Collection of Pharmacokinetic Samples From People With Unanticipated Response, Significant Toxicity or Concern of Future Toxicity

Collection of Pharmacokinetic and Probe Substrate Samples From Participants With Unanticipated Response, Significant Toxicity or Concern of Future Toxicity

Brief summary (registry, in English)

Background: \- Certain drugs - even when they are meant to help people - cause side effects. These are unwanted effects of the drug. There are many reasons why a drug might cause side effects in one person and not in another. It may be because of how much of the drug is in the person s blood at one time. Researchers want to study the blood of people having drug side effects to better understand why they happen. Objective: \- To obtain blood samples from participants being treated with an investigational or FDA approved drug at the NIH who are having or are anticipated to have bad side effects that are thought to be due to large amount of the drug in their blood. The samples will be used to assess the cause of the side effects. Eligibility: \- People 2 years and older who are currently enrolled in clinical trials at the NIH Intramural Research Program (IRP). Design: * Participants will give blood samples.
