Active clinical trials for "Neuralgia"

The purpose of this Study is to test the Safety and Effectiveness of MK0686 in relieving neuropathic (chronic) pain as experienced by patients with Postherpetic Neuralgia (Also Know as PHN or Post Shingles Pain). This is an early phase trial and some specific protocol information is proprietary and not publicly available at this time. (Full information is available to trial participants).

This study is to evaluate the long-term efficacy and safety of two dosages of bicifadine SR (600 mg/day and 1200 mg/day) for up to 52 weeks in reducing chronic peripheral neuropathy pain due to diabetes in adult outpatients.

EAA-090 is being developed for the treatment of neuropathic pain associated with diabetic neuropathy. It is a selective antagonist that binds competitively to the glutamate site of the N-methyl-D-aspartate (NMDA) receptor. This study will assess the safety and efficacy of 3 fixed oral doses of EAA-090 compared with placebo in subjects with neuropathic pain associated with diabetic neuropathy.

A randomized, blinded, placebo-controlled study assessing the impact of health and wellness products on pain and other health outcomes

Alpha 2 macroglobulin (A2M) is a plasma protein that acts as a molecular trap for inflammatory factors such as tumor necrosis factor (TNF). After plasma is enriched for A2M, it may be injected for treating chronic inflammation. Plasma enriched for A2M may be considered as a possible injectable agent to counteract inflammation that may occur with a cervicobrachial pain syndrome. This study reports on an experiencing using A2M to treat cervicobrachial syndrome which was predominant for either musculotendinous or neuralgic features.

Prospective multicentric observational trial on caregiver burden, caregiver satisfaction and clinical outcome in spinal cord stimulation for chronic neuropathic pain.

Transcranial Direct Current Stimulation (tDCS) is a noninvasive brain stimulation technique that utilizes low amplitude direct currents applied via scalp electrodes to apply currents to the brain and modulate the level of cortical excitability. tDCS applied over the dorsolateral prefrontal and motor cortex has been reported to be able to decrease pain sensation and to increase pain threshold in healthy subjects and is effective in reducing central chronic pain in patients with multiple sclerosis (PwMS.) In spite of the encouraging results of tDCS in PwMS, detailed mechanisms accounting for its analgesic effect have not yet been elucidated. This will be the first study to determine the effects of tDCS on whole and regional brain activity in PwMS with neuropathic pain to identify potential mechanisms of the analgesic effects of tDCS. These findings will provide targets for future studies investigating different stimulation areas, possible short- and long-term side effects, and specific target areas for other precise stimulation techniques such as transcranial magnetic stimulation.

Loxapine is an antipsychotic drug approved for the treatment of schizophrenia in several countries including the United States. In animal studies in mice, loxapine reduced neuropathic pain. Hence, in a proof-of-principle and dose-escalating study the tolerability and analgesic efficacy of loxapine will be evaluated in patients with neuropathic pain.

Trigeminal neuralgia or tic douloureux is severe, often debilitating, facial pain that significantly impairs the patient's quality of life and health. Stereotactic radiosurgery has been shown to provide pain relief in majority of patients treated. However, a common side effect of radiosurgery is facial numbness. Our goal is to maximize pain control while minimizing side effects. To this end, the purpose of this study is to evaluate whether adding a drug, amifostine, at the time of radiosurgery will protect patients from facial numbness.

The purpose of this trial is to determine if patients suffering from diabetic peripheral neuropathic pain treated with ranolazine will have a greater reduction in pain compared to placebo. Hypothesis: From the prior clinical observations, and analgesic efficacy in the preclinical animal model of neuropathic pain, the investigators hypothesize that subjects randomized to ranolazine will show a greater reduction in diabetic neuropathic pain compared to placebo.
