Basel, 25 June 2021 - Roche (SIX: RO, ROG; OTCQX: RHHBY) announced today that the U.S. Food and Drug Administration (FDA) has issued an Emergency Use Authorization (EUA) for intravenous Actemra/RoActemra? (tocilizumab) for the treatment of COVID-19 in hospitalised adults and paediatric patients (two years of age and older) who are receiving systemic corticosteroids and require supplemental oxygen, non-invasive or invasive mechanical ventilation, or extracorporeal membrane oxygenation (ECMO). The EUA is based on results from four randomised, controlled studies that evaluated Actemra/RoActemra for the treatment of COVID-19 in more than 5,500 hospitalised patients. The results of these studies suggest that Actemra/RoActemra may improve outcomes in patients receiving corticosteroids and requiring supplemental oxygen or breathing support. ?Even with the availability of vaccines and declines in deaths from COVID-19 in various parts of the world, we continue to see new hospitalisations from severe forms of the disease,? said Levi Garraway, M.D., Ph.D., Roche?s Chief Medical Officer and Head of Global Product Development. ?We are pleased that Actemra/RoActemra is now authorised as an option that may help improve outcomes for adults and children hospitalised with COVID-19 in the United States.? The four randomised, controlled studies included in the EUA submission investigated the safety and efficacy of Actemra/RoActemra in more than 5,500 hospitalised patients with COVID-19. The RECOVERY Actemra/RoActemra study was led by researchers in the United Kingdom and included more than 4,000 hospitalised COVID-19 patients. Roche-sponsored global trials included the placebo-controlled EMPACTA, COVACTA and REMDACTA studies. There have been no new safety signals identified for Actemra/RoActemra in any of these studies. The most common adverse reactions seen (incidence = 3%) are constipation, anxiety, diarrhoea, insomnia, hypertension and nausea. The?U.S. FDA Letter of?Authorisation?and Fact Sheets for?patients?and?health care professionals?are available for download with the latest information on this EUA.

In these exceptional times, Roche stands together with society, governments, healthcare providers and all those working to overcome the pandemic. About the Emergency Use Authorization (EUA) for?Actemra/RoActemra Actemra/RoActemra has not been approved by the U.S. FDA in this setting, but the U.S. FDA has made Actemra/RoActemra available under an emergency access mechanism called an EUA as a treatment for certain patients with COVID-19. There is limited information known about the safety or effectiveness of using Actemra/RoActemra to treat people in the hospital with COVID-19. The EUA is supported by a Secretary of Health and Human Services (HHS) declaration that circumstances exist to justify the emergency use of drugs and biological products during the COVID-19 pandemic. The authorisation is temporary and does not replace the formal review and approval process. Actemra/RoActemra is authorised under the EUA only for the duration of the declaration that circumstances exist justifying the authorisation of the emergency use of Actemra/RoActemra under Section 564(b)(1) of the Act, 21 U.S.C.? 360bbb-3(b)(1), unless the authorisation is terminated or revoked sooner. Roche has existing distribution channels established to ship Actemra/RoActemra to hospitals across the United States. About the?Actemra/RoActemra?COVID-19 Clinical Trial?Programme Roche?s clinical trial programme evaluated the safety and efficacy of Actemra/RoActemra in hospitalised patients with COVID-19. Actemra/RoActemra is not approved for this use in any country and there is limited information known about the safety or effectiveness of using Actemra to treat people in the hospital with COVID-19. COVACTA and EMPACTA were the first two global phase III, multicentre, randomised, placebo-controlled studies of Actemra/RoActemra in patients hospitalised with COVID-19 associated pneumonia. COVACTA was conducted in collaboration with the Biomedical Advanced Research and Development Authority (BARDA), part of the Office of the Assistant Secretary for Preparedness and Response at the United States Department of Health and Human Services (HHS). EMPACTA aimed to address research questions about the safety and efficacy of Actemra in underserved populations by emphasising enrollment from minority patients often underrepresented in clinical trials. Both studies were published in the New England Journal of Medicine. Roche also partnered with Gilead Sciences, Inc., on REMDACTA, a phase III, randomised, double-blind, multicentre study to evaluate the safety and efficacy of Actemra/RoActemra plus Veklury? (remdesivir), versus placebo plus Veklury, in hospitalised patients with severe COVID-19 associated pneumonia. About?Actemra/RoActemra Actemra/RoActemra was the first humanised interleukin-6 (IL-6) receptor antagonist approved for the treatment of adult patients with moderately to severely active rheumatoid arthritis (RA) who have used one or more disease-modifying antirheumatic drugs (DMARDs), such as methotrexate (MTX), that did not provide enough relief. The extensive Actemra/RoActemra RA IV clinical development programme included five phase III clinical studies and enrolled more than 4,000 people with RA in 41 countries. The Actemra/RoActemra RA subcutaneous clinical development programme included two phase III clinical studies and enrolled more than 1,800 people with RA in 33 countries. Actemra/RoActemra subcutaneous injection is also approved for the treatment of adult patients with giant cell arteritis (GCA), for the treatment of patients two years of age and older with active polyarticular juvenile idiopathic arthritis (PJIA) or active systemic juvenile idiopathic arthritis (SJIA), and for slowing the rate of decline in pulmonary function in adult patients with systemic sclerosis-associated interstitial lung disease (SSc-ILD). In addition, Actemra/RoActemra is also approved in the IV formulation for patients two years of age and older with active PJIA, SJIA or CAR T cell-induced cytokine release syndrome (CRS). Actemra/RoActemra is not approved for subcutaneous use in people with CRS. It is not known if Actemra is safe and effective in children with PJIA, SJIA or CRS under two years of age or in children with conditions other than PJIA, SJIA or CRS. Actemra is intended for use under the guidance of a healthcare practitioner. About Roche?s response to the COVID-19 pandemic As a leading healthcare company we are doing all we can to support countries in their fight against COVID-19 and minimising its impact. We have developed a growing number of diagnostic solutions that help to detect and diagnose the infection, as well as providing digital support to healthcare systems. We also continue to identify, develop and support potential therapies which can play a role in treating the disease. The impact of COVID-19 goes beyond those who contract it. That is why we are working with healthcare providers, laboratories, authorities and organisations to help make sure patients continue to receive the tests, treatment and care they need during these challenging times. Building on a longstanding tradition of partnerships, we are working together with governments and others to make healthcare stronger and more sustainable in the future. Reliable, high-quality testing is essential to help healthcare systems overcome this pandemic and Roche has so far launched 16 diagnostics solutions to help minimise the impact of COVID-19. As soon as the novel SARS-CoV-2 virus was sequenced in early 2020, we got to work. On 13 March 2020 we became the first company to receive U.S. Food and Drug Administration (FDA) Emergency Use Authorization (EUA) for a high-volume molecular test to detect the virus. Since then, we have continued to add a range of diagnostics solutions to our global portfolio to help in the fight against COVID-19. In addition to the gold standard PCR test, we have developed antigen tests to help diagnose the virus in settings where there is limited molecular laboratory infrastructure, rapid antigen where the virus can be detected on the spot, tests that can test for both flu and COVID-19 at the same time, both high throughput and at the point of care, and tests that can detect virus antibodies that can help monitor the spread of the virus and can also support in vaccine development. On 16 March 2021 the SARS-CoV-2 variant test was launched, designed to detect key spike mutations. Aside from these tests we have also looked at how we can support care for patients who have COVID-19, receiving an U.S. FDA EUA for the Elecsys? IL-6 test to assist in identifying severe inflammatory response in patients with confirmed COVID-19, as well as launching Roche v-TAC, a digital algorithm that could help simplify the screening, diagnosis and monitoring of respiratory-compromised patients with COVID-19. Roche is working closely with governments and health authorities around the world, and has significantly increased production to support availability of tests globally. Roche is actively involved in understanding the potential of the existing portfolio and is researching options for the future. In 2020, Roche entered into a number of new partnerships, including with Gilead, Regeneron and Atea, to develop, manufacture and distribute molecules that can potentially both treat and prevent COVID-19. In October, Roche announced a partnership with Atea Pharmaceuticals to jointly develop the investigational compound AT-527. If approved, Atea will distribute AT-527 in the United States (US) and Roche will be responsible for global manufacturing and distribution outside the US. Atea?s compound has the potential to be the first oral antiviral to treat COVID-19 patients outside the hospital setting as well as in the hospital. Its anticipated formulation (pill) may help to facilitate access to a broad patient population. In November, our partner Regeneron received U.S. FDA EUA for casirivimab and imdevimab, its investigational antiviral antibody combination, for the treatment of recently diagnosed patients with mild to moderate COVID-19 who are at high risk of progressing to severe COVID-19 and/or hospitalisation. The antibody cocktail has been studied in two phase I-III adaptive clinical trials for the treatment of COVID-19 and in a phase III trial for the prevention of the disease. As part of the global partnership with Regeneron, we are committing a significant amount of manufacturing capacity and are working to expand supply of this antibody combination beyond the US to as many people as possible. In addition, we are exploring the potential of our investigational molecules and existing portfolio: For example, Roche has initiated three global phase III clinical trials investigating the safety and efficacy of Actemra/RoActemra in COVID-19 associated pneumonia (COVACTA, EMPACTA and REMDACTA). Roche will continue to monitor the evolving clinical evidence for Actemra/RoActemra in this setting.
