To evaluate the efficacy, safety, and pharmacokinetics of lamivudine (3TC) combined with zidovudine (AZT), stavudine (d4T), or didanosine (ddI) in comparison with d4T or ddI monotherapy in HIV-infected patients with no prior nucleoside therapy. 3TC may be uniquely effective in combination with AZT due to the interaction of AZT and 3TC resistance mutations. One explanation is that the M184V mutation, which confers resistance to 3TC, suppresses AZT resistance. This benefit of 3TC may not extend to combination therapy with other nucleoside analogs.

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.

Racivir ® (RCV) is an experimental drug which means it is not approved for use by the United States Food and Drug Administration (FDA), but it can be used in research studies like this one. RCV (Racivir®) is part of a class of drugs known as "Nucleoside Reverse Transcriptase Inhibitors" (NRTIs), which are intended to block a further increase in the amount of HIV virus in the body. Laboratory research suggests that RCV (Racivir®) may be effective in patients who have developed resistance to other NRTIs, particularly 3TC (lamivudine, Epivir®). However, a study of RCV (Racivir®) has not been done with patients who have previously been treated with other HAART (Highly Active Antiretroviral Therapy -- taking multiple HIV drugs at once) medications including 3TC (lamivudine, Epivir®). The purpose of this study is to evaluate the safety and effectiveness of RCV (Racivir®) when used together with other HIV drugs in people who have previously been treated with 3TC (lamivudine, Epivir®) and are failing with their current HAART treatments. This study will include a total of 60 HIV infected, HAART-experienced subjects currently receiving 3TC (lamivudine, Epivir®) as part of their HAART therapy. The study will take place at approximately 11 study sites in the US and Latin America.

In this study the researchers will be enrolling patients who are failing their current antiretroviral regimen who also have resistance to 3TC or FTC. Patients will have their current antiretroviral regimen changed based on resistance testing and also be randomly assigned to either include, or not include 3TC/FTC in this new regimen. The purpose of the research is to investigate whether the change in therapy results in a decrease in the amount of virus particles and an increase in the CD4 cell count. In addition the researchers are investigating the relationship between the existence of resistance and the rate of decrease in viral load, and also to determine if continuing 3TC/FTC (despite being resistant to the medications) has any effect on the rate of decrease of viral load, or effect on CD4 counts.

HIV-1 infected patients receiving long-term therapy with lamivudine or emtricitabine (nucleoside reverse transcriptase inhibitors [NRTIs]) are at risk for the development of a mutation at position M184 on the HIV reverse transcriptase gene. This mutation confers resistance to both drugs (> 100 fold increase in IC50). In-vitro studies with elvucitabine have shown that HIV-1 isolates with the M184V mutation show only a 10-fold increase in IC50 as compared to wild type HIV-1. Achillion Pharmaceutical's intention is to demonstrate that 10 mg of elvucitabine, administered once per day for 14 days with continued background anti-HIV-1 medications, will demonstrate a fall in HIV-1 RNA plasma levels, as compared to baseline. The data from this study will guide dosing in future long-term studies in HIV-1 infected patients with the M184V mutation.

This is a multicenter, open-label, non-randomized, dual-arm pilot study to investigate the prevalence of the reverse transcriptase (RT) resistance mutations, K65R/x or L74V/x, in HIV-1 plasma from subjects experiencing confirmed first-time incomplete virologic suppression during treatment with an initial antiretroviral (ARV) regimen consisting of at least 12 weeks of TDF or ABC + emtricitabine (FTC) or lamivudine (3TC) + non-nucleoside reverse transcriptase inhibitor (NNRTI) or protease inhibitor (PI). Subjects will be followed until a substantial loss of virologic or immunologic control requires a treatment switch. Confirmed first-time incomplete virologic suppression is defined as an initial plasma HIV-1 RNA response < 400 copies/mL, and subsequent virologic rebound > 400 copies/mL measured at two consecutive times. Subjects will have a screening genotype to establish adherence to their non-suppressive TDF- or ABC-containing regimen by the presence of M184V (or other treatment-related primary) mutation and to demonstrate that the evolution of treatment-emergent RT mutations can be characterized. Twenty subjects (a maximum of 10 per arm) will be enrolled at 10-20 United States (U.S.) sites. If fewer than 20 subjects can be enrolled, the study may be discontinued early by the sponsor. Equal numbers of subjects on Arm A versus Arm B will be a goal.

Many patients who already harbor drug-resistant HIV require interruption of HAART due to poor compliance, poor quality of life, toxicity or development of resistance. In these patients interruption of HAART has a negative impact on patient immune status due to the reemergence of wild-type virus which is in general more pathogenic than HIV isolates containing resistance mutations. There is a need for "bridging" antiretroviral regimens that might prolong time off conventional HAART whilst waiting for a new regimen that is either fully suppressive or less toxic or less demanding for the patient.
GMB: Phase IV, Multicenter, Randomized, Open-Label Pilot Study of Truvada (TDF+FTC) or Emtricitabine (FTC) Alone Versus HAART Interruption in HIV-Infected Patients Who Need to Interrupt HAART and Who Are Infected With HIV Isolates Containing at Least 2 TAMs (or K65R) and M184V. --- K65R --- --- M184V ---

The purpose of this study is to determine the short term safety, tolerance, and antiviral effect of zidovudine (AZT) and amdoxovir (AMDX, DAPD) in combination, and whether the dosage for AZT can be reduced, potentially decreasing side effects, while maintaining antiviral effects. Study hypothesis: DADP in combination with AZT is safe and effective, and AZT dosing may be reduced, resulting in lower levels of AZT-monophosphate associated with toxicity and maintaining levels of AZT-triphosphate associated with efficacy.
Therefore, second line treatments that are currently in development should provide activity against resultant mutations, primarily M184V/I (17%) and much less commonly K65R (0 to 5%), and ideally prevent or be effective against mutations that may occur during second line therapy. --- M184V ---

The researchers are involved in a phase II, randomized, two-arm study, comparing the efficacy, safety, and tolerability of open-label ritonavir (RTV)-enhanced darunavir with Truvada to a 5-drug multi-class regimen including truvada, darunavir/ritonavir/maraviroc/and raltegravir on acutely HIV-1-infected, antiretroviral (ARV) drug-naïve men and women. Subjects will participate for at least 60 weeks and up to 96 weeks if in the opinion of the investigator and patient that continued therapy is in the patient's best interest. Hypotheses: - Multi-class antiretroviral therapy (ART) is superior to RTV-enhanced ATV in combination with Emtricitabine/Tenofovir DF (FTC/TDF) with respect to suppression of viral replication. - Multi-class ART is superior to RTV-enhanced ATV in combination with FTC/TDF with respect to immune reconstitution in peripheral blood and in the gastrointestinal mucosa. - Multi-class ART is equivalent to RTV-enhanced ATV in combination with FTC/TDF with respect to tolerability.

This may in part be due to the pharmacokinetics of Raltegravir in blood and gut tissue. Efavirenz will be the comparator antiretroviral drug in this study, with both drugs being used as part of a three-drug regimen with tenofovir and emtricitabine. The primary objectives are to determine differences in the effects of 2 anti-retroviral regimens, Raltegravir + Truvada versus Atripla, with respect to: 1. Viral load in plasma, genital tract (vaginal secretions), and gut (by in situ hybridization). 2. Latent viral reservoir (pro-viral DNA) in the peripheral blood and genital tract. 3. Immune effects (CD4/CD8 immunophenotypes) in gut and PBMCs and plasma cytokine profiles. The secondary objective is to determine the pharmacokinetics of Raltegravir in blood and gut tissue; relative tissue/compartment penetration compared to Efavirenz.

Description: Small artery elasticity is a measure of vascular function, estimated through analysis of the blood pressure waveform. A sensor is placed on wrist over the radial pulse. The blood pressure waveform of the pulse is recorded and analyzed the elasticity, or compliance, of the small (and large) vasculature. Impaired artery elasticity, or increased stiffness, is an early sign of vascular disease that predicts risk for future cardiovascular events.
Measure: Change in Small Artery Elasticity (mL/mmHg x100) From Baseline to Week 24 Time: Change from baseline to 24 weeksDescription: Large artery elasticity is a measure of vascular function, estimated through analysis of the blood pressure waveform. A sensor is placed on wrist over the radial pulse. The blood pressure waveform of the pulse is recorded and analyzed the elasticity, or compliance, of the large (and small) vasculature. Impaired artery elasticity, or increased stiffness, is an early sign of vascular disease.
Measure: Outcome Was Change in Large Artery Elasticity (mL/mmHg x100) From Baseline to Week 24 Time: Change from baseline to 24 weeksTo assess 48-week treatment responses, tolerability, and steady-state minimum plasma concentrations of ritonavir-boosted lopinavir monotherapy for salvage therapy in HIV-1 infected patients who failed antiretroviral regimens containing NRTI and NNRTI.

Frequency of opportunistic infections (OI) and disease progression.
Measure: • Proportion of patients with HIV-1 RNA levels of less than 400 copies/mL at week 24 and at week 48 Time: 48 weeksThe purpose of this study was to compare the use of lamivudine (3TC) or emtricitabine (FTC) alone vs. continuing a failing highly active antiretroviral therapy (HAART) regimen in HIV infected children, adolescents and young adults. The study was to see if there were changes in the HIV virus and if there were differences in immune function, viral load and medication side effects between the two groups over 28 weeks. Participants were assigned to either take 3TC or FTC alone or continue on his/her current failing HAART regimen. During the first 28 weeks of this study, if the participant was randomized to the continue HAART arm, he/she was not switched to a different or new, potentially suppressive HAART regimen, but continued on the current failing HAART regimen. However, if continuing HAART, the participant might be switched to a new regimen if their provider felt that it was clinically needed or the participant met certain study endpoints (e.g., drop in CD4, increase in viral load). At the end of 28 weeks, the participant had the choice of remaining on the assigned study group medication(s) or starting a new HAART regimen prescribed by his/her doctor. Then, they would be followed for another 24 weeks to compare the difference in immune function, viral load and medication side effects between the different groups.

Measure: Number of Participants Non-adherent as Measured by 3-day Recall Time: 28 WeeksThe study was conducted on people who were taking their first anti-HIV drug regimen (including an Non-Nucleoside Reverse Transcriptase Inhibitor (NNRTI), a type of anti-HIV drug) but the drugs in this regimen were not doing a good job of fighting their HIV infection. The main purpose of this study was to compare two other anti-HIV drug regimens to see how well they fight HIV. The study also looked at how well participants tolerate the drug regimens and how safe they are. The study was designed to determine whether taking the combination of lopinavir/ritonavir (LPV/r) plus raltegravir (RAL) works as well as what is usually used for second-line therapy: LPV/r plus the best-available nucleoside (nucleotide) reverse transcriptase inhibitor (NRTI) combination. Testing a regimen that does not include any NRTIs was important because NRTIs may no longer work for patients who received them as part of their first treatment regimen.
The most significant of these mutations include M184V, thymidine analogue mutations (TAMs), Q151M complex, and K65R. --- M184V ---
Recent data suggest that patients with isolated M184V-related NRTI resistance who subsequently switch to a boosted PI plus lamivudine (3TC)- or emtricitabine (FTC)-based regimen may achieve HIV-1 RNA suppression without the need to switch to more complex regimens [1]. --- M184V ---

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 weeksThe investigators aim to assess type and frequency of HIV drug resistance in adults presenting to the Infectious Diseases Institute (IDI) in Kampala, Uganda, and compare this data to patients from the Swiss HIV Cohort Study (SHCS). This study is a single-site, cross-sectional study. The Investigators' goal is to perform viral load measurements in 2750 HIV-infected patients who have been on ART for 6 months or more. Presuming a detectable viral load in 10%, resistance testing would then be performed in 250 patients on ART. All adult patients attending will be screened for enrollment. Furthermore, the investigators' goal is to perform resistance testing in 250 ART naive patients in order to detect transmitted resistance mutations. Investigators will therefore consecutively screen and enroll 250 ART naive patients who attend the clinic during the study period. For each participant, a case report form (CRF) form will be completed which includes social, as well as medical information. Investigators will ask each participant for permission to store plasma in case resistance testing must be repeated, and serum, in case of future research questions.
These analyses will be performed for all drug-resistance mutations pooled together (outcome-variable= patient has any drug resistance mutation), for drug resistance mutations against individual drug classes (outcome = patient has any drug resistance mutation to a particular drug class), and for the two resistance mutations (M184V and K103N) that have been most prevalent in previous studies in resource-limited settings. --- M184V ---

Measure: Viroligical failure Time: up to 12hrsDescription: •Assessment of local risk factors for treatment failure
Measure: Viroligical failure Time: up to 12hrsBackground: HIV attacks the immune system. Antiretroviral therapy (ART) is a combination of drugs used for treating HIV infection. For some people, ART drugs stop working against their HIV. Researchers want to see if a different form of the drug tenofovir (an ART drug currently approved by the FDA), combined with another drug, may help people whose HIV is resistant to ART. This combination pill is called F/TAF Objective: To study the safety and efficacy of the drug F/TAF, when used with other ART, for people whose HIV infection has been hard to control with available medicines. Eligibility: People age 14 years and older who have HIV infection and are enrolled in the DOTCOM (14-I-0009) protocol. Design: Participants will be screened with physical exam, medical history, and blood and urine tests. Participants will stay in the hospital for at least 10 days. For the first 9 days, they will take F/TAF by mouth along with their usual ART drugs. In the hospital, they will repeat the screening tests. Participants will have a DEXA scan, an x-ray that measures calcium and other minerals in the bones. Participants will lie on a soft table while the scanner passes over the lower spine and hips. Participants will get a supply of F/TAF and some new ART drugs to take at home. Participants will have follow-up visits in 1, 2, 4, 8, and 12 weeks. After the 12-week visit, they will come back about every 3 months for about 1 year. At these visits, participants will repeat the screening tests. They will discuss any problems taking their ART drugs. They may have another DEXA scan.

The fixed-dose combination of tenofovir-lamivudine-dolutegravir offers significant advantage as a potential second-line regimen compared to the World Health Organization standard of care second-line regimen of zidovudine-lamivudine-dolutegravir, in terms of cost, tolerability and monitoring requirements. The ARTIST study is a phase 2, randomised, double-blind, placebo-controlled trial aiming to determine the proportion of patients achieving virological suppression when recycling the tenofovir-emtricitabine/lamivudine backbone with dolutegravir (tenofovir-lamivudine-dolutegravir fixed-dose combination) as a second-line with and without a lead-in supplementary dose of dolutegravir, in patients failing a tenofovir-emtricitabine/lamivudine-efavirenz first-line regimen. There is evidence to suggest that even in the presence of resistance mutations to tenofovir and lamivudine (K65R or M184V/I), using this backbone with dolutegravir will provide an effective second-line regimen in patients who have failed a first-line regimen of tenofovir-emtricitabine/lamivudine-efavirenz. The strategy of giving a lead-in supplementary dose of dolutegravir is in view of the inducing effect of efavirenz on dolutegravir metabolism and transport that persists for 2 weeks after efavirenz is stopped; the inducing effect decreases with time after efavirenz is stopped. Given that these patients will have elevated viral loads, a high baseline risk of nucleoside reverse transcriptase inhibitor (NRTI) resistance and efavirenz resistance, and the inducing effect of efavirenz on dolutegravir metabolism and transport that persists for 2 weeks, this study will comprise two stages. The first stage will evaluate virological suppression in 62 participants initiated on the fixed-dose combination of tenofovir-lamivudine-dolutegravir with a lead-in supplementary dose of dolutegravir for the first 14 days. The study will progress to the second stage if this strategy proves effective, and 130 participants will then be randomised to receive the fixed-dose combination of tenofovir-lamivudine-dolutegravir with and without this lead-in dose. The primary endpoint is virological suppression (viral load <50 copies/mL) at 24 weeks. A pharmacokinetic sub-study will be conducted on 12 participants in stage 1 and 24 participants in stage 2, to assess the trough concentrations of dolutegravir and off-treatment concentrations of efavirenz at day 3, 7, 14, and 28. This is to evaluate the need for the lead-in supplementary dose of dolutegravir.

Measure: All-cause mortality Time: 48 weeksPatients infected and living with HIV are getting older and have more and more non-HIV co-morbidities. These expose them to polypharmacy that increases the risk of pharmacological interaction. Bictegravir, co-formulated with emtricitabine (FTC) and tenofovir alafenamide (TAF) (BIKTARVY) a new generation integrase inhibitor with a high genetic barrier and had no drug interaction may be a treatment of choice for participant over 65 years old who are HIV infected . BIKTARVY improve adherence and quality of life; and on the other hand it would limit the risks of pharmacological interaction. In addition, the use of TAF reducing the risk of long-term renal toxicity and adverse effects on bone would be of interest in this aging population and more at risk of osteoporosis.

While most patients achieve virological success, their treatments often need to be optimized in order to limit adverse events, drugs interactions and to improve adherence. The switch to dual regimen strategies represent one of the approaches for treatment optimization. Circulating HIV-1 resistant variants can be archived in viral reservoirs, where they can persist for an unknown duration and reemerge in case of therapeutic selective pressure. There is a need to assess the dynamic of archived Drug resistance associated mutations (DRAMs) clearance in cell-associated HIV DNA after a long period of virological control, in the perspective of ARVs recycling. The investigators postulate that it could be interesting in the future to recycle ARV drugs (that where classified as "resistant" in the past) in subsequent regimen. The question is particularly important for 3TC/FTC for subsequent new regimen and for the use of dual regimen (disappearance of M184V). Thus, the investigators propose a retrospective, longitudinal analysis on blood-cell-associated HIV-1 DNA samples in order to investigate by Sanger and Ultra Deep Sequencing the dynamics of decay and persistence of DNA HIV-1 variants harboring key drug resistance-associated mutations to NRTIs, in particular M184V, in patients with sustained virological control for at least 5 years under effective ART.

Measure: Percentage of M184V mutation Time: One measure per yearWeight gain following antiretroviral therapy (ART) initiation occurs with all modern regimens. Recent real-world reports suggest that integrase strand transfer inhibitor (INSTI)-based ART may be associated with excess weight gain compared to other regimens. Weight gain appears to occur regardless of baseline weight, and is most pronounced among women and minorities, often those at highest risk of obesity-associated comorbidities. INSTI- and TAF-based regimens are now preferred regimens for most persons according to the Department of Health and Human Services ART-Treatment Guidelines. As a result, there is an urgent need to understand the underlying mechanisms for this weight gain. This study aims to understand the changes in energy balance that occur with changes in ART. Participants with HIV who have experienced >10% weight gain on INSTI (bictegravir or dolutegravir-based therapy) will be switched to doravirine for 12 weeks, and then back to their prior INSTI regimen, allowing for assessment of changes in metabolic parameters with drug withdrawal and reintroduction (with no change to NRTI-backbone). Twenty-four hour energy balance will be measured on both regimens during a 24-hour stay using a whole room indirect calorimetry, with a standardized diet. Ultimately, the investigator's goal is to understand the mechanisms of weight gain so that future interventions can most effectively mitigate ART-associated weight changes.
