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

Phase 1

Terminated

• Conditions: Asthma
• Interventions: Drug: Matching Placebo; Drug: AZD9898

• Registration Number: NCT03140072
• Lead Sponsor: AstraZeneca

Brief Summary

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.

Detailed Description

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.

Group	Intervention	Description
Placebo	Matching Placebo	In Part 1 of the study, 5 single dose cohorts are planned to be evaluated, where matching placebo will be administered. Eight subjects will participate in each cohort. Within each cohort, 2 (alternatively 3) subjects will be randomized to receive a single dose of matching placebo. Fifteen asthma patients are planned to participate in 3 cohorts in Part 2. Five patients will participate in each cohort. Within each cohort, one patient (alternatively 2 or 3 patients) will be randomized to receive a single dose of matching placebo. In Part 3, 3 dose cohorts are planned. Nine healthy subjects will participate in each cohort. Within each cohort, 3 (alternatively 4) subjects will be randomized to receive matching placebo.
AZD9898	AZD9898	In Part 1 of the study, 5 single dose cohorts are planned to be evaluated, where AZD9898 will be administered. Eight subjects will participate in each cohort. Within each cohort, 6 (alternatively 8 or 10) subjects will be randomized to receive a single dose of AZD9898. Fifteen asthma patients are planned to participate in 3 cohorts in Part 2. Five patients will participate in each cohort. Within each cohort, 4 (alternatively 6 or 8) patients will be randomized to receive a single dose of AZD9898. In Part 3, 3 dose cohorts are planned. Nine healthy subjects will participate in each cohort. Within each cohort, 6 (alternatively 8, 10 or 12) subjects will be randomized to receive AZD9898. The subjects taking part in one of the MAD cohorts under fasted conditions will also take part in Part 3B in order to explore the influence of food on the PK of AZD9898.
