Eleven Biotherapeutics Reports Second Quarter 2014 Financial Results

Eleven Biotherapeutics, Inc. (Nasdaq: EBIO), a clinical-stage biopharmaceutical company discovering and developing protein therapeutics to treat diseases of the eye, today reported business highlights and financial results for the second quarter ended June 30, 2014.

“We made significant progress advancing our clinical pipeline of novel therapeutics for ocular disease this quarter, including EBI-005, our lead product candidate in development as one of the first topically administered proteins for the treatment of inflammatory ocular surface disease,” said Abbie Celniker, President and Chief Executive Officer. “Our pivotal Phase 3 clinical study of EBI-005 in dry eye disease is continuing to enroll patients and we plan to initiate a twelve-month safety study with EBI-005 later this year. We look forward to continuing to advance this program towards the market, and reiterate our intention to file a Biologic License Application (BLA) with the U.S. Food and Drug Administration (FDA) for EBI-005 in the second half of 2016 for dry eye disease.”

Pipeline Highlights:

• Remain on track to report top-line data for our proof of concept Phase 2 clinical trial of EBI-005 in allergic conjunctivitis in the fourth quarter of 2014.
• On track to report top-line Phase 3 clinical data for EBI-005 in dry eye disease in early 2015.
• Continue to make progress advancing development of EBI-029 for back of the eye disease, including diabetic macular edema.

Second Quarter 2014 Financial Results

• Revenues: Revenues were $0.8 million for the three months ended June 30, 2014, compared to $0.2 million for the same period in 2013. This increase was primarily due to revenue recognized from the ThromboGenics collaboration which began in May 2013.
• R&D Expenses: Research and development expenses were $6.8 million for the three months ended June 30, 2014 compared to $2.7 million for the same period in 2013. This increase was primarily due to EBI-005 related development expenses.
• G&A Expenses: General and administrative expenses were $2.1 million for the three months ended June 30, 2014, compared to $0.9 million for the same period in 2013. This increase was primarily due to increased operating costs related to operating as a public company since February 2013 and increased stock-based compensation expense.
• Operating Loss: Net loss applicable to common stockholders was $8.1 million, or $0.51 per share, for the three months ended June 30, 2014, compared to net loss applicable to common stockholders of $4.6 million, or $3.44 per share, for the same period in 2013.
• Cash and Cash Equivalents: Cash and cash equivalents were $45.0 million as of June 30, 2014. We believe that our cash and cash equivalents as of June 30, 2014 will enable us to fund our operating expenses, debt service obligations and capital expenditure requirements into the first quarter of 2016.

About EBI-005

Eleven Biotherapeutics’ most advanced product candidate is EBI-005, which was designed, engineered and generated using the Company’s AMP-Rx platform and is being developed as a topical treatment for dry eye disease and allergic conjunctivitis. In 2013, Eleven Biotherapeutics completed a Phase 1b/2a clinical trial of EBI-005 in patients with moderate to severe dry eye disease. The EBI-005 program is based on the role that elevated levels of the inflammatory cytokine interleukin-1, or IL-1, play in the initiation and maintenance of the inflammation and pain associated with dry eye disease and the redness and itching associated with allergic conjunctivitis. EBI-005 is currently being evaluated in a pivotal Phase 3 clinical study in subjects with dry eye disease and a Phase 2 clinical study in subjects with allergic conjunctivitis.
