  • Background: Treatment of Human Immunodeficiency Virus (HIV) requires a combination of multiple antiretroviral medications to prevent viral replication. Most HIV patients prefer to be on a “once daily” treatment. Maraviroc (Selzentry®), is currently administered twice daily. Studies have been conducted to evaluate the efficacy of Maraviroc if given once daily; however, not in virologically suppressed patients. There is an advantage to a once daily regimen from an adherence prospective; hence, the need to assess the virologic and immunologic efficacy, also the tolerability and potential toxicity of two tablets of Maraviroc once daily.

    Methods: CCR5 tropic HIV positive patients with undetectable viral load, on regimens including a Protease Inhibitor,Non-Nucleoside Reverse Transcriptase Inhibitor or an Integrase Inhibitor in addition to two Nucleoside Reverse Transcriptase Inhibitors. The patients were switched to once daily Maraviroc (2 pills/600mg) in combination with two NRTI’s and were followed for 48 weeks. Assessing Virologic and immunologic efficacy at weeks 24 and 48.

    Results: 34 patients were screened. Week 48 Interim analysis on 28 patients showed high regimen tolerance, virologic and immunologic efficacy with minimal or no side effects and no serious adverse events. Treatment satisfaction questionnaires showed an overall increased satisfaction with once daily Maraviroc regimen.

    Conclusion: Maraviroc administered once daily (2 pills/600 mg) proved to be safe and effective. Demonstrated positive impact on patients’ adherence to treatment regimen.
