Long-term safety and efficacy of MBA-P01 for the treatment of glabellar lines: results from a multicenter, repeated-dose, open-label extension study

초록

Purpose Following the introduction of new type of botulinum toxin (MBA-P01), a recent phase 3 study demonstrated that MBA-P01 showed comparable efficacy and safety to onabotulinumtoxin A for reducing glabellar lines. The primary objective of this study was to evaluate the long-term safety of repeated MBA-P01 administration for the treatment of glabellar lines.Materials and methods This multicenter, single-group, repeated-dose, long-term open-label extension study evaluated repeated treatment with MBA-P01 (20 U, five treatments over 16 months), with posttreatment evaluation performed up to 52 weeks.Results Based on the safety assessment results, no specific irreversible adverse reactions were associated with the safety profile of MBA-P01. Repeated treatment with MBA-P01 was effective for a treatment duration of 3-5 months.Conclusion In conclusion, multiple cycles of treatment of glabellar lines with MBA-P01 at a dose of 20 U were well tolerated. Clinical trial registration information: This study is registered in ClincalTrials.gov (NCT05321979).
