The Role of the Gastrointestinal-associated Lymphoid Tissue in the Cure of

Status Enrolling by invitation

Clinical Trial Summary

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.

Clinical Trial Description

After almost forty years from its first discovery, Human Immunodeficiency Virus (HIV) infection remains uncurable. The major obstacle to a cure for HIV infection is the integration of HIV into the host genome and its persistence in populations of long-lived immune cells subsets. These long-lived resting cells represent a reservoir of transcriptionally silent HIV and they are mostly localized in the secondary lymphoid tissue and the gastrointestinal associated lymphoid tissue (GALT). The most promising HIV cure strategies relay on molecules which can induce enhanced immune responses through antibody mediated effects such as antibody-dependent cellular cytotoxicity (ADCC) and phagocytosis (ADCP) as well as enhanced CD8+ T cells activity. The specific purpose of this study is to evaluate whether the proposed treatment strategies for HIV cure, can induce changes in the gastrointestinal associated immune system (GALT) effector immune cells such as NK cells, cytotoxic CD8+ T Cells and whether treatment with these molecules leads to changes in the amount of tissue-associated HIV virus within the GALT. The results from the proposed study will inform on the ability of these molecules to exert their effect on this critical site of HIV latency and persistence and thus advance the field on their HIV cure potential. Subjects receiving treatment with the potential for HIV cure will undergo a colonoscopy to obtain gastrointestinal tissue for research assays. The research proposal will test the hypothesis of whether these molecules are able to induce changes in the immune cells in the gastrointestinal tract and reduce the tissue-associated HIV viral levels. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
