Feasibility and Efficacy of Modified Donor Lymphocytes Infusion (CD45RA Negative Selected) After Haploidentical Transplantation With Post-transplantation Cyclophosphamide in Patients With Hematological Malignancies (ONC-2016-002).
Interventional non-randomized trial. The duration of study will be 47 months.
After haploidentical transplantation, patients without complications, mainly a GVHD ≥ grade 2, will receive mDLI. mDLI consists of donor lymphocytes infusion, harvested by apheresis the day before the day planned for infusion (or up to -7 days) as outpatient basis in the Day Hospital using a cell separator.
The mDLIs preparation will be performed using a CliniMACS® (Miltenyi). A CD45RA-depletion Product LineTM from Miltenyi, including disposable reagents and devices, will be used.
The planned number of mDLI is 3.
- Day +50 (+/- 7 days) from allogenic transplant, 1st mDLI 5x105CD3+/kg of recipient.
- 4-6 weeks after 1st DLI, 2nd mDLI 1x106CD3+/kg of recipient.
- 4-6 weeks after 2nd DLI, 3rd mDLI 5x106CD3+/kg of recipient. Day +50 was chosen as the starting time-point because at that time over two thirds of all acute GvHD episodes have already occurred in the absence of DLI (internal data, median +49 after bone marrow, +27 after peripheral stem cells); acute GvHD will thus be less likely a confounding factor. The choice of a maximum number of 3 mDLIs is based on the relatively narrow time interval where outcome improvement is expected, that is mainly in the first 6 months after haplo-HSCT. The planned doses are those mainly used in conventional DLIs during haplo-HSCT setting.
Stopping infusion rules:
If GvHD ≥ Grade 2 or relapse occurs, mDLIs will not be administered at any time and patient will be permanently discontinued from treatment.
If any severe adverse event (SAE) occurs after the first mDLI, the administration of mDLI will be interrupted for a maximum of 6 weeks until event resolution. If the SAE does not resolve after 6 weeks from last mDLI infusion, patient will be permanently discontinued. At any time, the experimental treatment may be stopped according to clinical judgement or patient's willing.
