Stemline Therapeutics Reports Fourth Quarter 2015 Financial Results

March 14, 2016 at 7:31 AM EDT

NEW YORK, March 14, 2016 (GLOBE NEWSWIRE) -- Stemline Therapeutics, Inc. (Nasdaq:STML) today reported financial results for the quarter ended December 31, 2015.

Ivan Bergstein, M.D., Stemline's Chief Executive Officer, commented, "During the fourth quarter, we made significant progress across all three of our development programs. Key achievements included 1) generating and presenting data from our ongoing Phase 2 trial of SL-401 in blastic plasmacytoid dendritic cell neoplasm (BPDCN) which we have designed to support potential registration, 2) treating our first patient in the second stage of our Phase 2 program of SL-701 in advanced brain cancer, and 3) the opening of our IND for SL-801 on schedule. At the American Society of Hematology (ASH) meeting in December, we presented very strong data from our ongoing SL-401 trial in BPDCN, demonstrating a high overall response rate in BPDCN, with multiple complete responses. We are also very pleased with the pace of enrollment in BPDCN, and note that we are tracking in-line with our expectations. We look forward to sharing key clinical and regulatory updates on SL-401 throughout this year."

Dr. Bergstein continued, "We continue to evaluate SL-401 in several additional malignancies that overexpress IL-3R. Specifically, we have single agent trials enrolling AML patients with minimal residual disease and patients with advanced high-risk myeloproliferative neoplasms. We also expect our first clinical studies that combine SL-401 with other therapies will begin this year."

Dr. Bergstein concluded, "Our other pipeline candidates, SL-701 and SL-801, continue to advance. Our SL-701 trial is currently enrolling patients and we expect updates from this program in the second half of the year. The SL-801 IND is open, and we are on track to treat our first patient this quarter. With our strong cash position, we believe we have sufficient financial resources to achieve significant clinical and regulatory milestones this year and beyond."

Fourth Quarter 2015 Financial Results Review

Stemline ended the fourth quarter of 2015 with $97.5 million in cash, cash equivalents and investments, as compared to $104.0 million as of September 30, 2015, which reflects a cash burn of $6.5 million for the quarter. The company ended the fourth quarter of 2015 with 18.2 million shares outstanding.

For the fourth quarter of 2015, Stemline had a net loss of $10.2 million, or $0.58 per share, compared with a net loss of $6.9 million, or $0.53 per share, for the same period in 2014. The net loss for full year 2015 was $37.2 million, or $2.15 per share, as compared with a net loss of $28.8 million, or $2.23 per share, in the prior year.

Research and development expenses were $7.9 million for the fourth quarter of 2015, which reflects an increase of $2.8 million, or 56%, compared with $5.1 million for the fourth quarter of 2014. The increase in expenses during the current quarter was primarily attributable to the ramp up in our clinical trial activities for SL-401 and SL-801.

General and administrative expenses were $2.6 million for the fourth quarter of 2015, which reflects an increase of $0.6 million, or 30%, compared with $2.0 million for the fourth quarter of 2014. The increase in expenses during the current quarter was primarily attributable to an increase in compensation expense relating to administrative employees.

About Stemline Therapeutics
Stemline Therapeutics, Inc. is a clinical stage biopharmaceutical company developing novel oncology therapeutics. Stemline is developing three product candidates, SL-401, SL-701, and SL-801. A potentially pivotal Phase 2 trial with SL-401 is currently enrolling patients with blastic plasmacytoid dendritic cell neoplasm (BPDCN). Data from the initial stage of this ongoing trial demonstrated high overall response rates, with multiple complete responses (CRs) and patients bridged to transplant. Patients continue to be followed for overall response, progression free survival (PFS) and overall survival (OS), and new patients are also enrolling into the study. Clinical studies with SL-401 are also enrolling patients with additional malignancies including acute myeloid leukemia (AML) in CR with minimal residual disease (MRD) and high-risk myeloproliferative neoplasms (MPN). A clinical study with SL-701, an immunotherapy designed to activate the immune system to attack tumors, is currently enrolling adult patients with second-line glioblastoma multiforme (GBM). SL-801, a novel oral small molecule reversible inhibitor of XPO1, has an open IND and is being advanced into clinical trials in patients with advanced solid cancers.
