What this trial studies

This Phase 1 study aims to evaluate the safety and efficacy of a single treatment with AGN-151586 and OnabotulinumtoxinA in adults with moderate to severe glabellar lines. Participants will receive either the active treatments or a placebo, and their responses will be assessed using the Facial Wrinkle Scale. The study focuses on understanding the adverse events associated with these injections to determine their suitability for broader use in cosmetic applications.

Who should consider this trial

Good fit: Ideal candidates are adults with moderate to severe glabellar lines who are in good health.

Not a fit: Patients with active infections or dermatological conditions at the injection sites, or those with a history of hypersensitivity to botulinum neurotoxins, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new effective treatment option for individuals seeking to reduce the appearance of glabellar lines.

How similar studies have performed: Other studies have shown success with similar botulinum toxin treatments, indicating a promising avenue for this approach.
