Orion’s collaboration partner Bayer has announced the U.S. Food and Drug Administration (FDA) has accepted a supplemental New Drug Application (sNDA) and granted Priority Review for the oral androgen receptor inhibitor (ARi) darolutamide in combination with docetaxel for the treatment of metastatic hormone-sensitive prostate cancer (mHSPC).

The application is being conducted under the FDA Oncology Center of Excellence’s (OCE) Project Orbis initiative, which provides a framework for concurrent submission and review of cancer treatments among participating international health authorities.

The Phase III ARASENS trial

The sNDA is based on positive results from the Phase III ARASENS trial demonstrating a statistically significant improvement in overall survival (OS) for darolutamide plus androgen deprivation therapy (ADT) and docetaxel in men with mHSPC compared to ADT plus docetaxel, which were published in The New England Journal of Medicine. Darolutamide is already approved in more than 60 markets around the world, including the U.S., the European Union (EU), Japan and China, under the brand name Nubeqa, for the treatment of patients with non-metastatic castration-resistant prostate cancer (nmCRPC), who are at high risk of developing metastatic disease.

Darolutamide is developed jointly by Orion and Bayer. Bayer recently submitted applications for additional indication of darolutamide to the European Medicines Agency (EMA), the Ministry of Health, Labor and Welfare (MHLW) in Japan, and China’s Center of Drug Evaluation (CDE). Additional submissions in mHSPC are planned globally by Bayer.
