To Estimate the Potential Effects of Repeat Doses of Darapladib on

Status Completed

Clinical Trial Summary

The potential for a drug interaction between Darapladib and Rosuvastatin is felt to be low and it would be helpful to quantify this risk in man in order to guide prescribing physicians. The primary aims of this study are to estimate the potential effects of repeat doses of Darapladib on the PK of Rosuvastatin as well as evaluating safety and tolerability. Two part approaches are planned for this study. Part A of the study will examine the effects of repeat doses Darapladib on the PK of Rosuvastatin in healthy volunteers of Caucasian descent. Based on whether a significant increase in Rosuvastatin exposure is observed in Caucasians in Part A, a decision will be made regarding whether to proceed with a conditional Part B to examine this effect in healthy volunteers of Far-East Asian descent.

In both parts, subjects will receive Rosuvastatin 10 milligrams (mg) once daily (QD) for 1 day during the first treatment period (Treatment Period 1), followed by a 4 day PK sampling period/wash-out. Subjects will then receive darapladib 160 mg QD for the next 10 days with 24-hour PK sampling on the last day (Day 14 of the study). Immediately following this, all subjects will then receive the combination of Darapladib 160 mg and Rosuvastatin 10 mg for 1 day and continued Darapladib dosing of 160 mg QD for additional 3 days (Treatment Period 2) while blood samples are collected to assess Rosuvastatin PK. Plasma samples collected on Day 15 will be analyzed for both Rosuvastatin and Darapladib concentrations.

Subjects will be required to return to the unit approximately 10 to 14 days following the last dose of study medication for a clinic visit for assessments and then will return again at 35 ±7 days following the last dose for the final follow-up visit of the study. The duration of each subject's participation in the study from screening to follow-up will be approximately three months.

Approximately 18 evaluable subjects will be enrolled in Part A and another 18 subjects will be enrolled in Part B (if conducted) to complete dosing and all assessments.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
