Story continues below

Syndax Pharmaceuticals, Inc., a Delaware corporation (“we,” “us,” or the “Company”) announces today that ECOG-ACRIN Cancer Research Group, the sponsor of our Phase 3 registration trial of entinostat plus exemestane in advanced hormone receptor positive, human epidermal growth factor receptor 2 negative (HR+, HER2-) breast cancer, E2112, notified us in advance of their October 24 – 26 biannual group meeting that the trial has passed its fifth and final interim overall survival (OS) analysis.  The E2112 trial design was informed by the Phase 2b ENCORE 301 trial, the results of which led to entinostat’s Breakthrough Therapy designation in HR+, HER2- breast cancer, in which patients receiving the entinostat/exemestane combination demonstrated a strong OS benefit.  

The trial will now continue until the final OS analysis, which will happen when 410 deaths from among the 608 patients enrolled have occurred.  Based upon our modeling of the assumed event rate, we expect this final analysis to occur in the second quarter of 2020.  We have included in this filing a revised corporate presentation containing the update to the E2112 trial.

A copy of the above referenced presentation is furnished as Exhibit 99.1 to this Current Report on Form 8-K. This information, including the information contained in the presentation furnished as Exhibit 99.1, shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, and is not incorporated by reference into any of the Company’s filings, whether made before or after the date hereof, regardless of any general incorporation language in any such filing.
