Item 8.01 Other Events
On January 3, 2008, Antigenics Inc. announced that Acambis has released
results from a Phase 1 study of its ACAM-FLU-A(TM) vaccine, which contains
Antigenics' QS-21 Stimulon(R) adjuvant. Overall, the trial results demonstrated
that ACAM-FLU-A was well tolerated and capable of stimulating an immune
response. Although immune responses were observed in all groups that received
vaccine, the highest immune response was observed in the group vaccinated with
ACAM-FLU-A plus QS-21 adjuvant. In this group, 90 percent of subjects generated
virus-specific antibodies following immunization. Based on these results,
Acambis exercised its option for a commercial license to QS-21. Under the terms
of the agreement, Antigenics is entitled to receive future milestone payments
and product royalties in the event of successful development and
commercialization of ACAM-FLU-A.
The full text of the press release issued in connection with the
announcement is being furnished as Exhibit 99.1 to this current report on Form
8-K.
