This Phase I, randomised, single-blind, placebo-controlled study has been designed to assess the safety, tolerability, and pharmacokinetics (PK) of AZD2693 following subcutaneous (SC) administration of AZD2693 in healthy participants

The study will be performed at a single study center in Japan.

The study will comprise of following periods:

• Screening Period of maximum 28 days.
• An 8-week Treatment Period during which participants will be randomized to receive multiple doses of AZD2693 or placebo at the study center.
• A Follow-up Period of 15 weeks post last dose of study intervention consisting of 8 Follow-up Visits.

Participants will be enrolled in 4 consecutive cohorts of 11 participants where 8 participants will be randomized to receive AZD2693 and 3 participants will be randomized to receive placebo.

A participant is considered to have completed the study if the participant has completed all phases of the study including the last visit.

Inclusion Criteria:

• Participants who are overtly healthy as determined by medical evaluation including medical history, physical examination, laboratory tests, and cardiac monitoring
• Participants who are of Japanese ethnicity (Japanese participant is defined as having both parents and 4 grandparents who are ethnically Japanese and this also includes second and third generation Japanese whose parents or grandparents are living in a country other than Japan)
• Participants who are of Non-Asian ethnicities. A Non-Asian Participant is defined as having both parents and grandparents who are ethnically Non-Asian.

• Any clinically important illness, medical/surgical procedure, or trauma within 4 weeks of the first dose of study intervention
• Any clinically significant cardiovascular event within the last 6 months prior to the Screening Visit
• Any clinically important abnormalities in clinical chemistry, haematology or urinalysis results and any abnormal vital signs
• Any clinically important abnormalities in rhythm, conduction or morphology of the resting electrocardiogram (ECG) and any clinically important abnormalities in the 12-Lead ECG
• Blood dyscrasias with increased risk of bleeding including idiopathic thrombocytopenic purpura and thrombotic thrombocytopenic purpura or symptoms of increased risk of bleeding
• History of major bleed or high-risk of bleeding diathesis
• Participants with a positive diagnostic nucleic acid test for Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), at Screening Visit. Participants who test positive for Coronavirus disease 2019 (COVID-19) at Screening Visit
• Participants with a significant COVID-19 illness within 6 months of enrollment
• History of severe allergy/hypersensitivity or ongoing clinically important allergy/hypersensitivity
• Received another new chemical entity (defined as a compound which has not been approved for marketing) within 30 days of last Follow-up to first dose of study intervention of this study or 5 half-lives from last dose to first dose of study intervention, whichever is the longest
• Participants who have previously received AZD2693
• Previous enrollment or randomization into the present study

The study center staff including the Investigator have to remain blinded during the clinical conduct of a given cohort with regard to study intervention (AZD2693 or placebo). The study will be blinded for all study personnel including the Investigator during the clinical conduct of the study and the Sponsor will remain blinded up to the unblinded safety review committee review of the data from the study
