MSTX Mast Therapeutics, Inc. (delisted)

SAN DIEGO, Nov. 12, 2015 /PRNewswire/ -- Mast Therapeutics, Inc. (NYSE MKT: MSTX), a clinical-stage biopharmaceutical company leveraging its molecular adhesion and sealant technology (MAST) platform to develop novel therapies for sickle cell disease, heart failure and stroke, today reported financial results for the quarter ended September 30, 2015.

"During the third quarter, we continued to make significant progress with our clinical development of vepoloxamer," stated Brian M. Culley, Chief Executive Officer. "We recently surpassed the 80% enrollment mark in our Phase 3 'EPIC' study in sickle cell disease, we enrolled the first patient in our open-label, repeat-exposure EPIC-extension study, and we initiated a Phase 2 study of vepoloxamer in chronic heart failure with a new formulation."

"Additionally, the two Phase 2a studies of AIR001 in patients with heart failure with preserved ejection fraction (HFpEF) continue to enroll patients and we look forward to sharing interim and complete data from those clinical studies in coming months," continued Mr. Culley.

Third Quarter 2015 Operating Results

The Company's net loss for the third quarter of 2015 was $9.9 million, or $0.06 per share (basic and diluted), compared to a net loss of $7.9 million, or $0.06 per share (basic and diluted), for the same period in 2014.

Research and development (R&D) expenses for the third quarter of 2015 were $7.3 million, an increase of $1.9 million, or 36%, compared to $5.4 million for the same period in 2014. The increase was due primarily to increases of $1.8 million in external nonclinical study fees and expenses and a $0.2 million in external clinical study fees and expenses, offset by a $0.1 million decrease in personnel costs and share-based compensation expense. The $1.8 million increase in external nonclinical study fees and expenses was due primarily to an increase in research-related manufacturing costs for vepoloxamer.

Selling, general and administrative (SG&A) expenses of $2.5 million for the third quarter of 2015 were consistent with the same period in 2014.

Year-to-Date Financial Results

The Company's net loss for the nine months ended September 30, 2015 was $29.7 million, or $0.18 per share (basic and diluted), compared to a net loss of $21.4 million, or $0.19 per share (basic and diluted), for the same period in 2014.

R&D expenses for the nine months ended September 30, 2015 were $21.1 million, an increase of $6.6 million, or 46%, compared to $14.5 million for the same period in 2014. The increase was due primarily to a $4.1 million increase in external nonclinical study fees and expenses, a $2.2 million increase in external clinical study fees and expenses and a $0.2 million increase in personnel expenses. 

The $4.1 million increase in external nonclinical study fees and expenses was due primarily to a $3.8 million increase in research-related manufacturing costs for vepoloxamer and a $0.3 million increase in research-related manufacturing costs for AIR001. The $2.2 million increase in external clinical study fees and expenses was due primarily to increases of $2.7 million in EPIC study costs and $0.4 million in costs for our Phase 2 study of vepoloxamer in heart failure, offset by decreases of $0.5 million in AIR001 clinical study costs and $0.5 million in costs for the discontinued Phase 2 study of vepoloxamer in acute limb ischemia. 

SG&A expenses for the nine months ended September 30, 2015 were $8.4 million, an increase of $1.3 million, or 19%, compared to $7.1 million for the same period in 2014. This increase was due primarily to a $0.7 million increase in personnel costs and a $0.5 million increase in professional and consulting fees.

The Company recognized a $0.5 million bargain purchase gain during the nine months ended September 30, 2014 associated with its acquisition of Aires, which was included in other income.

Among the factors that could cause or contribute to material differences between the Company's actual results and the expectations indicated by the forward-looking statements are risks and uncertainties that include, but are not limited to: the uncertainty of outcomes in ongoing and future studies of the Company's product candidates and the risk that its product candidates, including vepoloxamer, may not demonstrate adequate safety, efficacy or tolerability in one or more such studies, including EPIC and the Phase 2 study of vepoloxamer in chronic heart failure; delays in the commencement or completion of clinical studies, including as a result of difficulties in obtaining regulatory agency agreement on clinical development plans or clinical study design, opening trial sites, enrolling study subjects, manufacturing sufficient quantities of clinical trial material, being subject to a "clinical hold," and/or suspension or termination of a clinical study, including due to patient safety concerns or lack of funding; the risk that, even if planned clinical studies are successful, the FDA or other regulatory agencies may determine they are not sufficient to support a new drug application; the potential that, even if clinical studies of a product candidate in one indication are successful, clinical studies in another indication may not be successful; the potential for additional nonclinical or clinical studies to be required prior to initiation of a planned clinical study; the Company's reliance on contract research organizations (CROs), contract manufacturing organizations (CMOs), and other third parties to assist in the conduct of important aspects of development of its product candidates, including clinical studies, manufacturing, and regulatory activities for its product candidates, and that such third parties may fail to perform as expected; the risk that the Company may be required to repay its outstanding debt obligations at a time that could be detrimental to its financial condition, operations and/or business strategy; the Company's ability to obtain additional funding on a timely basis or on acceptable terms, or at all; the potential for the Company to delay, reduce or discontinue current and/or planned development activities, including clinical studies, partner its product candidates at inopportune times or pursue less expensive but higher-risk and/or lower return development paths if it is unable to raise sufficient additional capital as needed; the risk that, even if the Company successfully develops a product candidate in one or more indications, it may not realize commercial success and may never achieve profitability; the risk that the Company is not able to adequately protect its intellectual property rights, through patents or otherwise, and prevent competitors from duplicating or developing equivalent versions of its product candidates or that the use or manufacture of its products or product candidates infringe the proprietary rights of others; and other risks and uncertainties more fully described in the Company's press releases and periodic filings with the Securities and Exchange Commission.
