A Basket Trial of Pembrolizumab in Patients With Advanced Solid Tumors and Genomic Instability
This phase II trial studies how well pembrolizumab works in treating participants with cancer that has spread to other places in the body, has come back or has spread to nearby tissues or lymph nodes. Monoclonal antibodies such as, pembrolizumab, may interfere with the ability of tumor cells to grow and spread.
• Be willing and able to provide written informed consent/assent for the trial
• Have a diagnosis of a tumor with evidence of genomic instability on Clinical Laboratory Improvement Amendments (CLIA) certified genomic testing, inclusive of mutations in POLE, POLD1 for arm 1 and in BRCA1 and BRCA2 for arm 2; in arm 2, enrollment of breast and ovarian histologies will be limited to a total of 10 patients
• Have advanced cancer (metastatic, recurrent or locally advanced) and measurable disease based on Response Evaluation Criteria in Solid Tumors (RECIST) 1.1
• Be willing to provide archived tumor tissue; tissue from the most obtained core or excisional biopsy of a tumor lesion is preferred; 20 unstained slides are preferred but a minimum of 15 slides will be acceptable; if adequate tissue is not present the patient may consent to a newly obtained biopsy
• Have a performance status of 0 or 1 on the Eastern Cooperative Oncology Group (ECOG) performance scale
• Absolute neutrophil count (ANC) \>= 1,500 /mcL, performed within 10 days of treatment
• Platelets \>= 100,000 / mcL, performed within 10 days of treatment
• Hemoglobin \>= 9 g/dL or \>= 5.6 mmol/L without transfusion or erythropoietin (EPO) dependency (within 7 days of assessment), performed within 10 days of treatment
• Serum creatinine =\< 1.5 X upper limit of normal (ULN) OR Measured or calculated creatinine clearance \>= 60 mL/min for subject with creatinine levels \> 1.5 X institutional ULN (glomerular filtration rate \[GFR\] can also be used in place of creatinine or creatinine clearance \[CrCl\]), performed within 10 days of treatment
• Serum total bilirubin =\< 1.5 X ULN OR direct bilirubin =\< ULN for subjects with total bilirubin levels \> 1.5 ULN, performed within 10 days of treatment
• Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase \[SGOT\]) and alanine aminotransferase (ALT) (serum glutamic pyruvic transaminase \[SGPT\]) =\< 2.5 X ULN OR =\< 5 X ULN for subjects with liver metastases, performed within 10 days of treatment
• Albumin \>= 2.5 mg/dL, performed within 10 days of treatment
• International normalized ratio (INR) or prothrombin time (PT) =\< 1.5 X ULN unless subject is receiving anticoagulant therapy as long as PT or partial thromboplastin time (PTT) is within therapeutic range of intended use of anticoagulants, performed within 10 days of treatment
• Activated partial thromboplastin time (aPTT) =\< 1.5 X ULN unless subject is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants, performed within 10 days of treatment
• Female subject of childbearing potential should have a negative urine or serum pregnancy within 72 hours prior to receiving the first dose of study medication; if the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required
• Female subjects of childbearing potential should be willing to use 2 methods of birth control or be surgically sterile, or abstain from heterosexual activity for the course of the study through 120 days after the last dose of study medication; subjects of childbearing potential are those who have not been surgically sterilized or have not been free from menses for \> 1 year
• Male subjects should agree to abstinence or use of an adequate method of contraception starting with the first dose of study therapy through 120 days after the last dose of study therapy
