Authorisation based on GEMINI pivotal trials in which Dovato achieved non-inferior efficacy compared to a dolutegravir-based, three-drug regimen through 48 weeks, with no cases of resistance.

LONDON, UK I July 03, 2019 I ViiV Healthcare, the global specialist HIV company, majority owned by GlaxoSmithKline, with Pfizer Inc. and Shionogi Limited as shareholders, today 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 40 kg, with no known or suspected resistance to the integrase inhibitor class, or lamivudine.1

Deborah Waterhouse, CEO, ViiV Healthcare, said: “For many years, the standard of care for treatment-naïve people living with HIV in Europe has been a three-drug regimen. The data from our dolutegravir-based two-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.”

With around 25,000 new HIV diagnoses in Europe* every year2, and the fact that today HIV is considered a chronic condition which requires people living with HIV (PLHIV) to remain on antiretroviral (ARV) treatment for life, it is ever more important to provide innovative treatment options.

Marketing Authorisation for Dovato is supported by data from the landmark global GEMINI 1 and 2 studies that included more than 1,400 HIV-1 infected adults. In these studies, dolutegravir and lamivudine 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 and lamivudine seen in GEMINI 1 and 2 were consistent with the product labelling for dolutegravir and lamivudine. Four patients (1%) in both the dolutegravir and lamivudine, and the dolutegravir and TDF/FTC, study arms experienced drug-related serious adverse events, and 15 patients (2%) in the dolutegravir and lamivudine arm and 16 patients (2%) in the dolutegravir and 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 48.3,4

John C. Pottage, Jr, M.D. 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 two-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.”

Dovato (dolutegravir 50 mg/ lamivudine 300 mg tablets) was authorised by the US Food and Drug Administration in April 20195 (please see US Prescribing Information including Box Warning), and further regulatory applications have been submitted worldwide.

Notes to editors

About Dovato (dolutegravir/lamivudine)
Dovato (dolutegravir 50 mg/ lamivudine 300 mg tablets) is authorised in the EU for the treatment of HIV-1 infection in adults and adolescents above 12 years of age weighing at least 40 kg, with no known or suspected resistance to the integrase inhibitor class, or lamivudine.

Dolutegravir/lamivudine is a once-daily, single-pill, two-drug regimen that combines the integrase strand transfer inhibitor (INSTI) dolutegravir (Tivicay, 50 mg) with the nucleoside analogue reverse transcriptase inhibitor (NRTI) lamivudine (Epivir, 300 mg).1

In the US the Food and Drug Administration (FDA) authorised Dovato, a complete, once-daily, single-tablet regimen of dolutegravir (DTG) 50 mg and lamivudine (3TC) 300 mg for the treatment of HIV-1 infection in adults with no antiretroviral (ARV) treatment history and with no known resistance to either DTG or 3TC.5

Like a dolutegravir-based three-drug regimen, Dolutegravir/lamivudine uses two drugs to inhibit the viral cycle at two different sites. INSTIs, like dolutegravir, inhibit HIV replication by preventing the viral DNA from integrating into the genetic material of human immune cells (T-cells). This step is essential in the HIV replication cycle and is also responsible for establishing chronic infection. Lamivudine is an NRTI that works by interfering with the conversion of viral ribonucleic acid (RNA) into deoxyribonucleic acid (DNA) which in turn stops the virus from multiplying.
