Can a new weight-loss drug save bones while shedding pounds?
NCT ID NCT07010432
First seen Sep 10, 2026 · Last updated Sep 11, 2026 · Updated 1 time
Summary
Researchers are studying whether the experimental drug cagrilintide can reduce bone loss in postmenopausal women with obesity who are losing weight. The trial compares cagrilintide, semaglutide, a combination of both, and placebo in 144 women aged 50 to 70. Participants receive weekly injections for about 79 weeks, and researchers measure bone density in the hip, spine, and wrist using CT scans.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- cagrilintide, an experimental amylin analogue given as a weekly injection
- What this could lead to
- If cagrilintide protects bone during weight loss, it could offer a way to lose weight without weakening bones, a concern for postmenopausal women.
- What could go wrong
- This is an early-stage trial with 144 participants, so results may not hold in larger groups. Weight-loss drugs can cause nausea and other side effects, and the bone effects are still unknown.
