Cocaine vaccine enters human testing
NCT ID NCT02455479
First seen Jun 25, 2026 · Last updated Aug 27, 2026 · Updated 3 times
Summary
This study tests a vaccine called dAd5GNE in 150 people who are dependent on cocaine. The vaccine is designed to train the immune system to attack cocaine, preventing it from reaching the brain and causing a high. The main goal is to check if the vaccine is safe, while also measuring whether it reduces cocaine use.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- dAd5GNE vaccine
- What this could lead to
- If it works, this vaccine could help people with cocaine dependence by reducing cravings and preventing relapse.
- What could go wrong
- This is a very early phase 1 trial focused on safety, so it may not prove effective. The vaccine may not produce strong enough immunity to block cocaine's effects.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
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 must fulfill all inclusion criteria and none of the exclusion criteria in order to participate in this study. Inclusion Criteria: 1. All subjects should be able to provide informed consent. 2. Must provide HIV informed consent. 3. Males and females, 21- 69 years of age. 4. 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. 6\. Fertile males and females must agree to use adequate forms of contraception for the duration of the entire study. 7\. Body weight \> 45 kg. Exclusion Criteria: 1. Individuals not deemed in good overall health by the investigator. 2. Diagnosed history of severe psychotic disorders. 3. Abnormal EKG at screening with changes consistent with cardiac disease. 4. History of significant cardiovascular disease, hypertension, prior myocardial infarction and/or cerebrovascular event. 5. Individuals who are currently on beta-blockers. 6. Physical signs or laboratory values suggestive of systemic disorders. 7. History of attempted suicide, as assessed by Columbia-Suicide Severity Rating Scale (C-SSRS) and/or committed homicide. 8. History of diagnosed obsessive compulsive disorder (OCD). 9. Known allergy to soy. 10. Individuals who are currently taking alprazolam (Xanax) or ziprasidone (Geodon). 11. Evidence of active infection of any types, including COVID-19, or positive for human immunodeficiency virus (HIV). 12. Historical or current use of immunomodulators or immunosuppressants \<5 years prior to screening. 13. Receipt of blood within 3 months of screening. 14. Females who are pregnant or nursing. 15. Concurrent participation in any other FDA approved Investigational New Drug. 16. Abnormal liver function (transaminases greater than 2x the upper limit of normal values) 17. eGFR \<30 mL/min/1.73 m2 18. Severe substance use disorder based on DSM-V-TR criteria (excluding cocaine, nicotine, caffeine, alcohol, marijuana and opiates prescribed for medication assisted therapy or pain treatment) currently not in remission according to one of the following criteria: * 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 * Sustained Full Remission: This specifier is used if none of the criteria for Dependence or Abuse have been met at any time during a period of 12 months or longer OR * Sustained 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 a period of 12 months or longer OR * On Agonist Therapy: This specifier is used if the individual is on a prescribed agonist medication, and none of the criteria for Dependence or Abuse has been met for that class of medication for at least the past month (except tolerance to, or withdrawal from, the agonist). 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). 19. History of any seizure disorder. 20. Individuals with history of Guillain-Barré Syndrome. 21. Diagnosis of \>2 Substance Use Related Disorders (mild) based on DSM-V- TR criteria (excluding nicotine, caffeine, alcohol, marijuana and opiates prescribed for medication assisted therapy or pain treatment 22.
