Bictegravir

Chemical compound

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]

Quick Facts Clinical data, Other names ...

The combination drug bictegravir/emtricitabine/tenofovir alafenamide (Biktarvy) was approved for use in 2018 in Australia,[6] the European Union[7] and the United States[8] and in 2019 in New Zealand[9] and the United Kingdom;[10] a generic version was approved by the Drugs Controller General of India in 2019.[11] As of 2024, it is recommended as a first-line choice of antiretroviral therapy in several countries, including the European Union,[12] the United Kingdom[13] and the United States.[14]

Medical use

Bictegravir is used a in fixed dose combination with tenofovir alafenamide and emtricitabine for the treatment of HIV-1 infection.[4][15]

Contraindication

Bictegravir should not be used with dofetilide and rifampin.[16] Use of dofetilide with bictegravir increases the concentration of dofetilide, which can lead to life-threatening events.[16] Concomitant use of bictegravir and rifampin causes significant interactions because of an effect rifampin has on bictegravir.[16] Bictagravir is metabolized primarily through the liver (CYP3A4), so inducers of CYP3A4 should be avoided.[4]

Adverse effects

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

Society and culture

Economics

In February 2022, Gilead agreed to pay ViiV Healthcare over $1 billion to settle patent infringement cases.[17][18]
