In men with metastatic castration-resistant prostate cancer who had disease progression while receiving enzalutamide (Xtandi) or abiraterone (Zytiga) and who had alterations in genes with a role in homologous recombination repair, olaparib (Lynparza) was found to be associated with longer progression-free survival (PFS) and improved measures of response and patient-reported end points than either enzalutamide or abiraterone, according to results from the phase III PROfound trial published in The New England Journal of Medicine.
The randomized, open-label clinical trial also found that a benefit was observed in the overall trial population with an alteration in any of the prespecified genes with a direct or indirect role in homologous recombination repair.
