Filter by:The objective of this study is to determine whether aprepitant blocks the opiate reward system in non-dependent opiate abusers, indicating its potential as a safe, non-addictive first line therapy for early heroin abuse.
Though the HIV epidemic in India is predominantly among heterosexual populations, it is estimated that there are approximately 1.1 million injection drug users (IDUs) in India with HIV prevalence as high as 64% among IDUs in certain cities. In April 2004, the government of India launched a free-antiretroviral therapy roll-out program aimed at initiating 100,000 persons on HAART. Similar guidelines are currently being followed for the delivery and choice of HAART for IDU and non-IDU populations. However, IDUs have certain issues that complicate the delivery of HAART that need to be addressed by delivery programs such as delayed access to care, poor perceived adherence, and more rapid disease progression. This proposal will assess the feasibility and effectiveness of directly administered antiretroviral therapy (DAART) in conjunction with opioid substitution as a mode of delivery of HAART to IDUs in Chennai, India. To evaluate this objective we will conduct a randomized controlled pilot study of DAART vs self-administered therapy (SAT) among 100 HIV-1 infected treatment naïve IDUs who are enrolled in an opioid substitution program in Chennai and compare the following outcomes between the two arms: Primary Endpoint: Proportion of participants with viral load (VL) <400 copies/ml at 24 and 48 weeks; Secondary Endpoints: (1) Incidence of mortality and AIDS-defining illnesses at 24 and 48 weeks, (2) Changes in absolute CD4+ count from baseline at 24 and 48 weeks, and (3) Incidence of antiretroviral drug resistance at 24 and 48 weeks. Intention-to-treat analyses will be used. The study objective is in line with the priority areas identified in the Indian National AIDS Control Program Phase III (NACP III) and the results of this study will help inform the government of India on appropriate modes of delivery of HAART to IDUs. This study will also be among the first studies to be conducted in India to evaluate two different modes of delivery of HAART to IDUs.
This research study takes place at Wayne State University and will take about 11 weeks to complete. This is a treatment research study for individuals who currently have cocaine abuse or dependence, and who may also have heroin dependence. The purpose of this study is to test whether oral sustained release d-amphetamine (SR-AMP) is safe and more effective than placebo for preventing relapse to cocaine use for individuals who abuse or are dependent upon cocaine. We are also interested whether, for patients who are dependent on cocaine and heroin, whether SR-AMP is safe and effective for preventing cocaine relapse in combination with buprenorphine.
The purpose is to study the extent to which stress and other factors, including money, the amount of drug available and the amount of work effort, affect drug choice. This study will assess whether exposure to yohimbine, a drug stressor, increases opioid craving- and -seeking behavior. We will determine whether these behavioral outcomes are associated with biobehavioral stress markers: increased saliva cortisol levels, cardiovascular response (heart rate and blood pressure), and negative mood state.
The study will assess the effectiveness of at-home vs. in-office induction for patients entering buprenorphine maintenance at Associates in Internal Medicine (AIM) primary care clinic.
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.
The purpose is to study how certain factors, including money, the amount of drug available and the amount of work effort, affect opiate drug choice.
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.
This five-year study examines the effectiveness of buprenorphine treatment provided to previously-addicted inmates(N=320; 160 males, 160 females) initiated in prison and continued in the community. The study also examines the extent to which the setting of post-release buprenorphine is provided.It is expected that participants receiving in-prison buprenorphine will have superior outcomes compared to participants who did not receive in-prison buprenorphine.
Prospective participants will undergo a screening process at the clinic to determine eligibility. After screening, eligible patients will complete an 8-day inpatient detoxification, followed by a 12-week outpatient phase. Patients will be randomly assigned to one of two conditions (1) Naltrexone + Placebo; (2) Naltrexone + Memantine 20 mg bid. Long-acting, injectable form of naltrexone (Vivitrol) will be administered once per month (the total of three injections) while memantine or placebo will be taken daily. In addition, patients will receive twice weekly psychosocial intervention that will include motivational interviewing and cognitive-behavioral relapse prevention. The outpatient treatment will also consist of 3 weekly visits to the clinic in which patients will receive counseling to help maintain abstinence and improve compliance with study medication.
