|China National Medical Products Administration Approves Descovy® (Emtricitabine, Tenofovir Alafenamide) for the Treatment of HIV-1 Infection|
– Fixed-Dose Combination HIV Treatment Backbone Can Be Paired with Range of Third Agents –
TAF is a novel, targeted prodrug of tenofovir that has demonstrated antiviral efficacy similar to Gilead’s TDF (tenofovir disoproxil fumarate 300 mg) but at one-tenth of the dose. Data show that because TAF has greater plasma stability and more efficiently delivers tenofovir to peripheral blood mononuclear cells compared to TDF, it can be given at a lower dose, resulting in less tenofovir in the bloodstream. In clinical trials, TAF demonstrated improved renal and bone laboratory safety parameters compared to TDF.
“Advances in HIV therapies have changed the way physicians think about
long-term care. As the number of people aging with HIV continues to
grow, it is critical that treatments are designed to help address
evolving health needs,” said Professor Li Taisheng,
In 2017, there were 134,512 people newly diagnosed with HIV in

The approval of Descovy is supported by 144-week data from two pivotal Phase 3 studies (Studies 104 and 111) in which the F/TAF-based regimen (administered as Genvoya; elvitegravir 150 mg/cobicistat 150 mg/emtricitabine 200 mg/tenofovir alafenamide 10 mg, E/C/F/TAF) met its primary objective of non-inferiority compared to an F/TDF-based regimen (administered as Stribild®; elvitegravir 150 mg/cobicistat 150 mg/emtricitabine 200 mg/tenofovir disoproxil fumarate 300 mg, E/C/F/TDF) among treatment naïve adult patients. Tests of certain renal and bone laboratory parameters favored the F/TAF-based regimen over the F/TDF-based regimen.
The approval also is supported by a Phase 3 study (Study 109) evaluating the F/TAF-based regimen (administered as Genvoya) among virologically suppressed adult patients who switched from F/TDF-based regimens. In the study, the F/TAF-based regimen was found to be statistically non-inferior to the F/TDF-based regimens and demonstrated improvements in certain bone and renal laboratory parameters compared to the F/TDF-based regimens. Additionally, the approval is supported by data from Phase 3 studies evaluating the F/TAF-based regimen (administered as Genvoya) among virologically suppressed adults with mild-to-moderate renal impairment and among treatment naïve adolescents.
