Bictegravir (INN; BIC, formerly known as GS-9883)[1][2] is a second-generation integrase inhibitor (INSTI) class that was structurally derived from an earlier compound dolutegravir by scientists at Gilead Sciences; in vitro and clinical results were presented by Gilead in the summer of 2016.[3][4] In 2016, bictegravir was in a Phase 3 trial as part of a single tablet regimen in combination with tenofovir alafenamide (TAF) and emtricitabine (FTC) for the treatment of HIV-1 infection[5] and the combination drug bictegravir/emtricitabine/tenofovir alafenamide (Biktarvy) was approved for use in the United States in 2018.[6]

Medical use

Bictegravir is used a in fixed dose combination with tenofovir alafenaminde and emtricitabine for the treatment of HIV-1 infection.[4][7]


Bictegravir should not be used with dofetilide and rifampin.[8] Use of dofetilide with bictegravir increases the concentration of dofetilide, which can lead to life threatening events.[8] Concomitant use of bictegravir and rifampin causes significant interactions because of an effect rifampin has on bictegravir.[8] Bictagravir is metabolized primarily through the liver (CYP3A4), thus inducers of CYP3A4 should be avoided.[4]

Adverse effects

The most common side effects seen in bictegravir use include diarrhea, nausea, and headache.[4]
