Item 8.01          Other events

Agenus Inc. announced final results from a single-arm, multi-institutional, open-label, Phase 2 study showing that patients with newly diagnosed glioblastoma multiforme (GBM) who received Agenus’ Prophage autologous cancer vaccine added to the standard of care treatment, lived nearly twice as long as expected.  In this Phase 2 study, 50% of the patients lived for two years, an encouraging result for a cancer that often kills patients within one year 1-7.  Prophage patients demonstrated a median overall survival of approximately 24 months and 33% of patients remain alive at 2 years and continue to be followed for survival.

In addition to the long-term survival data, vaccine treated patients had a median progression-free survival (PFS) of nearly 18 months, approximately two to three-times longer than patients treated with radiation and temozolomide alone1.  Importantly, 22% of patients were alive and without progression at 24 months and continue to be followed for survival.

The full text of the press release issued in connection with the announcement is being filed as Exhibit 99.1 to this current report on Form 8-K.
