Intervention

Drug:
maraviroc
The nominal dose for maraviroc is 300 mg twice a day (BID). However, the dosage of maraviroc should be adjusted based on optimal background therapy (OBT) patient is taking. If OBT includes CYP3A4 inhibitor (with or without inducers) maraviroc dose should be 150 mg BID and if OBT includes CYP3A4 inducer (without inhibitors) maraviroc dose should be 600mg BID. If OBT does not include any CYP3A4 inducers or inhibitors maraviroc dose should be 300 mg BID.

Outcome

Type Measure Description Time frame Safety issue
Primary Percentage of Participants With Grade 3 and Grade 4 Adverse Events (AE) AEs as defined by the Division of AIDS (DAIDS) toxicity grading scale: Grade 3 = severe: interrupted usual daily activity and traditionally required systemic drug therapy or other treatment. Grade 4 = very severe: events that were unacceptable and intolerable or were irreversable or caused imminent danger of death. If same participant had more than 1 occurrence in the same preferred term event category, only the most severe (grade 4) occurrence was taken. Treatment-related = investigator assessment of a reasonable possibility that the investigational product caused or contributed to the AE. Baseline up to Week 144 Yes

Baseline up to Week 144 Yes
Primary Percentage of Participants With Grade 4 Laboratory Abnormalities Without Regards to Baseline Abnormalities Laboratory abnormalities as defined by the Division of AIDS (DAIDS) toxicity grading scale: Grade 4, Very Severe = events which were unacceptable and intolerable or were irreversible or caused the participant to be in imminent danger of death. Baseline up to Week 144 Yes
Primary Percentage of Participants With Acquired Immunodeficiency Syndrome (AIDS)-Defining Illnesses Treatment-emergent AIDS-defining opportunistic illnesses based on investigator classification guided by a predefined list of clinical Category C adverse events per Center for Disease Control (CDC) HIV Classification System.

Primary Percentage of Participants With Possible Acquired Immunodeficiency Syndrome (AIDS) Related Infections and Malignancies by Time on Therapy Baseline up to Week 144 Yes
Primary Percentage of Participants With All Causality Treatment-emergent Adverse (AEs) Events by Gender Treatment-emergent AEs by gender that occurred up to 30 days after the last dose of study medication. Baseline up to Week 144 Yes
Primary Percentage of Participants With Treatment-emergent Adverse Events (AEs) by Race Treatment-emergent AEs by race that occurred up to 30 days after the last dose of study medication. Baseline up to Week 144 Yes
Primary Percentage of Participants With Treatment-emergent Adverse Events (AEs) by Age Treatment-emergent AEs by age that occurred up to 30 days after the last dose of study medication. Baseline up to Week 144 Yes
Primary Percentage of Participants With Treatment-emergent Averse Events (AEs) by Baseline Hepatitis B and Hepatitis C Virus Serology Status Treatment emergent AEs by hepatis B and hepatitis C serology status that occurred up to 30 days post last dose. Baseline up to Week 144 Yes

Baseline value calculated as average of the screening and baseline values if both values were within 1 log10 difference.
Baseline up to Week 144 No
Secondary Percentage of Participants With =1.0 log10 Reduction From Baseline in HIV 1 RNA Defined as HIV-1 RNA levels < 400 copies/mL or at least 1.0 Log 10-decrease from baseline in HIV-1 RNA levels.

Secondary Percentage of Participants With HIV-1 RNA Levels Below the Limit of Quantification: <400 Copies/mL Limit of quantification defined as <400 copies/mL. Baseline value calculated as average of the screening and baseline values if both values were within 1 log 10 difference. Baseline up to Week 144 No
Secondary Percentage of Participants With HIV-1 RNA Levels Below the Limit of Quantification: <50 Copies/mL Limit of quantification defined as <50 copies/mL. Baseline value calculated as average of the screening and baseline values if both values were within 1 log 10 difference. Baseline up to Week 144 No
Secondary Change From Baseline in CD4 Cell Count Change from baseline in cluster of differentiation 4 helper T cells (CD4) cell count. If baseline value was not available, it was taken from immediate preceding non-missing value. Baseline up to Week 144 No
