About this study

Official title: An Open-label Phase I/IIa, Multicentre, Interventional Single-arm Trial of MB-CART19.1 in Patients With Refractory SLE

This is a phase l/ll open-label, multicentre, interventional single-arm trial of MB-CART19.1 in patients with refractory SLE systemic lupus erythematosus. In the phase I part, a maximum of n=12 patients will be treated in a maximum of 3 dose levels.

In the phase IIa part, a maximum of n=17 will be treated (n=10 patients in a 1st stage + n=7 patients in a 2nd stage). This includes the patients from the phase I part treated on the recommended dose level.

Read the detailed description

Patients will be treated in cohorts of 3. After each cohort, the Safety Monitoring Board (SMB) will meet to assess whether the next higher dose level can be opened.

The follow-up of the patients will be performed in 3 steps:

  • Until day 28 after treatment, the patients will be followed up closely by monitoring vital functions and lab parameters for signs of AEs and DLTs. Blood samples for the determination of persistence and phenotype of infused CAR+ cells will be taken. B cell aplasia in peripheral blood will be determined together with other secondary and exploratory biomarkers, response will be assessed and AEs will be documented.
  • In the second follow-up phase until 1 year, blood samples for the determination of persistence and phenotype of infused CAR+ cells will be taken, B cell aplasia will be determined, response will be assessed and AEs will be documented until end of week 12, afterwards serious AEs (SAE) and AEs of special interest (AESI) will be documented, serious adverse reactions (SAR)/AESI will be reported.
  • All patients irrespective of the clinical response will be followed up then for 1 more year or until the patient is lost to follow-up or has died. After completion of this last follow-up phase, patients will be rolled over to a subsequent follow-up observation for up to further 13 years.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing MB-CART19.1 in people with SLE - Systemic Lupus Erythematosus, run by Miltenyi Biomedicine GmbH at 3 sites in Germany.

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 17 inclusion and 32 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: looking for participants now, as of the sponsor's last update on 26 Nov 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Germany. 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 Clinical Trial Manager (+4922048306820, clinicaltrials.gov@miltenyi.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Phase I: Determination of the recommended dose for phase IIa out of 3 dose levels (time frame: Until day 28 after infusion of MB-CART19.1). 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 26 Nov 2025.
