简要总结
This phase II trial studies the side effects of tagraxofusp in treating patients with blastic plasmacytoid dendritic cell neoplasm after stem cell transplant. Tagraxofusp is a type of immunotoxin that is made by linking a protein called IL-3 to a toxic substance. Tagraxofusp may help find cancer cells that express IL-3 and kill them without harming normal cells.
详细描述
PRIMARY OBJECTIVE:
I. To evaluate the safety of tagraxofusp-erzs (tagraxofusp) in patients with blastic plasmacytoid dendritic cell neoplasm (BPDCN) after autologous (auto) or allogeneic (allo) hematopoietic cell transplantation (HCT).
SECONDARY OBJECTIVES:
I. To estimate progression-free survival (PFS) in patients with BPDCN receiving maintenance therapy with tagraxofusp after auto-HCT or allo-HCT.
II. To estimate the overall survival (OS) in patients with BPDCN receiving maintenance therapy with tagraxofusp after auto-HCT or allo-HCT.

- •Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) =< 2.5 times ULN
- •Hemoglobin >= 8 g/dL with or without transfusion in the last 7 days
- •Absolute neutrophil count (ANC) >= 1000 without granulocyte colony stimulating factor (GCSF) or granulocyte-macrophage colony-stimulating factor (GMCSF) in the last 2 weeks prior to screening

- •Woman of child bearing potential (WOCBP) with a negative serum or urine pregnancy test within 14 days of tagraxofusp treatment
- •Patient or patient's legal representative, parent(s) or guardian able to sign informed consent

- •Pregnant or breast-feeding woman
- •Patient has uncontrolled intercurrent illness or medical/psychiatric condition that would limit compliance with study requirements or that would in the investigator's opinion place the patient at an unacceptably high risk for toxicities
- •Clinical significant cardiopulmonary disease including uncontrolled or New York Heart Association (NYHA) class 3 or 4 congestive heart failure, uncontrolled angina, uncontrolled hypertension, uncontrolled arrhythmia, myocardial infarction or stroke within 6 months of first protocol treatment or corrected QT (QTc) > 480 ms
