September 27, 2012--Dendreon Corporation (NASDAQ:) today announced the first patient enrollment and initiation of treatment for the sipuleucel-T European Union (EU) open-label study. The open-label study is being conducted in European men with metastatic castrate-resistant prostate cancer (mCRPC) to describe product release parameters and report on safety in a European population. The study may enroll up to 45 patients in four sites across the EU. Dendreon has submitted a marketing authorization application (MAA) for sipuleucel-T which is currently under review by the European Medicines Agency (EMA). Sipuleucel-T is not approved for use outside the U.S. Sipuleucel-T is approved by the Food and Drug Administration (FDA) in the U.S. for the treatment of asymptomatic or minimally symptomatic metastatic castrate resistant prostate cancer. It is marketed under the name PROVENGE.
"We are extremely pleased with the progress of this new study and that the first patient has begun his treatment," said Thomas Powles MD, MRCP, Barts Cancer Institute, St. Bartholomew's Hospital, London. "We are also excited about the potential study outcomes and look forward to a successful program with the support of our committed clinical team and dedicated patients."
In addition to the current EU open-label study, the following data presentations are taking place at the ESMO 2012 Congress in Vienna, Austria, 28 September –2 October:
Approved for use in the U.S. only.
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 group.
