Termination was due to significant challenges associated with study enrollment in a genetic subset of fit participants in the front-line acute myeloid leukemia (AML) setting and other challenges associated with post-COVID impacts.
Early termination was due to significant unforeseen challenges associated with global enrollment of participants with genetically-defined, newly diagnosed, AML who are candidates for intensive induction therapy and other challenges associated with post-COVID impacts.

Problems unique to COVID-19, incomplete data due to a high rate of dropout to minimize non-essential appointments and difficult subject recruitment
COVID-19 pandemic occurred during study meaning high rates of patients lost to follow-up, as non-emergent visits were canceled or postponed. This led to early termination which means we had a small number of subjects to analyze, especially those who completed all 12 months of follow-up. By the time pandemic restrictions eased, several other studies had published results on similar trials, making further enrollment unnecessary and further supporting early termination of the study.
