Receiving glucocorticoid (GC) treatment (prednisone/prednisolone) for >=4 consecutive weeks for >=10 days prior to randomization.
Disqualifiers

Trial outcomes
Primary outcomes
ORR (Objective response rate) at Week 26
ORR is defined as the proportion of participants who have achieved complete response (CR) or partial response (PR) during the 26-week Primary Treatment Period.
Secondary outcomes
Phase 2: Percentage of participants with partial response (PR) or complete response (CR) at Week 26
Percentage of participants with PR or CR at Week 26 to support identification of the Recommended Phase 3 dose (RP3D)
Phase 2: Number of participants with adverse events and clinically significant changes in laboratory parameters, and vital signs to support identification of the RP3D
Phase 2: Plasma concentrations of momelotinib and metabolite of momelotinib 21 (M21) to support identification of the RP3D
Number of flare-free days
Flare-free days are calendar days without clinical evidence of VEXAS flare and without treatment escalation. Total number of flare-free days is defined as the cumulative number of consecutive and non-consecutive flare-free days.
