Can a blood bank unlock the secrets of HIV control?
NCT ID NCT00187512
First seen Sep 08, 2026 · Last updated Sep 09, 2026 · Updated 1 time
Summary
This observational study enrolls 2,500 people with HIV to build a detailed bank of blood samples and health records. Researchers will use these specimens to investigate how the virus behaves, why some people progress slowly or control the virus without medication, and how antiretroviral therapy affects long-term outcomes. The study does not test a new drug; it gathers data to answer multiple questions about HIV infection, immune response, and drug resistance.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- This study could help researchers understand why some people with HIV control the virus without drugs, and how treatments affect long-term health.
- What could go wrong
- As an observational study, it does not test a new treatment, so it cannot directly lead to a cure or therapy. Findings may take years to translate into clinical practice.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: SCOPE is currently recruiting HIV-1 infected subjects with any of the following criteria: 1. Documented HIV viral load less than 2000 copies/ml WITHOUT taking antiretroviral therapy 2. Undetectable HIV viral load with CD4 T-cells consistently less than 350 for the last 12 months while taking a stable antiretroviral regimen. 3. Antiretroviral naive and planning to start an antiretroviral regimen - any CD4 or HIV viral load acceptable. 4. Long-term Non Progressors: HIV-positive at least 10 years, no antiretroviral therapy for the past 10 years or more, any viral load acceptable, CD4-T cell count always above 500. Exclusion Criteria: 1. Active opportunistic infection or systemic treatment for opportunistic infection within the last 4 months (oral candidiasis acceptable) 2. Active treatment for cancer 3. Active treatment for hepatitis C requiring interferon based therapy 4. Immunosuppressive therapy taken within the last 4 months
