NCT01999946
The purpose of this study is to compare the effectiveness of extended-release naltrexone (XR-NTX) vs. enhanced treatment-as-usual (TAU) among opioid dependent adults leaving NYC jails. In parallel, we propose to recruit a matched, quasi-experimental methadone cohort, which will result in a naturalistic comparison of XR-NTX vs. an established jail-based methadone treatment program standard-of-care. Our primary aim is to compare time-to-relapse among participants treated with XR-NTX vs. randomized TAU controls and time-to-relapse among XR-NTX arm vs. jail-based MTP participants, following release from jail. Secondary aims will compare related opioid treatment outcomes post-release across all arms.
NCT03922659
Heroin dependence is one of most common substance dependence, which brings great burden on health worldwide. Heroin dependence may lead to immunosuppression and cognitive impairments. Once heroin dependence is developed, it will be difficult to recover and easy to relapse. Although many efforts had been made in the treatment of heroin dependence, the annual recurrence of heroin dependence with traditional therapies would be up to 90%. Repetitive transcranial magnetic stimulation (rTMS) on the dorsolateral prefrontal cortex (DLPFC) or cognitive behavioral therapy (CBT) each alone was reported to have some effect on preventing from relapse of substance dependence. In order to test whether combined therapy of high frequency rTMS (hf-rTMS) with CBT is better for preventing from relapse of heroin dependence, we recruit patients with heroin dependence to participate this study. The study is a factorial designed and the patients will be assigned into one of the following six groups randomly: (1) regular treatment (symptomatic treatment) with blank TMS; (2) regular treatment (RT) with blank TMS and CBT; (3) RT with right DLPFC hf-rTMS; (4) RT with right DLPFC hf-rTMS and CBT; (5) RT with left DLPFC hf-rTMS; (6) RT with left DLPFC hf-rTMS and CBT. TMS was given 5 days per week for total 2 weeks using uniform scheme (5 seconds of 10Hz stimulation per train, 30 trains per day with inter-train interval of 20 seconds). CBT will be given once per week for total 8 weeks. The patients will be followed up for 6 months. Recurrence of heroin dependence, duration of abstention, heroin/drug intake, craving for heroin and other cognitive psychological assessments will be recorded and compared among the 6 treatment groups and the efficacy of combined therapy of rTMS with CBT will be evaluated in our study.
NCT00249470
The primary purpose of the study is to determine if the central feature of the Therapeutic Workplace, the abstinence reinforcement contingency, is critical to initiate cocaine abstinence in injection drug using methadone patients who use cocaine consistently during methadone treatment. All subjects initially will be invited to attend the Therapeutic Workplace for an initial period, but abstinence will not be required to work during that time. During this initial period, vouchers will be contingent only on workplace attendance and performance on the training programs. Subjects (n=70) who attend the workplace consistently during the first 4 weeks of treatment, but who continue to use cocaine will be randomly assigned to a Work Only or an Abstinence Plus Work group. Subjects in the Work Only group will continue to be able to work independent of their urinalysis results. However, subjects in the Abstinence Plus Work group will be required to provide urine samples that show evidence of recent cocaine abstinence. Subjects in both groups will be invited to stay in the workplace for 6 months. We expect the subjects in the Abstinence and Work group will achieve higher rates of abstinence than the subjects in the Work Only group. This result would show that the abstinence reinforcement contingency (i.e., the requirement to provide cocaine-free urine samples to work and earn vouchers) is important in the initiation of abstinence in the study population.
NCT00149669
A randomized study is planned over 5 years to evaluate the effectiveness of the Therapeutic Workplace in promoting naltrexone ingestion and abstinence in unemployed opiate-dependent injection drug users. Participants will be offered an opioid detoxification and naltrexone induction. Participants who complete the naltrexone induction will be randomly assigned to one of two groups. Both groups will be invited to work in the Therapeutic Workplace and prescribed naltrexone for 26 weeks. The groups will differ in the contingencies imposed to work and earn salary. Work Plus Naltrexone Contingency participants will be required to ingest naltrexone to work, and will receive a brief pay decrease for missing a dose. Work Plus Naltrexone Prescription participants will be prescribed naltrexone, but will not be required to ingest it to work. This study will provide a rigorous evaluation of a novel employment-based intervention, the Therapeutic Workplace, to promote naltrexone ingestion and drug abstinence in a population of injection drug users who are at considerable risk of spreading or contracting HIV infection. Hypotheses being tested in this study are: Naltrexone ingestion will be maintained in the group exposed to the employment-based naltrexone treatment significantly more than the group exposed to usual-care treatment package. Opiate abstinence will be maintained in the group exposed to the employment-based naltrexone treatment significantly more than the group exposed to usual-care treatment package.
NCT00577408
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.
NCT00000330
The purpose of this study is to assess the abuse liability and reinforcing effects of intravenous buprenorphine and buprenorphine/naloxone combinations in heroin-dependent volunteers
NCT00000326
The purpose of this study is to assess the clinical efficacy of the buprenorphine/naloxone combination tablet for alternate-day dosing and determine whether multiples of the daily dose are necessary to maintain an effective alternate day dosing regimen.
NCT00000327
The purpose of this study is to compare the clinical efficacy of daily vs. 3-day (MWF) buprenorphine/naloxone combination tablet administration and determine whether outcomes are improved when using a 3-day schedule in which all doses are ingested at the clinic vs. one in which take-home doses are given on intervening days.
NCT00000329
The purpose of this study is to assess the abuse liability and examine the reinforcing effects of intravenous buprenorphine and buprenorphine/naloxone combinations in buprenorphine-naloxone maintained volunteers
NCT03071315
The study compared the effectiveness and cost-effectiveness of two dominant heroin dependence treatment approaches: center-based compulsory rehabilitation (CCT) and community-based voluntary methadone treatment (MMT) in Hai Phong City, Vietnam. The design was a combined retrospective and prospective, non-randomized cohort over three years (with data at five time-points). The study was conducted between 2012 and 2015, involving 208 CCT participants and 384 MMT participants with heroin dependence.
NCT00326235
Dependence on heroin is a major public health problem because of its association with criminality, law enforcement costs and healthcare costs. Managed withdrawal is a required first step for a long term drug-free treatment of heroin addicts. Methadone and clonidine have been the mainstay of treatment for the relief of heroin withdrawal symptoms but both have limitations. The purpose of this study was to evaluate the efficacy of buspirone in the alleviation of the withdrawal symptoms experienced by heroin addicts when they stop using heroin. Buspirone is a non opiate drug with no abuse potential, no sedating effects and no withdrawal symptoms.
NCT00000211
The purpose of this study is to assess the safety and effectiveness of buprenorphine for treatment of concurrent intravenous heroin and cocaine dependence.
NCT00158288
Although LAAM, a derivative of methadone, has been successfully used as an alternative to methadone maintenance in opioid addicts, its effect on concurrent opioid and cocaine abuse has not been ascertained. Thus, this study proposes to examine the clinical efficacy of low- and high-dose LAAM maintenance on opioid and cocaine use in opioid-dependent cocaine abusers. In addition, since contingency management procedures have demonstrated some success in decreasing cocaine use in cocaine-abusing individuals, this study also proposes to examine the clinical efficacy of the presence or absence of contingency management procedures targeting illicit drug use.
NCT01447212
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.
NCT01471145
The aim of this project is to study brain functions of 20 heroin addicts (compared to brain functions of 20 healthy controls) just before and during a three month extended release naltrexone treatment using functional MRI and dopamine transporter SPECT. The following hypotheses are tested: * XRNT modulates the fMRI response to drug cues in predetermined brain regions. * The expression of striatal transporters (assessed with SPECT) will decrease after a three-month course of extended release naltrexone
NCT00609089
The planned research will adapt an intervention of known efficacy to target a new outcome of significant importance to public health. Specifically the Community Reinforcement and Family Training (CRAFT) procedures will be adapted, from reinforcing treatment entry, to reinforcing treatment retention and HIV risk behavior reduction in persons with opioid dependence who receive a Buprenorphine taper detoxification. The research plan includes three phases: 1) development of a manual guided therapy, 2) development of therapist training and fidelity measures and 3) a randomized pilot evaluation with 52 patients receiving either the new CRAFT treatment or treatment as usual.
NCT00429767
The purpose of this study is to determine whether maintenance on different oral doses of sustained release d-amphetamine (SR-AMP) combined with constant-dose sublingual buprenorphine (BUP) is safe and well tolerated and decreases self-administration of cocaine alone or combined with hydromorphone (HYD). Secondary aims are to determine whether SR-AMP attenuates the subjective and physiological effects of cocaine during drug sampling periods prior to choice opportunities.
NCT00310934
The objective of this study is to compare optimally given methadone maintenance treatment (MMT) for heroin dependence with a novel, sequential strategy, where patients are offered buprenorphine as first line treatment, allowed dose adjustments as needed, and switched to methadone if the maximal dose of buprenorphine is insufficient.
