Basel, 22 March 2021 ? Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced that the Phase III IMpower010 study evaluating Tecentriq? (atezolizumab), compared with best supportive care (BSC), met its primary endpoint of disease-free survival (DFS) at the interim analysis. Tecentriq showed a statistically significant improvement in DFS as adjuvant therapy following surgery and chemotherapy in all randomised Stage II-IIIA populations with non-small cell lung cancer (NSCLC). The magnitude of DFS benefit was particularly pronounced in the PD-L1-positive population. Follow-up will continue with planned analyses of DFS in the overall intent-to-treat (ITT) population, which at the time of analysis did not cross the threshold, and overall survival (OS) data, which were immature at the time of interim analysis. Safety for Tecentriq was consistent with its known safety profile and no new safety signals were identified. Results from the IMpower010 study will be presented at an upcoming medical meeting and submitted to health authorities globally, including the U.S. Food and Drug Administration and the European Medicines Agency. ?With these landmark results, Tecentriq has become the first cancer immunotherapy to help many people with resectable early lung cancer live longer without their cancer returning," said Levi Garraway, M.D., Ph.D., Roche?s Chief Medical Officer and Head of Global Product Development. ?We?re excited by the clinical benefit adjuvant Tecentriq may bring to lung cancer patients, particularly in the PD-L1-positive population. We will submit these data to regulatory authorities as soon as possible.? Tecentriq has previously shown clinically meaningful benefit in various types of lung cancer, with five currently approved indications in markets around the world. It was the first approved cancer immunotherapy for front-line treatment of adults with extensive-stage small cell lung cancer (SCLC) in combination with carboplatin and etoposide (chemotherapy). Tecentriq also has four approved indications in NSCLC as either a single agent or in combination with targeted therapies and/or chemotherapies. Furthermore, Roche has an extensive development programme 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. About the IMpower010 study IMpower010 is a Phase III, global, multicentre, open-label, randomised study evaluating the efficacy and safety of Tecentriq compared with BSC, in participants with Stage IB-IIIA NSCLC (UICC 7th edition), following surgical resection and up to 4 cycles of adjuvant cisplatin-based chemotherapy. The study randomised 1,005 people with a ratio of 1:1 to receive either at most 16 cycles of Tecentriq or BSC. The primary endpoint is investigator-determined DFS in the PD-L1-positive Stage II-IIIA, all randomised Stage II-IIIA and ITT Stage IB-IIIA populations. Key secondary endpoints include OS in the overall study population, ITT Stage IB-IIIA NSCLC. About NSCLC Lung cancer is the one of the leading causes of cancer death globally.¹?Each year 1.8 million people die as a result of the disease; this translates into more than 4,900 deaths worldwide every day.¹?Lung cancer can be broadly divided into two major types: NSCLC and small cell lung cancer. NSCLC is the most prevalent type, accounting for around 85% of all cases.²?NSCLC comprises non-squamous and squamous-cell lung cancer, the squamous form of which is characterised by flat cells covering the airway surface when viewed under a microscope.² About Tecentriq Tecentriq is a monoclonal antibody designed to bind with a protein called Programmed Death Ligand-1 (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 NSCLC, SCLC, certain types of metastatic urothelial cancer, in PD-L1-positive metastatic triple-negative breast cancer and for hepatocellular carcinoma. In the US, Tecentriq is also approved in combination with Cotellic? (cobimetinib) and Zelboraf? (vemurafenib) for the treatment of people with BRAF V600 mutation-positive advanced melanoma. About Roche in cancer immunotherapy Roche?s rigorous pursuit of groundbreaking science has contributed to major therapeutic and diagnostic advances in oncology over the last 50 years, and today, realising the full potential of cancer immunotherapy is a major area of focus. With over 20 molecules in development, Roche is investigating the potential benefits of immunotherapy alone, and in combination with chemotherapy, targeted therapies or other immunotherapies with the goal of providing each person with a treatment tailored to harness their own unique immune system to attack their cancer. Our scientific expertise, coupled with innovative pipeline and extensive partnerships, gives us the confidence to continue pursuing the vision of finding a cure for cancer by ensuring the right treatment for the right patient at the right time. In addition to Roche?s approved PD-L1 checkpoint inhibitor, Tecentriq? (atezolizumab), Roche?s broad cancer immunotherapy pipeline includes other checkpoint inhibitors, such as tiragolumab, a novel cancer immunotherapy designed to bind to TIGIT, individualised neoantigen therapies and T-cell bispecific antibodies.
