|Condition or disease||Intervention/treatment||Phase|
|Hematopoietic and Lymphoid Cell Neoplasm Malignant Solid Neoplasm||Radiation: Copper Cu 64-DOTA-pembrolizumab Biological: Pembrolizumab Procedure: Positron Emission Tomography||Phase 1|
I. To assess safety and tolerability of unlabeled pembrolizumab followed by 64Cu-tetraxetan (DOTA)-pembrolizumab positron emission tomography, at each dose level, by evaluation of toxicities including: type, frequency, severity, attribution, time course and duration.
I. Generate initial estimates of the biodistribution of the 64Cu-DOTA-pembrolizumab and the preferred dose of cold antibody.
II. Determine the dose of pre-administered unlabeled pembrolizumab that improves image quality by qualitative assessment by the radiologist of 64Cu-DOTA-pembrolizumab.
III. Evaluate the performance of 64Cu-DOTA-pembrolizumab in detecting tumor lesions.
OUTLINE: This is a dose-escalation study of 64Cu-DOTA-pembrolizumab.
Patients receive pembrolizumab intravenously (IV) over 30 minutes, and within 6 hours also receive 64Cu-DOTA-pembrolizumab via slow IV push over > 1 minute on day 0. Patients then undergo PET over 60 minutes on day 1.
After completion of study treatment, patients are followed up for 3 days.

Experimental: Treatment (pembrolizumab, 64Cu-DOTA-pembrolizumab, PET)
Patients receive pembrolizumab IV over 30 minutes, and within 6 hours also receive 64Cu-DOTA-pembrolizumab via slow IV push over > 1 minute on day 0. Patients then undergo PET over 60 minutes on day 1.
Radiation: Copper Cu 64-DOTA-pembrolizumab
Procedure: Positron Emission Tomography
- Incidence of adverse events [ Time Frame: Up to 3 days ]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.
- Dose limiting toxicity [ Time Frame: During the first 3 days post the administration of radiolabeled pembrolizumab ]
- Detection of lesions in the body by 64Cu-DOTA-pembrolizumab positron emission tomography [ Time Frame: Up to 3 days ]
