Is this trial a fit for you?

Likely a good fit

Adults aged 18–65 with BMI ≥30 kg/m² who have had less than 5% weight change in the prior 3 months and who can provide informed consent.

Probably not a fit

Individuals with a history of diabetes, severe allergic disease, obesity due to non-fat related causes, recent weight loss interventions, or significant gastrointestinal disorders may not benefit from this trial.

What this trial studies

This Phase 1 trial explores multiple doses of JMT206 injected under the skin in adults ages 18 to 65 with a BMI of 30 or higher. Participants are randomly assigned to receive JMT206 or a placebo, with comparator semaglutide included as an active reference in the trial design. The study focuses on safety and tolerability over a defined dosing period, collecting information on adverse events, vital signs, and laboratory tests. The goal is to understand initial safety signals and determine suitable dose ranges for future studies. Location for enrollment is Peking University People’s Hospital in Beijing, with Shanghai JMT-Bio Inc. as the sponsor.

Why it matters

Potential benefit: If successful, participants may experience insights into the safety profile of JMT206 and potential guidance for dosing in future obesity treatments.

How similar studies have gone: Previous early-stage studies of related obesity therapies have shown safety signals can be identified in similar Phase 1 designs, but this exact combination with JMT206 is new.
