ZELTIQ Clinical Studies
Note:
When the flank, abdomen, and thigh studies were performed, the degree of cooling or heating
during a treatment was expressed as the Cooling Intensity Factor (CIF). The CIF was an index
that represented the rate of heat flux into or out of tissue relative to 37°C. A positive CIF
described the rate of heat flux out of tissue. A negative CIF referred to the rate of heat flux into
tissue. The studies in this section used the CIF as a unit of measure. Current treatment
parameters refer to the temperature at the surface of the applicator.
The ZELTIQ CoolSculpting System has undergone pre-clinical and clinical investigation (data on file at
ZELTIQ). The clinical investigation and results pertaining to skin cooling for fat layer reduction in
submental and submandibular areas, abdomen, flanks, thighs, and alternate treatment parameters are
summarized in this section.
Table 16 summarizes the efficacy information for each study that has been conducted. Further details
on each study can be found in the individual summaries below.

Assessment Time Line
A clinical study that enrolled 60 healthy adult subjects, aged 23 to 65 years at two clinical centers was
conducted from August 2007 through June 2008. Each individual received one or more applications of
the ZELTIQ CoolSculpting System with a ZELTIQ vacuum applicator. Assessments of treatment
