Results:
113 patients (78% male; median age 66 y; 72% ECOG PS 1; Bellmunt score 0 [12%],1 [54%], 2 [27%],3 [6%]; 62% with visceral metastases) received a median of 3 prior therapies. Central review confirmed an ORR of 27% (31/113; 95% CI 19–37) with 6 complete responses, 25 partial responses and 25% (95% CI 11.5–43.4) ORR in patients with liver metastases. Median DOR was 5.9 mo (95% CI 4.7–8.6) and clinical benefit rate was 37% (42/113). Median PFS and OS were 5.4 mo (95 %CI 3.5- 6.9) and 10.5 mo (95 %CI 8.2–12.3), respectively. Key grade ≥3 treatment-related adverse events were neutropenia (35%), anemia (14%), febrile neutropenia (10%), and diarrhea (10%). There was no treatment-related grade >2 ocular toxicity, neuropathy or interstitial lung disease. There was 1 treatment-related death (neutropenic sepsis)
