Filter by:The purpose of the study is to determine the effect of oxytocin given into the spinal fluid on pain and areas and intensity of hyperalgesia and allodynia in patients with chronic neuropathic pain.
This study will examine the efficacy of Botulinum Toxin Type A ("Botox") in treating Allodynic-type neuropathic pain in people with spinal cord injury or multiple sclerosis. Neuropathic pain is pain initiated or caused by injury to or disease of the nervous system, and is common in spinal cord injury patients or people with multiple sclerosis. Allodynia is a type of neuropathic pain caused by something that normally would not cause pain, such as light touch, pressure from clothing, or bed sheets brushing against the skin. Botox has been used to treat the muscle overactivity that causes spasticity in spinal cord injured patients. It has been noticed to exert some analgesic(pain relieving) effect, and has recently been studied as a treatment for neuropathic pain. We want to see if Botox, injected intradermally, will relieve the symptoms of allodynic-type neuropathic pain. 24 volunteers are to be enrolled, with 16 receiving active treatment, and 8 "controls" receiving placebo.
Based on laboratory studies, donepezil will improve pain relief more than placebo in patients with chronic neuropathic pain who are currently taking gabapentin or pregabalin.
Chemotherapy-induced peripheral neuropathy (CIPN) is a major dose-limiting side effect of many chemotherapeutic agents including vincristine, paclitaxel, cisplatin, oxaliplatin, bortezomib and ixabepilone. Chemotherapy-induced peripheral neuropathy commonly occurs in greater than 40% of patients. To improve the peripheral neuropathy, the chemotherapy dosing is often either decreased or discontinued potentially affecting tumor responsiveness, prognosis, and survival. There is an unmet medical need for treatment of cancer patients with chemotherapy induced neuropathic pain (CINP) and the proposed study will investigate the efficacy and safety of multiple dose levels of tetrodotoxin (TTX) versus placebo in moderate to severe neuropathic pain caused by chemotherapy.
The purpose of this trial is to investigate the efficacy and safety of lidocaine 5% medicated plaster in localized chronic post-operative neuropathic pain in comparison to placebo plaster.
This study examines the safety of pregabalin over a 6 month period in patients with neuropathic pain associated with HIV infection as an extension of another trial that tests the efficacy of pregabalin.
The main objective of the study is to evaluate the effectiveness, tolerability, and safety of tapentadol hydrochloride prolonged release in subjects suffering from severe chronic low back pain (LBP) who are taking WHO Step III analgesics and show lack of tolerability. This is a clinical effectiveness trial designed to establish a link between anticipated clinical outcomes and the clinical practice by means of selected measures of clinical and subject-reported outcome. The trial will compare the effectiveness of previous analgesic treatment (WHO Step III) with that of tapentadol hydrochloride prolonged release treatment during defined periods of evaluation.
The primary aim of this study is to investigate if AZD1386 is efficacious as an analgesic in patients with peripheral neuropathic pain. This will be done by comparing the effect of AZD1386 to placebo ("inactive substance") on pain.
This study is being conducted to assess the effects of GSK1014802 and a positive control, lidocaine, on tests of peripheral nerve excitability. This will be a double blind, placebo controlled, 4-period cross over study. Approximately 20 subjects will be randomised to one of two doses of a GSK1014802, lidocaine and placebo with at least 2 weeks between sessions. A follow-up will occur 7-15 days after the last dose. During treatment session 3 on the 6th October 2009, one subject had a pattern of AEs of severe intensity, suggestive of brain stem toxicity / encephalopathy during the lidocaine/saline infusion period. Although recognised in the literature when lidocaine was used in patients for treatment of pain, these AEs were unusual in studies in healthy subjects. The study was suspended to allow re-evaluation of the risk:benefit balance of lidocaine/saline infusion in healthy subjects in this study. It was decided that continuation of the use of lidocaine (positive control) would risk the safety of subjects. Continuation without the positive control was not possible as it would compromise the scientific integrity of the design.
The purpose of this study is to investigate if 28 days of treatment with AZD2066 compared to placebo can relieve the pain arising from the nervous system when the patients are touched by something that should not cause pain or have severe pain when they are touched by something that should only cause a little pain.
