Pilot Study on The Flanks of Asian Patients

Study Overview
=================
Brief Summary
-----------------
This study will evaluate CoolSculpting and the CoolCurve applicator for non-invasive fat reduction in the flanks with sharp body curvature.

Detailed Description
-----------------
The purpose of this study is to evaluate the performance of the CoolCurve+ applicator for non-invasive fat layer reduction in flanks for Asian patient population.

Eligibility Criteria
-----------------
Inclusion Criteria Male or female subjects > 18 years of age. Subjects must be of Asian descent. Subject has clearly visible fat on the flanks, which in the investigator's opinion, may benefit from the treatment. Subject has not had weight change exceeding 10 pounds in the preceding month. Subject with body mass index (BMI) up to 25. BMI is defined as weight in pounds multiplied by 703 divided by the square of the height in inches. Subject with sharp flank curvature that fits well with the CoolCurve+ applicator. Subject agrees to maintain his/her weight (i.e., within 5 pounds) by not making any major changes in their diet or lifestyle during the course of the study. Subject has read and signed a written informed consent form. Exclusion Criteria Subject has had a surgical procedure(s) in the area of intended treatment. Subject has had an invasive fat reduction procedure (e.g., liposuction, abdominoplasty, mesotherapy) in the area of intended treatment. Subject has had a non-invasive fat reduction and/or body contouring procedure in the area of intended treatment within the past 6 months. Subject needs to administer, or has a known history of subcutaneous injections into the area of intended treatment (e.g., heparin, insulin) within the past month. Subject has a known history of cryoglobulinemia, cold urticaria, or paroxysmal cold hemoglobinuria. Subject has a known history of Raynaud's disease, or any known condition with a response to cold exposure that limits blood flow to the skin. Subject has a history of bleeding disorder or is taking any medication that in the investigator's opinion may increase the subject's risk of bruising. Subject is taking or has taken diet pills or supplements for weight loss within the past month. Subject has any dermatological conditions, such as moderate to excessive skin laxity, or scars in the location of the treatment sites that may interfere with the treatment or evaluation (stretch marks is not an exclusion). Subject has an active implanted device such as a pacemaker, defibrillator, or drug delivery system Subject is pregnant or intending to become pregnant during the study period (in the next 4 months). Subject is lactating or has been lactating in the past 6 months. Subject is unable or unwilling to comply with the study requirements. Subject is currently enrolled in a clinical study of any other unapproved investigational drug or device. Any other condition or laboratory value that would, in the professional opinion of the investigator, potentially affect the subject's response or the integrity of the data or would pose an unacceptable risk to the subject.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: CoolSculpting Treatment Group<br>The single arm will include all subjects treated on each flank with the CoolSculpting System and CoolCurve+ applicator. Treatment temperature and duration are defined in the protocol. | Device: The Zeltiq System<br>* Non-invasive cooling is applied to the each flank with a defined cooling rate and duration.<br>* Other names: Lipolysis;|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Proportion of Pre-treatment Images Correctly Identified | Change in the treated vs. untreated areas will be assessed by observation of changes in surface contour and/or fat volume by an independent photo review of pre-treatment and post-treatment images of the treated areas. Reviewers will be practicing dermatologists or plastic surgeons. All reviewers will be blinded to post-treatment vs. baseline untreated area. The order in which images will be presented will be randomized; for each subject placement of the baseline and pre-treatment image will be randomized for each pair of subject images. Reviewers will be asked to select the baseline photos for each subject photo series and record selections on a data collection form. Success is defined as 70% correct identification of pre-treatment images. | Baseline and 12 weeks post-final treatment | 
| Safety of the CoolSculpting and the CoolCurve+ Applicator | The number of device- or procedure-related adverse events will be tabulated for all AEs reported continuously throughout the study, from enrollment to the final 12 week follow-up visit. | Enrollment through 12 weeks post-final treatment | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Subject Satisfaction With the Procedure | Subject satisfaction as assessed by questionnaire administered at 12-weeks post-treatment will be tabulated. The questionnaire will be composed of 5-point Likert scale questions, as well as free-text responses. Subjects will be asked to determine overall satisfaction with the treatment. The choices will be: 1) very unsatisfied; 2) somewhat unsatisfied; 3) neither unsatisfied nor satisfied; 4) somewhat satisfied; 5) very satisfied. | 12 weeks post final treatment | 
| Change in the Fat Layer Thickness | Caliper measurements will be obtained prior to treatment and at the 12-week follow-up visit to assess for changes to the fat layers in the flanks. After the treatment area is identified and marked, the thickness of fat layer will be measured using a caliper at the middle of the fat bulge. For each treatment area, three (3) measurements will be taken and recorded. The average of the three measurements will be calculated. The location of where measurements were taken will be recorded on a transparency sheet along with reference points using the subject's body landmarks (such as a mole, skin pigmentation). This transparency will be used at post treatment visit to locate the measurement sites. Results will be reported in millimeters of fat layer. | Pre-treatment and 12 weeks post-final treatment | 
| Operator Feedback | Operator performing or assisting with study procedure will complete two questionnaire at the treatment visit regarding the fit of two applicators: 1) CoolCurve+ and 2) CoolCurve The questionnaire consists of four multiple choice questions, each having a 5-point scale, with '5' representing the best and '1' the worst. | Pre-treatment/treatment day |
