Drug Indication

Dovato is approved both for adults who have not previously received treatment for HIV and for those with an undetectable viral load who wish to switch to a new antiretroviral regimen.

The U.S. Department of Health and Human Services (DHHS) Panel on Antiretroviral Guidelines for Adults and Adolescents lists Dovato as a recommended initial regimen, except for people with a viral load above 500,000, those with hepatitis B virus (HBV) and those who are starting treatment right away, before the results of HIV resistance testing or HBV testing are available. The guidelines also list Dovato as a successful strategy for switching from a three-drug to a two-drug regimen.

General Info

Dovato, dolutegravir, lamivudineDovato (dolutegravir + lamivudine) is single-tablet regimen for HIV. It contains two different types of antiretoviral drugs: one integrase inhibitor and one nucleoside reverse transcriptase inhibitor (NRTI). The combination pill contains two currently approved HIV medications: dolutegravir (sold separately as Tivicay) + lamivudine (sold separately as Epivir). It was approved by U.S. Food and Drug Administration for frst-time treatment in April 2019, with an expanded indication as a switch option in August 2020.

Approval of Dovato was based on findings from the Phase III GEMINI-1 and GEMINI-2 trials. Together, the trials included 1,433 first-timers to HIV treatment. They were randomized to receive either the components of Dovato or a three-drug regimen of dolutegravir plus tenofovir disoproxil fumarate/emtricitabine (the drugs in Truvada). The two regimens suppressed HIV at a comparably high rate after 48 weeks.
