Overview
This study is to assess the safety and tolerability, PK characterisation, efficacy, and immunogenicity of the study intervention, and it allows assessment of the monotherapy or combination therapy of AZD6234 and AZD9550 in different sub-studies.
Description
This is a Phase Ⅱa, multi-centre, multi-drug, platform study in Chinese participants living with obesity/overweight. This platform study will consist of several sub-studies. Eligible participants will be allocated to one sub-study to receive the study intervention(s). Each sub-study will consist of a screening period, a treatment period, and a follow-up period.
Sub-study 1: AZD6234 Monotherapy This study will explore the safety, tolerability, pharmacokinetic (PK), efficacy, and immunogenicity of AZD6234 in Chinese participants with obesity/overweight, approximate 18 participants will be randomised in sub-study 1. The sub-study will comprise 3 periods totalling up to approximately 23 weeks.
