Clinical Trials

1 Antiretroviral Activity and Tolerability of Once Daily Etravirine in Treatment-Naïve Adults With HIV-1 Infection

The main study is a single arm, open-label, prospective study to assess antiretroviral activity and tolerability of etravirine (TMC-125) 400 mg once daily, given with fixed-dose tenofovir/emtricitabine, in treatment-naïve HIV-1-infected men and women. There are also a genital secretions pharmacokinetic (PK) sub-study and a metabolic sub-study. The purpose of the genital secretions PK sub-study is to gain information about drug levels and HIV-1 RNA in genital secretions when subjects are taking etravirine. The purpose of the metabolic sub-study is to learn about the effects of etravirine on body composition, as well as lipid and glucose levels.

4 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.

5 Strategic Study of Dual-therapy With Darunavir/Ritonavir and Rilpivirine QD Versus Triple-therapy in Patients With Suppressed Viral Load: Virological Efficacy and Evaluation of Non-HIV Related Morbidity.

Clinical approach to HIV infection treatment is based on the use of highly active antiretroviral therapies (HAART) and recent national and international guidelines for guiding HIV therapy recommend the use of triple-combination therapy using antiretrovirals with 2 nucleos(t)ide inhibitors [N(n)RTI] as backbone plus a third drug to be chosen among a boosted protease inhibitor (PI/r), a nonnucleoside inhibitor (NNRTI) or an integrase inhibitor (II). In spite of evident efficacy of HAART, as demonstrated by survival increasing, long term side effects, as for example the impact on renal function, remain principal problem. In patient with risk factor for renal disease, a reduction of eGRF (estimated Glomerular Filtration Rate) between 90 and 60 mL/min/1,73 m2 could be already considered as a risk condition [1,2]. Efficacy of HAART, with increase of media survival and the parallel decrease of mortality, has underlined the necessity to reflect on long term HAART effects [3]. There are many evidences of HAART-related toxicity that, in spite of the necessity of a life-saving therapy, focus on the additional costs of this situation, in terms of health as well as in terms of economic costs. Particular attention has been focused on the impact of some drugs on renal function, as tenofovir, especially on tubule, without forgetting the modification of lipid and bone metabolisms. According to further studies which have evidenced the potential of some recently introduced molecules [4,5], the investigators had the need to realize a study to deepen the feasibility of a dual-therapy that permit to exclude NRTIs from the backbone, with the aim to prevent NRTIs-related long-term toxicity. The investigators have designed a prospective randomized controlled trial, open-label, with a duration of 96 weeks, to compare the efficacy of a dual-therapy based on rilpivirine 25mg plus darunavir 800mg/ritonavir 100mg QD, in HIV-positive subjects with suppressed viremia from at least 3 months. In fact, there are a few data about association of these drugs, which it has been shown to be safe, well tolerated, and with a strong pharmacological synergy, without nucleos(t)idic backbone, while the necessity to minimize the costs toxicity-related is becoming increasingly compelling. According to clinical experience and literature data, the investigators hope this study shows positive results in term of immune-virological efficacy, as well as in term of decrease of VACS index - a complex parameter which has the purpose to quantify general organic decay - and markers of lipid and bone metabolism, in group which receives dual-therapy versus the group with standard therapy.

6 Dolutegravir + Rilpivirine Switch Study (DORISS): Pilot and Noninferiority Trial Comparing Dolutegravir + Rilpivirine vs. Continued HAART (Highly Active Antiretroviral Therapy) in Patients With Plasma HIV RNA ≤ 50 Copies/mL for at Least 2 Years

The primary objective of the study is to evaluate the capacity of Dolutegravir + Rilpivirine vs. continued triple combination HAART to maintain plasma HIV RNA ≤ 50 copies/ml throughout 24 weeks in patients with plasma HIV RNA ≤ 50 copies/mL for at least 2 years under conventional HAART (2 NNRTI + 3rd agent). The main secondary objectives are the following: - % of virologic success (plasma viral load ≤ 50 copies/mL) at W24 and W48 - % of patients who maintain a plasma viral load ≤ 50 copies / ml from D0 to W48 - % of virological failure defined by two consecutive plasma viral load > 50 copies/mL - Profile of genotypic resistance in case of virological failure. The trial will be conducted according to the design below, in 3 steps: - Step 1: enrollment of 80 patients (40 in each arm) - Step 2: enrollment on hold until W16 data from the 40 patients enrolled in the intervention arm have been analyzed. - Step 3: resumption and completion of enrollment if conditions for resuming enrollment at the end of step 2 are fulfilled, i.e. if the percentage of patients randomized to the intervention arm who have a plasma viral load ≤ 50 copies/mL from D0 to W16 is significantly > 70%, which translates in a maximum of 6 virologic failures.

7 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

10 QD Isentress as Switch Strategy in Virologically Suppressed HIV-1 Infected-Patient

Raltegravir (RAL) is a very effective antiretroviral drug with a favorable long term tolerability. RAL offers many advantages such as lack of drug-drug interactions, a good safety profile particularly on lipids, inflammation and bone parameters. Ral can be an very interesting for patient with comorbidities and comedications, intolerance or toxicities with their current ARV treatment. However its current formulation of one tablet of 400mg twice a day coul not suit many patients. A new once-a-day formulation of RAL has been developed, with two tablets of 600 mg QD. Pharmacokinetic study in healthy volunteers has shown that this dosing provides increased RAL exposure compared to the standard formulation of 400 mg given twice a day. The objective of this study is to evaluate the maintain of virologic suppression with raltegravir 600mg 2 tablets qd as part of a triple antiretroviral regimen in virologically controlled patients.

11 Efficacy and Safety of a Simplification Strategy Based on Dolutegravir and Darunavir / Cobicistat vs Optimized Treatment in Suppressed HIV-1-infected Patients Carrying Archived Multidrug Resistance Mutations.

The availability of antiretroviral therapy has led to a reduction in morbidity and mortality in patients with chronic HIV infection. The treatment, however, is not free of side effects, has potential interactions with other medications, is expensive and can be complex, especially in those patients who are very experienced and with mutations that give them resistance to multiple drugs. For this reason, the development of simplification strategies that avoid unnecessary exposure to antiretroviral agents remains of great interest. This is a simplification study, in which the investigators try to evaluate that with less medication the investigator can maintain the same virological control of the disease. This would mean a lower burden of medication for patients, facilitating its administration and reducing the number of unwanted side effects. Specifically, the investigators intend to evaluate the treatment with Darunavir / cobicistat plus Dolutegravir as a simplification strategy, since both drugs are taken once a day, have a powerful antiviral activity, even against antiretroviral resistant viruses, and are among the best tolerated (with fewer side effects). The results reported in some observational studies suggest that two-drug therapy (bitherapy) as a simplification strategy could also be safe and effective, however, as far as the investigators know, there are no data and clinical trials that specifically evaluate darunavir / cobicistat plus dolutegravir as a strategy of simplification.

13 HIV Drug Resistance Profiles Among Individuals Failing Tenofovir/Lamivudine and Dolutegravir First Line Regimen in Brazil

Brazil was the first middle-income country to provide free and universal access to antiretroviral drugs to HIV infected individuals. Since 2014 local guidelines recommend that all HIV infected individuals be started on therapy regardless of CD4 count. Since January 2017, all patients are started on a DTG containing triple regimen. As of November 2018, 170,000 individuals were receiving DTG through the public health system. It is a public health priority to evaluate the risk of virologic failure and the subsequent development of INSTI resistance in these real-life settings. Our preliminary data from Brazil indicated a high virologic failure rate of 8% after 18 months of treatment TL+D. Our central hypothesis is that TDR may be associated and contribute to virologic failure with DTG in clinical practice. To test this central hypothesis, we will identify PLWH failing DTG containing regimens in Brazil. The insights generated with these studies will contribute to a more effective use of second generation INSTI in the future.

NCT04453436 HIV Drug Resistance Drug: Tenofovir Disoproxil

Among 84 individuals who experienced virologic failure during first-line treatment with TL+D, 11 presented low level viremia (50-500 c/mL), In five patients (5.9%) major resistance associated mutations were detected at IN: 2 patients with R263Q, one with G118R, one with E138A, and one with R263R/K in IN plus K70E+M184V in RT. --- R263Q --- --- G118R --- --- E138A ---
