Ph 2 Study of Masofaniten + Enzalutamide in mCRPC Patients terminated; efficacy signals observed will not achieve target product profile

“Providing a meaningful clinical benefit to patients in our clinical trials, along with a robust safety profile, is of utmost importance to us at ESSA,” said David Parkinson, MD, President and CEO of ESSA Pharma Inc. “We designed this randomized study to rigorously evaluate the clinical benefit of adding masofaniten to enzalutamide. We made the difficult decision to terminate this Phase 2 study following the interim analysis because we concluded that the emerging efficacy profile of masofaniten combined with enzalutamide would not likely meet the primary endpoint of the study, nor our internal requirements for a prostate cancer therapy candidate. We would like to thank our partners, investigators, employees, and most importantly, the patients and their families involved in our clinical trials.”
