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 inflammatory diseases at the surface of the eye. 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, pain, redness, itching and other symptoms associated with ocular surface diseases. EBI-005 is currently in Phase 3 clinical development for the treatment of moderate to severe allergic conjunctivitis. In a completed Phase 2 clinical trial, EBI-005 exhibited biological activity in improving the symptoms of late-phase allergic responses in patients with moderate to severe allergic conjunctivitis in a CAPT model.

About EBI-031

Eleven Biotherapeutics’ most advanced preclinical product candidate is EBI-031 for treatment of diabetic macular edema, or DME and uveitis. EBI-031 has been designed and engineered for intravitreal delivery using our 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. We are undertaking the necessary 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.
