Official title

Effect of Genetic Variants in MATE1 and OCT3 Transporters on the Pharmacodynamics of Metformin in African Americans With Type II Diabetes Mellitus.

Brief summary

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

The current study is part of a large multi-investigator grant to look at the pharmacogenetics of a number of membrane transporters. The investigators will study individuals with particular genotypes of the human organic cation transporter, (hOCT3), and the multidrug and toxin extrusion transporter, MATE1 to test the hypothesis that genetic variation in hOCT3 and hMATE1 are associated with variation in the pharmacokinetics and/or pharmacodynamics of the antidiabetic agent, metformin.
