PHASE2

Zanubrutinib Combined With G-CVP in Previously Untreated FL

Sponsor: Cancer Institute and Hospital, Chinese Academy of Medical Sciences

View on ClinicalTrials.gov

Summary

The goal of this clinical trial is to learn the efficacy and safety of zanubrutinib in combination with G-CVP in previously untreated follicular lymphoma patients The main questions it aims to answer are: (1) Efficacy and safety of patients receiving zanubrutinib, obinutuzumab combined with cyclophosphamide, vincristine, and prednisone (CVP) regimen. (2) The difference in efficacy of patients with different minimal residual disease (MRD) status after treatment. Participants will receive zanubrutinib combined with G-CVP, maintenance therapy will be determined by the MRD status after treatment.

DRUG

zanubrutinib, obinutuzumab,combined with CVP

Zanubrutinib (160 mg, twice daily \[bid\]), obinutuzumab (1000 mg on cycle 1 \[C1\], days 1, 8, and 15; on cycle 2 - 6 \[C 2-6\], day 1), cyclophosphamide (750 mg/㎡ on day 1), vincristine (1.4 mg/㎡, maximum dose 2 mg on day 1), and prednisone tablets (40 mg/㎡ once daily \[qd\] orally on days 1-5) were used every 21 days as a treatment cycle. Six cycles of treatment were completed, and the efficacy was reviewed every two cycles. Patients with PD were excluded from the group. MRD was detected after six cycles. If MRD was negative, routine maintenance therapy was performed (obinutuzumab 1000 mg once every 8 weeks, a total of 12 times). If MRD was positive, Zanubrutinib (160 mg, continuous bid) was added to the conventional maintenance therapy for 12 months.
