Detailed Description
The study was a prospective, randomized, double-blind, placebo-controlled, parallel-group, multicenter phase 3 clinical trial. Approximately 285 females and males with moderate to severe glabellar frown lines at maximum frown were to be screened during a screening period of four months in order to randomize approximately 255 subjects into one treatment and one placebo group at a ratio of 2 : 1. After the single injection treatment with a total dose of 20 Units IncobotulinumtoxinA (Xeomin) or corresponding placebo, the subjects were observed over 120 days. During the study participation the subjects performed seven visits.
Eight (8) sites in the United States participated in this trial. The study was led by one Lead PI and a Co-Lead PI who was assisting the Lead PI. The role of the Lead PI and the Co-Lead PI was executed by one of the PIs of this study, respectively. The PI at each site was a medical doctor who was experienced in aesthetic dermatology, i.e. who had several years (>= 2 years) of experience in treatment of glabellar frown lines with BTX-A preparations. The PI was the person who led the team at one trial site and who was responsible for the conduct of the clinical trial at the site. The sub-investigator was a member of the team designated by the PI to perform important trial-related decisions. A maximum number of two sub-investigators could be authorized for injection and rating if necessary. At each site, ideally one investigator was to inject and rate all subjects. Injecting and rating sub-investigators had to be medical doctors with several years of experience in treatment of glabellar frown lines with BTX-A preparations. A subject had to be rated by the same investigator at all visits. Another phase 3 trial MRZ 60201-0724/1 (NCT00770029) with design and endpoints identical to those in this trial was performed in order to compare efficacy and safety results with a second study population.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Placebo Comparator: Placebo
Placebo to IncobotulinumtoxinA (Xeomin) powder for solution for injection; dose: one injection session of solution, prepared by reconstitution of powder with 0.9% NaCl, corresponding to total placebo volume 0.5 mL; mode of administration: intramuscular injection
|
The treatment will be administered only once at day 0 at five injection sites in the glabellar area.
Volume of Placebo equivalent to IncobotulinumtoxinA (Xeomin).
|
Experimental: IncobotulinumtoxinA (Xeomin) (20 Units)
IncobotulinumtoxinA (Xeomin), also known as 'NT 201' or 'Botulinum toxin type A (150 kD), free from complexing proteins' (active ingredient: Clostridium Botulinum neurotoxin type A free from complexing proteins) powder for solution for injection; dose: one injection session of solution, prepared by reconstitution of powder with 0.9% sodium chloride (NaCl), 20 units, total volume 0.5 mL, mode of administration: intramuscular injection
|
The treatment will be administered only once at day 0 at five injection sites in the glabellar area.
The total dose of 20 Units IncobotulinumtoxinA (Xeomin) is reconstituted in a total injection volume of 0.5 mL that is to be injected to the five sites in equal aliquots of 0.1 mL.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Composite Endpoint Treatment Success (CETS) Constituted by 2 Variables: 2-point Responders at Maximum Frown (Frown as Much as Possible) at Day 30 by Investigator's Rating on the Facial Wrinkle Scale and the Patient's Assessment on 4-point Scale
Time Frame: Baseline to Day 30
|
Composite endpoint CETS constituted by two efficacy variables:
A subject was a responder only if a 2-point improvement compared to baseline occurred simultaneously for both variables. |
Baseline to Day 30
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Responders at Rest at Day 30 by Investigator's Assessment on Facial Wrinkle Scale (FWS)
Time Frame: Baseline to Day 30
|
The investigator's assessment at rest (no muscle action in the face, no frown at all) on the four-point FWS: none = 0, mild = 1, moderate = 2, severe = 3.
A responder was defined as a subject with a rating of none = 0 or mild = 1.
|
Baseline to Day 30
|
1-point Responders at Rest at Day 30 by Patient's Assessment on 4-point Scale
Time Frame: Baseline to Day 30
|
Patient's assessment at rest (no muscle action in the face, no frown at all) on the 4-point scale in comparison to sample photos: 0 = No visible vertical line(s) at all (i.e. no visible upright line); 1 = Slightly visible vertical line(s) (i.e. slightly visible upright line); 2 = Moderate vertical line(s) with depression (i.e. upright line with deepening); 3 = Deep vertical line(s) and depression which cannot be effaced by spreading (i.e. cannot be smoothed out). A subject was a responder if a 1-point improvement occurred compared to baseline. |
Baseline to Day 30
|
Responders at Maximum Frown at Day 30 by Investigator's Rating on FWS
Time Frame: Baseline to Day 30
|
The investigator's assessment at maximum frown (frown as much as possible) on the four-point FWS: none = 0, mild = 1, moderate = 2, severe = 3.
A responder was defined as a subject with a rating of none = 0 or mild = 1.
|
Baseline to Day 30
|
1-point Responders at Maximum Frown at Day 30 by Patient's Assessment on 4-point Scale
Time Frame: Baseline to Day 30
|
Patient's assessment at maximum frown (frown as much as possible) on the 4-point scale in comparison to sample photos: 0 = No muscle action at all; 1 = Some even slight muscle action possible i.e. visible furrows; 2 = Moderately strong muscle action possible i.e. visible muscle bulges; 3 = Strong muscle action possible which may cause local pallor. A subject was a responder if a 1-point improvement occurred compared to baseline. |
