ViiV and Shionogi & Co., Ltd. (Head Office: Osaka; President & CEO: Isao Teshirogi, Ph.D.), in accordance with the Co-promotion Agreement in Japan concluded as of December 16, 2013 for this product, have been jointly providing medical information on Tivicay® Tablets 50mg to medical institutions since the date of approval (24
March, 2014).
ViiV and Shionogi aim to contribute further to HIV treatment by providing Tivicay® Tablets 50mg to healthcare professionals and HIV patients in Japan as soon as possible through the co-promotion of this product following the launch today.

Product Characteristics of Tivicay® Tablets 50mg

Tivicay® Tablets 50mg, an integrase inhibitor, prevents replication of HIV by potently inhibiting the activity of integrase, which incorporates HIV DNA into the chromosomes of human immune cells.

Clinical studies outside Japan demonstrated favorable virological effect and tolerability of this product in patients previously treated or untreated with anti-HIV agents. There is evidence that it is less likely to cause drug-resistant viruses.

Tivicay® Tablets 50mg can be orally administered once daily1 without regard to meals, while eliminating the
necessity of adding pharmacokinetic booster; thus, improved adherence can be anticipated.

1 For patients resistant to HIV integrase inhibitors, 50 mg of dolutegravir should be orally administered twice daily.
