Minnelide in Adult Patients With Relapsed or Refractory Acute Myeloid Leukemia

Summary

Minnelide, a water-soluble disodium salt variant of triptolide, is a diterpenoid heat shock protein 70 (HSP70) inhibitor. Studies using AML cell lines, primary patient samples, and mouse transplant models demonstrate that Minnelide has potent cell killing effects. Minnelide has already been developed for human use and given to patients in a phase I trial for gastrointestinal (GI) cancers. Given the clinical safety profile and preliminary activity described in human GI cancers, the low-nanomolar anti-leukemic potency of triptolide in vitro, and that minnelide doses predicted to be significantly below the maximum tolerated dose (MTD) in human GI cancers decreased leukemia burden in animal models, the investigators propose a phase I trial in acute myeloid leukemia (AML).
