Active clinical trials for "Neuralgia"

This study will compare Z160 and placebo in patients with Postherpetic Neuralgia for safety and efficacy for a period of 6 weeks.

The broad aim of the study is to implement and evaluate the efficacy of Graded Exposure Treatment (GET Living) to target elevated pain-related fears in children with chronic pain. Pain-related fear is an important psychological factor associated with poor outcomes in children suffering with chronic pain. To examine the efficacy of GET Living in addressing pain-related fears the investigators propose to use a sequential replicated randomized single-case experimental phase design with multiple measures. The specific aims are to 1) evaluate the effectiveness and acceptability of individually tailored GET Living for children with high pain-related fear and functional disability and 2) define anatomical and resting state connectivity patterns in the brains of children and adolescents with complex chronic pain prior to and after participation in GET Living.

This randomized, placebo-controlled, double-blind 4x4 crossover clinical trial was part of a larger NIH-funded study to evaluate the analgesic efficacy of three doses of chronic oral (PO) dextromethorphan compared to placebo in central neuropathic pain following spinal cord injury. Subjects' maximally tolerated doses (MTD) were first determined to establish individual dose-analgesic response relationships in a run-in period; following a washout period, subjects were then randomized to receive an order of four doses of dextromethorphan (including placebo) in a 4x4 Latin square cross-over design.

Recently a novel stimulation design was developed, called burst stimulation. In a non-placebo controlled pilot study burst stimulation seemed superior to tonic stimulation over a period extending more than 2 years, and even though an incidental finding, this design seemed capable of suppressing pain without mandatory induction of paresthesias. This permits for the first time to scientifically prove that spinal cord stimulation is better than placebo stimulation. A study was therefore initiated to find out whether spinal cord stimulation is indeed capable of suppressing neuropathic limb pain in a placebo controlled way.

Primary Objective: To assess the efficacy of SAR292833 versus placebo in reducing pain intensity associated with chronic peripheral neuropathic pain using 11-point numerical rating scale (NRS). Secondary Objectives: To compare the effects of SAR292833 with placebo on the change of neuropathic pain symptoms versus baseline Neuropathic Pain Symptoms Inventory (NPSI); To evaluate the effects of SAR292833 in comparison to placebo on the change in pain intensity of mechanical allodynia; To investigate the safety and tolerability of SAR292833 in comparison to placebo; To investigate the pharmacokinetics (PK) and the relationships between main efficacy parameters or pharmacodynamic effect (PD) and pharmacokinetics (PK/PD) of SAR292833 in patients with chronic peripheral neuropathic pain.

This is a phase 1, open-label, randomized, single dose, crossover clinical trial to assess the effect of food on the pharmacokinetics of YHD1119 in healthy male volunteers. Hypothesis: "YHD1119" is showing equal equal pharmacokinetics in fasted and fed state.

The aim of this study is to evaluate, versus placebo, the analgesic efficacy of the opercular-insular cortex stimulation with Transcranial Direct Current Stimulation (tDCS), in both healthy subjects and chronic neuropathic pain patients. In healthy subjects analgesia by tDCS will be assessed using both laser stimuli and cold pressor test. In patients the assessment regards their chronic pain (ratings for ongoing, evoked and paroxysmal pain, sleep and fatigue). Opercular-insular stimulation is obtained via a combined 6-electrode montage and by bi-vestibular stimulation (since vestibular pathways reach the posterior insular cortex). In patients, three separate conditions (two active and one sham) will be tested in randomised order. In healthy subjects, two other conditions are added to control for attention and distraction confounders.

This study looks at the effect of combined breathing-controlled electrical stimulation (BreEStim) and transcranial direct current stimulation (tDCS) on neuropathic pain after spinal cord injury, amputation, or brain injury. The hypothesis is that a single session of combined BreEStim and tDCS will produce an additive analgesic effect. This record covers the study in a population of healthy volunteers. Note that this study will also enroll spinal cord injury patients, brain injury patients, and amputation patients and that this study as applied to these other populations will be covered in separate ClinicalTrials.gov records.

A placebo-controlled, single-blind study to evaluate the safety and preliminary efficacy of nasal carbon dioxide for the symptomatic treatment of classical trigeminal neuralgia.

The primary objective of the study is to assess the effect of cytochrome P450 (CYP) 3A4 inhibition on the pharmacokinetics (PK) of BIIB074. The secondary objectives of this study are to assess the safety and tolerability of BIIB074 when co-administered with a strong CYP3A4 inhibitor and to assess the effect of CYP3A4 inhibition on the PK of 3 metabolites of BIIB074 (CNV3000497 [M13], CNV2283325 [M14], and CNV2288584 [M16]).
