GlycoMimetics, Inc. (NASDAQ: GLYC) announced today dosing of the first patient in the company’s Phase 3 clinical trial of uproleselan (GMI-1271) in relapsed/refractory AML. The trial’s protocol provides for administration of the investigational drug in combination with MEC (mitoxantrone, etoposide and ara-C) or in combination with FAI (fludarabine, ara-C and idarubicin), both of which are standard of care for this indication in the United States. In 2017, the U.S. Food and Drug Administration (FDA) granted Breakthrough Therapy Designation to GlycoMimetics for uproleselan in this patient population. The company anticipates the initiation of two complementary Phase 2/3 trials from two leading clinical consortia in early 2019.
