A Non-inferiority Clinical Trial to Compare Efficacy and Safety of Abobotulinumtoxin A (Espad Pharmed) Versus AbobotulinumtoxinA (Dysport®, Ipsen Co.) for Correction of Moderate to Severe Glabellar Lines

Espad Pharmed146 enrolled

Overview

The aim of this study is to evaluate the efficacy and safety of AbobotulinumtoxinA (produced by Espad Pharmed Darou Co.) for correction of moderate to severe glabellar lines. Hypothesis: AbobotulinumtoxinA (produced by Espad Pharmed Darou Co.) has acceptable efficacy and safety profile for correction of moderate to severe glabellar lines. Primary Outcome: To verify the non-inferiority of the efficacy of AbobotulinumtoxinA (produced by Espad Pharmed Darou Co.) compared with AbobotulinumtoxinA (Dysport®, produced by Ipsen Co.) by percentage of responders at maximum frown at day 30 after treatment. Researchers will compare the efficacy and safety profile of AbobotulinumtoxinA (produced by Espad Pharmed Darou Co.) with AbobotulinumtoxinA (Dysport®, produced by Ipsen Co.). The study is designed as phase III, randomized, two armed, double-blind, parallel, active controlled, non-inferiority clinical trial. Participants received a total dose of 40-60 units into 3 to 5 sites. After two weeks, a touch-up intervention could be done based on physician's assessment.

The study schedule includes Visit 0 (Screening), Visit 1 (Intervention, Day 0), and Follow-up Visits 2 (Day 14), 3 (Day 30), 4 (Day 90), and 5 (Day 120). At Visit 0, informed consent is obtained, and eligibility is assessed through initial evaluations and review of inclusion and exclusion criteria. At Visit 1, subjects are randomized (1:1) and receive the investigational treatment. Full-face photographs are obtained at Visit 1 (Before receiving the investigational treatment), and at Follow-up Visits 2, 3, 4, and 5, in both resting state and maximum frown. Efficacy is evaluated at Visits 3, 4, and 5. All adverse events are Recorded at all visits.

Outcomes

Primary Outcomes

Responders at maximum frown by investigator's assessment

Percentage of responders measured by the investigator's live assessment based on Glabellar Line Severity Scale (GLSS) at maximum frown at day 30 after treatment The Glabellar Line Severity Scale (GLSS) is a 4-grade scale defined as follows: 0 = no glabellar lines, 1 = mild lines, 2 = moderate lines, 3 = severe lines. Higher scores indicate more severe glabellar lines. Participants were considered responders if they showed a reduction of at least 2 points from baseline on the scale.

Time frame: Day 30

Secondary Outcomes

Responders at rest by investigator's assessment

Percentage of responders measured by the investigator's live assessment based on Glabellar Line Severity Scale (GLSS) at rest at days 30, 90 and 120 after treatment The Glabellar Line Severity Scale (GLSS) is a 4-grade scale defined as follows: 0 = no glabellar lines, 1 = mild lines, 2 = moderate lines, 3 = severe lines. Higher scores indicate more severe glabellar lines. Participants were considered responders if they showed a reduction of at least 2 points from baseline on the scale.

Time frame: Days 30, 90 and 120

Responders at maximum frown by subject's self-assessment

Percentage of responders measured by the subject's self-assessment (SSA) at maximum frown at days 30, 90 and 120 after treatment The 4-grade subject's self-assessment scale defined as follows: 0 = no glabellar lines, 1 = mild lines, 2 = moderate lines, 3 = severe lines. Higher scores indicate more severe glabellar lines. Responders are defined as those reporting a reduction of at least 2 points from baseline.

Time frame: Day 14

Onset of action measured by the subject's self-assessment (SSA) at rest

The participants were asked to record the date on which they first noticed the onset of the product's efficacy and to inform the investigator of this date during the visit on day 14.

Time frame: Day 14

Time frame: Day 14

Safety assessment by evaluation of adverse events (AEs)

Adverse events (AEs) were assessed at all visits. All reported events were classified as mild, moderate, or severe. Moreover, seriousness of Adverse events was assessed according to International Council for Harmonization (ICH-E2B) guidelines. The causality relation was assessed based on the World Health Organization (WHO) criteria.
