Efficacy and Safety of NT 201 in the Treatment of Lateral Periorbital Wrinkles
- Conditions
- Lateral Periorbital Wrinkles
- Interventions
- Drug: IncobotulinumtoxinA (Xeomin)Drug: Placebo
- Registration Number
- NCT00541723
- Lead Sponsor
- Merz Pharmaceuticals GmbH
- Brief Summary
To investigate the efficacy and safety of incobotulinumtoxinA (Xeomin) in comparison to placebo in the treatment of moderate to severe lateral periorbital wrinkles at maximum smile and to compare two different application schemes of Xeomin. Each subject will be treated on the right and left eye area, using the same dose but different application schemes (i.e. 3 or 4 injection sites).

Group Intervention Description IncobutolinumtoxinA (Xeomin), 4-injection scheme IncobotulinumtoxinA (Xeomin) IncobotulinumtoxinA (Xeomin), also known as 'NT 201' or 'Botulinum toxin type A (150kD), free of complexing proteins' (active ingredient: Clostridium Botulinum neurotoxin Type A free of complexing proteins) powder for solution for injection; dose: one injection session of solution, prepared by reconstitution of powder with 0.9% sodium chloride (NaCl); total volume 0.24 mL per side, i.e. 4 x 0.06 mL (4 x 3 units = 12 units); mode of administration: intramuscular injection. Placebo 4-injection scheme 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; total volume 0.24 mL per side, i.e. 4 x 0.06 mL placebo solution; mode of administration: intramuscular injection. IncobotulinumtoxinA (Xeomin), 3-injection scheme IncobotulinumtoxinA (Xeomin) IncobotulinumtoxinA (Xeomin), also known as 'NT 201' or 'Botulinum toxin type A (150kD), free of complexing proteins' (active ingredient: Clostridium Botulinum neurotoxin Type A free of complexing proteins) powder for solution for injection; dose: one injection session of solution, prepared by reconstitution of powder with 0.9% sodium chloride (NaCl); total volume 0.24 mL per side, i.e. 3 x 0.08 mL (3 x 4 units = 12 units); Mode of administration: intramuscular injection. Placebo 3-injection Scheme 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; total volume 0.24 mL per side, i.e. 3 x 0.08 mL placebo solution; mode of administration: intramuscular injection.
- Primary Outcome Measures
Name Time Method Response assessed by an independent rater at maximum smile at week 4 for either eye area compared to baseline. Week 4 Responder: subjects with improvement of at least 1 point on a 4 point scale for lateral periorbital wrinkles.
- Secondary Outcome Measures
Name Time Method Response assessed by the investigator at maximum smile for either eye area compared to baseline. Weeks 2, 4, 12, and 20 Responder: subjects with improvement of at least 1 point on a 4 point scale for lateral periorbital wrinkles.
Response assessed by the subject's global assessment at maximum smile for either eye area compared to baseline. Weeks 2, 4, 12, and 20 Responder: subjects with at least a moderate improvement, i.e. a score of at least +2 on a 9 point Likert scale.
