The Role of the Gastrointestinal-associated Lymphoid Tissue in the Cure of HIV Infection
What this study is about
The objective of this study is to understand the effects of HIV cure strategies on the virus and immune cells that reside within the gastrointestinal tract. Subjects receiving therapies with the potential for HIV cure will undergo a colonoscopy to obtain gastrointestinal tissue for research assays.
View original scientific description
The objective of this study is to understand the effects of HIV cure strategies on the virus and immune cells that reside within the gastrointestinal tract. Subjects receiving therapies with the potential for HIV cure will undergo a colonoscopy to obtain gastrointestinal tissue for research assays. This study will test whether receiving these therapies will induce changes in the immune cells in the gastrointestinal tract and reduce the tissue-associated HIV viral levels.
Interventions
PROCEDURE
Colonoscopy
Colonoscopy is a procedure where an instrument called colonoscope is inserted through the rectum to look at the entire internal surface of the intestine. Participants will be placed on a stretcher on the left side. A colonoscope will be advanced into the colon and into the terminal ileum. The entire procedure should take approximately 40 minutes
Primary outcome measures
Change in HIV tissue viral load
Time frame: End of the study (at month one) compared to baseline
Change in HIV in tissue-associated HIV RNA viral load at the end of the study at month one compared to baseline
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
