Multivirus-specific T-cell Transfer Post SCT vs AdV, CMV and EBV Infections

Exclusion Criteria13

• Patient with acute GvHD \> grade II or extensive chronic GvHD at the time of IMP transfer
• Patient receiving steroids (\>1 mg/kg BW Prednisone equivalent) at Screening.
• Therapeutic donor lymphocyte infusion (DLI) from 4 weeks prior to IMP infusion until 8 weeks post IMP infusion. Prescheduled prophylactic DLI ≤3x105 T cells/kg BW in case of T-cell depleted HSCT is not considered an exclusion criterion.
• Patient with organ dysfunction or failure as determined by Karnofsky (patients \>16 years) or Lansky (patients ≤16 years) score ≤30%
• Concomitant enrolment in another clinical trial interfering with the endpoints of this study
• Any medical condition which could compromise participation in the study according to the investigator's assessment
• Progression of underlying disease (disease that has led to the indication of HSCT, e.g. leukaemia) that will limit the life expectance below the duration of the study
• Second line or experimental antiviral treatment other than Ganciclovir/Valganciclovir, Foscarnet, Cidofovir and Rituximab until 8 weeks after IMP Infusion or prophylactic Treatment other than Aciclovir or Letermovir throughout the study except approved by sponsor
• Known HIV infection. In case patients do not have a negative HIV test performed within 6 months before enrolment in the study, HIV negativity has to be confirmed by a negative laboratory test.
• Female patient who is pregnant or breast-feeding. Female patient of child-bearing potential (i.e. post menarche and not surgically sterilized) or male patient of reproductive potential not willing to use an effective method of birth control from Screening until the last follow-up visit (FU6, Visit 8).
• Note: Women of childbearing potential must have a negative serum pregnancy test at study entry ≤7 days before IMP administration on Day 0. Acceptable birth control methods are hormonal oral contraceptive ('pill'), contraceptive injection or patch, intrauterine pessar or the combination of two barrier methods. The combination of female and male condomes is NOT acceptable. If the male partner is sterilized, no further contraceptive is required. Women of post-menopausal status (no menses for 12 months without an alternative medical cause) are also not required to use contraceptives during the study.
• Known hypersensitivity to iron dextran
• Patients unwilling or unable to comply with the protocol or unable to give informed consent.
