Brief Summary
The LIGHT-COG study is a 76-week, multicenter, randomized, double-blind, placebo-controlled, parallel-group clinical trial. A total of 420 type 2 diabetes patients with early dementia are randomized 1:1 to either the active treatment group (receiving subcutaneous injections of mazdutide weekly, with stepwise dose escalation to a maintenance dose per protocol) or the placebo group (receiving matched placebo injections). The primary objective is to evaluate the potential disease-modifying effects of mazdutide on cognitive dysfunction in type 2 diabetes.
