Active clinical trials for "Peripheral Nervous System Diseases"

The purpose of the study is to evaluate the effects of stimulation parameters on clinical outcomes of Spinal Cord Stimulation (SCS) in the treatment of chronic, intractable limb pain resulting from painful Diabetic Peripheral Neuropathy (pDPN).

To evaluate the durability of efficacy and long-term safety of intramuscular (IM) administration of Engensis or Placebo that was administered in the double-blind, randomized, VMDN-003-2 Placebo-controlled Phase 3 Study.

The purpose of this clinical study is to determine the effectiveness of the Erchonia® EVRL™, manufactured by Erchonia Corporation (the Company), in providing prescription home use application for temporary relief of diabetic neuropathy foot pain in individuals diagnosed with diabetic neuropathy by a suitably qualified and licensed health professional.

The use of oxaliplatin in the treatment of colorectal or pancreas cancer induces (>75% of patients) severe sensorimotor neuropathy decreasing the quality of life of cancer survivors. Today, no treatment remains univocal for these peripheral neuropathies. But preclinical works have demonstrated that donepezil (acetylcholinesterase inhibitor use for Alzheimer's disease) was able to prevent and treat neuropathic symptoms in oxaliplatin-treated rats. Present study aims to assess the therapeutic efficacy of donepezil on oxaliplatin-induced peripheral neuropathy (OIPN) in cancer survivors. Bibliographic data suggests an antineuropathic effect of donepezil in human and animal models. In clinic, a study have shown in healthy volunteers that donepezil (associated with gabapentin) reduced the pain threshold (better than gabapentin alone) caused by stimulation of the sural nerve, without severe adverse effect. Similarly, two studies in patients with neuropathic pain demonstrated that donepezil increases analgesic effect of gabapentin. Finally, a case report demonstrated an analgesic effect of donepezil in painful Alzheimer's disease patients. In animals, several studies demonstrated that donepezil induces analgesic and neuroprotective effects. Recently, a preclinical study demonstrated that donepezil induced antineuropathic effect in diabetic mice with neuropathic pain. Research unit INSERM U1107 (partner of the DONEPEZOX study) demonstrated the antineuropathic effects of donepezil in several animal models of chemotherapy-induced peripheral neuropathies, and very recently, a study have confirmed these results with oxaliplatin and cisplatin. These clinical and preclinical data have thus highlighted the potential beneficial effect of donepezil on neuropathic symptoms, without any significant adverse effects. Therefore the hypothesis is that the use of donepezil could reduce the symptoms of OIPN, limit the decrease in quality of life and the appearance of comorbidities (anxiety/depression) in cancer survivors. For this purpose, the investigators propose here a proof of concept, multicentre, phase II, randomised, double-blind, placebo-controlled clinical study. The primary objective will be the curative efficacy of donepezil on the severity of OIPN in patients who have completed oxaliplatin-based chemotherapy for the treatment of colorectal or pancreas cancer and have peripheral neuropathy of grade ≥2. This will be assessed using the EORTC QLQ-CIPN20 sensory scale. Our methodological choice to use the QLQ-CIPN20 as the primary endpoint will allow us to more accurately (and in a standardized manner) characterize neuropathic symptoms and assess the therapeutic effect of donepezil on these symptoms. In addition, as secondary objectives, we will study the effect of donepezil on neuropathic pain, the intensity of neuropathic symptoms, health-related quality of life, and the tolerance of donepezil. The 80 patients required will be randomized (1:1) to receive either placebo or donepezil (5 mg daily for 4 weeks and then 10 mg daily for 12 weeks as a single dose and according to tolerance and efficacy). Patients will be followed for 1 month after the end of treatment to assess the OIPN. As a proof of concept study, responder rate will be assessed only for Donepezil arm (primary objective) and compared between each treatment arm (secondary objective) after a minimum of 12 weeks of treatment. A responder will be defined as a patient with a decrease of neuropathic grade according to CIPN20 sensory score compraed to baseline.

Precision Acupuncture in the Treatment of Peripheral Neuropathy After Taxane Chemotherapy in Breast Cancer

This study seeks to evaluate the use of intermittent dosing as an alternative paradigm for patients with DRG stimulation in place for at least 1 year and minimum 50% pain relief in the targeted area. Patients will be prospectively randomized to one of two stimulation paradigms both of which involve intermittent dosing at 30 seconds ON and 90 seconds OFF. Group 1 will have their frequency set at 20 Hz with amplitude levels adjusted in order to remain in the therapeutic window (subthreshold stimulation). Group 2 will have their frequency set at 5 Hz with amplitude levels adjusted in order to remain in the therapeutic window (subthreshold stimulation) This study will be performed in a crossover fashion, meaning patients will be changed to the alternate dosing regimen at the 13-week time period. Patients will be seen and evaluated prior to randomization and reprogramming, and thereafter evaluated at 4, 8, and 12-weeks. At the 12-week time period, patients will begin a 1-week washout period of continuous stimulation. At the 13-week time period, patients will be evaluated, crossed over to the other study arm and thereafter evaluated at 17, 21, and 25-weeks.

The goal of this double-blind prospective randomized clinical trial is to determine if the effect of intravenous erythropoietin is superior to the effect of intravenous methylprednisolone in cases of toxic optic neuropathy 4 weeks after therapeutic intervention. The main question it aims to answer: • Is there a difference in the visual recovery of toxic optic neuropathies treated with intravenous methylprednisolone in comparison with those treated with intravenous erythropoietin?

The objective of the study is to investigate the effects of a 16-week combined qigong and acupressure intervention on reducing self-reported chemotherapy-induced peripheral neuropathy (CIPN) severity, objective measures of CIPN severity, lower-extremity functioning, handgrip strength, fall incidence, and health-related quality of life post-intervention among post-chemotherapy adult cancer patients. This will be a 2-arm assessor-blinded randomized controlled trial that will follow the CONSORT guidelines. A total of 104 cancer patients aged ≥18 who have completed neurotoxic chemotherapy at least 1 month prior to enrolment and experiencing CIPN will be recruited and randomized into combined qigong and self-administered acupressure intervention and wait-list control groups. The intervention group comprises of twice-weekly supervised group sessions and three times-weekly self-practice prescription (30 min each time) on days without group sessions. The control group will be offered a free modality of their choice after the last follow-up. The participants will receive usual care alone during the study period.

Diabetic Peripheral Neuropathy (DPN) is one of the most common chronic complications in type 2 diabetes, conventional drug therapy can only target a single pathogenesis but not treat Diabetic Peripheral Neuropathy (DPN) fundamentally. As a novel technique, stem cell transplantation provides a new option for patients with DPN. In 2012, Wuhan Central Hospital, took the lead in carrying out clinical research on the treatment of DPN with autologous bone marrow stem cells in China, and patients were significantly relieved. Based on this research, our clinical trial is to evaluate the safety and efficacy of HUC-MSCs in the treatment of refractory diabetic peripheral neuropathy (DPN) by formulating standard operating procedures (SOP) and quality standards (QS) to explore the possible mechanism of HUC-MSCs in the treatment of DPN.

The main purpose of this study is to determine the safety and efficacy of LY3556050 versus placebo in participants with diabetic peripheral neuropathic pain (DPNP). The study will lasts approximately 24 weeks, across 3 study periods.
