ViiV Healthcare has announced that the European Commission has granted marketing authorisation for Dovato (dolutegravir/lamivudine) for the treatment of HIV-1 infection in adults and adolescents above 12 years of age weighing at least 40kg, with no known or suspected resistance to the integrase inhibitor class, or lamivudine.
Deborah Waterhouse, CEO, ViiV Healthcare, said: “For many years, the standard of care for people living with HIV in Europe has been a three-drug regimen. The data from our dolutegravir-based 2-drug regimen development programme challenges this, and with the authorisation of Dovato, people living with HIV can for the first time start treatment on a once-daily, single-pill, two-drug regimen with the knowledge that efficacy is non-inferior to a three-drug regimen whilst containing fewer antiretrovirals. Dovato strengthens ViiV Healthcare’s industry-leading portfolio of innovative treatment approaches for people living with HIV.”
Marketing authorisation for Dovato is supported by data from the landmark global GEMINI 1 & 2 studies that included more than 1400 HIV-1 infected adults. In these studies, dolutegravir (DTG) + lamivudine (3TC) demonstrated non-inferior efficacy based on plasma HIV-1 RNA <50 copies per millilitre (c/mL), a standard measure of HIV control, at Week 48 when compared to a three-drug regimen of dolutegravir and two nucleoside reverse transcriptase inhibitors (NRTIs), tenofovir disoproxil fumarate/emtricitabine (TDF/FTC), in treatment-naïve, HIV-1 infected adults. The safety results for dolutegravir + lamivudine seen in GEMINI 1 and 2 were consistent with the product labelling for dolutegravir and lamivudine. Four patients (1%) in both the DTG + 3TC, and the DTG + TDF/FTC, study arms experienced drug-related serious adverse events, and 15 patients (2%) in the DTG + 3TC arm and 16 patients (2%) in the DTG + TDF/FTC arm had adverse events that led to discontinuation. The most common adverse reactions included headache, diarrhoea, nausea, insomnia, and fatigue. No patient who experienced virologic failure in either treatment arm developed treatment-emergent resistance also up to Week 48.
John C Pottage, Jr, MD Chief Scientific and Medical Officer, ViiV Healthcare said: “The marketing authorisation of Dovato in Europe marks a significant development for people living with HIV. This treatment allows individuals to take a 2-drug regimen in a single pill with dolutegravir at the core, building on the established potency and safety profiles of dolutegravir and lamivudine. ViiV Healthcare’s ambition and innovative R&D programme aims to reduce the number of HIV drugs people living with HIV take over a lifetime and Dovato is an important addition to our portfolio of medicines to support this aim.”
