The dermatological treatment for reducing facial wrinkles with injectable drug Botulift (botulinum toxin type A - Laboratório Químico Farmacêutico BergamoLtd.) has a not inferior activity when compared with Botox ® (botulinum toxin - Allergan Inc.) in clinical trials.

Condition Intervention Phase
Drug: Botulift
Drug: Botox
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Investigator)

Primary Outcome Measures:
  • overall improved assessment of hyperkinetic facial lines in a state of relaxation and maximal contraction through the Honeck's scale and photographic images obtained by equipment Visia Digital Compexton Analysis (Canfield Imaging Systems, version 4.0.2) [ Time Frame: after 30 days of application ]
    The non-inferiority of T group compared to the group Co was demonstrated in evaluations in a state of relaxation and maximal contraction in the PP analysis population, because as defined for the study, the lower limits of 95% of the mean of these assessments (-2 , 7% and -5.4%) are contained within the non-inferiority limit set at -10%.

Secondary Outcome Measures:
  • Length of stay of the effect of botulinum toxin A (Test and Comparator) [ Time Frame: during the 24-week period ]
    The action of both treatments decreases over time and there is no significant difference between the two treatments.

  • Safety of both botulinum toxin A [ Time Frame: during the whole period ]
    The occurrence of adverse events was similar in both groups.

Enrollment: 192

Detailed Description:

The study will evaluate non-inferiority in clinical improvement in the intensity of expression lines over 16 weeks of drug Botulift (Laboratório Químico Farmacêutico Bergamo Ltd.) compared with Botox ® (Allergan Inc.). So that the homogeneity of the group opted to use in female patients with glabellar wrinkles grade 2 (moderate) and 3 (severe) Scale Standard Facial Wrinkles, established by Honecker et al. (2003). The first area of the face perceived in mime is the glabellar complex, located in the space between the eyebrows, wrinkles eventually show (Almeida et al., 2010).

Patients will be evaluated at each visit, the doctor Principal Investigator and digital photos of the glabellar region at maximum contraction and relaxation will be obtained using the apparatus Visia (Canfield Imaging Systems, version 4.0.2) for further analysis by random team dermatologists.
