Conclusions
In conclusion, single and multiple treatments with aboBoNT-A 50 U were shown to be clinically more efficacious compared with placebo in improving the appearance of moderate to severe glabellar lines in Chinese patients. In addition, responder rates with aboBoNT-A (assessed by both the investigator and patient) were non-inferior to an active comparator at day 29 after a single injection. The results demonstrate that aboBoNT-A was well-tolerated with no new safety signals and had a rapid onset of efficacy and a long duration of effect, which were repeatable over treatment cycles.Given that limited clinical data are available on the safety and efficacy of aboBoNT-A for the treatment of moderate-to-severe glabellar lines in the Chinese population, the results from this study help to address this gap, providing clinical experience and evidence regarding the use of aboBoNT-A in China.
