Trial of Maraviroc (UK-427,857) in Combination With Optimized Background Therapy Versus Optimized Background Therapy Alone for the Treatment of HIV-1 Infected Subjects (MOTIVATE 2)

A Multicenter, Randomized, Double-Blind, Placebo-Controlled Trial of a Novel CCR5 Antagonist, UK-427,857, in Combination With Optimized Background Therapy Versus Optimized Background Therapy Alone for the Treatment of Antiretroviral-Experienced HIV-1 Infected Subjects

Maraviroc (UK-427,857), a selective and reversible CCR5 coreceptor antagonist, has been shown to be active in vitro against a wide range of clinical isolates (including those resistant to existing classes). In HIV-1 infected patients, maraviroc (UK-427,857) given as monotherapy for 10 days reduced HIV-1 viral load by up to 1.6 log, consistent with currently available agents. Safety and toleration have been studied in over 400 subjects for up to 28 days at 300 mg twice daily. No significant effects were seen on the QTc interval. The purpose of this study is to evaluate the antiretroviral activity of maraviroc (UK-427,857) in HIV infected, treatment experienced patients who are failing their current antiretroviral regimen and infected with R5-tropic virus exclusively. This study will involve more than 100 centers in Europe and Australia to achieve a total randomized subject population of 500 subjects. Patients will be randomly (2:2:1) assigned to one of three groups: Optimized Background Therapy [OBT (3-6 drugs based on treatment history and resistance testing)] + maraviroc (UK-427,857) 150 mg taken once daily, OBT + maraviroc (UK-427,857) 150 mg taken twice daily, or OBT alone. The study will enroll over approximately a 9 month period with 48 weeks of treatment. This may be extended for an additional year depending on the results at 48 weeks. Physical examinations will be performed at study entry, weeks 4, 8, 12, 16, 20, 24, 32, 40 and 48. Blood samples will also be taken at study entry, weeks 2, 4, 8, 12, 16, 20, 24, 32, 40 and 48. Additionally, blood samples will be drawn twice, at least 30 minutes apart, at weeks 2 and 24 for maraviroc (UK-427,857) pharmacokinetic analysis. As part of this clinical study a blood sample will also be taken for non-anonymized pharmacogenetic analysis. Patients will undergo a 12-lead electrocardiogram at study entry, weeks 24 and 48.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Log 10-transformed Human Immunodeficiency Virus Ribonucleic Acid (HIV-1 RNA) Levels at Baseline	Baseline value calculated as average of pre-dose measurements collected at screening, randomization, and immediately pre-dose.	Baseline
Change From Baseline in Log 10-transformed HIV-1 RNA Levels at Week 24	Change from baseline in log 10-transformed plasma viral load (HIV-1 RNA) levels (log10 copies/mL). Baseline value calculated as average of pre-dose measurements collected at screening, randomization, and immediately pre-dose.	Baseline and Week 24
Change From Baseline in Log 10-transformed HIV-1 RNA Levels at Week 48	Change from baseline in log 10-transformed plasma viral load (HIV-1 RNA) levels (log10 copies/mL). Baseline value calculated as average of pre-dose measurements collected at screening, randomization, and immediately pre-dose.	Baseline and Week 48

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Percentage of Participants With HIV-1 RNA Levels Less Than 400 Copies/mL		Week 24 and 48
Percentage of Participants With HIV-1 RNA Levels Less Than 50 Copies/mL		Week 24 and 48
Cluster of Differentiation 4 (CD4) and Cluster of Differentiation 8 (CD8) Cell Count at Baseline	Baseline value calculated as average of pre-dose measurements collected at screening and immediately pre-dose.	Baseline
Time-Averaged Difference (TAD) From Baseline in log10 Transformed HIV-1 RNA Levels	TAD from baseline was calculated as area under the curve of HIV-1 RNA load (log10 copies/mL) divided by time period minus baseline HIV-1 RNA load (log10 copies/mL). Baseline value calculated as the average of pre-dose measurements collected at screening, randomization, and immediately pre-dose.	Baseline to Week 24 and Week 48
Change From Baseline in Viral Load at Week 24 and Week 48 by Overall Susceptibility Score (OSS) at Screening	Association between baseline resistance and virological response was assessed as change in viral load by OSS at screening. OSS categorized as 0, 1, 2, >3 (maximum value of 6) and calculated as the sum of the net assessment of in-vitro phenotypic and genotypic susceptibility using a binary scoring system (0= resistant, 1= sensitive or susceptible) for each antiretroviral agent in OBT. Higher scores indicate greater susceptibility. Baseline value is the average of the values from screening, randomization and immediately pre-dose.	Baseline, Week 24 and Week 48
Percentage of Participants With HIV-1 RNA Levels Less Than 400 Copies/ml or With at Least 0.5 log10 Decrease From Baseline		Week 24 and 48
Percentage of Participants With HIV-1 RNA Levels Less Than 400 Copies/ml or With at Least 1.0 log10 Decrease From Baseline		Week 24 and 48
Change From Baseline in CD4 Cell Count at Week 24 and 48	Change from baseline in CD4 cell count measured as cells/µL. Baseline value calculated as average of pre-dose measurements collected at screening and immediately pre-dose.	Week 24 and 48
Change From Baseline in CD8 Cell Count at Week 24 and 48	Change from baseline in CD8 cell count measured as cells/µL. Baseline value calculated as average of pre-dose measurements collected at screening and immediately pre-dose.	Week 24 and 48
Time to Virological Failure	Time to virologic failure based on observed HIV-1 RNA levels and failure events (death;permanent discontinuation of drug;lost to follow-up[LTFU];new anti-retroviral drug added [except background drug change to drug of same class];or on open label for early non-response or rebound). Failure:at Time 0 if level not <400 copies/mL (2 consecutive visits) before events or last available visit;at time of earliest event if level <400 copies/mL (2 consecutive visits);failure if level >=400 copies/mL (2 consecutive visits) or 1 visit >=400 copies/mL followed by permanent discontinuation of drug or LTFU.	Week 48
Number of Participants With Genotypic Susceptibility Score (GSS) and Phenotypic Susceptibility Score (PSS) at Screening	Number of participants with GSS and PSS were used as surrogates for genotype and phenotype. Genotypic and phenotypic resistance to protease inhibitors(PIs), nucleoside reverse transcriptase inhibitors(NRTIs) and non-nucleoside reverse transcriptase inhibitors(NNRTIs) were evaluated at screening (not at baseline), by Monogram Biosciences PhenoSense genotyping (GT) assay. Score was determined for each drug in OBT, giving 1:drug 'sensitive'/'susceptible' and 0:'resistant'. GSS and PSS score range:0 to >3. Genotypic enfuvirtide value was used for PSS, no phenotypic enfuvirtide was recorded.	Screening
Number of Participants With Change in GSS and PSS From Screening at the Time of Treatment Failure Through Week 24	Number of participants with GSS and PSS were used as surrogates for genotype and phenotype. Genotypic and phenotypic resistance to PIs, NRTIs, NNRTIs were evaluated at screening and time of treatment failure analyzed through Week 24 visit, by Monogram Biosciences PhenoSense GT assay. Score was determined for each drug in OBT, giving 1:drug 'sensitive'/'susceptible' and 0:'resistant'. GSS and PSS score range:0 to >3. Genotypic enfuvirtide value was used for PSS, no phenotypic enfuvirtide was recorded.	Screening and time of failure through Week 24
Number of Participants With Change in GSS and PSS From Screening at the Time of Treatment Failure Through Week 48	Number of participants with GSS and PSS were used as surrogates for genotype and phenotype. Genotypic and phenotypic resistance to PIs, NRTIs, NNRTIs were evaluated at screening and time of treatment failure analyzed through Week 48 visit, by Monogram Biosciences PhenoSense GT assay. Score was determined for each drug in OBT, giving 1:drug 'sensitive'/'susceptible' and 0:'resistant'. GSS and PSS score range:0 to >3. Genotypic enfuvirtide value was used for PSS, no phenotypic enfuvirtide was recorded.	Screening and time of failure through Week 48
Number of Participants Per Tropism Status at Baseline and at the Time of Treatment Failure Through Week 24	Number of participants per tropism status (C-X-C chemokine receptor 5 {CCR5} [R5], C-X-C chemokine receptor type 4 {CXCR4} [X4], Dual/Mixed [DM], or Non-reportable/Non-phenotypable [NR/NP]) at baseline and time of treatment failure analyzed through week 24 visit. Treatment failure defined as discontinuation due to insufficient clinical response. HIV-1 RNA viral load <500 copies/ml categorized as below lower limit of quantification (BLQ). The assessment for time of treatment failure was defined as the last on treatment assessment.	Baseline and time of failure through Week 24
Number of Participants Per Tropism Status at Baseline and at the Time of Treatment Failure Through Week 48	Number of participants per tropism status R5, X4, DM, or NR/NP at baseline and time of failure analyzed through week 48 visit. Treatment failure defined as discontinuation due to insufficient clinical response. HIV-1 RNA viral load <500 copies/ml categorized as BLQ. The assessment for time of treatment failure was defined as the last on treatment assessment.	Baseline and time of failure through Week 48
