Obesity
Conditions
Brief summary
The purpose of the study is to compare the effect on body weight in subjects taking semaglutide injection or subjects taking Wegovy®.
Detailed description
The study will involve participants engaging in discussions with study staff regarding healthy dietary choices, strategies for increasing physical activity, and additional methods for achieving weight loss, alongside the administration of the study medication. Participants will be randomly assigned to receive either semaglutide injection or Wegovy®. The study medication will be administered via a weekly subcutaneous injection using a fine needle in the abdominal skinfold. The duration of the study will be approximately 2 years, during which participants will attend 13 clinic visits with the study physician.
Interventions
DRUGSemaglutide
The dose escalation phase, starting with 0.25mg once weekly and increasing every 4 weeks (0.5mg, 1.0mg, 1.7mg), is expected to last 16 weeks; In the dose maintenance phase, the target dose of 2.4mg was maintained for 28 weeks.Treatment duration 44 weeks.
