A Phase I Study to Assess the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics and Food Effect of AZD9898

In Parts 1 and 2 of the study, each subject/patient will receive a single dose (one dose level) of AZD9898, under fasted conditions. Starting dose in part 1 (SAD in healthy subjects) is 3 mg, subsequent doses will be selected based on emerging data. In Part 3 of the study, each subject will receive one dose level of AZD9898, once daily, under fasted or fed conditions. Subjects participating in Part 3B (food effect cohort) will receive an additional administration of the same dose, on the last day to investigate the effects of food.

In Parts 1 and 2 of the study, each subject/patient will receive a single dose (one dose level) of matching placebo, under fasted conditions. In Part 3 of the study, each subject will receive one dose level of matching placebo, once daily, under fasted or fed conditions. Subjects participating in Part 3B (food effect cohort) will receive an additional administration of the same dose, on the last day to investigate the effects of food.
