Gilead Submits New Drug Application to U.S. Food and Drug Administration for Single Tablet Regimen for HIV Containing Rilpivirine, Emtricitabine and Tenofovir Alafenamide

(R/F/TAF).....http://www.natap.org/2015/HIV/070215_01.htm .......Under the Prescription Drug User Fee Act (PDUFA), the anticipated target action date for the R/F/TAF NDA is six months after the FDA's acceptance of the filing......R/F/TAF is Gilead's third TAF-based filing in less than a year......
 
.......In addition to R/F/TAF, two other TAF-based HIV treatments are also under FDA review. In November 2014, Gilead filed an NDA for an investigational, once-daily single tablet regimen containing elvitegravir 150 mg, cobicistat 150 mg, emtricitabine 200 mg and TAF 10 mg (E/C/F/TAF). Gilead filed another NDA in April 2015 for two doses of an investigational, fixed-dose combination of emtricitabine and tenofovir alafenamide (200/10 mg and 200/25 mg) (F/TAF) for use in combination with other HIV antiretroviral agents. Under the PDUFA, the FDA has set a target action date of November 5, 2015, for E/C/F/TAF and April 7, 2016, for F/TAF.
 
.............Marketing Authorization Applications in the European Union were fully validated on December 23, 2014, and May 28, 2015, for E/C/F/TAF and F/TAF respectively. Gilead plans to submit a regulatory application for R/F/TAF in the European Union in the third quarter of 2015.
