A Phase 2 interventional study of MWN105 1 and MWN105 2 in Overweight , Obesity, sponsored by Shanghai Minwei Biotechnology Co., Ltd. Completed at 1 site in China. Open to participants aged 18 Years to 65 Years. Per ClinicalTrials.gov, last updated 2026-09-04.
Sponsored by Shanghai Minwei Biotechnology Co., Ltd (part of Lepu Medical) · Phase 2, Interventional, and Treatment
This is a Phase 2, multicenter, randomized, double-blind, placebo-controlled study to evaluate the pharmacokinetic characteristics, efficacy, and safety of MWN105 Injection in non-diabetic participants with overweight or obesity.
Approximately 120 participants will be randomized to receive different dose levels of MWN105 Injection or matching placebo, administered subcutaneously once weekly for a total treatment duration of 24 weeks, with dose titration from 15 mg to the target dose.
The primary endpoint is the percent change from baseline in body weight at Week 24. Secondary endpoints include changes in body weight and metabolic parameters, bone mineral density, pharmacokinetic parameters, immunogenicity, and safety.
11,522 studies on the registry are indexed under Obesity; 2,033 are open to participants now.
This study's enrollment of 120 is above the median of 67 across 9,006 interventional studies indexed under Obesity.

Compared within Obesity, this study's primary condition as ClinicalTrials.gg classifies it; the registry's first condition term is Overweight. The counts are of registry records indexed under each term, refreshed daily. How we classify →
Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Exclusion Criteria:
laboratory abnormalities at screening or before randomization, including:
History or presence of clinically significant diseases or conditions that may affect body weight, safety, or study assessments, including:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.
The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).
A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.
Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

Ran from Sep 2025 to primary completion in Mar 2026, 6 months.
Of 176 industry-sponsored phase 2 interventional studies under Obesity, half reached primary completion within 12 months of starting (the median), counting those still running; a quarter within 8 and three quarters within 18. This study's 6 months is below that.
Counting every sponsor, half of 308 studies reached it within 16 months; a quarter within 10 and three quarters within 35.
