"2017 was a year of significant developments for our company, and as we look ahead, I am highly encouraged by what we have already achieved in 2018. Vicinium, our lead product candidate, holds significant potential in treating a range of cancers, and is well underway in a registration trial for people with non-muscle invasive bladder cancer," said Stephen Hurly, president and chief executive officer of Eleven Biotherapeutics. "We recently completed enrollment in our Phase 3 VISTA trial, and we are pleased that initial data from the first patients in the VISTA trial were selected for an oral presentation at the American Urological Association Annual Meeting. 2018 is set to be a transformative year, and with the completion of our recent equity financing, we are capitalized to continue advancing Vicinium. We look forward to assessing its efficacy and safety in NMIBC, and exploring opportunities to expand its utility in other indications and in combination regimens."
Recent Pipeline and Corporate Highlights
On March 23, 2018, Eleven Biotherapeutics closed a $10.0 million equity financing priced at-the-market. This financing, coupled with the proceeds from the company’s $8.0 million public offering completed in November 2017, extends the company’s cash runway into the first quarter of 2019 based on its current operating plan.
In March 2018, Eleven Biotherapeutics announced that enrollment was completed in the company’s Phase 3 VISTA trial evaluating its lead product candidate, Vicinium, for the treatment of patients with non-muscle invasive bladder cancer (NMIBC) who have been previously treated with bacillus Calmette-Guérin (BCG).
In December 2017, a trial at the US National Cancer Institute (NCI) of Vicinium in combination with AstraZeneca’s immune checkpoint inhibitor, Imfinzi (durvalumab), for the treatment of NMIBC opened.
In September 2017, Eleven Biotherapeutics completed the manufacturing of all Vicinium necessary for its ongoing trials.

Present Preclinical Data at AACR (Free AACR Whitepaper): Eleven Biotherapeutics will present preclinical data from its deBouganin program at the 2018 American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting during two poster sessions. The company’s systemically administered product candidates are designed using its proprietary de-immunized variant of the plant-derived cytotoxin bouganin, deBouganin. Details of the presentations are as following:
Poster Title: VB6-845d Tumor Cell Killing Elicits Biologic Features of Immunogenic Cell Death
Date and Time: April 16, 2018 from 1:00 to 5:00 p.m. CT
Poster Title: Engineering and Characterization of Anti-PSMA Humabody-DeBouganin Fusion Proteins
Date and Time: April 18, 2018 from 8:00 a.m. to 12:00 p.m. CT
Present Data from Phase 3 VISTA Trial at AUA Annual Meeting: Eleven Biotherapeutics will present the first, topline data from its Phase 3 VISTA trial of Vicinium in patients with NMIBC who have been previously treated with BCG during a plenary session at this year’s American Urological Association Annual Meeting being held in San Francisco. The data being presented are three-month data from an initial 75 patients in the trial. Details of the presentation are as follows:
Presentation Title: Phase 3 Study of Vicinium in BCG-Unresponsive Non-Muscle Invasive Bladder Cancer: Initial Results
Date and Time: Monday, May 21, 2018 at 11:00 a.m. PT
Fourth Quarter and Full-Year 2017 Financial Results
Cash Position: Cash and cash equivalents were $14.7 million as of December 31, 2017, compared to $25.3 million as of December 31, 2016, a decrease of $10.6 million, which was primarily driven by $17.6 million in cash used by operating activities plus, $0.1 million in capital expenditures, partially offset by $7.1 million in cash provided through the November 2017 underwritten public offering.
Revenue: No revenue was recognized during the three months ended December 31, 2017, compared to $0.8 million for the same three-month period in 2016. Revenue was $0.4 million for the twelve months ended December 31, 2017, compared to $30.0 million for the same period in 2016. The decrease was primarily due to a decrease in license revenue as we recognized the upfront license fee and development milestone payment under the license agreement with Roche, relating to the execution of the license agreement and the successful submission of the IND application for EBI-031 during 2016, as well as a decrease in collaboration revenue from a terminated collaboration.
R&D Expenses: Research and development expenses were $3.1 million for the three months ended December 31, 2017, compared to $2.8 million for the same period in 2016. For the twelve months ended December 31, 2017 research and development expenses were $12.5 million compared to $13.5 million for the 2016 fiscal year. The decrease of $1.0 million was primarily due to a decrease in EBI-031 related development expenses of $3.0 million due to the license agreement with Roche in which Roche is responsible for all on-going development expenses, as well as a decrease of $1.7 million of isunakinra-related development expenses, which development activities are no longer ongoing. These decreases were partially offset by increases in Vicinium-related development

expenses of $5.4 million, since the company’s acquisition of Viventia Bio Inc. (Viventia) in September 2016.
G&A Expenses: General and administrative expenses were $2.0 million for the three months ended December 31, 2017, compared to $2.8 million for the same period in 2016. For the twelve months ended December 31, 2017 general and administrative expenses were $8.1 million compared to $14.7 million for fiscal 2016. The decrease of $6.7 million was primarily due to a reduction of professional fees as well as salaries and related costs for personnel, including stock-based compensation. For the year ended December 31, 2016, the company had higher professional fees related to the license agreement with Roche, the company’s 2016 review of strategic alternatives and the acquisition of Viventia. In addition, for the year ended December 31, 2016, the company recorded higher severance costs related to the acquisition of Viventia.
Net Income (Loss): Net loss was $6.6 million, or $0.22 per share, for the three months ended December 31, 2017, compared to net loss of $3.5 million, or $0.15 per share, for the same period in 2016. Net loss was $29.0 million, or $1.11 per share, for the twelve months ended December 31, 2017, compared to net income of $1.9 million, or $0.09 per share, for the same period in 2016. Fiscal 2016 was benefited by approximately $30.0 million in revenue under the company’s license agreement with Roche while no comparable revenue was recognized during fiscal 2017.
Financial Guidance: Following Eleven Biotherapeutics’ recent $10.0 million equity financing in March 2018, the company expects to have capital to fund its current operating plans into the first quarter of 2019; however, we have based this estimate on assumptions that may prove to be wrong, and our capital resources may be utilized faster than we currently expect.
About Vicinium
Vicinium, Eleven Biotherapeutics’ lead product candidate, is a next-generation antibody-drug conjugate (ADC) developed using the company’s proprietary Targeted Protein Therapeutics platform. Vicinium is comprised of a recombinant fusion protein that targets epithelial cell adhesion molecule (EpCAM) antigens on the surface of tumor cells to deliver a potent protein payload, Pseudomonas Exotoxin A (ETA). Vicinium is constructed with a stable, genetically engineered peptide linker to ensure the payload remains attached until it is internalized by the cancer cell, which is believed to decrease the risk of toxicity to healthy tissues, thereby improving its safety. In prior clinical studies conducted by Eleven Biotherapeutics, EpCAM has been shown to be overexpressed in non-muscle invasive bladder cancer (NMIBC) cells with minimal to no EpCAM expression observed on normal bladder cells. Eleven Biotherapeutics is currently conducting the Phase 3 VISTA trial, designed to support the registration of Vicinium for the treatment of NMIBC in patients who have previously received two courses of bacillus Calmette-Guérin (BCG) and whose disease is now BCG-unresponsive. Topline, three-month data from the trial are expected in mid-2018. Additionally, Eleven Biotherapeutics believes that Vicinium’s cancer cell-killing properties promote an anti-tumor immune response that may potentially combine well with immuno-oncology drugs, such as checkpoint inhibitors. The activity of Vicinium in BCG-unresponsive NMIBC is also being explored at the US National Cancer Institute in combination with AstraZeneca’s immune checkpoint inhibitor durvalumab.
