Conditions

Detailed Description

  1. This study is a prospective single-center, clinical trial to be conducted at one clinical site. Up to 20 subjects will be enrolled and treated (total enrollment may be more than 20 due to screen failures) if they meet the inclusion/exclusion criteria and provide written informed consent.
  2. Duration of Study The duration from when the study opens to enrollment until completion of data analysis is anticipated to be six months
  3. Study Endpoints 3.1 Primary Endpoint: One grade improvement on Depressor Anguli Oris Scale as assessed by the Principal Investigator

Depressor Anguli Oris Scale

0-None Slight or no muscle contraction

  1. Mild Mild contraction with mild pull down of corner of the mouth
  2. Moderate Moderate muscle contraction and moderate pull down of corner of mouth
  3. Severe Severe Muscle contraction with sever pull down of corner of the mouth

3.2 Secondary Endpoints

The secondary endpoints of this clinical trial include:

  1. The Principal Investigator, sub-investigator or qualified clinician delegated by the principal investigator, will complete a Global Aesthetic Improvement Scale (Investigator Global Aesthetic Improvement Scale) assessing overall aesthetic improvement at 2 weeks, 6 weeks, and 12 weeks after the treatment visit.
  2. The subjects will complete the Global Aesthetic Improvement Scale (Subject Global Aesthetic Improvement Scale) assessing overall aesthetic improvement at 2 weeks, 6 weeks, and 12 weeks after the treatment visit.
  3. The subject will complete a Patient Satisfaction Questionnaire at 2 weeks, 6 weeks, and 12 weeks after the treatment visit.
  4. Analysis of photography to provide data on change in facial muscle contraction

4. Outcome Measures 4.1 The Global Aesthetic Improvement Scale is a 5-point scale that rates global aesthetic improvement from the pretreatment appearance. The ratings are worse, no change, improved, much improved, and very much improved. In this study both live observation and photo review are utilized by the physician or a qualified, delegated clinician and subject in order to assign a score. The Investigator Global Aesthetic Improvement Scale must be performed by the principal investigator, sub-investigator or qualified clinician delegated by the principal investigator.

5. Subject enrollment 5.1 Participant Inclusion Criteria The study population will consist of males and females aged 18 years and older who have chosen to participate in this clinical trial as evidenced by execution of the informed consent document. 10 subjects will receive treatment and 10 subjects will receive placebo.

5.1.1 Informed Consent Written informed consent will be obtained from all subjects (or their guardians or legal representatives) before any study-related procedures, including any pre-treatment screening procedures, are performed. Investigators, or delegated study personnel, may discuss the availability of the study and the possibility for entry with a potential subject without first obtaining consent. Informed consent must be obtained and documented prior to initiation of any procedures that are performed solely for the purpose of determining eligibility for research.

Investigators have ethical and legal responsibilities to ensure that the protocol is clearly explained to each subject considered for enrollment in the study. Compliance with this requirement should be documented on a written Informed Consent Form approved by the reviewing Institutional Review Board. Each Informed Consent Form will include the elements required by Food and Drug Administration regulations in 21 Code of Federal Regulations Part 50.

The Institutional Review Board approved Informed Consent Form will be signed by the study personnel obtaining consent. The subject will be given a copy of the signed Informed Consent Form. The investigative site will keep the original on file.

6. Study Drug BOTOX Cosmetic (onabotulinumtoxinA) for injection, is a sterile, vacuum-dried purified botulinum toxin type A, produced from fermentation of Hall strain Clostridium botulinum type A intended for intramuscular use. It is purified from the culture solution by dialysis and a series of acid precipitations to a complex consisting of the neurotoxin, and several accessory proteins. The complex is dissolved in sterile sodium chloride solution containing Albumin Human and is sterile filtered (0.2 microns) prior to filling and vacuum-drying.

The primary release procedure for BOTOX Cosmetic uses a cell-based potency assay to determine the potency relative to a reference standard. The assay is specific to Allergan's products BOTOX and BOTOX Cosmetic. One Unit of BOTOX Cosmetic corresponds to calculated median intraperitoneal lethal dose in mice. Due to specific details of this assay such as the vehicle, dilution scheme and laboratory protocols, Units of biological activity of BOTOX Cosmetic cannot be compared to nor converted into Units of any other botulinum toxin or any toxin assessed with any other specific assay method. The specific activity of BOTOX Cosmetic is approximately 20 Units/nanogram of neurotoxin complex.

Each vial of BOTOX Cosmetic contains either 50 Units of Clostridium botulinum type A neurotoxin complex, 0.25 mg of Albumin Human, and 0.45 mg of sodium chloride; or 100 Units of Clostridium botulinum type A neurotoxin complex, 0.5 mg of Albumin Human, and 0.9 mg of sodium chloride in a sterile, vacuum-dried form without a preservative.

7. Study Procedures and Schedule 7.1 Study Images Standardized baseline and follow-up images will be taken. To ensure consistent, reproducible study photos from baseline photographs to the follow-up photographs, Moradi MD's study specific photography guidelines and procedures should be followed.

    10. Study Treatments This study involves a treatment of either onabonulinumtoxin A or a placebo to be injected in the Depressor Anguli Oris after obtaining informed consent, screening for inclusion/exclusion, complying with standardized photography requirements, and completing pregnancy tests, if applicable.

    11. Pre-Treatment Medications For this protocol, pre-treatment medication will be at the investigator's discretion and will be documented accordingly.

    12. Subject Preparation for Treatment The investigator, sub-investigator, or delegated clinician will first identify the skin areas to which treatment is to be performed. Treatment records for all regions will be maintained in accordance with this protocol. Skin in target treatment area should be cleansed with mild cleaner. No lotion, make-up, perfume, powder, or oil should be present on the area to be treated.

    13. Treatment All study treatments will be performed by the Investigator. For the study treatment 4.5 units of Botox Cosmetic will be injected per side in three injection points. Each injection point is 1.5 units of Botox for a total of six injection point, with a total of nine units. First injection is just below and lateral to the oral commisure where the skin dimples upon activation of the Depressor Anguli Oris. The second injection is between 1st and 3rd injection points along the same oblique line. The third injection is more laterally and at the mid distance from oral commisure to Jawline, along the line of Depressor Anguli Oris

Placebo subjects will have injections in the same manner, but will be injected with Bacteriostatic 0.9% Sodium Chloride.

The subjects will be monitored during the treatment for Adverse Events.

14. Concomitant Medications All concomitant prescription, non-prescription and over-the-counter medications taken during study participation will be recorded on the appropriate study-specific data form. For this protocol, a prescription medication is defined as a medication that can be prescribed only by a properly authorized/licensed clinician.
