Treatment Arms

ArmTypeDescription
Part 1: Vemircopan, Metformin and RosuvastatinEXPERIMENTALParticipants will receive Vemircopan, Metformin and Rosuvastatin in a fixed sequence over 2 periods. Period 1 (8 days): Participants will receive a single dose of metformin on day 1 and a single dose of rosuvastatin on day 4. Period 2 (12 days): Participants will receive vemircopan twice daily from day 1 to day 11. On day 5, participants will receive metformin co-administered with vemircopan. On day 8, participants will receive rosuvastatin co-administered with vemircopan. There will be a washout period of at least 4 days between the dose of rosuvastatin in Period 1 and the first dose of vemircopan in Period 2.
Part 2: Vemircopan and LNG/EE-Containing OCsEXPERIMENTALParticipants will receive Vemircopan and LNG/EE-Containing OCs in a fixed sequence over 2 periods. Period 1 (7 days): Participants will receive a single dose of OC, consisting of LNG and EE on day 1. Period 2 (10 days): Participants will receive multiple doses of vemircopan from day 1 to day 9. On day 5, participants will receive a single dose of OC co-administered with vemircopan. There will be a washout period of at least 7 days between the dose of OC in Period 1 and the first dose of vemircopan in Period 2.
