PD1 Antibody and Lenalidomide as a Treatment for EBV-HLH or CAEBV


The present study was a prospective one-arm clinical study, in which EBV-HLH/chronic active EBV infection patients were selected as the main subjects to evaluate the effect of PD-1 antibody and lenalidomide regimens on ebv-dna and safety.
