This study will assess the pharmacokinetics of AZD5462 film-coated tablet formulation in healthy participants.

This study will consist of six treatment periods.

A total of 16 healthy male and female participants of non-childbearing potential will be randomized in this study to ensure at least 12 evaluable participants at the end of the last treatment period.

The study will comprise of a Screening Period, six Treatment Periods, and a follow-up phone call:

• A screening period of maximum 28 days.
• Six treatment periods during which participants will be residents at the study center from Day -1 until Day 17.

Each participant will receive 6 treatments.

The following treatments will be given:-

• Treatment A: Dose A of AZD5462 film-coated tablet in a fasted state.
• Treatment B: Dose A of AZD5462 film-coated tablet in a fed state.
• Treatment C: Dose B of AZD5462 film-coated tablet in a fasted state.
• Treatment D: Dose B of AZD5462 oral solution in a fasted state.
• Treatment E: Dose C of AZD5462 film-coated tablet in a fasted state.
• Treatment F: Dose C of AZD5462 film-coated tablet in a fed state.
• A follow-up phone call will take place on Day 21 (± 1 day) to record adverse events (AEs) and concomitant medication.
