- First Phase III cancer immunotherapy study to show an improvement in overall survival and progression-free survival for the treatment of the most common form of liver cancer
- Data will be submitted to health authorities globally, including the U.S. Food and Drug Administration, the European Medicines Agency and the China National Medical Products Administration
Roche today announced that the Phase III IMbrave150 study, evaluating Tecentriq (atezolizumab) in combination with Avastin (bevacizumab) as a treatment for people with unresectable hepatocellular carcinoma (HCC) who have not received prior systemic therapy, met both of its co-primary endpoints demonstrating statistically significant and clinically meaningful improvements in overall survival (OS) and progression-free survival (PFS) compared with standard-of-care sorafenib.
Safety for the combination of Tecentriq and Avastin was consistent with the known safety profiles of the individual medicines, with no new safety signals identified. Data from the IMbrave150 study will be presented at an upcoming medical meeting.
“We are very pleased with the results of our study testing the combination of Tecentriq and Avastin, which marks the first treatment in more than a decade to improve overall survival in people with unresectable hepatocellular carcinoma who have not received prior systemic therapy,” said Levi Garraway, M.D. Ph.D, Chief Medical Officer and Head of Global Product Development. “HCC is a major cause of death globally and particularly in Asia, making this study an important step in our mission of addressing unmet medical needs for patients around the world. We will submit these data to global health authorities as soon as possible. Our hope is to bring a new treatment to people with this aggressive disease who currently have limited options.”
In July 2018, the U.S. Food and Drug Administration (FDA) granted Breakthrough Therapy Designation (BTD) for Tecentriq in combination with Avastin in HCC based on data from an ongoing Phase Ib trial.
Roche has an extensive development programme for Tecentriq, including multiple ongoing and planned Phase III studies, across 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 HCC who have not received prior systemic therapy. People were randomised 2:1 to receive the combination of Tecentriq and Avastin or sorafenib. Tecentriq was administered intravenously, 1200 mg on day 1 of each 21-day cycle, and Avastin was administered intravenously, 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 unacceptable toxicity or loss of clinical benefit as determined by the investigator. Co-primary endpoints were OS and PFS by independent-review facility (IRF) per RECIST v1.1. Secondary efficacy endpoints included overall response rate (ORR), time to progression (TTP) and duration of response (DOR), as measured by RECIST v1.1 (investigator-assessed [INV] and IRF) and HCC mRECIST (IRF), as well as patient-reported outcomes (PROs), safety and pharmacokinetics.
About hepatocellular carcinoma
HCC is an aggressive cancer with limited treatment options and is a major cause of cancer deaths worldwide.1 The disease affects over 750,000 people every year,1,2 with the majority of cases in Asia and almost half of all cases in China.2,3 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.4,5 HCC develops predominantly in people with cirrhosis due to chronic hepatitis (B or C) or alcohol consumption, and typically presents at an advanced stage.1 The prognosis for unresectable HCC remains poor, with few systemic therapeutic options and a 1-year survival rate of less than 50% following diagnosis.6
About the Tecentriq and Avastin combination
There is a strong scientific rationale to support the use of Tecentriq plus Avastin in combination. The Tecentriq and Avastin regimen may enhance the potential of the immune system to combat a broad range of cancers. Avastin, in addition to its established anti-angiogenic effects, may further enhance Tecentriq’s ability to restore anti-cancer immunity, by inhibiting vascular endothelial growth factor (VEGF)-related immunosuppression, promoting T-cell tumour infiltration and enabling priming and activation of T-cell responses against tumour antigens.
Tecentriq is a monoclonal antibody designed to bind with a protein called PD-L1, which is expressed on tumour cells and tumour-infiltrating immune cells, blocking its interactions with both PD-1 and B7.1 receptors. By inhibiting PD-L1, Tecentriq may enable the activation of T cells. Tecentriq is a cancer immunotherapy that has the potential to be used as a foundational combination partner with other immunotherapies, targeted medicines and various chemotherapies across a broad range of cancers. The development of Tecentriq and its clinical programme is based on our greater understanding of how the immune system interacts with tumours and how harnessing a person’s immune system combats cancer more effectively.
Tecentriq is approved in the US, EU and countries around the world, either alone or in combination with targeted therapies and/or chemotherapies in various forms of non-small cell and small cell lung cancer, certain types of metastatic urothelial cancer, and in PD-L1-positive metastatic triple-negative breast cancer.
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 tumour to develop and maintain blood vessels, a process known as angiogenesis. Avastin is designed to interfere with the tumour blood supply by directly binding to the VEGF protein to prevent interactions with receptors on blood vessel cells. The tumour blood supply is thought to be critical to a tumour’s ability to grow and spread in the body (metastasise).
About Roche in cancer immunotherapy
For more than 50 years, Roche has been developing medicines with the goal to redefine treatment in oncology. Today, we’re investing more than ever in our effort to bring innovative treatment options that help a person’s own immune system fight cancer.
By applying our seminal research in immune tumour profiling within the framework of the Roche-devised cancer immunity cycle, we are accelerating and expanding the transformative benefits with Tecentriq to a greater number of people living with cancer. Our cancer immunotherapy development programme takes a comprehensive approach in pursuing the goal of restoring cancer immunity to improve outcomes for patients.
