The primary endpoint, the cumulative incidence of non-relapse mortality (NRM) within 180 days after transplantation, was 8.7% (95% CI, 3.8-16.2%), which was below the prespecified threshold of 30%.

Between June 2017 and March 2019, a total of 82 patients were enrolled from 40 participating centers. After exclusion of two ineligible patients, 80 patients were included in the analysis.
Serious adverse events requiring expedited reporting included seven deaths within 100 days after transplantation, one death occurring after day 100 that could not be ruled out as related to the protocol treatment, one case of grade 4 elevated serum amylase, two cases of grade 4 renal impairment, and one case of graft failure.
The incidences of major grade 3 or higher adverse events within 30 days after transplantation were oral mucositis (14%), nausea/vomiting (26%), diarrhea (25%), infections (29%), and febrile neutropenia (48%).
