A study about long-term medical problems experienced by people who recover from COVID-19 and whether people who recover develop long-term immunity to SARS-CoV-2, the virus that causes COVID-19.
People infected with HIV take drugs called antiretrovirals to keep the amount of HIV in their bodies low as well as anticoagulants to treat or prevent blood clots. This study will help gain a better understanding of how antiretrovirals and oral anticoagulants interact with each other.
This study will evaluate the preventive vaccine efficacy, safety, and tolerability of the ALVAC-HIV vaccine + Bivalent Subtype C gp120 protein adjuvanted with MF59 in HIV-seronegative South African adults over 24 months from enrollment.
We plan to test the once weekly TB treatment together with different anti-HIV drugs in HIV-negative healthy people. We will study these combinations in up to three different groups of study participants.
This study will evaluate the safety and efficacy of the injectable drug cabotegravir (CAB LA), for pre-exposure prophylaxis (PrEP) in HIV-uninfected cisgender men and transgender women who have sex with men (MSM and TGW).
The purpose of the study is to test HIV vaccines to see if they are safe. It is not possible to get HIV through participating in the study. Vaccines are used to create resistance to a disease, or to prevent infection. The study vaccines will use a live adenovirus, the type of virus that typically causes cold symptoms. We hope that this adenovirus will help to stimulate an immune response against HIV.
In this study, we will look at whether rifapentine and isoniazid affect blood levels of a commonly used antiretroviral called tenofovir alafenamide, or TAF. The United States Food and Drug Administration (FDA) has approved rifapentine and isoniazid for treating TB.
