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.

This study will examine how marijuana use can affect oral bacteria and brain health in people with HIV and without HIV. Early studies show that marijuana users have more oral bacteria than non-marijuana users. The increase in bacteria is believed to affect brain health. Participation in the study will be one visit. The visit will take approximately 120 minutes.

This proposed project is to investigate the role of cocaine use in B cell dysfunctions and poor immune recovery from antiretroviral therapy in HIV.

This study is for Cisgender Men (CGM), Transgender Women (TGW), Transgender Men (TGM) & Gender Non-binary people (GNB) who have sex with male partners and who are at risk for HIV infection.

The study will test the experimental drug Lenacapavir (LEN) for the prevention of HIV infection, also known as Pre-Exposure Prophylaxis (PrEP). This study will also compare the effectiveness of LEN to Emtricitabine/Tenofovir Disoproxil Fumarate (F/TDF; Truvada®), which has already been approved in several countries for use as PrEP.

The COVID-19 pandemic has affected all persons, though disadvantaged populations such as persons living with HIV are likely to be disproportionally impacted by the physical, economic, and psychological toll of the global pandemic. This study aims to better understand how COVID-19 has impacted care for veterans living with HIV.

This study is to find the causes of treatment failure in some HIV patients. Thus, HIV-infected patients under antiretroviral treatment and uninfected healthy controls will be recruited in this study to donate blood, urine, saliva, and nasal swab. Compensation will be paid for you to participate in this study.

Human subjects are being recruited for the proposed study to participate in usability testing for a virtual reality technology tool to be refined for assessment and prevention of risky sexual and substance use behaviors. Specifically, 15 adolescents, 15 young men, and 15 front line health care providers will participate in qualitative interviews and focus groups. Targeted enrollment is based on estimates from the existing clinical population treated by the local clinics from which participants will be recruited and the candidate's experience conducting clinical studies at these sites.

The purpose of this study is to explore the use of a new treatment program to improve medication adherence for people with HIV and PTSD for patients at local HIV care clinics. Participants will be assigned to one of two groups. Participants in Group A will be asked to attend 12 clinic sessions (twice a week for 6 weeks, 90-minute sessions) via telehealth or in person at a HIV care clinic. Participants in Group B will receive a one session adherence intervention (60 minutes) and get the same standard treatment that someone with a trauma history and co-occurring HIV and PTSD symptoms would receive at a local HIV care clinic. The study is provided at no-cost, and participants may learn useful information and coping skills while being in the study. It is hoped the information that we get from this study will help researchers and clinicians better design treatment programs for people living with HIV and PTSD. Participants will receive study compensation for their time.

Many adolescents experience traumatic events, such as child abuse, physical or sexual assault, or witnessing violence. Teens who experience trauma are more likely to have problems with substance use and risky sexual activity. We want to understand how parents can support their teens and help keep them safe after traumatic events.
