Application of PD-1 Inhibitors Combined With Tenofovir, Chidamide and Lenalidomide in the Treatment of EBV-associated Diseases.

This study involves a four-drug combination regimen consisting of a PD-1 inhibitor, tenofovir, chidamide, and lenalidomide for the treatment of EBV Infectious diseases, aiming to inhibit viral replication and restore immune function through multiple mechanisms. The intervention includes not only pharmacological treatment but also pre-treatment assessments (such as EBV-DNA load, immune status, cardiac and renal function), efficacy monitoring during treatment (e.g., ORR, changes in EBV-DNA), and post-treatment follow-up for safety and survival outcomes (including OS, PFS, and adverse events), in order to comprehensively evaluate the clinical value and feasibility of this combination therapy.
