CAMBRIDGE, Mass.–(BUSINESS WIRE)–Jul. 19, 2018– AVEO Oncology (NASDAQ: AVEO) today issued the following statement regarding its recentlyrevised guidance on the timing of topline data from the TIVO-3 study, its Phase 3 trial of tivozanib as a third-line treatment for advanced renal cell carcinoma.

“The Company expects to report topline results from the TIVO-3 study in the fourth quarter of 2018, approximately 6-8 weeks after the trial records 255 progression free survival (PFS) events. This change in guidance from the third quarter of 2018 is the result of PFS events occurring slower than forecasted, combined with ten patients being removed or ‘censored’ from the PFS event count. The one-time adjustment in the event count is the result of an administrative error that occurred from counting, as PFS events, the deaths of ten patients who had left the study without documented radiographic progression. These deaths will be counted only as overall survival (OS) events. Per regulatory guidance and the TIVO-3 protocol, among patients who leave the study without documented disease progression, only those who die within eight weeks of their last study assessment and have not started another therapy can be counted as a PFS event. Following the adjustment, and as of yesterday, the PFS event count is 243.”

“Study data remains blinded to the Company and no changes in study assumptions have been made. The administrative error was discovered as part of the data cleaning and review process. The data review process was initiated in an effort to shorten the data analysis period between reaching the 255 PFS events (database lock) and the announcement of topline data. By correcting the administrative error prior to database lock, the intended statistical powering of the study has been unaffected. The Company plans to announce when 255 PFS events have occurred and the topline data analysis for the trial has been initiated.”
