Study Type : | Interventional (Clinical Trial) |
Estimated Enrollment : | 64 participants |
Allocation: | Randomized |
Intervention Model: | Sequential Assignment |
Intervention Model Description: | For the single-dose regimen, approximately 40 healthy male or female subjects will be enrolled in 1 of 5 single-dose cohorts (designated as S1 through S5, respectively) in an ascending fashion. Each cohort will consist of 8 subjects randomized to CVN766 or placebo, whereby 6 subjects will receive a single oral dose of CVN766 suspension, and 2 subjects will receive a matching placebo suspension under overnight fasted conditions. For the multiple-dose regimen, approximately 24 healthy male and female subjects age 18 to 50 years old will be enrolled in 1 of the 3 multiple-dose cohorts (designated as M1 through M3, respectively) in an ascending fashion. The dose levels planned to be studied in the multiple-dose regimen are 45, 125, and 250 mg CVN766 for multiple-dose cohorts M1 through M3, respectively. |
