There are 4 clinical trials
The purpose of this study is to look at the safety and efficacy of a combination of 3 new antiretroviral drugs: darunavir, etravirine and MK-0518 (raltegravir) in patients who have multi-resistant viruses and limited treatment options. An optimized background regimen that may include nucleoside reverse transcriptase inhibitors (NRTIs) and enfuvirtide can be added, if possible, to this combination. Patients will undergo treatment for 48 weeks and virological efficacy will be evaluated at week 24.

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

Description: Patients will undergo a neuropsychological test battery where multiple standardized test will be undertaken to assess 7 different domains; Verbal Fluency, Executive Functioning, Speed of Information Processing, Learning, Memory, Attention/Working Memory, Motor skills. Raw scores can be calculated per domain and as a composite score. Differences in mean changes in composite score between baseline and end of study will be assessed with a paired T-test. A p-value <0.05 will be considered statistically significant. Within-arm changes will be assessed using Wilcoxon signed rank tests, and between-group comparisons will be evaluated with Wilcoxon rank sum tests. Multivariate analyses will be performed to analyse differences in the primary endpoints between the study groups.
Measure: To evaluate the neurocognitive performance as measured by neuropsychological test composite score after 12 weeks in stable HIV-infected patients switched from Atripla to Eviplera compared to a control group of patients on Atripla. Time: 12 weeksDescription: The aim is to investigate if there is a correlation between improvement on neuropsychological test scores after 12 weeks of Eviplera therapy, and changes on fMRI after 12 weeks of Eviplera therapy. If there is a correlation, that means fMRI could be used to evaluate neurocognitive decline. Basically, we will asses if there is a correlation between ∆neuropsychological score and ∆fMRI-score. Because this is ordinal data, we will use a Spearman rank-order correlation to calculate a correlation-coefficient.
Measure: to assess the correlation between neurocognitive improvement (neuropsychological evaluation) and functional imaging (fMRI) after switching Atripla to Eviplera Time: 12 weeksDescription: The aim is if an improvement in neuropsychological test scores after 12 weeks of Eviplera therapy is correlated with an improvement of quality of life. Basically, we will assess if there is a correlation between ∆neuropsychological score and ∆SF-36 total score. Because this is ordinal data, we will use a Spearman rank-order correlation to calculate a correlation-coefficient.
Measure: to evaluate correlation between neurocognitive performance and health related quality of life measured by SF-36 total score after switching from Atripla to Eviplera. Time: 12 weeksDescription: With this study, we want to investigate the effect of switching Efavirenz (as a component of Atripla) to Rilpivirine (as a component of Eviplera) on neurocognition. Our hypothesis is that neurocognition (as measured by neuropsychological testing scores) will improve when switching from Efavirenz (as a component of Atripla). If that is the case, hypothetically a lower or higher drug level of Efavirenz (as a component of Atripla) could have an effect on neurocognition (as measured by neuropsychological test scores). We will assess the correlation between drug level of Efavirenz or Rilpivirine and changes in neurocognitive function as measured by neuropsychological testing, and fMRI changes by regression analyses using drug levels as an independent variable and neuropsychological test scores as a dependent variable.
Measure: to assess drug levels of Efavirenz (as a component of Atripla) and Rilpivirin (as a component of Eviplera) in relation to changes in neurocognitive performance and fMRI in both patient groups. Time: 12 weeksDescription: In our study, we will use the PROMIS instruments Anxiety, Depression, Sleep disturbance and Satisfaction with social roles and activities. These are all short forms containing 8 questions or statements. Patients are asked to rate the questions from 1-5 into which extent they believe them to be true; 1 being not at all and 5 being very much. For each short form, a score will be calculated by adding the values of the response to each question. PROMIS provides a score conversion table where the score can be translated into a T-score. This rescales the patient's score into a standardized score with a mean of 50 and a standard deviation of 10. In order to provide these results, PROMIS uses a calibration sample containing data from over 21000 respondents. Differences in mean changes between baseline and end of study, as well as between the two study groups will be calculated using a paired T-test.
Measure: to evaluate the usefulness of PROMIS instruments in HIV research Time: 12 weeksFor 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.
