Clinical Trial Summary

The primary objective of this study is to compare safety and efficacy of a haploidentical T-cell depleted HSCT and adjunctive treatment with ATIR101 versus a haploidentical T cell replete HSCT with post-transplant administration of high dose cyclophosphamide (PTCy) in patients with a hematologic malignancy. An additional objective of the study is to compare the effect of the two treatments on quality of life.

Description:

Study CR-AIR-009 is a Phase III randomized controlled multicenter open-label study comparing two parallel groups. After signing informed consent, a total of 250 patients will be randomized in a 1:1 fashion to receive either a T-cell depleted hematopoietic stem cell transplantation (HSCT; CD34 selection) from a related, haploidentical donor, followed by ATIR101 infusion, or a T-cell replete HSCT, followed by a high dose of post-transplant cyclophosphamide (PTCy). Randomization will use minimization to balance treatment groups with respect to underlying disease (AML, ALL, or MDS), Disease Risk Index (DRI; intermediate risk, high risk, or very high risk) and center. A stochastic treatment allocation procedure will be used so that the treatment assignment is random for all patients entered in the study. Patients randomized in the ATIR101 group will receive a single ATIR101 dose of 2×10E6 viable T-cells/kg between 28 and 32 days after the HSCT. Patients randomized in the PTCy group will receive cyclophosphamide 50 mg/kg/day at 3 and 4/5 days after the HSCT. All patients will be followed up for at least 24 months post HSCT.

Intervention

Biological:
• ATIR101
ATIR101 is a T-lymphocyte enriched leukocyte preparation depleted ex vivo of host alloreactive T-cells using photodynamic treatment; single dose of 2×10E6 viable T-cells/kg body weight between 28 and 32 days after the HSCT (intravenous infusion)

Drug:
• Cyclophosphamide
High dose post-transplant cyclophosphamide 50 mg/kg/day at 3 and 4/5 days after the HSCT (powder for intravenous infusion)

Procedure:
• T-cell depleted HSCT from a related, haploidentical donor
T-cell depleted graft prepared from peripheral blood stem cells using the CD34+ cell selection method; infused after a total body irradiation (TBI) or non-TBI conditioning regimen
• T-cell replete HSCT from a related, haploidentical donor
T-cell replete (full, non-manipulated) graft prepared from either bone marrow or peripheral blood stem cells; infused after a total body irradiation (TBI) or non-TBI conditioning regimen
