Part 1: ALXN2050 plus FluconazoleALXN2050Period 1: Participants will receive a single dose of ALXN2050 alone and in the presence of multiple doses of fluconazole. Period 2: Participants will receive multiple doses of ALXN2050 alone and in the presence of multiple doses of fluconazole. Scheduled pharmacokinetics (PK) blood samples for both ALXN2050 and fluconazole will be collected, with a washout period of at least 14 days between the last dose of fluconazole in Period 1 and the first dose of ALXN2050 in Period 2.
