The main objective of this study is to test a once-weekly HIV medication regimen in persons who have not taken HIV treatment before. The goal is to see if taking a once a week pill combination (GS-1720 and GS-4182) works as well as taking a daily pill Biktarvy® (B/F/TAF). Participants will either take the weekly pill or continue with Biktarvy® for about 48 weeks or longer. The study will look at how well each option controls HIV levels.

This study is to understand HIV-infected cocaine users have poor immunity after anti-HIV treatment, but HIV-infected cannabis users are likely different. Cocaine use always is associated high inflammation and cannabis use is associated with low inflammation. We study how inflammation cannot be controlled in cocaine users; our goal is to develop new therapies to help cocaine users to have a better health and immunity.

This is a cross-sectional survey in persons with HIV infection to evaluate experiences of historical oral therapy use and how their perceptions on treatment may have changed with the availability of injectable long-acting therapy. In
addition to surveys, a corresponding retrospective medical chart review will be conducted for each participant.

HIV infected cocaine users have uncontrolled viral levels and impaired immunity to control infection compared to HIV infected non-drug users. We ask the questions why cocaine use makes HIV infected cocaine users more sick than other patients. The goal is to improve immunity to control HIV infection in cocaine users. Both uninfected cocaine users and HIV-infected cocaine users are especially needed in this study.

The primary objective of this study is to determine how bictegravir (BIC) plus lenacapvir (LEN) in two different doses affects an HIV-1 infection in the body compared with current standard treatment regimens. Other objectives are to determine which of these treatments are the most effective for treating HIV-1 infection, the safety and tolerability of these two doses for people with HIV, as well as how long it stays in the body using physical exams, laboratory tests, ECG, blood analysis, and any symptoms or problems experienced during the study.
