A recently granted patent (Publication Number: US11918560B2) discloses a method for treating coronavirus infections by administering a composition containing WX-671, a serine protease inhibitor. The method involves administering an effective amount of WX-671, either in its free base form or hydrogen sulfate salt form, along with a pharmaceutically-acceptable carrier material in a unit dosage suitable for oral administration. The dosage form can be a solid dosage form, such as a capsule, with specific dosing regimens outlined for different variants of coronavirus.

Furthermore, the patent also covers the treatment of coronavirus infections mediated by a trypsin-like serine protease, specifically type II transmembrane serine proteases (TTSP), in a cell or tissue system. The method involves administering WX-671, preferably in its hydrogen sulfate salt form, along with a carrier material in a unit dosage form suitable for oral administration. This patent provides a detailed method for treating coronavirus infections by targeting specific proteases involved in the infection process, potentially offering a new avenue for therapeutic intervention in combating the virus.
