This single-arm, open-label pilot study will assess the safety and efficacy of RN1701, a bispecific CD19/CD20-targeted allogeneic CAR-T-cell product, in patients with relapsed or refractory B-cell lymphoma. Up to 19 participants will be enrolled in a conventional 3 + 3 dose-escalation scheme. The primary objective of the study is to evaluate the safety and feasibility of RN1701 for the treatment of relapsed/refractory B-cell lymphoma. The secondary objective is to evaluate the efficacy of RN1701 for the treatment of relapsed/refractory B-cell lymphoma. The exploratory objective is to evaluate the expansion, persistence, and ability of RN1701 to deplete CD19- and/or CD20-positive cells in patients with relapsed/refractory B-cell lymphoma.

Age 18-75 years; either sex.
ECOG performance status 0-1.
Histologically confirmed large B-cell lymphoma, follicular lymphoma, mantle-cell lymphoma, or indolent lymphoma transformed to DLBCL; CD19 and/or CD20 positive.
Malignancy that received curative therapy and has shown no evidence of active disease for ≥2 years before enrolment; or
Adequately treated non-melanoma skin cancer with no current evidence of disease.
CNS prophylaxis (e.g., intrathecal methotrexate and/or cytarabine) within 7 days;
Cytotoxic chemotherapy or radiotherapy within 14 days;
Single group
RN1701 injection
Biological/VaccineRN1701 injection is a bispecific CD19/CD20-targeted allogeneic CAR-T. A single infusion of CAR-T cells will be administered intravenously
Toxicity and adverse event grading after RN1701 treatment
all toxicities and AEs will be assessed according to the National Cancer Institute CTCAE v5.0
CRS grading after RN1701 treatment
CRS will be graded using the Lee DW et al. CRS grading scale. Grade 1: Fever, mild symptoms, manageable with supportive care Grade 2: Moderate symptoms (eg, hypotension, hypoxia), requires intervention (eg, intravenous fluids, antipyretics) Grade 3: Severe symptoms (eg, multiorgan involvement), requires corticosteroids and tocilizumab Grade 4: Life-threatening, requires intensive care unit (ICU) care and urgent interventions
Overall response rate (ORR =CR + PR) of patients receive RN1701 treatment
according to the Lugano criteria and CSCO guidelines
Disease control rate (DCR=CR +PR +SD) of patients receive RN1701 treatment
according to the Lugano criteria and CSCO guidelines
Assessment includes contrast enhanced CT of head/neck, chest, abdomen,and pelvis, plus whole-body PET-CT
Tumor measurements and evaluations must be performed with the same technique used at baseline
