Anti-influenza therapeutic regimen with a brand-new mechanism of action
As RNA viruses, influenza viruses are classified into types A, B, C and D based on differences in proteins and matrix proteins. In the drug treatment field, specific anti-influenza drugs can be used for the prevention of influenza and the relief of influenza symptoms in patients. In the current anti-influenza drug area in China, the neuraminidase inhibitor: oseltamivir phosphate is the anti-influenza drug of choice, accounting for a major market share.
Roche’s baloxavir marboxil is an ester prodrug, which is hydrolyzed into the active substance baloxavir marboxil in the body and achieves the anti-influenza virus purpose by inhibiting polymerase acidic (PA) endonuclease necessary for the transcription of the influenza virus genome. It has strong inhibitory activity against influenza A and B viruses and possesses a brand-new anti-influenza mechanism of action.
The only single-dose oral drug approved for influenza treatment at present
First developed by Shionogi & Co., Ltd., Baloxavir Marboxil Tablets received Japan PMDA’s priority review designation in Nov. 2015 for single-dose treatment of acute influenza in patients aged ≥12 years without complications and was later approved for marketing in Japan in Feb. 2018 through accelerated approval for the treatment of influenza A and B, with the trade name Xofluza.
Roche reached a cooperation agreement with Shionogi in Feb. 2016 to be responsible for the R&D of the drug outside Japan and Taiwan, China Region of China, and have the right to commercially promote it outside Japan and Taiwan, China Region of China.
Roche’s Genentech received the FDA’s priority review designation for Baloxavir Marboxil Tablets in June 2018 and the approval for marketing it in Oct. 2018, with the trade name Xofluza.
In terms of fighting influenza, Baloxavir Marboxil Tablets can reduce the relief time of influenza symptoms by more than one day with just a single dose taken orally, which brings a more convenient anti-influenza therapeutic regimen for patients. By comparison, the preferred anti-influenza in China: oseltamivir phosphate requires patients to take the drug twice a day for 5 days. Xofluza is the first and currently the only single-dose oral drug approved for the treatment of influenza and also the first anti-influenza virus drug with a brand-new mechanism of action approved by the FDA in the recent 20 years.
