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 1)
April 2, 2012 updated by: ViiV Healthcare
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 are infected with R5-tropic virus exclusively.
This study will involve more than 100 centers from the US and Canada 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.

Change From Baseline in Viral Load at Week 24 and Week 48 by Overall Susceptibility Score (OSS) at Screening
Time Frame: Baseline, Week 24 and Week 48
|
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.
