Clinical Study of HiR+X Therapy for Newly Diagnosed Elderly Patients with DLBCL Intolerant to Chemotherapy

Summary

To explore the application of HiR (Zebtorizumab, Lenalidomide) + X (targeted drug) guided by NGS molecular typing, the aim is to assess the therapeutic efficacy and safety in newly diagnosed unfit or frail elderly patients with DLBCL aged ≥70 years, and to investigate the genetic subtypes that may benefit from HiR-X.

5. Previously untreated, newly diagnosed patients;
6. Cardiac, hepatic, and renal function: creatinine \< 2 times the upper limit of normal (ULN); ALT (alanine aminotransferase) / AST (aspartate aminotransferase) \< 2.5 x ULN; total bilirubin \< 2 x ULN;
7. At least one measurable lesion;
8. Intolerance to standard CHOP chemotherapy regimen or unwillingness to receive chemotherapy;
9. Sufficient understanding and voluntary signing of the informed consent form.
