A Prospective and Retrospective Observational Study of Multidrug-Resistant Patient Outcomes With and Without Ibalizumab
The virological efficacy of ibalizumab has been clearly demonstrated in multiple clinical trials. This study will expand ibalizumab's clinical data set and allow a better understanding of the virologic response durability on ARV regimens with or without ibalizumab in a heterogeneous real-world patient population. Additional data on the efficacy and …
Leukapheresis to Obtain Plasma or Lymphocytes for Studies of HIV-infected Patients, Including Long-term Non-progressors
This study will collect white blood cells and plasma for research on how the immune system controls HIV infection. The immune system of a very small group of HIV-infected patients, called non-progressors, has been able to control HIV for long periods without antiretroviral therapy. Some immune system-related genes important for …
