Brief Summary:
This phase III trial compares whether the addition of pembrolizumab to radiation therapy is more effective than radiation therapy alone in reducing the risk of cancer coming back (recurrence) in patients with newly diagnosed stage I-II endometrial cancer. 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. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. The addition of pembrolizumab to radiation treatment may be more effective than radiation treatment alone in reducing cancer recurrence.

Detailed Description:

PRIMARY OBJECTIVE:

I. To compare the 3-year recurrence-free survival of women with high intermediate risk (HIR) stage I/II mismatch repair deficient (dMMR) endometrioid endometrial cancer treated with radiation and pembrolizumab (MK-3475) versus radiation alone.

SECONDARY OBJECTIVES:

I. To describe the safety and tolerability of concurrent pembrolizumab (MK-3475) and radiation compared to radiation alone in patients with MMR deficient high intermediate risk endometrial cancer (HIR EC).

II. To describe the recurrence patterns in each group. III. To measure recurrence free survival at 5 years in each group. IV. To estimate disease specific overall survival in each group. V. To determine whether the addition of pembrolizumab (MK-3475) to radiation, compared with radiation alone is associated with decreased quality of life at 6- and 24-weeks, as measured with the Functional Assessment of Cancer Therapy (FACT)-Endometrial (En) Trial Outcome Index (TOI), increased gastrointestinal (GI) symptoms as measured with the GI subscale, and increased fatigue as measured with the Patient Reported Outcomes Measurement Information System (PROMIS)-Fatigue scale (short form).

VI. To validate the Functional Assessment of Cancer Therapy-Immune Checkpoint Modulator (FACT-ICM) subscale, which assesses in cancer patients on immunotherapy.

EXPLORATORY OBJECTIVES:

I. To explore the baseline tumor genetic and microenvironment parameters predictive of clinical benefit or resistance to immunotherapy.

II. To determine whether the addition of pembrolizumab (MK-3475) to radiation, compared with radiation alone, is associated with decreased quality of life as measured with the Functional Assessment of Cancer Therapy-Immune Checkpoint Modulator (FACT-ICM subscale) and more self-reported bother from side effects as measured with a single item GP5 "I am bothered by side effects," a question from the FACT-En TOI.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I: Patients undergo pelvic external beam radiation therapy (EBRT) daily for 5-6 weeks and vaginal brachytherapy completed within 7 days after completion of EBRT in the absence of disease progression or unacceptable toxicity.

ARM II: Patients undergo EBRT and brachytherapy as in Arm I. Within 7 days prior to the start of radiation therapy, patients also receive pembrolizumab intravenously (IV) over 30 minutes on day 1. Treatment with pembrolizumab repeats every 6 weeks for up to 1 year (9 cycles) in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months for 2 years and then every 6 months for 3 years.

Primary Outcome Measures :
  1. 3 year recurrence-free survival [ Time Frame: Time from study entry (randomization) to the time of cancer recurrence, assessed at 3 years ]
    Will be estimated using the Kaplan Meier method and treatment comparisons will be made using a stratified log-rank test.


Secondary Outcome Measures :
  1. Incidence of adverse events [ Time Frame: 12 months ]
    Will be assessed by Common Terminology Criteria for Adverse Events (CTCAE) by treatment regimen. Will be evaluated descriptively using frequencies and percentages and will be reported using tables. Differences between treatment arms will be assessed through absolute deviations and contingency table analyses. All patients who receive treatment, will be evaluated for toxicity. Toxicities by type and maximum grade over the course of treatment and follow up will be summarized and by date of occurrence (acute toxicity and late adverse effects).

  2. Recurrence patterns [ Time Frame: 5 years ]
    The cumulative incidences of vaginal recurrence, pelvic recurrence, retroperitoneal, and distant recurrence from endometrial cancer will be estimated within treatment regimen. Treatments will be compared graphically using Kaplan-Meier estimates of the survival function.

  3. 5 year recurrence free survival [ Time Frame: Time from study entry (randomization) to the time of cancer recurrence, assessed at 5 years ]
    Proportions will be compared by treatment using Fisher's exact test. This analysis may be delayed until the data are mature.

  4. Overall survival [ Time Frame: Duration of time from study entry to time of death or the date of last contact, assessed up to 5 years ]
    Will be estimated using the Kaplan Meier method and treatment comparisons will be made using a stratified log-rank test.

  5. Patients reported outcomes [ Time Frame: Up to 2 years after starting treatment ]
    Will be assessed by questionnaire.


Other Outcome Measures:
  1. Potential transformations of the severity of adverse events [ Time Frame: 12 months ]
    An example of potential transformation of the severity of adverse events is whether or not the patient experienced >= grade 3 events. It will be assessed by CTCAE and treatment regimen.

  2. Biomarker analysis [ Time Frame: Baseline ]
    Will assess baseline genetic characteristics (e.g. mutations) and microenvironment parameters, treatment, and interactions between treatment and biomarkers in a Cox regression.

  3. Functional Assessment of Cancer Therapy (FACT)-Immune Checkpoint Modulator (ICM) subscale [ Time Frame: Up to 2 years after starting treatment ]
    Treatment differences in the FACT-ICM subscale and self-reported bother from side effects will be explored using a linear mixed model for repeated measures, adjusted for the baseline score.
