Drug-Drug Interaction Study Between Quinine Sulfate and Rosiglitazone
Study Details
Study Description
Brief Summary
Rosiglitazone is predominantly metabolized by cytochrome P450 (CYP) 2C8. Quinine sulfate is an inhibitor of CYP 2C8. This study will evaluate the effect of multiple doses of quinine sulfate at steady-state on the pharmacokinetics of single-dose rosiglitazone in healthy adult subjects.

Detailed Description
Rosiglitazone is predominantly metabolized by cytochrome P450 (CYP) 2C8. Quinine sulfate is an inhibitor of CYP 2C8. This study will evaluate the effect of multiple doses of quinine sulfate at steady-state on the pharmacokinetics of single-dose rosiglitazone in healthy adult subjects.
On study Day 1 after a fast of at least 10 hours, twenty four healthy, non-smoking, non-obese, non-pregnant adult volunteers between the ages of 18 and 45 will be given one oral dose of rosiglitazone (1 x 4 mg tablet). Fasting will continue for 4 hours after the dose. Blood samples will be drawn from all participants before dosing and for 24 hours post-dose at times sufficient to adequately define the pharmacokinetics of rosiglitazone. A 2 day washout period will be completed after the first dose of rosiglitazone on Day 1. On Days 4-7 all subjects will receive a dose of quinine sulfate (2 x 324 mg capsules) every 8 hours starting with the 7:15 a.m. dose on Day 4 and continuing through the 11:15 p.m. dose on Day 7. Doses of quinine sulfate on Days 4-6 will be administered without regard to meals. On the morning of Day 7 after an overnight fast of at least 10 hours, all study participants will receive co-administered doses of rosiglitazone (1 x 4 mg tablet) and quinine sulfate (2 x 324 mg capsules). Fasting will continue for 4 hours after the dose. Blood samples will be drawn from all participants before dosing and for 24 hours post-dose at times sufficient to adequately determine the pharmacokinetics of rosiglitazone. A further goal of this study is to evaluate the safety and tolerability of this regimen in healthy volunteers. Subjects will be monitored throughout participation in the study for adverse reactions to the study drug and/or procedures. Blood pressure (sitting for at least 3 minutes) and pulse will be measured prior to dosing and at 1, 2 and 3 hours after the morning dose of rosiglitazone on Days 1 and 7. Electrocardiograms (EKG) will be recorded on Day 4 before dosing of quinine sulfate and at 1, 2 and 4 hours post-dose and on Day 7 before the co-administered doses of rosiglitazone and quinine sulfate and at 1, 2 and 4 hours post-dose. All adverse events whether elicited by query, spontaneously reported, or observed by clinic staff will be evaluated by the investigator and reported in the subject's case report form.

Outcome Measures
Primary Outcome Measures
- Maximum Plasma Concentration (Cmax) of Rosiglitazone [serial pharmacokinetic blood samples drawn prior to dosing on Days 1 and 7 and then 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 10, 12, 16, 20 and 24 hours after dose administration.]
The maximum or peak concentration that rosiglitazone reaches in the plasma.
- Area Under the Concentration Versus Time Curve From Time 0 to Time t [AUC(0-t)] [serial pharmacokinetic blood samples drawn prior to dosing on Days 1 and 7 and then 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 10, 12, 16, 20 and 24 hours after dose administration.]
The area under the plasma concentration versus time curve from time 0 to the time of the last measurable concentration (t), as calculated by the linear trapezoidal rule for rosiglitazone.
- Area Under the Concentration Versus Time Curve From Time 0 Extrapolated to Infinity [AUC(0-∞)] [serial pharmacokinetic blood samples drawn prior to dosing on Days 1 and 7 and then 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 10, 12, 16, 20 and 24 hours after dose administration.]
The area under the plasma concentration versus time curve from time 0 to infinity. [AUC(0-∞)] was calculated as the sum of AUC(0-t) plus the ratio of the last measurable plasma concentration to the elimination rate constant for rosiglitazone.
