There is one clinical trial.
In the proposed study, we plan to use a genotype to phenotype strategy to study the role of the organic anion transporter, OAT3, in drug response. More specifically we will examine the contribution of OAT3 to the renal clearance of anionic drugs such as cefotaxime by studying individuals with a non-functional (or poorly-functional) variant of OAT3.
One variant (A310V) which showed increased transport of estrone sulfate compared to the common allele was identified in a single Caucasian subject. --- A310V ---
Description: Participants were stratified by their OCT3 genotype, heterozygous vs homozygous. The renal clearance of cefotaxime was measured by urine content of cefotaxime metabolites in participants after the single IV push administration of 2 grams of cefotaxime.Measure: Effect of OAT3 on Renal Secretion of Cefotaxime IV Based on Genotype Time: post dose up to 24 hours
