Betta Pharmaceuticals (SHE: 300558) announced that the National Medical Products Administration (NMPA) has approved the initiation of a clinical study for BPI-572270, a novel pan‑RAS “non‑degrading molecular glue” inhibitor, in patients with advanced solid tumors.
Regulatory Milestone & Drug Profile
| Item | Detail |
|---|---|
| Company | Betta Pharmaceuticals (SHE: 300558) |
| Drug | BPI-572270 |
| Mechanism | Pan‑RAS non‑degrading molecular glue inhibitor |
| Indication | Advanced solid tumors |
| Approval | NMPA clinical trial authorization |
| Innovation | First‑in‑class CYPA‑mediated RAS mutant binding approach |
| Development Stage | Phase I ready |
Mechanism of Action & Differentiation
- Molecular Glue Technology: BPI-572270 induces Cyclophilin A (CYPA), a widely expressed chaperone protein, to bind to activated RAS mutant proteins in tumor cells
- Signal Blockade: This binding triggers a conformational change in RAS, preventing interaction with downstream effectors such as cRAF
- Pathway Inhibition: Consequently blocks the MAPK signaling cascade that drives tumor proliferation and survival
- Competitive Edge: Represents a non‑degrading approach that sequesters rather than destroys RAS, potentially offering a more durable and safer therapeutic window compared to covalent RAS inhibitors
Market Impact & Commercial Outlook
- RAS Mutation Prevalence: ~30% of all solid tumors harbor RAS mutations, including 90% of pancreatic, 50% of colorectal, and 30% of lung cancers
- Unmet Need: No approved pan‑RAS inhibitors currently exist; represents one of oncology’s highest‑value opportunities
- Market Potential: Global RAS‑targeted therapy market projected to exceed $10 billion :by 2030 if clinically validated
- Competitive Landscape: Betta joins Revolution Medicines, Mirati (Amgen), and BridgeBio in RAS race; BPI-572270’s独特CYPA mechanism offers differentiation
- Strategic Value: NMPA approval positions Betta as a leader in China’s innovative oncology pipeline; may attract global partnership interest
- Next Steps: Phase I trial initiation targeted for Q2 2026; initial safety and efficacy data expected H2 2027
