Mabwell Bioscience Hits Phase II Milestone with First‑Patient Dose of 9MW3011, the Only Anti‑TMPRSS6 Monoclonal Antibody for Polycythemia Vera

Shanghai‑listed Mabwell Bioscience (SHA: 688062) announced today that its anti‑TMPRSS6 monoclonal antibody 9MW3011 (R&D code 9MW3011/DISC‑3405) has entered the first‑patient, first‑dose cohort of a global Phase II trial. The drug, previously licensed to DISC Medicine, is poised to become the only therapeutic that targets the protease TMPRSS6 in polycythemia vera (PV), a rare myeloproliferative neoplasm.

Why 9MW3011 Matters

FeatureDetail
Mechanism9MW3011 blocks TMPRSS6, a key negative regulator of the iron‑homeostasis hormone hepcidin, thereby up‑regulating endogenous hepcidin and restoring physiological iron balance.
Clinical StatusPhase II – first‑patient dose on 24 Sept 2025
Phase Ib – three ongoing studies in China
FDA Designations – Fast‑Track & Orphan Drug
Competitive EdgeUnlike exogenous hepcidin mimetics, 9MW3011 offers a biologically relevant, endogenous‑hepcidin‑driven iron‑regulatory effect that could translate into fewer off‑target effects and better tolerability.
Target PopulationPatients with polycythemia vera, a disease lacking disease‑modifying therapies and associated with chronic iron overload and thrombosis risk.

Regulatory & Market Context

  • Fast‑Track & Orphan Drug Status – Accelerated review pathways from the U.S. FDA underscore the unmet need for PV therapies and the potential for a rapid market entrance.
  • Shanghai Market – With three Phase Ib trials already active in China, Mabwell is positioned to secure early commercial traction in a 1.4‑billion‑person market that is increasingly receptive to precision oncology and rare‑disease solutions.
  • Global Growth – The worldwide PV market is projected to exceed $1.2 billion by 2030, driven by rising prevalence and the search for disease‑modifying agents.

Forward‑Looking Statements

Mabwell cautions that the Phase II results will inform dose‑selection and safety evaluation for a planned Phase III study, and that regulatory milestones are subject to change based on emerging data.-Fineline Info & Tech
