Telitacicept for Refractory Chronic Inflammatory Demyelinating Polyneuropathy
China76 participantsStarted 2025-09-26
Plain-language summary
This multicenter, randomized, controlled trial aims to evaluate the efficacy and safety of Telitacicept in patients with refractory chronic inflammatory demyelinating polyneuropathy (CIDP). Eligible patients will be randomly assigned to receive either conventional therapy alone or Telitacicept plus conventional therapy for 24 weeks. Efficacy will be assessed using CIDP-related clinical and functional measures, including the Inflammatory Neuropathy Cause and Treatment (INCAT) disability score, Inflammatory Rasch-built Overall Disability Scale (I-RODS), Medical Research Council (MRC) sum score, grip strength, and the Timed Up and Go (TUG) test. Safety will be evaluated by monitoring adverse events, including their onset, duration, clinical manifestations, and management.

Exclusion criteria
. Progressive neurological disease unrelated to CIDP.
. Limb numbness or weakness caused by other etiologies, including but not limited to hereditary demyelinating neuropathy, neuropathy secondary to infection or systemic disease, diabetic neuropathy, drug- or toxin-induced neuropathy, multifocal motor neuropathy, polyneuropathy associated with IgM monoclonal gammopathy, POEMS syndrome, cerebral infarction, acute myelitis, multiple sclerosis, neuromyelitis optica spectrum disorder, or other conditions that may cause limb numbness or muscle weakness.
. Active hepatitis or severe hepatic dysfunction, defined as liver function test values greater than two times the upper limit of normal. Participants who are positive for hepatitis B surface antigen (HBsAg) will be excluded. Participants who are positive only for hepatitis B core antibody (HBc-Ab) must undergo quantitative HBV-DNA testing and will not be excluded if the result is negative.
. Severe renal impairment, including acute kidney injury or chronic kidney disease, or serum creatinine clearance \<60 mL/min calculated using the Cockcroft-Gault equation.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
