A Japanese company reports that it has developed a drug that can kill the influenza virus within 1 day. However, even if the drug proves successful, it likely will not be available in the United States until 2019 at the earliest. According to the company, a late-stage trial involving Japanese and American influenza patients found that for people who took the experimental Shionogi compound, the median time to eliminate the virus was 24 hours. That is much faster than other influenza drugs on the market, and it only requires one dose. Both the experimental compound and oseltamivir phosphate (Tamiflu—Roche), which requires two doses a day for 5 days, take approximately the same amount of time to entirely contain symptoms of influenza; however, Shionogi claims that its compound offered immediate relief more quickly. Shionogi and Roche, which has acquired the international license to distribute Shionogi's experimental drug, are in the final stages of conducting a second late-stage global trial. Other companies are testing new compounds to test influenza A; but Shionogi's is furthest along.
