Brief Summary:

The purpose of this study is to compare overall survival (OS) and progression free survival (PFS) per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) as assessed by blinded independent central review (BICR).

Hypothesis (H1): Concurrent chemoradiation therapy with pembrolizumab followed by pembrolizumab plus olaparib is superior to concurrent chemoradiation therapy alone with respect to PFS per RECIST 1.1 by BICR.

Hypothesis (H2): Concurrent chemoradiation therapy with pembrolizumab followed by pembrolizumab is superior to concurrent chemoradiation therapy alone with respect to PFS per RECIST 1.1 by BICR.

Hypothesis (H3): Concurrent chemoradiation therapy with pembrolizumab followed by pembrolizumab plus olaparib is superior to concurrent chemoradiation therapy alone with respect to OS.

Hypothesis (H4): Concurrent chemoradiation therapy with pembrolizumab followed by pembrolizumab is superior to concurrent chemoradiation therapy alone with respect to OS.

    The EORTC QLQ-C30 is a questionnaire to assess the overall quality of life of cancer patients. Participant responses to the question "How would you rate your overall health during the past week?" are scored on a 7-point scale (1= Very poor to 7=Excellent). Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. A higher score indicates a better overall health status.
