GSK, ViiV Submit Regulatory Applications for HIV Regimen
GSK and ViiV Healthcare announced regulatory submissions to the European Medicines Agency (EMA) and U.S. Food and Drug Administration (FDA) for a single-tablet, two-drug regimen of dolutegravir (Tivicay, ViiV Healthcare) and rilpivirine (Edurant, Janssen Sciences Ireland UC) for the maintenance treatment of HIV-1 infection.
The submissions are based on the SWORD studies that included more than 1,000 patients who previously achieved viral suppression on a three- or four-drug (integrase inhibitor, non-nucleoside reverse transcriptase inhibitor, or protease inhibitor-based) antiretroviral regimen. The results of these studies were presented at the 2017 Conference on Retroviruses and Opportunistic Infections (CROI) in February.
Use of dolutegravir and rilpivirine as a two-drug regimen for HIV-1 maintenance therapy is investigational and not approved anywhere in the world.
A recently acquired priority review voucher was submitted to the FDA along with the dolutegravir and rilpivirine 2-drug regimen New Drug Application (NDA). Under the Prescription Drug User Fee Act, the anticipated target action date is six months after receipt of the application by the FDA. The $130 million cost of the voucher will be reported as an R&D expense in GSK’s Q2 2017 Adjusted results.
