    EBV Reactivation and Lymphomagenesis: More Questions than Answers. (PubMed, Curr Hematol Malig Rep)
    These include immunosuppression reduction, nucleoside analogs, HDAC inhibitors, EBV-specific cytotoxic T-lymphocytes (CTLs), and monoclonal antibodies, such as rituximab. There is currently an open clinic trial combining the use of a HDAC inhibitor, nanatinostat, and ganciclovir to treat refractory/relapsed EBV lymphomas. Another novel therapy includes tabelecleucel, which is an allogenic EBV-directed T-cell immunotherapy that was approved by the European Medicines Agency, but is currently only available in the US for limited use in relapsed or refractory EBV-positive PTLD. Further research is needed to establish EBV monitoring protocols in high-risk populations, such as those with autoimmune disease, cancer, HIV, or receiving immunosuppressive therapy. Additionally, standardized treatments for both the prevention of EBV reactivation in high-risk populations and treatment of EBV reactivation and lymphoproliferation need to be established.

    [VIRTUAL] Oral Nanatinostat (Nstat) and Valganciclovir (VGCV) in Patients with Recurrent Epstein-Barr Virus (EBV)-Positive Lymphomas: Initial Phase 2 Results (ASH 2020)
    For DLBCL (n=6), ORR/CR was 66%/33% (both CRs were in pts refractory to first-line R-CHOP). Co-administration of oral Nstat with VGCV has a favorable safety profile, may be suitable for combination with additional agents, and shows promising efficacy in pts with a variety of R/R, heavily pre-treated EBV+ lymphomas, the majority of whom were lacking therapeutic options. Preliminary data suggests that this regimen is highly active in EBV+ T/NK-NHL pts who are refractory to standard therapies, including ASCT (Table 1), and promising in EBV+ DLBCL. Thus far, no apparent correlation was noted between degree of EBER positivity in pre-study tumor biopsies and ORR.
