A Study to Investigate the Pharmacokinetics of Different Formulations and Safety of AZD5004 in Healthy Participants Aged 18 to 55 Years

This is a Phase I, randomized, single-dose, 2 part, 3-period, open-label study.

There will be 2 Parts (Part A and Part B). In each part, participants will be randomized to a treatment sequence in each cohort. In Period 1, participants in Part A and Part B will receive Regimen A (AZD5004 Formulation 1 [reference]). In Periods 2 and 3, participants in Part A will receive Regimen B or Regimen C (AZD5004 Formulation 5) and participants in Part B will receive Regimen D or Regimen E per assigned treatment sequence.

The study will comprise:

• A Screening Period of maximum 28 days
• 3 Treatment Periods during which participants will be resident at the Clinical Unit
• A final Follow-up Visit within 3 to 7 days after being discharged.

Main Inclusion Criteria:

• Participants suitable veins for cannulation or repeated venipuncture.
• All females must have a negative pregnancy test at the Screening Visit and on admission to the Clinical Unit.
