Primary Results from SAUL, a Multinational Single-arm Safety Study of Atezolizumab Therapy for Locally Advanced or Metastatic Urothelial or Nonurothelial Carcinoma of the Urinary Tract (European Urology)

SAUL confirms the tolerability of atezolizumab in real-world patients with urinary tract carcinoma. Efficacy in the IMvigor211-like subgroup and the broader unselected population was consistent with previous anti-PD-L1/PD-1 pivotal trials, supporting the use of atezolizumab in these patients.
