Shionogi : Announces FDA Approval of XOFLUZA for the prevention of Influenza following contact with an infected person

11/25/2020 | 09:53am EST

OSAKA - Shionogi & Co., Ltd. (Head Office: Osaka, Japan; President and CEO: Isao Teshirogi, Ph.D.; hereafter 'Shionogi') today announced that its License Partner F. Hoffmann-La Roche Ltd. (Head Office: Basel, Switzerland; CEO: Severin Schwan, L.L.D.; hereafter 'Roche') holds worldwide rights to Xofluza excluding Japan and Taiwan, has received the U.S. Food and Drug Administration (FDA) approval for a supplemental New Drug Applications (sNDA) for Xofluza as a treatment to prevent influenza in people 12 years of age and older following contact with someone with influenza.

Xofluza is the first single-dose influenza medicine approved for post-exposure prophylaxis. This approval was determined based on the phase III study, BLOCKSTONE.1 The approval was in advance of the Prescription Drug User Fee Act (PDUFA) date for an FDA decision of November 23, 2020.

Post-exposure prophylaxis with single-dose Xofluza was evaluated in the BLOCKSTONE study, which was recently published in The New England Journal of Medicine. In the study, Xofluza was compared with placebo as a preventive treatment for household members (adults and children) who were living with someone with influenza. The proportion of subjects who became infected with influenza virus and showed fever and at least one respiratory symptom was 1.9% in subjects treated with Xofluza and 13.6% in the placebo-treated group. Xofluza was well tolerated in this study and no new safety signals were identified.

Shionogi and the Roche Group (hereafter 'Roche') are in a license and collaboration agreement to further develop and commercialize Xofluza. Under the terms of this agreement, Roche holds worldwide rights to Xofluza excluding Japan and Taiwan, where the rights are retained exclusively by Shionogi.

In the U.S., Xofluza is already FDA-approved to treat acute influenza in people 12 years of age and older who have had influenza symptoms for no more than 48 hours and who are otherwise healthy or at high risk of developing influenza-related complications.2, 3 In the United States, Xofluza is the only drug approved for high-risk patients with influenza, which alongside the new approval as a preventive treatment, may also potentially mitigate the burden of the upcoming influenza season on the U.S. healthcare system amid the COVID-19 pandemic. The Centers for Disease Control and Prevention (CDC) guidelines list Xofluza as a treatment option for outpatients with influenza without complications.4 Additionally, Roche is determining a path forward with the FDA for an indication for Xofluza as a treatment for acute uncomplicated influenza in otherwise healthy children (12 years of age) and for the prevention of influenza in the same age group who have been exposed to influenza. Xofluza is currently not approved for use in this population.

About the BLOCKSTONE Study1

BLOCKSTONE was a Phase III, double blind, multicenter, randomized, placebo-controlled, post-exposure prophylaxis study that evaluated a single-dose of Xofluza compared with placebo in household members (adults and children) who were living with someone with an influenza infection confirmed by a rapid influenza diagnostic test (the 'index patient'). The study was conducted by Shionogi & Co., Ltd. during the 2018-2019 flu season in Japan.

Those diagnosed with influenza were required to have onset of symptoms within less than 48 hours, and participants were required to have lived with those diagnosed for more than 48 hours. The participants were randomised to receive a single-dose of Xofluza (dosed according to body weight) or placebo as a preventive measure against developing influenza.

Xofluza showed a statistically significant prophylactic effect on influenza after a single-dose in people exposed to an infected household contact. The proportion of household members 12 years of age and older who developed influenza was 1.9% in participants treated with Xofluza and 13.6% in the placebo-treated group. Xofluza was well tolerated in this study and no new safety signals were identified.

About Xofluza (baloxavir marboxil)

Xofluza discovered by Shionogi, has a novel mechanism of action that inhibits the cap-dependent endonuclease in the polymerase acidic (PA) protein (in the United States Prescribing Information, this enzyme is stated as polymerase acidic endonuclease), an enzyme essential for viral replication. Xofluza is a single-dose oral treatment for influenza, which is different from all other currently available antiviral treatments. In non-clinical studies, Xofluza demonstrated an antiviral effect against a wide range of influenza viruses including oseltamivir-resistant strains and avian strains (H7N9, H5N1).6, 7 Xofluza is available in many other countries for the treatment of influenza types A and B, including Japan and the U.S. For more information about the use in the U.S., please refer to the Xofluza website. Roche is now conducting a phase III development program investigating Xofluza in several populations, including children under the age of one year (NCT03653364), as well as to assess the potential to reduce transmission of influenza from an infected person to healthy people (NCT03969212). Shionogi submitted a sNDA for the post-exposure prophylaxis on October 16, 2019 in Japan and also filed sNDA for Xofluza in Taiwan for the post-exposure prophylaxis of influenza virus infection in adults and children 12 years of age and older on March 31, 2020 based on the positive results from the Phase III BLOCKSTONE study.8, 9
