Disc Medicine在2026年关键数据发布之前加速贫血和血液疾病的后期试验，利用FDA支持的Bitopertin和扩大铁监管管道实现2025-2026年里程碑

Disc Medicine, Inc. (NASDAQ:IRON), a clinical-stage biopharmaceutical company focused on the discovery, development, and commercialization of novel treatments for patients suffering from serious hematologic diseases, today outlined its recent pipeline and operational progress and strategic priorities for the rest of 2025 and 2026.

"2025 has been another eventful year for Disc Medicine, and we are accelerating development across three key indications—EPP and our myeloproliferative neoplasm portfolio, MF and PV. For bitopertin, with the recent grant of the FDA's CNPV, our focus is on accelerating our commercial readiness to ensure access to patients as quickly as possible upon approval, if granted," said John Quisel, J.D., Ph.D., Chief Executive Officer and President of Disc Medicine.

"We're also excited about the progress across our iron homeostasis portfolio, DISC-0974 and DISC-3405, as these programs will be important drivers of Disc's future growth. We're positioning DISC-0974 for development in anemia of MF and look forward to providing an initial set of data from the Phase 2 RALLY-MF trial of DISC-0974 in its lead indication, anemia of MF, by the end of this year. Additionally, we are advancing the development of DISC-3405 in PV with data expected next year. We also continue to drive our expansion strategy for both of these programs with a plan to initiate a Phase 2 trial of DISC-0974 in anemia of inflammatory bowel disease in 2026 and a Phase 1b trial of DISC-3405 in sickle cell disease by year end."

Key Near-Term Business Objectives

Bitopertin: GlyT1 Inhibitor (Heme Synthesis Modulator)

• Accelerate activities to support a potential US approval and launch in late 2025 or early 2026 based on accelerated review timeline associated with receipt of the CNPV, which is designed to shorten the NDA review process to 1-2 months
• Drive enrollment of ongoing APOLLO confirmatory trial of bitopertin in EPP that is intended to also support potential approval of bitopertin in territories outside the US

DISC-0974: Anti-hemojuvelin Antibody (Hepcidin Suppression)

• Progress and position DISC-0974 to be advanced into potential late-stage clinical development for anemia of MF
• Initial data from ongoing Phase 2 study in anemia of MF to be reported by year end; topline data expected in 2026, if positive, is anticipated to support discussion with regulatory agencies on registrational path
• Demonstrate role of hepcidin suppression and anti-hemojuvelin (HJV) mechanism in other anemias of chronic disease:
  • Recently completed Phase 1b double-blind, placebo-controlled study of DISC-0974 demonstrated engagement of mechanism in anemia of non-dialysis dependent chronic kidney disease (NDD-CKD) with variable effects on hemoglobin
    • DISC-0974 was generally well-tolerated with substantial decreases in hepcidin, increases in iron, and improvements in markers of erythropoiesis
    • Meaningful hemoglobin increases observed in only a subset of patients were in part driven by those with higher baseline erythropoietin (EPO) levels
    • Full data will be shared at the upcoming 2025 ASN Kidney Week; we are assessing options for the program based on full analysis of the data
  • Initiation of a Phase 2 study in patients with IBD and anemia anticipated in Q1 2026, and planning exploratory studies in additional patient populations with anemia of chronic disease.
• Plans to accelerate next-generation, long-acting anti-HJV antibody into IND-enabling studies
  
  
  
   

DISC-3405: Anti-TMPRRS6 Antibody (Hepcidin Induction)

• Establish Phase 2 proof-of-concept of DISC-3405 for PV and support potential development into later stage development
  • Topline data from ongoing Phase 2 study in PV expected in 2026
• Initiation of Phase 1b study in patients with SCD anticipated by year end
• Plans to explore the role of therapeutic iron restriction in other indications
  
  
  
   

Bitopertin, DISC-0974, and DISC-3405 are investigational agents and are not approved for use as therapies in any jurisdiction worldwide.
