dose escalation with enormous promise in terms of a totally new mindset around disease modification dash potentially cure, because of eradication of the malignant clone. And in those entities, I mean, it's still early days, we'd have to discuss with regulators is they are completely another way of viewing the diseases and not look at the traditional JAK inhibition pathway for SVR35 and total symptom score in terms of eradicating the clone and removing the malignancy and the associated morbidity from it, there are potentially other regulatory pathways, which we'll explore at that time. So thank you for bringing it up because it could be a completely new way of thinking about those entities.

Thank you. Our next question is coming from Gavin Clark-Gartner from Evercore ISI. Your line is now live.
Gavin Clark-Gartner
Hey, guys. I just wanted to ask another question about tafasitamab. What are your latest thoughts on developing in autoimmune diseases? And how are you making that decision? Thanks.
Pablo Cagnoni
Yes. Thank you for the question. So look, as Herve mentioned, when we acquired full rights for tafacitamab early this year and knowing that we have a near-term pivotal readout as well as another one next year, led us to rethink a little bit about whether the level of investment in that program is adequate. And quite honestly, we're in the middle of that process.
We're obviously aware of all the data with CD19 targeted therapies in autoimmune disease. We're conducting a full evaluation as well as interactions with external scientists to really understand, a, what's the opportunity for taf at this point in AI from the mechanistic point of view. What's the competitive landscape? What does it look like? And what are the remaining opportunities that we can go after with a reasonable and prudent level of investment. So we're doing that evaluation literally as we speak. We'll have an update probably on that later this year.

Thank you. Our final question today is coming from Salveen Richter from Goldman Sachs. Your line is now live.
Salveen Richter
Good morning. Thank you for taking my question. On the back of the portfolio prioritization and the Escient acquisition, do you feel comfortable at the current time that you can offset Jakafi LOEs and grow beyond as well? Thank you.
Herve Hoppenot
Thank you, Salveen. Maybe I'll take that. I mean it's obviously the world purpose of our investment in R&D is to more than compensate for what could be the expiration of the current product. So you can look at the size -- I mean, the guidance we have on Jakafi that has been there for a number of years is around $3 billion by -- as peak sales. So we are way very much on the way to get there. And when you look at the number of projects, we are speaking of 10 launches in the next few years.
We are speaking of 12 NCEs that we have in development. I mean, that would be each of them with the potential that is meaningful, that would be certainly way more than what we need to just compensate for Jakafi. So the view and obviously, it will depend on the clinical success we have with this project. But the view is that today, our portfolio is very much giving us a growth profile that goes beyond the Jakafi patent exploration.
