Filter by:The purpose of this study is to evaluate the safety profile of orally administered tapentadol ER dosages of 100 to 250 mg twice daily in patients with chronic, painful diabetic peripheral neuropathy (DPN) over long-term exposure of up to 1 year.
Patients will be switched from their current medication for painful diabetic peripheral neuropathy to evaluate the safety and efficacy of pregabalin as compared to placebo. All patients will receive pregabalin, and half of patients will receive placebo at some point during the study.
This trial is assessing the analgesic efficacy and safety of a new central analgesic in subjects with pain due to diabetic peripheral neuropathy (DPN).
The purpose of the study is to learn if long-term treatment with DVS SR is safe for treating the pain and other symptoms associated with diabetic peripheral neuropathy.
The purpose of this study is to evaluate the efficacy, safety, and tolerability of orally administered tapentadol extended release (ER) at dosages of 100 to 250 mg twice daily compared with placebo in patients with moderate to severe pain due to chronic, painful diabetic peripheral neuropathy (DPN) who tolerated tapentadol (ER) and have an initial treatment effect (pain improvement) after a 3-week, open-label titration period.
Fall risk is increased in people with diabetic peripheral neuropathy (DPN) and yet, minimal research has been conducted to identify appropriate fall risk assessment tools and improve our understanding of falls in these individuals. Purpose: The primary purpose of this study is to establish a foundation of knowledge needed to address falls in people with DPN. This will be accomplished through 1) comparing the validity of 4 fall risk assessment tools, 2) identifying risk factors for falls and 3) determining how quality of life is influenced by factors related to falls in people with DPN.
Neuropathic pain occurs as a result of damage or disease of the peripheral or central nervous system. Regardless of its cause, neuropathic pain (NeP) leads to a characteristic clinical picture characterized by ongoing pain with steady or dysesthetic pain, such as burning or aching, and paroxysmal pain such as shooting or stabbing. In conditions such as diabetic neuropathy, changes in the membrane-bound proteins that form ion channels may alter the electrical properties of the injured neuron, called remodeling. The net effect of membrane remodeling is greater excitability of neurons, leading to a tendency towards action potential generation and propagation in injured primary sensory neurons which occurs in the context of nerve injury and disease. Over the past decade, a new endogenous cannabinoid receptor-mediated system within the nervous system and upon immune-mediated cells has been described. The cannabinoid receptor system consists of two receptors, CB1 and CB2 receptors, as well as endogenously produced endocannabinoids which agonize these receptors. This is a multicenter trial amongst Western Canadian sites to compare the efficacy of nabilone versus placebo in treating patients with chronic neuropathic pain (NeP) due to diabetic peripheral neuropathy (DPN). A one-week screening period will occur, during which pain scores and sleep scores will be tabulated. Following screening, a 4-week period of single blind treatment with flexible dosing of nabilone at 0.5 - 4 mg/day will initiate. All subjects will begin with nabilone therapy of 1 mg daily for a minimum of 4 days, with the dose of the study medication assessed and adjusted either upwards or downwards as needed to balance efficacy for pain control with tolerability of possible side effects. All subjects who experience at least a 30% reduction in their weekly mean pain score during the single blind flexible dosing phase will be considered a responder, and will be further continued in the study. During the double-blind portion of the study, subjects randomized to nabilone will continue on the dose of nabilone achieved at the completion of the single-blind phase, and this dose will be maintained throughout the double-blind phase. Subjects randomized to placebo will receive 1 mg of nabilone daily for one week, followed by 4 consecutive weeks of placebo. This dose of nabilone will permit a tapering for those subjects achieving a higher daily dose of nabilone during the single-blind phase, or will maintain those who were taking only 1 mg per day in the single-blind phase, preventing an abrupt termination of treatment in subjects who are randomized into the placebo portion of the study.
The purpose of the study is to determine whether or not surgical decompression of the common peroneal, tibial, and deep peroneal nerves in the legs of persons with diabetic peripheral neuropathy is effective treatment.
The purpose of this study is to assess the safety and tolerability of injecting VM202 in the leg muscle in patients with painful diabetic neuropathy (DPN). The study will also assess the potential of VM202 to reduce the pain associated with DPN.
The use of regional anesthesia for nerve block in diabetic patients with peripheral neuropathy is currently made on a case-by-case basis, also remains underlying uncertainty regarding the preferred technique and the likelihood of block-related nerve injury. For this many diabetic patients with otherwise healthy nerves may receive general anesthesia instead of regional anesthesia, thus giving up the benefits associated with the latter technique, including a decrease in health complications and superior analgesia following the operation. Ultrasound is used to identify the target nerve and guide needle insertion for nerve blocks, may be a useful tool to detect the presence and severity of neuropathy prior to block placement, a recent study demonstrated a statistically significant increase in the sonographic cross-sectional area of the posterior tibial nerve (PTN) in all diabetic patients who had abnormal motor transmission on nerve conduction studies. For regional anesthesiologists, the ultimate goal of detecting peripheral neuropathy and in particular, diabetic neuropathy by US is to avoid nerve injury. To do so, the association between US-detected diabetic neuropathy and block-related nerve damage must be first established, hence the purpose of this study. We aim to examine whether the cross-sectional area of PTN as assessed by preoperative US can predict nerve injury as assessed by worsening nerve conduction studies following PTN block inpatients scheduled to receive an ankle block. A further subgroup analysis will be performed in diabetic patients. We hypothesize that the cross sectional area of the PTN will correlate with motor conduction velocity on nerve conduction studies (NCS) following PTN block in patients with peripheral neuropathy. All eligible patients will undergo NCS to confirm or exclude distal neuropathy. Patients without neuropathy will be excluded from further participation in this study. Also excluded will be diabetic patients with neuropathy caused by genetic, metabolic and inflammatory diseases as well as toxic agents and drug induced. A systematic US examination of the PTN will be performed for all patients. After Block administration at surgery day the block successes will be assessed and for the purposes of the present study, patients in whom the block was not successful will be excluded from further intervention and data analyses. Eight weeks after surgery, all study patients will return to hospital for repeat NCS and US.
