Time frame
Assessments every 8 weeks from C1D1 until disease progression, death, or initiation of subsequent treatment. After 18 months on study, assessments every 16 weeks. Total follow-up was up to approximately 3.5 years.

What was measured

A secondary endpoint is the ORR for the Treatment Part of the study. ORR is defined as the percentage of patients with a confirmed CR (complete response) or PR (partial response) by RECIST v1.1. The confirmed response is defined as a CR or PR on subsequent tumor assessment at least 28 days after first response documentation. CR is disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. PR is at least a 30% decrease in the sum of the longest diameter of target lesions, taking as reference the baseline sum of longest diameter.

Analysis population: Efficacy population with measurable disease at baseline. Efficacy population defined as all randomized patients with a deleterious BRCA mutation, excluding those identified to have a BRCA reversion mutation.
