Active clinical trials for "HIV Infections"

The Radata-Fuzeon cohort is an observational cohort study to gain a better understanding of Fuzeon (Enfuvirtide) in daily clinical practice. Patients planned to take this drug in a new antiretroviral combination therapy (ART) are eligible to participate in this observation. Physicians may register patients online via the internet. They are offered to get an expert advice suggesting therapeutics for a new ART. Observation interval is every three month. However physicians are allowed to initiate new diagnostics, expert advice and therapeutic changes independently from these intervals if necessary. Total observation time for each patients is planned for two years.

The immune systems of some individuals may be capable of resisting HIV infection. These individuals do not appear to be infected with HIV despite multiple sexual encounters with HIV infected partners. This study will examine the immune systems of these individuals to determine what factors are responsible for their ability to resist HIV infection. Study hypothesis: Some long-term, multiply-exposed seronegative persons have relative resistance to HIV infection maintained by T cell responses.
