- Preliminary Efficacy Observed: In lower-risk MDS patients receiving doses of ≥500 mg QD, 33% of transfusion-dependent patients achieved red blood cell transfusion independence (RBC-TI), indicating R289's potential as a new treatment option in this challenging area.
- Patient Demographics: The median age of participants was 75, with 76% having previously received treatments like luspatercept, highlighting the drug's applicability in a difficult-to-treat population and its potential to improve patient quality of life.
- Good Tolerability: R289 was generally well tolerated across all dose groups, with a median treatment duration of 5.5 months, suggesting its safety in heavily pre-treated patients and providing confidence for future clinical trials.
- Future Research Outlook: Rigel anticipates selecting the recommended Phase 2 dose in the second half of 2026, aiming to further validate R289's efficacy and potentially offer new hope for lower-risk MDS patients.
