Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

  • Participant has a known history of cryoglobulinemia, cold urticaria, cold agglutinin disease, or paroxysmal cold hemoglobinuria.
  • Participant has a known sensitivity to cold or has any condition with a known response to cold exposure that limits blood flow to the skin, such as cold urticaria, Raynaud's disease, or Chilblains (pernio).
  • Participant with a clinically significant bleeding disorder, or concomitant use of oral or subcutaneous anticoagulants, or is taking any medication that in the investigator's opinion may significantly increase the participant's risk of bruising.
  • Participant with a history of carpal tunnel syndrome, compartment syndrome, or deep vein thrombosis in the upper or lower extremities.
  • Participant is currently taking or has taken diet pills or weight control supplements within the past 6 months.
  • Participant has any dermatological conditions, such as moderate to excessive skin laxity, infection, open wound, or scars in the location of the treatment sites that may interfere with the treatment or evaluation (stretch marks are not an exclusion).

  • Participant is lactating or has been lactating in the past 6 months.
  • Participant is unable or unwilling to comply with the study requirements.
  • Participant is currently enrolled in a clinical study of any unapproved investigational device, investigational product, or any other type of medical research judged not to be scientifically or medically compatible with this study.
  • Participant has any other condition or laboratory value that would, in the professional opinion of the investigator, potentially affect the participant's response or the integrity of the data or would pose an unacceptable risk to the participant.
  • Participant has had a non-invasive fat reduction and/or body contouring procedure in the area(s) of intended treatment within the past 12 months.
  • Participant needs to administer, or has a known history of subcutaneous injections, into the area(s) of intended treatment (e.g., cortisone, heparin, insulin) within the past 6 months.
  • Participant with known sensitivity or allergy to fructose, glycerin, isopropyl alcohol, or propylene glycol.
  • Participant with impaired peripheral circulation in the area to be treated.

Arms and Interventions

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: CoolSculpting® System
Participants underwent a single CoolSculpting® treatment session on Day 1 that was comprised of timed segments of cooling followed by 2 minutes of manual massage. Each treated arm had up to two timed segments (or cycles) in the treatment session, each treated thigh had one timed segment (or cycle) in the treatment session.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Arms With Correct Identification of Baseline Versus 12-week Treatment Images of the Upper Arms by at Least Two Out of Three Blinded, Independent Reviewers
Time Frame: Baseline (Day 1) to Week 12
Baseline versus 12-week images of the participants' left and right upper arms were assessed separately by the reviewers. Success was defined as at least 75% correct identification of the pre-treatment images of the upper arms.
Baseline (Day 1) to Week 12

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percentage of Thighs With Correct Identification of Baseline Versus 12-week Treatment Images of the Inner Thighs by at Least Two Out of Three Blinded, Independent Reviewers
Time Frame: Baseline (Day 1) to Week 12
Baseline versus 12-week images of the participants' left and right thighs were assessed separately by the reviewers. Success was defined as at least 75% correct identification of the pre-treatment images of the inner thighs.
Baseline (Day 1) to Week 12
Number of Participants With a Response of 'Satisfied' or 'Very Satisfied' for Question 1 (Overall Satisfaction) on the CoolSculpting Participant Questionnaire at the 12-week Visit for the Upper Arms
Time Frame: Week 12
Participants were asked to complete a survey upon completing the treatment to assess their level of satisfaction with the treatment. Participants selected one of five options: 'very satisfied', 'satisfied', 'neither satisfied nor dissatisfied', 'dissatisfied', or 'very dissatisfied'.
Week 12
Number of Participants With a Response of 'Satisfied' or 'Very Satisfied' for Question 1 (Overall Satisfaction) on the CoolSculpting Participant Questionnaire at the 12-week Visit for the Inner Thighs
Time Frame: Week 12
Participants were asked to complete a survey upon completing the treatment to assess their level of satisfaction with the treatment. Participants selected one of five options: 'very satisfied', 'satisfied', 'neither satisfied nor dissatisfied', 'dissatisfied', or 'very dissatisfied'.
Week 12
Change From Baseline in Mean Fat Reduction Using Caliper Measurements at Week 12 for Upper Arms
Time Frame: Baseline (Day 1) to Week 12
Caliper measurements of the treatment areas were taken at baseline and at 12-weeks post treatment. After the treatment area was identified and marked, the thickness of the fat layer was measured using a caliper at the middle of the fat bulge. For each treatment area, three measurements were taken and recorded. The average of the three measurements was calculated. A negative change from baseline indicates improvement.

Change From Baseline in Mean Fat Reduction Using Caliper Measurements at Week 12 for Inner Thighs
Time Frame: Baseline (Day 1) to Week 12
Caliper measurements of the treatment areas were taken at baseline and at 12-weeks post treatment. After the treatment area was identified and marked, the thickness of the fat layer was measured using a caliper at the middle of the fat bulge.
