About this study

Official title: Feasibility Study of CoolSculpting Effects on Cellulite Appearance

Evaluate the safety and feasibility effecting the appearance of cellulite on the thigh using CoolSculpting.

Conditions: Body Fat Disorder
Being tested: The ZELTIQ System

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

The ZELTIQ SystemDevice
The CoolSculpting machine will be used to perform the treatments.

Study groups in NCT04876118
Study group	Role	What they receive
Fat Reduction	Experimental	The treatments are designed to see if the appearance of cellulite can be reduced on the outer thigh. Receives: Device: The ZELTIQ System

What is being measured

The primary outcome is the main question the study is designed to answer.

Percentage of Photographs Correctly Identified by Blinded Reviewers From the Independent Physician Reviewer Panel
Photographs of the treatment area taken at baseline and 12-weeks after final treatment were assessed for visual changes. Reported here is the mean percentage (%) of correct baseline identification of images by the blinded independent reviewers.
Measured: Week 12 post final treatment (up to 24 weeks after first treatment)

Secondary outcomes (1)

Number of Participants With Device and/or Procedure Related Adverse Events (AEs) and Device-related Serious Adverse Events (SADEs)
An AE was any untoward medical occurrence, unintended disease or injury, or untoward clinical signs (including abnormal laboratory findings) in participants, whether or not considered related to treatment. A serious AE was an AE that resulted in death, serious deterioration in health, permanent impairment of a body structure/function, was life-threatening, required hospitalization or medical/surgical intervention, led to fetal distress or death, congenital abnormality, or birth defect. An adverse devise effect (ADE) was any sign, symptom, or disease determined by the Investigator to have a causal relationship or possible causal relationship with the investigational device, including any AE resulting from insufficient or inadequate instructions for use, deployment, implantation, installation, or operation, or any malfunction of the device or from use error or intentional misuse of the device. A SADE was an ADE that resulted in any of the consequences characteristic of a serious AE.
Measured: Baseline up to 36 weeks post final treatment (up to 42 weeks from first treatment)
