  Purpose

The purpose of this study is to determine whether or not adding Raltegravir to a fully suppressive antiretroviral regimen will assist in reducing HIV-1 associated chronic inflammation and increase the t-lymphocyte memory cell pool.


Condition Intervention
Acquired Immunodeficiency Syndrome
 Drug: Raltegravir

Study Type: Interventional
Study Design: Endpoint Classification: Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Supportive Care
Official Title: A Pilot Study to Assess the Downregulation of HIV-1 Associated Chronic Inflammation in Patients With Limited Immunologic Responses When Raltegravir is Added to a Virologically Suppressed HAART Regimen

Further study details as provided by National Jewish Health:

Primary Outcome Measures:
  • Quantitative changes in activated CD4+/CD8+ T-lymphocytes, pro-inflammatory cytokines and the central memory cell pool [ Time Frame: 12 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Measure the change in circulating CD4+ and CD8+ T-lymphocytes [ Time Frame: 12 months ] [ Designated as safety issue: No ]
  • Determine whether the circulating CD8+ T-lymphocyte count or the CD4+/CD8+ ratio can serve as a surrogate marker for suppression of chronic inflammation [ Time Frame: 12 months ] [ Designated as safety issue: No ]
