Effects of PR Oxycodone and of Levodopa, vs Placebo, on Central Neuropathic Pain in Parkinson's...
Parkinson DiseaseThis study will be conducted in three parallel groups receiving oxycodone, levodopa or placebo, administered as an add-on therapy, in addition to the usual antiparkinsonian treatment. As this study focuses on chronic central neuropathic pain caused by PD, the effects of study treatments will be evaluated after a 10-week treatment period
Efficacy and Safety of Pregabalin in Treatment of Neuropathic Pain in Patients With Idiopathic Small...
Idiopathic Small Fiber NeuropathyThe purpose of this study is to assess safety and efficacy of treatment with pregabalin in patients with idiopathic small fiber neuropathy proven by skin biopsy.This is an enriched enrollment randomized withdrawal study that comprises 4 phases: a screening and selection phase, a washout period from previous pain medication for enriched enrollment, an 8 week single blind pregabalin treatment phase; and a 4 week randomized withdrawal phase.
DS-5565 Phase III Study for Renal Impairment in Japanese Subjects
Diabetic Peripheral Neuropathic PainPost-herpetic NeuralgiaInvestigate the safety and efficacy of DS-5565 in Japanese subjects with Diabetic Peripheral Neuropathic Pain (DPNP) with renal impairment or Post-Herpetic Neuralgia (PHN) with renal impairment.
Brain-Train Home Based Pain Treatment
Neuropathic PainA study examining the effectiveness of neurofeedback therapy for the treatment of Central Neuropathic Pain (CNP), in patients with a Spinal Cord Injury, using a small user-friendly device which can be operated by patients at home.
A Comparative Study of FV-100 vs. Valacyclovir for the Prevention of Post-Herpetic Neuralgia
ShinglesHerpes Zoster1 moreThis is a multicenter, randomized, double-blind, parallel-group, active controlled comparative study of the safety and efficacy of 2 dosing regimens of FV-100 versus valacyclovir administered for 7 days in subjects with uncomplicated AHZ(acute herpes zoster).
Trial of Dronabinol and Vaporized Cannabis in Chronic Low Back Pain
CannabisLow Back Pain1 moreThis study will involve treating low back pain associated with nerve injury with oral delta-9-tetrahydrocannabinol (Δ9-THC) or whole plant cannabis for eight weeks. Research subjects will consume either oral Δ9-THC (dronabinol), vaporized 3.7% Δ9-THC/5.6% CBD, or placebo. An analysis will then be determined to assess the risk--benefit ratio of dronabinol and vaporized 3.7% Δ9-THC/5.6% CBD .
Mannitol Cream for Post Herpetic Neuralgia
NeuralgiaPostherpetic30% mannitol cream has shown its ability to reduce the activation of the Capsaicin (TRPV1) (Transient Receptor Potential Vanilloid 1) receptor, a likely cause of the pain of post-herpetic neuralgia (PHN). This randomized placebo-controlled crossover study compares PHN pain one week before, for one week on the randomly assigned mannitol versus placebo cream and, after a three day washout, for one week on the other cream. Following this crossover study, participants receive mannitol cream for three months. Pain levels will be checked to assess whether continued use of this cream significantly reduces the pain levels associated with PHN. If pain persists beyond 3 months, participants will be offered mannitol and menthol cream for one month following which their pain levels will be checked.
Cyclization of Motor Cortex Stimulation
Neuropathic PainMotor cortex stimulation (MCS) is a form of brain stimulation for patients with neuropathic pain not responsive to medication. An electrode is placed on the surface of the brain and connected to a programmable battery in the chest. The strength of stimulation can be individually adjusted by changing the voltage of stimulation. A too high voltage will produce side effects (e.g. seizures) while a too low voltage will not provide pain control. The aim of this study is to analyze the optimal stimulation timing parameters in patients already implanted with MCS and have received good pain relief. The investigators wish to cyclize on/off MCS in order to save the battery life of the stimulator and also decrease stimulus habituation. The investigators hope to determine these timing parameters while maintaining optimal pain relief.
'Fix the Dysfunction' Concept for Mechanism-based Pharmacological Treatment of Neuropathic Pain...
Neuropathic PainIntroduction Treatment of neuropathic pain has been a goal of numerous research projects for the last half century, with overall disappointing results. These poor achievements are in contrast with substantial advancements in the understanding of pain mechanisms, and numerous molecules developed to tackle them. The need to better identify patients likely to respond to treatment comes from the neuropathic pain experts in regards to the pharmacological domain. The basic assertion of this project is that the pain modulation profile is altered in pain patients toward a pro-nociceptive mode, and that the specific single or multiple dysfunctions of pain modulation that underlie this pro-nociceptivity should be targeted by therapeutic lines that can reverse the modulation back toward eu-nociceptivity. The aim of this amendment is to demonstrate that pain treatment efficacy for painful diabetic neuropathy can be optimized by individualizing pharmacological treatment choice along 'fix the dysfunction' concept
TENS Trial to Prevent Neuropathic Pain in SCI
Spinal Cord InjuriesThe purpose of this research study is to: 1) test whether transcutaneous electrical nerve stimulation (TENS) after spinal cord injury can reduce the onset of post-injury neuropathic pain; and 2) to learn more about this kind of pain and who is at risk for suffering from this type of pain after spinal cord injury. Neuropathic pain is a type of pain that occurs in about 50% of people with spinal cord injury. This type of pain is usually described as "burning" or "tingling," and is present around the level of injury and/or in areas below the level of injury. The investigators' goal is to try a non-drug treatment (TENS) that may help prevent this pain from occurring. Pain symptoms will be compared between the study participants who receive active TENS and the study participants who receive a sham TENS treatment.
