Neuropathic Pain Clinical Trials

This study aims to assess how use of spinal cord stimulation for the treatment of chronic pain impacts brain structure and function. The investigators will use a non-invasive neuroimaging technique called resting state Near Infrared Spectroscopy and Electroencephalography (rs-fNIRS/EEG). The investigators will enroll Veterans who are currently receiving care at the Medical Center and who are either long term users of SCS for the treatment of their chronic pain or being evaluated for use of SCS to treat their pain.

The objective of this study is to assess the effect Spinal Cord Stimulators have toward improving vascular changes of diabetes mellitus in patients eligible for SCS placement based on their condition of painful diabetic neuropathy; we will evaluate improving their disability and quality of life, improving micro-circulatory changes induced by Diabetes Mellitus (DM), improving macro-circulatory changes induced by DM and improving arterial stiffness of the vessels of the lower extremity.

The goal of this clinical trial is to evaluate safety and tolerability of multiple oral doses of EC5026 in male and female patients with neuropathic pain due to spinal cord injury. The main question it aims to answer is whether EC5026 is safe and well tolerated in SCI patients with neuropathic pain. In addition, this trial will also study the effects of EC5026 on pain. Researchers will compare EC5026 to placebo. Participants will be asked to: Take EC5026 or placebo in a masked fashion, once daily, for 14 consecutive days. Undergo physical exams, vital signs assessments, ECGs, and blood draws Complete assessments of pain, sleep, functional status, and perception of change Read Less

This is a two-arm randomized clinical trial in which 80 participants with Vitamin D deficiency and scheduled to begin taxane-based chemotherapy will be randomized to either: 1) prescribed vitamin D replacement or 2) standard of care. Read Less

This application addresses the Peer Reviewed Medical Research Program Investigator-Initiated Research Award FY21 W81XWH-22-CPMRP-IIRA area of Chronic Pain Management Research Program- The investigators will utilize subjects who have sustained ankle fractures and may develop chronic pain following bone union. No attempt will be made to affect the experimental outcome in the subjects. This study will adhere to a core set of standards for rigorous study design and reporting to maximize the reproducibility and translational potential of research. Read Less

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

This study will apply low-intensity transcranial focused ultrasound to dorsal root ganglia in patients with chronic neuropathic pain. The target will be validated using magnetic resonance imaging. The stimulation will first be delivered using a range of stimulation parameters during psychophysical and physiological monitoring. A well-tolerated stimulation protocol will be selected for subsequent testing in a blinded randomized sham-controlled cross-over trial. The level of pain will be evaluated using the Numerical Rating Scale (NSR-11) and the Patient-Reported Outcomes Measurement Information System (PROMIS) numerical rating scales of pain. Read Less

The purpose of this study is to determine if playing a virtual reality walking game can help improve neuropathic pain in adults with incomplete spinal cord injury. Read Less

Doctors sometimes treat chronic pain with devices that send mild electrical currents into the spinal cord. This type of treatment is referred to as neurostimulation. A common form of neurostimulation therapy is spinal cord stimulation (SCS). In this study, researchers want to learn more about how SCS affects pain processing and relieves pain. The researchers will examine multiple forms of SCS in chronic pain patients who are receiving SCS from their own doctors as part of their standard of care. During the study, participants will be asked to complete a variety of evaluations at certain time points. Read Less

The purpose of the second part of the study is to examine the effect of reflex training in the leg to decrease neuropathic pain. For this, the researchers are recruiting 15 individuals with neuropathic pain due to spinal cord injury to participate in the reflex training procedure. The study involves approximately 50 visits with a total study duration of about 6.5 months (3 months for baseline and training phases followed by 1 month and 3 month follow-up visits). Read Less

Patients experience pain after their knee replacement surgery - and some may continue to experience persistent pain long after their knee replacement surgery. Traditional pain management strategies reply on pain medication such as opioids for pain control. However, these drugs do not work well for pain associated with movement or the the nerve pain (tingling, electrical sensations) after surgery. In addition, opioids are associated with significant side effects such as nausea, vomiting, respiratory depression, depression, cognitive dysfunction and risk of persistent opioid use. Neuropathic pain medications, such as venlafaxine are effective in managing nerve pain. Recent studies also support its potential role in acute pain management. Here, we propose a prospective randomized clinical trial 1) to evaluate the efficacy of Venlafaxine in reducing pain intensity and opioid consumption at post-operative day 1 (POD1) and 1- week after surgery, and 2) to examine whether the use of Venlafaxine will reduce the incidents of chronic postsurgical pain in TKA patients at 3-month time point.

Spinal cord injury (SCI) is associated with severe neuropathic pain that is often refractory to pharmacological intervention. Preliminary data suggest brivaracetam is a mechanism-based pharmacological intervention for neuropathic pain in SCI. Based on this and other reports in the literature, SCI-related neuropathic pain is hypothesized to occur largely because of upregulation of synaptic vesicle protein 2A (SV2A) within the substantia gelatinosa of the injured spinal cord. Furthermore, compared to placebo, brivaracetam treatment is hypothesized to reduce severe below-level SCI neuropathic pain and increases parietal operculum (partsOP1/OP4) connectivity strength measured by resting-state functional Magnetic Resonance Imaging (rsfMRI). Circulating miRNA-485 levels may be associated with change in pain intensity due to brivaracetam treatment. The study aims to determine the efficacy of brivaracetam treatment for SCI-related neuropathic pain. Read Less
