Details on the presentations are as follows:Ivan Bergstein, M.D., Stemline’s Chief Executive Officer, commented, “We are honored to be showcasing, via oral presentation, the results of our SL-401 pivotal trial in BPDCN to a European audience via the EHA Congress. We believe this selection underscores SL-401’s robust clinical data and increased global awareness of BPDCN, a devastating malignancy of high unmet medical need. In the U.S., we remain on track to complete our rolling Biologics License Application (BLA) submission this quarter. In Europe, we anticipate feedback later this year from the European Medicines Agency (EMA) regarding the timing of a potential regulatory filing in the European Union. In addition, we and our investigators continue to report encouraging signs of clinical activity and safety in indications beyond BPDCN, including chronic myelomonocytic leukemia (CMML) and myelofibrosis (MF), and we look forward to presenting updated data from these indications at the conference.”Following each presentation at the conference, the data presented will be available on Stemline’s website ( under the Scientific Presentations tab.About BPDCN
