Trial Outcomes & Findings for CoolSculpting System (NCT NCT04506307)

NCT ID: NCT04506307

Last Updated: 2025-03-10

Results Overview

Photographs of the treatment areas (torso) taken at baseline and 12-weeks after final treatment were assessed by blinded independent reviewers to determine if the CoolSculpting treatment had the effect of improvement in the reduction of fat. The reviewers were presented with 2 series of photographs the baseline and the post final treatment series, and asked to select the series representing the baseline photographs. The order in which the photographs were presented was randomized by participant. Reported here is the percentage (%) of images that were correctly identified by at least 2 out of 3 blinded independent reviewers. Success was defined as at least 70% correct identification of the baseline images.

PRIMARY outcome

Timeframe: Week 12 post final treatment (18 weeks after first treatment)

Population: Per Protocol population consisted of participants who received 2 treatments and had a weight change of no more than 5% of total body weight at the time the 12-week assessments were performed compared to the weight obtained at the first treatment visit. In addition, participants with extensive tattoos in the treated area that could hinder the evaluation were excluded.

Photographs of the treatment areas (torso) taken at baseline and 12-weeks after final treatment were assessed by blinded independent reviewers to determine if the CoolSculpting treatment had the effect of improvement in the reduction of fat. The reviewers were presented with 2 series of photographs the baseline and the post final treatment series, and asked to select the series representing the baseline photographs. The order in which the photographs were presented was randomized by participant. Reported here is the percentage (%) of images that were correctly identified by at least 2 out of 3 blinded independent reviewers. Success was defined as at least 70% correct identification of the baseline images.

SECONDARY outcome

Timeframe: From first treatment up to Week 12 post final treatment (18 weeks after first treatment)

Population: The Safety Population consisted of all enrolled participants who received at least 1 treatment.

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 adverse event (SAE) 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 ADE was any sign, symptom, or disease that was 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 an SAE.
