DECODING Study (Dermal Electrochemical Conductance in Diabetic Neuropathy)

NeuropathyDiabetic2 more

Diabetes mellitus is the leading cause of polyneuropathy in the Western world. Diabetic neuropathy is a frequent complication of diabetes and may have great clinical transcendence due to pain and possible ulceration of the lower extremities. It is also a relevant cause of morbidity and mortality in patients with diabetes. Although the cause of polyneuropathy in patients with diabetes is only partially known, it has been associated with chronic hyperglycaemia suggesting the possible aetiopathogenic implication of advanced glycosylation end-products. The strategy of choice in the medical management of diabetic neuropathy is early detection since glycaemic control and the use of certain drugs may prevent or slow the development of this disease. Diabetic neuropathy most often presents with a dysfunction of unmyelinated C-fibers, manifested as an alteration of the sweat reflex of the eccrine glands. This dysfunction can now be demonstrated using a newly developed technology which measures dermal electrochemical conductivity. This noninvasive test is easy and cost-effective. The aim of the present study is to evaluate the feasibility and effectiveness of dermal electrochemical conductance measurement (quantitative expression of the sudomotor reflex) as a screening test for the diagnosis of diabetic neuropathy in patients in primary care.

Clinical Trial Designed to Determine the Safety and Efficacy of EMA401 in Patients With Painful...

Diabetic Neuropathies

The study consists of two periods, the Screening Period (~3 weeks) and Treatment Period (12 weeks). Eligibility for the study will be determined by Screening tests, physical examination/medical history, and fulfilment of eligibility criteria including assessment of pain completed during the Screening Period. Potential participants will be required to provide written informed consent prior to any study-specific Screening procedures being performed. Following Screening assessments, patients will be randomized to receive either EMA401 300 mg BID or placebo. Patient study visits during the Treatment Period are at the end of baseline/randomization visit, and end of Weeks 3, 6, 9, and 12, for assessments.

Safety and Efficacy Study of BC-DN-01 in Painful Diabetic Peripheral Neuropathy

Diabetic NeuropathyPainful

A combined Phase 1 & 2 study to evaluate the safety and effectiveness of a new diabetic neuropathy topical cream, containing benfotiamine, will be performed at 5 clinical sites and plans for BC-DN-01 administration in up to 135 volunteer patients using a standard Phase 1 + 2 design. Up to 15 subjects will receive BC-DN-01 in Study Phase 1 and up to 120 subjects will receive BC-DN-01 or placebo in Study Phase 2. In Phase 1, a BC-DN-01 dose delivering 160mg benfotiamine/day (80mg twice daily) will be administered for the first 7 days. On visit day 0, patients will commence study treatment. Patients will be interviewed by phone on day 3 and return to clinic on day 7 for safety assessments. If the drug is well-tolerated and no significant adverse events experienced, the total daily BC-DN-01 dose will be increased on days 7-14 to 320mg benfotiamine/day (160mg b.i.d.). Patients will be interviewed by telephone on day 10 and return to clinic on day 14 for safety assessments. Once the safety profile has been determined in Phase 1 as acceptable, the Phase 2 study will be initiated to evaluate clinical efficacy of BC-DN-01. Phase 2 is a randomized, placebo-controlled, double-blind, parallel study. Participants receive placebo or BC-DN-01 based on 1:1 randomization. Each patient will apply 4g of the study medication to each leg twice-a-day administering 320mg benfotiamine dose/day for 12 weeks. Participants will be evaluated in the clinic at baseline and at 4, 8, and 12-week time points; study staff will interview the patients by telephone on weeks 2, 6, and 10. The primary endpoint of the phase 2 trial is reduction in DPN pain measured by the Brief Pain Inventory. Phase 2 patients will be invited to give written consent to take part in biopsy sampling and additional gene expression analysis.

Microcirculatory Vasomotor Changes in Type 2 Diabetes With Peripheral Neuropathy

Diabetic Neuropathy PeripheralSmall Vessel Disease of Diabetes Mellitus2 more

Microcirculatory flow is subject to cyclic changes under the influence of heart rate, respiration, myogenic activity, neurogenic factors and endothelial factors. Microcirculatory oscillations (vasomotion) contribute significantly to tissue perfusion. Vasomotion analysis allowed to discriminate normoglycemic subjects, prediabetic subjects and diabetic subjects. Furthermore, changes in vasomotion can precede the emergence of global signs of microangiopathy complications in type 2 diabetes. In fact, few studies reported impaired vasomotion in type 2 diabetes with peripheral neuropathy. Vasomotion analysis after vasodilator (6-min walking test and hyperthermia) and after vasoconstrictor (foot lowering) stimulus could be an effective diagnostic tool to sharpen the diagnostic. Objectives and Methodology: to study vasomotion at baseline and after exercise, hyperthermia and foot lowering within 3 groups of patients: diabetic without peripheral neuropathy, diabetic with subclinical peripheral neuropathy and diabetic with peripheral neuropathy and one group of sex- age- and body mass index-matched healthy control subjects. All the subjects will benefit from a clinical, anthropometric, level of physical activity and biological evaluations. Type 2 diabetes participants will benefit from neuropathy evaluation. In addition, cutaneous microcirculation (perfusion and vasomotion) by means of Laser Doppler Flowmetry and Laser Speckle Imaging will be recorded at rest and after different stimuli (exercise, hyperthermia and foot lowering).

Efficacy, Safety, Tolerability and Pharmacokinetics of Concomitant Administration of Tramadol With...

Diabetic PolyneuropathyPostherpetic Neuralgia

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.
