Stemline Therapeutics Reports Third Quarter 2015 Financial Results

NEW YORK, Nov. 6, 2015 (GLOBE NEWSWIRE) -- Stemline Therapeutics, Inc. (Nasdaq:STML) today reported financial results for the quarter ended September 30, 2015.

Ivan Bergstein, M.D., Stemline's Chief Executive Officer, commented, "During the third quarter, we made significant progress on many fronts as we continue to advance our clinical programs forward. We are actively enrolling patients, and opening additional sites, in the expansion stage of our ongoing SL-401 pivotal trial in blastic plasmacytoid dendritic cell neoplasm, BPDCN. We look forward to sharing clinical updates from both the lead-in and initial expansion stages of this trial at the upcoming American Society of Hematology (ASH) meeting this December, and on into next year."

Dr. Bergstein continued, "We remain focused on the BPDCN indication while continuing to pursue expansion opportunities for SL-401 in additional malignancies. We have single agent trials currently open in several indications and we anticipate combination studies coming on-line as well. We are also continuing to develop our other pipeline candidates, SL-701 and SL-801, and look forward to treating our first patient with SL-801, our novel XPO1 inhibitor, early next year. With a strong cash position and multiple ongoing programs advancing across a range of indications of unmet medical need, we remain focused on achieving our objective of building a leading commercial stage biopharmaceutical company."

Third Quarter 2015 Financial Results Review

Stemline ended the third quarter of 2015 with $104.0 million in cash, cash equivalents and investments, as compared to $58.6 million as of December 31, 2014. In the first quarter of 2015, the Company completed an equity offering raising $68.6 million in gross cash proceeds on the sale of 4.4 million common shares.

For the third quarter of 2015, Stemline had a net loss of $9.2 million, or $0.53 per share, compared with a net loss of $6.9 million, or $0.53 per share, for the same period in 2014.

Research and development expenses were $7.3 million for the third quarter of 2015, which reflects an increase of $2.3 million compared with $5.0 million for the third quarter of 2014. The higher expenses during the third quarter were primarily attributable to the ramp up of SL-401 and SL-701 clinical activities. Also, we incurred costs relating to SL-801 IND-enabling studies.

General and administrative expenses were $2.2 million for the third quarter of 2015, which reflects an increase of $0.2 million compared with $2.0 million for the third quarter of 2014. The higher costs were primarily attributable to an increase in non-cash stock based compensation expense relating to employees.

About Stemline Therapeutics

Stemline Therapeutics, Inc. is a clinical stage biopharmaceutical company developing novel oncology therapeutics that target cancer stem cells (CSCs) and tumor bulk. Stemline is developing two clinical stage product candidates, SL-401 and SL-701, and preclinical candidates that include SL-801. SL-401 is a targeted therapy directed to the interleukin-3 receptor (IL-3R) present on CSCs and tumor bulk of a wide range of hematologic cancers. Several multicenter clinical trials with SL-401 are currently open in a variety of indications. Patients are currently being enrolled in the expansion stage of the SL-401 pivotal trial in relapsed/refractory blastic plasmacytoid dendritic cell neoplasm (BPDCN). This follows recent completion of the lead-in stage of this trial that enrolled first-line and relapsed/refractory BPDCN and relapsed/refractory acute myeloid leukemia (AML) patients at escalating doses and confirmed the dose and schedule for the current expansion stage. A previous Phase 1/2 trial with SL-401 demonstrated major responses, including complete responses (CRs), in both first-line and relapsed/refractory BPDCN as well as relapsed/refractory AML (Frankel et al. Blood 124, 2014). Clinical studies with SL-401 are also open in additional malignancies including AML in CR with minimal residual disease (MRD) and several high-risk myeloproliferative neoplasms (MPN). SL-701, an immunotherapy designed to activate the immune system to attack tumors, is being developed in adult patients with second-line glioblastoma multiforme (GBM). SL-801, a novel oral small molecule reversible inhibitor of XPO1, is currently being advanced toward investigational new drug (IND) filing for clinical development in a variety of solid and hematologic cancers.
