Purpura, Thrombocytopenic, Idiopathic Clinical Trial
Official title:
A Randomized, Open-Label, 4-Group, 2-Period Replicate Design Study to Evaluate Within- and Between-Subject Variability in Exposure of Two Lots of E5501 20 mg Tablets, Administered as Single Doses of 40 mg, in the Fasted and Fed Conditions to Healthy Subjects
This will be a randomized, open-label, four-group, two-period, replicate design study to evaluate the effect of food on within and between subject variability in second generation formulation 20-mg tablet strengths, Lots P01008ZZA and P01009ZZA, administered as single doses of 40mg to 84 healthy male and female subjects. The study is powered to detect both a reduction in either the within or between subject variability (coefficient of variation [CV]%) of approximately 35%.
This is a Phase 2, multi-center, double-blind, randomized, placebo-controlled, dose-ranging, parallel-group study. The PK and PK/PD relationship of AKR-501 will also be studied. Approximately 65 eligible patients will be randomized in a 3:3:3:3:1 ratio in a double-blinded fashion into one of five parallel treatment groups to receive daily doses of either AKR-501 2.5, 5, 10 or 20 mg or placebo for 28 days, respectively. Each AKR-501 dosing group will consist of 15 patients while the placebo group will consist of 5 patients. All study patients will be evaluated weekly (Days 3, 5, 7, 14, 21 and 28) for safety, efficacy, and (Days 7, 14, 21, and 28) AKR-501 pharmacokinetics while receiving study treatment with a final assessment for safety and effectiveness to be done 2 weeks after the last study dose (Day 42). ;
