Clinical Trial Summary

This is an open, randomized (randomization ratio: 1:1), multiple dose, three way, three period cross over study to assess the potential for drug drug interactions between gemigliptin (a DPP-IV inhibitor mainly metabolized by CYP3A4) and metformin in a sample of healthy Mexican volunteers, aimed to determine whether the observed lack of drug-drug interactions between gemigliptin and metformin in the Korean population is reproducible in an ethnically different population characterized by a significant difference in the frequency of CYP3A4 polymorphisms associated with decreased enzymatic activity, such as CYP3A4*1b, in comparison with Asian populations.

Clinical Trial Description

Consenting, eligible healthy adult subjects sequentially received either gemigliptin 50 mg q.d., metformin 1000 mg twice a day or gemigliptin 50 mg q.d. plus metformin 1000 mg twice a day during 3 consecutive 7 day treatment periods separated by two 5-day washout intervals, in accordance with a randomly assigned treatment sequence. Starting on the sixth treatment period day, participating subjects underwent safety assessments and repeated (24 hour) blood and urine sampling for pharmacokinetic analysis. All subjects attended to a post-study visit for final safety assessments within 8 days of study completion or early withdrawal.

Urine and plasma samples where processed to determine gemigliptin and metformin concentrations using validated analytical methods and pharmacokinetic profiles of both gemigliptin and metformin were obtained using a non-compartmental method; both the rate and degree of gemigliptin and metformin absorption resulting from their concomitant administration relative to the administration of each drug alone were assessed in search of potential pharmacokinetic interactions, Finally, a post hoc assessment of the degree and rate of the absorption of gemigliptin in the study population relative to those of a group of Korean subjects participating in phase I, repeated dose gemigliptin studies was conducted. ;
