Polyneuropathy, inflammatory demyelinating, chronic

This early-stage trial tests a single infusion of allogeneic CAR-T cells, called RN1201, in 18 adults with autoimmune diseases that have not responded to standard treatments. The therapy aims to reset the immune system by targeting and eliminating faulty immune cells. Before the …

This study tests a new medicine called empasiprubart against the standard treatment (IVIg) for people with chronic inflammatory demyelinating polyneuropathy (CIDP), a nerve disease that causes weakness and numbness. About 218 adults who have used IVIg before will receive either t…

This phase 3 trial tests whether empasiprubart, given by IV infusion, can help adults with chronic inflammatory demyelinating polyneuropathy (CIDP), a nerve disorder that causes weakness and disability. The study will enroll 160 participants. For the first 6 months, some get the …

This early-stage trial is testing a new cell therapy called GT719 in 30 adults with recurrent or hard-to-treat neurological autoimmune diseases. The goal is to see if it is safe and how long the cells last in the body. Researchers will also look for early signs that it might help…

This study tests whether a weekly under-the-skin antibody treatment (XEMBIFY) provides similar blood levels as a standard IV infusion (Gamunex-C) given every 3 weeks in people with CIDP, a chronic nerve disorder. About 40 adults who are stable on IVIG will first receive Gamunex-C…

This study tests whether a medicine called Panzyga can prevent major infections in people with autoimmune or rheumatic conditions who have low antibody levels after receiving B-cell depletion therapy. About 360 adults will receive either Panzyga or a placebo, and researchers will…

This study is testing a new blood filter called the Plasma Filter PX2. It is used in a procedure called therapeutic plasma exchange, which removes harmful substances from the blood of people with autoimmune diseases. About 46 adults will take part, and the study will check if the…

This study compares two treatments for CIDP, a nerve condition that causes weakness and numbness. It involves 20 adults who did not get better with steroids. One group receives a blood-filtering procedure called immunoadsorption, and the other receives standard antibody infusions…

This study follows 200 adults with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) who are starting treatment with efgartigimod. Researchers will track changes in disability, grip strength, and quality of life over up to 2 years in everyday clinical settings. The…

This early-stage study tests a new mRNA-based treatment (ABO2203) for people with autoimmune diseases that haven't improved with standard care. The therapy works by directing the body's immune cells to attack and control overactive immune cells causing the disease. The study will…

This program offers efgartigimod PH20 SC to adults with CIDP who cannot join clinical trials and have not been helped by existing treatments. The drug is injected under the skin and aims to control the disease. The program continues until the patient stops treatment or the drug b…

This study is testing whether the shingles vaccine (RZV) works and is safe for adults with autoimmune rheumatic diseases like rheumatoid arthritis or lupus who are taking immune-suppressing drugs. Two hundred participants will receive two doses of the vaccine. Researchers will me…

This study is looking for the genes that cause certain immune system problems. Researchers want to understand why some people get sick and others don't, even in the same family. Up to 5,000 people with immune disorders and their relatives will give blood or cheek cell samples for…

This study will analyze DNA from up to 20,000 people, including those with immune disorders and their relatives, to find genetic variants linked to conditions like atopy, autoimmunity, and primary immunodeficiency. Researchers will also study how best to return genetic results to…

This registry follows pregnant women who have taken mycophenolate, a drug used to prevent organ rejection and treat autoimmune diseases. Researchers will collect data on pregnancy complications and birth defects up to one year after birth. The goal is to better understand the dru…

This observational study follows about 200 people in the United States who have chronic inflammatory demyelinating polyneuropathy (CIDP) and still experience disability despite at least three months of standard treatment. Researchers will track changes in disability scores and ex…

This study is measuring a protein called STIM1 on the surface of immune cells in 670 people with various autoimmune diseases. The goal is to find which diseases have high levels of this protein, which could help researchers develop new antibody-based treatments. Participants prov…

This study looks at whether smartwatches can help monitor chronic inflammatory demyelinating polyneuropathy (CIDP), a rare nerve disease that causes weakness and numbness. 35 adults with CIDP who use subcutaneous immunoglobulin therapy at home will wear a smartwatch for 12 months…

This study collects and freezes testicular tissue from boys and young men who are at risk of becoming infertile due to cancer, autoimmune disorders, or their treatments. The tissue is stored in a research bank, with the hope that future medical advances will allow it to be used t…

This study collects blood samples from 1000 people with rare neurological diseases that may be autoimmune. Researchers will use the samples to find new biomarkers and autoantibodies, which could help diagnose and treat these conditions in the future. Participants give extra blood…

This study looks at 320 adults who are about to start strong immune-suppressing therapy and have already had at least two COVID-19 shots. Researchers want to find out if giving a COVID-19 booster right before starting therapy or waiting six months provides better protection. Part…

This study follows pregnant women who have taken efgartigimod for myasthenia gravis or CIDP, as well as women exposed only during breastfeeding. Researchers will monitor pregnancy outcomes and infant health, including birth defects, to better understand the drug's safety. The goa…

This study is creating a large registry of 800 people receiving biologic medications for immune conditions like autoimmune diseases and primary immune deficiencies. Researchers will collect blood samples and health data to better understand how these treatments work and who respo…

This study looks at how a person's body composition (fat and muscle) affects the way immunoglobulin G (IgG) moves through the body after being given through a vein or under the skin. Researchers will enroll 20 adults with a nerve condition called CIDP who already receive IgG ther…

This study looks at how well therapeutic plasma exchange (a blood-filtering procedure) works for people with autoimmune neurological diseases. Researchers at Al-Azhar University Hospitals will follow 60 Egyptian patients to see if their symptoms and daily function improve. The go…
