NCT03038100 · STUDY IN CONTEXT

A Study of Atezolizumab Versus Placebo in Combination With Paclitaxel, Carboplatin, and Bevacizumab in Participants With Newly-Diagnosed Stage III or Stage IV Ovarian, Fallopian Tu

Draft scope assessment: narrower. Linked by condition-string match at the cancer-entity level. The study's eligibility - stage, biomarker, treatment line and prior therapy - has not been reconciled against this page's definition, so its population is narrower than this page in ways not yet recorded. The condition was transformed or resolved through the terminology hierarchy to reach this cancer type, so the link itself is a candidate a reviewer must confirm. Found because this study's registry identifier is printed in an FDA approval notice, an FDA product label or an NCI summary held by this site. The citing document and the exact position of the identifier inside it are recorded. Being cited is not a statement that the study supports this treatment.

    Participants in the primary tumor-reductive surgery group received paclitaxel, carboplatin, atezolizumab placebo IV infusion on Day 1 of each 21-day cycle for a total of 6 cycles, and bevacizumab IV infusion starting with Cycle 2 for a total of 5 cycles, followed by maintenance therapy bevacizumab with atezolizumab placebo for a total of 22 cycles of atezolizumab placebo and 21 cycles of bevacizumab. Participants in the neoadjuvant therapy group received paclitaxel, carboplatin and placebo for 6 cycles and bevacizumab for 4 cycles. Interval surgery will occur between cycles 3 and 4. Each cycle is 21 days long. After 6 cycles, participants started maintenance therapy of bevacizumab and placebo for additional 16 cycles.
