Chronic Pain Clinical Trials

Chronic pain is associated with plasticity in the brain limbic system composed mainly of the amygdala, hippocampus, ventral striatum, and cingulate cortex (ACC) /medial prefrontal cortex (mPFC). These brain areas, especially the ventral striatum, receive dopaminergic input from the ventral-tegmental area (VTA). Although there is a significant literature now showing that limbic brain tracks chronic pain intensity and predicts the risk of transition from sub-acute to chronic pain, the role of dopaminergic input to the limbic brain and the change thereof which occurs in chronic pain, is still not clear. Given the role of dopamine in motivational control and the loss of motivation associated with chronic pain understanding how dopaminergic transmission is altered in the limbic brain of chronic pain patients is critical to the understanding of the pathophysiology of chronic pain. Therefore, the overall aim of this project is to use brain imaging to study how dopaminergic transmission through the oral administration of pro-dopaminergic medications carbidopa/levodopa (CD/LD) and methylphenidate will modulate the brain signature of chronic pain. Chronic pain subjects will be scanned at baseline (no drug administration) and three times after treatment with the two drugs or placebo. The protocol will follow a randomized double-blind approach.

The primary objective of this phase 2 study is to investigate the therapeutic potential of orally administered combined delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) in relieving both pain and cue-induced opioid craving in people with co-occurring opioid use disorder (OUD) and chronic pain who are undergoing methadone therapy.

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

Abdominal pain in chronic pancreatitis (CP) affects up to 90% of patients during the course of their disease, and response to currently available therapies is suboptimal and unpredictable. The proposed clinical trial will evaluate the predictive capability of Pancreatic Quantitative Sensory Testing (P-QST) - a novel assessment of neurosensory phenotyping- for improvement in pain in patients with CP who are undergoing medically-indicated invasive treatment with endoscopic therapy or surgery.

The goal of this interventional clinical trial is to assess opioid consumption 24-48 hrs post anesthesia block among patients undergoing total knee arthroplasty. The main question it aims to answer is: 1. Is there a difference in opioid consumption 24-48 hours post block administration among patients that receive an adductor canal catheter (ACC) versus adductor canal block (ACB)? Participants will be: * Randomized to receive an adductor canal catheter (ACC) or a sham adductor canal catheter. * Asked to use the Diagnotes application to communicate with the pain doctor while the catheter is in place. * Follow up for up to 6 months post-operation. Researchers will compare the interventional group (ACC) to the control group (sham ACC + ACB) to see if there is difference in opioid consumption and chronic pain at 6 months post-operation.

This is a pragmatic, open label, randomized controlled trial with 1:1:1 allocation to 12 weeks of: (1) onsite yoga at opioid treatment programs (OTPs), (2) onsite physical therapy (PT) at OTPs, or (3) treatment as usual (TAU). Participants will be 345 individuals with chronic back pain receiving treatment for opioid use disorder (OUD) in community-based OTPs. Through research visits at screening, baseline, and months 1, 2, 3, 6, and 9, the investigators will evaluate pain and opioid use outcomes and implementation outcomes. Read Less

The proposed IMPOWR Research Center at Montefiore-Einstein (IMPOWR-ME) will create a multidisciplinary and synergistic program of research to test multimodal treatments that address both chronic pain and opioid use disorder. IMPOWR-ME will generate critical knowledge about the effectiveness, implementation, and cost effectiveness of providing Acceptance and Commitment Therapy and/or a care management smartphone app for individuals in primary care-based buprenorphine treatment. Patients with lived experience with chronic pain and/or opioid use disorder, patient and policy advocates, payors, and health system partners will be engaged in all stages of the research. IMPOWR-ME is well-positioned to become a long-lasting hub for stakeholder-engaged research with multidisciplinary senior and early stage investigators focused on reducing overdose through better treatments for OUD and CP.

The purpose of this study will be to investigate the optimization of spinal cord stimulation with ECAPs in patients with spinal cord implants. Read Less

The purpose of this study is to test whether yoga can reduce nerve pain caused by cancer treatment (chemotherapy-induced peripheral neuropathy, or CIPN). Participants will take one of three approaches: * Yoga classes * Educational sessions on the causes and impacts of CIPN, how yoga may help with CIPN, and how different therapies may help with CIPN * Usual care with standard-of-care medications for CIPN The researchers will compare how these different approaches affect participants' balance, their risk of falls, and their quality of life. This study will also measure how much yoga can help the reduced sense of touch caused by CIPN. The functional assessments TUG and CTS can be safely completed either virtually and in-person and will be mandatory for all patients. The functional assessment FRT and QST assessments that can only be completed in-person are optional at these time points. Read Less

This study will comprehensively investigate the insula as a brain target for neuromodulation to treat chronic neuropathic pain. Read Less

Yoga Nidra is a scripted mind-body intervention (MBI) that uses guided relaxation technique in a reproducible sequence of mechanisms that naturally produce a parasympathetic response. This is a randomized controlled trial in which participants will be randomly assigned to one of three interventions: 1) yoga nidra (Yoga Nidra Script Basic), 2) yoga nidra with pain acceptance (Yoga Nidra Acceptance Intention), 3) yoga nidra with pain acceptance and Explicit Motor Imagery (Yoga Nidra Acceptance Intention and Visualization).
