Highest Dose of Uproleselan in Combination With Fludarabine and Cytarabine for Patients With Acute Myeloid Leukemia, Myelodysplastic Syndrome, or Mixed Phenotype Acute Leukemia Relapsed or Refractory That Expresses E-selectin Ligand on the Cell Membrane (NCT05146739)

A Phase 1 and Pharmacokinetic Study of Uproleselan (GMI-1271, NSC #801708) in Combination With Fludarabine and Cytarabine for Patients With Acute Myeloid Leukemia, Myelodysplastic Syndrome or Mixed Phenotype Acute Leukemia That Expresses E-selectin Ligand on the Cell Membrane and is in Second or Greater Relapse or That is Refractory to Relapse Therapy

๐Ÿ”ต Active, Not Recruiting Phase1 ๐Ÿ’Š Investigational Drug / Biologic Sponsor: National Cancer Institute (NCI)

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

This phase I trial tests the safety, side effects, and determination of the best dose of uproleselan in combination with fludarabine and cytarabine in treating patients with acute myeloid leukemia, myelodysplastic syndrome or mixed phenotype acute leukemia that has come back (relapsed) or does not respond to treatment (refractory) and that expresses E-selectin ligand on the cell membrane. Uproleselan binds to E-selectin expressed on endothelial cells of the bone marrow and prevents their interaction with selectin-E ligand-expressing cancer cells. This may prevent leukemia cells from being sequestered in the bone marrow niche and escaping the effect of chemotherapy. Chemotherapy drugs, such as fludarabine and cytarabine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving uproleselan in combination with fludarabine and cytarabine may expose more cancer cells to the effect of chemotherapy.
