Autoimmune encephalitis

This Phase 2 trial tests efgartigimod PH20 SC, a drug that lowers harmful antibodies, in 170 adults and teens with autoimmune encephalitis (AIE). Participants receive either the drug or a placebo, and researchers measure changes in disability and symptoms over up to 3 years. The …

This trial tests whether plasma exchange (a blood-cleaning procedure) given every other day works as well as daily sessions for children with autoimmune encephalitis, a condition where the immune system attacks the brain. The study involves 22 children who are randomly assigned t…

This study tests whether a low dose of blinatumomab, a drug originally used for leukemia, can help people with severe autoimmune encephalitis or cerebellitis that hasn't responded to standard treatments. The drug targets and depletes certain immune cells (B cells) that are mistak…

This early study tests an experimental drug called STR-P005 in people with autoimmune diseases that have come back or not improved with standard treatments. The drug is given through an IV in multiple doses. The main goal is to check safety and see how the body handles the drug. …

This early study tests a new drug called STR-P005 in 18 people with autoimmune diseases that have not responded to standard treatments. The main goal is to check safety and find the best dose. Participants receive the drug by infusion in different schedules, and researchers will …

This early-phase trial will test a new treatment called QT-019C in up to 15 adults with relapsed or refractory neurological autoimmune diseases, including multiple sclerosis, neuromyelitis optica, and myasthenia gravis. The treatment uses donor-derived CAR T-cells that target two…

This early-stage trial is testing a new treatment called C-CAR168, which uses a patient's own immune cells modified to attack harmful cells in the body. It is for 15 adults with multiple sclerosis, neuromyelitis optica, autoimmune encephalitis, or stiff person syndrome that have …

This early-stage study tests a new cell therapy called HY001N in 15 adults with relapsed or treatment-resistant autoimmune neurological diseases like neuromyelitis optica. The main goal is to check safety and side effects, while also looking for signs of improvement in disability…

This study looks at whether a quick diagnostic test (BioFire FilmArray) can accurately predict the cause of meningitis or encephalitis in 182 adults. Participants with symptoms like fever, headache, or confusion will have their spinal fluid tested. The goal is to see if the test …

This study tests whether a single dose of amoxicillin before a simple tooth extraction can prevent infections in people with autoimmune rheumatic diseases who are on immune-suppressing medications. Researchers will compare infection rates between those who get the antibiotic and …

This trial investigates whether annual re-screening for tuberculosis infection using a blood test (IGRA) can prevent active TB in people with autoimmune rheumatic diseases who are taking biologic or immunosuppressive medications. Participants who initially test negative for TB ar…

This study will test a new way to offer vaccines to vulnerable patients—those with chronic diseases or weakened immune systems—during hospital visits. Researchers will see if offering, prescribing, and giving vaccines in the hospital increases how many people get vaccinated. The …

This study will follow 1,550 adults with various neurological autoimmune diseases—like multiple sclerosis, myasthenia gravis, and autoimmune encephalitis—to see how these conditions progress and respond to treatments in everyday medical practice. Researchers will measure disabili…
