CD19 CAR-T Therapy for Patients With Newly Diagnosed High-risk Large B-cell Lymphoma

This study is indicated for patients with CD19+ newly diagnosed high-risk large B-cell lymphoma. This study is an investigator-initiated, single-center, single-arm phase II clinical trial of rituximab, lenalidomide, and zanubrutinib (ZR2) with Sequential CAR-T cell as first-line therapy for newly diagnosed high-risk LBCL. Primary objective is to explore the efficacy and also safety.

• Confirmed CD19 and CD20 postive expressions in lymphoma cells
• ECOG score 0-2;
• Total bilirubin ≤ 51 umol/L, ALT and AST ≤ 3 times of upper limit of normal, creatinine ≤ 176.8 umol/L;
• Echocardiogram shows left ventricular ejection fraction (LVEF) ≥50%;
• No active infection in the lungs, blood oxygen saturation in indoor air is ≥ 92%;
• Estimated survival time ≥ 3 months;
• Patients or their legal guardians volunteer to participate in the study and sign the informed consent.
