Eligibility | Inclusion Criteria: Subjects must meet all of the following inclusion criteria to be eligible for enrollment: 1. Subjects must have recurrent endometrial cancer or other solid tumors with deficient mismatch repair system. Mismatch repair deficiency is defined by 1. Immunohistochemistry with loss of expression of one of these proteins in tumor tissue as defined by standard of care: MLH1, MSH2, MSH6 and PMS2, 2. Microstaellite (MSI) unstable by PCR per standard of care, 3. MSI high by next generation sequencing using commercial platform specifically CARIS, TEMPUS or Foundation testing. 2. Must have had prior therapy with a PD1 inhibitor, pembrolizumab or other PD1/PDL1 inhibitor with confirmed radiographic progression of disease while on pembrolizumab or other PD1/PDL1 therapy. 3. Up to 5 prior lines of therapy are allowed. 4. Prior anti-angiogenesis therapy is not allowed except for bevacizumab. Prior therapy with bevacizumab is allowed. 5. Subjects must have measurable disease based on RECIST 1.1 with at least one target lesion. 6. Subjects must have an ECOG performance status of 0-1. 7. Subjects must be age >18 years. Because no dosing or adverse event data are currently available on the use of pembrolizumab in combination with sitravatinib in subjects =18 years of age, children are excluded from this study. 8.

If elevated, patient can be eligible if evaluated by an endocrine specialist, placed on replacement therapy and deemed eligible with no current or prior autoimmune disease. 9. Subjects must have the ability to understand and the willingness to sign a written informed consent document. 10. Negative serum or urine pregnancy test at screening for women of childbearing potential. 11.

Patients with diabetes type I, vitiligo, psoriasis, hypo- or hyperthyroid disease not requiring immunosuppressive treatment are eligible. 12. Patients currently on immunosuppressive therapy except: - Intra-nasal, inhaled, topical or local steroid injections (e.g., intra-articular injection) - Steroids as premedication for hypersensitivity reaction (e.g., CT scan premedication)." - Systemic corticosteroids at physiologic doses not exceeding 10 mg/day of prednisone or equivalent 13. Patients who are pregnant or breast feeding. 14. Known history of immune-mediated colitis, inflammatory bowel disease, pneumonitis, pulmonary fibrosis. Patients who developed any grade 2 or more immune related toxicities that require discontinuation of prior immune checkpoint inhibition will be excluded. Patients with prior immune mediated myocarditis, CNS and ocular toxicities of any grade are excluded. 15. Clinically significant (i.e., active) cardiovascular disease: cerebral vascular accident/stroke (< 6 months prior to enrollment), myocardial infarction (< 6 months prior to enrollment), unstable angina, congestive heart failure (= New York Heart Association Classification Class II), or serious cardiac arrhythmia requiring medication or patients with ejection fraction < 40%. 16. Individuals with a history of a different malignancy are ineligible except for the following circumstances: Individuals with a history of other malignancies are eligible if they have been disease-free for at least 3 years and are deemed by the investigator to be at low risk for recurrence of that malignancy. Individuals with the following cancers are eligible if diagnosed and treated within the past 5 years: breast cancer in situ, cervical cancer in situ, and basal cell or squamous cell carcinoma of the skin. 17. Prior organ transplantation including allogenic stem-cell transplantation. 18. Active infection requiring intravenous systemic therapy. Oral antibiotic therapy is allowed. 19. Known hepatitis B virus (HBV) or hepatitis C virus (HCV) infection (positive HBV surface antigen or HCV RNA if anti-HCV antibody screening test positive) 20. Vaccination within 4 weeks of the first dose of treatment and while on trials is prohibited except for administration of inactivated vaccines. RNA-based (such as Moderna and Pfizer COVID-19 vaccines) and viral-vector (non-replicating vaccines, such as J&J COVID-19 vaccine) are considered safe and allowed. 21. Known prior severe hypersensitivity to investigational product or any component in its formulations, including known severe hypersensitivity reactions to monoclonal antibodies (NCI CTCAE v5 Grade = 3) 22. Persistent toxicity related to prior therapy (NCI CTCAE v. 5 Grade > 1); however, alopecia, sensory neuropathy Grade = 2, or other Grade = 2 not constituting a safety risk based on investigator's judgment are acceptable. |

Primary | Objective Response | Proportion of participants with confirmed complete response or partial response by RECIST 1.1. Per RECIST v1.1. Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm. Partial Response (PR): At least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters. | At 12 weeks | |
Secondary | Clinical Benefit | Proportion of participants with complete response, partial response and stable disease by RECIST 1.1. Per RECIST v1.1. Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm. Partial Response (PR): At least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters. Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum LD since the treatment started. | Up to 5 years | |
Secondary | Progression-free survival (PFS) | Time from first response to to treatment until documented disease progression by RECIST v1.1 or death due to any cause. Progressive Disease (PD) as defined by RECIST v1.1 for target lesions: At least a 20% increase in the sum of the LD of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions. 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). For non-target lesions, (PD): Appearance of one or more new lesions and/or unequivocal progression of existing nontarget lesions. Unequivocal progression should not normally trump target lesion status. It must be representative of overall disease status change, not a single lesion increase. | Up to 5 years | |
Secondary | Duration of Response (DOR) | Time from start of complete or partial response until documented disease progression by RECIST v1.1, or death due to any cause. Progressive Disease (PD) as defined by RECIST v1.1 for target lesions: At least a 20% increase in the sum of the LD of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions. 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). For non-target lesions, (PD): Appearance of one or more new lesions and/or unequivocal progression of existing nontarget lesions. Unequivocal progression should not normally trump target lesion status. It must be representative of overall disease status change, not a single lesion increase. | Up to 5 years | |
Secondary | Overall survival (OS) | Time from first dose of study treatment until death due to any cause. | Up to 5 years | |
Secondary | Objective response irRECIST | Proportion of participants with confirmed Complete Response (iCR) or Partial Response (iPR) by Immune-related Response Evaluation Criteria in Solid Tumors (irRECIST). Complete Response (iCR), which describes the complete disappearance of TL and Non-TL. All lymph nodes must be non-pathological in size (< 10 mm in SAD). Partial Response (iPR), which occurs when the tumor load of the TL is reduced by =30% compared to the baseline, or in the case of complete remission of the TL, when one or more Non-TL can still be distinguished. | At 12 weeks | |
Secondary | Adverse Events Related to Treatment | Adverse Events which occur from first day of treatment, characterized by type, grade and relatedness to treatment according to NCI Common Terminology Criteria for Adverse Events (CTCAE) v5.0, considered to be possibly, probably or definitely related to study treatment. | Up to 5 years |
