A debilitating consequence of diabetes mellitus (DM) is neuropathy which globally affects between 20 -30% of diabetic patients and up to 50% in other studies. The incidence of diabetic neuropathy (DN) is estimated to be up to 45% for type 2 diabetic patients and 59% for type 1diabetic patients in USA.(DN) is the most common complication of DM.The pathophysiology of DN is promoted by several risk factors: micro vascular disease, neural hypoxia, and hyperglycemia-induced effects.At the molecular level, the primary cause of diabetic complications is known to be hyperglycemia, which disrupts cellular metabolism by the formation of reactive oxygen species (ROS).In the aspect of nerve functions, ROS formation increases neuron's susceptibility to damage. In addition, hyperglycemia impedes production of angiogenic and neurotrophic growth factors, which are necessary for normal function of neurons and glial cells and maintenance of vascular structure.No definitive disease-modifying treatments have been to reverse DN. The current treatment focuses on tight glycemic control which can reduce potential risk factors for further nerve damage and DN-associated pain management.In many studies, deficiency of neurotrophic factors and lack of vascular support have been regarded as key factors in the development DN.Mesenchymal stem cells (MSCs) are particularly attractive therapeutic agents because of their ability to self-renew, differentiate into multi lineage cell types, and locally secrete angiogenic cytokines, including basic fibroblast growth factor (bFGF) and vascular endothelial growth factor (VEGF) .These factors were reported to prompt neovascularization and have support for neural regeneration.It was plausible that MSCs may also be an effective therapeutic agent for the DN treatment through the paracrine effects of bFGF (Shibata et al., 2008) and VEGF and their potential to differentiate into neural cells such as astrocytes, oligodendrocytes , and Schwann cells.The adherent nature of MSCs makes them easy to expand in culture and an attractive candidate to use in cell therapy.Therefore, cell therapy has recently emerged as an attractive therapeutic strategy to meet the needs of both neurotrophic and vascular deficiencies of DN.Proper diagnosis of DN depends on the pattern of sensory loss, reflex test, electrodiagnostic studies, and imaging
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).
Study CLO-311 is a multicenter, open-label, single-arm study to assess the long-term use of Clonidine Gel in the treatment of pain associated with PDN. Subjects who have completed their 12-week participation in Study CLO-290 or Study CLO-310 are eligible to rollover into this study and receive active study drug in an open-label manner.
The primary purpose of this study is to determine the degree of loss of epidermal nerve fibers near a foot wound in patients with diabetic foot ulcers. The secondary purpose will be to determine whether the degree of epidermal nerve fiber loss, the clinical examination, nerve conduction studies or the molecular profile correlates with appearance of lower extremity ulcers in patients with diabetes.
A multicenter, Phase 2a, randomized, double-blind, placebo (vehicle)-controlled, parallel-group, dose-finding study designed to evaluate the efficacy, safety and tolerability of NRD135S.E1 in adult patients with diabetes mellitus type 1 or 2 with neuropathic pain. Potential study patients will sign informed consent prior to undergoing any study-related procedure.
The proposed study will randomize participants with diabetic peripheral neuropathy into two groups. One group of participants will receive standard-of-care counseling while the other group will undergo supervised exercise and counseling to increase physical activity.
An interventional study to investigate the efficacy and safety of diepalrestat (BNV-222) in diabetic patients with diabetic peripheral neuropathy. Subjects will receive twice daily an oral dose of diepalrestat, an aldose reductase inhibitor, or placebo to investigate the effect on motor nerve conduction velocity (MNCV) and symptomatic clinical responses over 12 months of treatment. Subjects will be assessed at screening and baseline, with office visits every 12 weeks, for a total of 6 visits. The study will explore in a double-blind fashion, the effect of two doses of diepalrestat, 150 and 300 mg, to reduce the loss in nerve conduction velocity that is expected to be demonstrated in the group randomized to placebo treatment for up to 12 months.
The proposed study is a randomized, double-blinded clinical trial to evaluate the efficacy of a course of laser therapy on peripheral neuropathic pain in persons with diabetes. The hypothesis is that laser therapy will produce significant improvement on measures of self-reported pain among adults with diabetes.
The overall aim of this study is to confirm the utility of corneal confocal microscopy (CCM) as a new technique to rapidly and non-invasively assess diabetic neuropathy (DN) in children. This study will be divided into two phases: Phase 1 will be a cross-sectional study of children with type 1 diabetes and normal controls, while phase 2 will be a longitudinal assessment of a subgroup of children with type 1 diabetes recruited during Phase 1.
