What You Need to Know Before You Apply

What is the purpose of this trial?

The goal of this clinical study is to learn more about the effects of switching to the study drugs, bictegravir (BIC)/lenacapavir (LEN), fixed-dose combination (FDC) versus current therapy bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) FDC in people living with HIV-1 (PWH). The primary objective of this study is to learn how effective it is to switch to BIC/LEN FDC tablets versus continuing on B/F/TAF FDC tablets in virologically suppressed PWH.

Do I have to stop taking my current medications for this trial?

The trial requires participants to switch from their current B/F/TAF medication to the study drugs BIC/LEN. If you are on B/F/TAF, you will need to stop taking it to participate in the trial.

Will I have to stop taking my current medications?

The trial requires participants to switch from their current B/F/TAF medication to the study drugs BIC/LEN. If you are taking other medications, the protocol does not specify if you need to stop them, but you should discuss this with the study team.

What safety data exists for Bictegravir and Lenacapavir in HIV treatment?

Bictegravir (BIC), a component of Biktarvy, has been shown to be well-tolerated with main adverse effects including diarrhea, nausea, and headache. Real-world studies indicate higher adverse effects and discontinuation rates compared to clinical trials. BIC has a high genetic barrier to resistance and limited drug-drug interactions. Lenacapavir, marketed as Sunlenca, is not specifically mentioned in the provided research, so its safety data is not covered here. ^{1 2 3 4 5}

What safety data exists for Bictegravir and Lenacapavir in humans?

Bictegravir, a component of Biktarvy, is generally well tolerated in humans, with common side effects including diarrhea, nausea, and headache. Real-world studies have shown higher rates of adverse effects and discontinuation compared to clinical trials, but it is considered safe with limited drug interactions. There is no specific safety data for Lenacapavir in the provided research articles. ^{1 2 3 4 5}

Is the drug Bictegravir, Lenacapavir a promising treatment for HIV?

Yes, Bictegravir, Lenacapavir is a promising drug for HIV because it is part of a single-tablet regimen that is safe, effective, and easy to take. It helps improve the lives of people with HIV by addressing other health issues they might face, like heart disease or bone problems, and has a strong ability to fight the virus without developing resistance. ^{6 7 8 9 10}

What makes the drug Bictegravir + Lenacapavir unique for treating HIV?

Bictegravir + Lenacapavir is unique because it combines a novel integrase strand transfer inhibitor (Bictegravir) with a long-acting formulation (Lenacapavir), potentially allowing for less frequent dosing compared to standard daily regimens. This combination aims to improve adherence and reduce the risk of drug resistance, offering a new approach to HIV treatment. ^{1 2 3 4 11}

What data supports the idea that Bictegravir + Lenacapavir for HIV is an effective drug?

The available research does not provide any data on Bictegravir + Lenacapavir for HIV. Instead, it focuses on treatments for advanced biliary tract cancer, so there is no information here to support the effectiveness of Bictegravir + Lenacapavir for HIV. ^{9 10 12 13 14}
