Filter by:This is an outpatient randomized within subject placebo-controlled human laboratory investigation of analgesia (as assessed with quantitative sensory testing; QST) from ketamine alone and in combination with hydromorphone in buprenorphine maintained participants. The goals of this project are to characterize the analgesic, subjective, and physiologic effects of ketamine combined with hydromorphone in patients on buprenorphine maintenance for opioid use disorder.
Despite the availability of opioid replacement therapies, many opioid use disordered Veterans are not able to remain abstinent. Repetitive Transcranial Magnetic Stimulation (rTMS) is a non-invasive neuromodulation technique with a consistent, rapidly expanding literature base reporting positive outcomes in substance using populations. This pilot application will investigate a novel multi-session rTMS paradigm to determine feasibility and tolerability of this intervention in opioid use disordered Veterans.
This is a Phase 3b, open-label study in patients that present to the ED for an opioid OD and receive treatment with an opioid antagonist. The study is designed to determine effect of SUBLOCADE on repeat overdose and death compared to historical control data. The study will assess subjects that receive acute administration of SUBOXONE sublingual film in the Emergency Department (ED) followed by SUBLOCADE administration in the ED and referral to an affiliated outpatient treatment clinic, compared to historical control data from electronic health records.
In a sample of individuals with co-occurring OUD and mental disorders, the investigators plan to test two medications for opioid use disorder (MOUD) treatment protocols that involve differing approaches to the use of opioids and other drugs during and after stabilization on MOUD - intensive vs. moderate treatment.The study is being conducted alongside the opening of a new clinical service funded by the Substance Abuse and Mental Health Services Administration (SAMHSA) known as the Addiction and Behavioral Health Outpatient Recovery (ABOVE) program. The ABOVE Program is designed to treat patients with co-occurring opioid use disorder (OUD) and mental disorders with MOUD. Participants are individuals seeking treatment for co-occurring opioid use disorder (OUD) and mental disorders and are willing to receive MOUD treatment. Potential participants will be screened in the context of clinical care for opioid use disorder and mental disorders. If they are eligible for treatment in the ABOVE program, they will be asked to complete a baseline assessment, again for the purposes of clinical care. After completing the baseline clinical assessment, they will be asked to participate in this clinical trial, consented, then randomized. Treatment is delivered in the context of clinical care which involves delivery of MOUD and can involve psychiatric medications, and group and individual psychotherapy. Difference in treatment between the two randomization arms will only occur if a relapse to drug use occurs and will only involve two protocol-directed treatment responses to relapse.
Healthy, adult men and women, aged 21 to 59 years, who abuse opioids and are physically dependent on them will be recruited to participate in a study to examine the ability of doxazosin, an epinephrine receptor blocker, to alter the abuse potential of oxycodone. After participants complete the screening process, they will be scheduled for inpatient admission onto our clinical inpatient where they will reside during the 8-week study. During Weeks 1-2, participants will be transitioned from their normal opioid use regime onto oral morphine until withdrawal dissipates. At this time participants will also be stabilized on the first dose of doxazosin (0 or 16 mg/day; active doxazosin will be started at 4 mg and increased by 4 mg every 3 days). During Weeks 3-4, either active or placebo oxycodone will be available (in random order). Monday-Friday each these drugs will be tested using our sample and choice self-administration procedure. On Friday, participants will also complete a cue exposure session during which they will be presented drug cues to determine whether the study medication affects how participants react to them. To summarize, Weeks 1-2 and 5-6 will be stabilization weeks (0 or 16 mg doses of doxazosin administered in random order) and Weeks 3-4 and 7-8 will be test weeks under each of the doxazosin maintenance doses. At the conclusion of the study, participants will be given an exit interview, warnings about re-initiation of opioid use, and counseling about the different treatment options for Opioid Use Disorder. Within 1 week after discharge, investigators will assess adverse events using the a number of clinical assessments. At each weekly visits, investigators will assess participants' interest in treatment and drug use patterns.
The study will enroll 30 opioid-dependent participants into an open-label pilot outpatient study of methods to facilitate induction and stabilization onto XR-NTX. There will be three different methods of XR-NTX induction using increasing doses of oral naltrexone and buprenophine.
The purpose of this study is to examine whether buprenorphine can be at least as effective as other opioid medications in relieving chronic pain in patients who suffer from dependence on their opioid medications, while patients simultaneously experience progressive decline of pain along with absence of opioid withdrawal symptoms and improved quality of life.
