Tagraxofusp-erzs, an IL-3 Diphtheria Fusion Protein, in Combination With Gemtuzumab Ozogamicin in Patients With Relapsed/Refractory AML

NCT05716009

Non-randomizedSequentialOpen-labelTreatment

Summary

This is an open-label Phase Ia/Ib clinical study of tagraxofusp-erzs, a novel cytokine-drug conjugate that links interleukin-3 with a truncated diphtheria toxin, in combination with gemtuzumab ozogamicin for patients with relapsed/refractory AML. The primary objective of the study is to determine the recommended phase 2 dose (RP2D) of tagraxofusp-erzs in combination with gemtuzumab ozogamicin in this patient population. Then, once RP2D is determined, to determine the safety and tolerability of combination gemtuzumab and tagraxofusp-erzs when administered at the RP2D.
