Opioid Use clinical trials at UCSD

Managing Opioid Related Sleep Apnea With Acetazolamide
open to eligible people ages 18 years and up
Patients with chronic pain who use opioids appear to be at increased risk for breathing issues during sleep, termed sleep disordered breathing (SDB). Treatment of SDB often consists of use of a device during sleep that provides continuous positive airway pressure (CPAP) via a mask interface. However, this device is not effective or tolerated in all individuals. The goal of this study is to examine whether a medication called acetazolamide can improve SDB, as an alternative to CPAP treatment. The investigators will measure the improvement in SDB, as well as any change in symptoms, during a 1 week treatment with acetazolamide compared with 1 week of placebo (sugar pill). This study will help to provide data for longer term studies of treatment for SDB in patients who use opioids.

Leveraging Artificial Intelligence and Multi-Omics Data to Predict Opioid Addiction
open to eligible people ages 18 years and up
The primary goal of this proposal is to validate a novel genomic and microbiome predictive model that may be used to assess a person's risk of developing opioid use disorder (OUD). The following will be tested: (1) MODUS (Measuring risk for Opioid use Disorder Using SNPs), which is a genomic panel consisting of a set number of proven single nucleotide polymorphisms (SNP) that utilizes machine learning to determine an individual's risk; and (2) MICROUD (MICRObiome for Opioid Use Disorder), which will be a novel microbiome prediction panel for OUD risk. MODUS and MICROUD will be developed using existing public datasets with genomic and microbiome data (e.g., All of Us, Human Microbiome Project). During development of these predictive models, in parallel, an external prospective validation cohort will be recruited consisting of subjects from the University of California, San Diego, Veteran Affairs of San Diego, and Veteran Affairs of Palo Alto (each site with separate IRB). The hypothesis is that MODUS and MICROUD will have high predictive potential for identifying high risk patients for OUD.

"Bupe by the Book": A Tele-Buprenorphine Clinical Trial in Public Libraries With Unstably Housed Persons With Opioid Use Disorder
Sorry, in progress, not accepting new patients
Public libraries nationwide are facing an on-premise opioid overdose crisis. Many persons with opioid use disorder (OUD) remained unhoused and profoundly hard to reach. This study innovatively develops and tests a telemedicine intervention delivered through public libraries to increase unstably housed individuals' access to bupe treatment that would prevent overdoses from occurring in the first place. The investigators will conduct a 12-week pilot 2-arm randomized controlled trial (RCT) (n=40). Research staff will recruit library patrons and randomize them to weekly telehealth at the library or in-person clinic control arms across two participating libraries in San Diego.

Improving Postamputation Functioning by Decreasing Phantom Pain With Perioperative Continuous Peripheral Nerve Blocks: A Department of Defense Funded Multicenter Study
Sorry, accepting new patients by invitation only
When a limb is amputated, pain perceived in the part of the body that no longer exists often develops, called "phantom limb" pain. The exact reason that phantom limb pain occurs is unclear, but when a nerve is cut-as happens with an amputation-changes occur in the brain and spinal cord that are associated with persistent pain. The negative feedback-loop between the injured limb and the brain can be stopped by putting local anesthetic-called a "nerve block"-on the injured nerve, effectively keeping any "bad signals" from reaching the brain. A "continuous peripheral nerve block" (CPNB) is a technique providing pain relief that involves inserting a tiny tube-smaller than a piece of spaghetti-through the skin and next to the target nerve. Local anesthetic is then introduced through the tiny tube, which bathes the nerve in the numbing medicine. This provides a multiple-day block that provides opioid-free pain control with no systemic side effects, and may prevent the destructive feedback loop that results in phantom limb pain following an amputation. We propose a multicenter, randomized, triple-masked (investigators, subjects, statisticians), placebo-controlled, parallel arm, human-subjects clinical trial to determine if a prolonged, high-concentration (dense), perioperative CPNB improves post-amputation physical and emotional functioning while decreasing opioid consumption, primarily by preventing chronic phantom limb pain.

Virtual Reality Cognitive-Affective Training for Opioid Use Disorder- A Phase 2 RCT
Sorry, in progress, not accepting new patients
The goal of this clinical trial is to examine the usefulness of a virtual reality-delivered intervention for individuals with opioid use disorder who are taking medication. The main question it aims to answer is will people with opioid use disorder who receive the study intervention, Mindfulness-Oriented Recovery Enhancement in Virtual Reality (MORE-VR), have fewer days in which they use opioids than will people who just receive their usual treatment. Participants will be randomly assigned to either receive 8 weekly sessions of MORE-VR in addition to their usual treatment, or treatment as usual only. Researchers will compare these groups at the end of treatment and three months after treatment is over on number of days of opioid use and time until first opioid use lapse, as well as drug craving and mood.
