All Clinical Trials for EMTRICITABINE, RILPIVIRINE AND TENOFOVIR DISOPROXIL FUMARATE

Trial ID Title Status Sponsor Phase Start Date Summary
NCT00799864 ↗ A Study to Evaluate the Pharmacokinetics, Safety, Tolerability, and Antiviral Activity of Rilpivirine (TMC278) in Human Immunodeficiency Virus Infected Adolescents and Children Aged Greater Than or Equal to 6 Years Recruiting Janssen Sciences Ireland UC Phase 2 2011-01-07 The purpose of this study is to evaluate the pharmacokinetics, safety and antiviral activity of rilpivirine (TMC278) 25 milligram (mg) or adjusted dose once daily in combination with an investigator-selected background regimen containing 2 nucleoside/nucleotide reverse transcriptase inhibitors (N[t]RTIs) (zidovudine [AZT], abacavir [ABC], or tenofovir disoproxil fumarate [TDF] in combination with lamivudine [3TC] or emtricitabine [FTC] in antiretroviral (ARV) treatment-naïve adolescents and children aged greater than or equal to (>=) 6 to less than (
NCT01252940 ↗ Study to Evaluate Switching From Regimens Consisting of a Ritonavir-boosted Protease Inhibitor (PI) and Two Nucleoside Reverse Transcriptase Inhibitors (NRTIs) to a Fixed-dose Tablet Containing Emtricitabine/Rilpivirine/Tenofovir DF Completed Gilead Sciences Phase 3 2010-11-01 The purpose of this randomized, open-label, multicenter, active-controlled Phase 3b study is to evaluate the noninferiority of the emtricitabine/rilpivirine/tenofovir disoproxil fumarate (FTC/RPV/TDF) single-tablet regimen (STR; also referred to as fixed-dose regimen or fixed-dose tablet) relative to regimens consisting of a ritonavir-boosted protease inhibitor (PI+RTV) and two nucleoside reverse transcriptase inhibitors (NRTIs) in virologically suppressed, HIV-1 infected subjects. The FTC/RPV/TDF STR could offer an attractive treatment option to patients who wish to simplify dosing by reducing pill burden or to improve the tolerability of their treatment. Participants will be randomized into 2 groups, the FTC/RPV/TDF STR group, in which participants will switch treatment regimens at the start of the study, and the Stay on Baseline Regimen (SBR)/Delayed Switch group, in which participants will remain on their baseline regimen during the first 24 weeks of the study (designed to provide an initial active control), and may switch to the FTC/RPV/TDF STR at the Week 24 visit. After the 48-week study analysis period, participants may continue to receive the FTC/RPV/TDF STR per protocol before switching to a commercially available source.
NCT01286740 ↗ Study to Evaluate Switching From a Regimen Consisting of the Efavirenz/Emtricitabine/Tenofovir Disoproxil Fumarate Single-Tablet Regimen (STR) to the Emtricitabine/Rilpivirine/Tenofovir Disoproxil Fumarate STR Completed Gilead Sciences Phase 2 2011-01-01 The purpose of this Phase 2b study was to evaluate the efficacy and safety of the emtricitabine/rilpivirine/tenofovir disoproxil fumarate (FTC/RPV/TDF) STR, after switching from the efavirenz (EFV)/FTC/TDF STR at baseline, in maintaining HIV-1 RNA < 50 copies/mL at Week 12. HIV-infected patients were enrolled if they had received EFV/FTC/TDF for ≥ 3 months prior to study start, were experiencing safety or tolerability concerns (in particular, EFV-related intolerance), and wished to change to an alternate, better-tolerated regimen.
NCT01309243 ↗ Study to Evaluate the Safety and Efficacy of a Single Tablet Regimen of Emtricitabine/Rilpivirine/Tenofovir Disoproxil Fumarate Compared With a Single Tablet Regimen of Efavirenz/Emtricitabine/Tenofovir Disoproxil Fumarate in HIV-1 Infected, Antiret Completed Gilead Sciences Phase 3 2011-02-01 The purpose of the study was to evaluate the safety and efficacy of the emtricitabine (FTC)/rilpivirine (RPV)/tenofovir disoproxil fumarate (TDF) single-tablet regimen (STR) compared with the efavirenz (EFV)/FTC/TDF STR in HIV-1 infected adults who had not previously received treatment with antiretroviral medications. Participants were randomized in a 1:1 ratio to receive one of the study treatments. Randomization was stratified by HIV-1 RNA level (≤ 100,000 copies/mL or > 100,000 copies/mL) at screening. A treatment duration of 96 weeks was planned, with the option for subjects in FTC/RPV/TDF STR arm to receive treatment following the Week 96 visit until FTC/RPV/TDF STR is commercially available or until Gilead Sciences elects to terminate development in that country.
NCT01500616 ↗ Telaprevir Open-Label Study in Co-Infected Patients Completed Janssen-Cilag International NV Phase 3 2012-06-01 The purpose of this study is to collect safety and tolerability data on telaprevir treatment in combination with Peg-IFN-alfa and RBV in patients with HIV/genotype 1 chronic HCV coinfection with severe fibrosis or compensated cirrhosis who are not eligible for enrollment into an ongoing clinical study of telaprevir.
NCT01709084 ↗ A Clinical Trial Comparing the Efficacy of Tenofovir Disoproxil Fumarate/Emtricitabine/Rilpivirine (TDF/FTC/RPV) Versus TDF/FTC/Efavirenz (TDF/FTC/EFV) in Patients With Undetectable Plasma HIV-1 RNA on Current First-line Treatment Completed Janssen-Cilag International NV Phase 3 2013-10-02 The purpose of this study is to demonstrate noninferiority (a new treatment is equivalent to standard treatment) in terms of the percentage of patients who have plasma human immunodeficiency virus-type 1 (HIV-1) ribonucleic acid (RNA) levels less than 400 copies per mL after 48 weeks of randomized treatment with tenofovir disoproxil fumarate/emtricitabine/rilpivirine (TDF/FTC/RPV) versus TDF/FTC/efavirenz (TDF/FTC/EFV).
NCT01777997 ↗ FTC/RPV/TDF on T-Cell Activation, CD4+ T-Cell Count, Inflammatory Biomarkers and Viral Reservoir Completed National Institute of Allergy and Infectious Diseases (NIAID) Phase 4 2013-04-25 This study was done with people who were infected with HIV, but did not show any signs of having HIV. They were also feeling well without taking HIV medication and had low or undetectable levels of the virus in the blood. The purpose of this study was to see if taking HIV medication (antiretroviral therapy [ART]) would reduce immune activation (a signal that the body is fighting an infection) in people who have HIV, but did not show symptoms. Also this study helped determine how safe the drug was and how well people reacted to the drug. For this study, the following antiretroviral therapy (ART) was be provided in the form of a single tablet that contains three different drugs: emtricitabine/rilpivirine/tenofovir disoproxil fumarate (FTC/RPV/TDF). These drugs were combined as one tablet which was approved by the Food and Drug Administration (FDA) as a single pill to treat HIV infection. The HIV medication provided was one of the recommended treatments for HIV, including people with low viral loads (how much HIV you have in your body) who were taking HIV drugs for the first time. The risks seen with this HIV medication were the same that one would encounter when taking these drugs outside of the study.
