Stemline Therapeutics Reports Fourth Quarter 2016 Financial Results

NEW YORK, March 16, 2017 (GLOBE NEWSWIRE) -- Stemline Therapeutics, Inc. (Nasdaq:STML), a clinical-stage biopharmaceutical company developing novel therapeutics for oncology indications of unmet medical need, announced today financial results for the quarter ended December 31, 2016. The company also reviewed clinical and regulatory events from the past quarter, and outlined key upcoming milestones:

SL-401 In Blastic Plasmacytoid Dendritic Cell Neoplasm (BPDCN)

  • SL-401 Phase 2 clinical trial results in patients with blastic plasmacytoid dendritic cell neoplasm (BPDCN) delivered as an oral presentation at the 2016 American Society of Hematology (ASH) annual meeting.
  • After receipt of breakthrough therapy designation in 3Q16, Stemline had a successful meeting with the U.S. Food and Drug Administration (FDA) resulting in a defined registration pathway for possible full approval in first-line BPDCN.
    - Stemline is currently enrolling patients in a new cohort (Stage 3) that is expected to enroll approximately 8-12 first-line BPDCN patients.
    - Completion of enrollment of the Stage 3 cohort expected this quarter. We plan to provide clinical results from this cohort in the second half of this year.

Additional Clinical Trials

  • SL-401 is being clinically evaluated in several additional indications including certain high-risk myeloproliferative neoplasms (MPN), acute myeloid leukemia (AML) in complete remission with minimal residual disease, and with relapsed/refractory multiple myeloma. SL-801 is being evaluated in a Phase 1 dose escalation trial of advanced solid tumor patients. SL-701 has completed dosing in a Phase 2 trial in second-line glioblastoma. Updates from these studies are expected this year.

Fourth Quarter 2016 Financial Results Review
Stemline ended the fourth quarter of 2016 with $67.6 million in cash, cash equivalents and investments, as compared to $74.3 million as of September 30, 2016, which reflects a cash burn of $6.7 million for the quarter. Subsequent to year end 2016, Stemline completed a follow-on public offering during January 2017 raising $48.2 million in net cash proceeds bringing total cash, cash equivalents and investments to approximately $110.0 million as of March 16, 2017.

For the fourth quarter of 2016, Stemline had a net loss of $10.0 million, or $0.56 per share, compared with a net loss of $10.2 million, or $0.58 per share, for the same period in 2015.

Research and development expenses were $7.3 million for the fourth quarter of 2016, which reflects a decrease of $0.6 million, or 8%, compared with $7.9 million for the fourth quarter of 2015. The lower costs reflect a one-time payroll-related expense in 2015 partially offset by higher non-cash stock based compensation expense in 2016.

General and administrative expenses were $3.1 million for the fourth quarter of 2016, which reflects an increase of $0.5 million, or 19%, compared with $2.6 million for the fourth quarter of 2015. The increase in costs was primarily attributable to higher non-cash stock based compensation expense and the commencement of building infrastructure to support a potential commercial launch of SL-401 for BPDCN.
