Novel approaches are needed for patients with metastatic urothelial cancer (UC). This trial assessed the efficacy and toxicity of bevacizumab in combination with cisplatin and gemcitabine (CGB) as first-line treatment for patients with metastatic UC.


Chemotherapy-naive patients with metastatic or unresectable UC received cisplatin 70 mg/m(2) on day 1, gemcitabine 1,000 to 1,250 mg/m(2) on days 1 and 8, and bevacizumab 15 mg/kg on day 1, every 21 days.


Forty-three patients with performance status of 0 (n = 26) or 1 (n = 17) and median age of 66 years were evaluable for toxicity and response. Grade 3 to 4 hematologic toxicity included neutropenia (35%), thrombocytopenia (12%), anemia (12%), and neutropenic fever (2%). Grade 3 to 5 nonhematologic toxicity included deep vein thrombosis/pulmonary embolism (21%), hemorrhage (7%), cardiac (7%), hypertension (5%), and proteinuria (2%). Three treatment-related deaths (CNS hemorrhage, sudden cardiac death, and aortic dissection) were observed. Best response by Response Evaluation Criteria in Solid Tumors was complete response in eight patients (19%) and partial response in 23 patients (53%), for an overall response rate of 72%. Stable disease lasting ≥ 12 weeks occurred in four patients (9%), and progressive disease occurred in six patients (14%). With a median follow-up of 27.2 months (range, 3.5 to 40.9 months), median progression-free survival (PFS) was 8.2 months (95% CI, 6.8 to 10.3 months) with a median overall survival (OS) time of 19.1 months (95% CI, 12.4 to 22.7 months). The study-defined goal of 50% improvement in PFS was not met.


CGB demonstrates promising OS and antiangiogenic treatment-related toxicities in the phase II setting of metastatic UC. The full risk/benefit profile of CGB in patients with metastatic UC will be determined by an ongoing phase III intergroup trial.
