Summary

This trial will compare the effectiveness of two different drug combinations for treating HIV and hepatitis B in adults who have not previously received treatment for either virus.

Who is the study for?
This trial is for adults who have both HIV-1 and Hepatitis B but haven't started treatment yet. They need a certain level of HIV in their blood and must be sensitive to specific drugs. People with severe liver issues, high levels of HBV DNA, recent serious infections, or those using substances that could affect the study can't join.
What is being tested?
The study compares two treatments for HIV-1 and Hepatitis B co-infection: one group receives a combo pill (B/F/TAF), while the other gets Dolutegravir plus another combo (F/TDF). The goal is to see which treatment works better for people who are new to HIV therapy.
What are the potential side effects?
Possible side effects include digestive problems, headaches, fatigue, skin reactions, and changes in liver enzymes. There might also be risks related to drug interactions between medications used for treating HIV and Hepatitis B.

Trial Design

3Treatment groups
Experimental Treatment
Active Control
Group I: Open-label Extension Phase: B/F/TAFExperimental Treatment1 Intervention
After Week 96, participants will continue to take their blinded study drug and attend visits every 12 weeks until the End of Blinded Treatment Visit. Following the End of Blinded Treatment Visit, participants in a country where B/F/TAF FDC is not available will be given the option to receive B/F/TAF FDC in an open-label extension phase for up to 48 weeks, or until the product becomes accessible through an access program, or until Gilead elects to discontinue the study in that country, whichever occurs first.
Group II: B/F/TAFExperimental Treatment3 Interventions
B/F/TAF + placebo to match DTG + placebo to match F/TDF for 96 weeks.
Group III: DTG+F/TDFActive Control3 Interventions
DTG + F/TDF + placebo to match B/F/TAF for 96 weeks.
