Active clinical trials for "Opioid-Related Disorders"

This study will compare the effects of brief strengths-based case management (SBCM) to the effects of screening, assessment and referral alone (SAR) in opioid-dependent patients. Participants meeting DSM-IV criteria for opioid dependence will be randomly assigned (150 per group) to receive 1) up to 6 sessions of SBCM; or 2) SAR. Follow-up assessments will be completed at 3 and 6 months, by staff who are blinded to treatment condition.

A multi-center, open-label, long-term safety study in which approximately 600 subjects diagnosed with opioid use disorder will be enrolled. Following a screening period, all subjects will receive run in SUBOXONE sublingual film followed by an initial injection of open-label high dose (300 mg) RBP-6000. The RBP-6000 monthly injection dose can be adjusted to low dose (100 mg), and back to high dose, based on the medical judgment of the Investigator. Subjects will participate in the study for either 6 or 12 months.

Open-label multi-center, 48 week safety study, consistent with standard practice for long-term safety studies. This one year safety study will utilize CAM2038 q1w (once weekly) and q4w (once monthly) and will have 3 phases: Screening, Treatment, and Follow-up.

Using combination of opioid analgesics and analgesics with different mechanism of action the investigators can decrease the consumption of opioid analgesics and their side effects. The investigators will use opioid analgesic fentanyl alone or in combination with dexmedetomidine or lidocaine.The participants scheduled for laparoscopic intestine resection will be divided in three groups: in the first group, the participants will receive single boluses of fentanyl, in the second group, the participants will receive continuous infusion of lidocaine and single boluses of fentanyl, and in the third group, the participants will receive continuous infusion of dexmedetomidine and single boluses of fentanyl. Participants with intraoperative infusion od dexmedetomidine or lidocaine will need less boluses of fentanyl during the operation and less opioid analgesics after the operation in comparison to those who will receive only fentanyl boluses. Better cognitive function after the operation is expected in participants receiving dexmedetomidine infusion. There will be minimal incidence of neuropathic pain because of minimal surgical injury of peripheral nerves in all groups of patients.

The goal of the MySafeRx study is to evaluate the feasibility, acceptability, and usability of a novel platform that integrates text messaging reminders, secure electronic pill organizers, and daily remote brief motivational recovery support visits with a standardized protocol for supervised self- administration of buprenorphine via videoconferencing.

The primary objective of this study is to assess lofexidine related effects on QTc (an interval of the heart rhythm) in subjects receiving buprenorphine maintenance. The secondary objectives of the study are to evaluate the safety and tolerability of lofexidine by evaluating and monitoring pharmacokinetics (amounts of drug in the blood), vital signs (heart rate and blood pressure) and adverse events (side effects) when co-administered with buprenorphine; to describe effects on opiate withdrawal when lofexidine is introduced following a 50% buprenorphine dose reduction, as required to elicit a withdrawal response; and to evaluate QTc interaction effects of lofexidine compared with placebo. The Investigators hypothesize that while lofexidine is known to prolong the QTc interval, the combination of the drugs will not create an additive effect which creates a significant safety concern. The Investigators further hypothesize that subjects will be able to tolerate the therapeutic dose of lofexidine (0.8 mg four times daily) when the buprenorphine maintenance dose is lowered to elicit withdrawal.

The purpose of this study is to pilot and evaluate, in a randomized controlled trial, the immediate and long-term effects of a newly developed, tailored, intensive smoking cessation intervention among methadone maintained smokers and compared to a control condition (facilitated referral to the NJ Quitline). The newly developed intervention is evidence based, addresses the unique needs of methadone maintained smokers, is intensive, can be tailored to the individual, and builds on the strengths as well as addresses the gaps in previous treatments for methadone maintained smokers. The investigators hypothesize that: (1) three months and six months after beginning treatment, those in the tailored intervention condition will be more likely to be abstinent from smoking than those in the control intervention condition (primary outcome); (2) there will be a greater relapse rate in the control intervention condition between the three and six month follow-up points than in the tailored intervention condition; (3) three and six months after beginning treatment, those in the tailored intervention condition will have better secondary smoking related outcomes (smoked fewer cigarettes per day in the past week, be more ready to quit, have greater self-efficacy for quitting, experience less nicotine dependence, and be more likely to have made a quit attempt) than those in the control intervention condition; (4) three and six months after beginning treatment, those in the tailored intervention condition will have better utilization of and adherence to smoking cessation pharmacotherapy, better mental and physical health, less perceived stress, greater social support, less drug and alcohol use, and greater involvement in drug and alcohol treatment than those in the control intervention condition; and (5) the newly created tailored intervention will be feasible and acceptable. .

The long-term goals of this study are to foster development and dissemination of evidence-based behavioral and pharmacological treatments to reduce HIV transmission, injection drug use (IDU), and heroin use in Russia. This study will examine the effects of combining behavioral therapy with naltrexone pharmacotherapy for the treatment of opiate dependence and reduction of HIV risks in opiate dependent individuals. Specifically the study will determine whether extended-release injection naltrexone has greater efficacy and is more cost-effective than oral naltrexone maintenance, whether behavioral drug and HIV risk reduction counseling (BDRC) combined with brief, medical management (MM) has greater efficacy and is more cost-effective than MM only, and whether particular combinations of medication formulation and counseling (MM only or MM plus BDRC) have greater efficacy or are more cost-effective than other combinations.

The aim of the study is to describe the effects of oxycodone/naloxone combination in comparison to oxycodone for the treatment of postoperative pain in patients undergoing cardiac surgery. The hypothesis is that the duration of opioid-induced bowel dysfunction and the need of laxatives will decrease.

Opioid dependence is a substantial problem associated with significant morbidity and mortality. Extended-release naltrexone has been found effective at reducing opioid use and maintaining abstinence, but its use has been limited by the difficulties encountered with treatment initiation, which involves detoxification from opioids and oral naltrexone titration. Improving the likelihood of a successful transition to naltrexone is therefore an important public health goal. N-methyl-D-aspartate receptor (NMDA) antagonism has been found to alleviate the signs and symptoms of withdrawal from opioids, as well as to address adaptations associated with chronic opioid use, such as opioid-induced hyperalgesia (increased pain sensitivity). These benefits may persist for at least 72 hours after a single dose. NMDA antagonism may therefore facilitate a rapid transition to naltrexone by reducing discomfort, improving motivation, and ameliorating adaptations associated with drug dependence, such as craving and arousal. The purpose of this trial is to assess the feasibility of NMDA antagonist-assisted naltrexone initiation in opioid dependent individuals. After administration of extended-release naltrexone, participants will be followed for 4 weeks, and transitioned to appropriate care subsequently (oral naltrexone, extended-release naltrexone).
