Systemic corticosteroids at any dose, may be used during the screening period for symptom control, but must be tapered down, if necessary, to 20mg/day prior to dosing with AZD4573. Doses of systemic corticosteroid >20mg/day may be used during the study if clinically indicated (e.g., for treatment of an AE/SAE), but again, the dose must be tapered back down to no greater than 20mg/day upon resolution of the event, to avoid chronic use.
In addition, the following is considered a criterion for exclusion from the optional genetic research:
• Previous allogeneic bone marrow transplant
