Brief summary

To evaluate the safety of same-day CoolSculpting treatments and to assess the impact on serum lipids and liver-related tests.

Detailed description

The study will evaluate the safety of multiple same-day CoolSculpting treatments and will assess any impact on serum lips or liver-related analytes,

Interventions

Inclusion criteria

* Male or female subjects \> 18 years of age. * Subject who has been assessed to receive multiple CoolSculpting treatments on the abdomen and flanks, defined as follows: 1. Lower Abdomen - One 60 minute cycle with CoolMax, 2. Right and Left Flank - One 60 minute cycle per flank, with CoolCurve+ or CoolCore, simultaneously. * Subject has not had weight change exceeding 10 pounds in the preceding month. * Subject with body mass index (BMI) up to 30. BMI is defined as weight in pounds multiplied by 703 divided by the square of the height in inches. * Subject agrees to 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 an invasive (e.g., liposuction, mesotherapy, abdominoplasty) or 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 history of hernia in the area(s) to be treated. * Subject is pregnant or intending to become pregnant during the study period (in the next 4 months). * Subject is lactating or has been lactating during the past 3 months. * Subject is unable or unwilling to comply with the study requirements, such as blood draw. * Subject is currently enrolled in a clinical study of any other unapproved investigational drug or device. * Subject has a history of lipodosis or other confounding metabolic diseases. * Subject is taking or has taken medication within the past 3 months which may affect the metabolic function. * Patient has a history of diabetes. * 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.

Evaluation of Liver- Related Tests Over TimePre-treatment; 1 week, 4 weeks, and 12 weeks post-treatmentBlood draws will be collected pre-treatment, 1-week, 4-weeks, 12-weeks post treatment. Changes in each analyte was evaluated for consistency with normal variation and for change relative to the reference range of the component (high/low), pre-treatment versus post-treatment by an independent physician. The independent physician reviewer was provided with laboratory results and other pertinent information for each subject, including demographic, medical history, and concomitant medications. For every change in laboratory value over time, the reviewer was required to make a determination of whether the change in value represented a clinically meaningful change. In addition, for any change in a laboratory value that exceeded 25% change, or any value outside of normal range, the reviewer was required to provide a written rationale for the determination of clinical meaningfulness.

Evaluation of Liver- Related Tests Over Time

Blood draws will be collected pre-treatment, 1-week, 4-weeks, 12-weeks post treatment. Changes in each analyte was evaluated for consistency with normal variation and for change relative to the reference range of the component (high/low), pre-treatment versus post-treatment by an independent physician. The independent physician reviewer was provided with laboratory results and other pertinent information for each subject, including demographic, medical history, and concomitant medications. For every change in laboratory value over time, the reviewer was required to make a determination of whether the change in value represented a clinically meaningful change. In addition, for any change in a laboratory value that exceeded 25% change, or any value outside of normal range, the reviewer was required to provide a written rationale for the determination of clinical meaningfulness.

Time frame: Pre-treatment; 1 week, 4 weeks, and 12 weeks post-treatment

Population: Blood draws completed on 35 subjects at baseline. Two liver-related test results unavailable for 1 subject at baseline. Blood draws at the 1 week, 4 week and 12 week time periods reflect 34 subjects as one of the 35 subjects enrolled withdrew from the study. Liver-related test values were analyzed for each time point.

Pain: Assessment of Pain Scores Reported on the Day of Treatment and at 12 Weeks Post-treatment.

Pain scores are collected using a 0 (no pain) to 10 (worst possible pain) scale. Scores will be collected immediately post-treatment and at the 12 week follow-up visit.

Time frame: Treatment day and 12 week post-treatment follow-up

Population: All subjects treated with the CoolSculpting System were included in the analysis population. One (1) subject was withdrawn from the study by the investigator after treatment, therefore pain scores reflect 35 subjects analyzed.

Side Effects in Treatment Area

Clinical assessments of the skin at the treatment sites to be performed immediately post-treatment, and at the 12 week follow-up visit. Subjects will be evaluated for skin changes at the treatment sites. The scale used by clinicians for the assessments is 0 = absent, 1= minor, 2= moderate, 3= severe.

Time frame: Treatment day and 12 week post-treatment follow-up

Population: The analysis population included all subjects treated with the CoolSculpting System. 1 subject did not complete the final follow-up visit. The abdomen, left and right flanks were clinically assessed immediately post treatment and at 12 weeks. At 12 weeks, 102 treatment sites were assessed.
