What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores how a combination of three medications—Bictegravir, Emtricitabine, and Tenofovir Alafenamide—works in the body and assesses its safety for children and teens living with HIV-1. The study aims to determine the best dose and evaluate how well the treatment is tolerated. Suitable candidates for this trial include children or teens who have lived with HIV-1 and maintained a stable treatment routine for at least six months, meeting specific weight and age criteria. As a Phase 2, Phase 3 trial, this study measures the treatment's effectiveness in an initial group and represents the final step before FDA approval, offering participants a chance to contribute to significant advancements in HIV-1 treatment.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop your current medications, but it mentions that participants should be on a stable antiretroviral regimen for at least 6 months before joining. If you are taking nevirapine or efavirenz, you should have stopped at least 14 days before enrolling.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research shows that the combination of Bictegravir, Emtricitabine, and Tenofovir Alafenamide (B/F/TAF) is generally safe for people with HIV. Studies have found that this treatment is well-tolerated over 48 weeks, with most patients not experiencing severe side effects. In one study, 93.8% of patients achieved successful results, reducing their HIV levels to very low levels.

Another study confirmed its effectiveness and safety over 12 months, with no major health issues reported. B/F/TAF is already used for adults with HIV, providing some confidence in its safety. However, like any treatment, some side effects may occur, but serious problems are rare. Always consult a doctor about any concerns or questions. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for HIV?

Unlike the standard HIV treatments, which typically involve multiple pills, the B/F/TAF combination offers a single-tablet regimen. This combination includes Bictegravir, which is a newer integrase inhibitor, along with Emtricitabine and Tenofovir Alafenamide. Bictegravir is known for its strong potency and high barrier to resistance, making it a standout choice. Researchers are excited about this treatment because it simplifies the daily regimen for patients and has a favorable side effect profile, potentially improving adherence and overall patient outcomes.

What evidence suggests that this treatment might be an effective treatment for HIV?

Research has shown that the combination of Bictegravir, Emtricitabine, and Tenofovir Alafenamide (B/F/TAF) effectively treats HIV. In one study, 92% of participants with HIV showed positive results after 12 months of treatment. Another study found that almost all participants had their HIV levels in the blood under control after 24 weeks. Additionally, this treatment is generally well-tolerated, with few side effects reported. Overall, B/F/TAF offers a strong option for effectively managing HIV. Participants in this trial will receive B/F/TAF in various dosages based on age and weight, as part of different study cohorts. ^{2 5 6 7 8}

What Are the Treatments Tested in This Trial?

Interventions

• Bictegravir/Emtricitabine/Tenofovir Alafenamide Fixed Dose Combination

Trial Overview

The study tests various doses of Bictegravir/Emtricitabine/Tenofovir Alafenamide (B/F/TAF) in fixed dose combinations for safety and how the body processes them. The goal is also to confirm the appropriate dosing for these age groups while monitoring their response to this combination therapy.

How Is the Trial Designed?

Group I: Open-Label Extension Experimental Treatment 3 Interventions

Following Week 48, participants in countries where B/F/TAF is not available may have the option to receive adult strength B/F/TAF FDC, low dose B/F/TAF FDC, or B/F/TAF FDC TOS (based on age and weight) until it becomes available for use according to the participant's age and weight or the product becomes accessible to participants through an access program.

Group II: Cohort 4 Group 4 (≥ 1 month of age and weight ≥ 3 to < 6 kg) Experimental Treatment 1 Intervention

Participants will participate in an Intensive PK evaluation at Week 2 after which they will continue to receive B/F/TAF FDC TOS twice daily through Week 48.

Group III: Cohort 4 Group 3 (≥ 1 month of age and weight ≥ 6 to < 10 kg) Experimental Treatment 1 Intervention

Participants will participate in an Intensive PK evaluation at Week 2 after which they will continue to receive B/F/TAF FDC TOS twice daily through Week 48.

Group IV: Cohort 4 Group 2 (≥ 1 month of age and weight ≥ 10 to < 14 kg) Experimental Treatment 1 Intervention

Participants will participate in an Intensive PK evaluation at Week 2 after which they will continue to receive B/F/TAF FDC TOS twice daily through Week 48.

Group V: Cohort 4 Group 1 (≥ 2 years of age and weight ≥ 14 to < 25 kg) Experimental Treatment 1 Intervention

Due to Cohort 3 Part A Intensive PK evaluation at Week 2 with the low dose B/F/TAF FDC tablet, participants will not participate in an Intensive PK evaluation at Week 2. Participants will receive B/F/TAF FDC tablets for oral suspension (TOS) once daily through Week 48.

Group VI: Cohort 3 (≥ 2 years of age and weight ≥ 14 to < 25 kg) Experimental Treatment 1 Intervention

* Part A: Participants will participate in an Intensive PK evaluation at Week 2 after which they will continue to receive the low dose B/F/TAF FDC tablet through Week 48. * Part B: Following confirmation of BIC PK data from Cohort 3 Part A, participants will receive the low dose B/F/TAF FDC tablet through Week 48.

Group VII: Cohort 2 (6 to < 12 years of age and weight ≥ 25 kg) Experimental Treatment 1 Intervention

* Part A: Participants will participate in an Intensive PK evaluation at Week 2 or Week 4 and continue to receive the adult strength B/F/TAF FDC through Week 48. * Part B: Following confirmation of BIC PK data from Cohort 2 Part A, participants will receive the adult strength B/F/TAF FDC through Week 48.

Group VIII: Cohort 1 (12 to < 18 years of age and weight ≥ 35 kg) Experimental Treatment 1 Intervention

* Part A: Participants will participate in an Intensive PK evaluation at Week 2 or Week 4 and continue to receive the adult strength B/F/TAF FDC through Week 48. * Part B: Following confirmation of BIC PK data from Cohort 1 Part A, participants will receive the adult strength B/F/TAF through Week 48.

Published Research Related to This Trial

In a study involving 631 treatment-naive adults with HIV-1, the fixed-dose combination of bictegravir, emtricitabine, and tenofovir alafenamide was found to be non-inferior to the combination of dolutegravir, abacavir, and lamivudine at week 96, with 88% of participants achieving undetectable HIV-1 RNA levels.

Bictegravir was associated with fewer adverse events compared to dolutegravir, with only 28% of participants reporting drug-related side effects, and no participants discontinuing treatment due to adverse events, highlighting its safety and tolerability.

In a 48-week study involving 86 older adults with HIV, switching to the medication bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) resulted in a high rate of virologic suppression, with 90.7% of participants maintaining HIV-1 RNA levels below 50 copies/ml.

The treatment was well tolerated, with no serious adverse events related to the drug and a high adherence rate of 98.6%, indicating that B/F/TAF is a safe and effective option for older adults living with HIV.
