Epithelial Ovarian Cancer Clinical Trial
Official title:
A Phase IIIb, Randomised, Double-blind, Placebo-controlled, Multicentre Study of Olaparib Maintenance Retreatment in Patients With Epithelial Ovarian Cancer Previously Treated With a PARPi and Responding to Repeat Platinum Chemotherapy
The OReO study will be a Phase IIIb, randomised, double-blind, placebo-controlled, multicentre study to assess the efficacy and tolerability of Olaparib retreatment, versus matching placebo, in non-mucinous epithelial ovarian cancer (EOC) patients (including patients with primary peritoneal and/or fallopian tube cancer)
The OReO study will investigate the efficacy and safety of Olaparib maintenance re-treatment in patients with relapsed non-mucinous EOC, who have had disease progression following maintenance therapy with a Polyadenosine 5'diphosphoribose [poly (ADP ribose)] polymerisation inhibitor (PARPi) and a complete or partial radiological response to subsequent treatment with platinum-based chemotherapy or may have no evidence of disease (if optimal cytoreductive surgery was conducted prior to chemotherapy), and no evidence of a rising CA-125. Patients will be enrolled on the basis of their breast cancer susceptibility gene (BRCA1, BRCA2) status into one of two cohorts (BRCA1/2 [+ve] and BRCA1/2 [-ve]). The BRCA1/2 (+ve) and BRCA1/2 (-ve) cohorts will be randomised separately. Within each cohort, patients will be randomised by prospective allocation in a 2:1 ratio (Olaparib: matching placebo). ;
