A Study to Assess the Effects of Itraconazole, Rifampicin, and Omeprazole on Pharmacokinetics of Adavosertib

The study will include 3 arms consisting of a screening period of up to 28 days (Day -28 to Day -1), an intervention period (12 days for arm A, 17 days for arm B, and 12 days for arm C), and a follow-up end of treatment \[EOT\] visit (within 3 days after a 4-day washout period relative to the last dose of adavosertib).

Patients will receive the following 2 study interventions: a single oral dose of adavosertib alone, and a single oral dose of adavosertib administered concomitantly with itraconazole. Arm B of this study follows a non-randomised, open-label, 2-intervention design. Patients will receive the following 2 study interventions: a single oral dose of adavosertib alone, and a single oral dose of adavosertib administered concomitantly with rifampicin. Arm C of this study follows a non-randomised, open-label, 2-intervention design. Patients will receive the following 2 study interventions: a single oral dose of adavosertib alone, and a single oral dose of adavosertib administered concomitantly with omeprazole.
