Active clinical trials for "Pain, Intractable"

Neuropathic pain is difficult to control because it is only partially sensitive to opioid analgesics, and requires the addition of other therapies such as antidepressants and epileptics. Ziconotide is a drug that is used to treat neuropathic pain in patients who have had inadequate pain control with prior combination of medicines.

The objective of this study is to evaluate the efficacy of BurstDR dorsal column stimulation, compared with conventional medical management, in improving pain and back-related physical function in subjects suffering with chronic, refractory axial low back pain with a neuropathic component, who have not had lumbar spine surgery and for whom surgery is not an option.

The main objective of this study is to analyze the impact on the health-related quality of life of patients with refractory symptoms, who have been referred to the HUGCDN Chronic Pain Unit for adjuvant palliative treatment with ozone therapy between June-2022 and December-2025

Ziconotide (Prialt®) is a powerful analgesic, approved in Europe since 2005, and reserved for the intrathecal route. Ziconotide is a protein of 2500 Daltons isolated from a cone-snail: Conus Magus, acting by blocking the N-type voltage-sensitive calcium channels. Its efficacy has been proven by 3 randomized clinical trials. It is particularly effective on chronic refractory neuropathic pain, and its main advantages are its power of action, the absence of bone marrow toxicity, and the absence of respiratory depression. In addition, there were no signs of withdrawal when stopping the drug, or of tachyphylaxis. However, during these studies many adverse reactions became evident, especially neuropsychiatric reactions, which limited its use. This toxicity was mainly related to the administration of too high doses, especially at the start of treatment. There is a lack of data on the current use of ziconotide in current practice. The objective of the study will be to describe the practical methods of using intrathecal treatments containing ziconotide in different settings of patients with severe chronic pain requiring intrathecal analgesia.

Background: Cancer-induced bone pain (CIBP) is common in people with cancer. Bone cancer can also lead to anxiety, depression, and reduced mobility and quality of life. Researchers believe a research drug called resiniferatoxin (RTX) may be able to help. Objective: To learn whether RTX is safe and can reduce cancer induced bone pain. Eligibility: People ages 18 and older with CIBP that is not relieved by standard treatments Design: Participants will have up to 6 outpatient visits over about 7 months. These will include: Medical history Physical exam Blood and urine tests. Thermal testing: a disk placed on the skin to test ability to sense temperature in and around the area of pain Chest x-ray EKG: stickers are placed on the chest to measure heart signals ECG: measures electrical activity of the heart Participants will have 1 inpatient visit lasting 2-4 days. This will include: Catheter inserted into a vein in the arm. They are given anesthesia, sedation, and x-ray contrast. A needle is passed through the skin of the back to inject the RTX. Participants will keep a log of the pain medications they take after surgery. Participants will be called 1 week and 2, 3, and 4 months after the injection. Participants will be mailed surveys and questionnaires to complete 2, 3, and 4 months after the injection.

Refractory pain is a prevalent condition that negatively affects patients' quality of life. Intrathecal implantable systems have been proposed as a treatment option for refractory pain. However, real-world data on the effectiveness and safety of these therapies in Spain are scarce. This study aims to obtain real-world data on the effectiveness and safety of intrathecal implantable systems for refractory pain treatment in Spain.

This Phase 2 study assesses the safety and efficacy of a single injection of Resiniferatoxin versus placebo for the treatment of intractable advanced cancer pain.

Medtronic, Inc. is sponsoring the SENSE SCS clinical study, a prospective, multi-center, post-market, non-randomized, observational study with a hybrid decentralized model of execution, utilizing a mobile application for the collection of patient reported outcomes (PROs). The purpose of the study is to evaluate workflow of a mobile application for collection of PROs and to gather data on patient experience with spinal cord stimulation therapy.

A number of studies from the literature suggest important behavioral, psychosocial, or radiologic changes occur following significant neurologic events or interventions such as stroke, neurosurgery, medications, radiation, systemic therapy, or injury. The purpose of this study is to describe these changes with advanced neurologic imaging and targeted neurologic and neuropsychiatric assessments. This is a non-interventional observational study of minimal risk to participants as there is no medical intervention. The results of this study will be used to inform patients, scientists, and society in the development of future treatments.

This study will demonstrate that functional improvement measures over a 6-month period for chronic low back patients under the care of Primary Care Provider (PCP), using a therapeutic plan formulated initially by the Pain Medicine Specialist (PMS), are equivalent to those under the care of the PMS only. Chronic low back pain patient will be initially be evaluated by the PMS. If no interventional pain therapy is required, a multimodal therapeutic plan (pharmacological and/or non-pharmacological) will be formulated to manage the chronic low back pain. Patients will be randomized into one of the two groups: Group 1 - Subjects will be treated monthly for the following 6 months by PMS, and Group 2 - Subjects will be treated by their own PCP for monthly visits for 6 months.
