This study adopted a randomized, open-label design, aiming to preliminarily explore the weight-loss maintenance effect of MWN109 tablets when administered continuously for 24 weeks in non-diabetic overweight or obese participants.
Participants who met the inclusion criteria were randomly assigned (1:1) to either the QD or QW administration group of MWN109 tablets, with the dose grouping in the MWN109-II-WL study serving as a random stratification factor.
This study included a maximum screening period of 2 weeks, a 24-week treatment observation period, and a 2-week safety follow-up period, totaling 28 weeks. The primary endpoint was the percentage change in weight from baseline after 24 weeks of administration. The secondary endpoints included the change in weight from baseline after 24 weeks of administration, as well as the change in waist circumference from baseline.

Inclusion Criteria:

2. Participants whose weight decreased by ≥5% compared to baseline at the EOT visit of the MWN109-II-WL study.
3. Participants with a BMI \> 18.5 kg/m² at the time of the safety follow-up in the MWN109-II-WL study and at the time of randomization at Visit 2 (V2) of this study, and who were evaluated by the investigator as suitable for participating in this study.
4. Agree not to use other weight-loss drugs or treatments during the study period.
5. From the time of signing the informed consent until 3 months after the last dose of the investigational drug, the participant must have no intention of becoming pregnant and must voluntarily use effective contraceptive measures to prevent pregnancy (or ensure their partner does).

2. At the EOT visit of the MWN109-II-WL study, the fasting plasma glucose in the central laboratory was ≥ 7.0 mmol/L, or the HbA1c was ≥ 6.5%.
3. At the screening stage, the PHQ-9 questionnaire score was ≥ 15; or at the screening stage, there was a suicidal tendency or suicidal behavior, or the subject was judged to have a suicidal risk.
4. Plans to participate in another clinical study of a trial drug or device before completing all the scheduled assessments in this clinical study, or to take drugs or non-drug treatments that affect weight (excluding diet and exercise control).
