NCT00709111

Brief Summary

Despite viral suppression, antiretroviral therapy (ART) does not restore CD4+ T-cell counts in some subjects. The purpose of this study is to assess whether adding maraviroc (MVC) to a suppressive ART will result in a significant CD4+ T-cell count increase over 24 weeks in subjects with suboptimal CD4+ T-cell recovery despite sustained virologic suppression.

Outcome Measures

Primary Outcomes (1)

  • Change in CD4+ T-cell Count

    Change was calculated as the week 24 CD4+ T-cell count (average of the week 22 and week 24 values) minus the baseline CD4+ T-cell count (average of pre-entry and entry values).

    From baseline to week 24

Secondary Outcomes (34)

  • Proportion of Participants Achieving a 50-cell Increase in CD4+ T-cell Count

    From baseline to week 24

  • Within-subject CD4+ T-cell Count Slopes

    From baseline through week 24

  • Change From Within-subject Pre-treatment CD4+ T-cell Count Slopes to Corresponding Within-subject CD4+ T-cell Count Slopes From Baseline Through Week 24

    From pre-treatment through week 24

  • Change in CD4+ T-cell Count

    From week 24 to week 36

  • Change in CD4+ T-cell Count

    From week 24 to week 48

  • +29 more secondary outcomes

Study Arms (1)

Maraviroc

EXPERIMENTAL

Maraviroc (MVC) was taken for 24 weeks, in addition to the subject's current antiretroviral therapy (ART) drug regimen. At week 24, subjects discontinued MVC and were followed for an additional 24 weeks off MVC, but still on current ART drug regimen.

Drug: Maraviroc

Interventions

The maraviroc doses were 150 mg orally twice daily, 300 mg orally twice daily, or 600 mg orally twice daily, depending on the pharmacokinetic interaction with a subject's pre-study ART and non-ART drug regimen according to the package insert.

Also known as: MVC, Selzentry
Maraviroc

  • An acute AIDS-defining illness within 60 days prior to study entry
  • Known allergy/sensitivity or hypersensitivity to components of MVC, including allergy or hypersensitivity to soya lecithin, soya or peanuts
  • Active drug or alcohol abuse that, in the opinion of the investigator, would interfere with adherence to study regimens
  • Serious illness requiring systemic treatment and/or hospitalization within 60 days prior to study entry
  • Receipt of a vaccine within 30 days prior to study entry
  • Current or previous use of a CCR5 inhibitor
  • Plan to change background ART regimen within 24 weeks after study entry
