Trial Outcomes & Findings for CoolSculpting in the Abdomen Using Applicator With and Without CCI (NCT NCT02787850)

NCT ID: NCT02787850

Last Updated: 2021-12-03

Results Overview

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, 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 at least 70% correct identification of pre-treatment images by two out of three reviewers.

Measure
CoolSculpting Treatment Cohort A
CoolSculpting device with and without Crown Cooling Insert and standard applicator and will be used to perform treatments on contralateral sides of the abdomen. Cohort A will receive treatments on one side of the abdomen without the Crown Cooling Insert with a protocol-defined temperature for 60 minutes. The contralateral side of the abdomen will be treated with the Crown Cooling Insert using a protocol-defined temperature for 45 minutes.
CoolSculpting Treatment Cohort B
CoolSculpting device with the Crown Cooling Insert and standard applicator and will be used to perform treatments on contralateral sides of the abdomen. Cohort B subjects will be treated one one half of the abdomen with the Crown Cooling Insert at a protocol-defined temperature for 45 minutes. The contralateral side of the abdomen will also be treated with the Cron Cooling Insert at a protocol-defined temperature for 60 minutes.

Measure
CoolSculpting Treatment Cohort A
n=10 Participants
The treatments are designed to see if fat can be reduced in the abdomen with an applicator design incorporating a new insert. Treatment duration and cooling will vary between treatment sites and cohorts. The CoolSculpting device will be used to perform treatments.
CoolSculpting Treatment Cohort B
n=10 Participants
The treatments are designed to see if fat can be reduced in the abdomen with an applicator design incorporating a new insert. Treatment duration and cooling will vary between treatment sites and cohorts. The CoolSculpting device will be used to perform treatments.

PRIMARY outcome

Timeframe: 12 weeks post treatment

Population: The analysis population consisted of 19 subjects with evaluable images. Six images from each subject's abdomen were reviewed by the independent reviewers.

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, 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 at least 70% correct identification of pre-treatment images by two out of three reviewers.

PRIMARY outcome

Timeframe: Enrollment through 12 weeks post-treatment

Population: Subjects who received CoolSculpting treatment for reduction of subcutaneous fat in the abdomen were included in the analysis population. Of the 20 subjects enrolled and treated, one subject withdrew prior to study completion.

The number of unanticipated device effects will be tabulated to assess safety of the device and applicator accessory (Crown Cooling Insert). Adverse event data is collected from the time of enrollment through the 12 week follow-up visit.

SECONDARY outcome

Timeframe: 12 weeks post-final treatment

Population: Groups include per-protocol subgroups for Cohort A and Cohort B. 20 subjects were assigned treatment parameters in Subgroup 2; one (1) subject withdrew from the study prior to completion.

Subject satisfaction with the treatment experience data will also be collected via a written questionnaire at the 12-week follow up visits. This 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 satisfied; 2) somewhat satisfied; 3) neither satisfied nor unsatisfied; 4) somewhat unsatisfied; 5) very unsatisfied.
