Agendia Announces Six Studies in Breast and Colon Cancer for Presentation at 2011 Annual Meeting of the American Society of Clinical Oncology (ASCO)

AMSTERAM and IRVINE, California, June 1, 2011 -

Agendia, a commercial-stage molecular cancer diagnostics
company, announces today that it will present results from four completed and
one ongoing study, at the Annual Meeting of the American Society of Clinical
Oncology (ASCO). Agendia will publish the results of an additional study in
conjunction with the event. The meeting will be held from 3-7 June, 2011 at
McCormick Place in Chicago, IL.

Currently on the market in US and Europe, Agendia's Symphony(TM) suite of
molecular diagnostic breast cancer tests enables physicians to determine
whether a given breast cancer patient is likely to benefit from hormonal
therapy, chemotherapy and targeted therapies, thereby providing benefits over
existing treatment approaches for patients, physicians and payors.

Agendia's lead product, Mammaprint(R), is currently the only molecular
diagnostic breast cancer recurrence test available on the market to have
received FDA clearance. Agendia's product development pipeline includes a
further extension of its breast cancer tests as well as similar molecular
diagnostic products for colon cancer.

All of the abstracts listed below can currently be found
online at www.ASCO.org. Presentation details are as follows (all times
are in Central Time).
