Stemline Therapeutics Reports Second Quarter 2019 Financial Results

Published

  • Net revenue for ELZONRIS® was $13.0 million for the second quarter
  • Conference call and live webcast scheduled for today at 8:00 AM ET

NEW YORK, Aug. 02, 2019 (GLOBE NEWSWIRE) -- Stemline Therapeutics, Inc. (Nasdaq: STML), a commercial-stage biopharmaceutical company focused on the development and commercialization of novel oncology therapeutics, today reported financial results and business highlights for the second quarter ended June 30, 2019.

“We are very excited with the progress we continue to make on the ELZONRIS U.S. launch. Our commercial team continues to generate strong momentum, as evidenced by robust sales, steady increases in new patient starts and a broadening prescriber base,” stated Robert Francomano, SVP and Global Head of Commercial. “Our entire organization is focused on ensuring patients with BPDCN gain access to ELZONRIS, and given the trends we are seeing, we remain poised for a successful 2019 and beyond.”

Ivan Bergstein, M.D., CEO of Stemline Therapeutics, commented: “We are very pleased with the continued strong commercial performance and the rapid, broad-based adoption of ELZONRIS in the marketplace. 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 building a leading biopharmaceutical company and improving the lives of patients with cancer around the world.”

Second Quarter 2019 Financial Results ReviewNet revenue for ELZONRIS was $13.0 million for the quarter ended June 30, 2019. Stemline began commercial sales of ELZONRIS within the United States in January 2019.

Stemline ended the second quarter with $103.9 million in cash, cash equivalents and investments. For the second quarter, Stemline had a net loss of $16.8 million. The net cash expenditures for the second quarter of 2019 was $20.5 million.

Research and development expenses were $10.9 million for the second quarter of 2019, which reflects a decrease of $0.3 million compared with $11.2 million for the second quarter of 2018. The lower costs in the current period were primarily due to expenses in the prior year related to our biologics license application (BLA) filing for ELZONRIS with the FDA. 

Selling, general and administrative expenses were $19.0 million for the second quarter of 2019, which reflects an increase of $10.4 million compared with $8.6 million for the second quarter of 2018. The increase in costs were primarily attributable to pre-launch and launch expenses in support of the commercialization of ELZONRIS in the U.S. and potential launch in the European Union.

Recent Business Highlights

Commercial

  • Net revenue of ELZONRIS were $13.0 million during the second quarter, representing a 157% increase over last quarter.
  • The Centers for Medicare and Medicaid Services (CMS) recently assigned a J-Code for ELZONRIS, which happened one quarter earlier than we expected. The J-Code is a permanent code assigned to ELZONRIS by CMS and used by Medicare, Medicaid, and commercial payers for billing and claims processing. With a permanent J-code, ELZONRIS billing becomes more efficient, particularly in the outpatient setting.
  • On the private payer side, ELZONRIS now has favorable coverage for over 100 million lives, with coverage policy decisions to the label for key commercial payers.
  • We continue to execute on our disease awareness efforts which are designed to raise the profile of BPDCN and underscore the importance of CD123 testing.

Market Expansion Efforts

  • Blastic plasmacytoid dendritic cell neoplasm (BPDCN)• Stemline announced today that the Phase 2 investigator-sponsored clinical trial of ELZONRIS in patients with BPDCN as maintenance therapy post-stem cell transplant (SCT) has been granted regulatory authorization to proceed. The trial will evaluate the safety and feasibility of ELZONRIS in the maintenance setting for patients with BPDCN after SCT. We expect to provide further program updates later this year.
  • Chronic myelomonocytic leukemia (CMML)• ELZONRIS clinical data from its ongoing Phase 2 clinical trial in patients with CMML were presented at the 2019 American Society of Clinical Oncology (ASCO) annual meeting in Chicago, Illinois and at the 24th Congress of the European Hematology Association (EHA) in Amsterdam, Netherlands.• We plan to open an additional single-arm cohort, Stage 3, of patients with previously-treated CMML to the currently enrolling trial later this year. In the first part of Stage 3 (Stage 3a), enrichment strategies and certain efficacy endpoints, including spleen size reduction and bone marrow complete response with partial hematologic recovery, will be assessed for potential inclusion in the confirmatory cohort (Stage 3b), that will aim to provide the primary evidence of efficacy to support potential registration.
  • Myelofibrosis (MF)• ELZONRIS clinical data from its ongoing Phase 2 clinical trial in patients with MF were presented at the 2019 American Society of Clinical Oncology (ASCO) annual meeting in Chicago, Illinois and at the 24th Congress of the European Hematology Association (EHA) in Amsterdam, Netherlands.• The trial continues to enroll and we expect to provide further program updates later this year.
  • Systemic sclerosis• ELZONRIS preclinical results in systemic sclerosis, an autoimmune disorder in which CD123+ plasmacytoid dendritic cells (pDCs) play a role in disease pathogenesis, were presented at the Annual European Congress of Rheumatology (EULAR) in Madrid, Spain.
  • Acute myeloid leukemia (AML) and others• ELZONRIS in combination with other agents is currently being evaluated in an investigator-sponsored Phase 1/2 trial of patients with AML and high-risk myelodysplastic syndrome (MDS). Additional investigator-sponsored trials of ELZONRIS in combination with other agents in patients with subsets of AML that are enriched for CD123+ and/or BPDCN-like features are targeted to open in the 4Q19/1H20 timeframe. Other indications are also under consideration.

Ex-U.S.

  • Stemline continues to build out a European commercial infrastructure in advance of potential approval by the European Medicines Agency (EMA). The ELZONRIS marketing authorization application (MAA) is under review on a standard timeline. In June 2019, we received the day 120 list of questions relating to chemistry, manufacturing and controls (CMC), quality, non-clinical, and all stages of the clinical trial, including stage 4 largely involving lyophilized drug product. We have requested, and received, a clock stop extension. A scientific advisory group meeting is being planned. Based on this timeline, we expect an opinion from the Committee for Medicinal Products for Human Use (CHMP) in 1H20. In anticipation of potential regulatory success, we have started to hire personnel to meet the needs of a possible mid-2020 European commercial launch.
  • Stemline has instituted a global Early Access Program (EAP) whereby physicians may seek access to ELZONRIS outside of a clinical trial and/or before it is commercially available.
  • ELZONRIS clinical trial data in patients with BPDCN continue to be featured at prominent international hematological conferences with recent presentations in Europe and an upcoming oral presentation at a major medical meeting in Asia.

Additional Pipeline Candidates

  • Stemline continues to advance its clinical stage assets, including SL-801 (felezonexor), a reversible inhibitor of XPO1. Updated Phase 1 data were selected for presentation at the upcoming European Society for Medical Oncology (ESMO) meeting. Stemline is also developing its preclinical assets SL-1001 (RET kinase inhibitor) and SL-901 (kinase inhibitor), both of which are in IND-enabling studies and are expected to enter the clinic next year.

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 CD123CD123 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).
