Brief summary
The overall purpose of this study is to evaluate the safety and effectiveness of an intramuscular dose of Mentor Purified Toxin for the reduction of frown lines, compared with placebo.
Detailed description
This is a Phase 3, multi-center, randomized, double-blind, placebo-controlled, two-arm, single-dose study to evaluate the safety and efficacy of Mentor Purified Toxin for the treatment of glabellar rhytides. Approximately 400 subjects will be enrolled in the study. The subjects will be randomized 3:1 (300 Mentor Purified Toxin: 100 placebo) to receive either intramuscular injections of 30 U of Mentor Purified Toxin or placebo (preservative-free saline). Injected subjects will be observed for 180 days of post treatment follow-up. Follow-up clinic visits are scheduled for post treatment days 3, 7, 14, 30, 60, 90, 120, 150, and 180. The study will be conducted at up to ten clinical sites. Safety, tolerability, clinical efficacy, onset and duration of effect will be studied during the study The effectiveness of Mentor Purified Toxin will be determined by the degree of frown line reduction, during maximum forced frown and at rest (neutral expression): * as assessed live by the study doctor, * as assessed live by the subject, and * as assessed by an independent reviewer based on subject photographs Frown lines are graded on level of severity based on this scale: Severity * Minimal (0) * Mild (1) * Moderate (2) * Severe (3)
Interventions
Subjects will receive five 0.1 mL intramuscular injections at the Day 0 Treatment Visit: two in each corrugator and one in the procerus muscle. The total treatment dose (sum of the five injections) to be administered will be 0.5 mL of the placebo (preservative-free saline).
All subjects will receive five 0.1 mL intramuscular injections (two in each corrugator and one in the procerus muscle) at each Treatment Visit. The total treatment dose (sum of the five injections) to be administered will be 30 U of PurTox. Subjects will have many Treatment Visits throughout the course of the three-year study.

Eligibility
Inclusion criteria
1. Male or female subjects who are 18 years of age or older (subjects should have an interest in the effacement of glabellar rhytides) with or without previous botulinum Toxin Type A exposure; 2. In good physical and mental health as determined by the investigator based on medical history, physical examination, and/or clinical laboratory tests; 3. Noticeable presence of the glabellar rhytides for a period of 6 months or longer; 4. Score at least a 2 (moderate severity) at baseline screening on the investigator's and subject's assessments (reference photographs provided) at forced frown; and 5. Capable of understanding and complying with the protocol and must have signed the informed consent document prior to performance of any study-related procedures.
Exclusion criteria
1. History of psychiatric problems that, in the investigator's opinion, is severe enough potentially to interfere with subject outcomes; 2. History of autoimmune disease, that, in the opinion of the investigator, might interfere with subject outcomes (e.g., osteoarthritis is not considered an
