The purpose of the study is to determine the feasibility, safety and efficacy of administering rapidly-generated donor-derived pentavalent-specific T cells (Penta-STs) to mediate antiviral and antifungal activity in hematopoietic stem cell transplant (HSCT) recipients with AdV, EBV, CMV, BKV or Aspergillus fumigatus (AF) infection/ reactivation or with active disease.


Reconstitution of anti-viral and antifungal immunity by donor-derived antigen-specific T cells has shown promise in preventing and treating infections with CMV, or/and EBV, or/and AdV or/and BKV, HHV6 or/and AF post-transplant. However, the broader implementation of T cell immunotherapy using conventional protocols is limited and until today it was practically impossible for Greece by the cost, the complexity and the time required for virus-specific T cells (VSTs) production and by the antigenic competition between different antigens, which limits the spectrum of viruses that can be targeted in a single T cell product.

In this trial, the investigators will evaluate the feasibility, safety and efficacy of donor-derived Penta-STs infusion to allogeneic HSCT recipients with confirmed AdV, EBV, CMV, BKV and AF infection.
