ViiV Healthcare, the global specialist HIV company majority owned by GSK, with Pfizer Inc. and Shionogi Limited as shareholders, today announced 96-week data from the TANGO study at the HIV Glasgow 2020 congress showing that the 2-drug regimen (2DR) Dovato (dolutegravir/lamivudine) continued to demonstrate non-inferior efficacy compared to continuation of a tenofovir alafenamide fumarate (TAF)-based regimen of at least three drugs in virologically suppressed adults with HIV-1 who have not previously experienced virologic failure.[1] Data from the study revealed that no participants on Dovato (0/369, 0%) and three participants (3/372, <1%) on the TAF-based regimen met protocol-defined virologic failure, and no participants developed resistance mutations upon failure.

ViiV Healthcare is a global specialist HIV company established in November 2009 by GlaxoSmithKline and Pfizer dedicated to delivering advances in treatment and care for people living with HIV and for people who are at risk of becoming infected with HIV. Shionogi joined in October 2012. The company’s aims are to take a deeper and broader interest in HIV/AIDS than any company has done before and take a new approach to deliver effective and innovative medicines for HIV treatment and prevention, as well as support communities affected by HIV.
