NSABP-B-55/BIG6-13; A Randomised Double-blind Parallel Group Placebo-controlled Multi-centre Phase III Study to Assess the Efficacy and Safety of Olaparib Versus Placebo as Adjuvant Treatment in Patients With Germline BRCA1/2 Mutations and High Risk HER2 Negative Primary Breast Cancer Who Have Completed Definitive Local Treatment and Neoadjuvant or Adjuvant Chemotherapy

Study Overview

The purpose of this study is to determine the effects of olaparib treatment in patients with germline BRCA1/2 mutations and high risk HER2 negative primary breast cancer who have completed definitive local treatment and neoadjuvant or adjuvant chemotherapy.

Study Description

Patients will be randomised in 1:1 ratio to either olaparib or placebo. Randomisation will be stratified by prior neoadjuvant versus adjuvant chemotherapy and prior platinum use for breast cancer. Randomised patients will receive study treatment for up to a maximum of 12 months. All patients will have safety assessments every 2 weeks during the first month, every 4 weeks for the following 5 months and 3 monthly for the remaining 6 months of study treatment plus 30 days after its discontinuation. Following randomisation, all patients will be assessed regularly for signs, symptoms and evidence of disease recurrence by taking medical history, physical examination and mammogram/breast MRI. Efficacy assessments will be performed on a 3 monthly basis during the first 2 years, followed by 6 monthly assessments for years 3, 4 and 5 and annually thereafter. All patients (except those with bilateral mastectomy) will have mammogram / breast MRI annually for 10 years beginning 6 months after randomisation. All randomised patients will have clinical assessment visits for 10 years following their randomisation into the study. Once a patient completes 10 years of clinical assessment they will enter the survival follow up phase of the trial which will continue until 10 years after the last patient is randomised.
