Eleven Biotherapeutics, Inc. received the results of a pre-specified, masked, sample size reassessment of our first pivotal Phase 3 clinical trial of EBI-005 in dry eye disease. Based on this reassessment, we will continue to target approximately 650 patients for randomization in this trial as planned.
The sample size reassessment was conducted by a contract research organization, or CRO, on a masked basis of the first one-third of the randomized patients when they had completed 12 weeks of masked treatment with EBI-005 or placebo-control. The reassessment was conducted to determine if the observed variability of the clinical response in the ongoing Phase 3 trial was greater than the variability we assumed based on the results of our Phase 1b/2a trial, and whether an increase in the number of patients randomized in this trial would be sufficient to adjust for the increase in variability.
The CRO only reported the conclusion of the sample size reassessment to maintain our current target of randomizing approximately 650 subjects in this study.
Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
