Study & Design

• Study Type: INTERVENTIONAL
• Study Design: SINGLE_GROUP

Primary Outcome Measures

Name	Time	Method
Independent imaging review	16 weeks	The primary effectiveness endpoint is the percent of reviews by the reviewers which either identify no clinically significant difference in fat reduction between the two sides of the abdomen, or identify greater fat reduction on the side of the abdomen treated with the CoolFlex applicator at 8 weeks post-treatment. It is expected that the percentage of reviews identifying no clinically significant difference between the two sides of the abdomen or identifying greater fat reduction on the side of the abdomen treated with the CoolFlex applicator at 8 weeks post-treatment will be at least 75%.

Secondary Outcome Measures

Name	Time	Method
Subject satisfaction	16 weeks	Subject satisfaction with the Zeltiq procedure as determined by the results of a subject satisfaction questionnaire at the 8- and 16-week follow-up visits.
Overall reduction	16 weeks	Overall reduction in the fat layer thickness on each side of the abdomen, as demonstrated by comparison of pre-treatment and 8- and 16-week post-treatment ultrasound measurements, for all evaluable subjects (i.e., adequate ultrasound imaging data sets).
