"Since ELZONRIS became commercially available in January, we have been very pleased with the progress we have made executing our launch plan," stated Robert Francomano, SVP and Global Head of Commercial. "Our entire organization is working hard to ensure patients with BPDCN have access to ELZONRIS. Although still early, we believe the launch is progressing extremely well and remain poised for a very successful 2019 and beyond."
Ivan Bergstein, M.D., CEO of Stemline Therapeutics, commented "We have built a solid foundation for growth, driven by our launch of ELZONRIS for patients with BPDCN. We are executing our commercial plan, including pursuing ongoing efforts to unlock additional value from ELZONRIS in other indications as well as from our entire pipeline, all with the goal of improving the lives of patients with cancer around the world."
First Quarter 2019 Financial Results Review
Net revenue for ELZONRIS was $5.05 million for the quarter ended March 31, 2019. Stemline began commercial sales of ELZONRIS within the United States in January 2019.
Stemline ended the first quarter with $124.4 million in cash, cash equivalents and investments. For the first quarter, Stemline had a net loss of $27.4 million. Cash expenditures for the first quarter of 2019 was $21.9 million.
Research and development expenses were $17.0 million for the first quarter of 2019, which reflects an increase of $4.3 million compared with $12.7 million for the first quarter of 2018. The higher cost was primarily driven by expense recorded related to repayment of research funding as a result of the first commercial sale of ELZONRIS.
Selling, general and administrative expenses were $16.0 million for the first quarter of 2019, which reflects an increase of $10.1 million compared with $5.9 million for the first quarter of 2018. The increase in costs were primarily attributable to launch expenses in support of the commercialization of ELZONRIS.
Recent Corporate Developments and Program Highlights
ELZONRIS (tagraxofusp) — Blastic plasmacytoid dendritic cell neoplasm (BPDCN)
· ELZONRIS was approved by the FDA on December 21, 2018 and commercially available for patients with BPDCN in the U.S. in January 2019.
· The New England Journal of Medicine published the pivotal trial results in its April 25th edition.

ELZONRIS — Market Expansion Efforts
· We are conducting clinical trials to evaluate ELZONRIS in additional indications, including chronic myelomonocytic leukemia (CMML), myelofibrosis (MF), and acute myeloid leukemia (AML).
· Based on clinical results observed in patients with CMML and MF, we are evaluating next steps, including potential registrational pathways. For CMML, we intend to provide our registration-directed plans mid-year.
·We are also evaluating additional expansion opportunities, including maintenance therapy after stem cell transplant in patients with BPDCN.
· In parallel, we plan to expand our clinical efforts later this year and next into subsets of AML patients, including those enriched for CD123+ expression.
· We expect to provide periodic updates on these programs throughout this year and next at scientific conferences.
ASCO Conference
· ELZONRIS clinical trial data in CMML and MF have been selected for two poster presentations at the 2019 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) conference in June.
Other pipeline candidates

About BPDCN
BPDCN is an aggressive hematologic malignancy with historically poor outcomes and an area of unmet medical need. BPDCN typically presents in the bone marrow and/or skin and may also involve lymph nodes and viscera. The BPDCN cell of origin is the plasmacytoid dendritic cell (pDC) precursor. The diagnosis of BPDCN is based on the immunophenotypic diagnostic triad of CD123, CD4, and CD56, as well as other markers. For more information, please visit the BPDCN disease awareness website at www.bpdcninfo.com.
About CD123
CD123 is a cell surface target expressed on a wide range of myeloid tumors including blastic plasmacytoid dendritic cell neoplasm (BPDCN), certain myeloproliferative neoplasms (MPNs) including chronic myelomonocytic leukemia (CMML) and myelofibrosis (MF), acute myeloid leukemia (AML) (and potentially enriched in certain AML subsets), myelodysplastic syndrome (MDS), and chronic myeloid leukemia (CML). CD123 has also been reported on certain lymphoid malignancies including multiple
myeloma (MM), acute lymphoid leukemia (ALL), hairy cell leukemia (HCL), Hodgkin’s lymphoma (HL), and certain Non-Hodgkin’s lymphomas (NHL). In addition, CD123 has been detected on some solid tumors as well as autoimmune disorders including cutaneous lupus and scleroderma.
