Filter by:The purpose of the study is to conduct a follow-up of substance abuse patients (n=1,269) about 2 to 5 years since they were originally recruited from 8 substance abuse treatment clinics (located in 5 states) to participate in a prior clinical trial study called "START" (Starting Treatment with Agonist Replacement Therapies). The START Follow-up Study will be conducted over 5 years and will involve three follow-up interviews with START participants. The specific aims of the START Follow-up Study are as follows. 1. To determine longer-term outcomes of Suboxone versus methadone treatment received in the START 2. To investigate patient and treatment factors associated with post-START treatment access, utilization, and outcomes among Suboxone and methadone patients 3. To explore other correlates of the long-term outcomes among START patients.
This study is designed to determine if opioid dependent subjects who are already receiving Subutex and/or Suboxone can transfer to RBP-6300. Upon completing the study, subjects will continue their pre-study prescribed dosage of Subutex and/or Suboxone
The main objective is to compare the genotypes of the COMT Val158Met polymorphism between opiate-users and opiate-dependent subjects. The secondary objective is to constitute a sample of opiate-users without any lifetime opiate dependence.
In this 5-year study, the investigators propose to evaluate the separate and combined effects of the FDA-approved formulation of extended release naltrexone (Vivitrol®) and employment-based reinforcement of opiate abstinence in promoting opiate abstinence and reducing risky injection behavior in recently detoxified, opioid-dependent, injection drug users.
The aims of STRIDE were changed as of July, 2014. The revised project, called STRIDE2, has a longitudinal, non-randomized, observational study design. The population under study consists of individuals living with HIV who are dependent on opioids.
This research deals with behaviors that are part of opioid dependence. The purpose is to study the extent to which stress and other factors, including money and amount of work effort, affect opioid choice. Specifically, the investigators will examine the effects of three issues/factors. The first is how hard participants are willing to work to obtain an opioid drug; the second is how much opioid drug would participants choose instead of money; and the third factor is how much participant's opioid drug choices are influenced after they are administered the drugs yohimbine and hydrocortisone, both of which could produce stress-like symptoms.
This is an open-label (both the physician and healthy volunteer know which medication will be administered), single-dose, 5-dosing period study to characterize the pharmacokinetics (process by which oxycodone is absorbed, distributed, metabolized, and eliminated by the body) and the effects of food on the pharmacokinetics of oxycodone. The study will take place over approximately two and a half months and will consist of three phases: a screening visit to determine eligibility for the study, a 5-dosing period treatment phase, and an end-of-study visit.
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.
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
This phase 4 study will evaluate the feasibility of initiating subjects on VIVITROL in prison and continuing VIVITROL upon release into the community.
