NCT00187655

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Effect of OAT3 on Renal Secretion of Cefotaxime IV Based on Genotype

    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.

    post dose up to 24 hours

Study Arms (1)

Cefotaxime

OTHER

Cefotaxime will be administered as a single IV push of 2 grams over 5 minutes.

Drug: Cefotaxime

Interventions

Cefotaxime will be administered as a single IV push of 2 grams over 5 minutes.

Also known as: Claforan, Cefotaxime Sodium
Cefotaxime

Eligibility Criteria

Age18 Years - 45 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Previous participation in the "SOPHIE" study;
  • Has a specific genotype for OAT3

You may not qualify if:

  • Under 18 years old or over 45 years old;
  • Pregnant (pregnancy status in female subjects will be determined by a urine pregnancy test before study drug administration);
  • They report a prior history of any allergic reaction to cephalosporin antibiotic, or severe hypersensitivity to penicillin;
  • Has a prior history of renal or hepatic dysfunction (renal and hepatic function will also be determined for each subject with prescreening blood tests);
  • Taking a medication that could confound study results (such as known substrates or inhibitors of OATs);
  • They do not consent to participate in the study.
