Time-Weighted Average Change From Baseline up to Day 11 (DAVG11) in Plasma HIV-1 RNA
Baseline up to Day 11

DAVG11 was defined as the time-weighted average between the first postbaseline value through the last available on-treatment (ie, the last dose date + 1) value up to Day 11 minus the baseline value in plasma HIV-1 RNA (log10 copies/mL). All HIV-1 RNA data up to Day 11 were used for this analysis. DAVG11 was calculated using the trapezoidal rule and the area-under-the-curve concept.

Frequently asked questions about Bictegravir

What is Bictegravir used for?

Bictegravir is an investigational small molecule being developed for the treatment of HIV, specifically HIV-1 infection. It is studied in combination with other antiretroviral agents, including emtricitabine and tenofovir alafenamide, as well as lenacapavir, for managing HIV-1 in infected adults.

What does Bictegravir target?

Bictegravir is an integrase strand transfer inhibitor that targets the HIV-1 integrase enzyme, blocking viral DNA integration into host cells. This mechanism disrupts the HIV replication cycle, reducing viral load in infected individuals.

Who makes Bictegravir?

Bictegravir is developed by Gilead Sciences, Inc., a biopharmaceutical company traded on NASDAQ under the ticker GILD. Gilead is conducting clinical trials to evaluate the drug's safety and efficacy in treating HIV-1 infection.

What phase is Bictegravir in?

Bictegravir is in Phase 1 clinical development, with early studies assessing safety, pharmacokinetics, and antiviral activity. It remains investigational and has not been approved by regulatory authorities for commercial use.

What clinical trials is Bictegravir in?

Bictegravir is being studied in several trials, including NCT02275065, a completed Phase 1 study evaluating safety and antiviral activity in HIV-1 infected participants, and NCT02400307, a completed pharmacokinetic study in adults with normal and impaired renal function. Additional trials are ongoing.

Is Bictegravir the same as Bictegravir/emtricitabine/tenofovir alafenamide?

Bictegravir is a component of the combination product bictegravir/emtricitabine/tenofovir alafenamide, which is also known as Biktarvy. While bictegravir alone is the active integrase inhibitor, the combination includes two additional antiretroviral drugs for enhanced efficacy.
