Eleven Biotherapeutics reports financial results and operational highlights for Q1 2014

Eleven Biotherapeutics, Inc. (Nasdaq: EBIO), a clinical-stage biopharmaceutical company discovering and developing protein therapeutics to treat diseases of the eye, today reported financial results and operational highlights for the quarter ended March 31, 2014.

"Eleven Biotherapeutics is off to a strong start in 2014," stated Abbie Celniker, President and Chief Executive Officer. "We are pleased to announce that we completed patient enrollment in the EBI-005 Phase 2 clinical trial for allergic conjunctivitis and are on-track to report top-line clinical data in the fourth quarter of 2014 as planned. In addition, our pivotal Phase 3 clinical study of EBI-005 in dry eye disease continues to enroll patients on schedule, and our plan to initiate a twelve-month safety study with EBI-005 is also on track for the second half of this year."

"Earlier this year, we completed our initial public offering, improving our balance sheet and attracting a number of new shareholders, and strengthened our leadership team with the appointments of ophthalmology industry veterans to our board and management team. We were also pleased by the interest of the medical and scientific community in the data we presented at a number of ophthalmology industry conferences this spring, including clinical data on EBI-005, the first IL-1 (Interleukin-1) signaling inhibitor designed for topical ocular administration, and preclinical data on EBI-029, an IL-6 (Interleukin-6) inhibitor optimized for localized ocular administration in diabetic macular edema."

First Quarter 2014 and Recent Business Highlights:

Pipeline:

• Initiated a pivotal Phase 3 clinical study with EBI-005 in dry eye disease with top-line results expected in early 2015.
• Initiated and completed patient enrollment in a Phase 2 clinical trial of EBI-005 for the treatment of allergic conjunctivitis with top-line results expected in the fourth quarter of 2014.
• Presented at a number of ophthalmology industry conferences including:
  • Association for Research in Vision and Ophthalmology (ARVO) 2014 Annual Meeting, at which Eleven Biotherapeutics researchers gave three poster presentations elaborating on Eleven's understanding of cytokine biology to target the treatment of front and back of eye diseases. These posters included clinical data on EBI-005 demonstrating improvements in signs and symptoms in patients with dry eye disease through IL-1 Inhibition, and preclinical data on EBI-029 demonstrating inhibition of IL-6 as a validated target for treating diabetic macular edema.
  • 2014 American Society of Cataract and Refractive Surgery (ASCRS) Annual Symposium, at which Michael H. Goldstein, M.D., M.B.A., Eleven Biotherapeutics' Vice President of Clinical Research and co-director of the Cornea, External Disease and Cataract Service group at Tufts University/ New England Eye Center, presented Phase 1b/2a clinical data on Eleven's lead product candidate EBI-005 for the treatment of dry eye disease. Dr. Goldstein received the honor of a 'Best Paper in Session' award and was listed in Eye World Today and the ASCRS meeting newspaper.
  • 2014 Ophthalmology Innovation Summit (OIS) @ American Society of Cataract and Refractive Surgery (ASCRS) Annual Meeting, at which Abbie Celniker participated in a session, along with other industry leaders, on the topic of dry eye disease. The participants in the session, who represented a cross section of industry and scientific thought leaders, discussed the role dry eye technologies and therapies play in ophthalmic practice.
  • World Ophthalmology Congress (WOC) 2014, at which Michael Goldstein, M.D., presented on the topic of IL-1 inhibition for dry eye disease and highlighted EBI-005 clinical data as a case study.
  • 10^th Annual Protein and Engineering Summit (PEGS), at which Eleven Biotherapeutics researchers presented data demonstrating the power of Eleven's AMP-Rx platform to design and engineer novel protein therapeutics. Eleven's presentation topics included modulating cytokines to treat front and back of eye disease such as IL-1 inhibition with EBI-005, IL-6 inhibition with EBI-029 and IL-17 inhibition with EBI-028 and designing topical treatments of ocular surface inflammatory disorders, such as EBI-005, to have low immunogenicity potential.

Corporate:

• Completed our initial public offering, with aggregate net proceeds of approximately $50.2 million, net of underwriting discounts and commissions and other offering expenses payable by us.
• Strengthened our leadership team with the appointment of ophthalmic industry veterans, including Paul Chaney as a member of our Board of Directors and Gary Sternberg, M.D., M.B.A., as Executive Vice President Corporate and Business Development.
• Added to the Russell Indexes on March 31, 2014, including the Russell 2000 and Russell 3000 index.

Upcoming Events and Presentations:

• Contact Lens Association of Ophthalmologists (CLAO), June 14, 2014
• International Society of Ophthalmologists (ISOPT), June 19-22, 2014

Financial Results

Revenues were $0.6 million during the quarter ended March 31, 2014 compared to $0 for the quarter ended March 31, 2013 and include amounts from the Thrombogenics collaboration which began in May 2013.

Total operating expenses for the quarter ended March 31, 2014 were $7.8 million compared to $5.4 million for the quarter ended March 31, 2013.

Net cash used in operating activities during the quarter ended March 31, 2014 was $5.0 million compared to $5.4 million for the quarter ended March 31, 2013. Eleven Biotherapeutics held $54.0 million in cash and cash equivalents as of March 31, 2014. We have identified and are planning additional expenditures that we believe will enhance the likelihood of EBI-005's clinical and commercial success. A majority of these additional expenses will be contingent upon positive results from our first Phase 3 clinical study. If we make such expenditures, the Company expects to have sufficient cash and cash equivalents to fund current operations into the first quarter of 2016. This is an update from previous guidance in which cash was forecast to be sufficient into the second half of 2016.

Net loss applicable to common stockholders was $7.7 million, or $0.80 per share, for the quarter ended March 31, 2014, compared to net loss applicable to common stockholders of $6.4 million, or $5.14 per share, for the quarter ended March 31, 2013.
