Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to assess the safety, tolerability, and pharmacokinetics of AZD0233 following single and multiple ascending dose (SAD and MAD) administration in healthy participants.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a Phase I, first time in human, single-blinded, randomized, placebo-controlled study in healthy adult male and female (of non-childbearing potential) participants performed at a single Clinical Unit.

The study will be carried out in 2 parts: Part A and Part B. Eight participants will participate in each cohort. Within each cohort, 6 participants will be randomized to receive AZD0233, and 2 participants will be randomized to receive placebo.

Part A of the study will be a sequential SAD design. Five dose levels of AZD0233 are planned to be investigated (dose 1 to dose 5), 2 (dose 3 and dose 4) of which will also be assessed in participants of Japanese descent.

Part A of the study will comprise:

* A Screening Period of maximum 26 days (Day -28 to Day -2).
* An inpatient Period of up to 7 days (Day -1 to Day 6):

* Cohorts 1A, 2A, 3A (Japanese sub-Cohort only), 4A (including a Japanese sub-Cohort), and 5A: participants will be resident at the Clinical Unit from Day -1 before study intervention administration until Day 4 (72 hours after administration of the study intervention).
* Cohort 3A \[food effect (FE)\]: Participants will be resident at the Clinical Unit from Day -1 before study intervention administration and will check-out on Day 6 (72 hours after administration of the study intervention). The impact of food intake on the PK of AZD0233 will be evaluated in the same participants in Cohort 3A after a 24-hour washout period on Day 2.

Note: Japanese sub-Cohort from Cohort 3A will not be part of the FE study.

• A Follow-up Period of 7 days after the administration of the study intervention which will consist of 1 Follow-up Visit on Day 8 for Cohorts 1A, 2A, 3A (Japanese sub-Cohort only), 4A (including a Japanese sub-Cohort), and 5A and one Follow-up Visit on Day 10 for Cohort 3A, for which participants will return to the Clinical Unit for follow-up assessments.

Part B will be a sequential MAD study. Participants will be naïve to AZD0233, i.e., will not have participated in Part A of this study. There will be 3 dose levels in 4 cohorts, including a sub-cohort of participants of Japanese descent at the highest dose.

Part B will consist of:

* A Screening Period of maximum 26 days (Day -28 to Day -2).
* An Inpatient Period of 14 days (Day -1 to Day 13): Participants will be resident at the Clinical Unit from Day -1 before study intervention administration until Day 13 (\>48 hours after administration of the last dose of study intervention in case of QD (once daily) dosing and \>36 hours after the last dose for BID (twice a day) in case of dosing).
* A Follow-up Period of 7 days after the administration of the last dose of study intervention which will consist of 2 Follow-up Visits on Day 15 and Day 17.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Healthy male and/or female participants with 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.
* Females of non-childbearing potential must be confirmed at the Screening Visit by fulfilling one of the following criteria:

1. Post-menopausal defined as amenorrhea for at least 12 months following cessation of all exogenous hormonal treatments and follicle-stimulating hormone (FSH) levels in the post-menopausal range.
2. Documentation of irreversible surgical sterilization by hysterectomy, bilateral oophorectomy, or bilateral salpingectomy but not tubal ligation.
* Sexually active fertile male participants with partners of childbearing potential must adhere to the specified contraception methods from the time of first administration of study intervention until 3 months after the study Follow-up Visit.
* Have a body mass index between 18 and 30 kg/m² inclusive and weigh at least 50 kg.

Note: For Japanese sub-Cohort minimum weight of 45 kg is acceptable.

• For the healthy Japanese sub-Cohorts: healthy Japanese participants (e.g., natives of Japan or Japanese Americans) are defined as having both parents and 4 grandparents who are Japanese. This includes healthy second and third generation participants of Japanese descent whose parents or grandparents are living in a country other than Japan.
