• IMvigor130 is the first positive Phase III study of a cancer immunotherapy combination in previously untreated advanced bladder cancer
• Data will be shared with health authorities globally, including the U.S. Food and Drug Administration (FDA) and European Medicines Agency (EMA)

Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced that the Phase III IMvigor130 study met its co-primary endpoint of investigator-assessed progression-free survival (PFS). The combination of Tecentriq^??(atezolizumab) plus platinum-based chemotherapy showed a statistically significant reduction in the risk of disease worsening or death (PFS) in people with previously untreated locally advanced or metastatic urothelial carcinoma (mUC) compared with chemotherapy alone. Encouraging overall survival (OS) results were observed at this interim analysis; however, these data are not yet mature and follow-up will continue until the next planned analysis. Safety in the Tecentriq plus chemotherapy arm appeared consistent with the known safety profiles of the individual medicines and no new safety signals were identified with the combination. Results will be presented at an upcoming medical meeting and shared with health authorities globally, including the U.S. Food and Drug Administration (FDA) and European Medicines Agency (EMA). ?IMvigor130 is the first positive Phase III study of a cancer immunotherapy combination in previously untreated advanced bladder cancer, an aggressive disease with high unmet need,? said Sandra Horning, M.D., Chief Medical Officer and Head of Global Product Development. ?These results support our broad clinical development programme for Tecentriq in bladder cancer, as well as our approach of combining immunotherapy with chemotherapy or other medicines to improve patient outcomes, and we look forward to discussing them with health authorities.? Tecentriq was the first cancer immunotherapy approved in bladder cancer. Currently, there are four ongoing Phase III studies evaluating Tecentriq alone and in combination with other medicines in early and advanced bladder cancer. 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 IMvigor130 study

IMvigor130 is a multicentre, partially blinded, randomised Phase III study, evaluating the efficacy and safety of Tecentriq in combination with chemotherapy or alone versus chemotherapy alone for people with mUC who have not received prior systemic therapy for metastatic disease. It enrolled 1213 people who were randomised to receive:

• Tecentriq plus platinum-based chemotherapy (gemcitabine with either cisplatin or carboplatin), or
• Tecentriq, or
• Platinum-based chemotherapy (gemcitabine with either cisplatin or carboplatin) plus placebo (control arm).

In the Tecentriq combination arm, co-primary endpoints are OS and PFS as assessed by investigator using Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1).

About bladder cancer

In 2018, there were over half a million new cases of bladder cancer diagnosed globally, with around 200,000 deaths from the disease.¹?Urothelial carcinoma, which develops in the cells of the bladder lining, is the most common type of bladder cancer, accounting for about 90% of all cases.²?In total, 30% of cases are considered advanced based on muscle-invasive or metastatic disease.³

About Tecentriq

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/or 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 mUC, and in PD-L1-positive triple-negative breast cancer.
