Could a dab of liquid under the tongue replace weekly weight-loss shots?
NCT ID NCT07728383
First seen Jul 27, 2026 · Last updated Jul 28, 2026 · Updated 1 time
Summary
This trial tests whether a liquid form of semaglutide, applied under the tongue, can help adults with obesity lose weight. Semaglutide is a hormone-like drug that reduces appetite. The study compares the liquid to a standard semaglutide tablet and a placebo. Researchers want to see if this new delivery method is safe, tolerable, and effective for weight loss over 24 weeks.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a topical-lingual liquid emulsion formulation of semaglutide, a GLP-1 receptor agonist that helps control appetite
- What this could lead to
- If successful, this could offer a new, more convenient way to deliver semaglutide for weight management without injections.
- What could go wrong
- This is a small, early proof-of-concept trial with only 40 participants. The new delivery method may not work as well as the injectable form, and side effects are still being evaluated.
