A Clinical Study of Allogeneic CD19/BCMA CAR-T Cells for the Treatment of R/R B-cell Malignant Tumors

Recruiting now · Early Phase 1

Conditions studied: B Cell Lymphoma, Multiple Myeloma

In brief

A single arm, open-label pilot study is designed to determine the safety and efficacy of CD19 and B-cell maturation antigen (BCMA) targeted allogenic CAR-T cells (RN1101) in patients with relapsed/refractory B-cell or plasma cell-derived malignant tumors. 21 patients are planned to be enrolled in the dose-escalation trial. The primary objective of the study is to evaluation of the safety and feasibility of RN1101 for the treatment of relapsed/refractory B-cell or plasma cell-derived malignant tumors. The secondary objective is to evaluate the efficacy of RN1101 for the treatment of relapsed/refractory B-cell or plasma cell-derived malignant tumors. The exploratory objective is to evaluate expansion, persistence and ability of RN1101 to deplete CD19 or BCMA positive cells in patients with relapsed/refractory B-cell or plasma cell-derived malignant tumors.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

Willingness to participate in the trial and provision of signed informed consent.
Patients diagnosed with B-lymphocyte or plasma cell-derived malignancies as per the 2017 revised WHO criteria, including acute B-lymphoblastic leukemia (B-ALL), and mature B-cell lymphomas such as diffuse large B-cell lymphoma (DLBCL), follicular lymphoma (FL), marginal zone lymphoma (MZL), small lymphocytic lymphoma/chronic lymphocytic leukemia (SLL/CLL), mantle cell lymphoma (MCL), multiple myeloma (MM), etc.
Refractory or recurrent B-lymphocyte or plasma cell-derived malignancies, defined as failure to achieve complete remission after standard treatment, or relapse during follow-up after achieving remission with first-line or salvage therapy.
Patients with B-cell acute lymphoblastic leukemia (ALL) who have achieved hematologic remission but have persistent minimal residual disease (MRD).
According to the revised International Working Group (IWG) criteria, relapsed/refractory lymphoma patients must have at least one measurable lesion with a longest diameter ≥1.5 cm.
18 Years and older, regardless of gender.
An expected survival of ≥12 weeks.
Serum total bilirubin level < twice the upper limit of normal, serum creatinine level < upper limit of normal, serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) < three times the upper limit of normal.
Absolute neutrophil count ≥0.5×10⁹/L, platelets ≥20×10⁹/L; for B-lymphocyte malignancies with definitive bone marrow involvement, no requirements for neutrophil and platelet counts.
ECOG performance status of 0 - 2.
Left ventricular ejection fraction (LVEF) ≥50% and no pericardial effusion.
At least 2 weeks have passed since the last treatment (radiotherapy, chemotherapy, monoclonal antibody therapy, or other treatments).

You may not qualify if…

Known allergies, hypersensitivity, intolerance, or contraindications to CD19/BCMA allogenic CAR-T or any components of the trial drugs (including fludarabine, cyclophosphamide, and rituximab), or a history of severe allergic reactions.
Recurrence after allogeneic hematopoietic stem cell transplantation with active graft - versus - host disease (GVHD) requiring steroid or immunosuppressive therapy.
Severe active infection.
Acquired or congenital immunodeficiency.
New York Heart Association (NYHA) Class Ⅲ or Ⅳ heart failure.
History of epilepsy or other central nervous system diseases.
Lymphoma with extranodal involvement of the brain, lungs, or gastrointestinal tract.
Other primary cancers, except:
Non-melanoma skin cancer (e.g., basal cell carcinoma) cured by resection.
Carcinoma in situ (e.g., cervical, bladder, or breast cancer) cured.
Systemic high-dose steroids within 2 weeks before treatment.
Pregnant, breastfeeding, or plans to become pregnant within 6 months.
Participation in another clinical trial within the past month.
Any situation the investigator deems may raise risks or interfere with trial results.
