Persistent Organic Pollutants clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

NCT ID: NCT02675101 Completed - Clinical trials for Endocrine Disrupting Chemicals

Nuts and Olestra for Persistent Organic Pollutant Reduction (NO-POPs) Trial

NO-POPs

Start date: March 2016
Phase: N/A
Study type: Interventional

Persistent organic pollutants (POPs) are mostly fat-soluble halogenated chemicals with very long half-lives. POPs are endocrine disruptors, associated with increased risk for diabetes, alterations in thyroid function, and cardiovascular disease in humans. POPs concentrations increase with age because of their persistence, bioaccumulation and poor excretion. The almost ubiquitous presence of endocrine disrupting POPs in US adults is a substantial public health concern, particularly because there is no established treatment to reduce body concentrations of POPs. Most POPs are excreted in bile due to their lipophilic nature. However, a substantial amount is reabsorbed in the small intestine and returns to the blood stream (entero-hepatic circulation). The objective of this pilot study is to conduct a 6-month randomized controlled trial of Nuts and Olestra to enhance the excretion of POPs among 45 healthy adults aged 45 to 70 years with BMIs between 18-30 kg/m2. This study has 3 treatment arms: A) Whole nuts with high fat content (almonds and walnuts; 110g total/day, n=15), B) Olestra: Fat Free PringlesTM potato chips (≈29 crisps, 18g of Olestra/day; n=15), C) Vegetable oil: Original PringlesTM potato chips (≈29 crisps, 17.4g of oil/day; n=15). The investigators aim to measure change in concentrations of 24 POPs in feces after 4 days of treatment and in blood at 6 months.
