Active clinical trials for "Complex Regional Pain Syndromes"

The aim of this trial was to investigate the efficacy and safety of intravenous neridronic acid in subjects with Complex Regional Pain Syndrome (CRPS). The trial consisted of an Enrollment Period lasting up to 60 days, Treatment Period A consisting of 4 infusions (neridronic acid or placebo) over 10 days, and a Follow-up Period 1 until Week 26. At Week 26, participants not meeting the pre-specified criteria to continue into Treatment Period B continued in Follow-up Period 2 until Week 52. Participants meeting the pre-specified criteria entered the open-label Treatment Period B with 4 additional infusions (neridronic acid) over 10 days and follow-up visits until Week 52.

The purpose of this study is to determine whether epidural and ketamine infusions are effective in the treatment of Complex Regional Pain Syndrome (CRPS).

The purpose of this study is to see if an FDA-approved drug (Gralise) can help people with certain types of neuropathic pain without causing too many side effects.

Alpha 2 macroglobulin (A2M) is a plasma protein that acts as a molecular trap for inflammatory factors such as tumor necrosis factor (TNF). After plasma is enriched for A2M, it may be injected for treating chronic inflammation. Plasma enriched for A2M may be considered as a possible injectable agent to counteract inflammation that may occur with a cervicobrachial pain syndrome. This study reports on an experiencing using A2M to treat cervicobrachial syndrome which was predominant for either musculotendinous or neuralgic features.

The purpose of this study is to assess the efficacy of pregabalin in patients with complex regional pain syndrome Type I and to determine whether it provides clinically significant pain relief and whether it improves functioning of the upper limb.

CRPS is a complex pain condition that usually develops in response to trauma and immobilization which is very painful and debilitating. There is no consensus about the underlying mechanisms which might be a combination of mentally and physically factors. At the moment, better diagnostic clarification and better pain relieving treatment is needed. The aim of this study is to investigate changes in the perception of pain in patients with Complex Regional Pain Syndrome (CRPS), and whether this perception can be affected by treatment with transcutaneous electrical nerve stimulation (TENS) on the painful area. The study will consist of two parts. One in which patients' perception of pain will be compared to the perception of pain in healthy controls. Another in which the included patients are randomly allocated into a group receiving medical treatment plus treatment with transcutaneous electrical nerve stimulation on the painful area or in a group receiving medical treatment as usual (MED).Patients will be evaluated four times. At the start of the study, immediately after treatment, and again at 6 and 12 months after treatment. The evaluation consists of an overall assessment of pain, response to standardized sensory stimuli, and questionnaires about quality of life, physical capacity and mentally/socially well-being.

Pain remains the most debilitating symptom for adult patients suffering from complex regional pain syndrome (CRPS). Most CRPS patients gain little to no relief from current painkillers. The purpose of this study is to evaluate the efficacy and safety of ethosuximide in search of much-needed adjunctive therapy to relieve the pain and suffering associated with CRPS.

This study is an open-label study to determine the feasibility of Motor Cortex Stimulation (MCS) in the treatment of patients with chronic pain of the face or upper extremity. MCS will be delivered by use of an electrode and pulse generator, which are FDA approved for spinal cord stimulation but are not approved for MCS. The study has as a single-arm design with the subject at baseline serving as a control for the response to MCS.

The aim of this trial was to investigate the safety of intravenous neridronic acid in patients with complex regional pain syndrome (CRPS). The trial was divided into 3 periods: a 60-day enrollment period, a treatment period consisting of 4 infusions over 10 days, and a follow-up period of approximately 50 weeks (with visits at Week 2, Week 6, Week 12, Week 26, Week 39, and Week 52).

This clinical trial is being conducted to demonstrate the efficacy of neridronic acid in the treatment of pain associated with complex regional pain syndrome type I (CRPS-I). The trial is divided into 3 periods: a 60-day enrollment period, a 12-week trial period, and an extended follow-up period with visits at Month 6, Month 9, and Month 12. The extended follow-up period will be terminated for all participants after the last participant enrolled completes their Month 6 visit (Visit 9). The double-blind will be maintained throughout the 12-week trial period and extended follow-up period.
