A Phase III, Double Blind, Randomised, Placebo Controlled Study To Assess The Efficacy And Safety Of A Single Treatment Of Clostridium Botulinum Toxin Type A To Improve The Appearance Of Moderate To Severe Glabellar Lines
In Brief
A Phase 3 clinical trial evaluating Botulinum toxin type A and Placebo for Moderate to Severe Glabellar Lines. Completed, enrolled 185 participants across 9 sites in 2 countries.
Detailed Summary
The purpose of this study was to demonstrate the safety and the efficacy of a single treatment of an injectable liquid form of Clostridium botulinum toxin type A haemagglutinin complex (BTX-A-HAC; hereafter referred to as BTX-A-HAC Next Generation (BTX-A-HAC NG)), used for the improvement in the appearance of moderate to severe glabellar lines (the lines between the eyebrows).

Interventions
A solution containing 50 U in 0.25 mL (200 U/mL). Each vial contained 0.625 mL of deliverable volume of solution. A volume of 0.25 mL, containing 50 U of BTX-A-HAC NG (i.e. 10 U/0.05 mL) was withdrawn from the vial into a syringe for administration. The total treatment volume (0.25 mL) was divided into five injections (0.05 mL per injection), each of which was to be administered into predefined sites across the glabellar region (two injections into each corrugator muscle and one injection into the procerus muscle).
A solution containing only the excipients of BTX-A-HAC NG (identical in appearance to the active product). Each vial contained 0.625 mL of deliverable volume of solution. A volume of 0.25 mL was withdrawn from the vial into a syringe for administration. The total treatment volume (0.25 mL) was divided into five injections (0.05 mL per injection), each of which was to be administered into predefined sites across the glabellar region (two injections into each corrugator muscle and one injection into the procerus muscle).
