Active clinical trials for "Polyneuropathies"

The purpose of this study is to determine whether botulinum toxin A is effective in the treatment of neuropathic pain in patients with diabetic peripheral polyneuropathy.

The goal of the present study is to determine the occurrence of wild-type and hereditary transthyretin amyloidosis cardiomyopathy among patients with the diagnosis of idiopathic peripheral neuropathy in the setting of a state-of-the-art diagnostic work-up; the investigators believe that the identification of patients with ATTR-CM in this setting can contribute to the early diagnosis of a largely underrecognized condition and, therefore, offer conditions to timely initiation of appropriate therapy with impact on prognosis of patients.

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

Chemotherapy-induced peripheral neuropathy (CIPN) is a highly prevalent and clinically relevant side-effect of cancer treatment. The severe symptoms such as loss of sensation, numbness, pain, absent reflexes or loss of balance control not only diminish children's quality of life but also affect the medical therapy. To date, there are no effective treatment options to reduce the symptoms of CIPN. Promising results have so far been achieved with specific exercise interventions. The investigators would therefore like to conduct a prospective, multicenter, two-armed trial (RCT with follow-up). Patients (N=20) will be recruited from the Hospital for Children and Adolescents, Kantonsspital Aarau. Prior to randomization, all primarily eligible patients that have received a platin derivate or vinca-alkaloid, will be screened for symptoms of CIPN. Eligible patients with a neurologically confirmed CIPN will then be randomized either into an intervention group or a control group (CG). Patients in the intervention group will perform a standardized, age-adjusted, specific playful sensorimotor training (SMT) program twice a week for 12 weeks in addition to usual care, while the control group receives treatment as usual. The CG will be given the opportunity to participate in the intervention after study completion. Data change will be assessed at 3 time points: At baseline (T0), after 12 weeks (post intervention testing, T1), and after 12 weeks of follow-up (T2). Primary endpoint is the Ped-mTNS score in order to subjectively as well as objectively assess the severity of CIPN symptoms. It contains a short questionnaire as well as more objective parameters such as light touch sensation, pin sensibility, vibration sensibility, deep tendon reflexes and muscular strength. Additionally, the CIPN symptom pattern will be assessed via nerve conduction studies, CIPN related pain, dorsiflexion and knee extension as well as postural control. Furthermore, investigators will be evaluating patients' level of physical activity, walk to run transition time, lower limb power as well as patients integration in physical education (PE) in school and sport club activities. The investigators hypothesize that patients in the intervention group will be able to reduce relevant symptoms of CIPN, improving related physical functions and enhancing children's social reintegration.

Biomarkers for prognosis of patients with polyneuropathy.

The purpose of this study was to evaluate the safety and effectiveness of revusiran (ALN-TTRSC) in adults with transthyretin-mediated amyloidosis (ATTR), whose disease has continued to worsen after liver transplantation. Dosing has been discontinued; patients are being followed-up for safety.

One of the most common complications of diabetes mellitus is diabetic polyneuropathy, which leads to disability and reduces quality of life. The toxic effects of high glucose concentrations contribute to the formation of ketoaldehyde free radicals, which, at an increased rate of their formation, leads to the development of oxidative stress in the nervous tissue. The planned study of the use of Cytoflavin® in diabetic polyneuropathy is substantiated by its antioxidant effect, which, by analogy with alpha-lipoic acid preparations, suggests its efficacy in the combined treatment of such patients. This clinical study is being conducted to assess the efficacy and safety of Cytoflavin® versus Placebo in diabetic polyneuropathy patients with type 2 diabetes. Study patients will receive study medication, 10 IV infusions followed by 75 days of oral intake. Clinical efficacy will be assessed by alleviation of symptoms (burning, numbness, pain and pricking), using the total symptoms score(TSS), after the completion of the treatment course.

Objectives: The main objective is to evaluate the efficacy and safety of phenytoin cream in patients with neuropathic pain due to chronic idiopathic axonal polyneuropathy (CIAP). The second objective is to determine the predictive value of a double-blind placebo-controlled response test (DOBRET) to identify sustained responders. Study design: This is a 6-week enrichment randomized double-blind, placebo-controlled cross-over trial evaluating phenytoin cream in 84 participants with painful CIAP, whereafter an open label extension phase is offered with phenytoin 20 percent cream for up to one year. At baseline a DOBRET with phenytoin 10 percent and placebo cream will be performed in each study participant to stratify participants according to their response to the DOBRET before entering the double-blind cross-over phase. DOBRET positive participants are those who experience at least two points pain reduction on the 11-point numerical rating scale (NRS) on the phenytoin 10 percent cream applied area within 30 minutes and at least one-point difference in pain reduction on the NRS between phenytoin 10 percent and placebo cream applied area, in favour of the former. Participants will receive three treatments in a double blind fashion and in a randomized order: phenytoin 10 percent, phenytoin 20 percent and placebo cream. The duration of each treatment period is two weeks. Participants will cross-over two times to each of the other treatments. The study does not have wash-out periods between treatments, because the mean duration of analgesic effect after an application is expected to be less than nine hours. A blood sample will be collected at the end of the second week of the first treatment period to test for phenytoin plasma levels. Study population: The investigators aim to include 84 participants, age 40 years or older, who have been diagnoses with painful CIAP at the University Medical Center Utrecht and fulfil the inclusion criteria and have given written informed consent. Interventions: Phenytoin cream in concentrations of 10 percent and 20 percent cream compared to placebo cream. Primary endpoint: Change in pain intensity measured on the NRS between baseline and week 2 for phenytoin 20% cream versus placebo cream.

The purpose of the study is to determine whether phyllanthus niruri and sida cordifolia are effective in treatment of diabetic polyneuropathy compared to placebo. Also two different administration forms (extract capsules and crude herbs) are used to find out whether there are differences in efficiency and compliance.

To describe if there are differences in the subjective, objective and electrophysiologic parameters of diabetic polyneuropathies at baseline, four (4) weeks, eight (8) weeks, and twelve (12) weeks after Cilostazol therapy.
