In the first-ever positive Phase III trial in the adjuvant hepatocellular carcinoma (HCC) setting, Tecentriq plus Avastin reduced the risk of disease recurrence by 28%
Up to 80% of people with this type of HCC experience disease recurrence, at which point they are faced with poorer prognosis and shorter survival
These data will be presented at the American Association for Cancer Research (AACR) Annual Meeting 2023 and included in the official press program
South San Francisco, CA -- April 16, 2023 --
Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), announced today new data from the Phase III IMbrave050 study that show Tecentriq® (atezolizumab) plus Avastin® (bevacizumab) demonstrated a statistically significant improvement in recurrence-free survival (RFS) in people with hepatocellular carcinoma (HCC) at high risk of disease recurrence following liver resection or ablation with curative intent.
“Four out of five people with HCC who receive surgery with curative intent may still see their cancer return. Thus, an urgent need exists for adjuvant treatments to prevent early recurrence and improve survival rates,” said Levi Garraway, M.D., Ph.D., chief medical officer and head of Global Product Development. “With Tecentriq plus Avastin already a standard of care in unresectable HCC, we are pleased with the potential of these results and look forward to seeing more mature data.”
The Tecentriq investigational combination reduced the risk of cancer returning by 28%, compared with active surveillance, at a median follow-up of 17.4 months (independent review facility [IRF]-RFS hazard ratio [HR]=0.72, 95% CI: 0.56-0.93; P=0.0120). The IRF-RFS findings were generally consistent across clinical subgroups. Overall survival (OS), a key secondary endpoint, was immature (7% event-rate) at the time of data analysis. The safety data for Tecentriq plus Avastin were consistent with the well-established safety profile of each therapeutic treatment and with the underlying disease.
The late-breaking data will be presented at the AACR Annual Meeting 2023 and have been included as part of the official press program. Discussions with health authorities are ongoing and follow-up will continue for the final RFS data and more mature OS data at the next planned analysis.
The IMbrave050 study is part of Genentech’s overall commitment to drive fundamental treatment change and improve outcomes for people living with liver cancer. Tecentriq plus Avastin was the first treatment in over a decade to significantly improve OS over the existing standard of care, based on data from the IMbrave150 study. The Tecentriq combination quickly became a standard of care in unresectable HCC and is clearly defined as a preferred front-line treatment in multiple international clinical guidelines.
Genentech has an extensive development program for Tecentriq, including multiple ongoing and planned Phase III studies across different lung, genitourinary, skin, breast, gastrointestinal, gynecological, and head and neck cancers. This includes studies evaluating Tecentriq both alone and in combination with other medicines, as well as studies in metastatic, adjuvant and neoadjuvant settings across various tumor types. In addition, Genentech has developed a subcutaneous formulation of Tecentriq, which is currently under review by health authorities globally.
About the IMbrave050 study
IMbrave050 is a Phase III global, multicenter, open-label, randomized study evaluating the efficacy and safety of adjuvant Tecentriq plus Avastin, compared with active surveillance, in people with HCC at high risk of recurrence (determined by the size and number of cancerous lesions and the histopathology results, if available) after surgical resection or ablation with curative intent.
The study randomized 668 people with a ratio of 1:1 to receive either Tecentriq (1,200 mg every three weeks) plus Avastin (15 mg/kg every three weeks) for a period of 12 months or 17 cycles, or no intervention with active surveillance. The primary endpoint is independent review facility-assessed RFS. Key secondary endpoints include OS, RFS as determined by the investigator and RFS in patients with PD-L1-positive disease.
About hepatocellular carcinoma
Liver cancer is the third leading cause of cancer death and one of the few cancers where mortality is rising. It is estimated that nearly 42,000 Americans were diagnosed with liver cancer in 2022. Nine out of ten cases of HCC are caused by chronic liver disease, which includes chronic hepatitis B and C infection, non-alcoholic fatty liver disease (NAFLD), non-alcoholic steatohepatitis (NASH), alcohol-related liver disease (ALD) and cirrhosis resulting from these conditions.
If diagnosed in the early stage, surgery may be prescribed to remove the primary tumor, however an estimated 70-80% of people with early-stage HCC experience disease recurrence following surgery. Early recurrence is associated with poorer prognosis and shorter survival. Tumor size, number of tumors, and portal vein invasion are associated with an increased risk of recurrence.
About Tecentriq® (atezolizumab)
Tecentriq is a monoclonal antibody designed to bind with a protein called PD-L1. Tecentriq is designed to bind to PD-L1 expressed on tumor cells and tumor-infiltrating immune cells, blocking its interactions with both PD-1 and B7.1 receptors. By inhibiting PD-L1, Tecentriq may enable the re-activation of T cells. Tecentriq may also affect normal cells.
About Avastin® (bevacizumab)
Avastin is a prescription-only medicine that is a solution for intravenous infusion. It is a biologic antibody designed to specifically bind to a protein called VEGF that plays an important role throughout the lifecycle of the tumor to develop and maintain blood vessels, a process known as angiogenesis. Avastin is designed to interfere with the tumor blood supply by directly binding to the VEGF protein to prevent interactions with receptors on blood vessel cells. The tumor blood supply is thought to be critical to a tumor’s ability to grow and spread in the body (metastasize).

Important Safety Information
What is the most important information about Tecentriq?
Tecentriq can cause the immune system to attack normal organs and tissues in any area of the body and can affect the way they work. These problems can sometimes become severe or life threatening and can lead to death. Patients can have more than one of these problems at the same time. These problems may happen anytime during their treatment or even after their treatment has ended.
Patients should call or see their healthcare provider right away if they develop any new or worse signs or symptoms, including:

Complications, including graft-versus-host disease (GVHD), in people who have received a bone marrow (stem cell) transplant that uses donor stem cells (allogeneic). These complications can be serious and can lead to death. These complications may happen if patients undergo transplantation either before or after being treated with Tecentriq. A healthcare provider will monitor for these complications.
Getting medical treatment right away may help keep these problems from becoming more serious. A healthcare provider will check patients for these problems during their treatment with Tecentriq. A healthcare provider may treat patients with corticosteroid or hormone replacement medicines. A healthcare provider may also need to delay or completely stop treatment with Tecentriq if patients have severe side effects.
