Safety Study of a Disrupted Adenovirus (Ad) Serotype Cocaine Vaccine for Cocaine-dependent Individuals

Phase I Randomized, Double-blind, Placebo Control Study for an Anti-cocaine Vaccine

Sponsor

Weill Medical College of Cornell University

Enrollment

150 participants

Start Date

Jun 26, 2012

Study Type

INTERVENTIONAL

Conditions

Cocaine Dependence

Summary

The purpose of this study is to assess the safety and preliminary efficacy of an anti-cocaine vaccine called dAd5GNE in cocaine-dependent individuals. It uses the concept of a vaccine to treat the neurological effects of cocaine by evoking "immunity" to prevent the effects of cocaine on the brain.

Eligibility

Min Age: 21 YearsMax Age: 69 Years

Inclusion Criteria7

Accrual will be random, with no bias as to gender or racial/ethnic group. Because the accrual process will be random, it is possible that there may be differences in the proportion of males and females, and racial/ethnic groups among the study individuals. All subjects will be concurrently participating in behavioral therapy programs run by Dr. Beeder's clinical team. Each case will be reviewed with the Eligibility Committee, comprised of three investigators other than the PI, to determine eligibility. The Principal Investigator will not participate in this process.
All subjects should be able to provide informed consent.
Must provide HIV informed consent.
Males and females, 21- 69 years of age.
Individuals that have been diagnosed with a cocaine use disorder according to DSM-V-TR criteria, with documented evidence of cocaine use within the past 60 days and have previously used an average of 1 to 10 grams of powdered and/or crack cocaine (via insufflation or smoking only) per week. Any prior 1 to 4 month period of cocaine abstinence in the past year will be excluded when calculating average cocaine use to evaluate study eligibility.
\. Fertile males and females must agree to use adequate forms of contraception for the duration of the entire study.
\. Body weight \> 45 kg.
