Study to Assess the Safety, Tolerability, and Pharmacokinetics (Movement of Drugs Within the Body) of AZD2693 in Healthy Participants

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.
