  • 5. Patients must have BSC for ISM symptom management stabilized for at least 14 days prior to starting screening procedures.
  • 6. For patients receiving corticosteroids, the dose must be = 20 mg/d prednisone or equivalent, and the dose must be stable for = 14 days.
  • 7. Patients must have mMCAS, confirmed by Central Pathology Review of BM biopsy. An archival biopsy may be used if completed within the past 12 months.
  • 8. Patients must have tryptase < 20 ng/mL.
  • 9. Patients must have KIT D816V in peripheral blood (PB) or BM and/or CD25+ Mast cells in BM.
