The readout consisted of mean durations of feedback (DOR) of 15.7 months in the evorpacept cohort and 7.6 months in the command arm. The progression-free survival (PFS) and overall survival records are premature. Lettmann stated DOR "ought to associate with PFS." ALX designed the research as a phase 2/3 study.
