Bone Marrow Transplant Infection Clinical Trial
Official title:
Administration of Rapidly Generated Multipathogen-specific T-Lymphocytes for the Treatment of AdV, CMV, EBV, BKV and Aspergillus Fumigatus Infections Post Allogeneic Stem Cell Transplant
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. ;
