Filter by:The purpose of this trial is to determine if the effect of oxcarbazepine on chronic peripheral nerve pain depends on the supposed mechanism of the pain, ie. if oxcarbazepine mainly relieve pain in patients with irritable nerves.
This is a prospective, randomized, double blind, comparative, experimental controlled Phase 3 clinical trial to assess the efficacy, safety and superiority of F0343 (gabapentin combined with B vitamins) compared to gabapentin alone for treating neuropathic pain in subjects with chronic distal diabetic polyneuropathy.
The cross sectional area of posterior tibial nerve (PTN) is increased in diabetic patients with distal symmetric polyneuropathy (DSPN) as compared to diabetic patients without DSPN. This study aims to evaluate whether the cross sectional area of the Posterior Tibial Nerve (PTN) as measured by ultrasound is increased in patients with distal symmetric polyneuropathy (DSPN) as compared to diabetic patients without DSPN.
Pain due to peripheral nerve lesion remains extremely difficult to treat and current treatments have onl moderate efficacy and/or side effects. The investigators have previously demonstrated the long term efficacy of Botulinum toxin type A (BTX-A) in a small group of patients with post-traumatic/postherpetic neuralgia and allodynia. The present study aims to a/ confirm the efficacy of repeated applications of BTX-A in a larger group of patients with peripheral neuropathic pain with or without allodynia(primary outcome) ; b/ evaluate its mechanisms of action ; c/analyse the predictors of response ;d/analyse whether the second injection is associated with a therapeutic gain. This will be a randomized placebo controlled study. A total of 30 patients will be randomized to receive either BTX-A (subcutaneous injection in the painful area) or placebo. Each injection will be repeated within at least 3 months depending on the duration of efficacy. Skin punch biopsies will be performed before and 1 month after BTX-A administration. The investigators postulate that this study will confirm the clinical efficacy and good safety of repeated administrations of BTX-A in the treatment of peripheral neuropathic pain.
The primary endpoint of this study is to determine what percentage of patients receiving high-dose Cyclophosphamide may experience a halt in the worsening of their disease or experience improvement of their disease and for how long the benefit may last.
The purpose of the study is to evaluate the efficacy on overall neuropathic sensory symptom improvement of Thioctacid tablet 600mg once daily vs. placebo in 6-weeks' treatment in Chinese diabetic patients with distal symmetric polyneuropathy (DSP).
The objective of this study is to demonstrate the efficacy and safety of Privigen in subjects with CIDP.
The purpose of this study is to evaluate the efficacy of the NormaTec PCD, a non-invasive pneumatic compression device with the patented peristaltic pulse pneumatic waveform, in the treatment of Diabetic Peripheral Neuropathy (DPN). The study will compare treatment with a NormaTec PCD and a sham device to assess whether the NormaTec PCD improves the signs and symptoms of DPN.
Rationale: Diabetic neuropathy is one of the most common complications of Diabetes Mellitus (DM). Pain is a common symptom of diabetic neuropathy, affecting 11-34% of patients suffering form DM. The burden of disease of painful diabetic polyneuropathy (PDP) is high for both the patient and society, due to significant pain levels, frequent co-morbidity, polypharmacy and significant health resource use. Spinal cord stimulation (SCS) has been used for over 30 years to treat neuropathic pain. Several small clinical studies have shown a beneficial effect of SCS on pain in PDP. Objective: The primary objective of this study is to investigate whether SCS leads to clinically relevant (≥50%) pain relief in patients with moderate-to-severe PDP in the lower limbs after 6 months of treatment. Secondary objectives to investigate 1) the effect of SCS on health related quality of life in PDP; 2) the effect of SCS on the quality of sleep in PDP; 3) the effect of SCS on mood in PDP; 4) the effect of SCS on blood glucose control in PDP; 5) the effect of SCS on large and small nerve fibre functions in PDP; 6) identifying predictive factors for success of SCS treatment of PDP; after 6 months 7) the effect of SCS on small fibre loss and regeneration in PDP; and 8) costs, cost-utility and cost-effectiveness after 12 months of treatment. Study design: the study is a multi centre randomized controlled trial. Study population: Patients suffering from moderate-to-severe PDP in the lower limbs due to diabetes mellitus type 1 or type 2 as diagnosed by clinical symptoms (glove and stocking distribution). Intervention: patients assigned to group 1 will receive spinal cord stimulation (SCS) and/or best (drug) treatment as possible, patients assigned to group 2 will receive best (drug) treatment as possible. Main study parameters/endpoints: The main study parameter will be the mean pain intensity and/or maximal pain intensity during daytime and/or during night time as measured on a weighted NRS and/or a PGIC for pain and sleep measured on a 7-point Likert scale, after 6 months of treatment. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: SCS related risks include: lead migration (14%), lead breakage (7%), implanted pulse generator migration (1%), loss of therapeutic effect, lost or unpleasant paresthesias (12%), infection or wound breakdown (10%), Pain at IPG incision site (12%), IPG pocket fluid collection (5%). Treatment-as-usual related risks are related to the medication used and do not increase due to participation in this study.
Tramadol is an opioid analgesic, which is widely used in the treatment of acute and neuropathic pain. Treatment of neuropathic pain often requires a combination of pain medications due to the complex nature of neuropathic pain and frequent inadequate response to drug treatment. Common drugs used concomitantly with tramadol are SNRI antidepressant duloxetine and anticonvulsants such as pregabalin. Both tramadol and duloxetine have serotonergic effects and duloxetine has also a potential to inhibit metabolism of tramadol. The objective of the study is to investigate the pharmacokinetics and pharmacodynamic interaction of oral tramadol with duloxetine and pregabalin in patients with chronic neuropathic pain due to postherpetic neuralgia or diabetic polyneuropathy. All subjects will receive tramadol and duloxetine or tramadol and pregabalin in a randomized double-blind order. Primary end point is O-desmethyltramadol concentration.
