Mirum and Incyte to Present Zilurgisertib Study Results at ENDO 2026
Mirum Pharmaceuticals (MIRM) and Incyte (INCY) announced that Phase 2 results from the PROGRESS study evaluating zilurgisertib, an investigational ALK2 inhibitor, in patients with fibrodysplasia ossificans progressiva will be presented at ENDO 2026, the Endocrine Society's annual meeting, taking place June 13-16, 2026, in Chicago, Illinois. "ENDO 2026 is an important milestone for the zilurgisertib FOP program as we share pivotal results from the PROGRESS study in patients living with this debilitating disease," said Steven Stein, M.D., Executive Vice President, Chief Medical Officer and Head of Late-stage Development at Incyte. "These data add to the growing clinical understanding of zilurgisertib's potential in FOP as Incyte and Mirum continue to advance toward the FDA's Priority Review PDUFA date of September 26, 2026."

About the author

- Acquisition Agreement: Incyte has entered into a definitive agreement to acquire Vega Therapeutics, a wholly owned subsidiary of Star Therapeutics, for $1.25 billion, with total potential consideration reaching $2 billion contingent on sales milestones, indicating Incyte's strategic intent to expand its hematology portfolio.
- New Drug Addition: The acquisition will add VGA039, a novel monoclonal antibody, to Incyte's hematology portfolio, which has the potential to treat various bleeding disorders, particularly all types of von Willebrand disease, thereby enhancing its competitive position in the market.
- Clinical Advancement: VGA039 is currently in a Phase 3 study designed to assess the safety and efficacy of subcutaneous administration for bleeding prophylaxis in patients with all types of von Willebrand disease, having received multiple FDA designations including fast track and breakthrough therapy, indicating a promising development outlook.
- Strategic Fit: Incyte CEO Bill Meury stated that VGA039 aligns with the company's strategy to build a top-tier growth company for the future, as it is a first-in-class Phase 3 asset with compelling early data and a manageable development path, expected to become a significant growth driver in its core therapeutic area of hematology.
- Acquisition Overview: Incyte Corp. is nearing a $2 billion acquisition of Star Therapeutics, with approximately $1.25 billion in upfront cash and an additional $750 million tied to future performance, expected to be announced on Monday, reflecting a trend among midsized drugmakers to enhance their product pipelines through acquisitions.
- Therapeutic Potential: This acquisition will provide Incyte access to Star's lead experimental treatment VGA039 for von Willebrand disease, the most common inherited bleeding disorder, which is in late-stage clinical testing and has received Fast Track designation from the FDA, potentially accelerating the convenience of treatment options for patients.
- Market Opportunity: While around 35,000 patients have been treated for von Willebrand disease at U.S. hemophilia centers in recent years, industry analysts believe the potential patient population is significantly larger, indicating a substantial market opportunity, with Incyte's expertise in blood disorders aiding in commercialization efforts.
- CEO Strategic Direction: This transaction marks the first major deal under CEO Bill Meury, who has emphasized acquisitions as a strategy to offset future revenue pressures from the expected 2028 patent expiration of the company's top-selling drug Jakafi, reflecting a broader trend of consolidation in the biotechnology sector.
- ETF Decline: The Global X Uranium ETF fell approximately 5.7% during Wednesday afternoon trading, indicating weak market sentiment towards uranium-related assets, which could negatively impact investor confidence and lead to capital outflows.
- Weak Individual Stocks: Within the ETF, shares of Nano Nuclear Energy dropped about 15.4%, while Nuscale Power fell approximately 12.7%, reflecting a pessimistic outlook on these companies' prospects, potentially affecting their financing and development plans.
- Increased Market Volatility: The decline of the uranium ETF, combined with overall market fluctuations, may prompt investors to reassess their investment strategies in the nuclear energy sector, thereby impacting the stock performance of related companies.
- Shifting Investor Sentiment: Given the poor performance of the uranium ETF, investors might shift towards other more attractive investment options, which could negatively affect the long-term growth potential of the uranium industry.
- Clinical Trial Success: Incyte's Monjuvi, developed in collaboration with Xencor, demonstrated a 25% improvement in cancer-free survival in the Phase 3 frontMIND trial, providing a new treatment option for high-risk diffuse large B-cell lymphoma patients.
- Significant Treatment Effect: Compared to the standard R-CHOP regimen, Monjuvi combined with R-CHOP and enalidomide reduces the risk of disease progression or death by 25%, indicating its substantial potential in improving patient outcomes.
- Urgent Market Demand: Despite R-CHOP being the standard first-line therapy, nearly 40% of patients experience disease progression or relapse after initial treatment, highlighting the necessity and demand for innovative therapies in this space.
- Regulatory Application Prospects: Incyte plans to leverage existing frontMIND data to support global regulatory submissions seeking to incorporate Monjuvi and enalidomide into R-CHOP for newly diagnosed DLBCL cases, further expanding its market share.
- Significant Efficacy Improvement: The frontMIND study demonstrated that the Tafa-Len-R-CHOP treatment group achieved a 25% reduction in the risk of disease progression compared to the R-CHOP group (HR 0.75), indicating a clinically meaningful benefit for high-risk lymphoma patients.
- Long-term Survival Rate Enhancement: With a follow-up of 2 and 3 years, the Tafa-Len-R-CHOP group showed an 8.2% and 6.6% increase in progression-free survival (PFS), respectively, providing new hope for previously untreated high-risk diffuse large B-cell lymphoma patients and potentially changing the current treatment standard.
- Good Safety Profile: Although the incidence of Grade 3 adverse events was higher in the Tafa-Len-R-CHOP group at 86.7% compared to 76.1% in the R-CHOP group, the overall safety was consistent with expectations and did not interfere with treatment continuity, demonstrating the acceptability of the new therapy.
- Support for Global Regulatory Applications: The data from the frontMIND study will support global regulatory applications for Tafa-Len-R-CHOP, marking the therapy's potential to become a new standard of care for high-risk lymphoma patients, addressing the urgent market need for innovative treatments.
- Partnership Expansion: Incyte and Genesis Molecular AI announced the expansion of their AI drug discovery partnership, leveraging Genesis' GEMS platform to accelerate the development of new small-molecule medicines, highlighting their deep collaboration potential in innovative drug development.
- Financial Commitment: Under the agreement, Incyte will share its proprietary experimental data to train Genesis' AI models, with Genesis receiving a total of $120 million, including $80 million in upfront cash and $40 million in equity investment, ensuring ongoing research and development funding.
- New Drug Targets: The collaboration adds at least five new drug targets, granting Incyte exclusive rights to develop and commercialize any resulting drug products, indicating a strategic advantage in new drug development.
- Potential Earnings: Genesis can earn up to $232 million per program in milestone payments, with total potential value exceeding $1 billion, along with royalties on future approved drugs, showcasing the long-term profitability potential of this partnership.
