Scientific Rationale

  • Target: Interleukin‑11 (IL‑11) / IL‑11Rα signaling, a key driver of fibroblast activation and extracellular‑matrix deposition in fibrotic diseases.
  • Mechanism: 9MW3811 binds IL‑11 with picomolar affinity, blocking downstream STAT3‑mediated transcription that fuels scar formation.
  • Pre‑clinical Evidence:
  • Pulmonary fibrosis models: Significant reduction in collagen deposition and lung stiffness.
  • Human‑derived keloid xenograft models: ↓ scar volume > 45 % and marked histologic reversal of fibrosis.
  • Uterine bleeding models: Attenuated endometrial fibrosis, suggesting broader gynecologic utility.

Market & Competitive Landscape

  • Unmet Need: Pathological scarring affects ≈ 30 million patients worldwide, with limited therapeutic options beyond surgery and corticosteroids.
  • Potential Revenue: Global scar‑treatment market projected to exceed $5 billion by 2030; a disease‑modifying biologic could capture a double‑digit share.
  • Competitive Edge: 9MW3811 is the only IL‑11‑targeted agent in clinical development, positioning Mabwell as a first‑mover in a novel fibrosis pathway.

Financial & Investor Implications

  • R&D Funding: Mabwell earmarks RMB 300 million (≈ US$42 million) for the Phase 2 program, funded largely from existing cash reserves and a recent private placement.
  • Share Reaction: Shanghai‑listed shares rose ≈ 4.1 % in early trading, reflecting investor confidence in the differentiated mechanism.
  • Future Outlook: Successful Phase 2 read‑out could unlock global Phase 3 partnerships and accelerate licensing discussions with multinational pharma seeking anti‑fibrotic pipelines.
