MT10109L in the Long-term, Open-label Treatment of Glabellar Lines (GL) and Lateral Canthal Lines (LCL)

Study MT10109L-004 is an open-label extension involving participants from studies MT10109L-001 (NCT03795922), -002 (NCT03785145), -005 (NCT03721016), and -006 (NCT03732833) (referred to as Lead-In studies). The objective is to evaluate long term safety of MT10109L. Participants will include those who completed the global lead-in studies and meet the eligibility criteria for entering this open-label extension study. Participants who meet retreatment criteria will receive MT10109L administered in the same treatment area(s) with the same number of injections and injection sites as in their lead-in studies. The safety and efficacy data from the lead-in and this open-label extension will be summarized.
