Brief Summary:
This phase III trial studies how well the combination of pembrolizumab, paclitaxel and carboplatin works compared with paclitaxel and carboplatin alone in treating patients with endometrial cancer that is stage III or IV, or has come back after a period of improvement (recurrent). Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Paclitaxel and carboplatin are chemotherapy drugs used as part of the usual treatment approach for this type of cancer. This study aims to assess if adding immunotherapy to these drugs is better or worse than the usual approach for treatment of this cancer.

Active Comparator: Arm I (placebo, paclitaxel, carboplatin)
COMBINATION PHASE: Patients receive placebo IV over 30 minutes on day 1 of each cycle, paclitaxel IV over 3 hours on day 1 of each cycle, and carboplatin IV over 30-60 minutes on day 1 of each cycle. Treatment repeats every 3 weeks for 6 cycles in the absence of disease progression or unacceptable toxicity. Patients with SD or PR who still have measurable disease may continue treatment for up to a total of 10 cycles (if deemed necessary by the treating physician) in the absence of disease progression or unacceptable toxicity. MAINTENANCE PHASE: Patients receive placebo IV over 30 minutes on day 1 of each cycle. Treatment repeats every 6 weeks for up to 14 cycles in the absence of disease progression or unacceptable toxicity. Patients undergo CT scan throughout the study.

Primary Outcome Measures :
- Progression-free survival (PFS) [ Time Frame: Duration of time from study entry to time of progression or death, whichever occurs first, or date of last contact if neither progression nor death has occurred, assessed up to 5 years ]Will be tested with a stratified log-rank statistic.
Secondary Outcome Measures :
- Incidence of adverse events [ Time Frame: 5 years ]Assessed by Common Terminology Criteria for Adverse Events (CTCAE). Toxicities will be screened for differences between treatments by using an exact method or a Chi-Square test. For a given adverse event, each patient will be graded according to the worse grade experienced while on therapy (and within 30 days of treatment). These toxicities will then be divided into two or three categories such as mild, moderate, and severe or mild to moderate versus severe. The rates of severe toxicities may be characterized by risk ratios or odds ratios with confidence intervals (unadjusted for multiplicity). The number of toxicities examined is usually fairly large, so these analyses will be considered exploratory and may be inspected in light of other studies.
- Objective tumor response [ Time Frame: 5 years ]Assessed by Response Evaluation Criteria for Solid Tumors (RECIST) 1.1.
- Duration of objective response [ Time Frame: 5 years ]The time difference between the dates of first response and first progression; patients who do not progress are considered censored.
- Overall survival (OS) [ Time Frame: Time from study entry to time of death or the date of last contact, assessed up to 5 years ]
- Quality of life (QoL) and patient-reported outcomes (PROs) [ Time Frame: 5 years ]Measured by the Function Assessment of Cancer Therapy (FACT)-Endometrial Trial Outcome Index (En-TOI), the FACT/Gynecologic Oncology Group (GOG)-Neurotoxicity (Ntx) subscale (short), Patient Reported Outcomes Measurement Information System (PROMIS)-Fatigue (short form),the PROMIS-physical function (short form) and a single-item measuring bother from side effects of cancer therapy. A linear mixed model for repeated measures will be used to estimate and compare the mean differences between the treatment groups. Model covariates will include the patients' randomly assigned study treatment, age at enrollment onto the study, pre-treatment quality of life/patient reported outcome score, assessment time and treatment-by-time interaction. The stratification factors will be the same factors included in the clinical primary analysis. Hochberg's step-up multiple testing procedure (Hochberg, 1988) will be used to adjust p-values for each assessment time points estimated from the fitted model.
- Incidence of pembrolizumab treatment and self-reported neurotoxicity [ Time Frame: 5 years ]Assessed with FACT/GOG-Ntx.
- Concordance between Institutional Mismatch repair (MMR) immunohistochemistry (IHC) testing and centralized MMR IHC [ Time Frame: 5 years ]Concordance between institutional MMR IHC testing and centralized MMR IHC. The patient's MMR IHC status will be assessed for prognostic value by conducting stratified log-rank tests or Cox Proportional Hazards (PH) modeling when assessing the impact on PFS or OS. When assessing the impact on the probability of response, a logistic regression model will be considered and include other pertinent variables that may influence response. A Cox PH model will be used to assess predictive value of MMR IHC status for regimen efficacy through an interaction term. A similar type of analysis may be attempted with response using logistic regression. The concordance of institutional MMR IHC testing and centralized MMR IHC will be characterized by agreement statistics such as kappa statistics (e.g. Cohen's kappa coefficient).
- Effect of pembrolizumab on PFS and OS by Program Death Ligand 1 (PD-L1) IHC [ Time Frame: 5 years ]Will assess the effect of pembrolizumab on PFS and OS by PD-L1 (combined positive score [CPS]) within proficient MMR (pMMR) and deficient MMR (dMMR) populations. The effectiveness of pembrolizumab will be compared by PD-L1 status (CPS). A formal test will be conducted by examining the interaction term between pembrolizumab treatment (yes or no) with PD-L1 status. The association between PD-L1 CPS status and MMR IHC status will be assessed with odds ratios. A test may be conducted with a Fisher's Exact Test, and confidence intervals will be provided.
- Association between PD-L1 IHC and MMR status [ Time Frame: 5 years ]Measures of association between PD-L1 IHC (CPS) and MMR IHC status. The concordance of institutional MMR IHC testing and centralized MMR IHC will be characterized by agreement statistics such as kappa statistics (e.g. Cohen's kappa coefficient).
