Filter by:The purpose of this study is to determine whether impaired glucose handling (abnormality in the way the body processes blood sugar) can cause a neuropathy (damage to the nerves).
The purpose of this study is to determine whether Acetyl L-carnitine can prevent the development of nerve damage, known as neuropathy, in individuals taking anti-HIV drugs over a 48-week period. In addition the safety and tolerability of Acetyl L-carnitine will be assessed. This study compares the use of Acetyl L-carnitine or placebo (a dummy drug) in the prevention of nerve damage. The current standard of care is to use painkillers to manage the pain, with little or no effect. The possible beneficial effects of taking Acetyl L-carnitine is to prevent nerve damage as a result of anti-HIV medication. The main purposes of the trial are: - to look at the differences in between those on Acetyl L-carnitine versus those on placebo - to look at the effect on state of your nervous system in the two treatment groups by measuring nerve activity - to learn more about the safety and tolerance of Acetyl L-carnitine
The intent of this study is to demonstrate the efficacy and safety of Immune Globulin Intravenous (Human), 10% Caprylate/Chromatography Purified (IGIV-C) in newly or previously diagnosed CIDP subjects. Eight courses of treatment with either placebo or IGIV-C will occur every 3 weeks. Neurological function will be measured by Inflammatory Neuropathy Cause and Treatment (INCAT) scores. Patients who deteriorate or show no improvement between day 16 and month 6 will receive the alternate study drug for an additional 6 months.
Many people with polyneuropathy suffer from pain which is difficult to treat. Escitalopram is a relatively new drug used in the treatment of depression. Escitalopram’s action mechanism on the brain suggests that escitalopram also may have an effect on neuropathic pain. This study will test the efficacy of escitalopram in patients with painful polyneuropathy.
Considering the mechanisms of action which provide efficacy in epilepsy, it is hypothesized that treatment with levetiracetam will reduce the neuronal excitability involved in neuropathic pain associated with CIAP. Thus, there is a potential for levetiracetam to bring therapeutic benefit for the subjects because of its specific mechanism of action, its safety profile and the absence of interaction with other drugs.
Foot ulcers remain the most common reason for hospital admission among veterans with diabetes. Healing and preventing these wounds should be a high priority for clinicians treating these high-risk patients. Previous work by the investigators has suggested that diabetic foot ulcers are preceded by inflammation, which can potentially be detected with a thermometer.
This is a safety and efficacy trial of ranirestat(AS-3201) which is an aldose reductase inhibitor in patients with diabetic sensorimotor polyneuropathy.
This study is an open-label, multicenter, extension study for subjects who completed NeurogesX Study C111 and received treatment with NGX-4010 (Capsaicin Patch) within 12 weeks (up to +7days) before entry into Study C114
This study is a randomized, open-label multi-center evaluation of the tolerability of treatment with NGX-4010 in conjunction with pre-patch topical application of one of three 4% lidocaine-based local anesthetic products. Eligible subjects will have moderate to severe neuropathic pain secondary to painful diabetic neuropathy (PDN), postherpetic neuralgia (PHN) or HIV-associated neuropathy (HIV-AN), with average numeric pain rating scale (NPRS) scores during screening of 3 to 8 (inclusive).
This study will test the safety and effectiveness of the drug Rituximab in treating a nerve disease called MGUS (also known as neuropathy with anti-MAG antibodies). Patients with MGUS have an abnormal protein called monoclonal IgM immunoglobulin that attacks the myelin sheath (protective coating) of nerves, causing them to not function properly. The disease affects the nerves in the legs or arms, and patients have numbness, tingling, muscle weakness, and unsteady gait. There are no adequate treatments. Immunosuppressive drugs or human immunoglobulin infusions can produce mild and transient improvement, but the benefits of these therapies are not significant. The abnormal immunoglobulin protein in MGUS is produced by white cells called B lymphocytes. Rituximab is approved to treat B cell lymphomas. Also, the drug showed promise in a recent study of patients with demyelinating neuropathy associated with production of antibodies from B lymphocytes directed against certain nerve proteins. Although the number of patients treated with Rituximab was small, the drug was well tolerated and caused significant improvement in several of the patients. Patients 25 years of age and older with MGUS may be eligible for this 2-year study. Candidates will be screened with a medical history, physical and neurological examinations, and blood tests. Participants will be randomly assigned to receive intravenous (through a vein) infusions of either Rituximab or placebo (a solution that looks like Rituximab but has no active ingredient) once a week for 4 consecutive weeks. In addition, they will undergo the following tests and procedures: - Monthly follow-up visits following Rituximab treatment for repeat physical and neurological examinations, blood tests, muscle strength measurements, and review of signs and symptoms. - Two sessions of lymphapheresis, one at the beginning of the study and one a year later-to collect lymphocytes. For this procedure, whole blood is drawn through a needle in an arm vein, much like donating a unit of blood. The blood then flows through a catheter (plastic tube) into a cell separating machine, where the white blood cells are extracted and removed. The red cells and plasma are then returned to the body through a needle in the other arm. The procedure takes about 60 to 90 minutes. - Electrophysiologic studies (electromyography and nerve conduction testing) are done once at the beginning of the study and again one year later. For electromyography, a small needle is inserted into a few muscles and the patient is asked to relax or to contract the muscles. The electrical activity of the muscle cells is recorded and analyzed by a computer. For nerve conduction testing, nerves are stimulated through small wire electrodes attached to the skin and the response is recorded and analyzed. If this study indicates that Rituximab is beneficial against MGUS, patients who were assigned to receive placebo during the trial will be offered treatment with Rituximab (four weekly infusions) at the end of the study.
