The Janssen Pharmaceutical Companies of Johnson & Johnson is unveiling new 96-week data for Symtuza (darunavir 200 mg, cobicistat 150 mg, emtricitabine 200mg, and tenofovir alafenamide 10 mg; D/C/F/TAF), a single-tablet regimen for the treatment of human immunodeficiency virus type 1 (HIV-1) in treatment-naïve and certain virologically suppressed adults, in a presentation at IDWeek 2018 in San Francisco.
According to the company, results from the pivotal Phase 3 EMERALD study demonstrate that in adults with HIV-1 who are virologically suppressed, switching to Symtuza resulted in maintained high virologic suppression (91%, 692/763) and low virologic failure (1%, 9/763) at week 96 (per FDA-Snapshot); low cumulative virologic rebound (3.1%, 24/763); and no resistance development, up to 96-weeks.1
“The 96-week results from the EMERALD study demonstrate that Symtuza can offer clinically appropriate people living with HIV a single-tablet option that may help them maintain high rates of virologic suppression over time,” said Joseph Eron, M.D., professor of medicine and director, clinical core, University of North Carolina Center for AIDS Research, Chapel Hill, NC.
This 96-week extension study, which follows on from the earlier 24- and 48-week results,2,3,4 reinforced the long-term efficacy, resistance and safety profile of Symtuza as a treatment for virologically suppressed adults with HIV-1.
On September 25, 2017, the drug was approved for the treatment of HIV-1 infection by the European Commission based on results from a bioequivalence study that compared Symtuza with the combined administration of the separate agents darunavir [D] 800mg, cobicistat [C] 150mg, and emtricitabine/tenofovir alafenamide [FTC/TAF] 200mg/10mg fixed-dose combination.5,6
