Dendreon Reports First Quarter 2008 Financi...(ltof our recent financing we expect to h...)

Recent Events:

-- The FDA agreed to amend the IMPACT (IMmunotherapy for Prostate

AdenoCarcinoma Treatment) SPA, accelerating the expected timeline for

final results from the study by approximately one year while

maintaining comparable power to the previous SPA. In addition, the FDA

reconfirmed that either a positive interim or final analysis of

survival would support licensure and enable Dendreon to amend the

Company's biologics license application for PROVENGE.

-- Completed a registered direct stock offering resulting in the receipt

of net proceeds of approximately $46 million. With this cash infusion,

the Company has adequate resources to complete the IMPACT trial and

finance operations through the final analysis of that trial.

-- Presented clinical data from a Phase 1 trial of Neuvenge(TM)

(lapuleucel-T) demonstrating that the Active Cellular Immunotherapy,

which is based on the same Antigen Delivery Cassette(TM) technology as

PROVENGE, may not only have potential clinical benefit in breast

cancer, but also in ovarian and colorectal cancers. These data were

presented in April at the American Association for Cancer Research

annual meeting.

-- In lieu of Dendreon's regularly scheduled quarterly conference call,

the Company will present at several upcoming investor conferences that

will be webcast, two of which are later this month and include:

- Bank of America Health Care Conference on May 13, 2008

- The Rodman & Renshaw 5th Annual Global Healthcare Conference on

May 19, 2008
