Astellas Pharma sNDA Approved for Xospata
FDA has approved an Astellas Pharma supplemental NDA to update the U.S. product labeling for Xospata (gilteritinib) to include final analysis data from the ADMIRAL trial. The data demonstrated improvement in overall survival in patients treated with gilteritinib monotherapy versus salvage chemotherapy in adult patients with relapsed or refractory acute myeloid leukemia (AML) with an FMS-like tyrosine kinase 3 (FLT3) mutation, according to the company. Results from the trial showed that the median overall survival for patients who received Xospata was 9.3 months compared to 5.6 months for patients who received salvage chemotherapy.
Xospata’s safety profile is based on 319 patients with relapsed or refractory AML in three clinical trials (NCT02421939, NCT02014558, and NCT02181660). Fatal adverse reactions occurred in 2% of patients receiving Xospata, which included cardiac arrest (1%) and one case each of differentiation syndrome and pancreatitis, Astellas says. The most frequent nonhematological serious adverse reactions reported in patients were fever (13%), dyspnea (9%), renal impairment (8%), transaminase increased (6%) and noninfectious diarrhea (5%), it adds.
