F. Hoffmann-La Roche Ltd: Roche to present updated data confirming Tecentriq in combination with Avastin substantially improves overall survival in people with the most common form of liver cancer 19.2 6.9 18.1 Tecentriq + Avastin (n=133) 24.0 (0.35-0.80) Median follow-up: 15.6 months. CR, complete response; DOR, duration of response; HR, hazard ratio; NE, not estimable; ORR, objective response rate; OS, overall survival; PFS, progression free response; PR, partial response; SD, stable disease. See below for OS data from the primary analysis. About the IMbrave150 study IMbrave150 is a global Phase III, multicentre, open-label study of 501 people with unresectable HCC who had not received prior systemic therapy. People were randomised 2:1 to receive the combination of Tecentriq and Avastin or sorafenib. Tecentriq was administered intravenously (IV), 1200 mg on day 1 of each 21-day cycle, and Avastin was administered IV, 15 mg/kg on day 1 of each 21-day cycle. Sorafenib was administered by mouth, 400 mg twice per day, on days 1-21 of each 21-day cycle. People received the combination or the control arm treatment until disease progression or unacceptable toxicity. The two primary endpoints were OS and independent review facility (IRF)-assessed PFS per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1). Additional study endpoints included IRF-assessed overall response rate (ORR) per RECIST v1.1 and HCC mRECIST.
