Polybrominated Biphenyl Poisoning Clinical Trial
Official title:
Use of a Weight Loss Aid in a Population Exposed to Polybrominated Biphenyls (PBB)
This study will explore whether the use of orlistat results in weight loss that is accompanied by a reduction in the body burdens of polybrominated biphenyls (PBB) and other Persistent Organic Pollutants (POPs).
Millions of people living in Michigan were exposed to brominated flame retardants (polybrominated biphenyls or PBB) as a result of the largest agricultural disaster in US history. Over the past six years, Emory researchers have tested nearly 900 Michigan residents and determined that 60% still had PBB in their bodies from that disaster. PBB is stored in body fat and the researchers at Emory have been asked by community members if weight loss might reduce their body burdens of PBB and other lipophilic chemicals. In an effort to understand how PBB and other persistent organic pollutants (POPs) are eliminated, the researchers are conducting a randomized trial of orlistat versus placebo. Orlistat is an over-the-counter product approved by the FDA for weight loss and works by increasing excretion of fat into the stool. Since PBB is stored in body fat, the researchers hypothesize that orlistat may reduce the body burden of PBB and other POPs. This study is a randomized, placebo-controlled trial of orlistat (at the dose available over-the-counter) plus diet and exercise for 6 months in a population with elevated PBB levels. Participants will be healthy overweight adults and orlistat will be taken as directed for the approved indication (weight loss). ;
