Target Recruitment
209
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.

Primary Outcome Measures
NameTimeMethod
Number of Participants With Grade 3 and Grade 4 Adverse Events (AEs) and Serious Adverse Events (SAEs)Baseline to 30 days post-week 96 or early termination (ET)

AEs: any untoward medical occurrence/worsening of pre-existing medical condition, whether or not related to study drug. SAE: any AE that resulted in death; was life threatening; resulted in persistent/significant disability/incapacity; resulted in/prolonged an existing in-patient hospitalization; was congenital anomaly. Grade 3: Events that interrupted participant's usual daily activity and traditionally required systemic drug therapy or other treatment. Grade 4: Events which were unacceptable and intolerable or which were irreversible or caused participant to be in imminent danger of death.

Number of Participants With Division of Acquired Immunodeficiency Syndrome (DAIDS) Grade 3 and Grade 4 Laboratory AbnormalitiesBaseline to 30 days post-week 96 or ET

Grade 3 or severe events included those that interrupted participant's usual daily activity and traditionally required systemic drug therapy or other treatment. Grade 4 or very severe events included those that were unacceptable and intolerable or which were irreversible or caused the participant to be in imminent danger of death.

Number of Participants With Treatment Emergent MalignanciesBaseline to 30 days post-week 96 or ET
Number of Participants With Category C Acquired Immunodeficiency Syndrome (AIDS) Related InfectionsBaseline to 30 days post-week 96 or ET

Number of participants with AIDS-related infections based on investigator classification guided by a predefined list of clinical Category C AEs per Center for Disease Control (CDC) HIV Classification System.

Number of Participants With Laboratory Test AbnormalitiesBaseline to 30 days post-week 96 or ET

Pre-defined criteria based on upper limit normal (ULN) and lower limit normal (LLN) were established for each laboratory test to define the values that would be identified as laboratory test abnormality.

Below limit of quantification was defined as less than 400 copies/milliliter (mL)
