Basel, 2 September 2019 - Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced that the phase III MINISTONE-2 study showed that one-dose XofluzaTM (baloxavir marboxil) was a well-tolerated and effective potential treatment for flu in otherwise healthy children aged one to less than 12 years old. The study met its primary endpoint, which evaluated the proportion of patients with adverse events (AEs) or severe AEs up to study day 29, demonstrating results consistent with the safety profile of Xofluza. In Xofluza-treated participants, 46.1% experienced at least one treatment-emergent AE compared to 53.4% in the oseltamivir arm. The study also showed the efficacy of Xofluza to be comparable to oseltamivir (a proven effective treatment for children with flu). In addition, consistent with data in adults and adolescents, Xofluza reduced the length of time that the flu virus continued to be released from the body by more than two days compared with oseltamivir (viral shedding; median time of 24.2 hours versus 75.8 hours, respectively). Full results of the study were presented as a late-breaking abstract during the OPTIONS X 2019 congress in Singapore on Sunday 1 September, 2019 (Abstract #11756).

At the event, Dr. Harsh Vardhan stated that: “The ‘Eat Right India’ movement of FSSAI takes inspiration from the vision of the Hon. Prime Minister Shri Narendra Modji ji of giving to the people of this country a ‘New India’ by 2022 that includes health, social security and nutrition. The Prime Minister has also acknowledged the ‘Eat Right Movement’ of FSSAI in his “Mann ki Baat” address”. He further stated that health does not merely mean absence of disease and infirmity but its definition also includes the presence of physical, mental, emotional and spiritual wellness, and food plays a vital role in all these components. Dr Harsh Vardhan said that the primacy given to nutrition and healthy eating practices by the Government forms the pivot of the Poshan Maah, which was observed in September, where many ministries and stakeholders joined hands for enhancing awareness about issues surrounding nutrition.

“Each year approximately one in three children develop flu, and their less mature immune systems mean they are slower to fight the infection and more vulnerable to complications,” said Sandra Horning, MD, Roche’s Chief Medical Officer and Head of Global Product Development. “We are committed to developing new, more convenient treatment options for children with flu and look forward to sharing these data with global health authorities.”.

MINISTONE-2 is the first global phase III study for Xofluza in children. It showed that Xofluza was comparable to oseltamivir in relation to key secondary endpoints, including time to alleviation of influenza signs and symptoms (median 138.1 hours vs. 150.0 hours).

This is the fourth positive phase III study for Xofluza, which has now demonstrated benefit in several populations (otherwise-healthy, high-risk, children) and treatment settings (symptomatic, post-exposure prophylaxis).1-4 Xofluza is being further studied in an ongoing phase III development programme, including children under one year, severely ill hospitalised people with flu, and to assess the potential to reduce transmission of flu from an infected person to healthy people.

MINISTONE-2 is a phase III, multicentre, randomised, double-blind study that evaluated the safety, pharmacokinetics and efficacy of one dose of Xofluza compared with oseltamivir in otherwise healthy children aged one to less than 12 years with influenza infection and displaying influenza symptoms (temperature of 38°C or over, and one or more respiratory symptom).

Participants enrolled in the study were recruited in parallel into two cohorts: patients aged five to less than 12 years and patients aged one to less than five years. Patients in both cohorts were randomly assigned to receive one dose of Xofluza (2mg/kg for patients under 20kg or 40mg for patients 20kg or over) or oseltamivir twice a day over five days (dosing according to body weight). The primary endpoint of the study was the proportion of patients with adverse events or severe adverse events up to study day 29. Secondary endpoints included pharmacokinetics, time to alleviation of influenza signs and symptoms, and duration of symptoms, including fever.

Xofluza is a first-in-class, one-dose oral medicine with a novel proposed mechanism of action that has demonstrated efficacy in a wide range of influenza viruses, including in vitro activity against oseltamivir-resistant strains and avian strains (H7N9, H5N1) in non-clinical studies.8,9 Unlike other currently available antiviral treatments, Xofluza is the first in a new class of antivirals designed to inhibit the CAP-dependent endonuclease protein, which is essential for viral replication.

Xofluza is currently approved in several countries, including the United States (US), for the treatment of acute, uncomplicated influenza in people 12 years of age and older. In addition, a supplemental New Drug Application (sNDA) for Xofluza as a one-dose oral treatment for people at high risk of complications from flu is under review by the FDA and a decision is expected by 4 November 2019.

Xofluza is being further studied in a phase III development programme, including children under the age of one (NCT03653364), severely ill, hospitalised patients (NCT03684044), as well as to assess the potential to reduce transmission of flu from an infected person to healthy people (NCT03969212).

Xofluza was discovered by Shionogi & Co., Ltd. and is being further developed and commercialised globally in collaboration with the Roche Group (which includes Genentech in the US) and Shionogi & Co., Ltd. Under the terms of this agreement, Roche holds worldwide rights to Xofluza excluding Japan and Taiwan, where rights will be retained exclusively by Shionogi & Co., Ltd.

Influenza, or flu, is one of the most common, yet serious, infectious diseases, representing a significant threat to public health.10 Globally, seasonal epidemics result in 3 to 5 million cases of severe disease, millions of hospitalisations and up to 650,000 deaths every year.11-15 Children are at a particularly high risk of developing flu, with an estimated global rate of 20–30% compared with 5–10% in adults, and are more vulnerable to complications such as breathing problems, pneumonia and, in some cases, even death.5,16 Due to these complications, approximately one million children under five years old are hospitalised globally every year.

Infectious diseases caused by viral or bacterial pathogens are a major cause of death and morbidity worldwide, and constitute an ever-growing medical need. As such, they form a core area of research and development at Roche, with clinical development programmes focused on hepatitis B, influenza and multi-drug resistant bacterial infections. We are committed to developing medicines that aim to be transformative, personalised, and accessible.

About Roche - Roche is a global pioneer in pharmaceuticals and diagnostics focused on advancing science to improve people’s lives. The combined strengths of pharmaceuticals and diagnostics under one roof have made Roche the leader in personalised healthcare – a strategy that aims to fit the right treatment to each patient in the best way possible.
