Study summary

Pycrinil® is a purified extract of the artichoke leaf. Artichoke leaf extract (ALE) has some clinical trial data suggesting benefit in the treatment of cholesterol disorders in several countries, but this effect has not been studied in a U.S. population. The investigators will give ALE or a placebo to overweight men and women with low "good" cholesterol to see if ALE increases their good cholesterol. The investigators will also make sure that ALE is safe.

Read the detailed description

Subjects will be divided into one of two groups: (1) Pycrinil®/flaxseed oil or (2) Placebo/flaxseed oil twice daily with food. The two formulations will be identical in appearance and standardized by Indena, S.p.A. Patients will be enrolled for a total of 3 months (± 1 week to allow for scheduling flexibility) with a 1 month (± 1 week to allow for scheduling flexibility) first follow-up visit in between enrollment and final visits. At all visits, patients will be asked to monitor for any symptomatic ADE. The first follow-up visit will focus on medication compliance (via pill count) and safety assessment (including laboratories). The final study visit will consist of brief clinical assessment (including anthropometrics), completed lifestyle and physical activity assessments, subjective ADE reporting, and donated blood and urine for clinical laboratory tests. Medication changes are not prohibited during the study period, but must be recorded. Medication bottles will be collected at the first follow-up and final visits; pill counts will be performed to assess compliance.
