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 ORR for the Treatment Part of the study defined as the percentage of patients with best response of CR or PR using RECIST v1.1 or response per Gynecologic Cancer InterGroup Cancer Antigen 125 (GCIG CA-125) criteria. Complete response (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. Partial response (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. Response to CA-125 has occurred if there is at least a 50% decrease from baseline: 1. in a sample collected after initiation of study treatment AND 2. that is confirmed in a subsequent sample collected ≥21 days after the prior sample. The absolute value of this confirmatory sample must be ≤110% of the prior sample. The date when the first sample with a 50% decrease from baseline is observed is the date of the CA-125 response.

Analysis population: Intent-to-treat (ITT) population with measurable disease at baseline and/or CA-125 response evaluable. ITT population defined as all randomized patients.
