Summary

This early-stage study tested whether a new drug called AGN-151586 can be safely combined with BOTOX to treat moderate to severe frown lines between the eyebrows. Researchers monitored 132 healthy adults for side effects and immune responses after a single treatment session. The goal was to check safety and see if the combination works better than BOTOX alone.
