Clinical Trial Summary

NT 201, also known as IncobotulinumtoxinA (Xeomin®/Bocouture®), is a Botulinum toxin type A preparation free of complexing proteins (150 kiloDalton). Injected into the muscle, NT201 causes a reversible local relaxation of the injected muscle. Botulinum toxin type A is used for aesthetic treatment of mimic wrinkles and in the therapy of neurologic diseases. This study will investigate the safety and efficacy (non-inferiority) of NT 201 in comparison with OnabotulinumtoxinA (Vistabel®) in the treatment of glabellar frown lines.

Intervention

Drug:
• NT 201 (IncobotulinumtoxinA (Xeomin®/Bocouture®))
NT201, also known as IncobotulinumtoxinA (Xeomin®/Bocouture®), active ingredient: Clostridium botulinum neurotoxin type A free from complexing proteins, powder for solution for injection dose, 24 units; one injection session of solution, prepared by reconstitution of powder with 0.9% Sodium Chloride (NaCl). Of the 0.6 mL total injection volume, an aliquot of 0.15 mL was administered in the procerus muscle, aliquots of 0.125 mL were administered in the medial part of the both corrugator muscles and aliquots of 0.1 mL were administered in the middle part of both corrugator muscles.
• OnabotulinumtoxinA (Vistabel®)
OnabotulinumtoxinA (Vistabel®), active ingredient: Clostridium botulinum neurotoxin type A, powder for solution for injection dose, 24 units; one injection session of solution, prepared by reconstitution of powder with 0.9% Sodium Chloride (NaCl). Of the 0.6 mL total injection volume, an aliquot of 0.15 mL was administered in the procerus muscle, aliquots of 0.125 mL were administered in the medial part of the both corrugator muscles and aliquots of 0.1 mL were administered in the middle part of both corrugator muscles.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Responder by Independent Rater's Assessment at Maximum Frown at Week 4	The Outcome Measure Data Table describes the number of responders. A subject is a responder if at least 2 out of 3 independent rater identified a response. A response is defined as an improvement of at least one point on a 4-point facial wrinkle scale from baseline to 4 weeks thereafter at maximum frown. The scale comprises the items 0 = 'none', 1 = 'mild', 2 = 'moderate', 3 = 'severe' wrinkles.	4 weeks after injection	No
Secondary	Responder by Independent Rater's Assessment at Maximum Frown at Week 12	The Outcome Measure Data Table describes the number of responders. A subject is a responder if at least 2 out of 3 independent rater identified a response. A response is defined as an improvement of at least one point on a 4-point facial wrinkle scale from baseline to 12 weeks thereafter at maximum frown. The scale comprises the items 0 = 'none', 1 = 'mild', 2 = 'moderate', 3 = 'severe' wrinkles.	12 weeks after injection	No
Secondary	Responder by Independent Rater's Assessment at Rest at Week 4	The Outcome Measure Data Table describes the number of responders. A subject is a responder if at least 2 out of 3 independent rater identified a response.
