Overview
Brief Summary
The purpose of this Phase 1b study is to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of AKB-9778 ophthalmic solution (eye drops) administered for 7 days in adults. The study is a double-masked, multiple- ascending dose trial and will enroll four cohorts of up to 12 subjects. Dose cohorts will receive increasing doses of AKB-9778 ophthalmic solution or vehicle-matched placebo daily for 7 days. Cohort 5 will enroll subjects with open angle glaucoma or ocular hypertension who will continue current prostaglandin therapy during the study. Cohort 5 subjects will receive the maximum tolerated dose from the previous cohorts.
