Can a One-Time cell therapy reset the immune system in autoimmune disease?
NCT ID NCT07778446
First seen Aug 21, 2026 · Last updated Aug 21, 2026
Summary
This trial is testing an experimental treatment called CRT-402 for people with severe autoimmune diseases like lupus, scleroderma, and myositis that haven't improved with standard therapies. CRT-402 is a type of CAR-T cell therapy given by infusion that aims to deplete certain immune cells (B cells) and potentially reset the immune system. The study will evaluate the safety, tolerability, and preliminary effectiveness of this approach in about 34 adults.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- CRT-402, an in vivo CD19-targeted CAR-T cell therapy
- What this could lead to
- If successful, this could lead to a one-time treatment that resets the immune system, potentially offering long-term remission for people with severe autoimmune diseases.
- What could go wrong
- This is an early-stage trial, so safety and effectiveness are not yet proven. There are risks of serious side effects like cytokine release syndrome and neurotoxicity.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age 18 years or older. * Diagnosis of active, refractory systemic lupus erythematosus, systemic sclerosis, or idiopathic inflammatory myopathy meeting established classification criteria, with inadequate response or intolerance to standard therapy. * Adequate renal, hepatic, cardiac, and pulmonary function per protocol-defined criteria. * Participants of reproductive potential must agree to use protocol-specified contraception during the study and for a defined period after dosing. * Females of childbearing potential must have a negative pregnancy test before treatment. * Must be willing and able to attend study visits and follow all study requirements. Exclusion Criteria: * Clinical suitability for a less burdensome and/or approved therapeutic approach, as judged by the Investigator, * Any medical condition or laboratory abnormality that, in the Investigator's judgment, would place the participant at unacceptable risk or confound interpretation of study data, * Prior Cluster of differentiation 19 (CD19)-directed, cell, or gene therapy, * History of bone marrow/ hematopoietic stem cell or solid organ transplantation, * Active or inadequately treated infection, including Human immunodeficiency (HIV), hepatitis B or C, or tuberculosis, * Pregnancy or lactation.
