In this integrated, multi-part, Phase I study, the safety, tolerability, food effect, pharmacokinetic (PK) and pharmacodynamic (PD) properties of single and repeated doses of AZD9898 will be investigated.
This study will be a Phase I, randomized, placebo-controlled study in healthy subjects and asthma patients, performed at 2 study centers. The study will consist of 3 parts (Part 1 \[SAD in healthy subjects\]; Part 2 \[SAD in asthma patients\]; Part 3 \[MAD in healthy subjects under fasted conditions, with one cohort participating under fed conditions during one day as well\]). The SAD cohorts in Parts 1 and 2 of the study will include male and women of non-childbearing potential (WONCBP) until the exposure limit for males has been reached. If an additional cohort for Parts 1 and 2 with a dose exceeding exposure limits in males is warranted (to explore the upper end of the dose response curve), this will be conducted in WONCBP only. Cohorts in Part 3 will include male subjects and WONCBP, depending on recruitment feasibility. All cohorts in the study will be single-blinded.

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.
