A short list of all the Observational studies on this page.


A5001

ACTG 5001 ALLRT stands for Adult AIDS Clinical Trials Group Longitudinal Linked Randomized Trials. It is a protocol designed to establish a group of patients who will be followed over approximately 5 years. ALLRT will study clinical outcomes as well as collect information about the immune system through laboratory tests, dosing information, quality of life measurements, and other measures. ALLRT is different from other protocols, because it follows you both on and between other ACTG studies, and ALLRT "pools" information across studies to answer its research questions. No medications are provided directly through this study.

Inclusion Criteria:

  • HIV positive and at least 13 years of age.
  • Enrolled in an approved ACTG study or just finished with an approved ACTG study.
  • Willing to be followed for at least 4 years.
  • Willing to have additional blood drawn if your other study does not provide all the necessary samples or you are between studies.
  • Willing to allow the ALLRT study team to access information from your other studies.
  • Willing and able to come for study visits 3 times per year even when not on another study.
