Active clinical trials for "Polyneuropathies"

Polyneuropathy of different etiologies is often associated with pain. The standard treatment of this pain is anticonvulsants or antidepressants, but none of these treatment are effective or tolerable for all patients. Levetiracetam is a newer anticonvulsant and it is the hypothesis is that it could relieve neuropathic pain in polyneuropathy. This is a randomised, double-blind, placebo-controlled, cross-over trial on the effect of levetiracetam 3.000 mg/day on pain in polyneuropathy

This study will compare the efficacy and the safety of ABT-894 (1mg, 2mg or 4mg capsules) administered BID to placebo in the treatment of DNP. Another treatment arm will be Duloxetine 60mg administered once daily (QD). Approximately 275 subjects will be enrolled into the study at approximately 50 sites in both the United States and Europe. The study will be divided into the following periods: Screening/Washout (21 days) followed by a Baseline Visit, an 8-week Treatment Period and a 1-week Follow-up Visit.

This is a safety and efficacy trial of ranirestat(AS-3201) which is an aldose reductase inhibitor in patients with diabetic sensorimotor polyneuropathy.

This is a single-arm, open-label, multicenter study designed to determine the effect of tafamidis meglumine on TTR stabilization as well as tafamidis meglumine safety, tolerability and efficacy in ATTR-PN patients in China. Approximately 10-15 participants are planned to be enrolled. All enrolled participants will receive oral tafamidis meglumine 20 mg soft capsules once daily for 72 weeks (18 months).

Investigators propose a placebo controlled, double blinded study to examine efficacy of topical Gelnique 3%TM (3% oxybutynin) daily for 20 weeks) in improving IENF density in type 2 diabetic subjects with established peripheral neuropathy. This site most clearly demonstrated efficacy of topiramate in reversing IENF loss within 18 weeks in our prior study. Subjects will also undergo quantitative sensory testing (QST) and assays of laser Doppler skin blood flow (SkBF), neuropathy total symptom score (NTSS-6), and quality of life (Norfolk QOL-DN), along with standard measures of physiology and fasting blood chemistry. Subjects with IENF loss of between 20-75% of normative values and thus amenable to therapy-induced recovery, will be randomized into placebo (N=30) or active drug (N=30) arms and instructed in how to apply 84 mg Gelnique 3%TM or hydrogel placebo to cover a 2 in2 region of skin adjacent to the initial biopsy site, as per the manufacturers instructions (http://www.gelnique.com/gel3/). Treatment will continue daily for 20 weeks, with monthly phone calls to monitor compliance. After 20 weeks, subjects will return for a second series of measurements and 3 mm skin biopsy from the treated region of skin.

The purpose of this study is to evaluate the efficacy and safety of inotersen given for 65 weeks in participants with Familial Amyloid Polyneuropathy (FAP).

Patients diagnosed with Chronic Inflammatory Demyelinating Polyneuropathy were confirmed based on the European Federation of Neurological Societies/ Peripheral. Nerve Society Guideline. Patients who meet all inclusion criteria and do not conflict with the exclusion criteria will receive NPB-01 (intravenous immunoglobulin) 400mg/kg/day for five consecutive days. Subsequently, patients receive NPB-01 1g/kg every 3weeks and evaluate the Inflammatory Neuropathy Cause and Treatment（INCAT） score and INCAT sensory sumscore（ISS） et al. As a safety endpoint, the safety of NPB-01 will be investigated the occurrence of adverse events by one year after the start of the study treatment.

The purpose of this large comparative effectiveness study led by Richard J. Barohn, MD, of the University of Kansas Medical Center, is to learn about the safety and effectiveness of nortriptyline, duloxetine, pregabalin and mexiletine in treating cryptogenic sensory polyneuropathy (CSPN).

The objective of this study is to demonstrate the efficacy and safety of Privigen in subjects with CIDP.

The purpose of the study is to evaluate the clinical effects of the investigational drug, SB-509, in subjects with diabetic neuropathy.
