RAD51B inact mut | prostate cancer | sensitive | Olaparib | FDA approved - On Companion Diagnostic | Actionable | In a Phase III trial (PROfound) that supported FDA approval, Lynparza (olaparib) treatment significantly improved median imaging-based progression-free survival (5.8 vs 3.5 mo, HR 0.49, p<0.001) compared to control in patients with metastatic castration-resistant prostate cancer who progressed on hormone therapy and harbored deleterious or suspected deleterious mutations in homologous recombination repair genes, including RAD51B (PMID: 32343890; NCT02987543). | detail... detail... 32343890 |
RAD51B inact mut | prostate cancer | sensitive | Olaparib | Guideline | Actionable | Lynparza (olaparib) is included in guidelines as second-line therapy post androgen receptor-directed therapy for patients with metastatic castration-resistant prostate cancer harboring pathogenic mutations in RAD51B (NCCN.org). | detail... |
RAD51B mutant | ovary serous adenocarcinoma | predicted - sensitive | Cediranib + Olaparib | Clinical Study - Cohort | Actionable | In a Phase II trial, Cediranib (AZD-2171) and Lynparza (olaparib) treatment was well tolerated, and resulted in an objective response (OR) of 9% (all partial), a 16-week progression-free survival (PFS) of 47%, and a disease control rate (DCR) of 68% in heavily pretreated high-grade serous ovarian cancer patients (n=34), and a median PFS of 4.8 months in patients (n=14) harboring mutations in either BRCA1, BRCA2, or RAD51B (PMID: 32444417; NCT02681237). | 32444417 |
