Fosdevirine, also known as GSK2248761 and IDX899, a Highly Potent Anti-HIV Non-nucleoside Reverse Transcriptase Inhibitor having an EC50 of 11 nM against the Y181C/K103N double mutant. GSK2248761 is a novel, once-daily (QD), next-generation nonnucleoside reverse transcriptase inhibitor (NNRTI) with activity against efavirenz-resistant strains. GSK2248761 at 100 to 800 mg QD for 7 days was well tolerated, demonstrated potent antiviral activity in treatment-naive HIV-infected subjects, and had favorable PK and resistance profiles. GSK2248761 is no longer in clinical development.
