Ivan Bergstein, M.D., CEO of Stemline Therapeutics, commented, “We are honored that ASH has selected the BPDCN pivotal results for oral presentation. This selection underscores the heightening awareness of the disease – BPDCN, the target – CD123, and the clinical impact of the drug candidate – ELZONRIS. In addition, our regulatory team continues to work diligently in an effort to make ELZONRIS available to patients as quickly as possible, and our commercial team continues to execute on our broad-based pre-launch initiatives. This includes the build-out of our sales, marketing and reimbursement teams as well as continuing to advance our disease awareness campaign. In parallel, we are excited to present updated clinical data from our ongoing clinical trials in patients with chronic myelomonocytic leukemia (CMML) and myelofibrosis (MF). Based on these data, we are enthusiastic about our plans to implement pivotal trials, or cohorts, in these devastating malignancies.”
