Active clinical trials for "Opioid-Related Disorders"

The purpose of this study is to determine if two times a subject's daily maintenance dose will hold for 48 hours without changes in agonist and antagonist effects.

The purpose of this study is to determine if six times daily buprenorphine dose is effective in achieving 120 hour buprenorphine dosing.

The purpose of this study is to examine the interactions between buprenorphine and naltrexone, and to assess how they may directly impact the clinical issues involving: transferring patients from buprenorphine to naltrexone, developing a non-abusable form of buprenorphine, and enhancing patient acceptability of naltrexone.

The purpose of this study is to conduct experiments to examine subjective and reinforcing effects of nitrous oxide. Mood altering and psychomotor effects will be tested on non-drug abusers and preference procedures will be used to assess reinforcing effects. To examine effects of subanesthetic concentrations of nitrous oxide on cold-pressor pain in humans.

The purpose of this study is to conduct experiments to examine subjective and reinforcing effects of nitrous oxide. Mood altering and psychomotor effects will be tested on non-drug abusers and preference procedures will be used to assess reinforcing effects. To evaluate the acute and residual effects of subanesthetic concentrations of isoflurane/nitrous oxide combinations in healthy volunteers.

The purpose of this study is to evaluate the effects of treatment medications (methadone, buprenorphine, LAAM, naltrexone, naltrexone microcapsules, and methoclocinnamox) on I.V. and smoked heroin self-administration."

This pilot study will examine the safety of the cannabinoid cannabidiol (Epidiolex) in a human laboratory model of clinically relevant withdrawal. The study will be a residential within-subject comparison; all participants will receive placebo dosing and active cannabidiol. Results may be used to support an R01 grant application to more closely examine this hypothesis.

The purpose of this study is to address two key questions in the literature on incentives for substance use. The first question is whether it is more effective to directly incentivize the outcome of interest - drug abstinence - or to incentivize behaviors that are inputs into the production of abstinence. This study will compare two versions of the incentive program: one that incentivizes inputs to achieving abstinence and one that incentivizes the outcome of abstinence. The second question is how to optimize the size of incentives over time to maximize incentive effectiveness. This will be done by randomly varying the size and timing of incentives offered to participants in both the Inputs and Outcomes groups. The incentive amounts will then be varied across participants and time to fit a structural model of abstinence behaviors over time. The model will be used to describe the optimal shape of incentives over time.

The proposed research will evaluate the ability of a mobile, rapid induction procedure to engage individuals in ongoing medication assisted treatment. A total of 250 untreated individuals meeting criteria for opioid use disorder and at high risk of opioid overdose will be enrolled in the study. Recruitment will take place in two targeted neighborhoods of Philadelphia (Kensington and South Philadelphia) with a high prevalence of fatal and non-fatal opioid overdose. A total of 250 participants will be engaged in the research. Following informed consent and determination of eligibility, 125 individuals will be enrolled as they engage with the mobile, rapid induction team and 125 individuals will be enrolled as they seek treatment from the CRC Episcopal Hospital (serving Kensington area) or BAC/CRC Hall Mercer Community Mental Health (serving South Philadelphia). The intervention group will receive four weeks of treatment with buprenorphine /naloxone and support for treatment engagement provided by a case manager and a peer recovery specialist. All participants will be assessed at baseline and then 1- and 6-month following enrollment. The primary endpoint for the study is continued enrollment in medication-assisted treatment at 6-month post-enrollment. The proposed research will evaluate the ability of a mobile, rapid induction procedure to engage individuals in ongoing medication assisted treatment. The specific aims are: Aim 1: To evaluate the impact of the mobile, transitional MAT intervention on its ability to engage participants in targeted, existing MAT treatment slots at 1- and 6-month post-enrollment. Aim 2: To evaluate the impact of the mobile intervention on subsequent drug use and overdoses at 6-month post-enrollment. Aim 3: To assess the acceptability and costs of the intervention. The program and patient costs of delivering and participating in the intervention will be documented.

This study is to evaluate the safety and tolerability of initiating SUBLOCADE™ treatment following a shorter period of transmucosal (TM) buprenorphine treatment.
