Fosun Pharma Launches Phase 2 Trial of FXS7553 DPP‑1 Inhibitor for COPD in China

Fosun Pharmaceutical (Group) Co., Ltd. (SHA: 600196, HKG: 2196) announced that FXS7553 has initiated a Phase 2 clinical trial in China for the treatment of chronic obstructive pulmonary disease (COPD). The compound is a small‑molecule oral DPP‑1 inhibitor independently developed by Fosun Pharma, and no drug with the same molecular mechanism has been approved for marketing in China to date.

Drug Profile & Mechanism of Action

  • Molecule: FXS7553, a small‑molecule oral DPP‑1 (dipeptidyl peptidase‑1) inhibitor independently developed by Fosun Pharma
  • Mechanism: Inhibits DPP‑1, an enzyme that activates pro‑inflammatory serine proteases in neutrophils, thereby aiming to reduce neutrophil‑driven airway inflammation and damage
  • Indication Scope: Intended for the treatment of non‑cystic fibrosis bronchiectasis, COPD, and other indications
  • Pipeline Progress: FXS7553 has already entered a Phase 2 trial for non‑cystic fibrosis bronchiectasis, with COPD now becoming the second indication in Phase 2 development

Market Impact & Outlook

  • First‑In‑Class Opportunity in China: With no DPP‑1 inhibitor approved for marketing domestically, FXS7553 is positioned in a mechanistically novel space for Chinese respiratory patients.
  • Large Disease Burden: COPD affects more than 100 million people in China and remains one of the leading causes of morbidity and mortality, yet treatment options that address underlying neutrophilic inflammation remain limited.
  • Multi‑Indication Strategy: Parallel Phase 2 programs in non‑cystic fibrosis bronchiectasis and COPD allow Fosun Pharma to de‑risk development across related neutrophil‑driven respiratory diseases from a single asset.
  • Portfolio Expansion: The Phase 2 initiation reinforces Fosun Pharmaceutical’s push to build a differentiated innovative drug pipeline in respiratory medicine alongside its established commercial platforms.
