Overview

Brief Summary

The purpose of the study is to assess the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of AZD1043 following single and multiple ascending doses in healthy adult participants living with overweight and/or obesity, including participants of Japanese and Chinese descent.

Detailed Description

This is a phase 1, first time in human (FTiH) randomized, single-blind, placebo-controlled study in healthy male and female participants living with overweight and/or obesity, with female participants being of non-childbearing potential. It consists of 2 parts:

Part A (single ascending doses: SAD): This will consist of Part A1 (Global SAD (GSAD)) with 6 cohorts, Part A2 (Japanese SAD (JSAD)) with 2 cohorts and Part A3 (Chinese SAD (CSAD)) with 1 cohort.

Part B (multiple ascending doses: MAD): This will consist of Part B1 (Global MAD (GMAD)) with 3 cohorts and Part B2 (Japanese MAD (JMAD)) with 1 cohort.

Participants are only allowed to participate in one of the cohorts.

Both Part A and Part B will comprise of:

  • Screening period (up to 5 weeks).
  • Treatment period.
  • Safety follow-up period.

Inclusion Criteria

  • 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 as postmenopausal or have documentation of irreversible surgical sterilization by hysterectomy, bilateral oophorectomy, or bilateral salpingectomy.

  • For the Parts A2 and B2, participants should be Japanese (natives of Japan or Japanese Americans), 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.
  • For the Part A3, participants should be Chinese defined as having both parents and 4 grandparents who are ethnically Chinese. This includes second and third generation Chinese whose parents or grandparents are living in a country other than China.

  • Any clinically important illness, medical/surgical procedure, or trauma within 4 weeks of the first administration of study intervention.
  • Any clinically important abnormalities in laboratory values, clinical chemistry, hematology, urinalysis results, or vital signs.
