Avmacol is an over-the-counter dietary supplement containing broccoli seed and sprout extracts in tablet form, hypothesized to activate protective cellular pathways including detoxication. In this study, healthy volunteers will take 3 days of Avmacol in order to evaluate both bioavailability and its bioactivity in cheek cells.
Dietary Supplement: Avmacol
||Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Prevention
||A Pilot Study Evaluating the Bioavailability and Mucosal Bioactivity of the Dietary Supplement, Avmacol®, in Healthy Volunteers With Optimization of Buccal Cell Biomarkers

| Estimated Primary Completion Date:
||June 2017 (Final data collection date for primary outcome measure)
Experimental: Avmacol during week 2 for 3 days
Buccal cells line the inner cheek, and will be collected from the inner right cheek with a cytobrush (a q-tip like swab) by a trained investigator.
During the second week the participant will take 8 Avmacol tablets every evening for 3 evenings (Day 2, 3, 4), and record the time of each dose in the provided diary. Research blood collection: on days 1 and 5. Overnight urine collection.
Dietary Supplement: Avmacol
Avmacol is an over-the-counter mixture of broccoli seed and sprout extracts in tablet form to promote detoxification. These tablets contain natural substances that stimulate the body's own defense mechanisms against toxic substances commonly encountered in the environment, such as air pollution and tobacco smoke.
- Sulforaphane Production System
- broccoli seed and sprout extract
Avmacol is an over-the counter dietary supplement containing broccoli seed and sprout extracts in tablet form. Natural plant substances within Avmacol, called phytochemicals, are hypothesized to stimulate the body's own defense mechanisms against toxic substances commonly encountered in the environment, such as air pollution and tobacco smoke. The purpose of this study is twofold: 1) to assess the protective effects of Avmacol on the mucosa (cheek cells) of healthy volunteers, and 2) to assess the collection of cheek cells by scraping, as a less invasive method of studying drug effects in the body compared to drawing blood or a tissue biopsy. Ultimately, these results will be used to design a larger study of Avmacol in patients with tobacco-related head and neck cancer. Avmacol will be studied as a way to possibly prevent a second cancer from developing in these patients.
