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

Description

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.

  • * Early Full Remission: This specifier is used if none of the criteria for Dependence or Abuse have been met for at least 1 month, but less than 12 months OR
  • * Early Partial Remission: This specifier is used if only one or more (but not all) of the criteria for Dependence or Abuse has/have been met for at least 1 month, but less than 12 months. OR

This category also applies to those being treated for Dependence using a partial agonist or an agonist/antagonist OR
  • * Substance Use Related Disorder (mild) up to two disorders: Patients that are assessed to have mild substance-use-related disorders according to the DSM-V criteria will be allowed to participate in the study as long as the number of the disorder-resulting substances does not exceed two (with the exception of the nicotine, caffeine, alcohol, marijuana and opiates prescribed for medication assisted therapy or pain treatment).
