Study Endpoints
Primary Endpoints
Overall survival (all randomisations)
12 and 24 months

Defined as time from entering the relevant randomisation to the relevant question until death from any cause. Patients who are alive at the end of the trial or have been lost to follow up will be censored at their date last seen. For randomisations 2 and 3 this outcome will also be calculated as time from transplantation in order to run a sensitivity analysis.

Secondary Endpoints
Change in MRD status - R1 only
Assessed at baseline and pre-transplant
Disease-free survival
From date of randomisation through to study completion, an average of 6 years
Cumulative incidence of disease relapse
From date of randomisation through to study completion, an average of 6 years
