A Dose-Escalation Study to Evaluate Safety, Tolerability and Pharmacokinetics of Single Doses of Q203 in Normal, Healthy, Male and Female Volunteers

Completed · Phase 1 · Has a placebo group

Conditions studied: Healthy Volunteers

In brief

Randomized, double-blind, placebo-controlled, dose-escalation study in healthy male and female volunteers. Subjects will be randomly assigned to 1 of 7 treatment cohorts (Cohorts 1 - 7) of 8 subjects each, to receive either Q203 or placebo (6 active treatment : 2 placebo) in a fasting state. Dose escalation to the next cohort may be considered when at least 6 out of 8 subjects, in a cohort, completes all procedures and none of the subjects has a clinically significant adverse event (AE) that is being followed, or at the discretion of the PI if no drug-related serious adverse events (SAEs) have occurred. A food effect cohort will be enrolled to test administration of Q203 in a fed state, at 100 mg dose level (this dose level may change based on PK analysis results). Subjects who received 100mg dose in a fasting state will return and receive the second dose, with food. Subjects will be followed up for AEs, SAE or pregnancy for 30 days postdrug administration.
