About this study

Official title: A Phase 1, Randomized, Double-Blind, Placebo-Controlled, Single-and Multiple-Ascending Dose Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of MWN109 Injection in Healthy Subjects

This study is a Phase1, randomized, double-blinded, and placebo-controlled study. In each cohort, enrolled participants will be randomized to receive either placebo or MWN109.

Read the detailed description

A total of 72 healthy volunteers are expected to be enrolled into this study. Study consists of 2 parts- Part A- Single Ascending dose (SAD) and part B- Multiple ascending dose (MAD).

The entire study duration per participant is estimated to be a maximum of 8 weeks for the single ascending dose (SAD) part and 12 weeks for the multiple ascending dose (MAD) part. The end of study is defined as the date of the last visit of the last participant in the study.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Subcutaneous single and mutiple dose in people with Overweight or Obese, run by Shanghai Minwei Biotechnology Co., Ltd at 1 site in Australia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 43 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 15 Apr 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Australia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Guitao Zhang (+86 13580782564, gt.zhang@minweibiotech.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of participants with Incidence of treatment emergent adverse events (TEAEs) following treatment administration (time frame: Part A- Up to Day 29; Part B- Up to Day 50 post first dose administration). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Apr 2025.
