Botulinum Toxin Type A for Frown Lines

Must have

Summary

This trial is testing a new treatment called AI-09 to see if it can safely and effectively reduce frown lines between the eyebrows. It focuses on people who have these lines and want to lessen their appearance.

Who is the study for?
This trial is for adults aged 20-70 with moderate to severe frown lines when contracting their forehead muscles, but none to mild at rest. Participants must not use facial treatments that affect skin during the study and women of childbearing age need a negative pregnancy test and birth control. People can't join if they have muscle weakness in the area, dry eye, recent botulinum toxin use, or conditions affecting neuromuscular function.
What is being tested?
The GL-101 trial tests AI-09 against a placebo (vehicle) in reducing glabellar (frown) lines. Participants will be randomly assigned to receive either AI-09 or a placebo treatment and will be photographed to assess changes in their frown lines over time.
What are the potential side effects?
Potential side effects may include localized reactions like pain at the injection site, headache, eyelid drooping (ptosis), dry eye symptoms due to muscle relaxation near the eyes after receiving AI-09 which is similar to other botulinum toxin products.

Other Research
The most common treatment for frown lines involves the use of neuromodulators like botulinum toxin type A. These agents work by blocking the release of acetylcholine, a neurotransmitter responsible for muscle contraction. By inhibiting acetylcholine release, these neuromodulators reduce muscle activity in the treated area, leading to a temporary relaxation of the facial muscles that cause wrinkles. This mechanism is crucial for patients with frown lines as it directly addresses the underlying cause of the wrinkles, providing a smoother and more youthful appearance.
