Active clinical trials for "Heroin Dependence"

The study assessed the efficacy of a methadone-induced memory retrieval-extinction procedure on heroin craving and relapse. Male participants aged 18-55 years old and prescribed MMT to treat heroin dependence were included in the present study, and randomly assigned to receive methadone, or receive methadone plus 10 minutes plus extinction, or receive methadone plus 6 hours plus extinction. The intervention persisted 3 times per week for 4 weeks. Then the subjects were followed up once a month for cue induced heroin craving and relapse.

The purpose of this research study is to test the effect of repetitive transcranial magnetic stimulation (rTMS) on opioid cravings among adult patients with Opioid Use Disorder.

This study evaluates the biological markers of treatment of opioid dependent individuals with an extended release formulation of the opioid antagonist naltrexone. The biological measures include functional MRI, blood levels of naltrexone and its metabolites, urine toxicology and behavioral tests probing various aspects of personality, memory, reward processing and attention.

Current treatments for opioid addiction would benefit by the addition of a non-opioid based treatment medication. Recent behavioral studies have shown that the neurokinin-1 (NK1) receptor is involved in opioid reward and withdrawal. This study proposes to study a potential non-opioid treatment, the clinically available, FDA approved, NK1 antagonist aprepitant, in opioid addicted patients. Based on the unique behavioral and pharmacological characteristics of opioid addiction, and what is known of the currently employed treatments, the investigators propose that the therapeutic mechanism of any potential opioid addiction treatment medication must include the ability to reduce opioid withdrawal. This is of particular importance during treatment initiation (eg. detoxification). In addition, for long-term treatment and relapse prevention, it is important to manage drug craving and inhibit the rewarding effects of opioids if patients do experience a slip. Therefore, the investigators propose to study aprepitant using human models of opioid withdrawal, craving and acute opioid reward and reinforcement. The investigators will also include a neuro-economics choice procedure paradigm.

More Americans are arrested for drug offenses than for any other crime. In 2009, over 294,000 arrests were made for possession of cocaine or heroin. Incarceration does not address the root problems and is frequently followed by relapse and re-arrest after release. In the case of opiate-dependent adults arrested for possession of heroin, one potentially effective alternative is to divert offenders to methadone maintenance treatment (MMT) as an alternative to adjudication of their case. MMT is an effective treatment for heroin dependence, and appears very effective for criminal offenders. However, cocaine use is common in MMT patients, including those with recent criminal justice involvement, and MMT alone is ineffective in addressing cocaine use. Continued cocaine use carries a substantial health burden and necessarily entails continued criminal activity. Thus, treatment for diverted opiate-dependent offenders should be designed to address cocaine use as well as opiate use. A Stage 1 Behavior Therapy Development project is planned over 2 years to adapt, manualize and pilot test the Therapeutic Workplace intervention for adults charged with heroin possession and offered diversion to methadone maintenance treatment as an alternative to adjudication of their case. The Therapeutic Workplace is a novel, employment-based contingency management intervention that has been very effective in promoting cocaine abstinence in adults who use cocaine persistently during methadone treatment. In the Therapeutic Workplace, participants are hired in a model workplace and required to provide drug-free urine samples to work and to earn maximum pay. Once we develop and manualize the adapted version of the Therapeutic Workplace for adults arrested for heroin possession, a pilot test will be conducted. Individuals identified by the State Attorney's office as candidates for diversion will be assessed for study eligibility. Given the high rates of injection drug use and injection-related transmission of HIV in Baltimore, this study will be restricted to injection drug users to evaluate the potential utility of this intervention in reducing HIV risk. Eligible individuals will be offered methadone maintenance in lieu of prosecution and will be required to remain in methadone treatment for 90 days. All participants will receive standard MMT, independent of whether they decide to participate in the pilot study. After beginning MMT, participants will be invited to enroll in the pilot study and randomly assigned to two study groups. Participants assigned to the Usual Care Diversion group will receive the standard MMT. Participants assigned to the Therapeutic Workplace Enhanced Diversion group will receive the standard MMT and the Therapeutic Workplace intervention. The data from this pilot study will serve as the foundation for a full-scaled randomized controlled trial. Overall, the Therapeutic Workplace could serve as a novel and ideal intervention for many heroin dependent adults involved in the criminal justice system. The use of MMT in lieu of adjudication in combination with the Therapeutic Workplace could increase drug abstinence and employment and decrease HIV risk and criminal activity in this refractory high-risk population.

In pilot study now proposed, we plan to randomly assign 60 opioid dependent patients to the new model, Depot-BNT, or to BNT plus oral naltrexone for a 6-month trial. This will provide initial clinical experience with the new Depot-BNT treatment model, while providing a rigorous test of whether Depot-BNT produces superior treatment outcome, compared to our best behavioral platform for oral naltrexone (BNT). The following aims will be addressed: Specific Aim #1: To test whether Depot-BNT increases retention in treatment and improves drug use outcome (urine-confirmed abstinent weeks) compared to our established model of BNT with oral naltrexone (BNT-Oral), and to explore whether Depot-BNT (vs BNT-Oral) improves key secondary outcomes including dysphoria, HIV risk behavior, and social functioning. Specific Aim #2: To explore predictors of outcome on Depot-BNT, and mechanisms of attrition, in order to optimize Depot-BNT prior to further testing.

Stress is one of the more common reasons cited by addicts for continual drug use and relapse. Treatment approaches that target both drug-induced and stress-induced relapse may prove to be more beneficial than targeting drug-induced relapse alone. Lofexidine is a drug that reduces the physical symptoms of opiate withdrawal and may prove to have stress-reducing capabilites in drug addicts. The purpose of this study is to determine the maximal safe dose of lofexidine tolerated in naltrexone-treated heroin addicts and to find an optimal lofexidine induction schedule.

The purpose of this study is to assess the safety and effectiveness of buprenorphine for treatment of concurrent intravenous heroin and cocaine dependence.

The purpose of this study, SALOME, is to determine if 1) the closely supervised provision of injectable, hydromorphone (HDM; trade name Dilaudid™) is as effective as injectable diacetylmorphine (DAM; heroin) in the treatment of chronic, multi-morbid opioid-dependent individuals who have not benefited sufficiently from conventional treatments, and if a switch to the oral equivalent of hydromorphone and diacetylmorphine is as effective as the injection form. The availability of an effective, licensed opioid medication such as hydromorphone, for substitution treatment of chronic, multi-morbid treatment-refractory opioid-dependent individuals, would be of immense impact locally and internationally. It could help to establish alternative treatment options where for non-medical reasons Heroin Assisted Treatment would not be acceptable. Thus, one result could be the expansion of treatment options for the most difficult to treat heroin dependent persons. This would also be an important step for secondary prevention of HIV and Hepatitis C as well as a better integration of those patients in other medical treatments. Switching from intravenous to oral application would also reduce a lot of potential risk factors (like overdose, seizures, infections, etc) and side effects associated with the injection route. Additionally it could make these treatments more feasible in normal treatment settings, like existing methadone services.

The purpose of this study is to see whether street-recruited heroin users can be successfully treated for hepatitis C after stabilizing them on buprenorphine.
