A Study to Assess the Efficacy, Safety and Tolerability of AT673 Co-administered With Semaglutide in Adult Participants With Type 2 Diabetes (T2D) and Overweight or Obesity
brief summary
The goal of this clinical trial is to learn if AT673 contributes to additional weight loss and glycemic control when given with semaglutide in participants with overweight/obesity and type 2 diabetes. The main questions it aims to answer are: * To compare the effect on body weight of two doses of AT673 once-weekly versus matched placebo when concurrently administered with semaglutide once-weekly * To evaluate the effect of AT673 on glycated hemoglobin (HbA1c) * To compare the safety and tolerability of AT673 versus matched placebo when concurrently administered with semaglutide
detailed description
This is a phase 2, double-blind, placebo-controlled study. Following screening, at their baseline visit, participants will initiate treatment with semaglutide at 0.25 mg/week and follow the product labelled dose escalation schedule until reaching the dose of 1.0 mg/week. Participants will remain on this dose until the end of study (EOS) visit.
At the baseline visit, participants will be randomized in a 1:1:1 ratio to receive AT673 25 mg, or 50 mg, or matching placebo, respectively, once weekly at the same time as semaglutide.
Participants will receive AT673 / placebo injections concurrently with Semaglutide during weekly clinic visits. Treatment with the AT673 / placebo will continue through the end of 13 weeks. This will be followed by a 4-week safety follow-up. The end of study visit will be at week 17.
