Fig. 4: Overall survival probability.

There were three deaths in the trial. One patient died due to a cardiac arrest while in MMR. The cause of death was unknown for the second patient. A third patient died after falling from stairs. The latter two patients had regained deep molecular response at the level MR4 after re-commencing TKI therapy for MMR-loss. At 48 months, 53 patients were still under observation.
