Public Summary SwissPAR – Xofluza®

Public Summary SwissPAR dated 10.08.2020

Xofluza® (active substance: baloxavir marboxil)

First authorisation in Switzerland: 19.02.2020

Medicine (film-coated tablets) for the treatment of patients 12 years of age and older with uncomplicated influenza (flu), who have shown flu symptoms for no more than 48 hours and who are otherwise healthy or at high risk of developing flu-related complications.

Information on authorisation

The medicine Xofluza, containing the active substance baloxavir marboxil, was authorised in connection with the work-sharing in-itiative of the ACSS Consortium. This work-sharing initiative is a collaborative project between the drug regulatory authorities in Australia (Therapeutic Goods Administration, TGA), Canada (Health Canada, HC), Singapore (Health Sciences Authority, HSA) and Swissmedic and the pharmaceutical industry. The work-sharing initiative coordinates the assessment of authorisation applications for new active substances that have been submitted in at least two of the four countries.

The authorisation application for Xofluza was submitted for assessment to the regulatory authorities in Canada, Australia and Switzerland. Each country assessed a part of the application and then shared and discussed the results. At the end of the process, each authority decided on the application independently.

Accordingly, Swissmedic did not conduct a comprehensive scientific assessment, but considered, and in this case accepted, the results of the assessments by the foreign reference authorities. Accordingly, and since Swissmedic has not produced a complete SwissPAR (Swiss Public Assessment Report), it cannot issue a complete Public Summary SwissPAR. Swissmedic therefore refers to the publications issued by the authorities involved:

Why the medicine has been authorised

Various studies have shown that the medicine Xofluza with the active substance baloxavir marboxil alleviates flu symptoms faster than a placebo. Since the available data demonstrate a positive benefit-risk profile, Swissmedic has authorised the medicine Xofluza with the active substance baloxavir marboxil for use in Switzerland.
