Study summary

This is a minimal risk intervention study where healthy volunteers and individuals with Fanconi anemia will consume a single dose of alcohol and provide primarily non-invasive biological samples at various time points. Biospecimens to be collected include saliva, oral cells collected via mouthwash and cheek brush, and urine. The collection of two blood samples (5 mL each) will be optional and banked for future use.

Study arms

  • Experimental
    Group I (alcohol consumption)

    Participants who consume alcohol receive a standard drink or an alcohol dose that will result in a 0.03% BAC PO on study. Participants also undergo collection of saliva and breathalyzer testing throughout the trial.

    Drug: Alcohol · Procedure: Biospecimen Collection · Procedure: Breath Test

  • Active comparator
    Group II (biospecimen collection)

    Participants who do not drink alcohol undergo collection of saliva, mouthwash, and cheek brush samples throughout the trial.

    Procedure: Biospecimen Collection · Procedure: Breath Test

Interventions

  • Alcohol dose given orally that will result in a 0.03% blood alcohol concentration (BAC).

  • ProcedureBiospecimen Collection

    Undergo saliva, mouthwash, and cheek brush collection

  • ProcedureBreath Test

    Undergo breathalyzer testing

What researchers measure

Primary outcomes

  1. Determine the acetaldehyde exposure to the oral cavity by comparing saliva levels before and after alcohol dose

    Identify and quantify DNA adducts in the oral cells (mouthwash and cheek brush samples).

    Time frame: Prior to alcohol dose, and 30 minutes, 1 hour, 2 hours, 4 hours, and 6 hours post alcohol dose

Secondary outcomes

  1. Urine will be analyzed to confirm non-smoking status

    The optional blood samples will be analyzed for DNA adducts in the blood. We will measure the total concentration of the marker NNAL in urine.

    Time frame: Prior to alcohol exposure

  2. Urine will be analyzed to confirm non-smoking status

    The optional blood samples will be analyzed for DNA adducts in the blood. We will measure the total concentration of the marker NNAL in urine.

    Time frame: Up to 6 hours after alcohol exposure
