US FDA approves dolutegravir/lamivudine (Dovato) as switch option

Simon Collins, HIV i-Base

On 6 August 2020, the US FDA extended the indication for the two-drug fixed dose combination of dolutegravir/lamivudine (DTG/3TC) to include use as a switch combination for people stable on other treatment.

DTG/3TC was initially only approved by the FDA in April 2019 as first-line antiretroviral treatment (ART).

The new use as a switch option is restricted to people who have an undetectable viral load on their current ART, and who do not have a history of treatment failure or resistance to either drug.

In Europe, DTG/3TC is already approved as both first-line ART and as a switch option so long as there is no resistance to either drug.

Dolutegravir/3TC is manufactured by ViiV Healthcare and is marketed with the tradename Dovato.
