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.

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.

Safety and Efficacy of ATIR101 as Adjunctive Treatment to Blood Stem Cell Transplantation From a Haploidentical Family Donor Compared to Post-transplant Cyclophosphamide in Patients With Blood Cancer

A Phase III, Multicenter, Randomized Controlled Study to Compare Safety and Efficacy of a Haploidentical HSCT and Adjunctive Treatment With ATIR101, a T-lymphocyte Enriched Leukocyte Preparation Depleted ex Vivo of Host Alloreactive T-cells, Versus a Haploidentical HSCT With Post-transplant Cyclophosphamide in Patients With a Hematologic Malignancy

Defined as the time until acute GVHD grade III/IV, chronic GVHD requiring systemic treatment, relapse, or death, whichever occurs first. Kaplan-Meier estimates (percentage of participants) of GRFS were calculated at 24 months post HSCT.

OS is defined as the time from HSCT until death from any cause. Kaplan-Meier estimates (percentage of participants) of OS were calculated at 24 months post HSCT.

Defined as the time from HSCT until relapse, disease progression, or death, whichever occurs first. Kaplan-Meier estimates (percentage of participants) of PFS were calculated at 24 months post HSCT.

Time from randomization to death due to disease relapse or disease progression

Defined as death due to causes other than disease relapse or progression, or other causes which are unrelated to the transplantation procedure (e.g. accident, suicide). Kaplan-Meier estimates (percentage of participants) of PFS were calculated at 24 months post HSCT.

Study was pre-maturely terminated. For the long term safety follow-up (LTFU), up to 24 months post-HSCT, only cumulative SAEs were recorded.

(63 patients had been enrolled (randomized); 32 to ATIR101 group and 31 to PTCy group (intention-to-treat \[ITT\] population). Only patients who received an HSCT and ATIR101 (n=16) or at least one dose of PTCy (n=27) were included in the modified ITT population (MITT). Eight ATIR101, and 22 PTCy treated patients entered 2 year LTFU).
