Details and patient eligibility

About

The objective of exploring the application of CHiR is to evaluate its therapeutic efficacy and safety in newly diagnosed elderly patients with diffuse large B-cell lymphoma (DLBCL) aged 70 and above, and to investigate the genetic subtypes that may benefit from CHiR. The primary endpoint is the complete remission rate (CRR) at the end of 8 cycles.

Enrollment: 30 estimated patients

Sex: All

Ages: 70 to 100 years old

Volunteers: No Healthy Volunteers

Experimental group

Description:

The combined regimen of chidamide, zanubrutinib, and lenalidomide (CHiR) is employed to treat elderly patients with double-expressor lymphoma. This study aims to explore the efficacy and safety of this regimen in newly diagnosed elderly patients with diffuse large B-cell lymphoma (DLBCL) who are intolerant to chemotherapy.
