Could a single shot replace two for weight loss?
NCT ID NCT04940078
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether giving two weight-loss drugs, cagrilintide and semaglutide, in one combined injection works as well as giving them separately. Forty adults with overweight or obesity received weekly injections for 22 weeks. The main goal was to see how the drugs' levels in the blood compare between the two methods.
