Primary Outcome Measures
NameTimeMethod
Percentage of Composite Responders of at Least 2-Level Improvement of SeverityBaseline, Day 71

Percentage of composite responders defined as subjects with an improvement from baseline of at least 2-levels of severity on each, the Clinician-Reported Photonumeric Cellulite Severity Scale (CR-PCSS) and Patient-Reported Photonumeric Cellulite Severity Scale (PR-PCSS), at Day 71 in the ITT population. The CR-PCSS is a photonumeric scale that was used by the Investigator to evaluate cellulite ranging from 0 (none), 1 (almost none), 2 (mild), 3 (moderate), to 4 (severe). The PR-PCSS is a photonumeric scale that was used by the subjects to evaluate cellulite ranging from 0 (none), 1 (almost none), 2 (mild), 3 (moderate), to 4 (severe). A 2-level improvement on each scale for example would represent a change from a 4 (severe) to a 2 (mild). In order to be considered a responder a subject needs to have at least a 2-level improvement on both scales.

Secondary Outcome Measures
NameTimeMethod
Percentage of Composite Responders of at Least 1-Level Improvement of SeverityBaseline, Day 71

Percentage of composite responders defined as subjects with improvement from baseline of at least 1-level of severity on each, the Clinician-Reported Photonumeric Cellulite Severity Scale (CR-PCSS) and Patient-Reported Photonumeric Cellulite Severity Scale (PR-PCSS), at Day 71 in the ITT population. The CR-PCSS is a photonumeric scale that was used by the Investigator to evaluate cellulite ranging from 0 (none), 1 (almost none), 2 (mild), 3 (moderate), to 4 (severe). The PR-PCSS is a photonumeric scale that was used by the subjects to evaluate cellulite ranging from 0 (none), 1 (almost none), 2 (mild), 3 (moderate), to 4 (severe). A 1-level improvement on each scale for example would represent a change from a 4 (severe) to a 3 (moderate). In order to be considered a responder a subject needs to have at least a 1-level improvement on both scales.

CR-PCSS Responder Analysis: 2-Levels of SeverityBaseline, Day 71

Percentage of subjects with improvement from baseline of at least 2-levels of severity on the Investigator-rated Clinician-Reported Photonumeric Cellulite Severity Scale (CR-PCSS) at Day 71.The CR-PCSS is a photonumeric scale that was used by the Investigator to evaluate cellulite ranging from 0 (none), 1 (almost none), 2 (mild), 3 (moderate), to 4 (severe). A 2-level improvement would be for example a change from 4 (severe) to 2 (mild).

CR-PCSS Responder Analysis: 1-Level of SeverityBaseline, Day 71

Percentage of subjects with improvement from baseline of at least 1-level of severity on the Investigator-rated Clinician-Reported Photonumeric Cellulite Severity Scale (CR-PCSS) at Day 71.The CR-PCSS is a photonumeric scale that was used by the investigator to evaluate cellulite ranging from 0 (none), 1 (almost none), 2 (mild), 3 (moderate), to 4 (severe). A 1-level improvement would be for example a change from 4 (severe) to 3 (moderate).

CR-PCSS Change From BaselineBaseline, Day 71

The CR-PCSS is a photonumeric scale that was used by the investigator to evaluate cellulite ranging from 0 (none), 1 (almost none), 2 (mild), 3 (moderate), to 4 (severe). Change is Day 71 study visit rating minus baseline visit; negative values indicate a lessening in cellulite severity.

PR-PCSS Responder Analysis: 2-Levels of SeverityBaseline, Day 71

Percentage of subjects with improvement from baseline of at least 2-levels of severity on the subject-rated Patient-Reported Photonumeric Cellulite Severity Scale (PR-PCSS) at Day 71.The PR-PCSS is a photonumeric scale that was used by the subject to evaluate cellulite ranging from 0 (none), 1 (almost none), 2 (mild), 3 (moderate), to 4 (severe). A 2-level improvement would be for example a change from 4 (severe) to 2 (mild).

PR-PCSS Responder Analysis: 1-Level of SeverityBaseline, Day 71

Percentage of subjects with improvement from baseline of at least 1-level of severity on the subject-rated Patient-Reported Photonumeric Cellulite Severity Scale (PR-PCSS) at Day 71.The PR-PCSS is a photonumeric scale that was used by the subject to evaluate cellulite ranging from 0 (none), 1 (almost none), 2 (mild), 3 (moderate), to 4 (severe). A 1-level improvement would be for example a change from 4 (severe) to 3 (moderate).

PR-PCSS Change From BaselineBaseline, Day 71

The PR-PCSS is a photonumeric scale that was used by the subjects to evaluate cellulite ranging from 0 (none), 1 (almost none), 2 (mild), 3 (moderate), to 4 (severe). Change is Day 71 study visit rating minus baseline visit; negative values indicate a lessening in cellulite severity.

Investigator Assessment of Improvement Based on the Investigator Global Aesthetic Improvement Scale (I-GAIS)Day 71

On Day 71, the Investigator determined the degree of improvement from baseline in the treated area using the 7-point I-GAIS. Ratings could be improved (+1), much improved (+2), or very much improved (+3), or no change (0), or worse (-1), much worse (-2) or very much worse (-3).

Subject Assessment of Improvement Based on the Subject Global Aesthetic Improvement Scale (S-GAIS)Day 71

At Day 71, subjects were asked to rate their opinion of the overall improvement of their treated area using the 7-point S-GAIS. Ratings could be improved (+1), much improved (+2), or very much improved (+3), or no change (0), or worse (-1), much worse (-2) or very much worse (-3)

Subject Satisfaction Assessment Based on the the Subject Satisfaction ScaleDay 71

At Day 71, subjects were asked to rate their satisfaction with cellulite treatment using the 5-point subject satisfaction scale. Ratings could be satisfied (+1), very satisfied (+2), neither satisfied nor dissatisfied (0), or dissatisfied (-1), very dissatisfied (-2).

Change in the Hexsel Cellulite Severity Scale (CSS) Total ScoreBaseline, Day 71

Investigator used the Hexsel CSS to assess the severity of cellulite. The total score could range from 0 (no cellulite) to 15 (extremely severe cellulite). Negative change in Hexsel CSS total score indicates an improvement in cellulite severity
