The study will start with an initial 21-days of induction therapy with orelabrutinib and rituximab，following imaging examinations to evaluate response rates. Then treatment with 6 cycles chemoimmunotherapy (R-CHOP-like) either alone or in combination with orelabrutinib will depend on response during induction phase. Each cycle is 21 days.
The purpose of this study is to evaluate the efficacy and safety of orelabrutinib combined with rituximab，followed by orelabrutinib combined with R-CHOP-like regimen for newly diagnosed untreated Non-GCB DLBCL Patients
