TOKYO, June 1 (Reuters) – Japan’s Shionogi & Co said on Monday the U.S. ​Food and Drug Administration ‌has approved its oral antiviral Ensitrelvir, commercially known as Xocova, for the preventive treatment ‌of ​individuals who ⁠have been exposed ⁠to COVID-19.

“XOCOVA is the first and only oral option clinically proven to help ​prevent symptomatic COVID-19 after exposure among study ⁠participants regardless of ⁠vaccination status,” Nathan ​McCutcheon, CEO of Shionogi’s U.S. ​unit, said in a statement.

The ‌financial impact of the FDA approval of Xocova in the current fiscal ⁠year ending March 2027 has already been reflected in the earnings ⁠forecast ‌announced last month, ⁠Shionogi said.

Shionogi shares ​were ‌down 4.5% on Monday, ​while ⁠the benchmark Nikkei 225 index was up 0.9%.
