Active clinical trials for "Opioid-Related Disorders"

The aim of the present study is to assess the availability of cannabinoid receptors (CB1R) in the human brain. CB1R are present in everyone's brain, regardless of whether or not someone has used cannabis. The investigators will image brain cannabinoid receptors using Positron Emission Tomography (PET) imaging and the radioligand OMAR, in healthy individuals and several conditions including 1) cannabis use disorders, 2) psychotic disorders, 3) prodrome of psychotic illness and 4) individuals with a family history of alcoholism, 5) Post-Traumatic Stress Disorder 6) Opioid Use Disorder using the PET imaging agent or radiotracer, [11C]OMAR. This will allow us to characterize the number and distribution of CB1R in these conditions. It is likely that the list of conditions will be expanded after the collection of pilot data and as new data on cannabinoids receptor function and psychiatric disorders becomes available. Those in the cannabis us disorder arm of the study will have a PET scan on at least three occasions: once while smoking as usual, once after 48-hours of abstinence from cannabis, and a final time after 4 weeks of abstinence. Additional scans may be conducted within the 4 weeks and the last scan may be conducted well beyond 4 weeks. Similarly, while most schizophrenia patients may get scanned just once, a subgroup of patients may get scanned more than once. For example to tease out the effects of medications, unmedicated patients may get scanned while unmedicated and again after treatment with antipsychotic medications. Similarly prodromes may get scanned while in the prodromal stage off medications, on medications and after conversion to schizophrenia.

The purpose of this study is determine the safety, efficacy and tolerability of a novel drug APH-1501 as a pharmacotherapy for Opioid Dependence. The investigators will evaluate the safety of escalating doses APH-1501.

Background: The chemical messenger dopamine carries signals between brain cells. It may affect addiction. Heavy use of pain medicines called opioids may decrease the amount of dopamine available to the brain. Researchers want to study if decreased dopamine decreases self-control and increases impulsiveness. Objective: To learn more about how opiate use disorder affects dopamine in the brain. Eligibility: Adults 18-80 years old who are moderate or severe opiate users Healthy volunteers the same age Design: Participants will first be screened under another protocol. They will: Have a physical exam Answer questions about their medical, psychiatric, and alcohol and drug use history Take an MRI screening questionnaire Give blood and urine samples Have their breath tested for alcohol Participants will have up to 3 study visits. They will have 2-3 positron emission tomography (PET) scans. A radioactive chemical will be injected for the scans. Participants will lie on a bed that slides in and out of the donut-shaped scanner. A cap or plastic mask may be placed on the head. Vital signs will be taken before and after the PET scans. Participants will get capsules of placebo or the study drug. They will rate how they feel before, during and after. Participants will have their breath and urine tested each day. Participants will have magnetic resonance imaging (MRI) scans. They will lie on a table that slides into a cylinder in a strong magnetic field. They may do tasks on a computer screen while inside the scanner. Participants will have tests of memory, attention, and thinking. Participants will wear an activity monitor for one week....

This research study aims to learn more about opioid use disorder (OUD) during pregnancy and how outcomes for pregnant women and their newborns can be improved. During pregnancy, people with OUD are prescribed medication-assisted therapy (MAT). The investigators are interested to know how the medication is broken down by the body during pregnancy and how effective it is. The investigators also want to learn if this medication and OUD have any effect on the different parts of the brain when compared to mothers without OUD.

This pilot trial will explore the feasibility, acceptability, and effectiveness of the most recently approved formulation of injectable extended-release buprenorphine (XR-BUP) for treatment of opioid use disorder (OUD) in rural settings. We will randomize 144 eligible individuals with moderate to severe OUD in a 2:1 ratio to one of two medication conditions: (1) XR-BUP (128mg target), administered every 4 weeks or (2) SL-BUP (16mg-24 mg/day target).Participants will receive study medication treatment for the 14 week-intervention period, including an initial ~2-week period of induction/stabilization. The study will use a mixed-methods approach (participant assessments, study medication records, qualitative interviews) for assessing feasibility and acceptability, and results will include patient outcome data on the comparative effectiveness of XR-BUP versus SL-BUP for patients with OUD in rural settings.

The overarching goal of the study is to develop, pilot, and evaluate an intervention that aims to retain patients who initiate buprenorphine at Denver Health in ongoing treatment for opioid use disorder.

ED-initiated buprenorphine with brief intervention and facilitated referral to treatment has been shown to be highly successful in increasing treatment engagement rates and reducing opioid use among adults. It is unknown whether this intervention is similarly effective for adolescents with OUD. To rigorously examine this important clinical research question, it is first necessary to optimize this intervention for the adolescent population. In this R34 proposal, we will use the Assessment-Decision-Administration-Production-Topic Experts-Integration-Training-Testing (ADAPT-ITT) framework-a systematic method for intervention adaptation- to adapt (Aim 1) and test the feasibility (Aim 2) of a treatment strategy for adolescents that has been shown to effectively link adults with OUD to ongoing addiction treatment.

The objective of this study is to design, implement, and pilot test a multi-faceted intervention to support safer opioid prescribing, self-administration, and monitoring and reduce persistent opioid use and opioid use disorder for patients transitioning to the community setting after major orthopedic surgery. The multi-faceted intervention includes: 1) communication with outpatient providers and counseling of patients and caregivers at hospital discharge; 2) standardized opioid prescribing discharge order sets for each type of surgery; 3) an outpatient pain management follow-up visit embedded within routine post-operative care for managing pain and opioid use, and 4) a mobile patient-reported outcomes application for assessing pain, function, and possible development of opioid use disorder (OUD). The primary outcome will be persistent opioid use (in the 6 months after surgery) based on state-wide prescription data. Secondary outcomes will include the total morphine-equivalent dose of opioids prescribed at discharge; total post-operative opioids dispensed in the 6 months after surgery; and self-reported opioid misuse, pain and function 90 and 180 days after surgery.

This study will evaluate the feasibility of an app that provides drug information to people in recovery from opioid use disorder. This study is designed to test the prototype app, not to determine health outcomes. The study will confirm the design and operating specifications prior to being evaluated in a larger clinical trial.

This study will compare in-person induction and maintenance dosing of sublingual buprenorphine to induction and maintenance dosing of sublingual buprenorphine through comprehensive telehealth sessions and telehealth medication for opioid use disorder (MOUD).
