Comparison of Virologic & Immunologic Responses to Raltegravir &

Status Completed

Clinical Trial Summary

This is a Phase IV, open label, observational study to compare the gastrointestinal tissue concentrations, inflammatory response, and viral replication of two integrase-inhibitors, raltegravir and dolutegravir, in HIV-infected volunteers who are virologically suppressed in blood plasma. The study will be comprised of 20 HIV-infected volunteers who will be enrolled equally into two groups. Group A will consist of 10 subjects receiving an antiretroviral regimen of tenofovir, emtricitabine, and raltegravir, and Group B will consist of 10 subjects receiving an antiretroviral regimen of tenofovir, emtricitabine, and dolutegravir. Participants will provide small pieces of tissue, or biopsies, which will be taken from three distinct locations of the large intestine during a colonoscopy procedure. These biopsies will be used to measure the amount of raltegravir or dolutegravir, HIV virus, and inflammatory markers present in the gastrointestinal tract.

Clinical Trial Description

Purpose: To compare virologic and immunologic responses to raltegravir and dolutegravir in the gastrointestinal tract of HIV-positive men and women

Participants: Twenty HIV-infected volunteers will be enrolled equally into two groups. Group A will consist of subjects receiving an antiretroviral regimen of raltegravir, tenofovir, and emtricitabine and Group B will consist of subjects receiving an antiretroviral regimen of dolutegravir, tenofovir, and emtricitabine.

Procedures (methods): This is a Phase IV, open label study to compare the gastrointestinal tissue concentrations, cytokine response, and viral replication in gut-associated lymphoid tissue of two integrase-inhibitors in HIV-infected volunteers who are virologically suppressed in blood plasma. Subjects will undergo an observed bowel preparation, followed by a colonoscopy in which tissue will be obtained by a board-certified gastroenterologist from the terminal ileum/ascending colon, splenic flexture, and rectum/sigmoid colon. Blood plasma will be collected immediately prior to collection of tissue samples. ;

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.
