Pharmacokinetic and Pharmacodynamic Study of Emixustat in Subjects With Geographic Atrophy Associated With Dry Age-Related Macular Degeneration
- Conditions
- Geographic AtrophyAge-Related Macular Degeneration
- Interventions
- Other: Placebo Tablet
- Registration Number
- NCT02130531
- Lead Sponsor
- Kubota Vision Inc.
- Brief Summary
The purpose of this study is to characterize emixustat hydrochloride pharmacokinetic and pharmacodynamic parameters in subjects with geographic atrophy associated with dry age-related macular degeneration.
- Detailed Description
This is a multi-center, randomized, masked, multiple-dose, crossover study of the pharmacokinetics of emixustat hydrochloride (HCl) in subjects with geographic atrophy (GA) associated with dry age-related macular degeneration (AMD). Subjects will receive study drug during multiple dose periods in a crossover design, and serve as their own controls. There is a 21-28 day washout period between dose periods. The final Study Exit visit is 21 to 28 days after the subject's last dose of study drug at the end of the final dosing period.
