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.
Read the detailed description
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.

What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: Day 30
Secondary outcomes (8)
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.
Measured: 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.
Measured: days 30, 90 and 120
Responders at rest by subject's self-assessment
Percentage of responders measured by the subject's self-assessment (SSA) at rest 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.

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.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Abobotulinumtoxin A (Espad Pharmed Darou Co.) and Abobotulinumtoxin A (Ipsen Co.) in people with Glabellar Lines and Glabellar Frown Lines, run by Espad Pharmed at 1 site in Iran.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 19 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 7 May 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Iran. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Responders at maximum frown by investigator's assessment (time frame: Day 30). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 May 2025; AzTrials last refreshed its copy on 8 Nov 2026.
