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

A Phase I, Randomized, Placebo-Controlled Study to Assess the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics and Food Effect of Single and Multiple Ascending Oral Doses of AZD9898 in Healthy Volunteers and Asthma Patients.

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.

Study Overview

• Status: Terminated
• Conditions: Asthma
• Intervention / Treatment: Drug: AZD9898; Drug: Matching Placebo

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.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: 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.	Drug: 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.
Placebo Comparator: 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.	Drug: Matching Placebo; 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.
