A Study to Evaluate Effect of AZD6234 in Adult Participants With Obesity or Overweight With Weight-related Comorbidity Without Type 2 Diabetes Mellitus

The study will evaluate how well AZD6234 works and how safe it is in adults with excess weight or obesity. Efficacy of AZD6234 will be compared to placebo in percent body weight change from baseline at 68 weeks of treatment

About this study

This is a Phase III, global, randomised, parallel-group, double-blind, multicentre study to assess the efficacy and safety of AZD6234 compared with placebo, administered SC once weekly in adults with obesity or overweight with at least one weight-related comorbidity without T2DM. Eligible participants will be randomized to either receive AZD6234 or matching placebo respectively.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Males & females (inclusive of all gender identities) age ≥18 years
  • BMI ≥30 kg/m2 OR BMI ≥27 kg/m2 with at least one of the following weight related comorbidities (treated or untreated): hypertension, dyslipidaemia, obstructive sleep apnoea, cardiovascular disease, heart failure, chronic kidney disease, metabolic dysfunction-associated steatotic liver disease, osteoarthritis of the knee, or stress urinary incontinence
  • Stable body weight (≤5% body weight change) for at least 3 months prior to Randomisation
  • History of at least one self-reported unsuccessful attempt to lose body weight in their lifetime

Exclusion criteria

  • Obesity primarily caused by other endocrine disorders
  • History of Type 1 or Type 2 Diabetes Mellitus, HbA1c ≥6.5% (48 mmol/mol), and/or treatment with glucose-lowering agent(s) within 3 months prior to Screening
  • Significant hepatobiliary disease and/or any of the following results at Screening:

  • AST ≥ 3.0 × ULN
  • TBL > 1.5 × ULN (except for cases of known Gilbert's Syndrome)
  • Has received treatment with a GLP-1 receptor agonist or GLP-1 containing medication for any indication within 3 months before Randomisation.

Treatment and study plan

AZD6234

Drug

IMP injected subcutaneously, once a week. Unit dose strength as per CSP.

Placebo

Drug

Placebo matching IMP dose injected subcutaneously, once a week.

Primary outcomes

  1. Percent change in body weight from baseline at 68 weeks of treatment

    Time frame: 68 weeks

    To evaluate the effect of AZD6234 as compared to placebo in percent body weight change

Secondary outcomes

  1. Absolute change in weight (kg) from baseline at 68 weeks of treatment

    Time frame: 68 weeks

    To evaluate the effect of AZD6234 as compared to placebo on absolute change in weight

  2. Achievement of at least 5 % body weight loss from baseline at 68 weeks of treatment

    Time frame: 68 weeks

    To evaluate the effect of AZD6234 as compared to placebo in body weight loss of at least 5%

  3. Achievement of at least 10% body weight loss from baseline at 68 weeks of treatment

    Time frame: 68 weeks

    To evaluate the effect of AZD6234 as compared to placebo in body weight loss of at least 10%

  4. Change in waist circumference (cm) from baseline at 68 weeks of treatment

    Time frame: 68 weeks

    To evaluate the effect of AZD6234 as compared to placebo on waist circumference change

  5. Percent change in triglycerides from baseline at 68 weeks of treatment

    Time frame: 68 weeks

    To evaluate the effect of AZD6234 as compared to placebo on triglycerides percent change

  6. Change in systolic blood pressure (mmHg) from baseline at 68 weeks of treatment

    Time frame: 68 weeks

    To evaluate the effect of AZD6234 as compared to placebo on systolic blood pressure change

  7. Percent change in fat mass from baseline at 68 weeks of treatment measured by DXA in the DXA Sub-Study subset

    Time frame: 68 weeks

    Body Composition Sub-study: To evaluate the effect of AZD6234 as compared to placebo on body composition change in the DXA subset of participants
