Collection of Blood From Patients With Cancer, Other Tumors, or Tumor Predisposition Syndromes for Genetic Analysis : Collection of Blood From Patients With Cancer, Other Tumors, or Tumor Predisposition Syndromes for Analysis of Genetic Differences in Drug Disposition
Background:Genetic polymorphisms in drug-metabolizing enzymes, transporters/receptors might affect an individual s response to drug therapy.Inter-individual differences in efficacy and toxicity of antitumor agents are especially important given the narrow therapeutic index of these drugs.During analysis of investigational agents, inter-individual variation in pharmacokinetics and pharmacodynamics (PK/PD) is most often noted. Genetic variation in genes encoding proteins that regulate or mediate the metabolism and transport of drugs often account for some of the wide variation seen in PK/PD, and ultimately the response to, and toxicity from, pharmaceutical agents.Objectives:To obtain and analyze the genomic DNA from patients with cancer, other tumors, and tumor predisposition syndromes on a therapeutic clinical trial.To prospectively explore correlations between genetic variants involved in inter- individual differences in drug disposition versus pharmacokinetics, pharmacodynamics, response, and toxicity endpoints in patients receiving pharmaceutical agents.To mitigate harm due to treatment with ineffective or toxicity-inducing drugs in patients where gene-drug interactions are established.Eligibility:-All individuals enrolled on IRB approved NIH Intramural Research Program (IRP) therapeutic clinical trials.Design:Exploratory study with a planned accrual of 1,100 patientsGenomic DNA will be extracted from blood samples collected from patients (patients with leukemia will have cheek swab samples collected) and genotyped using the Pharmacoscan platform (Thermo).In cases where patients carry genetic variants that are related to poor outcome or significant toxicity on a given drug, clinical recommendations will be provided where specific instructions are available in the package insert. This will apply to non-anticancer agents as well given that patients with cancer, other tumors, and tumor predisposition syndromes often receive multiple agents to manage side effects and co-morbidities.The association between variants in Pharmacoscan-covered genes will be correlated with PK/PD and clinical outcomes such as response and/or toxicity..
