About this trial

The investigational product is designed to effectively combat B cells in patients with autoimmune diseases. Autologous T cells enriched with CD4/CD8 are genetically engineered using a lentiviral vector to express chimeric antigen receptors (CARs) that target the CD19 antigen on the cell surface of B cells and their precursors. During treatment, patients undergo leukapheresis, lymophodepleting chemotherapy and administration of the expanded CD19-CAR-transduced T cells.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Subjects must understand and voluntarily sign an informed consent form including written consent for data protection,

Adults aged ≥ 18 years at time of consent,

Adequate renal (eGFR > 30 ml/min/m2), liver (no Child Pugh C), heart (at worst NYHA III, EF > 30%) and pulmonary (FV and DLCO > 30%) function,

Male subjects unless surgically sterile, must agree to use two acceptable methods for contraception (e.g. spermicide and condom) during the trial and refrain from fathering a child starting from the time of signing the Informed Consent Form (ICF) until 12 months after dosing of the IMP,

Disqualifiers

Clinically suitability for a less burdensome and/or approved therapeutic approach, as judged by the investigator

ANC < 1.000/mm3, ALC < 500/mm3 or hemoglobin < 8g/dl, absolute CD3+ T cell count < 100/μl,

Uncontrolled severe concomitant disease, such as cancer (except basal or squamous cell skin cancer) and diabetes mellitus,

Severely impaired renal (eGFR ≤ 30 ml/min/m2), liver (Child Pugh C), heart (NYHA IV, EF ≤ 30%) and pulmonary (FV and DLCO ≤ 30%) function,

Trial outcomes

Primary outcomes

1

To assess the safety of anti-CD19 CAR T cell therapy in subjects with active B-driven autoimmune disease (SLE, SSc and DM/PM).

Incidence and grading of severity (graded 0-4) of Cytokine Release Syndrome (CRS) and of CAR T cell-associated neurotoxicity (ICANS) within the first 4 weeks after ATMP administration.

Time frame
up to d 28

Secondary outcomes

1

Clinical efficacy SSc

Overall Response Rate (ORR) at week 24 measured by specific disease activity composite indexes, each of them validated for the specific disease: SSc: No progression of interstitial lung disease with worsening of FVC1 (\>10 percentage) or worsening of FVC1 (5-10 percentage) plus increase in respiratory symptoms or worsening of FVC1 (5-10 percentage) plus progression of high-resolution computed tomography changes after 24 weeks.

Time frame
at week 24
2

Clinical efficacy SLE

Overall Response Rate (ORR) at week 24 measured by specific disease activity composite indexes, each of them validated for the specific disease: SLE: Fulfillment of DORIS remission criteria of SLE at week 24.

Time frame
at week 24
3

Clinical efficacy DM

Overall Response Rate (ORR) at week 24 measured by specific disease activity composite indexes, each of them validated for the specific disease: DM: 2016 ACR/EULAR moderate or major response.

Time frame
at week 24
4

Cellular response

* amount of CAR T cells in the peripheral blood (cells/µl) * amount of B cells in the peripheral blood (cells/µl) * expansion of CAR T cells in the patient over time in cells/µl

Time frame
up to week 24
