Intervention model single group assignment
Masking single blind (outcomes assessor)
Arm
(Active Comparator)
The Zeltiq System is a noninvasive (not breaking the skin) device that reduces fat by freezing fat cells until they break apart.
noninvasive cryolipolysis device Zeltiq
(Active Comparator)
The LipoSonix System is a noninvasive ultrasound device, which can be used to selectively target and destroy fat tissue located deep under the skin.
high intensity focused ultrasound device Liposonix

Primary Outcomes

Measure
Change in best overall cosmetic appearance (right side or left side better)rated by a blinded dermatologist from baseline to week 12
time frame: 1 hour at baseline and week 12

Eligibility Criteria

Female participants from 30 years up to 65 years old.

Inclusion Criteria: 1. Female subjects ages 30-65 years old. 2. Body mass index (BMI) between 18 and 29.99. (BMI is defined as weight in pounds multiplied by 703 divided by the square of the height in inches). 3. Subjects are in good health. 4. Willing and able to abstain from partaking in any treatment other than the study procedure (existing or new) to promote body contouring and/or weight loss during the course of study participation. 5. Subjects agree to maintain their weight (i.e. within 5 pounds) by not making any changes to diet or lifestyle during the study. 6. The subjects have the willingness and the ability to understand and provide informed consent for the use of their tissue and communicate with the investigator. Exclusion Criteria: 1.

Official title Pilot Study Comparing the Effectiveness of a Noninvasive Cryolipolysis Device vs. a High Intensity Focused Ultrasound Device for Fat Reduction: A Randomized Control Trial
Principal investigator Murad Alam, MD
Description At baseline visit, subjects who meet inclusion and exclusion criteria will be enrolled. Subjects will be randomly assigned to receive Zeltiq treatment to either their right or left flank The contralateral flank will receive Liposonix treatment. A total of three identical treatments will be completed monthly for 3 consecutive months. Subjects will return 4 weeks following the last treatment for follow up photography, measurements, and assessments. This study is a pilot study designed to determine feasibility of these procedures.
