The purpose of this study is to determine whether low level laser light therapy is effective in reducing circumference of the waist, hips and upper abdomen in obese individuals.
The American Society of Plastic Surgeons (ASPS) 2011 report states that the market for cosmetic procedures has shown significant growth over the past two years, with 13.8 million cosmetic plastic surgery procedures performed in the United States in 2011, up 5% since 2010. While surgical cosmetic procedures did increase significantly from 2010 to 2011, the overall growth in cosmetic procedures is being primarily driven by a substantial rise in minimally-invasive procedures. Cosmetic minimally-invasive procedures increased 6%, with nearly 12.2 million cosmetic minimally-invasive procedures having been performed in 2011. This highlights the growing consumer demand for non- or minimally-invasive cosmetic procedures that do not involve surgical procedures such as liposuction and the associated risks, potential complications and lengthy and painful recovery processes.
Low level laser light therapy, such as that to be provided through application of the Erchonia® Obesity Laser in this clinical study protocol, offers a simple, non-invasive, safe, effective and side-effect free alternative to achieving body circumference reduction.
Justification for this assertion of anticipated safety and effectiveness of the application of the Erchonia® Obesity Laser for the reduction of body circumference is found through three FDA clearances for Erchonia® Low Level Laser devices for body circumference reduction indications, as follows:
K123237 (532 nm green light diodes): Erchonia® Zerona™ 2.0 Laser: is indicated for use as a non-invasive dermatological aesthetic treatment as an adjunct for individuals intending to undergo liposuction procedures for the reduction of circumference of hips, waist, and thighs.
K121695 & K082609 (635 nm red light diodes): Erchonia® ML Scanner (MLS) & Erchonia® Zerona: is indicated for use as a non-invasive dermatological aesthetic treatment as an adjunct for individuals intending to undergo liposuction procedures for the reduction of circumference of hips, waist, and thighs.
K121690 & K120257 (635 nm red light diodes): Erchonia® MLS, Zerona, Zerona-AD: is indicated for use as a non-invasive dermatological aesthetic treatment as an adjunct for individuals intending to undergo liposuction procedures for the reduction of circumference of the upper arms.
Therefore, Erchonia low level lasers have been determined safe and effective by the FDA for application for body circumference reduction indications for multiple body areas, such that evaluation of application of the Erchonia Obesity Laser to reducing body circumference in more overweight individuals is a natural extension of its proven and accepted application for body circumference reduction purposes.

| Difference in the Proportion of Primary Outcome Successes Between Treatment Groups for Change in Combined Circumference Measurements | Individual measurements in inches of the waist, hips and upper abdomen were combined to calculate a total body circumference measurement. Change in combined circumference measurement from baseline to 4 weeks was calculated for each subject. Individual subject success was defined as a change of 3.0 inches or more in the combined circumference measurement across the evaluation period. A decrease in combined circumference measurement is positive for individual subject success. An increase in combined circumference measurement is negative for individual subject success. Overall study success was defined as a 40% or greater difference between the proportion of individual successes in each treatment group. | Baseline and 4 Weeks |
| Change in Combined Circumference Measurement | Individual measurements in inches of the waist, hips and upper abdomen were combined to calculate a total combined body circumference measurement. Change in combined circumference measurement is calculated as the difference in circumference measurements from baseline to endpoint (4 weeks). A negative (-) change indicates a decrease in circumference and is positive for study success. A positive (+) change indicates an increase in circumference and is negative for study success. | Baseline and 4 Weeks |

| Subject Satisfaction With Procedure Outcome | Subjects rated satisfaction with the outcome of the study procedures with respect to change in body shape on the following 5-point scale: Very Satisfied, Somewhat Satisfied, Neither Satisfied nor Dissatisfied, Not Very Satisfied, Not at All Satisfied. Results are reported as the number of subjects in each treatment group who rated study outcome satisfaction as 'Very Satisfied' or 'Somewhat Satisfied'. |
