Low Level Laser Treatment (LLLT) and Lorcaserin for Weight Management

Completed · Phase 3

Conditions studied: Overweight, Obese

In brief

Currently in the United States about 97 million adults are considered obese, accounting for about 33% of the American adult population (compared to 22.9% in 1988). Obesity, defined as a body mass index of 30.0 or higher, is accountable for 44% of the diabetes, 23% of the ischemic heart disease and between 7% and 41% of certain cancers. The Erchonia® Zerona™ 2.0 Laser (which will be used in this study) has been approved by the FDA (K123237) as a non-invasive dermatological aesthetic treatment which can be used by individuals intending to reduce circumference of hips, waist, and thighs. Lorcaserin is a selective serotonin 2C (5-HT(2C)) receptor agonist. The exact mechanism of action is not known, but lorcaserin is believed to promote satiety and decrease food intake by activating 5-HT(2C) receptors on anorexigenic pro-opiomelanocortin neurons in the hypothalamus. Lorcaserin was approved by the FDA on June 2012 for weight management in people with a BMI of \> 27 kg/m2 (overweight) when accompanied by a weigh-related condition such as type 2 diabetes or high blood pressure or in people with a BMI \> 30 kg/m2 (obese). The purpose of this pilot study is to obtain preliminary data on: 1) effectiveness of the combination of LLLT and lorcaserin for reducing abdominal subcutaneous fat in overweight/obese individuals; 2) impact of LLLT on inflammatory biomarkers, blood sugar, and cholesterol.

You may not qualify if…

• have used weight loss medications or participated in a weight loss program within the past 30 days;
• are currently taking supplements known to affect weight, such as garcinia cambrogia.
• have had weight fluctuations of 20 pounds or more in the past 6 months (self-report);
• have an implanted device (including pacemaker or lap band) in the targeted area of LLLT;
• have an active untreated clinically significant psychiatric condition (psychosis, bipolar disorder, or depression);
• have used an investigational drug within 30 days of study enrollment;
• have a recent history (past 30 days) of alcohol or drug abuse or dependence;
• are currently pregnant or lactating, or are of child-bearing potential or are likely to become pregnant during the medication phase and are unwilling to use a reliable form of contraception;
• have a history of any major cardiovascular events including heart valve disease, cardiac arrhythmias, congestive heart failure, acute coronary syndrome, stroke, transient ischemic attack, or peripheral vascular disease;
• have current uncontrolled hypertension (systolic > 165 mm Hg or diastolic > 95 mm Hg) documented on 2 separate occasions;
• have clinically significant acute or chronic progressive or unstable neurologic, hepatic, renal, cardiovascular, lymphatic, respiratory, or metabolic disease (such as diabetes) or active cancer or are within 1 year of cancer remission;
• Prior surgical intervention for body sculpting/weight loss, such as liposuction, abdominoplasty, stomach stapling, lap band surgery, etc.;
• medical, physical, or other contraindications for body sculpting/weight loss;
• current use of medication(s) known to affect weight levels/cause bloating or swelling and for which abstinence during the course of study participation is not safe or medically prudent;
• concurrently taking a serotonergic drug (selective serotonin reuptake inhibitors (SSRIs), serotonin-norepinephrine reuptake inhibitors (SNRIs), monoamine oxidase inhibitors (MAOIs), triptans, bupropion, dextromethorphan, St. John's Wort). These drugs can be used to treat depression and/or migraines but are contraindicated with lorcaserin;
