Xtandi Better, Cheaper than Zytiga for Treatment of mCRPC, Study Suggests
Treating chemotherapy-naive metastatic castration-resistant prostate cancer (mCRPC) patients with Xtandi (enzalutamide) leads to better survival outcomes and lower healthcare costs than Zytiga (abiraterone acetate), a study suggests. The findings were presented at the American Urological Association's 2019 Annual Meeting, May 3-6, in Chicago, in the study, "Survival Rates and Economic Outcomes in Chemotherapy-naive Metastatic Castrate Resistant Prostate Cancer Patients Treated with Abiraterone Acetate or Enzalutamide." While therapies that lower male sex hormones — required for prostate cancer to survive and grow — are a mainstay of therapy for advanced prostate cancer, most patients will acquire resistance to such approaches. This often happens because the receptor for these hormones, called the androgen receptor, becomes constantly active, even in the absence of androgens. Therapies that inhibit the androgen receptor — such as Pfizer and Astellas' Xtandi and Janssen's Zytiga — have largely improved the overall survival of prostate cancer patients, and are now approved for mCRPC patients in the U.S. and Europe. However, which treatment brings the most benefits or the lowest healthcare
