A Study to Investigate the Impact of Multiple Doses of Itraconazole on AZD5004 in Healthy Participants and Multiple Doses of AZD5004 on Combined Oral Ethinyl Oestradiol and Levonorgestrel in Healthy Female Participants

The purpose of this study is to assess the impact of multiple doses of itraconazole on the pharmacokinetics (PK) of AZD5004 in healthy participants (Part A), and to assess the impact of multiple doses of AZD5004 on the PK of Combined Oral Contraceptives (COCs) in healthy female participants (Part B).

This study will be an open-label, fixed-sequence, two-part study in healthy participants.

There are 2 parts in this study:

Part A: performed in healthy male and female participants. Part B: performed in healthy female participants of non-childbearing potential.

Part A will consist of:

1. Screening period of 27 days
2. Period 1
3. Period 2
4. Period 3
5. Follow-up period of 17 to 24 days after the last AZD5004 dose

Part B will consist of:

1. Screening period of 27 days
2. Start of study period
3. Up-titration period
4. End of study period
5. Follow-up
