Overview
This is a prospective, single-arm, multicenter, phase II clinical trial to evaluate the efficacy and safety of orelabrutinib combined with the R-CHOP (rituximab, cyclophosphamide, vincristine, doxorubicin, and prednisone) regimen as first-line treatment in CD5-positive diffuse large B-cell lymphoma (DLBCL) patients.
Description
The purpose of this phase II clinical trial is to evaluate the efficacy and safety of orelabrutinib in combination with R-CHOP for untreated CD5-positive DLBCL patients.
The induction phase consisted of 6 cycles of orelabrutinib in combination with R-CHOP (orelabrutinib added from the second cycle), followed by 2 cycles of rituximab + orelabrutinib, for a total of 8 treatment cycles. After 8 cycles of induction therapy, if the response is assessed as complete remission (CR), maintenance therapy with orelabrutinib will be conducted.
The primary endpoint is the 2-year event-free survival (EFS) rate.
