About this trial
Systemic mastocytosis with an associated hematologic neoplasm (SM-AHN) is a challenging disease to treat. Targeted KIT inhibitors have been approved for this indication based on their ability to control the mastocytosis portion of the disease, but patients frequently experience progression of the concomitant myeloid malignancy (i.e. the AHN). Using a combination approach to treat both aspects of the disease has the potential to provide enhanced disease control; however, overlapping toxicity is a concern. In this study, investigators aim to study the safety and tolerability of combined avapritinib and decitabine for the treatment of SM-AHN.
