London, UK – 25 October 2013:

ViiV Healthcare today announced the submission of a regulatory application in Europe for its investigational single-tablet regimen (STR) combining dolutegravir (DTG), abacavir (ABC) and lamivudine (3TC) for the treatment of people living with HIV. This Marketing Authorisation Application (MAA) follows the announcement earlier this week of a similar regulatory submission in the US¹.

“People living with HIV and their doctors seek to use appropriate treatment options for the individual, while also trying to minimise the number of pills required for effective and acceptable antiretroviral treatment,” said Dr John Pottage, Chief Medical Officer, ViiV Healthcare. “This submission, together with the New Drug Application submitted recently to the US Food and Drug Administration, aims to make a complete dolutegravir-based regimen available for the first time in a single once-daily pill.”

Dolutegravir was approved by the US Food and Drug Administration in August 2013 under the brand name Tivicay^® for use in combination with other antiretroviral agents for the treatment of HIV-1 in adults and children aged 12 years and older weighing at least 40 kg (approx. 88 lbs). The review of the MAA for dolutegravir (DTG), submitted in Europe in December 2012, is in progress with the European Medicines Agency (EMA). A fixed-dose combination of ABC/3TC for use in antiretroviral combination therapy is marketed by ViiV Healthcare in Europe under the brand name Kivexa^® as a once-daily tablet. The investigational STR combining DTG/ABC/3TC has sometimes been referred to as “Trii”.
