This study is designed to determine whether Asians who are especially sensitive to alcohol exposure can be protected by boosting their activities of an alcohol disposing enzyme. This will be accomplished by administering broccoli sprouts that are rich in an agent that increases protective enzyme activity. The test system involves applying alcohol patches to the skin and measuring skin redness.

Condition Intervention Phase
Alcohol Sensitivity
Drug: Broccoli Sprout Extract
Drug: Placebo
Phase 2

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: Double Blind (Participant, Outcomes Assessor)
Primary Purpose: Prevention

Further study details as provided by Johns Hopkins University:

Primary Outcome Measures:
  • Skin Erythema (Skin redness) [ Time Frame: 30 minutes after alcohol skin challenge and every 30 minutes for at least 2 hours. ]
    For three days in a row, volunteers will receive skin treatments with broccoli sprout extract. On day four, their skin will be measured for a baseline skin color reading. Immediately following this reading, the treated areas of the skin will be challenged with 70 percent alcohol and the redness of the skin will again be measured every 30 minutes for the following two hours for skin color changes.

Estimated Enrollment: 10
Study Start Date: April 2014
Estimated Study Completion Date: May 2015
Estimated Primary Completion Date: May 2015 (Final data collection date for primary outcome measure)
