Eleven Biotherapeutics Reports Third Quarter 2014 Financial Results

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

"We have made good progress advancing our lead product candidate, EBI-005, since the second quarter of this year. We are encouraged by the Phase 2 top-line safety and efficacy results for EBI-005 in patients with moderate to severe allergic conjunctivitis, as we believe these data further validate EBI-005 as a clinically active anti-inflammatory ocular agent,” said Abbie Celniker, PhD, President and Chief Executive Officer. “Additionally, we recently completed patient enrollment in our first pivotal Phase 3 study of EBI-005 in patients with dry eye disease and expect to report top-line results of that trial in the second quarter of 2015.”

Recent Business Highlights:

• Reported top-line results from our proof of concept Phase 2 clinical trial of EBI-005 in patients with moderate to severe allergic conjunctivitis where we compared two models of the disease. In a modified CAPT (conjunctival allergen provocation test) model, patients treated with EBI-005 showed statistically significant improvements in a number of clinically meaningful symptoms that were secondary and exploratory endpoints in this trial, including reduction of ocular itching, nasal symptoms and tearing. Importantly, EBI-005 was generally well-tolerated, with no treatment-related serious adverse events and no drug-specific antibodies detected. This Phase 2 study did not meet the primary endpoint of reduction in mean ocular itching in patients treated with EBI-005 compared to vehicle-control in a modified environmental exposure chamber model. These data will help us to determine our path forward with EBI-005 as a potential new treatment option for patients with moderate to severe allergic conjunctivitis.
• Completed patient enrollment in the OASIS study (A Multi-Center, Double-Masked, Randomized, Controlled, Efficacy and Safety Study of EBI-005 5 mg/mL Topical Ophthalmic Solution Versus Vehicle Control in Subjects with Moderate to Severe Dry Eye Disease), our first pivotal Phase 3 clinical study for EBI-005 in patients with dry eye disease. Over half of the subjects have completed the study, and we expect to report top-line results in the second quarter of 2015.
• Granted a U.S. patent for EBI-005 which contains both composition-of-matter and methods of use claims, which expires in 2031.
• Appointed industry veteran Wendy L. Dixon, PhD, former Chief Marketing Officer and President of Global Marketing for Bristol Myers Squibb, to our Board of Directors.

Third Quarter 2014 Financial Results

• Revenue: Revenue was $0.5 million for the three months ended September 30, 2014, compared to $0.6 million for the same period in 2013.
• R&D Expenses: Research and development expenses were $8.9 million for the three months ended September 30, 2014 compared to $3.4 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 $2.3 million for the three months ended September 30, 2014, compared to $0.8 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 2014 and increased stock-based compensation expense.
• Net Loss: Net loss applicable to common stockholders was $10.7 million, or $0.66 per share, for the three months ended September 30, 2014, compared to net loss applicable to common stockholders of $4.7 million, or $3.39 per share, for the same period in 2013.
• Cash and Cash Equivalents: Cash and cash equivalents were $35.9 million as of September 30, 2014. We believe that our cash and cash equivalents as of September 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, a novel, topically-administered interleukin-1 (IL-1) receptor blocker in development as a protein therapeutic for dry eye disease and allergic conjunctivitis. The EBI-005 program is based on the role that elevated levels of the inflammatory cytokine IL-1 play in the initiation and maintenance of the inflammation and pain associated with dry eye disease and the itching and other symptoms associated with allergic conjunctivitis. EBI-005 has been evaluated in a Phase 2 study in patients with moderate to severe allergic conjunctivitis and is currently being evaluated in a pivotal Phase 3 study in dry eye disease.
