Brief Summary

The main aim of this study to compare the pharmacokinetics (PK) of two formulations of AZD4144 and assess the effect of food and omeprazole on PK of AZD4144 in healthy participants.

Detailed Description

This is an open-label, randomized, single-dose, crossover Phase I study.

The study will comprise:

1. A Screening Period of 28 days.

2. Three Residential Periods

3. A final Follow-up period within 7 to 10 days after the last dose of study drug. There will be a minimum washout period of 7 days between each AZD4144 dose.

This study includes the following 2 arms:

Arm 1 consists of 3 treatments:

1. Treatment A: AZD4144 dose 1 as tablet (under fasted condition)

2. Treatment B: AZD4144 dose 1 as tablet (under fed condition)

3. Treatment C: AZD4144 dose 1 as an oral solution (under fasted condition)

Arm 2 consists of 3 treatments:

1. Treatment D: AZD4144 dose 2 as tablet (under fasted condition)

2. Treatment E: AZD4144 dose 2 as tablet (under fed condition)

3. Treatment F: Omeprazole once daily for 4 days, followed by a single dose of omeprazole along with a single dose of AZD4144 dose 2 as tablet (under fasted condition).

The participants will be randomised to one of the following treatment sequences:

Arm 1: ABC, BCA or CAB Arm 2: DEF or EDF
