– New, long-term preliminary data from Phase II STAND trial to be presented at 2015 Genitourinary Cancers Symposium (ASCO GU)
– Successful efforts to nearly double African American enrollment in PROCEED prostate cancer registry also highlighted
LAVAL, Canada I February 25, 2015 I Valeant Pharmaceuticals International, Inc. (NYSE: VRX) (TSX: VRX) today announced the presentation of new long-term, preliminary results from the Phase II STAND trial demonstrating a robust immune response with PROVENGE® (sipuleucel-T) that continues two years after completing treatment in men with biochemically-recurrent prostate cancer (BRPC). The findings, along with valuable data from the ongoing Phase IV registry, PROCEED, related to increasing enrollment of African Americans in prostate cancer trials, are being presented at the 2015 Genitourinary Cancers Symposium (ASCO GU) February 26-28 in Orlando, Florida.
The STAND study is a randomized, Phase II trial that consisted of two patient study groups. One group completed PROVENGE two weeks before initiation of androgen deprivation therapy (ADT) and the second received PROVENGE three months after the start of ADT. PROVENGE is not indicated for use in patients with BRPC. Preliminary results from STAND indicate that immune responses were observed in both study arms and suggest there may be a greater cellular immune response in patients who received PROVENGE prior to ADT compared with those who received PROVENGE following three months of ADT. Humoral immune responses were observed and similar between both treatment arms.
“It is very encouraging to observe that PROVENGE provides an immune response in men with biochemical-recurrent prostate cancer long after the course of androgen deprivation therapy has ended,” said Neal Shore, M.D., medical director at the Carolina Urologic Research Center. “This study may also provide guidance on the optimal sequencing of immunotherapy and ADT in biochemical-recurrent prostate cancer.”
PROVENGE, the first personalized immunotherapy, stimulates a patient’s own immune system to fight cancer. It is approved in the U.S. and the European Union as a treatment for asymptomatic or minimally symptomatic metastatic castrate-resistant prostate cancer.
“These are very encouraging preliminary data and the longest duration of immune responses observed following PROVENGE completion in men with this particular type of prostate cancer,” said Andrew S. Sandler, M.D., chief medical officer at Dendreon. “Dendreon and Valeant remains committed to exploring the use of PROVENGE in different prostate cancer treatment settings to provide important clinical information to practicing oncologists.”
In 2012, an exploratory analysis of African American patients from the PROVENGE Phase III trials suggested a positive treatment effect in this population. Building on this observation, another abstract being presented at ASCO GU highlights successful efforts that nearly doubled enrollment of African American men in the ongoing PROCEED registry. Through tactics such as utilizing research sites in racially and ethnically diverse communities, conducting focus groups with African Americans for insight on recruitment materials and study plans, and educating research staff on enrollment goals, enrollment in this population was 11.7 percent, a rate comparable to the U.S. African American population, versus 5.8 percent in the PROVENGE Phase III registration trials. Overall, African American men are underrepresented in randomized clinical trials for prostate cancer, yet they have the highest incidence rate for prostate cancer in the United States and are more than twice as likely as white men to die of the disease.i
Important Safety Information for PROVENGE
PROVENGE® (sipuleucel-T) is an autologous cellular immunotherapy indicated for the treatment of asymptomatic or minimally symptomatic metastatic castrate-resistant (hormone-refractory) prostate cancer.

Tell your doctor right away if you:
Have breathing problems, chest pains, racing heart or irregular heartbeats, high or low blood pressure, dizziness, fainting, nausea, or vomiting after getting PROVENGE. Any of these may be signs of heart or lung problems.
Develop numbness or weakness on one side of the body, decreased vision in one eye or difficulty speaking. Any of these may be signs of a stroke.
Develop symptoms of thrombosis which may include pain and/or swelling of an arm or leg with warmth over the affected area, discoloration of an arm or leg, unexplained shortness of breath or chest pain that worsens on deep breathing.
Get a fever over 100°F, or redness or pain at the infusion or collection sites. Any of these may be signs of infection.
