Abiraterone Acetate Significantly Improved Overall Survival for
Patients with Metastatic Advanced Prostate Cancer
Results observed in patients treated with abiraterone acetate plus whose disease progressed after docetaxel-based chemotherapy Based on the results of this Phase 3 study, Janssen plans to file marketing applications for abiraterone acetate with regulatory authorities worldwide MILAN, 11 October 2010 – Results from a pre-specified interim analysis of a randomized, placebo-controlled Phase 3 study, COU-AA-301, demonstrate that patients treated with the investigational oral agent abiraterone acetate plus low dose prednisone/prednisolone showed a significant improvement in overall survival compared to patients treated with prednisone/prednisolone plus placebo. This study included 1,195 patients with metastatic advanced prostate cancer (also referred to as castration-resistant prostate cancer, or CRPC) previously treated with one or two chemotherapy regimens, at least one of which contained docetaxel. The results of this randomized, placebo-controlled study were shared during a late-breaking presentation at the Presidential Symposium today at the 35th Annual European Society for Medical Oncology (ESMO) Congress. Treatment with abiraterone acetate resulted in a 35 percent reduction in the risk of death (HR=0.65; 95 percent CI: 0.54, 0.77; p<0.0001) and a 36 percent increase in median survival (14.8 months vs. 10.9 months) compared with placebo. Patients who received abiraterone acetate and low dose prednisone/prednisolone also showed significant improvements in secondary study endpoints when compared to the prednisone/prednisolone plus placebo group: time to PSA progression (TTPP) [median 10.2 months for abiraterone acetate vs. 6.6 months for placebo, HR=0.58 (95 percent CI: 0.46, 0.73); p<0.0001] and an increase in radiographic progression free survival (rPFS) [median 5.6 months for abiraterone acetate vs. 3.6 months for placebo, HR=0.67 (95 percent CI: 0.58, 0.78); p<0.0001]. Total PSA response, defined as greater than or equal to a 50 percent decrease from baseline, was achieved in 38 percent of patients treated with abiraterone acetate vs. 10 percent in the prednisone/prednisolone plus placebo group [p<0.0001]. Patients in the abiraterone acetate group experienced more mineralocorticoid-related adverse events than those in the prednisone/prednisolone plus placebo group. The most frequent adverse events were fluid retention (30.5 percent vs. 22.3 percent) and hypokalemia (17.1 percent vs. 8.4 percent). Grade 3/4 hypokalemia and hypertension were more frequent in the abiraterone acetate arm than in the placebo arm (3.8 percent vs. 0.8 percent and 1.3 percent vs. 0.3 percent, respectively). Liver function test abnormalities were observed in 10.4 percent of abiraterone acetate treated patients compared to 8.1 percent in the prednisone/prednisolone plus placebo group. Cardiac disorders were observed in 12.5 percent of abiraterone acetate patients vs. 9.4 percent of patients who received placebo. Mechanism-based adverse events were amenable to medical management and distinct from adverse events commonly associated with cytotoxic chemotherapy. “Abiraterone has the potential to meet a significant unmet need so this news will be incredibly important to prostate cancer patients and their families,” said Johann S. de Bono, MD, FRCP, MSc, PhD, The Institute of Cancer Research, The Royal Marsden NHS Foundation Trust, one of the lead COU-AA-301 investigators. “We are very pleased with the definitive results of this rigorous study, which show that abiraterone acetate may extend survival for men with metastatic advanced prostate cancer that progressed after treatment with docetaxel.” The Company plans to file marketing applications for abiraterone acetate with regulatory authorities in the United States and Europe by the end of the year. Applications in the rest of the world will follow, according to local regulatory requirements. If approved, abiraterone acetate will be commercialized and distributed by Centocor Ortho Biotech, Inc. in the United States and by Janssen Pharmaceutical Companies in all other countries around the world. “Globally, prostate cancer, the fifth most common cancer overall, is a significant public health problem,” said Howard I. Scher MD, Memorial Sloan-Kettering Cancer Center, another lead investigator. “These results are important because men with progressive metastatic, castration-resistant prostate cancer often have a poor prognosis and currently have few treatment options.” “The results of this abiraterone acetate Phase 3 study in patients with metastatic advanced prostate cancer bring us closer to achieving our goal of developing extraordinary preventive, diagnostic and therapeutic solutions based on our tumor microenvironment strategy,” said William N. Hait, MD, PhD, Global Therapeutic Head, Oncology, Ortho Biotech Oncology Research & Development. “We believe that abiraterone acetate is an important medical advance, and we look forward to further developing oncology therapeutic options that may impact patients’ lives.” Ortho Biotech Oncology Research & Development, a unit of Cougar Biotechnology, Inc., previously announced that the Independent Data Monitoring Committee recommended unblinding this Phase 3 study after a pre-specified interim analysis demonstrated a statistically significant improvement in median overall survival and an acceptable safety profile. The IDMC also recommended that patients in the prednisone/prednisolone plus placebo group be offered treatment with abiraterone acetate. Study Design
This randomized, double-blind placebo-controlled Phase 3 study was conducted
in 147 centers in 13 countries. Patients with metastatic advanced prostate
cancer previously treated with docetaxel (N=1,195) were randomly assigned 2:1
to receive abiraterone acetate (1000 mg once daily) plus prednisone/prednisolone (5 mg twice daily) (N = 797), or placebo plus prednisone/prednisolone (N = 398). The primary endpoint was overall survival.
About Abiraterone Acetate
Abiraterone acetate is a novel, targeted, investigational, oral androgen
biosynthesis inhibitor being developed for the treatment of metastatic advanced
prostate cancer that has progressed after developing resistance to conventional
hormonal therapies. This is also known as castration-resistant prostate cancer
(CRPC).
About Prostate Cancer
Prostate cancer occurs when cancer cells form in the tissues of the prostate.
The prostate is a gland located around the urethra (under the bladder) in men
that produces part of the seminal fluid.1 In some cases, cancer of the prostate
can grow slowly compared with other cancers. However, depending on factors
including characteristics specific to the patient and the tumor, prostate cancer can also grow very quickly2 and spread to other places such as the lymph nodes, bones or other parts of the body. Prostate cancer is considered to be advanced once it has spread beyond the prostate region.1 Globally, prostate cancer is the second most frequently diagnosed cancer in men and the fifth most common cancer overall.3 More than 900,000 new cases of prostate cancer were diagnosed in 2008 and more than 258,000 men died from the disease, a 16 percent increase from 2002.3,4 In the United States, an estimated 217,000 new cases of prostate cancer and 32,000 related deaths are expected to be reported in 2010.5 Prostate cancer represents almost one-third
of all new cancer diagnoses in men (excluding basal cell carcinoma) and is the
second-leading cause of cancer-related death in men.5
