About this study

The goal of this study is to evaluate the safety and efficacy of CD19 CAR T cells in the treatment of Refractory Autoimmune Diseases

Read the detailed description

This is a single-center, open-label, single-arm, dose-escalation trial. In this study, we will recruit seven kinds of refractory autoimmune diseases including moderate-to-severe Systemic lupus erythematosus (SLE), refractory Pemphigus, refractory Idiopathic inflammatory myopathy (IIM), Systemic sclerosis (SSc), Refractory ANCA-Associated Vasculitis/Nephritis,refractory Rheumatoid arthritis(RA) and moderate-to-severe refractory Psoriasis.

Patients with Refractory Autoimmune Diseases will receive CD19 CAR T cells. The primary objective is to evaluate the safety and efficacy of CD19 CAR T cell therapy in subjects with Refractory Autoimmune Diseases and to determine the optimal biological dose (OBD) in phase I and to learn about the efficacy CD19 CAR T-cell therapy in patients with Refractory Autoimmune Diseases in phase II.

The primary endpoint is to evaluate the incidence and severity of cytokine release syndrome and severe neurotoxic adverse events within 28 days after CAR-T cell infusion.A total number of 3o subjects will be enrolled.

    • Almost complete clearance: 90 - 100 % improvement in PASI.
    • Effective response: 75 - 90 % improvement in PASI.

  14. ANCA-associated vasculitis/nephritis:Birmingham Vasculitis Activity Score (BVAS)

    ANCA-associated vasculitis/nephritis: According to the 2024 KDIGO Clinical Practice Guideline for the Management of ANCA-Associated Vasculitis, disease outcomes will be evaluated with the Birmingham Vasculitis Activity Score (BVAS).

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing CD19 CAR-T cells in people with Autoimmune Diseases, run by Hebei Senlang Biotechnology Inc., Ltd. at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 45 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 8 Sep 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Huirui Wang, M.D. (+86-0379-63307832, wanghuirui7873@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Phase I:Cytokine Release Syndrome (CRS) (time frame: 28 days post infusion). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Sep 2025.
