The Food and Drug Administration has approved enzalutamide (Xtandi) for patients with metastatic castration-sensitive prostate cancer (mCSPC).
The drug was previously approved for patients with castration-resistant prostate cancer.
Approval was based on radiographic progression-free survival (rPFS) improvement in ARCHES, a trial of 1,150 patients with mCSPC randomized to receive either enzalutamide or placebo daily. All patients received a gonadotropin-releasing hormone analogue or had a prior bilateral orchiectomy.
Median rPFS was not reached in the enzalutamide, arm compared with 19.4 months (95% confidence interval, 16.6 to not reached) in the placebo arm (HR 0.39; 95% CI, 0.30-0.50; P less than .0001), the FDA said in a statement.
The most common adverse reactions in enzalutamide-treated patients in ARCHES were hot flush, asthenia/fatigue, hypertension, fractures, and musculoskeletal pain.
The recommended dose is 160 mg (four 40 mg capsules) administered orally once daily with or without food, the FDA said.
