Chronic Pain Clinical Trials

This research project is intended to understand the mechanisms of action for the pain-relieving properties of visual green light exposure. The investigators have shown previously that greenlight exposure decreased acute and chronic pain in both animals and humans. However, the investigators do not yet understand how green light exposure is capable of such function. Read Less

Over 100 million Americans suffer from chronic pain resulting in annual cost of roughly $635 billion. Limited treatments are available for this widespread disease. The data supporting these treatments lack generalizability to patients with more serious medical and psychological comorbidities who are often excluded from explanatory efficacy trials. Our work aims to integrate randomized comparative effectiveness research with patient care. The investigators will randomize the patients and collect data using an open-source learning healthcare system already in use in our department to monitor patients' progress: Collaborative Health Outcomes Information Registry (CHOIR). Collaborative Health Outcomes Information Registry uses the National Institute of Health Patient Reported Outcomes Measurement Information System item banks for comparative metrics through computer adaptive testing. The investigators will leverage the advantage of this novel system to compare effectiveness of duloxetine and desipramine in decreasing pain in patients with chronic pain. The investigators will also compare adherence of patients to these two commonly used medications over a period of six months. This will evaluate feasibility of integrating randomized comparative effectiveness research with patient care in subspecialty clinics. Collaborative Health Outcomes Information Registry can then be applied for numerous future trials to advance our knowledge in perioperative and pain medicine. Read Less

This project proposes to systematically develop and evaluate the feasibility and preliminary effectiveness of a digitally delivered, graded exposure treatment for youth with chronic musculoskeletal pain, utilizing a sequential replicated and randomized single-case experimental design (SCED). SCED provides the opportunity to rigorously evaluate treatment effectiveness at the individual level. Development of iGET Living will be based on a series of short iterations, with alpha testing (Aim 1) on a small sample of adolescents with chronic pain (N = 15) and their parents (N = 15). For Aim 1, participants will participate in three, two hour focus groups (one per week over the course of three weeks), resulting in 6 total hours of participation per participant for Aim 1. Aim 2 will involve a sample (N = 20 youth, N = 20 parents) of naïve end-users. Participants will be enrolled in a baseline period ranging from 7-25 days (done to support SCED methodology) after which they will be enrolled in the online intervention program, lasting 6-weeks. Patients will be contacted 3-months post-discharge from treatment (week 22 of enrollment) and will complete self-report outcome measures at this time. Read Less

Spinal cord stimulation modulates the nervous system to effectively block pain signals originating from the back and legs. Spinal cord stimulation has been shown to improve chronic pain, improve quality of life, and reduce disability. Unfortunately, spinal cord stimulation has a high trial failure rate and a high long-term failure rate. This study consists of a prospective cohort of patients clinically scheduled to undergo spinal cord stimulation for the treatment of chronic back pain or radiculopathy. Participants will undergo a structured optimization evaluating existing types of stimulation (tonic, burst, and multistim). Each participant will try out all types of available stimulation but be blinded to the type. Over the course of four months, each participant will evaluate each type of stimulation by reporting daily pain scores. Thompson sampling will be used to identify which setting produces the biggest improvement in pain and recommend it for future use. Participants will follow up routinely to collect laboratory, behavioral, and survey responses to test for the feasibility of obtaining data explaining pain phenotype. Read Less

Chronic musculoskeletal pain (CP) is a major public health concern. Psychosocial treatments have been shown to be efficacious when compared to largely inert control conditions, but they are characterized by modest effects on primary outcomes. One strategy to boost efficacy is to increase our understanding of treatment mediators. Studies of mediators that directly compare different treatments with each other are needed to determine which mediators are treatment-specific, which are shared across treatments, and which contribute the most to clinical outcomes. Another strategy is to identify the patient characteristics that moderate treatment responses. Research is needed that is guided by theoretical models and that tests moderators across multiple treatments. Identifying subgroups of patients more likely to respond to one or another treatment can advance precision medicine by informing a priori patient-treatment matches that can optimize treatment effects. To accomplish these goals, the authors will conduct a randomized clinical trial to compare the mediators and moderators of the clinical effects of Cognitive-Behavioral Therapy (CBT), Acceptance and Commitment Therapy (ACT), and Emotional Awareness and Expression Therapy (EAET) on adults with chronic spinal (axial) pain. Following baseline assessment of outcome variables as well as potential mediators and moderators, 460 participants will be randomized to CBT, ACT, EAET, or treatment-as-usual control (TAU). The three treatments will be conducted as individual therapy provided weekly for 8 weeks via telehealth. The researchers will conduct weekly assessments of both potential mediators and outcomes, as well as post-treatment and 6-month follow-up assessments. The goal of the study is to identify the most powerful treatment mechanisms - specific and shared -- and reveal for whom the mediator-outcome pathways are strongest.This project can increase the effects of our psychosocial chronic pain treatments by identifying the most effective treatment mechanisms and by informing patient-treatment matches that can optimize treatment effects.

Both mindfulness-based interventions and light physical activity have been shown as effective in reducing the burden of chronic pain. This proposed intervention, mindful walking (MW), is a combination of physical activity and mindfulness-based intervention aimed at reducing pain with a non-pharmacological approach. In MW, mindfulness-based instructions emphasized acknowledging arising thoughts, feelings, and/or emotions without judgment or emotional reaction and to "simply return their attention back to the footstep" sensation whenever such discursive events occur. Furthermore, subjects will be taught that perceived sensory and affective events were "momentary" and "fleeting" and do not require further interpretation or evaluation. Read Less

The purpose of this randomized pragmatic trial is to assess the effect of monthly booster contacts on long-term Brief Cognitive Behavioral Therapy for Chronic Pain (BCBT-CP) pain outcomes compared to BCBT-CP without a booster in 716 Military Health Systems (MHS) beneficiaries referred to a Behavioral Health Consultant (BHC) for pain management using BCBT-CP. Patients will be randomly assigned to receive either standard BCBT-CP (working with a BHC in the medical home clinic) or standard BCBT-CP with adjunctive monthly booster contacts. Additionally, patient participants and clinic providers and staff will be offered the opportunity to participate in separate post-treatment Focus Groups using a semi-structured interview format designed to assess the usability, ease of use, perceived effectiveness, helpfulness, and barriers to the pain management intervention. Patient participants will be assessed 3-, 6-, 12- and 18-Months following their first appointment for BCBT-CP. Read Less

Quantitative Sensory Testing (QST) is a novel investigative technique used in other pain conditions to evaluate patterns of chronic pain, and in this study will be used to elucidate pain patterns in patients with Chronic Pancreatitis (CP). QST uses a specific series of standardized stimulations to map the pain system. QST has the potential to change and improve the treatment paradigm for patients with CP and may eventually be able to predict response to invasive CP therapies. Read Less

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. Read Less

This is an open-label, single center design. In the first stage, five (5) healthy individuals will receive a microdose (10µg) of [11C]-NOP46, immediately followed by whole body positron emission tomography (PET)/computed tomography (CT) to determine dosimetry and perform an initial safety evaluation of the radiotracer. If no toxicities develop, then the investigation will move to the second stage, in which thirty (30) patients with chronic pain will receive a microdose of [11C]-NOP46 followed by PET/CT of region of interests.

The goal of this pilot clinical trial is to learn whether vitamin D is able to prevent chronic pain following burn injury and to determine what biological mechanisms are engaged by Vitamin D following burn injury. The main question[s] it aims to answer are: Is the clinical trial protocol feasible? Is Vitamin D administration following burn injury safe? How does vitamin D cause changes in the immune system in the aftermath of burn injury? Following informed consent, participants will be asked to: Take 6 capsules by mouth one time following burn injury (Vitamin D or Placebo) Provide a blood sample at baseline and 6 weeks following injury Fill out surveys daily while in the hospital, weekly through 6 weeks, and at 3 months and 6 months. Researchers will compare Vitamin D and placebo groups to see if there are differences in adverse effects (side effects), chronic pain, and profiles of immune cells from collected blood samples.
