| Experimental: Part 1: Sequence 1 Healthy, young, adult participants will receive danicopan once each Period as follows: Period 1: Danicopan administered under fed conditions. Period 2: Danicopan administered under fasted conditions. There will be a washout period of at least 7 days between the dose of danicopan in Period 1 and the dose of danicopan in Period 2. |
Drug: Danicopan
A single dose of danicopan (200 milligrams) will be administered orally.
