The Efficacy and Safety of Zanubrutinib, Rituximab and Lenalidomide (ZR2) Versus Rituximab Combined With Low-dose CHOP (R-miniCHOP) in the Treatment of Unfit or Frail de Novo Diffuse Large B-cell Lymphoma Patients Aged Older Than or Equal to 70 Years: A Multicenter, Prospective, Randomized, Open-label, Controlled Trial
A multicenter, prospective, randomized, open-label, controlled trial to evaluate the efficacy and safety of zanubrutinib, rituximab and lenalidomide (ZR2) versus rituximab combined with low-dose CHOP (R-miniCHOP) in the treatment of unfit or frail de novo diffuse large B-cell lymphoma patients aged older than or equal to 70 years
⁃ Patients must satisfy all of the following criteria to be enrolled in the study:
• Histologically-confirmed diffuse large B-cell lymphoma (without central nervous system involvement)
• Eastern Cooperative Oncology Group performance status 0-3
• Aged ≥ 80 years old or aged 70-79 with comprehensive geriatric assessment stratified as unfit or frail
• International normalized ratio and activated partial thromboplastin time are both 1.5 times lower than the upper limits of normal (ULN).
• At least 1 measurable site of disease (defined as lymph nodes with the long diameters longer than 1.5cm, or extra-nodal sites with the long diameters longer than 1.0cm; meanwhile, any lesion site with at least 2 measurable vertical diameters)
• Life expectancy of at least 3 months determined by researchers
• The patient or his or her legal representative must provide written informed consent prior to any special examination or procedure for the research.
• Anti-lymphoma drugs have not been used before (except glucocorticoids).
