Stemline Therapeutics Reports Third Quarter 2016 Financial Results And Highlights Recent Regulatory And Clinical Progress

NEW YORK, Nov. 08, 2016 (GLOBE NEWSWIRE) -- Stemline Therapeutics, Inc. (Nasdaq:STML) today reported financial results for the quarter ended September 30, 2016.

Ivan Bergstein, M.D., Stemline's Chief Executive Officer, commented, "A key highlight of the quarter was the FDA granting SL-401 Breakthrough Therapy designation for the treatment of blastic plasmacytoid dendritic cell neoplasm (BPDCN), a deadly malignancy of the immune system of unmet medical need. We also continue to make significant progress across our entire pipeline, resulting in seven presentations, including an oral presentation of updated Phase 2 trial results of SL-401 in BPDCN, at the upcoming American Society of Hematology (ASH) annual meeting."

Dr. Bergstein concluded, "We look forward to gaining further clarity around our BPDCN registration pathway and timelines in the near-term, and have begun to build-out our pre-commercial infrastructure in preparation for success. Importantly, our strong cash position provides us with the resources to reach important clinical, regulatory and commercial milestones across our many programs."

Third Quarter 2016 Financial Results ReviewStemline ended the third quarter of 2016 with $74.3 million in cash, cash equivalents and investments, as compared to $81.2 million as of June 30, 2016, which reflects a cash burn of $6.9 million for the quarter.

For the third quarter of 2016, Stemline had a net loss of $9.9 million, or $0.56 per share, compared with a net loss of $9.2 million, or $0.53 per share, for the same period in 2015.

Research and development expenses were $7.2 million for the third quarter of 2016, which reflects a decrease of $0.1 million, or 2%, compared with $7.3 million for the third quarter of 2015.

General and administrative expenses were $3.2 million for the third quarter of 2016, which reflects an increase of $1.0 million, or 43%, compared with $2.2 million for the third quarter of 2015. The increase in expense was primarily attributable to higher non-cash stock based compensation and payroll costs relating to employees.

About Stemline Therapeutics Stemline Therapeutics, Inc. is a clinical stage biopharmaceutical company developing novel oncology therapeutics. Stemline is developing three clinical stage product candidates, SL-401, SL-801, and SL-701. SL-401 is a targeted therapy directed to the interleukin-3 receptor (CD123) present on a wide range of malignancies. SL-401 is being advanced through a potentially pivotal Phase 2 trial in patients with blastic plasmacytoid dendritic cell neoplasm (BPDCN), an indication for which SL-401 has been granted Breakthrough Therapy Designation (BTD) by the FDA. SL-401 has demonstrated high overall response rates (ORR), with multiple complete responses (CRs), in both first-line and relapsed refractory patients, and response-driven outcomes including treatment duration and frequency of bridge to transplant have been trending favorably. SL-401 is also being advanced through Phase 1/2 trials of patients with additional malignancies including acute myeloid leukemia (AML) in remission with minimal residual disease (MRD), high risk myeloproliferative neoplasms (MPN), and relapsed/refractory multiple myeloma (in combination with pomalidomide). SL-801 is a novel oral small molecule reversible inhibitor of XPO1 that has demonstrated broad in vivo and in vitro preclinical activity in a wide array of solid and hematologic malignancies. A Phase 1 trial with SL-801 is open and enrolling patients with advanced solid tumors, and a Phase 1 trial in hematologic malignancies is planned. SL-701 is an immunotherapy designed to activate the immune system to attack tumors. A Phase 2 trial with SL-701 in adult patients with second-line glioblastoma multiforme (GBM) is ongoing.
