The study will integrate the efficacy of combining the anti programmed death-ligand 1 (anti-PD-L1) agent atezolizumab with the current standard of care in Stage IVB , persistent or recurrent carcinoma of the cervix, namely cisplatin/paclitaxel/bevacizumab. It will be explored the combination of bevacizumab plus atezolizumab, with no patient selection based on PD-L1 expression, allowing an all-comer assessment of atezolizumab activity.
The study is a randomized open label phase III trial to investigate the impact of atezolizumab in combination with bevacizumab and cisplatin/paclitaxel chemotherapy on overall survival and will employ the intent to treat principle, and random assignment to one of the 2 arms will be balanced according to disease histology (squamous versus adenocarcinoma), prior platinum therapy as a radiation sensitizer (no prior cis-Radiotherapy (RT) versus prior cis-RT) and chemotherapy backbone (cisplatin versus carboplatin).
This trial will be run in an open label design due to the following considerations: the control arm is the standard of care for women diagnosed with metastatic, persistant or recurrent cervical cancer because of its impact on overall survival and the primary endpoint of the study is overall survival (OS), so blinding is not needed to ensure a robust assessment.
