Phase III Investigational Trial of NUBEQA® (darolutamide) in Combination with Docetaxel and Androgen Deprivation Therapy (ADT) Meets Primary Endpoint of Significantly Increasing Overall Survival (OS) in Patients with mHSPC

  • Phase III ARASENS trial meets primary endpoint of overall survival for NUBEQA in combination with docetaxel and androgen deprivation therapy (ADT) versus docetaxel and ADT, a standard of care in men with metastatic hormone-sensitive prostate cancer (mHSPC)
  • Bayer plans to present these pivotal data at a forthcoming scientific congress and discuss them with health authorities
  • ARASENS is part of broad development program for NUBEQA, which includes another ongoing Phase III trial in mHSPC, ARANOTE, evaluating NUBEQA plus ADT

San Francisco, CA (UroToday.com) -- The Phase III ARASENS trial investigating the use of the oral androgen receptor inhibitor (ARi) NUBEQA® (darolutamide) in metastatic hormone-sensitive prostate cancer (mHSPC) has met its primary endpoint. In the ARASENS trial, NUBEQA in combination with docetaxel and androgen deprivation therapy (ADT) significantly increased overall survival (OS) compared to docetaxel and ADT. The overall incidence of reported adverse events was similar between treatment arms. Detailed results of the study are planned to be presented at an upcoming scientific congress. NUBEQA is currently indicated for the treatment of patients with non-metastatic castration-resistant prostate cancer (nmCRPC).


The ARASENS trial investigating NUBEQA is the only Phase III randomized, multi-center, double-blind trial, which was prospectively designed to evaluate the efficacy and safety of a combination of an ARi with docetaxel and ADT compared to docetaxel and ADT in patients with mHSPC.1

“For patients with mHSPC, there remains a significant need for new therapeutic approaches that improve treatment outcomes. ARASENS was prospectively designed to investigate whether combining NUBEQA with docetaxel and ADT could lead to an increase in overall survival for men with mHSPC,” said Scott Z. Fields, M.D., Senior Vice President and Head of Oncology Development at Bayer's Pharmaceutical Division. “We are especially grateful to the patients and investigators for participating in this important trial and look forward to presenting the full results at an upcoming meeting.”
Bayer plans to discuss the data from ARASENS with health authorities worldwide regarding the submission of NUBEQA for marketing authorization in this indication.

About the ARASENS Trial1

The ARASENS trial (NCT02799602) is a randomized, Phase III, multi-center, double-blind, placebo-controlled trial, which was prospectively designed to investigate the safety and efficacy of oral NUBEQA, an androgen receptor inhibitor (ARi), in combination with the chemotherapy docetaxel and androgen deprivation therapy (ADT) in patients with metastatic hormone-sensitive prostate cancer (mHSPC). 1,306 newly diagnosed patients were randomized in a 1:1 ratio to receive 600 mg of NUBEQA twice a day or matching placebo, in addition to docetaxel and standard ADT.

The primary endpoint of this trial is overall survival (OS). Secondary endpoints include time to castration-resistant prostate cancer (CRPC), time to initiation of subsequent anticancer therapy, time to first symptomatic skeletal event (SSE), time to pain progression, all measured at 12‐week intervals, as well as adverse events as a measure of safety and tolerability.

About the ARANOTE Trial

The ARANOTE trial (NCT04736199) is a randomized, double-blind, placebo-controlled Phase III study of NUBEQA in addition to androgen deprivation therapy (ADT) versus placebo plus ADT in men with metastatic hormone-sensitive prostate cancer (mHSPC). The primary endpoint of this study is radiological progression-free survival (rPFS), as measured as the time from the date of randomization to the date of first documentation of radiological progressive disease or death due to any cause, whichever occurs first.
