Overview
Brief Summary
This was a multiple ascending dose, randomized, double-blind study assessing the safety, tolerability, pharmacokinetics, and pharmacodynamics of danicopan in healthy participants. Four different doses (75 milligrams [mg], 200 mg, 500 mg, 800 mg) and dose-matched placebo were administered under fasted conditions.
