1 A Multicenter, Randomized, Double-Blind, Comparative Trial Of A Novel CCR5 Antagonist, UK-427,857, In Combination With Zidovudine/Lamivudine Versus Efavirenz In Combination With Zidovudine/Lamivudine For The Treatment Of Antiretroviral-Naive 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 goal of this study is to compare the safety and efficacy of maraviroc (UK-427,857) versus efavirenz, when each are combined with two other antiretroviral agents, in patients who are previously naive to antiretroviral therapy. This study will involve approximately 200 centers from around the world to achieve a total randomized subject population of 1071 subjects. Patients will be randomly assigned to one of three groups: maraviroc (UK-427,857) 300 mg once daily added to zidovudine/lamivudine (300 mg/150 mg twice daily), Maraviroc (UK-427,857) 300 mg twice daily added to zidovudine/lamivudine (300 mg/150 mg twice daily) or efavirenz (600 mg once daily) added to zidovudine/lamivudine (300 mg/150 mg twice daily). The study will enroll over approximately an 18 month period (5 months Phase 2b run-in, 13 months Phase 3) with 96 weeks of treatment. This may be extended for an additional 3 years depending on the results at 96 weeks. Physical examinations will be performed at study entry, weeks 4, 8, 12, 16, 20, 24, 32, 40, 48, 60, 72, 84 and 96. Blood samples will also be taken at study entry, weeks 2, 4, 8, 12, 16, 20, 24, 32, 40, 48, 60, 72, 84 and 96. Additionally, blood samples will be drawn twice, at least 30 minutes apart, at weeks 2 and 48 for maraviroc (UK-427,857) pharmacokinetic analysis. As part of this clinical study a blood sample will be taken for non-anonymized pharmacogenetic analysis. Patients will undergo a 12-lead electrocardiogram at study entry, weeks 24, 48 and 96. A computerized tomography (CT) scan will also be performed, at selected centers, at study entry and week 96. Patients will be asked to complete a symptom distress questionnaire at study entry, weeks 12, 24, 48 and 96.

3 A Phase IV, Open-label Single-arm Study Investigating the Pharmacokinetics and Pharmacodynamics of the Antiretroviral Combination of Rilpivirine and Ritonavirboosted Darunavir in Therapy-naive HIV-1 Infected Patients.

For patients who are starting to take antiretroviral medication (to treat HIV) for the first time, there are now a variety of different medicines which may be taken together as a combination in order to form an effective treatment which suppresses the virus for prolonged periods of time. Currently, national guidelines recommend the use of two different drugs of one type (the nucleoside/ nucleotide reverse transcriptase inhibitors, NRTI often known as "nukes") with a third drug from one of two other types (either a nonnucleoside reverse transcriptase inhibitor, known as an NNRTI or "nonnuke", or a protease inhibitor, known as a PI) to form a treatment regime of three active drugs. In the UK and Europe, all PIs are given in combination with a small dose of a second PI, ritonavir, which has the effect of boosting the levels of the active PI in the bloodstream. The investigators know from both research studies and patient experience in clinic that a combination of a ritonavirboosted PI with an NNRTI achieves similar results in suppressing the HIV virus, compared to the use of either a PI or NNRTI with 2 NRTI as described above. In this study, the investigators will observe the combination of two licensed antiretroviral medications, ritonavirboosted darunavir(DRV/r) and rilpivirine (RPV), in suppressing virus when given to patients who are commencing treatment for HIV infection for the first time. Both of these drugs are licensed for treatment of patients with HIV in the UK and Europe, and are currently in standard clinical use. The study will monitor this treatment over the first 48 weeks. The investigators will also examine the levels of both drugs in the bloodstream during the first 4 weeks of starting this regimen, to confirm that they remain at levels which the investigators know to be effective against the virus.

4 A Phase IV 48 Week, Open Label, Pilot Study of Darunavir Boosted by Cobicistat in Combination With Rilpivirine to Treat HIV+ Naïve Subjects (PREZENT)

Current HIV treatment guidelines recommend the use of triple-drug therapy (two nucleoside reverse transcriptase inhibitors and either a protease inhibitor, non-nucleoside reverse transcriptase inhibitor, or an integrase inhibitor) for the treatment of antiretroviral (ARV)-naïve patients. With the introduction of highly active antiretroviral therapy (HAART), patients with HIV are living much longer. With the increasing lifespan of persons with HIV, long-term complications from therapy as well as the occurrence of co-morbidities with aging have prompted HCPs to re-think the current treatment paradigm and consider novel combinations of ARVs. All of the currently approved HIV antiretrovirals have been implicated in causing long-term toxicities; however the greatest body of evidence for long-term metabolic effects has implicated the nucleoside reverse transcriptase (NRTI) class. By utilizing a non-NRTI treatment regimen, it is hypothesized that many of these long-term metabolic effects (renal toxicity, bone loss, body fat changes) can be delayed or avoided altogether. The clinical data on novel combinations is currently limited but rapidly growing and has included several combinations that have utilized darunavir. This study will be the first of its kind using the unique combination of darunavir/cobicistat and rilpivirine. Currently, this drug combination is not a recommended option for first time treatment of HIV
