? This Tecentriq combination is the first cancer immunotherapy regimen approved for breast cancer ? Triple-negative breast cancer is an aggressive disease, with high unmet medical need Basel, 11 March 2019 ? Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced that the US Food and Drug Administration (FDA) has granted accelerated approval to Tecentriq? (atezolizumab) plus chemotherapy (Abraxane? [paclitaxel protein-bound particles for injectable suspension (albumin-bound); nab-paclitaxel]) for the treatment of adults with unresectable locally advanced or metastatic triple-negative breast cancer (TNBC) in people whose tumours express PD-L1, as determined by an FDA-approved test. This indication is approved under accelerated approval based on progression-free survival (PFS). Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s). The FDA?s Accelerated Approval Programme allows conditional approval of a medicine that fills an unmet medical need for a serious or life-threatening disease or condition. ?The FDA approval of this Tecentriq combination is an important treatment advance for people with PD-L1- positive, metastatic triple-negative breast cancer, a disease with high unmet medical need,? said Sandra Horning, MD, Roche?s Chief Medical Officer and Head of Global Product Development. ?This Tecentriq combination is the first cancer immunotherapy regimen to be approved in breast cancer, representing a meaningful step forward in the understanding of this disease.? This accelerated approval is based on data from the Phase III IMpassion130 study, which demonstrated that Tecentriq plus nab-paclitaxel significantly reduced the risk of disease worsening or death (PFS) by 40% compared with nab-paclitaxel alone (median PFS=7.4 vs. 4.8 months; HR=0.60, 95% CI: 0.48-0.77, p<0.0001) in PD-L1-positive patients with unresectable locally advanced or metastatic TNBC who had not received prior chemotherapy for metastatic disease. Overall survival (OS) results were immature with 43% of events in all randomised patients (intent-to-treat; ITT), and further data will be shared with the FDA and presented at an upcoming medical meeting. Safety in the Tecentriq plus nab-paclitaxel arm appeared consistent with the known safety profiles of the individual medicines, and no new safety signals were identified with the combination. The most common Grade 3-4 side effects (=2%) with Tecentriq plus nab-paclitaxel were low white blood cells, tingling or numbness in the hands and feet, neutrophil count decreased, feeling tired, low red blood cells, low blood potassium level, pneumonia and increased blood level of a liver enzyme (AST). The most common side effects (=20 %) were hair loss, feeling tired, tingling or numbness in the hands and feet, nausea, diarrhoea, low red blood cells, constipation, cough, headache, low white blood cells, decreased appetite and vomiting. 2/4 About the IMpassion130 study The IMpassion130 study is a Phase III, multicentre, randomised, double-blind study evaluating the efficacy, safety and pharmacokinetics of Tecentriq plus nab-paclitaxel compared with placebo plus nab-paclitaxel in people with unresectable locally advanced or metastatic TNBC who have not received prior systemic therapy for metastatic breast cancer. The study enrolled 902 people who were randomised equally (1:1). The coprimary endpoints are PFS per investigator assessment (RECIST 1.1) in the ITT population and in the PDL1-positive population and OS in the ITT population. OS results were immature in the ITT population. Secondary endpoints include objective response rate and duration of response. About Triple-Negative breast cancer Breast cancer is the most common cancer among women with more than 2 million diagnosed worldwide each year.1TNBC represents 15% of all breast cancers and is more common in women under the age of 50, compared with other forms of breast cancer.2;3;4 It is defined by the lack of expression and/or amplification of the targetable receptors for oestrogen, progesterone and HER2 amplification.5 Patients with metastatic TNBC generally experience rapid progression and shorter OS compared to other subtypes of breast cancer.3 About Roche in breast cancer Roche has been advancing breast cancer research for more than 30 years with the goal of helping as many people with the disease as possible. Our medicines, along with companion diagnostic tests, have contributed to bringing breakthrough innovations in HER2-positive breast cancer. As our understanding of breast cancer biology rapidly improves, we are working to identify new biomarkers and approaches to treatment for all forms of early and advanced breast cancer, including triple-negative and hormone receptor-positive. Our targeted medicines Herceptin, Perjeta and Kadcyla are continuing to transform the treatment of early and advanced HER2-postive breast cancer and, through our Tecentriq and ipatasertib clinical programmes, we hope to bring new treatment combinations to people with breast cancer, ultimately improving outcomes. About Tecentriq Tecentriq is a monoclonal antibody designed to bind with a protein called PD-L1 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 has the potential to be used as a foundational combination partner with cancer immunotherapies, targeted medicines and various chemotherapies across a broad range of cancers. Tecentriq is already approved in the European Union, United States and more than 85 countries for people with previously treated metastatic non-small cell lung cancer (NSCLC) and for certain types of untreated or previously treated metastatic urothelial carcinoma (mUC). Tecentriq was also recently approved in the United States for the initial treatment of people with metastatic non-squamous NSCLC with no EGFR or ALK genomic tumour aberrations. 3/4 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 To learn more about the Roche approach to cancer immunotherapy please follow this link: http://www.roche.com/research_and_development/what_we_are_working_on/oncology/cancerimmunotherapy.htm About Roche Roche is a global pioneer in pharmaceuticals and diagnostics focused on advancing science to improve people?s lives.
