To assess efficacy as measured by percentage of subjects with HIV-1 RNA <48 copies/mL and <400 copies/mL. Change from baseline in log10 transformed HIV-1 RNA levels. To assess the pharmacokinetics (PK) and pharmacokinetic/pharmacodynamic (PK/PD) relationship of UK-453,061. To assess pharmacokinetic parameters of UK-453,061 AUC24, Cmax and C24h (PK sub-study). |

E.3 | Principal inclusion criteria |
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 &#8805;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. |

Subjects on a stable (>30 days) secondary OI prophylaxis regimen or chronic treatment are eligible for the study, as are subjects on a primary OI prophylaxis regimen of any duration, except Trimethoprim-sulfamethoxazole. Subjects on primary, secondary prophylaxis and therapy with Trimethoprim-sulfamethoxazole must be in therapy >60 days. 2. Subjects on therapy for Hepatitis B. 3. Subjects with acute Hepatitis B and/or C within 30 days of randomization. 4. Subjects with Hepatitis C on therapy with interferon and/or ribavirin for <60 days. 5. Absolute CD4+ cell count <200 cells/mm3. 6. Treatment for an active OI, or unexplained temperature >38.5 C, for 7 consecutive days within 30 days prior to randomization. 7. Prior treatment with efavirenz, emtricitabine, or tenofovir DF, or with any other antiretroviral therapy for more than 14 cumulative days at any time. 8. Active alcohol or substance abuse sufficient, in the investigators judgment, to prevent adherence to study medication and/or follow-up. 9. Lactating women, or planned pregnancy during the trial period. 10. Suspected acute HIV-1 infection. 11. Initiation of therapy with a potentially myelosuppressive, neurotoxic, hepatotoxic and/or cytotoxic agent within 60 days prior to randomization or the expected need for such therapy during the study period. 12. Malignancy requiring parenteral therapy that must be continued during the trial. 13. Documented or suspected pancreatitis within 30 days prior to randomization. 14. Renal insufficiency defined as a serum creatinine greater than 3 times the upper limit of normal or a creatinine clearance of less than 50 mL/min. 15. Total bilirubin greater than &#8805;1.5 times the upper limit of normal. 16. AST and/or ALT greater than 3 times the upper limit of normal. 17. Male subjects with a baseline QT of >450 msec and female subjects with a baseline QT of >470 msec. 18. Subjects with cardiac events (MI, bypass surgery, angioplasty) within 6 months of randomization. 19. Cirrhosis of the liver. 20. Absolute neutrophil count &#8804;750 cells/mm3. 21.
