GSK releases positive interim results from the DAWNING study on efficacy of dolutegravir (Tivicay)
18 August 2017
ViiV Healthcare1, a joint venture in which GSK is the majority shareholder, released the interim results from the DAWNING study2 at the recent International AIDS Conference. The study shows that for HIV-infected patients, the antiviral efficacy of the regimen of dolutegravir (Tivicay3) + 2 nucleoside reverse transcriptase inhibitors (NRTIs) is superior to that of the lopinavir/ritonavir + 2 NRTIs regimen currently recommended by WHO.
As of the end of June 2016, there are about 56,000 people living with HIV in China receiving the lopinavir/ritonavir + 2 NRTIs treatment. DAWNING shows that the regimen of dolutegravir (Tivicay), which has been launched in China, plus 2 NRTIs, is more efficacious than the current standard of care.
DAWNING is a multinational clinical trial, with four Chinese hospitals located in Beijing, Shanghai and Guangzhou participating in it. Data from the study includes clinical research data on Chinese people living with HIV and research data contributed by clinical doctors in China.
The already published SINGLE study shows that the regimen of dolutegravir (Tivicay) + 2 NRTIs (abacavir and lamivudine) has significantly higher efficacy and better tolerance than the first line regimen of efavirine +2 NRTIs (tenofovir+ emtricitabine).
Interviewed at the International AIDS Conference, Professor Fujie Zhang from Beijing Ditan Hospital of Captical Medical University, DAWNING’s primary investigator in China, said: “DAWNING is a milestone multinational clinical trial. At present, the recommended second line regimen in both developed and developing countries is still protease inhibitor plus booster +2 NRTIs. DAWNING shows that in terms of efficacy and tolerance, the protease inhibitor-sparing regimen of dolutegravir + 2 NRTIs is superior to the regimen of lopinavir/ritonavir + 2 NRTIs currently recommended by WHO. I am glad that a better second line regimen is now available to people living with HIV. ”
Professor Fujie Zhang also said: “Integrase inhibitors such as dolutegravir offer high efficacy, good tolerance, zero resistance, convenience and less drug drug interation (DDI), thus better meeting the varied treatment needs of doctors and people living with HIV. HIV treatment is entering an era of integrase inhibitors such as dolutegravir, so I hope that integrase inhibitors will become the agent of choice for not only second line but alsofirst line regimen in China.”
Dr. Wim Swyzen, VP & Country Medical Director for GSK China and Hong Kong, said: “Results from both DAWNING and SINGLE studies prove that the new regimen with dolutegravir (Tivicay) as core agent has superior efficacy to the first and second line regimens currently in place in China. The studies have also reaffirmed the important position of dolutegravir (Tivicay) in HIV treatment. GSK is working with relevant Chinese authorities to increase the access & affordabilty of Tivicay to benefit more Chinese people living with HIV in the near future.”
