Recent results and decisions
- Aug 13, 2026positive Post hoc analysis of Phase 3 MATTERHORN presented at EHA 2026 showed clinically meaningful improvement in transfusion independence versus placebo in HTB LR-MDS, with similar rates in RS+ and RS- disease.
In a post hoc analysis of the Phase 3 MATTERHORN study, patients treated with roxadustat showed a clinically meaningful improvement in transfusion independence (TI) in patients with LR-MDS and HTB compared to placebo.
Filing - Mar 16, 2026positive Investigator-sponsored FG-3246 plus enzalutamide study in mCRPC showed median rPFS of 7.0 months overall and 10.1 months in patients who progressed on only one prior ARPI (presented at ASCO GU 2026).
FG-3246 and enzalutamide combination therapy, in biomarker unselected patients with androgen receptor pathway inhibitor (ARPI)-treated, taxane-naïve mCRPC, led to a median radiographic progression free survival (rPFS) of 7.0 months in the overall study cohort, with median rPFS of 10.1 months observe
