The Inhibition of Polymerase in Tumors from BRCA Mutation Carriers
Background • Inhibiting polyADP polymerase is key in the treatment of cancers that have DNA-repair defects
Methods • A phase 1 trial of the pharmacokinetic and pharmacodynamics traits of olaparib was done and aimed at studying carriers of BRCA1 and BRCA2.
Results • 60 patients were treated; 20 of them were carriers of either BRCA1 or BRCA2 mutations. Objective antitumor activity was reported in mutation carriers, all of which had ovarian, breast, or prostate cancer and got several treatment regimens.
Conclusion • Olaparib has antitumor activity associated with BRCA1 and BRCA2 mutations.
