The event was defined as an increase in size of prior sites of disease or evidence of new sites of disease, documented or not by biopsy. Disease relapse was diagnosed when there was morphological or clinical evidence of the following: reappearance of leukemia blast cells in the peripheral blood, or >5% blasts in the bone marrow (BM), not attributable to another cause (eg, BM regeneration), or the appearance of previous or new dysplastic changes (MDS specific) within the BM, with or without falling donor chimerism, or the development of extramedullary leukemia or leukemic cells in the cerebral spinal fluid, or institution of therapy to treat relapsed disease, including donor lymphocyte infusion.
Cumulative Incidence Percentage of Systemic Steroids for the Treatment of aGvHD +180 Days Post-HSCT
For each treatment arm, the cumulative incidence rate of systemic steroid use for the treatment of aGvHD by Day +180 post-HSCT will be estimated using the cumulative incidence competing risk estimator. The calculation of the cumulative incidence rates and the stratified Gray's test was carried out using the LIFETEST procedure in SAS version 9.4. If the participant experienced a competing risk event, then the initiation date was used to calculate the time-to-event variable.

Change from the baseline assessment to Days +100 and +180 post-HSCT in the index value was assessed. The index value total range is from a minimum value of -1 to a maximum value of +1. A higher EQ-5D-5L index value represents better quality of life (QoL), thus a positive change in the index value represents improved QoL.
