A Study to Learn About the Investigational Drug Rinzimetostat (ORIC-944) in Patients With mCRPC Who Were Previously Treated With Abiraterone Acetate (Himalayas-1) (Himalayas-1)

2026년 9월 2일 업데이트: ORIC Pharmaceuticals

A Phase 3, Randomized, Open-Label Study of Rinzimetostat (ORIC-944) in Combination With Darolutamide Compared With ARPI or Docetaxel in Patients With Metastatic Castration Resistant Prostate Cancer Previously Treated With Abiraterone Acetate (Himalayas-1)

Himalayas-1 is a randomized, open-label, global, multicenter phase 3 study evaluating whether the combination of rinzimetostat with darolutamide is more effective compared to physician's choice of control; ARPI (darolutamide or enzalutamide) or docetaxel for treating patients with metastatic castration resistant prostate cancer (mCRPC) who were previously treated with abiraterone acetate.

The primary objective of this study is to demonstrate superiority in radiographic progression free survival (rPFS) of the investigational arm of rinzimetostat + darolutamide combination versus physician's choice of control: ARPI (darolutamide or enzalutamide) or docetaxel.

  • Known or suspected brain metastasis or active leptomeningeal disease
  • Clinically significant cardiovascular disease defined as:
