R-CHOP regimen is the first-line therapy in DLBCL which greatly improved the efficacy of diffuse large B-cell lymphoma (DLBCL) and achieved good long-term survival. However, among DLBCL patients treated with R-CHOP, EBV+ had a lower 5-year OS than EBV- patients (65% vs 82%). For primary mediastinal large B-cell lymphoma (PMBCL), although the initial treatment has a better prognosis than DLBCL, there are still 10% to 30% of PMBCL patients with primary refractory or relapsed disease, and the prognosis is poor.~Zanubrutinib combined with Tislelizumab has been proved efficient in relapsed or refractory NHLs, with ORR rate 37%, CR rate of 16.7%. This phase II, prospective, open-label, single-arm study will evaluate the efficacy and safety of Zanubrutinib combined with Tislelizumab in the treatment of relapsed/refractory primary mediastinal large B-cell lymphoma and Epstein-Barr Virus-positive diffuse large B-cell lymphoma.
The study is to investigate the safety and efficacy of Zanubrutinib combined with Tislelizumab in the treatment of relapsed/refractory primary mediastinal large B-cell lymphoma and Epstein-Barr Virus-positive diffuse large B-cell lymphoma.
