Pharmacokinetic Profiling of Pembrolizumab and Nivolumab in Patients With Melanoma and/or Non-Small Cell Lung Cancer

This early phase I study collects blood samples and monitors the levels of pembrolizumab and nivolumab as they move through the body in patients with melanoma and/or non-small cell lung cancer. Pembrolizumab and nivolumab are a monoclonal antibodies that may interfere with the ability of cancer cells to grow and spread. Studying samples of blood in the laboratory from patients receiving pembrolizumab and nivolumab may help doctors learn more about the effects of pembrolizumab and nivolumab on cells. It may also help doctors understand how well patients respond to treatment. Information from this study may be used in the future to guide physicians to make dosage adjustments based on serum concentrations of drug to minimize adverse side effects and maximize the effect of the drug.
