Summary

This phase 2 trial tests an experimental drug called MWN105, given as a weekly injection, in adults who are overweight or have obesity but do not have diabetes. About 120 participants will receive different doses of MWN105 or a placebo for 24 weeks. The main goal is to see how much body weight changes from the start to week 24. Researchers will also check for changes in weight, metabolic health, bone density, and safety.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
MWN105 injection, an experimental drug given as a weekly shot
What this could lead to
If it works, MWN105 could offer a new weekly injection to help people with overweight or obesity lose weight and improve related health issues.
What could go wrong
This is an early phase 2 study with only 120 participants, so results may not hold up in larger trials. The drug may cause side effects or fail to show meaningful weight loss.

Inclusion Criteria: 1. Male or female participants aged 18 to 65 years (inclusive) at the time of signing the informed consent form (ICF). 2. Body weight ≥ 70 kg (male) or ≥ 60 kg (female), with body mass index (BMI) ≥ 30 kg/m² (obesity), or 27 kg/m² ≤ BMI \< 30 kg/m² (overweight) accompanied by at least one weight-related comorbidity (e.g., hypertension, dyslipidemia, prediabetes, obstructive sleep apnea syndrome, metabolic dysfunction-associated steatotic liver disease, weight-bearing joint pain, cardiovascular disease, or polycystic ovary syndrome). 3. Self-reported or documented diet and exercise control of body weight for 12 weeks or more, with body weight change of less than 5.0% within 12 weeks prior to screening. Exclusion Criteria: 1. Known hypersensitivity to GLP-1 receptor agonists, any component of the investigational product, or history of severe allergic disease or severe drug allergy. 2. Use of medications that may affect glucose metabolism or body weight before screening, including antidiabetic drugs, systemic glucocorticoids, psychotropic drugs associated with weight change, prescription weight-loss drugs within 12 weeks, or over-the-counter weight-loss drugs/appetite suppressants within 4 weeks. 3. Clinically significant laboratory abnormalities at screening or before randomization, including: 1. ALT or AST ≥3 × ULN, or TBIL ≥1.5 × ULN. 2. eGFR \<60 mL/min/1.73 m². 3. Hemoglobin \<110 g/L in males or \<100 g/L in females. 4. Calcitonin ≥35 ng/L. 5. TSH \>6.0 or \<0.4 mIU/L. 6. Fasting triglycerides ≥5.64 mmol/L. 7. Amylase or lipase \>2 × ULN. 4. History or presence of clinically significant diseases or conditions that may affect body weight, safety, or study assessments, including: 1. Secondary or drug-induced overweight/obesity. 2. Type 1 or type 2 diabetes mellitus, or laboratory evidence of diabetes (HbA1c ≥6.5%, fasting plasma glucose ≥7.0 mmol/L, or random/2-hour OGTT plasma glucose ≥11.1 mmol/L). 3. Acute or chronic pancreatitis or pancreatic injury. 4. Gallstones or cholecystitis, except adequately treated cases without residual disease. 5. Medullary thyroid carcinoma, MEN 2A/2B, or relevant family history. 6. Previous bariatric surgery or planned procedures that may significantly affect body weight. 7. Moderate or severe depression, PHQ-9 score ≥15, severe psychiatric disorders, suicidal ideation/behavior, or suicide risk. 8. Malignancy within 5 years, except specified adequately treated localized cancers. 9. Significant cardiovascular or cerebrovascular disease within 6 months before screening/randomization. 10. Osteoporosis defined as T-score ≤-2.5 or Z-score ≤-2.0, as applicable. 11. Uncontrolled hypertension (SBP ≥160 mmHg and/or DBP ≥100 mmHg). 12. Clinically significant thyroid dysfunction. 13. Significant gastric emptying disorders or active gastrointestinal disease. 14. History of organ transplantation or awaiting transplantation. 15.
