Eleven Biotherapeutics, Inc. (the “Company”) was unable to file its quarterly report on Form 10-Q for the period ended September 30, 2017 by the prescribed date without unreasonable effort or expense. Additional time is needed to finalize its accounting related to the Company’s acquisition of Viventia Bio, Inc. (“Viventia”) in September 2016 and the fair value of the contingent consideration liability as of September 30, 2017. The Company expects to file the Form 10-Q no later than the fifth calendar day following the prescribed due date, as permitted by Rule 12b-25.

	Stephen A. Hurly	617	444-8550
	(Name)	(Area Code)	(Telephone Number)

(2)	Have all other periodic reports required under Section 13 or 15(d) of the Securities Exchange Act of 1934 or Section 30 of the Investment Company Act of 1940 during the preceding 12 months or for such shorter period that the registrant was required to file such report(s) been filed? If answer is no, identify report(s).

			x Yes o No

(3)	Is it anticipated that any significant change in results of operations from the corresponding period for the last fiscal year will be reflected by the earnings statements to be included in the subject report or portion thereof?

			x Yes o No

	If so, attach an explanation of the anticipated change, both narratively and quantitatively, and, if appropriate, state the reasons why a reasonable estimate of the results cannot be made.

For the three months ended September 30, 2017, the Company expects to report that there was no revenue compared to $28.7 million in revenue for the three months ended September 30, 2016. In August 2016, the Company recognized the upfront license fee and the development milestone payment under its license agreement (the “License Agreement”) with F. Hoffmann-La Roche Ltd and Hoffmann-La Roche Inc. (collectively, “Roche”), relating to the execution of the License Agreement and the successful submission of an investigation new drug application for its monoclonal antibody EBI-031.

The Company also expects to report that general and administrative expenses were $1.6 million for the three months ended September 30, 2017 compared to $6.4 million for the three months ended September 30, 2016. The decrease of $4.8 million was due primarily to a reduction in professional fees as well as salaries and related costs for personnel, including stock-based compensation. For the three months ended September 30, 2016, the Company had higher professional fees compared to the 2017 period related to the License Agreement with Roche, its 2016 review of strategic alternatives and its acquisition of Viventia in September 2016. In addition, for the three months ended September 30, 2016, the Company paid higher severance costs related to its acquisition of Viventia compared to the 2017 period.

The Company expects to report that research and development expenses for the three months ended September 30, 2017 were $3.6 million as compared to $2.8 million for the three months ended September 30, 2016. This increase was due primarily to higher costs incurred for the Company’s ongoing Phase 3 clinical trial for Vicinium in patients with non-muscle invasive bladder cancer that were partially offset by the absence of costs associated with the monoclonal antibody EBI-031licensed to Roche in 2016 and lower compensation related costs.

As reference above in Part III, the Company intends to make certain acquisition accounting adjustments in its financial statements in connection with finalization of the accounting for the acquisition of Viventia, as well as the fair value of the contingent consideration liability as of September 30, 2017, all of which have not yet been completed. A reasonable estimate of the results of operations for the Company for the three months ended September 30, 2017 cannot be made until all accounting relating to the acquisition of Viventia and the estimate of the fair value of the contingent consideration as of September 30, 2017 have been finalized, and we have completed preparation of financial statements for inclusion in the Form 10-Q.
