A Phase 2 Study of Atezolizumab (an Engineered Anti-PDL1 Antibody) as Monotherapy or in Combination With Avastin (Bevacizumab) Compared to Sunitinib in Patients With Untreated Advanced Renal Cell Carcinoma [IMmotion150]


NCT ID: NCT01984242
Sponsor Protocol Number: WO29074

About this study

This multicenter, randomized, open-label study will evaluate the efficacy and safety of atezolizumab as monotherapy or in combination with Avastin (bevacizumab) versus sunitinib in patients with previously untreated locally advanced or metastatic renal cell carcinoma. Patients in Arm A will receive atezolizumab 1200 mg IV every 3 weeks (6-week cycles) plus Avastin 15 mg/kg IV until disease progression. Patients in Arm B will receive atezolizumab alone (until disease progression), and patients in Arm C will receive sunitinib 50 mg orally daily for 4 weeks followed by 2 weeks rest until disease progression. Following disease progression, patients in Arms B and C will be given the option to receive combination treatment with atezolizumab and Avastin. Patients enrolled into arm B (atezolizumab alone) in Europe (including France, Italy, the United Kingdom, Romania, Spain, Germany, the Czech Republic and Poland) are not eligible to cross over into arm A to receive combination treatment with atezolizumab and bevacizumab following disease progression, per local regulatory requirement.
