Active clinical trials for "Opioid-Related Disorders"

This study examines the comparative effectiveness of opioid review programs in reducing unsafe opioid prescribing in two states: prospective prior authorization (PA) with hard stops in Washington and retrospective review (RR) with prescriber notification in Ohio.

Medication Assisted Treatment (MAT) of Veterans with Opioid Use Disorder (OUD) decreases mortality and improves treatment follow-up. However, outside of large and/or urban VA medical centers, there are shortages of providers with experience treating OUD and a license to prescribe buprenorphine. This has resulted in decreased access to MAT (buprenorphine/naloxone and injectable naltrexone) at rural CBOCs and increased overdose rates in rural areas. Some individual prescribers have used clinical video teleconferencing (CVT) to overcome geographic barriers and prescribe MAT to Veterans in CBOCs. However, while locally effective, these arrangements are not standardized and are not parts of larger VISN-wide or national VHA strategies. This proposal describes an effective program that the investigators propose to replicate and expand. The program involves increasing prescribing rates of MAT for OUD in CBOCs using telemedicine. The investigators propose to (A) develop materials and procedures for the dissemination of telemedicine delivery of MAT to Veterans at CBOCs and (B) implement telemedicine prescribing of MAT at rural CBOCs in Northern Maine that lack on-site MAT providers. MAT will be prescribed by the VISN 1 Telemental Health Hub, which already provides medication management, psychotherapy, and some MAT to sites in Northern Maine. In later years, the program will be expanded to other VISN 1 CBOCs, and to other TMH Regional Hubs that provide services to wide catchment areas in other VISNs. By building on an existing infrastructure connecting these TMH Regional Hubs to CBOCs and collaborating with other national initiatives (e.g. SCAN ECHO, PDSI, and academic detailing), telemedicine MAT will be rapidly disseminated to Veterans at CBOCs who are at high risk for illness, overdose, and premature death from opioids.

Methadone maintenance therapy (MMT) is one of the modalities to prevent HIV transmission among injected drug users, particularly in opioid-dependent users. However, methadone-associated cardiotoxicity is one of the fatal adverse events that limit the widespread usage in certain groups of opioid-dependent patients. This is a cross-sectional study aimed to investigate the association between 4 KCNH2 SNPs (1539C>T, in exon 6 of KCNH2 gene; 1956T>C, in exon 8 of KCNH2 gene), 2350C>T (in exon 9 of KCNH2 gene), 2690A>C (Exon 11 of KCNH2 gene)) and prolongation of QTc interval in opioid-dependent Kelantanese Malays who are the recipients of Methadone Maintenance Therapy. The investigators hypothesized that subjects with minor alleles of those 4 SNPs will have longer QTc intervals than those with major alleles, adjusting for the effects of other confounding factors such as age and gender of the subjects, plasma methadone trough levels, hypokalemia, hypocalcemia and hypomagnesemia. The investigators also aimed to provide a model that will reliably predict the magnitude QTc based on the SNPs data and other covariates mentioned above. This will greatly assist in identifying methadone recipients who are at risk of developing prolonged QTc or the more fatal torsade de pointes.

The goal of this project is to develop a multicomponent stigma reduction intervention to address intrapersonal (individual) stigma regarding Opioid Use Disorder (OUD). The intervention will address this cost/benefit evaluation among individuals known to face intersecting stigma of OUD and African American race, with treatment elements chosen explicitly to increase the value of treatment using salient forms of reward, and to ease perceived costs through explicit services in an effort to encourage the occurrence of the first treatment visit for OUD.

The purpose of this study is to provide medication for opioid use disorder (MOUD) with buprenorphine and naloxone, or bup/nx, and pre-exposure prophylaxis (PrEP) for HIV prevention for persons who inject opioids accessing syringe services programs (SSPs), as part of a comprehensive harm reduction program, and assess the acceptability and feasibility of using telemedicine to implement the program. The initial visit will be conducted in person or remotely via telemedicine given COVID-19 protocols at the SSP sites in Charlotte and Wilmington, North Carolina (NC); follow-up visits will be conducted via telemedicine.

The purpose of this study is to evaluate the usability of an interactive smartphone application (app) designed to engage and support patients receiving bup/nal.

Only limited information on the process of completing long-term opiate substitution treatment (OST) with substances like methadone exist. Furthermore, systematic knowledge from scientific studies is scarce, there are only few studies with respect to treatment completion or regular termination (mainly catamnestic analyses). Studies by Nordt et al. (2004) or Nordt & Stohler (2006) show an estimated rate of 10% of patients per year who terminate OST by means of tapering the substitution agent or changing into withdrawal treatment in specialized clinics. It is state of the art that an indication for termination of OST has to be based on a common agreement between the patient and the doctor. Furthermore, the patient should live in a stable social situation and the state of health had markedly improved. Finally, the patient has to be free of (illegal) drug use for at least 6 months and the individual aims of treatment should have been reached (Vader et al. 2003). The main objective of the prospective and explorative study is the systematic description of the process of termination of OST. With a comparison between patients who complete OST regularly and patients who terminate treatment prematurely (or are still in treatment) predictors of positive termination of OST can be identified. Patients treated with methadone or levomethadone of 5 general practitioners' practices and 2 specialized clinics who might be able to terminate OST during the next 12 months from the doctors' perspective can take part in the study. In addition to baseline examination further assessments take place every 3 months (i.e. after 3, 6, 9 and 12 months). The questionnaires include state of health, well-being, social situation as well as drug and alcohol use. Furthermore, the treating doctors are asked every 3 months to fill out questionnaires on infections and other disorders, clinical characteristics, dosage process and drug use (measured by urine samples). Patients who will be successful in completing OST during the observational period will be compared with the remaining cases. Finally, a 6-month follow-up is planned in order to investigate the stability and maintenance of the situation at month 12.

The purpose of this study is to assess the risks of abuse, misuse and adverse events related to high dose buprenorphine. Approximately 1250 patients taking Subutex (Schering-Plough) or its Buprenorphine High Dose (BHD) generic (Arrow Laboratories) will participate in this study. Data will be collected using physician questionnaires and self evaluation patient questionnaires at the first visit and visits at 6 and 12 months.

The purpose of this treatment research study is to assess the effectiveness of buprenorphine maintenance treatment for opioid dependence delivered in a primary care clinic setting. This study will determine whether buprenorphine treatment in primary care is effective in reducing cravings, reducing illicit opioid use, reducing addiction severity, and retaining patients in primary care treatment for opioid dependence.

The investigators hypothesize that a well-designed hepatitis C (HCV) video education curriculum for active drug injectors will lead to measurable improvements in HCV testing rates, HAV and HBV vaccination rates, as well as knowledge and attitudes about this condition. The investigators will use a short 10 minute video designed for active drug users to and assess its impact vs. a usual-care counseling intervention. The investigators will measure and compare its impact at baseline, 4 weeks after video viewing, and 12 weeks after intervention.
