简要总结
This study aims to preliminarily explore the efficacy and safety of the combination of Obinutuzumab and Zanubrutinib plus Lenalidomide (ZGR) followed by a short cycle of cytarabine and Obinutuzumab in the induction treatment of newly diagnosed mantle cell lymphoma (MCL) . The investigators propose ZGR followed by a short cycle of Obinutuzumab and cytarabine could be an effective first-line treatment for MCL.
详细描述
Based on the clinical need for first-line treatment of MCL, this study proposed to enroll 39 patients with MCL who have not previously received any systemic therapy for MCL. All patients were treated with ZGR regimen for 6 cycles after enrollment, followed by 3 cycles of Obinutuzumab + cytarabine in 28-day cycles. For non-high-risk patients, lenalidomide and Zanubrutinib were used for maintenance; high-risk patients continued Lenalidomide and Zanubrutinib for maintenance following CAR-T cell therapy for 1 year for Lenalidomide and 2 years for Zanubrutinib. The primary endpoint of CRR and secondary endpoints (including ORR, PFS, DoR, and OS) were followed and recorded to explore the efficacy and safety of ZGR followed by a short cycle of Obinutuzumab and cytarabine induction therapy in treatment-naive MCL.

ZGR followed short cycle of Obinutuzumab and Cytarabine
All patients were treated with ZGR regimen for 6 cycles after enrollment, followed by 3 cycles of Obinutuzumab and Cytarabine in 28-day cycles. Obinutuzumab: 1000 mg, intravenous drip, administered on d1, d8 and d15 of the first cycle, and administered on the first day of each cycle starting from the second cycle. Zanubrutinib: 160 mg, bid, continuous oral. Lenalidomide: 20 mg/d, qd, oral, d1-d21.Cytarabine: for young tolerable patients, the dose is 2 g/m2, q12h, intravenous drip, d1-2ND for elderly/intolerant patients, the dose is 500 mg/m2, q12h, intravenous drip, completed 2-3 hours, d1-3. The specific dose is determined by the investigator according to the actual situation of the patient. Zanubrutinib for 2 years combination with Lenalidomide for 1 year was used for maintenance treatment in non-high-risk patients and in high-risk patients after recovery of hemogram 2 months after CAR-T.
