Nuvation Bio Expands Safusidenib Trials After Strong Phase 2 Data
Event summary
- Nuvation Bio reported updated Phase 2 data for safusidenib showing a 51.9% ORR and 79.1% 36-month PFS in IDH1-mutant glioma patients.
- The company will launch two new studies: a Phase 3 trial (G307) outside the U.S. and a Phase 2 trial (G209) for post-vorasidenib patients.
- Safusidenib demonstrated durable responses with no new safety signals after nearly 40 months of follow-up.
The big picture
Nuvation Bio is aggressively expanding its clinical program for safusidenib, targeting a broader spectrum of IDH1-mutant glioma patients. The move comes as targeted therapies gain traction in neuro-oncology, with safusidenib potentially addressing critical gaps in treatment sequencing. The company's strategy hinges on differentiating its drug in a competitive landscape where vorasidenib is already established.
