E.3 | Principal inclusion criteria |
1. Subject has documented HIV-1 infection with a plasma HIV-1 RNA > 1,000 copies/mL at Screening. 2. Subject is ART-experienced (defined as on stable ART for at least the last 2 months) and is either currently experiencing virologic failure to RAL or experienced virologic failure to RAL >8 weeks prior to Screening (with documented genotypic and/or phenotypic RAL resistance at time of failure) and is currently experiencing treatment failure on a subsequent regimen 3. Subject has documented RAL genotypic resistance on Screening genotype 4. Subject has documented genotypic or phenotypic resistance to at least one drug from each of three or more of all approved classes of ART based on Screening genotype/phenotype and/or historical genotype/phenotype data. 5. Subject is >18 years of age. A female is eligible to enter and participate in the study if she falls into one of the following categories: a. Non-childbearing potential defined as pre-menopausal females with a documented tubal ligation, hysterectomy or bilateral oophorectomy; or postmenopausal defined as 24 months of spontaneous amenorrhea; or, b. Child-bearing potential, with a negative pregnancy test at screen and a negative pregnancy test at Day 1, who agrees to use one of the methods of contraception listed below. |

E.4 | Principal exclusion criteria |
1. Any pre-existing mental, physical, or substance abuse disorder which, in the opinion of the investigator, may interfere with the subject�s ability to comply with the dosing schedule and/or protocol evaluations (including alcohol or drug abuse) or which may compromise the safety of the subject. 2. Pregnant women and women who are breastfeeding. 3. Any evidence of an active Centres for Disease Control and Prevention Category C disease except cutaneous Kaposi�s sarcoma not requiring systemic therapy at the Screening visit. Subjects may be enrolled provided they are on a stable, anti-infective treatment or prophylaxis regimen and are clinically improving at the Baseline visit. 4. Current use and/or anticipated need for EFV, NVP, FPV/RTV or TPV/RTV during the Functional Monotherapy or Combination Phases of the study. 5. Subjects who require treatment with any of the following medications within 15 days of commencement of investigational product, or anticipated need during the study: Etravirine (unless co-administered with LPV/RTV or DRV/RTV), rifampin, rifabutin, phenytoin, pheonobarbital, barbiturates, glucocorticoids, modafinil, oxcarbazepine, pioglitazone, troglitazone, carbamazepine, St. Johns wort. 6. Previous participation in an experimental drug and/or vaccine trials (s) as defined in the protocol, prior to the first dose of study medication. 7. History of ongoing or clinically relevant pancreatitis or hepatitis within the previous 6 months. Asymptomatic individuals with chronic hepatitis B and hepatitis C virus (HBV, HCV) infection will not be excluded, but should be carefully assessed if therapy specific for HCV infection is required; subjects who are anticipated to require such therapy during the first 24 weeks of the study should be excluded. Any subjects with evidence of cirrhosis with or without hepatitis viral co-infection should be excluded. 8. History of upper gastrointestinal bleed (unless in the opinion of the Investigator and Sponsor the primary cause was reversible and has been adequately treated) and/or subjects with active peptic ulcer disease 9. Screening haemoglobin <10g/dL (100g/L). |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary efficacy endpoint for this study is the mean change from Baseline (Day 1) in plasma HIV-1 RNA at Day 11 (sample for evaluation of plasma HIV-1 RNA to be taken prior to Day 11 background treatment optimization). |
