Drug Farm's ALPK1 Inhibitor Shows Early Promise in ROSAH Syndrome Trial
Event summary
- Drug Farm presented positive interim Phase 1b results for DF-003, its first-in-class ALPK1 inhibitor, at APVRS 2026, showing improvements in visual function, anhidrosis, and systemic inflammation in ROSAH syndrome patients.
- The open-label study enrolled 11 adults with ROSAH syndrome across China, Australia, and the U.S., with 9 completing 78-day follow-up.
- Key findings included 11-letter improvements in visual acuity, reduced inflammatory biomarkers, and no serious adverse events during treatment.
- DF-003 demonstrated potent and selective inhibition of ALPK1, with preclinical data supporting its mechanism of action.
The big picture
Drug Farm's positive Phase 1b results for DF-003 mark a significant step in addressing ROSAH syndrome, a rare genetic autoinflammatory disease with no approved therapies. The company's AI-driven drug discovery platform and strategic focus on innate immunity position it at the forefront of precision medicine. The findings reinforce the potential of ALPK1 inhibition as a disease-modifying approach, with broader implications for other inflammatory conditions.
