Summary
This completed Phase 3 study tested an investigational botulinum toxin injection called AGN-151586 against a placebo for treating moderate to severe frown lines (glabellar lines). About 160 adults in China, Taiwan, and Japan received either the active injection or a placebo into five points between the eyebrows. The study measured how well the treatment reduced wrinkle severity and monitored side effects. Results are not yet available.
