Brief Summary

This phase I trial evaluates the best dose and side effects of copper (64Cu)-DOTA-pembrolizumab positron emission tomography (PET) for the study of PD1 expression. 64Cu is a radiotracer that binds to a molecule, PD1, that is found on immune cells that are found in the tumor. PD1 is short for 'programmed cell death protein 1'. When 64Cu-DOTA-pembrolizumab is injected into the patient's bloodstream, the 64Cu-pembrolizumab travels throughout the body and sticks to any tumor that has PD1 positive immune cells. Identifying the expression of PD1 in the tumor may help assess whether patients will respond to immunotherapy, and may detect clusters of immune cells when they are still too small to be detected by other Food and Drug Administration (FDA) approved techniques.

Conditions

Hematopoietic and Lymphoid Cell Neoplasm; Malignant Solid Neoplasm

Outcome Measures

Primary Outcomes (2)

• Incidence of adverse events

  Toxicity will be graded according to the National Cancer Institute (NCI)-Common Terminology Criteria for Adverse Events version 5.0. Observed toxicities will be summarized, for all dose levels, in terms of type (organ affected or laboratory determination), severity, time of onset, duration, probable association with the study agent(s) and reversibility or outcome.

  Up to 3 days

• Dose limiting toxicity

  During the first 3 days post the administration of radiolabeled pembrolizumab

Secondary Outcomes (1)

• Detection of lesions in the body by 64Cu-DOTA-pembrolizumab positron emission tomography

  Up to 3 days

Study Arms (1)

Treatment (pembrolizumab, 64Cu-DOTA-pembrolizumab, PET)

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• All subjects must have the ability to understand and the willingness to sign a written informed consent
• Ability to undergo standard PET imaging
• Plan to be treated with immunotherapy
• Karnofsky performance status (KPS) \>= 50%
• Absolute neutrophil count (ANC) \>= 1000/mm\^3
• Platelet count \>= 50/mm\^3; platelet transfusions to help patients meet eligibility criteria are not allowed within 7 days before study enrollment
• Total bilirubin =\< 1.5 x the upper limit of normal (ULN)
• Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) =\< 3 x ULN
• Calculated creatinine clearance \>= 30 mL/min
• Woman of childbearing potential must be practicing a highly effective method of birth control consistent with local regulations regarding the use of birth control methods for subjects participating in clinical studies: e.g., established use of oral, injected or implanted hormonal methods of contraception; placement of an intrauterine device or intrauterine system; barrier methods; condom with spermicidal foam/gel/film/cream/suppository or occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/suppository; male partner sterilization; true abstinence (when this is in line with the preferred and usual lifestyle of the subject) during and after the study (6 months after the last dose of 64Cu-anti-PD1 \[pembrolizumab\]-N-hydroxysuccinimide \[NHS\]-DOTA for women)
• A man who is sexually active with a woman of childbearing potential and has not had a vasectomy must agree to use a barrier method of birth control, e.g., either condom with spermicidal foam/gel/film/cream/suppository or partner with occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/suppository, and all men must also not donate sperm during the study and for 6 months after receiving the last dose of study drug

You may not qualify if:

• Prior exposure to pembrolizumab or other anti-PD1 therapy
• Unable to tolerate PET scan
• Any condition that would, in the investigator's judgement, contraindicate the patient's participation in the clinical study due to safety concerns with clinical study procedures
• Female patients who are lactating or have a positive pregnancy test during the screening period
• Infection requiring systemic antibiotic therapy within 14 days prior to start of study treatment
• Subject is receiving concurrent chemotherapy or biologic or hormonal therapy for cancer treatment. Subject is receiving bone marrow stimulatory factors (e.g., granulocyte-macrophage colony-stimulating factor \[GM-CSF\]). Note: Concurrent use of hormones for noncancer-related conditions (e.g., insulin for diabetes) is acceptable
• Patients who have had chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study
• Vaccination with live attenuated vaccines within 4 weeks of study agent administration
• Subject is currently using or has used immunosuppressive medication within 14 days prior to the study agent administration
• Intranasal, topical, inhaled, or local steroid injections (e.g., intra-articular injection)
• Chronic systemic corticosteroids at physiologic doses not to exceed 10 mg/day of prednisone or equivalent
• Steroids as premedication for hypersensitivity reactions (e.g., infusion-related reactions, computed tomography \[CT\] scan premedication)
• Subject has plasma cell leukemia, Waldenstrom's macroglobulinemia, POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, and skin changes), or primary amyloidosis
• Subject has known chronic obstructive pulmonary disease (COPD) with a forced expiratory volume in 1 second (FEV1) \< 50% predicted normal. Note that FEV1 testing is required for patients suspected of having COPD and subjects must be excluded if FEV1 \< 50%
• Subject has known allergies, hypersensitivity, or intolerance to monoclonal antibodies or human proteins, or their excipients
