About this trial

This study is an open-label, single-arm, dose-escalation and dose-expansion study to evaluate the safety, maximum tolerated dose, pharmacokinetic profile in the body after infusion of RS001 injection, and preliminary efficacy in subjects with CD19-positive relapsed/refractory B-cell malignancies (BCM).

Eligibility criteria

Qualifiers

Voluntarily sign an ICF and expect to complete the subsequent follow-up.

Aged 18 to 75 years (including cut-offs), regardless of gender.

. B-cell non-Hodgkin's lymphoma diagnosed as CD19-positive by cytology or histopathology according to WHO 2022 criteria, including pathologically confirmed (1) diffuse large B-cell lymphoma, non-specific type (DLBCL, NOS); (2) follicular lymphoma histopathologically graded as grade 3b (FL3b); (3) follicular lymphoma with diffuse large B-cell transformation; (4) primary mediastinal large B-cell lymphoma (PMBCL); (5) high-grade B-cell lymphoma (HGBCL).

Definition of refractory: No response to second-line or more therapy: The best efficacy of last therapy is PD or SD (SD requires at least 2 cycles of treatment); Recurrence (must have biopsy-proven recurrence) or progression within 12 months of autologous stem cell transplantation (ASCT) . If salvage therapy, no response to last therapy (SD or PD).

Disqualifiers

Any unstable systemic disease: including but not limited to active infection (other than local infection), unstable angina, cerebrovascular accident or transient ischaemia (within 6 months prior to screening), myocardial infarction (within 6 months prior to screening), myocardial infarction (within 6 months prior to screening), New York Heart Association class III or IV cardiac insufficiency, refractory hypertension (refractory hypertension is defined as blood pressure that has not reached standard after >1 month of reasonably tolerable treatment with ≥3 antihypertensive drugs (including diuretics) at adequate doses based on lifestyle improvement or blood pressure that is not effectively controlled with ≥4 antihypertensive drugs), severe cardiac arrhythmias requiring pharmacologic treatment, hepatic arrhythmias, liver diseases, kidney diseases or metabolic disorders;

Patients with B-cell non-Hodgkin's lymphoma with active central nervous system invasion.

Patients with positive hepatitis B surface antigen (HBsAg) or hepatitis B core antibody (HBcAb) and peripheral blood hepatitis B virus (HBV) DNA titres not within the normal reference range, positive hepatitis C virus (HCV) antibody and peripheral blood HCV RNA ,positive for human immunodeficiency virus (HIV), or positive for cytomegalovirus (CMV) DNA, or positive syphilis test.
