Filter by: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).
Nearly 9 of every 10 pregnant opioid-dependent women report that the current pregnancy was unintended and the majority of non-pregnant opioid-maintained women do not use contraception or use less effective methods like condoms. This proposal aims to further test a novel contraceptive management program to increase use of more effective contraceptives among opioid-maintained women at risk of unintended pregnancy.
Opioids are the most commonly utilized pharmacological treatment for moderate to severe pain. However, their clinical value is hindered by the development of opioid-induced hyperalgesia (OIH). OIH manifests as heightened pain sensitivity, and is an increasingly challenging drawback to the efficacy of opioid treatment. Although the mechanism of action modulating OIH is not completely understood, previous animal studies suggest that this phenomenon is a result of proinflammatory responses. Thus, administering an adjunct anti-inflammatory agent may attenuate OIH. Minocycline is one such agent; it is a tetracycline derivative antibiotic that inhibits microglia activation, nitric oxide (NO) production, and the release of pro-inflammatory cytokines and chemokines. In fact, recent evidence suggests that minocycline may attenuate the neuroinflammatory effects of opioids while enhancing their antinociceptive effects. Therefore, the investigators will determine if minocycline will mitigate OIH in methadone-maintained patients.
This is a randomized, double-blind, placebo controlled, multicenter study in male and female participants who are seeking treatment for opioid use disorder.
This study evaluates the biological markers of treatment of opioid dependent individuals with an extended release formulation of the opioid antagonist naltrexone. The biological measures include functional MRI, blood levels of naltrexone and its metabolites, urine toxicology and behavioral tests probing various aspects of personality, memory, reward processing and attention.
The investigators will randomize 50 opioid-dependent participants who have initially failed outpatient induction onto XR-NTX; participants will receive buprenorphine/naloxone on a weekly basis for 30 days. Buprenorphine/naloxone will be dispensed weekly during the 30-day stabilization and twice weekly during taper phase, and all patients who successfully complete the detoxification will be offered induction onto XR-NTX. All participants will receive weekly therapy with a study psychiatrist. All participants will receive open-label medication. The primary outcome of this study will be percentage of patients successfully inducted onto XR-NTX. Secondary outcomes will be time to relapse, defined as opioid use or dropout.
There has been a dramatic rise in opioid overdose (OOD) deaths in recent years. Attempts to ameliorate the problem have largely focused on increasing the accessibility of naloxone, an opioid antagonist that is effective in OOD reversal. Individuals who have experienced a non-fatal OOD are at risk for additional overdoses and yet there are no interventions that specifically target this high-risk population. To address this gap, the investigators have developed the "Tailored Telephone Intervention delivered by Peers to Prevent Recurring Opioid Overdoses" (TTIP-PRO). The overall goal of the present study is to conduct a pilot evaluation of the TTIP-PRO. The research literature suggests the need for an intervention targeting patients experiencing a non-fatal OOD.
This study uses an artificial intelligence platform to automatically confirm medication ingestion. The Health Insurance Portability and Accountability Act (HIPAA)-compliant platform can be downloaded as an 'app' onto any smartphone to automate directly observed therapy (Automated DOT®). Real-time patient adherence data are encrypted and automatically sent to a centralized web-based dashboard for use by healthcare professionals or research staff. Unlike Facetime® or Skype®, the system relies on computer vision algorithms to confirm the process of medication administration; no human review is necessary. The purpose of this study is to evaluate the feasibility and acceptability, and measure the accuracy, of the AiCure platform ("platform") in patients being treated for opioid dependence with Zubsolv® over the course of 12 weeks. The following aims will be tested: 1) to assess the feasibility and acceptability to both participants and study staff in using AiCure to monitor medication adherence; 2) to evaluate the acceptability of using AiCure to optimize care pathways; and 3) to measure the reliability and validity of AiCure in detecting interruptions in treatment. To assess feasibility and acceptability of the platform, we will measure rates of physician satisfaction and user acceptance. Optimization of care pathways will be measured by assessing the sustainability of AiCure use over 12 weeks (retention rates) and measuring illicit opioid use (urine drug screens) compared to historical data. Reliability and validity of AiCure will be measured by comparing AiCure adherence against pharmacokinetic data. All participants will be requested to take each of their prescribed doses using the app. Participants will be able to download the app onto their own smartphone or will be provisioned a device at the start of the study. The data captured during the medication ingestion process will be automatically encrypted and stored on the participant smartphone and uploaded wirelessly to a cloud-based dashboard. If a participant is non-adherent (missed dose, incorrect dosage) or if suspicious behavior is detected, an automated alert will be sent to study staff via email or SMS to prompt immediate intervention. In addition, all participants will receive treatment as usual.
Background: Although substitution therapy has been shown to be highly effective to retain opioid-dependent patients in treatment and reduce drug use, this population is afflicted by numerous conditions including depression. Unfortunately, studies published thus far have reported inconsistent or no difference in response between placebo therapy and antidepressants such as selective serotonin reuptake inhibitors. Objective: To assess the feasibility of Desvenlafaxine (DESV) administration among opioid-dependent subjects and explore its effect on depressive symptoms. Methods: Open-label pilot trial of 8 weeks of DESV 50-100 mg/day in 20 methadone-maintained individuals with comorbid depressive symptoms at the Centre hospitalier de l'Université de Montréal. Significance: This pilot study will lay down the foundation on which a larger multisite clinical trial could be conducted to examine DESV as new treatment for opioid-dependent population with comorbid depression.
Buprenorphine/naloxone (BUP/NLX) treatment is effective for the treatment of prescription opioid dependence, previous studies have not determined the optimum dose of BUP/NLX for this patient population. The goal of this study is to determine if there are differences in clinical efficacy of BUP/NLX tablet in low dose range (less than or equal to 8/2mg) vs. high dose range (greater than or equal to 16, range 16-24mg). The main outcomes of interest will be treatment retention, use of opioids, and the use of other drugs of abuse.
