High-dose Chemotherapy With Transplantation of Gene-modified Haematopoietic Stem Cells for HIV-positive Patients With Malignant Diseases Indicating an HSCT

September 4, 2022 updated by: Universitätsklinikum Hamburg-Eppendorf
Patient stem cells will be mobilized with induction chemotherapy (R)-ICE and G-CSF. If sufficient cells can be mobilized, patients will be treated with high-dose chemotherapy and a transplant of autologous CD34+ cells transduced with an antiviral vector (M87o). If autologous CD34+ yield is insufficient, allogeneic gene-modified cells will be given, if a compatible donor is available. To minimize risk of transplant failure, a second unmodified CD34+ cell transplant will be given one week after the first transplant.

  • Participation in another study with an investigational product within less than one month prior to this study
  • Simultaneous participation in a study with an investigational drug
  • Presence of any disease likely to require procedures altering the schedule of the protocol
  • Patients with a history of seizures, central nervous system disorders or psychiatric disability thought to be clinically significant in the opinion of the investigator
