Active clinical trials for "Polyradiculoneuropathy, Chronic Inflammatory Demyelinating"

This phase II trial studies the side effects and how well carmustine, etoposide, cytarabine and melphalan together with antithymocyte globulin before a stem cell transplant works in treating patients with autoimmune neurologic disease that did not respond to previous therapy. In autoimmune neurological diseases, the patient's own immune system 'attacks' the nervous system which might include the brain/spinal cord and/or the peripheral nerves. Giving high-dose chemotherapy, including carmustine, etoposide, cytarabine, melphalan, and antithymocyte globulin, before a stem cell transplant weakens the immune system and may help stop the immune system from 'attacking' a patient's nervous system. When the patient's own (autologous) stem cells are infused into the patient they help the bone marrow make red blood cells, white blood cells, and platelets so the blood counts can improve.

SIDEC - (Subcutaneous Immunoglobulin in De-novo CIDP) ia a study designed as a randomized, parallel study with an open-label extension phase. The aims are to compare the effect of SCIG and IVIG in 60 treatment-naïve CIDP patients, and to detect the lowest effective dosage for maintenance treatment.

Antibody-mediated idiopathic inflammatory diseases of the nervous system (also known as autoimmune diseases of the nervous system) are autoimmune diseases in which autoimmune cells and immune molecules attack the nervous system as the main pathogenic mechanism. In the immune response, pathogenic antibodies acting on autoantigens of the nervous system are collectively referred to as autoantibodies of the nervous system, and antibody-mediated idiopathic inflammatory diseases of the nervous system can occur in the central nervous system, peripheral nervous system, and neuromuscular junctions , and muscles. In this study, we will recruit three kinds of autoimmune diseases of nervous system including Neuromyelitis Optica Spectrum Disorder (NMOSD), Myasthenia Gravis (MG), Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP) and Immune-Mediated Necrotizing Myopathy (IMNM). B-cell maturation antigen (BCMA) is expressed on the surface of plasma cells, thus making it an ideal target for targeted therapies. Chimeric antigen receptor (CAR) T cells against BCMA offers another potential therapeutic option to eliminate plasma cells in patients with neurological autoimmune diseases driven by abnormal antibody who still suffer recurrent attacks from conventional treatments. In the current study, the safety and efficacy of a novel CAR-T cell therapy using CT103A cells, are evaluated in patients with relapsed/refractory antibody-mediated idiopathic inflammatory diseases.

A randomized, open-label, prospective, multicenter study designed to investigate 2 dose levels in pediatric subjects 2 to ≤ 17 years of age with confirmed or possible CIDP, either previously exposed to IVIG treatment or unexposed to IVIG treatment

Primary Objectives: Part A: Efficacy of SAR445088 across three subpopulations of CIDP patients: standard of care (SOC)-Treated, SOC-Refractory and SOC-Naive Part B:Long-term safety and tolerability of SAR445088 in CIDP Secondary Objectives: Part A: Safety and tolerability of SAR445088 in CIDP Immunogenicity of SAR445088 Efficacy of SAR445088 with overlapping SOC (SOC-Treated group) Part B: Durability of efficacy during long-term treatment with SAR445088 in CIDP Long-term immunogenicity of SAR445088 in CIDP

This is a randomized controlled study evaluating safety and efficacy of repeated immunoadsorption versus immunoglobulins in steroid-refractory Chronic Inflammatory Demyelinating Polyneuropathy (CIDP).

The main purpose of this study is to evaluate the safety and efficacy of nipocalimab compared to placebo in delaying relapse in adults with chronic inflammatory demyelinating polyneuropathy (CIDP) who initially respond to nipocalimab in Stage A.

Safety and Efficacy of Different PANZYGA Dose Regimens in Pediatric Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP) Patients

This is a multi-center, randomized, quadruple-blind, placebo-controlled study to evaluate the efficacy and safety of batoclimab in adult participants with active CIDP. The study includes a 4-week Screening Phase, an up to 12-week Washout Phase, a 12-week Randomized Treatment Phase (Period 1), an up to 24-week Randomized Withdrawal Phase (Period 2), a 4-week Safety follow-up for participants not entering Long-Term Extension (LTE), and a 52-week LTE Phase. The total study duration will be up to 104 weeks. Eligible participants will be assigned to one of three cohorts (A, B, C) based upon their CIDP treatment at the time of screening.

The main aim of the study is to check for side effects from TAK-771, and to check how well TAK-771 controls symptoms in Japanese participants with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) and multifocal motor neuropathy (MMN) The participants will be treated with TAK-771 for 45 months as a maximum. There will be many clinic visits. The number of visits will depend on the infusion cycles of study drug (every 2, 3, or 4 weeks).
