ClinicalTrials.gov Identifier: NCT00478231
  Purpose

To collect safety and tolerability data in a more diverse patient population of patients with HIV/Aids, who have limited therapeutic options.

Acquired Immunodeficiency Syndrome
HIV Infection
Drug: Maraviroc
Phase III

Study Type: Interventional
Study Design: Treatment, Non-Randomized, Open Label, Single Group Assignment, Safety Study
Official Title: A Multicenter, Open Label, Non-Comparative Safety Study Of Maraviroc

Further study details as provided by Pfizer:

Primary Outcome Measures:
  • Primary endpoint of this study is to collect safety information in all subjects who receive at least one dose of study medication in all study visits (involving clinical and laboratorial data). [ Time Frame: 96 weeks ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Change in chemokine co-receptor tropism from screening to time of virologic failure will be reported for all subjects meeting the definition of virologic failure. [ Time Frame: 96 weeks ] [ Designated as safety issue: No ]
  • Secondary endpoints include the following efficacy variables: change in HIV-1 RNA levels from baseline, proportion of subjects achieving HIV-1 RNA levels below the limit of quantification, CD4 and CD8 cell counts and percent [ Time Frame: 96 weeks ] [ Designated as safety issue: No ]
  • Time to virologic failure, and evolution of resistance to OBT in samples collected at time of virologic failure. [ Time Frame: 96 weeks ] [ Designated as safety issue: No ]

Estimated Enrollment: 200
Study Start Date: July 2007
Estimated Study Completion Date: July 2010
Estimated Primary Completion Date: July 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
1: Experimental Drug: Maraviroc

Maraviroc should be dosed BID with total dose adjusted according to the other drugs the patient is taking. Maraviroc may be taken with or without food.

The subject should only take missed doses if it is not within 6 hours prior to the planned next dose. No dose adjustment of OBT is required due to the presence of maraviroc.


  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Subjects with limited or no approved treatment options available to them due to resistance or intolerance;
  • Subjects must be failing to achieve adequate virologic suppression on their current regimen and have HIV-1 RNA ≥ 1000 copies/ml, at screening.
  • Have only R5 HIV-1 at Screening as verified by the Monogram Biosciences Trofile assay.

Exclusion Criteria:

  • Failed prior treatment with any CCR5 antagonist, in any ongoing CCR5 trials or having previously discontinued Maraviroc in trials
  • Potentially life threatening (Grade 4) laboratory abnormality or medical condition (according to the Division of AIDS table for grading severity of adult adverse experiences) still under investigation unless a diagnosis has been established and felt not to affect risk/benefit assessment or eventual interpretation of safety results, based on discussion between the investigator and Pfizer.
