RELEASE-1: Effectiveness and Safety of EN3835 in the Treatment of EFP (Cellulite) in Women
Study Details
Study Description
Brief Summary
Subjects will be screened for study eligibility within 14 days prior to enrolling in this study. Subjects with 2 treatment areas (bilateral buttocks) with moderate or severe levels of cellulite as independently assessed by the subject using the Patient Reported Photonumeric Cellulite Severity Scale (PR-PCSS) and by the Investigator using the Clinician Reported Photonumeric Cellulite Severity Scale (CR-PCSS) will be eligible. The eligibility of the buttocks will be confirmed on Day 1. Once the eligibility of the buttocks is confirmed, subjects will be randomly assigned to a treatment group (EN3835 0.84 mg per buttock or placebo) in a 1:1 ratio within an investigational site. Each subject will receive a treatment course which consists of up to 3 treatment visits (sessions), separated by 21 days (ie, Days 1, 22, and 43). Each treatment visit will consist of 12 injections (0.3 mL per injection of EN3835 0.07 mg/injection or placebo; 0.84 mg in 3.6 mL per buttock) in each of the two buttocks for a total volume of 7.2 mL (1.68 mg). Selection of dimples to be treated in the buttocks will be at the discretion of the Investigator. End of study will occur at study day 71.

Outcome Measures
Primary Outcome Measures
- 2-level Composite Responders for the Target Buttock [Day 71]
Number of of 2-level Clinician-Reported Photonumeric Cellulite Severity Scale (CR-PCSS) / Patient-Reported Photonumeric Cellulite Severity Scale (PR-PCSS) composite responders in the target buttock at Day 71. CR-PCSS and PR-PCSS is a 5-level scale ranging from "0" (None) to "4" (Severe). A participant who missed one or two assessments of CR-PCSS and PR-PCSS at Day 71 was defined as a non-responder. A 2-level composite responder is defined as a participant with an improvement from baseline of at least 2-levels of severity in the CR-PCSS and an improvement from baseline of at least 2-levels of severity in the PR-PCSS of the target buttock.
Secondary Outcome Measures
- 1-level PR-PCSS Responders of the Target Buttock [Day 71]
Improvement in cellulite severity of the Target Buttock from baseline of at least 1-level of severity in Patient-Reported Photonumeric Cellulite Severity Scale (PR-PCSS). PR-PCSS is a 5-level scale ranging from "0" (None) to "4" (Severe).
- 2-level PR-PCSS Responders of the Target Buttock [Day 71]
Improvement in cellulite severity of the Target Buttock from baseline of at least 2-level of severity in Patient-Reported Photonumeric Cellulite Severity Scale (PR-PCSS). PR-PCSS is a 5-level scale ranging from "0" (None) to "4" (Severe).
- 1-level Composite Responders of the Target Buttock [Day 71]
Improvement in cellulite severity of the Target Buttock from baseline of at least 1-level of severity in Patient-Reported Photonumeric Cellulite Severity Scale (PR-PCSS) / Clinician-Reported Photonumeric Cellulite Severity Scale (CR-PCSS). PR-PCSS and CR-PCSS is a 5-level scale ranging from "0" (None) to "4" (Severe).
- 2-level Composite Responder of the Non-target Buttock [Day 71]
Improvement in cellulite severity of the Non-target Buttock from baseline of at least 2-levels of severity in Patient-Reported Photonumeric Cellulite Severity Scale (PR-PCSS) / Clinician-Reported Photonumeric Cellulite Severity Scale (CR-PCSS). PR-PCSS and CR-PCSS is a 5-level scale ranging from "0" (None) to "4" (Severe).
- 1-level SSRS Responders [Day 71]
Subject Self-Rating Scale (SSRS) is a measure that assesses participant satisfaction with appearance in association with cellulite on the buttocks using whole numbers on a 7-level scale that ranges from "0" (Extremely Dissatisfied) to "6" (Extremely Satisfied). A 1-level SSRS responder is defined as a participant who is at least slightly satisfied (Slightly Satisfied [4], Very Satisfied [5], or Extremely Satisfied [6]) with the appearance of the cellulite on her buttocks at Day 71.
- Change From Baseline in PR-CIS Total Score [71 Days]
Patient Reported Cellulite Impact Scale (PR-CIS) is a 6-item static questionnaire, each item is answered by a participant on a 11-level numerical rating scale that ranges from "0" (Not at all) to "10" (Extremely). The PR-CIS total score is the sum of individual item scores and can range from "0" to "60" with higher numbers reflecting a more negative impact from the cellulite. A responder was defined as a participant with a reduction in the PR-CIS total score of at least 12 from baseline at an evaluation time point. A negative change from baseline indicates an improvement in cellulite severity.
- 1-level S-GAIS Responders of Target Buttock [Day 71]
Subject Global Aesthetic Improvement Scale (S-GAIS) is a measure that assesses participant rating of cellulite appearance after treatment. This scale has 7-levels ranging from "+3" (Very Much Improved) to "-3" (Very Much Worse). Responders are defined as participants with at least ≥ 1-level improvement (Improved, Much Improved or Very Much Improved) in S-GAIS assessment of the Target Buttock.
- 2-level S-GAIS Responders of Target Buttock [Day 71]
Subject Global Aesthetic Improvement Scale (S-GAIS) is a measure that assesses participant rating of cellulite appearance after treatment. This scale has 7-levels ranging from "+3" (Very Much Improved) to "-3" (Very Much Worse). Responders are defined as participants with at least ≥ 2-level improvement (Much Improved or Very Much Improved) in S-GAIS assessment of the Target Buttock.
- PR-PCSS Rating for the Target and Non-target Buttock by Visit [Day 1 to Day 71]
The Patient-Reported Photonumeric Cellulite Severity Scale (PR-PCSS) is a 5-level photonumeric scale used by the patient (participant) to assess the severity of the participant's cellulite. The scale ratings range from "0" (None) to "4" (Severe).
- Subjects Satisfaction With Cellulite Treatment at Day 71 [Day 71]
A 1-level Subject Satisfaction responder is defined as a participant who is at least Satisfied (Satisfied [+1], or Very Satisfied [+2]) with the appearance of the cellulite on her buttocks at the Day 71 visit. A positive change indicates an improvement in cellulite.
Other Outcome Measures
- Serum Antibody Positivity by Visit [Day 1 - Day 71]
Percent of participants that are seropositive. Percentages were based on the number of subjects who had immunogenicity lab samples analyzed at the visit.
- Overall Antibody Titer Levels by Visit [Day 1 - Day 71]
Descriptive statistics were based on log10 transformation of titer levels. Titer levels were imputed as 10 before the transformation if the reported level is "<10". Only seropositive participants are summarized.
- Presence of Neutralizing Antibody (Seropositivity) at Day 71 (LOCF) by Antidrug Antibody Log Titer Quartiles [Day 71]
Q1 and Q4 are based on the ADA titer levels.

Description | Patient Reported Cellulite Impact Scale (PR-CIS) is a 6-item static questionnaire, each item is answered by a participant on a 11-level numerical rating scale that ranges from "0" (Not at all) to "10" (Extremely). The PR-CIS total score is the sum of individual item scores and can range from "0" to "60" with higher numbers reflecting a more negative impact from the cellulite. A responder was defined as a participant with a reduction in the PR-CIS total score of at least 12 from baseline at an evaluation time point. A negative change from baseline indicates an improvement in cellulite severity. |
