Tagraxofusp in Patients With Blastic Plasmacytoid Dendritic Cell Neoplasm or Acute Myeloid Leukemia
brief summary
This is a 4-stage, non-randomized, open-label, dose escalation and expansion, multicenter study. A cycle of therapy is 21 days. Stage 1 was a dose-escalation stage. During Stages 2-4, patients are treated at the MTD or maximum tested dose at which multiple DLTs are not observed during Stage 1.
detailed description
Study 0114 is a multi-stage, non-randomized, open-label, multicenter study of Tagraxofusp in First line and Relapsed/Refractory (R/R) Blastic Plasmacytoid Dendritic Cell Neoplasm (BPDCN) and Acute Myeloid Leukemia (AML) patients divided into 4 stages.
Each study stage has its own unique objectives and patient population, with Stage 1 representing the dose escalation phase and Stage 3 the pivotal phase.
In Stages 1 and 2, both patients with BPDCN (first-line and R/R) and AML were enrolled; Stage 3 enrolled previously untreated (first-line) BPDCN patients only. A separate stage, Stage 4, enrolled First-line and R/R BPDCN patients to further characterize safety and efficacy of Tagraxofusp.
The primary study objectives are reported below by stage:
Stage 1: to determine the Maximum Tolerated Dose (MTD) (or Maximum Tested Dose, MTeD where multiple DLTs were not observed) of Tagraxofusp administered at the following dose levels 7, 9, 12, 16 µg/kg/day
Stage 2: cohort expansion to determine the efficacy and safety of Tagraxofusp at the MTD selected in Stage 1
Stage 3 (pivotal): to determine the efficacy and safety of Tagraxofusp in patients with First-line BPDCN
Stage 4: to further characterize the efficacy and safety of Tagraxofusp in patients with both First-line and R/R BPDCN
