This week, we discuss two studies in genitourinary cancers presented at the ESMO Congress 2019. The CARD trial investigated treatment with cabazitaxel vs an androgen signaling–targeted inhibitor among patients with metastatic castration-resistant prostate cancer who had disease progression on docetaxel and the alternative androgen signaling–targeted inhibitor. The IMvigor130 trial focused on the efficacy and safety of atezolizumab as monotherapy or combined with platinum-based chemotherapy vs placebo plus platinum-based chemotherapy in previously untreated locally advanced or metastatic urothelial carcinoma.
