CAMBRIDGE, Mass.--(BUSINESS WIRE)--Feb. 26, 2015-- Sarepta Therapeutics, Inc. (NASDAQ:SRPT), a developer of innovative RNA-targeted therapeutics, today reported financial results for the three months and year ended December 31, 2014, and provided an update of recent corporate developments.

“Last month we released 168 week data from our Phase IIb study of eteplirsen. We believe the long-term safety of our drug with the continued ambulation and stability of pulmonary function in these boys are encouraging considering the length of follow up and the advancing age of the boys,” said Chris Garabedian, president and chief executive officer. “We are actively collecting and analyzing the additional datasets requested by the FDA and plan to meet with the FDA in the second quarter to ensure that we are aligned with their expectations for an acceptable NDA filing. We continue to work towards a complete NDA submission by mid-year 2015.”

Financial Results

For the fourth quarter of 2014, Sarepta reported a non-GAAP net loss of $38.6 million, or $0.94 per share, compared to a non-GAAP net loss of $29.1 million for the fourth quarter of 2013, or $0.77 per share. The incremental loss of $9.5 million was primarily the result of increased operating expenses as well as a decrease in revenue from the Company’s government contracts.

On a GAAP basis, the net loss for the fourth quarter of 2014 was $44.4 million, or $1.08 per share (including $5.8 million of stock-based compensation and restructuring expenses), compared to a net loss of $8.8 million, or $0.23 per share (including $3.7 million of stock-based compensation and restructuring expenses) for the fourth quarter of 2013. The increase in net loss is primarily the result of a $24.0 million decrease in gain on change in warrant valuation, an increase of $9.3 million in operating expenses as a result of corporate growth and a decrease of $2.6 million in revenue from the Company’s government contracts.

Revenue for the fourth quarter of 2014 decreased by $2.6 million primarily due to the July 2014 expiration of the Marburg portion of the Company’s Ebola-Marburg U.S. government contract.

Non-GAAP research and development expenses were $28.4 million for the fourth quarter of 2014, compared to $23.6 million for the fourth quarter of 2013, an increase of $4.8 million. GAAP research and development expenses were $30.8 million for the fourth quarter of 2014 (including $2.4 million of stock-based compensation and restructuring expenses), compared to $25.1 million for the fourth quarter of 2013 (including $1.5 million of stock-based compensation and restructuring expenses), an increase of $5.7 million.

Non-GAAP general and administrative expenses were $10.5 million for the fourth quarter of 2014, compared to $8.2 million for the fourth quarter of 2013, an increase of $2.3 million. GAAP general and administrative expenses were $13.9 million for the fourth quarter of 2014 (including $3.4 million of stock-based compensation expense), compared to $10.4 million for the fourth quarter of 2013 (including $2.2 million of stock-based compensation and restructuring expenses), an increase of $3.5 million.

The increase in operating expenses was primarily caused by research and development personnel growth, increased clinical activity in connection with our DMD programs and increased consulting and professional fees in the normal course of business.

For the year ended December 31, 2014, the operating loss was $133.8 million, compared to an operating loss of $90.3 million for the prior year. The $43.5 million increase was the result of a $21.3 million increase in research and development expenses and a $17.7 million increase in general and administrative expenses as well as a $4.5 million decrease in revenue from the Company’s government contracts.

Revenue for the year ended December 31, 2014 decreased to $9.8 million from $14.2 million for the year ended December 31, 2013 primarily due to the July 2014 expiration of the Marburg portion of the Company’s Ebola-Marburg U.S. government contract.

Research and development expenses were $94.2 million for the year ended December 31, 2014, compared to $72.9 million for the prior year, an increase of $21.3 million. The increase was primarily driven by preparation for the potential launch of eteplirsen, if market approval is obtained, as well as the advancement of our early- and late-stage research and development pipeline.

General and administrative expenses for the year ended December 31, 2014 were $49.3 million, compared to $31.6 million for the prior year, an increase of $17.7 million. The increase was primarily due to increased personnel costs, professional services and facility-related expenses.

The Company had $211.1 million in cash, cash equivalents, short-term investments and restricted cash as of December 31, 2014 compared to $264.9 million as of December 31, 2013, a decrease of $53.8 million. The decrease was primarily driven by the use of cash to fund the Company’s ongoing operations, offset by the net proceeds received from the exercises of warrants and stock options and the Company’s public offering in April 2014. Guidance on non-GAAP operating loss for 2015 will be provided during the first quarter earnings call.

In addition to the GAAP financial measures set forth in this press release, the Company has included certain non-GAAP measurements: non-GAAP research and development expenses, non-GAAP general and administrative expenses, non-GAAP operating expense adjustments, non-GAAP net loss, and non-GAAP basic and diluted net loss per share, which present operating results on a basis adjusted for certain items. The Company uses these non-GAAP measures as key performance measures for the purpose of evaluating performance internally. The Company also believes these non-GAAP measures provide the Company’s investors with useful information regarding the Company’s historical operating results. These non-GAAP measures are not intended to replace the presentation of the Company’s financial results in accordance with GAAP. Use of the terms non-GAAP research and development expenses, non-GAAP general and administrative expenses, non-GAAP operating expense adjustments, non-GAAP net loss, and non-GAAP basic and diluted net loss per share may differ from similar measures reported by other companies. All relevant non-GAAP measures are reconciled from their respective GAAP measures in the attached table "Reconciliation of GAAP to Non-GAAP Net Loss."

Recent Corporate Developments

Duchenne Muscular Dystrophy Program

--Presented 168 week data from Study 202, a long-term Phase IIb extension study of eteplirsen in patients with Duchenne muscular dystrophy (DMD). Results through more than three years of treatment showed continued stability of respiratory muscle function, as assessed by pulmonary function tests. Results of the 6 minute walk test showed continued ambulation across all patients evaluable on the test, however all patients showed a decline in distance walked on this measure since the week 144 timepoint.

--Announced dosing in an open-label study, 4658-204 (Study 204), of eteplirsen in non-ambulant patients with DMD. The study, which is being conducted at several sites across the United States and is designed to evaluate the safety of eteplirsen over 96 weeks of dosing, will include approximately 20 patients who have genotypes amenable to exon 51 skipping.

--Announced dosing in an open-label confirmatory study, 4658-301 (PROMOVI), of eteplirsen in ambulant patients with DMD. The study, which is being conducted at 39 sites across the United States and is designed to evaluate the efficacy and safety of eteplirsen in patients over 48 weeks of dosing, will include up to 80 boys, aged 7-16 years, with genotypes amenable to exon 51 skipping.

--Announced dosing in first European Phase I/II Study of SRP-4053 to assess the safety, tolerability, efficacy, and pharmacokinetics in DMD patients with genotypes amenable to exon 53 skipping. The study is being conducted at four sites in Europe under a consortium agreement between Sarepta and various European hospitals, institutions, and scientists established to conduct the study and which is funded in part by the European Union’s Seventh Programme for research, technological development, and demonstration under grant agreement No. 305370.

Infectious Diseases Program-

--Published results from a study done in collaboration with the U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID) on the efficacy of Sarepta’s PMO, AVI-7537, against the Ebola virus in Rhesus monkeys. The study demonstrated 75% effectiveness across the infected population treated with AVI-7537 compared to 0% survival in the control group.
