AstraZeneca, MSD announce positive results from phase III PROfound trial of Lynparza to treat metastatic castration-resistant prostate cancer
AstraZeneca and MSD Inc, announced further positive results from the phase III PROfound trial of Lynparza (olaparib) in men with metastatic castration-resistant prostate cancer (mCRPC) who have a homologous recombination repair gene mutation (HRRm) and have progressed on prior treatment with new hormonal agent (NHA) treatments (e.g. enzalutamide and abiraterone). Results from the trial showed a statistically significant and clinically meaningful improvement in the key secondary endpoint of overall survival (OS) with Lynparza versus enzalutamide or abiraterone in men with mCRPC selected for BRCA1/2 or ATM gene mutations, a subpopulation of HRR gene mutations. The phase III PROfound trial had met its primary endpoint in August 2019, showing significantly improved radiographic progression-free survival (rPFS) in men with mutations in BRCA1/2 or ATM genes, and had met a key secondary endpoint of rPFS in the overall HRRm population.
