Brief summary

This study aims to generate data that conveys participant's experiences such as their satisfaction with treatment delivered by the redesigned CoolSculpting® Elite system for non-invasive fat reduction in the midsection area (abdomen and flanks) in addition to optional body areas of upper arms, inner thighs, outer thighs and/or submental area. By doing this, the study will provide insights for doctors to better inform participants about the expected outcomes when one or more body areas are considered for treatment.

Interventions

DEVICECoolSculpting® Elite System with CoolSculpting® Elite applicators

A treatment session is comprised of timed segments of cooling (treatment cycles) followed by 2 minutes of manual massage.

Inclusion criteria

Inclusion Criteria: * Participant must be in good health as determined by medical history, physical examination, vital signs, and investigator's judgment, including no known active pandemic infection. * Participant has clearly visible and palpable fat in the abdomen and flanks, and participant may also be assessed for visible and palpable fat in one or more of the following body areas: left and right lower aspects of the upper arms, left and right inner thigh, left and right outer thigh, or submental area, which in the investigator's opinion is appropriate for and may benefit from treatment. * Participant has a BMI of ≥ 18.5 and \< 30. BMI is defined as weight in kilograms divided by height in meters squared (kg/m2). * Participant agrees to maintain weight (ie, within 5% of body weight) by not making any changes in diet or exercise routine during the course of the study. * Participant agrees to have photographs taken of the treatment area(s) during the scheduled time periods.

An AE will be considered a TEAE if the AE began or worsened (increased in severity or became serious) on or after the date (and time, if known) of the first dose of study intervention. An AE will be considered a TESAE if it is a TEAE that additionally meets any SAE criterion. TEADE is defined as any TEAE with a reasonable possibility (Possible, Probable, or Causal relationship) that the event may have been caused by the study device. SADE is an ADE that might have led to any SAE consequences if a suitable action had not been taken or intervention had not been made.

Time frame: First treatment to Follow-up/Exit Visit (Week 12 + 14 days for those participants who received only 1 treatment session and Week 20 + 14 days for those participants who received 2 treatment sessions)

Population: Safety Population consisted of all enrolled participants who received at least one cryolipolysis treatment cycle (started or completed). AEs are reported separately for each of the two treatment sessions.
