Progression-free Survival (PFS) Per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) as Assessed by Investigator in Participants With Programmed Cell Death-Ligand 1 (PD-L1) Combined Positive Score (CPS) =1
Query!
Assessment method [1]
0
0
PFS was defined as the time from randomization to the first documented progressive disease (PD) or death due to any cause, whichever occurs first. Per RECIST 1.1, PD was defined as = 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of =5 mm. Note: The appearance of one or more new lesions was also considered PD. The PFS per RECIST 1.1 as assessed by Investigator for all randomized participants with PD-L1 CPS =1 is presented.

Number of Participants With a 10-point Change From Baseline in Quality of Life (QoL) Based on the European Organisation for the Research & Treatment of Cancer (EORTC) QoL Questionnaire-30 (QLQ-C30) Combined Global Score
Query!
Assessment method [9]
0
0
The EORTC QLQ-C30 is a questionnaire to assess the quality of life of cancer patients. Participant responses to "How would you rate your overall health during the past week?" (Item 29) and "How would you rate your overall quality of life during the past week?" (Item 30) are scored on a 7-point scale (1= Very poor to 7=Excellent). Raw scores are standardized with linear transformation so that scores range from 0-100. A higher combined score indicates a better overall health status. Participant post-baseline scores were classified based on change from baseline, "Improved": a =10-point improvement in score and confirmed by the next visit; "Stable": a =10-point increase or \<10-point change in score OR a \<10-point change in score and a =10-point increase in score at the next visit; or "Deteriorated": a =10-point deterioration in score when the criteria for improvement/stability weren't met. Participants who didn't meet "Improved", "Stable", or "Deteriorated" criteria reported as "Other".

Key inclusion criteria
* Has persistent, recurrent, or metastatic squamous cell carcinoma, adenosquamous carcinoma, or adenocarcinoma of the cervix which has not been treated with systemic chemotherapy and is not amenable to curative treatment (such as with surgery and/or radiation).

AEs due to previous treatments should be resolved to = Grade 1 or baseline. Participants with = Grade 2 neuropathy or = Grade 2 alopecia are eligible.
* Not pregnant or breastfeeding, and at least one of the following conditions applies: a.) Not a woman of childbearing potential (WOCBP), b.) A WOCBP must agree to use effective contraception during the treatment period and for at least 120 days after the last dose of pembrolizumab/placebo and 210 days after the last dose of chemotherapy/bevacizumab
* Has measurable disease per RECIST 1.1 as assessed by the local site investigator/radiology
* Has provided archival tumor tissue sample or newly obtained core or excisional biopsy of a tumor lesion not previously irradiated for prospective determination of Programmed Cell Death-Ligand 1 (PD-L1) status prior to randomization
* Has an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1 within 14 days prior to randomization
* Has adequate organ function

Key exclusion criteria
* A WOCBP who has a positive urine pregnancy test within 72 hours prior to randomization
* Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis. Participants with known brain metastases may participate provided that the brain metastases have been previously treated (except with chemotherapy) and are radiographically stable.

Replacement therapy (e.g. thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency) is not considered a form of systemic treatment and is allowed
* Has a history of (non-infectious) pneumonitis that required steroids or has current pneumonitis
* Has an active infection requiring systemic therapy
* Has a known history of human immunodeficiency virus (HIV) infection
* Has a known history of Hepatitis B or known active Hepatitis C virus infection
* Has a known history of active tuberculosis (TB; Bacillus tuberculosis)
* Has received prior therapy with an anti-PD-1, anti-PD-L1, or anti PD-L2 agent or with an agent directed to another stimulatory or co-inhibitory T-cell receptor (e.g. cytotoxic T-lymphocyte-associated protein 4 [CTLA-4], OX 40, CD137)
* Has received prior systemic chemotherapy for treatment of cervical cancer.
* Has not recovered adequately from toxicity and/or complications from major surgery prior to randomization
* Has received prior radiotherapy within 2 weeks prior to randomization. Participants must have recovered from all radiation-related toxicities, not require corticosteroids, and not have had radiation pneumonitis.
* Has received a live vaccine within 30 days prior to randomization
* Has severe hypersensitivity (=Grade 3) to pembrolizumab and/or any of its excipients.
* Has a contraindication or hypersensitivity to any component of cisplatin, carboplatin, paclitaxel, or bevacizumab
* Is currently participating in or has participated in a study of an investigational agent or has used an investigational device within 4 weeks prior to randomization
* Is pregnant or breastfeeding or expecting to conceive within the projected duration of the study, starting with the screening visit through 120 days following last dose of pembrolizumab/placebo and 210 days following last dose of chemotherapy/bevacizumab
* Has had an allogeneic tissue/solid organ transplant

Summary
Brief summary
The purpose of this study is to assess the efficacy and safety of pembrolizumab (MK-3475) plus one of four platinum-based chemotherapy regimens compared to the efficacy and safety of placebo plus one of four platinum-based chemotherapy regimens in the treatment of adult women with persistent, recurrent, or metastatic cervical cancer. Possible chemotherapy regimens include: paclitaxel plus cisplatin with or without bevacizumab and paclitaxel plus carboplatin with or without bevacizumab. The primary study hypotheses are that the combination of pembrolizumab plus chemotherapy is superior to placebo plus chemotherapy with respect to: 1) Progression-free Survival (PFS) per Response Evaluation Criteria in Solid Tumors (RECIST 1.1) as assessed by the Investigator, or, 2) Overall Survival (OS).
