Brief Summary:
Due to the high expression of PD-L1 in endometrial cancers as well as in ovarian cancers which are molecularly similar to uterine serous cancers, using pembrolizumab should be beneficial in this patient population. Since the investigators are able to get a pre-treatment research- related endometrial biopsy as well as the surgical specimen post two cycles of pembrolizumab, the investigators will be able to evaluate the mechanism of action of this drug on the endometrial cancer tumor environment.

Arm Intervention/treatment
Experimental: Arm 1: MK-3475
  • Patients will undergo endometrial biopsy followed by 2 doses of MK-3475 3 weeks apart. 3-4 weeks after the second dose of MK-3475, the standard of care surgical resection will take place, followed by standard of care adjuvant therapy. Tissue and blood will be collected at the time of surgical resection for immune analysis. For patients whose pathology confirms high-risk features and advanced stage, MK-3475 will be given every 3 weeks starting 4 -6 weeks after completion of adjuvant therapy for a maximum of 4 doses post-surgery.
  • MK-3475 will be given intravenously at a dose of 200 mg over the course of 30 minutes.
  • The standard of care chemotherapy will consist of 6 cycles of paclitaxel and carboplatin AUC 5 every 3 weeks for 6 cycles.
  • The decision to administer radiation therapy will be per the treating physician. If the patient does not receive radiation therapy, then the patient will start MK-3475 every 3 weeks x 4 doses after the completion of chemotherapy.
Drug: MK-3475
Other Names:
  • pembrolizumab
  • Keytruda

Procedure: Surgical resection (standard of care)
Drug: Paclitaxel (standard of care)
Other Name: Taxol

Drug: Carboplatin (standard of care)
Other Names:
  • Paraplat
  • Paraplatin

Radiation: Radiation (standard of care)
Procedure: Endometrial biopsy
Procedure: Peripheral blood draw



Primary Outcome Measures :
  1. Safety as measured by treatment related adverse events [ Time Frame: 90 days following last dose of MK-3475 (approximately 56 weeks) ]
    -The descriptions and grading scales found in the revised NCI Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 will be utilized for all adverse event reporting


Secondary Outcome Measures :
  1. Progression-free survival (PFS) [ Time Frame: Up to 2 years following completion of therapy ]
    • PFS is defined as the duration of time from start of treatment to time of progression or death, whichever occurs first.
    • Progressive Disease (PD): At least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or more new lesions is also considered progressions).

Criteria

Inclusion Criteria:

  • Diagnosis of FIGO grade 3 endometrioid cancer, serous, clear cell, or mixed high grade endometrial cancer with confirmation on research-related endometrial biopsy.
  • Radiographically confirmed endometrial adenocarcinoma of stages III-IV requiring adjuvant therapy. If stage III disease is suspected, there should be multiple pelvic and/or lymph nodes involved.
  • Measurable disease defined as lesions that can be accurately measured in at least one dimension (longest diameter to be recorded) as >10 mm with CT scan, as >20 mm by chest x-ray, or >10 mm with calipers by clinical exam by RECIST 1.1.
  • Treatment plan must include primary site biopsy followed by resection of the primary tumor site and any metastatic sites at time of surgery.
  • At least 18 years of age.
  • GOG performance status ≤ 2
  • Normal bone marrow and organ function as defined below:

    • Absolute neutrophil count ≥ 1,500/mcl
    • Platelets ≥ 100,000/mcl
    • Hemoglobin ≥ 9 g/dL
    • Total bilirubin ≤ 1.5 x IULN OR direct bilirubin ≤ IULN for patients with total bilirubin > 1.5 x IULN
    • AST(SGOT)/ALT(SGPT) ≤ 2.5 x IULN (or ≤ 5 x IULN for patients with liver metastases)
    • Serum creatinine ≤ 1.5 x IULN OR creatinine clearance by Cockcroft-Gault ≥ 60 mL/min/1.73 m2 for patients with creatinine levels > 1.5 x IULN
    • INR or PT ≤ 1.5 x IULN unless patient is receiving anticoagulant therapy as long as INR or PTT is within therapeutic range of intended use of anticoagulants
    • aPTT ≤ 1.5 x IULN unless patient is receiving anticoagulant therapy as long as INR or PTT is within therapeutic range of intended use of anticoagulants
  • Sexually active women of childbearing potential must agree to contraceptive methods as described by the protocol prior to study entry, for the duration of pre-operative study participation and until definitive hysterectomy/bilateral salpingo-oophorectomy. Should a woman become pregnant or suspect she is pregnant while participating in this study, she must inform her treating physician immediately.
