Active clinical trials for "Peripheral Nervous System Diseases"

Idiopathic Small Fiber Neuropathy (called SFN for short), is a condition where nerves that sense pain have become damaged, and often painful. SFN pain is common, and it can affect sleep, memory, health and overall quality of life. Pregabalin is a drug commonly used to treat painful conditions, like nerve pain. It has been available to doctors for many years, and many studies have been performed to evaluate its effectiveness. In these studies, pregabalin has been shown to be very effective in the treatment of nerve pain, with fewer side effects than many other medications currently available. The purpose of the study is to determine if pregabalin relieves pain more effectively than a pill containing no medication (called a placebo). The study will also investigate any side effects as well as the effectiveness and safety of the medication.

This study was to determine whether ranolazine was effective in the treatment of neuropathic pain in patients with coronary artery disease. Eligibility required neurological examination by the study doctor and assessment of the patient's pain. Eligible participants were randomized to receive blinded study medication for a total of 12 weeks.

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.

The purpose of this study is to determine the diagnostic accuracy of a newly developed tool (Electrochemical Skin Conductances (ESC) measurement) easy-to-perform, non-invasive, highly reproductible and not requiring specific training, to identify pediatric chemotherapy-induced-peripheral-neuropathies (CIPN). CIPN are a frequent (20 to 75% depending on the drug), early and potentially severe long-lasting and dose limiting adverse effect of treatments in immuno-hematology and cancerology. The pathophysiology, the chronology of injury (ie small then large sensory nerve fiber or vice-versa) and the age-related short/long-term impact on peripheral nerves remain largely not understood. Clinical signs of CIPN are highly heterogenous, often under-recognized and include diverse sensory symptoms and pain. Persistent loss of sensation and strength as well as neuropathic pain may have a short/long-term impact in term of functional limitations and quality of life. There is a lack of specific and sensitive measurement tools for CIPN in the pediatric population. Neurophysiological tools (except electro-neuro-myography allowing only the assessment of large myelinated nerves) are not implemented in the pediatric oncology-hematology everyday practice: they are often invasive and/or poorly reproducible, not accessible for "bedside" follow-up, and lacking normative values, thus often dedicated only to research. ESC may provide an early and quantitative assessment of small fiber dysfunction in children, a prerequisite for the identification of additional preventive or curative approaches in CIPN.

Evaluation of Satisfaction & Efficacy of Compression Using Surgical Gloves in Peripheral Neuropathies Due to Chemotherapy

The purpose of this study is to assess analgesic efficacy of ASP3662 relative to placebo in subjects with painful diabetic peripheral neuropathy (PDPN) as well as assess the safety and tolerability of ASP3662 relative to placebo. The analgesic effect is evaluated by measuring percent responders, change in daily worst pain score, change in average daily pain score, Patient Global Impression of Change (PGIC) and Clinical Global Impression of Change (CGIC).

The goal of this clinical research study is to compare the level of effectiveness for 2 acupuncture treatment schedules for chronic CIPN in breast cancer survivors. Researchers also want to study how patients may respond to acupuncture treatments, and how the treatments may affect quality of life, hand function, balance, and the use of drugs for neuropathy pain.

The purpose of this study is to evaluate the efficacy of pregabalin compared to placebo in reducing neuropathic pain associated with HIV neuropathy.

The concept of normality is a cornerstone in medical practice and research. As an example, in clinical chemistry, a laboratory value based on a plasma sample exceeding the +/- 1.96 x standard deviation (SD) range, referenced from normative material, is, per definition, outside the normal range (the reference interval). Obviously, a number of reasons for this deviation may exist. The sample value could reflect a "true" pathological condition but could also be caused by error, e.g., technical measurement error, drug-interaction error, random error, or reflect a value occurring in 5% of the healthy population. Conversely, a sample value in the normal range evidently does not exclude a pathological condition. The reference interval is calculated from a large number of healthy subjects sampled across age, anthropometrics, ethnicity, and gender. Normative reference intervals are certainly of help, particularly in the screening of subjects, but may be of limited value in the detailed assessment of pathophysiological processes. Also, increasing the number of analyses in a subject expands the risk of making a type I error (acquiring "false" positive results). The likelihood of one or more type I errors in the analysis of 10 different laboratory values in one subject is impressive 46% ([1 - 0.95^10] =0.46). It is well-known that multiple measurements are commonly performed in medical practice and research, but corrected significance levels are not always used.

The purpose of this study is to evaluate the safety profile of orally administered tapentadol ER dosages of 100 to 250 mg twice daily in patients with chronic, painful diabetic peripheral neuropathy (DPN) over long-term exposure of up to 1 year.
