    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".

Brief Title  ICMJE Efficacy and Safety Study of First-line Treatment With Pembrolizumab (MK-3475) Plus Chemotherapy Versus Placebo Plus Chemotherapy in Women With Persistent, Recurrent, or Metastatic Cervical Cancer (MK-3475-826/KEYNOTE-826)
Official Title  ICMJE A Phase 3 Randomized, Double-Blind, Placebo-Controlled Trial of Pembrolizumab (MK-3475) Plus Chemotherapy Versus Chemotherapy Plus Placebo for the First-Line Treatment of Persistent, Recurrent, or Metastatic Cervical Cancer (KEYNOTE-826)
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).
