Purpose

This is a single arm, Phase II study using the combination of atezolizumab and bevicacizumab in women with advanced, recurrent or persistent endometrial cancer. Safety and futility of this drug combination will be assessed to see what effect this treatment has on this patient population.

Detailed Description

      This phase 2 study using atezolizumab and bevacizumab aims to study the objective tumor
      response in women with recurrent endometrial cancer. Drugs will be administered via IV every
      21 days until disease progression, unacceptable toxicity, or loss of clinical benefit as
      determined by investigator. Subjects will receive routine cancer care as well as tests and
      procedures required for the purposes of this study. It is expected this combination will be
      produce an anti-cancer effect with manageable toxicities in this patient population.

Eligibility Criteria

        Inclusion Criteria:

          1. Histologic or cytologic diagnosis of endometrial carcinoma (including endometrioid,
             serous, mixed adenocarcinoma, clear-cell carcinoma, or carcinosarcoma).

          2. Evidence that the endometrial cancer is advanced, recurrent, or persistent and has
             relapsed or is refractory to curative therapy or established treatments.

          3. At least 1 prior platinum-based chemotherapeutic regimen, but not more than 2 prior

             may include chemotherapy, and/or consolidation/maintenance therapy.

          4. Measurable disease by RECIST 1.1, defined as at least 1 lesion that can be accurately
             measured in at least 1 dimension (longest diameter to be recorded). Each lesion must
             be ≥ 10 mm in long axis when measured by CT, MRI, or caliper measurement by clinical
             exam. Lymph nodes must be ≥ 15 mm in short axis when measured by CT or MRI.

          5. Female patients 18 years or older.

          6. Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2

          7. For women of childbearing potential: agreement to remain abstinent (refrain from
             heterosexual intercourse) or use contraceptive methods as defined in study protocol.

          8. Clinical laboratory values as specified in study protocol within 4 weeks before the
             first dose of study drug.

          9. Able to understand and willing to sign the Informed Consent Form and the written
             consent must be given before performance of any study-related procedure not part of
             standard medical care, with the understanding that consent may be withdrawn by the
             patient at any time without prejudice to future medical care.

         10. Must have ability to comply with the study protocol, in the investigator's judgment.

         11. Patients MSI status must be known (via immunohistochemistry)

         12. Patients should have archival tumor tissue available or agree to have pre-treatment
             tumor biopsy if no archival tissue is available for correlative studies If unable to
             be safely biopsied and patient desires enrollment, may be enrolled per principal
             investigator discretion.

         13. Life expectancy of greater than 12 weeks.

        Exclusion Criteria:

          1. Positive serum pregnancy test during the screening period or a positive urine
             pregnancy test on Day 1 before first dose of study drug. Women who are lactating and
             breast feeding are not eligible.

          2. Previous treatment with anti-PD-1, or anti-PD-L1 therapeutic antibody.

          3. History of auto-immune disorders (SLE, sarcoidosis, RA, Crohn's).

          4. Initiation of treatment with systemic corticosteroids (either IV or oral steroids,
             excluding inhalers) within 1 week before administration of the first dose of study
             drug

          5. Sensory or motor neuropathy ≥ Grade 2.
