简要总结
The goal of this clinical trial is to study the efficacy of the tagraxofusp + venetoclax combination in treatment-naive blastic plasmacytoid dendritic cell neoplasm adult patients.
The main question is to verify the response in patients after 3 cycles of tagraxofusp+venetolax and to demonstrate if the combination of tagraxofusp + venetoclax increases the rate of complete remission, assessed after 3 months of treatment.
Patients will receive a ramp-up phase of venetoclax during 3 days and at least 3 cycles of venetoclax. After, the investigators will evaluate the response, and depending on the response observed, patients may receive additional cycles of treatment for a maximum of 24 cycles, or receive an allograft or discontinue the treatment in the case of therapeutic failure.

研究组 & 干预措施
Single interventional arm
For each 28 days-cycle of treatment :
- venetoclax 400mg/day orally after a ramp-up period of 3-days
- tagraxofusp starting at the end of the venetoclax ramp-up period i.e. at day 4 for twelve 28-days cycles, 12 μg/kg body weight administered as an intravenous infusion over 15 minutes, once daily, on days 1-3 of each cycle
干预措施: Venetoclax (Drug)
