Efficacy and Safety of BV With Tislelizumab for the Treatment of CD30+ Relapsed/Refractory NK/T-cell Lymphoma

This is a single-arm, open-label, multicenter, phase 2 study designed to evaluate the efficacy and safety of brentuximab vedotin combined with PD-1 inhibitor tislelizumab in Chinese patients with relapsed/refractory CD30+ NK/CL. Brentuximab vedotin will be administered as 1.8 mg/kg IV infusion on Day 1 of each 3-week cycle. PD-1 inhibitor tislelizumab will be administered as 200 mg on Day 1 of each 3-week cycle. Patients will receive maximum of 8 cycles if they do not meet the criteria for removal from the study. Patients will be assessed for overall response using the Revised Response Criteria for Malignant Lymphoma (Lugano 2014). Dedicated computed tomography (CT) scans (neck, chest, abdomen, and pelvis) will be performed at Baseline and at Cycles 2, 4 and 8, and positron emission tomography (PET) scans will be performed at Baseline and at Cycles 4 and 8. No additional PET scanning is required beyond Cycle 8 unless clinically indicated (for example, suspected of disease progression). The disease symptoms will be assessed at Baseline and on Day 1 of each cycle. Patients may continue study treatment until the sooner of disease progression, unacceptable toxicity, or completion of 8 cycles. Patients who discontinue study treatment for any reason other than withdrawal of consent will have safety follow-up assessments through 30 days after the last dose of 、study drug (end of treatment [EOT]). Patients who discontinue study treatment with stable disease (SD), responses and progression disease (PD) will be followed for 1-year PFS rate and 1-year OS rate. The CT scan, PET-CT and laboratory examination will be followed based on clinical practice. The study will be closed when all patients enrolled have completed the required follow-up.Toxicity will be evaluated according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE), version 5.0 Laboratory values, vital signs, and electrocardiograms (ECGs) will be obtained to evaluate the safety and tolerability of study treatment.
