About
This phase II trial studies how well pembrolizumab works in treating patients with rare tumors that cannot be removed by surgery or have spread to other parts of the body. Monoclonal antibodies, such as pembrolizumab, may block specific proteins found on white blood cells which may strengthen the immune system and control tumor growth.
Full description
PRIMARY OBJECTIVES:
I. To obtain early indication of efficacy by evaluation of non-progression rate (NPR) at 27 weeks as defined as the percentage of patients who are alive and progression-free at 27 weeks as assessed by Response Evaluation Criteria in Solid Tumors (RECIST) version (v)1.1 or immune-related(ir)RECIST or method of tumor evaluation criteria best suitable and accepted for the tumor type evaluated in patients with advanced tumor types receiving pembrolizumab.
SECONDARY OBJECTIVES:
I. To correlate efficacy by evaluation of tumor size to programmed cell death 1 ligand 1 (PD-L1) status among patients with advanced tumor types receiving pembrolizumab.
II. To evaluate safety and tolerability of pembrolizumab in patients with advanced tumors.
III. To evaluate the percentage of patients with objective response (complete response [CR] or partial response [PR]), clinical benefit (CR, PR, or stable disease [SD] >= 4 months), progression free survival (PFS), overall survival (OS), and duration of response (DOR) as assessed by RECIST v1.1 in patients with advanced tumor types receiving pembrolizumab.
IV. To evaluate the percentage of patients with objective response (CR or PR), clinical benefit (CR, PR, or SD >= 4 months), PFS, and DOR as assessed by irRECIST in patients with advanced tumor types receiving pembrolizumab.
V. To correlate the NPR at 27 weeks (9 cycles), objective response (CR or PR), clinical benefit CR, PR, or SD >= 4 months), PFS, OS, and DOR to PD-L1 status among patients with advanced tumor types receiving pembrolizumab.
EXPLORATORY OBJECTIVES:
I. To evaluate the potential role of tumor-associated immune biomarkers for prediction of therapy effectiveness in patients with advanced tumor types receiving pembrolizumab.
II. To correlate the potential role of tumor-associated immune biomarkers for prediction of therapy effectiveness to PD-L1 status among patients with advanced tumor types receiving pembrolizumab.
III. To identify imaging characteristics associated with immunological changes in tumor following treatment with pembrolizumab.
IV. To compare tumor mutation burden and serial assessment of mutation status in biopsies obtained at baseline and progression in patients with advanced tumor types receiving pembrolizumab.
V. To evaluate patient-reported outcomes (PRO) utilizing the National Cancer Institute (NCI) Patient-Reported Outcomes of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) questionnaires.
OUTLINE:
Patients receive pembrolizumab intravenously (IV) over 30 minutes on day 1. Treatment repeats every 21 days for up to 24 months in the absence of disease progression or toxicity. Patients with clinical response or disease stabilization may continue treatment for up to an additional 12 months.
After completion of study treatment, patients are followed up at 30 days and then every 12 weeks.

Inclusion criteria
Be willing and able to provide written informed consent/assent for the trial
Have measurable disease based on RECIST 1.1 or irRECIST; only cohort 9 and 10 can have evaluable disease (non-measurable lesions); tumor lesions situated in a previously irradiated area are considered measurable if progression has been demonstrated in such lesions; patients may have bone metastatic disease evaluable according to tumor evaluation criteria best suitable and accepted for the tumor type evaluated
Have one of the following advanced (unresectable and/or metastatic) solid tumor indications that has progressed following standard therapies, where standard therapies are available:
Have failed prior treatment within 6 months of consent date
Have biopsiable disease; subjects must have at least one lesion amenable to biopsy; tumor lesions used for biopsy should not be lesions used as target lesions; in cohort 9: paraganglioma-pheochromocytoma or cohort 10, where there is prominent bony disease, biopsies may not be possible due to the nature of the disease
Be willing to provide archival tissue; if archival tissue is not available, or a newly obtained core or excisional biopsy of a tumor lesion will be obtained; newly-obtained is defined as a specimen obtained up to 6 weeks (42 days) prior to initiation of treatment on day 1; in cohort 9: paraganglioma-pheochromocytoma or cohort 10, where there is prominent bony disease, biopsies may not be possible due to the nature of the disease
Have a performance status of 0 or 1 on the Eastern Cooperative Oncology Group (ECOG) performance scale
Absolute neutrophil count (ANC) >= 1,000/mcL (performed within 28 days of treatment initiation)
Platelets >= 75,000/mcL (performed within 28 days of treatment initiation)
Hemoglobin >= 9 g/dL or >= 5.6 mmol/L without transfusion or erythropoietin (EPO) dependency (within 7 days of assessment) (performed within 28 days of treatment initiation)
Serum creatinine OR measured or calculated creatinine clearance (glomerular filtration rate [GFR] can also be used in place of creatinine or creatinine clearance [CrCl]) =< 1.5 X upper limit of normal (ULN) OR >= 60 mL/min for subject with creatinine levels > 1.5 X institutional ULN (performed within 28 days of treatment initiation)
Serum total bilirubin =< 1.5 X ULN OR direct bilirubin =< ULN for subjects with total bilirubin levels > 1.5 ULN (performed within 28 days of treatment initiation)
Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT]) and alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 2.5 X ULN OR =< 5 X ULN for subjects with liver metastases (performed within 28 days of treatment initiation)
Albumin > 2.5 mg/dL (performed within 28 days of treatment initiation)
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 28 days of treatment initiation)
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 28 days of treatment initiation)
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 use an adequate method of contraception starting with the first dose of study therapy through 120 days after the last dose of study therapy
