E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Patients undergoing allogeneic HSCT undergo weekly screening for HAdV and CMV PCR. In case of viraemia ≥ 100 copies/ml PB preemptive antiviral with either Gancyclovir or Cidofovir conform to the local HSCT-infection-SOPs. In case of increasing viral load despite adequte virostatic treatment for two weeks, the administration of donor derived (or receipient derived in case of donor CMV negativity and receipient positivity before HSCT) virus specific T cells is foreseen
|
Patienten nach allogener Stammzelltransplantation werden wöchentlich auf CMV und ADV gescreent und erhalten bei Virämie die entsprechende virostatische Therapie. in einigen Fällen ist die Virusinfektion trotz adäquater virostatischer Therapie progredient. In diesem Fall ist eine zusätzliche Therapie mit Virus-spezifischen Spender-T-zellen (bzw. Virus-spezifischen autologen T-Zellen, wenn vor HSCT beim Empfänger vorhanden) vorgesehen. |

E.1.1.1 | Medical condition in easily understood language |
patients after allogeneic HSCT with increasing viral load inspite of virostatic treatment for two weeks may reiceive virus-specific T cells |
Patienten nach allogener Stammzelltransplantation mit steigender Viruslast trotz virostatischer Behandlung für zwei Wochen können virus-spezifische T-Zellen erhalten |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
1. Primary:
Evaluation of feasibility, safety and potential side effects of short-term expanded HAdV- and CMV-specific T- cells (seVirus-T-cells) in patients with HAdV and/or CMV viraemia not responding to antiviral therapy after allogeneic HSCT. • Acute toxicity (Grade III-IV) of seVirus-T-cell infusion within 48 hours from infusion
• De novo acute GvHD > Gr II or increase of pre-existing GvHD more than 1 grade from 2 weeks post infusion until 8 weeks post infusion • incidence of graft rejection
|
Erfassung der Verträglichkeit bzw. Inzidenz der akut-Toxizität, der akuten GvHD Gr III-IV und der Graft-Abstoßung nach der Gabe von Virus-spezifischen-T-Zellen |
|
E.2.2 | Secondary objectives of the trial |
2. Secondary:
Detection of virus-specific T-cells within 8 weeks after T-cell therapy. Measurement of the viral load following the infusion of seVirus-T-cells
Correlation of the presence of virus-specific T-cells with partial reduction (>1 log viral copies /ml blood) or complete clearance of viral load.
Tracking of the infused seVirus-T-cells by NGS of the TCRs
|
Detektion von virus-spezifischen T-Zellen innerhalb von 8 Wochen nach verabreichter Zelltherapie. Messung der Viruslast nach verabreichter Se-Virus-T-Zell Infusion.
Korrelation der vorhandenen e-Virus-T-Zellen mit der Reduktion oder Beseitigung der Viruslast.
Tracking der infundierten e-Virus-T-Zellen via NGS des TCR.
