FDA approves Roche’s Tecentriq in combination with Avastin for people with the most common form of liver cancer - Seite 2

The approval was based on results from the Phase III IMbrave150 study, which demonstrated that Tecentriq in combination with Avastin reduced the risk of death (overall survival; OS) by 42% (hazard ratio [HR]=0.58; 95% CI: 0.42-0.79; p=0.0006) and reduced the risk of disease worsening or death (progression-free survival; PFS) by 41% (HR=0.59; 95% CI: 0.47-0.76; p<0.0001), compared with sorafenib. IMbrave150 is the first Phase III cancer immunotherapy study to show an improvement in OS and PFS in people with unresectable or metastatic HCC compared with sorafenib. Serious adverse reactions (Grade 3-4) occurred in 38% of people in the Tecentriq and Avastin arm. The most frequent serious adverse reactions (≥2%) were bleeding in the gastrointestinal tract, infections and fever. These results were published in the New England Journal of Medicine on 14 May 2020.

Roche has an extensive development programme for Tecentriq, including multiple ongoing and planned Phase III studies, across several types of lung, genitourinary, skin, breast, gastrointestinal, gynaecological and head and neck cancers. This includes studies evaluating Tecentriq both alone and in combination with other medicines.

About the IMbrave150 study
IMbrave150 is a global Phase III, multicentre, open-label study of 501 people with unresectable or metastatic 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 were IRF-assessed overall response rate (ORR) per RECIST and mRECIST.

About hepatocellular carcinoma
HCC is an aggressive cancer with limited treatment options and is a major cause of cancer deaths worldwide.² Every year, more than 750,000 people worldwide are diagnosed with HCC,^2,3 with the majority of cases in Asia and almost half of all cases in China.^3,4 In the US, the number of liver cancer cases have more than tripled since 1980 and HCC represents the fastest-rising cause of cancer-related death, while in Europe, liver cancer is also on the rise.^5-7 HCC develops predominantly in people with cirrhosis due to chronic hepatitis (B or C) or alcohol consumption, and typically presents at an advanced stage.² The prognosis for unresectable HCC remains poor, with few systemic therapeutic options and a 1-year survival rate of less than 50% following diagnosis.⁸
