PROVENGE Indication and Important Safety Information

PROVENGE^® (sipuleucel-T) is an autologous cellular immunotherapy indicated
for the treatment of asymptomatic or minimally symptomatic metastatic castrate
resistant (hormone refractory) prostate cancer.

PROVENGE is intended solely for autologous use and is not routinely tested for
transmissible infectious diseases.

The safety evaluation of PROVENGE was based on 601 prostate cancer patients in
four randomized clinical trials who underwent at least one leukapheresis. The
most common adverse events (incidence greater-than or equal to 15%) are
chills, fatigue, fever, back pain, nausea, joint ache, and headache. Serious
adverse events reported in the PROVENGE group include acute infusion reactions
(occurring within 1 day of infusion) and cerebrovascular events. In controlled
clinical trials, severe (Grade 3) acute infusion reactions were reported in
3.5% of patients in the PROVENGE group. Reactions included chills, fever,
fatigue, asthenia, dyspnea, hypoxia, bronchospasm, dizziness, headache,
hypertension, muscle ache, nausea, and vomiting. No Grade 4 or 5 acute
infusion reactions were reported in patients in the PROVENGE group.

To fulfill a post marketing requirement and as a part of the company's ongoing
commitment to patients, Dendreon will conduct a registry of approximately 1500
patients to further evaluate a small potential safety signal of
cerebrovascular events. In four randomized clinical trials of PROVENGE in
prostate cancer patients, cerebrovascular events were observed in 3.5% of
patients in the PROVENGE group compared with 2.6% of patients in the control
