Brief Summary

This study aims to evaluate the long-term efficacy of BTK inhibitor Zanubrutinib monotherapy , sequential Zanubrutinib combined (Fludarabine, cyclophosphamide and rituximab /bendamustine and rituximab)FCR/BR regimen by a limited period of treatment for the newly diagnosed Chronic Lymphocytic Leukemia (CLL) or Small Lymphocytic Lymphoma (SLL). The investigators propose this combination will improve the MRD negative rate of patients with CR/CRi after treatment was significantly higher than that of FCR chemotherapy can be a time-limited regimen which will reduce the life-time therapy and benefit the patients.

Detailed Description

The investigators designed timed FCR/BR treatment for BTK inhibitor Zanubrutinib monotherapy after continuous remission, which shortened the treatment time, deepened the depth of remission, and enabled some patients to achieve deep remission (MRD negative), and realized long-term survival after drug withdrawal. Treatment regimens: Zanubrutinib monotherapy for 12 months followed by 4 courses of immunochemotherapy with FCR or BR. Cohort 1 was designed to apply FCR for patients aged 65 years or younger who could tolerate FCR. Cohort 2 was designed to apply BR in patients older than 65 years or unable to tolerate FCR.

Conditions

Study Groups

ZFCR regimen

Patients aged 65 years or younger who can tolerate FCR： Patients in this group will receive zanubrutinib monotherapy for 12 months, then receive 4 cycles of zanubrutinib, fludarabine, cyclophosphamide and rituximab(ZFCR). Efficacy evaluation and MRD test of peripheral blood and bone marrow were performed at the 17th cycle after 16 cycles to obtain study end point data. Patients with CR/CRi and MRD negative could stop taking zanubrutinib, and other patients could stop taking zanubrutinib or continue treatment. Follow-up and efficacy assessment were conducted every three months.

Group Type: EXPERIMENTAL

Zanubrutinib, Fludarabine, cyclophosphamide and rituximab

Intervention Type: DRUG

Patients aged 65 years or younger who can tolerate FCR.

ZBR regimen

For patients older than 65 years or who cannot tolerate FCR regimens: Patients in this group will receive zanubrutinib monotherapy for 12 months, then receive 4 cycles of bendamostine and rituximab(BR). Efficacy evaluation and MRD test of peripheral blood and bone marrow were performed at the 17th cycle after 16 cycles to obtain study end point data. Patients with CR/CRi and MRD negative could stop taking zanubrutinib and other patients could stop taking zanubrutinib or continue treatment.

Exclusion Criteria

• 1. Have been diagnosed or treated for malignancies other than CLL (including active CNS lymphoma) within the past year
