CAMBRIDGE, Mass.--(BUSINESS WIRE)--Eleven Biotherapeutics, Inc. (NASDAQ: EBIO), a clinical-stage biopharmaceutical company discovering and developing protein therapeutics to treat diseases of the eye, today announced top-line results from the Phase 3 clinical trial of its lead drug candidate, isunakinra (EBI-005), for the treatment of severe allergic conjunctivitis. In this trial, there were no statistically significant differences between the isunakinra treated group and the vehicle control group on the primary endpoint of ocular itching or on any secondary endpoints. Isunakinra was generally well tolerated, with 94% of the patients completing the trial and there were no serious adverse events reported.
The multi-center, double-masked, randomized, vehicle controlled Phase 3 clinical trial was designed to evaluate the safety and efficacy of isunakinra for up to four weeks in patients with moderate to severe allergic conjunctivitis in an environmental setting. A total of 258 patients were randomized 1:1 to receive treatment with isunakinra or with vehicle control.
“We are disappointed that isunakinra failed to meet its primary endpoint, and based on these overall results we see no immediate path forward in allergic conjunctivitis,” said Abbie Celniker, PhD, President and CEO of Eleven Biotherapeutics. “Our efforts will be focused on submitting an investigational new drug application (IND) for EBI-031 in diabetic macular edema in the first half of 2016. In addition, we plan to provide an update on our corporate strategy later this quarter during our 2015 year-end financial results conference call.”
Michael Goldstein, MD, Chief Medical Officer of Eleven Biotherapeutics commented, “Despite this outcome, we plan to continue to assess interleukin-1 (IL-1) genotyping in ocular surface diseases by evaluating data from patient subsets in this clinical trial identified to be high producers of IL-1.”
As of December 31, 2015, Eleven had approximately $36.1 million of cash and cash equivalents. As a result of the outcome of this trial, Eleven is required to fund a cash collateral account with Silicon Valley Bank in an amount equal to approximately $15.1 million, representing the outstanding amounts under its loan agreement with Silicon Valley Bank. Eleven Biotherapeutics currently expects its unrestricted cash and cash equivalents will enable the Company to fund its operating plans into the fourth quarter of 2016.
Eleven Biotherapeutics' most advanced preclinical product candidate is EBI-031 for treatment of diabetic macular edema, or DME, and uveitis. EBI-031 was designed and engineered for intravitreal delivery using the Company’s AMP-Rx platform. EBI-031 is a potent blocker of both free IL-6 and IL-6 complexed to the soluble IL-6 receptor (IL-6R) and has demonstrated a longer vitreal retention time in preclinical models than antibodies and antibody like molecules approved for intravitreal injection. The Company is undertaking manufacturing development work and nonclinical safety studies to support the submission of an investigational new drug application, or IND, to the FDA in the first half of 2016 for the purpose of conducting clinical trials of EBI-031 in DME and uveitis.
