RedHill Announces Initiation of Phase 2 Study of Opaganib and Darolutamide in Advanced Prostate Cancer

The 80-patient placebo-controlled randomized Phase 2 study will evaluate the efficacy of opaganib in combination with Bayer’s darolutamide in men with metastatic castrate-resistant prostate cancer (mCRPC), testing the potentially enhancing effect of opaganib in patients with a poor prognosis

The study is being financially supported by Bayer (ETR: BAYN) and the Ramsay Hospital Research Foundation, and will be led by Professor Lisa Horvath from Chris O’Brien Lifehouse and the Australian and New Zealand Urogenital and Prostate Cancer Trials Group (ANZUP)

The study will utilize a companion lipid biomarker test (PCPro[1]) to select mCRPC patients who have a poor prognosis due to standard of care treatment and who may benefit from an opaganib + darolutamide combination treatment approach. Primary endpoint will be improved 12-month radiographic progression-free survival (rPFS)

Prostate cancer (PC) is the second most diagnosed cancer in the world, with around 1.5 million new cases per year, causing almost 400,000 deaths. People with mCRPC have few treatment options available to them. The prostate cancer market is valued at approximately $12 billion[2]

With multiple U.S. government collaborations for chemical and medical countermeasures and pandemic preparedness, opaganib is a novel, host-directed, potentially broad acting, orally administered small molecule, clinical-stage drug with demonstrated safety & efficacy profiles, being developed for various oncology, viral infections, inflammatory diseases and chemical and nuclear/radioprotection indications
