E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective is to assess efficacy of UK-453,061 when used in combination with tenofovir DF/emtricitabine, as measured by percentage of subjects with HIV-1 RNA <48 copies/mL at 48 weeks. |
|
E.2.2 | Secondary objectives of the trial |
• To assess efficacy as measured by percentage of subjects with HIV-1 RNA <48 and <400 copies/mL. • Change from baseline in log10 transformed HIV-1 RNA levels. • To assess the pharmacokinetic (PK) and pharmacokinetic/pharmacodynamic (PK/PD) relationship of UK-453,061. • To assess pharmacokinetic parameters of UK-453,061 AUC24, Cmax and C24h (PK substudy). |

E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
1. Molecular Profiling Supplement, Version and Date: Final 28 July 2008
The primary objective of this additional research component is to collect, store, and use samples to investigate possible associations between genomic and metabonomic variation: • in relation to response to the study drugs, and • in relation to characteristics of the disease/condition under study in the associated clinical trial, and related conditions.
In addition, samples may be used as controls in genomic and metabonomic investigations of the causes, natural history, and other aspects of important diseases and conditions for which Pfizer is researching new or improved drug therapies.
Scientific information about these differences among groups of subjects can help researchers to better understand the response of subjects to investigational drugs and to learn more about diseases/conditions for which we are developing treatments.
Samples collected will be stored in Pfizer’s Exploratory Research Biobank in the USA.
2. There is a PK sub-study written within the same protocol (A5271015). |

E.3 | Principal inclusion criteria |
Subjects must meet all of the following inclusion criteria to be eligible for enrollment into the trial: 1. Evidence of a personally signed and dated informed consent document indicating that the subject (or a legally acceptable representative) has been informed of all pertinent aspects of the study. 2. Male or female at least 18 years of age available for a follow-up period of at least 96 weeks. 3. HIV-1 RNA viral load of ≥1,000 copies/mL measured by the Roche COBAS® AmpliPrep/COBAS® TaqMan® HIV-1 test at the screening visit. 4. Negative urine pregnancy test at the Day 1 visit, prior to receiving the first dose of study medication, for Women of Child Bearing Potential (WOCBP). • NOTE: WOCBP includes any female who has experienced menarche and who has not undergone successful surgical sterilization or is not post-menopausal (ie, no menstrual periods for at least 2 years). Even women who are using oral, implanted or injectable contraceptive hormones or mechanical products (intrauterine devices; barrier methods: eg,condom or diaphragm with spermicide) to prevent pregnancy, who are practicing abstinence, or who have a partner that is sterile (eg, vasectomy), should be considered to be of child bearing potential. 5. Effective barrier contraception for WOCBP and males. In addition, WOCBP must use another acceptable method of contraception for the duration of the study and for 28 days after leaving the study. Acceptable contraception includes, but is not limited to, oral, implanted or injectable hormone therapy and intrauterine devices. 6. Subjects who are willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures. |

E.4 | Principal exclusion criteria |
Key Exclusion Criteria have been selected due to limitations on space in the Annex 1 (please refer to Protocol for the completed list):
