Active clinical trials for "Neuralgia"

To be eligible for the trial, subjects must have ongoing moderate to severe neuropathic pain related to a prior course of platinum and/or taxane chemotherapy and have no clinical evidence of actively progressive disease. The trial period will comprise a Screening Period (up to 35 Days), a two-week period for the determinations of Baseline pain followed by randomization and 4-day treatment, followed by a 12-week follow up period (12 weeks total after initial treatment), and an End-of-Trial/Follow-up visit, which will occur at Week 13. This is a study to research the effects of the study drug on neuropathic pain compared placebo.

Veterans with diabetes are more likely than diabetic civilians to develop disabling chronic diabetic neuropathic pain (CDNP). Research on frontline treatments for CDNP (enhanced glycemic control, exercise, pharmacological agents), shows inconsistent outcomes and dissatisfaction among Veterans. Veterans and clinicians have shown significant interest in cannabis derivatives (THC, CBD) for neuropathic pain control, but there are no well-controlled trials guiding expectations for benefit and adverse outcomes associated with cannabis for CDNP. Because Veterans are likely to present with pain and pain-related polymorbidity significantly differing from that of civilians, a well-structured clinical trial of cannabinoids for Veterans with CDNP is vital. The present phase II study will offer the first evidence describing the potential benefits and adverse effects of cannabinoids for CDNP in Veterans using a four-arm, double-blind, multisite randomized trial comparing THC, CBD, THC+CBD and placebo on neuropathic pain outcomes.

Spinal cord stimulation (SCS) relies on stimulation of pain-relieving pathways in the spinal cord to treat chronic neuropathic pain. Traditional paresthesia-based SCS (PB-SCS) relies on providing analgesia through stimulation of spinal cord dorsal columns but it is often associated with attenuation of analgesic benefit and lack of acceptance of paresthesias. Recently introduced three different paresthesia-free (PF-SCS) modes of stimulation aim to overcome limitations of PB-SCS. Several questions regarding PB and PF SCS modes remain unanswered including the mechanisms of therapeutic benefit, criteria for selecting patients likely to benefit, and long-term outcomes. A concerted effort is required to understand and optimize utilization of SCS. This project has the twin goals of using neuroimaging techniques to understand mechanisms that underlies analgesic benefit from PB/PF-SCS modes and to identify criteria for selecting patients based on monitoring of pain and its related domains in patients undergoing SCS trials. Achieving these objectives will increase probability of analgesic benefit while minimizing adverse effects and knowledge gains from this study will be applicable to other therapies for chronic pain conditions.

The objective of the study is to a) assess the presence of a maladaptive stress response, a decreased pain modulation and any cognitive impairment in patients with chronic neuropathic pain in comparison to healthy controls. and b) evaluate the efficacy of a treatment of hypnosis and of an open label placebo on these neuro-cognitive factors and on clinical pain. This will be done through a) a prospective observational comparative study of patients (base line measures) with Healthy Controls (HC) and b) an Open label; randomised, hypnosis vs. open label placebo (OLP) vs. treatment as usual control design; with a second phase of exploratory cross-over.

Herpes zoster (HZ) is an acute herpetic skin disease caused by the reactivation of the varicella-zoster virus (VZV) latent in the sensory ganglia. Postherpetic neuralgia (PHN) often occurs after herpes zoster heals and persists for a long time. At present, clinically anticonvulsants (such as gabapentin, pregabalin) and antidepressants (such as amitriptyline) are clinically first-line drugs for the treatment of PHN, which are not usually effective to treat PHN well, as well as to alleviate patients' bad mental symptoms. Esketamine, as a well-known N-methyl-D-aspartate receptor inhibitor, has both analgesic and antidepressant effects with extremely few incidence of respiratory depression, delirium, hallucinations, nausea and vomiting. Therefore, we hypothesize that esketamine could relieve PHN and Anxiety and depression-like symptoms symptoms in patients with PHN. This study intended to compare the efficacy of pregabalin, amitriptyline combined with esketamine therapy and pregabalin combined with amitriptyline therapy for alleviating PHN, and to further explore the feasibility and safety of esketamine in the treatment of PHN as well as underlying the mechanism of esketamine on the PHN.

This is a double-blind randomised controlled trial (RCT) which compares the effectiveness of three surgical techniques for alleviating residual limb pain (RLP), neuroma pain and phantom limb pain (PLP). The three surgical treatments are Targeted Muscles Reinnervation (TMR), Regenerative Peripheral Nerve Interface (RPNI), and an active control (neuroma excision and muscle burying). Patients will be follow-up for 4 years.

Exparel has a proven efficacy in providing pain relief for up to 72 hours with a single-dose administration at surgical sites. The study aims to evaluate the effectiveness of endoscopically-guided injection of Exparel (Bupivacaine) for the treatment of craniofacial pain. This study would be conducted in a prospective, randomized, double-blinded, placebo- controlled, and cross-over fashion. We aim to investigate whether the administration of Exparel (Bupivacaine) to the lateral nasal wall may positively impact craniofacial pain and functional outcomes, in patients who experience relief with the topical application of Lidocaine (routinely given prior to almost all ENT endoscopy).

This pilot study evaluates the tolerability and feasibility of the Axoguard Large-Diameter Nerve Cap (sizes 5-7 mm) for protecting and preserving terminated nerve endings after limb trauma or amputation when immediate attention to the nerve injuries is not possible.

The main objective of this clinical trial is to evaluate the effectiveness and cost-effectiveness of adding ozone therapy to the clinical management of patients with pain secondary to chemotherapy-induced peripheral neuropathy

The investigators designed the multicenter randomized parallel controlled clinical trial of electroacupuncture on PHN which is rigorously designed and have an appropriate sample size, aiming to evaluate the efficacy and safety of electroacupuncture in pain relieving and pain removing in the treatment of patients with PHN.
