Official title

Retrospective Analysis of Drug Disposition and Response-related Genotypes in Cancer Patients and Correlation With Pharmacokinetics and Pharmacodynamics Data

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This study is a retrospective one, exploring the hypothesis that a person's genotypic makeup may be associated with a clinical response or toxic effect to a drug. Genetic polymorphisms, that is, states of being able to assume different forms, that are in drug-metabolizing enzymes, transporters, and receptors may affect a patient's response to drug therapy. To date, there have been limited studies looking at a drug-metabolizing genotype (genetic makeup) or phenotype (result of the genotype's interaction with the environment). However, it is often wondered if the variations in a drug's action, that is, pharmacokinetic effect, come from the genotype phenotype relationship. Participants who entered previous clinical trials at the National Cancer Institute, as approved by the Central Institutional Review Board, may be eligible for this study. Studies for which pharmacokinetic analyses were or are being performed will be the source of the patient population. Genotyping experiments will be performed through genomic DNA isolated from stored frozen serum. The genotyping results will be compared with pharmacokinetic data and clinical outcomes. Clinical data will consist of what is obtained during the course of the principal pharmacokinetic study. The results of the retrospective analyses will provide no direct benefit to the participants.
