View clinical trials related to Postherpetic Neuralgia.
Filter by:Postherpetic Neuralgia is a painful nerve condition that can occur when nerve fibers are damaged following an outbreak of shingles. The purpose of this study is to identify and study abnormalities in the nerves and cells in the of patients with postherpetic Neuralgia (PHN) and characterize changes that could be responsible for causing nerve pain. This data will be compared to the tissue of healthy volunteers. Our goal is that this information will lead to the development of better treatment options for people with painful nerve conditions.
This is a Phase 2 randomized, double-blind, placebo-controlled, multiple-dose, multicenter, parallel-group study to evaluate the analgesic activity of ATx08-001, a novel selective peroxisome proliferator-activated receptor modulator (SPPARM), in subjects with moderate-to-severe postherpetic neuralgia pain. Eligible subjects will be randomized to receive either placebo or Atx08-001. Study drug will be administered orally twice a day for 7 days. Subjects will be evaluated for neuropathic pain intensity at regular intervals over a 6 hour period on Day 1 following the first dose of study drug. They will then be discharged from the clinic and will complete diary assessments of pain severity twice a day at home. Subjects will be asked to return to the clinic on Day 8 to complete their last set of pain evaluations.
The purpose of this trial is to determine if the effect of oxcarbazepine on chronic peripheral nerve pain depends on the supposed mechanism of the pain, ie. if oxcarbazepine mainly relieve pain in patients with irritable nerves.
Pain due to peripheral nerve lesion remains extremely difficult to treat and current treatments have onl moderate efficacy and/or side effects. The investigators have previously demonstrated the long term efficacy of Botulinum toxin type A (BTX-A) in a small group of patients with post-traumatic/postherpetic neuralgia and allodynia. The present study aims to a/ confirm the efficacy of repeated applications of BTX-A in a larger group of patients with peripheral neuropathic pain with or without allodynia(primary outcome) ; b/ evaluate its mechanisms of action ; c/analyse the predictors of response ;d/analyse whether the second injection is associated with a therapeutic gain. This will be a randomized placebo controlled study. A total of 30 patients will be randomized to receive either BTX-A (subcutaneous injection in the painful area) or placebo. Each injection will be repeated within at least 3 months depending on the duration of efficacy. Skin punch biopsies will be performed before and 1 month after BTX-A administration. The investigators postulate that this study will confirm the clinical efficacy and good safety of repeated administrations of BTX-A in the treatment of peripheral neuropathic pain.
The purpose of this study is to assess the efficacy, safety and tolerability of NGX-1998 applied for 5 minutes for the treatment of postherpetic neuralgia (PHN).
The purpose of this trial is to determine if XPF-002 is safe and effective for the treatment of pain in subjects with Postherpetic Neuralgia
The purpose of this study is to investigate the efficacy and safety of tapentadol extended-release (ER) tablets in Japanese participants with moderate to severe chronic (lasting a long time) pain due to painful diabetic peripheral neuropathy (pain in the extremities related to diabetes-induced nerve damage) or postherpetic neuralgia (pain lasting after condition has healed).
The purpose of this study is to determine whether KAI-1678 is effective in the treatment of postherpetic neuralgia pain
The purpose of this study is to evaluate the efficacy and safety of fentanyl in opioid-naive participants with post-herpetic neuralgia, complex regional pain syndrome or post-operative pain syndrome who cannot obtain a sufficient analgesic effect by the treatment of non-opioid analgesics (drug used to control pain).
The primary objective of the study is to assess the efficacy of eslicarbazepine acetate (ESL) as therapy for patients with post-herpetic neuralgia.
