Purpose: Darolutamide (DARO) is a structurally distinct and highly potent androgen receptor inhibitor that improved overall survival (OS) and metastasis-free survival vs placebo (PBO), with a low incidence of treatment-emergent adverse events (TEAEs) in patients (pts) with nonmetastatic castration-resistant prostate cancer (CRPC). We investigated whether DARO in combination with standard androgen-deprivation therapy (ADT) + docetaxel would increase OS in pts with metastatic hormone-sensitive prostate cancer (mHSPC).

Methods: This international, double-blind, phase 3 study (NCT02799602), randomized pts with mHSPC 1:1 to DARO 600 mg twice daily or PBO in addition to ADT + docetaxel. Randomization was stratified by extent of disease according to TNM (M1a vs M1b vs M1c) and alkaline phosphatase levels (< vs ≥ upper limit of normal). The primary endpoint was OS. Secondary endpoints included times to CRPC, pain progression, first symptomatic skeletal event (SSE), and initiation of subsequent systemic antineoplastic therapies, and safety.

Results: From Nov 2016 to June 2018, 1306 pts (median age 67 years) were randomized, 651 to DARO and 655 to PBO, in combination with ADT + docetaxel. At the primary data cutoff (Oct 25, 2021), DARO significantly decreased the risk of death by 32.5% vs PBO (HR 0.68, 95% CI 0.57–0.80; P<0.001). The significant improvement in OS was observed even though substantially more pts received subsequent life-prolonging systemic antineoplastic therapy in the PBO arm (75.6%) vs the DARO arm (56.8%). The significant OS benefit was consistent across prespecified subgroups. DARO significantly delayed time to CRPC vs PBO (HR 0.36, 95% CI 0.30–0.42; P<0.001). Time to pain progression was also significantly longer with DARO vs PBO (HR 0.79, 95% CI 0.66–0.95; P=0.01), as were times to first SSE and start of subsequent systemic antineoplastic therapy. TEAEs were similar between study arms. In both arms, the incidences of the most common TEAEs (≥10%) were highest during the overlapping docetaxel treatment period, with grade 3/4 TEAEs of 66.1% for DARO and 63.5% for PBO, mainly due to neutropenia (33.7% vs 34.2%, respectively). TEAEs led to discontinuation of DARO and PBO in 13.5% and 10.6% of pts, respectively.

Conclusions: In pts with mHSPC, early treatment combining DARO with ADT + docetaxel significantly increased OS and improved key secondary endpoints vs ADT + docetaxel alone. The incidence of TEAEs was similar in the two treatment arms.
