In HIV-1 infected patients in the United States, maraviroc (UK-427,857) is approved for use as part of combination antiretroviral treatment in treatment-experienced and treatment-naive adult subjects. At least 50% of treatment-experienced patients are infected with R5-tropic HIV-1 exclusively. However, even in patients infected with a dual tropic (R5 + X4) phenotype, a large proportion of the virus population still uses CCR5 exclusively. Thus, the purpose of this study is to evaluate the antiretroviral activity, and safety, of maraviroc (UK-427,857) (in combination with other agents) in HIV infected, treatment experienced patients who are failing their current antiretroviral regimen and not infected with R5-tropic virus exclusively. This study will involve more than 200 centers globally to achieve a total randomized subject population of 192 subjects. Patients will be randomly (1:1:1) 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. Randomization was stratified by Enfuvirtide use in OBT (yes/no) and Screening HIV-1 RNA level (viral load) (<100,000/≥ 100, 000 copies per milliliter [copies per mL]). The study will enroll over approximately a 9 month period with 48 weeks of treatment. 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.","brief_summary_OneLinkTx":"","brief_title_OneLinkTx":"","brief_title":"Trial of Maraviroc (UK-427,857) in Combination with Optimized Background Therapy Versus Optimized Background Therapy Alone for the Treatment of Antiretroviral-Experienced NonCCR5-Tropic HIV-1 Infected Subjects","conditions":[{"DisplayValue":"Human Immunodeficiency Virus (HIV)","DisplayValue_OneLinkTx":"","InternalValue":"CON_HIV","LookupValue":"HIV infections","LookupValue_OneLinkTx":""}],"created_date":"09/15/2018 18:05:51","criteria":"Inclusion Criteria: - Men or women at least 16 years of age (or minimum age as determined by local regulatory authorities) - HIV-1 RNA viral load of greater than or equal to 5,000 copies/mL - Stable pre-study antiretroviral regimen, or on no antiretroviral agents, for at least 4 weeks - Documented genotypic or phenotypic resistance to two of the four antiretroviral drug classes, OR, Antiretroviral-class experience greater than or equal to 3 months (sequential or cumulative) with at least three of the following: One nucleoside or nucleotide reverse transcriptase inhibitor (excluding low-dose ritonavir) and/or enfuvirtide - Be willing to remain on randomized treatment without any changes or additions to the OBT regimen, except for toxicity management or upon meeting criteria for treatment failure - A negative urine pregnancy test at the baseline visit for Women of Child Bearing Potential (WOCBP) - Effective barrier contraception for WOCBP and males Exclusion Criteria: - Patients requiring treatment with more than 6 antiretroviral agents (excluding low-dose ritonavir) - Prior treatment with maraviroc (UK-427,857) or another experimental HIV entry inhibitor for more than 14 days - Suspected or documented active, untreated HIV-1 related opportunistic infection (OI) or other condition requiring acute therapy - Treatment for an active opportunistic infection, or unexplained temperature >38.5 degrees Celsius for 7 consecutive days - Active alcohol or substance abuse sufficient, in the Investigator's judgment, to prevent adherence to study medication and/or follow up - Lactating women, or planned pregnancy during the trial period - Significant renal insufficiency - Previous therapy with a potentially myelosuppressive, neurotoxic, hepatotoxic and/or cytotoxic agent within 30 days prior to randomization or the expected need for such therapy during the study period - Documented or suspected acute hepatitis or pancreatitis within 30 days prior to randomization - Significantly elevated liver enzymes or cirrhosis - Significant neutropenia, anemia or thrombocytopenia - Malabsorption or an inability to tolerate oral medications - Symptomatic postural hypotension or severe cardiovascular or cerebrovascular disease - Certain medications - Malignancy requiring parenteral chemotherapy that must be continued for the duration of the trial - R5 virus phenotype only - No option to use at least one non-nucleoside reverse transcriptase inhibitor or protease inhibitor, or enfuvirtide, based on resistance testing - Any other clinical condition that, in the Investigator's judgment, would potentially compromise study compliance or the ability to evaluate safety/efficacy","detailed_description":"(i) Subjects remained on their assigned therapy for 48 weeks, unless the subject was discontinued early for protocol-defined treatment failure or other reasons such as adverse event, loss to follow-up, withdrawal of consent, or death.
