RAD51B wild-type | breast cancer | not applicable | N/A | Preclinical | Emerging | SiRNA inhibition of RAD51B in breast cancer cells resulted in increased sensitivity to DNA damaging agents in culture, suggesting that RAD51B could be a promising therapeutic target for sensitization to chemotherapeutic agents in combination therapies (PMID: 25368520). | 25368520 |
RAD51B wild-type | 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 rate (ORR) of 9% (all partial), a 16-week progression-free survival (PFS) of 47%, and a disease control rate (DCR) of 68% in high-grade serous ovarian cancer patients (n=34), and a median PFS of 6.4 months and 1.9 months in patients harboring wild-type (n=9) and reversion mutations (n=5) in either BRCA1, BRCA2, or RAD51B, respectively (PMID: 32444417; NCT02681237). | 32444417 |
