Filter by:The purpose of the protocol is to assess long-term safety and tolerability of subjects who discontinue for any reason from UK-453,061 qualifying studies.
This is a 96 week study to determine if UK- 453,061 in combination with Darunavir /ritonavir and a Nucleos(t)ide Reverse Transcriptase inhibitor is as efficacious, safe and tolerable as etravirine in combination with Darunavir /ritonavir and a Nucleos(t)ide Reverse Transcriptase inhibitor in HIV-1 infected patients who have been previously treated with antiretroviral drugs and have NNRTI resistance mutations.
The purpose of this study is to evaluate how much and how fast a single, oral, daily 25 mg dose of TMC278 is absorbed into the body when administered as a solution, suspension, granules, or a tablet. In addition, the effect of each formulation of TMC278 will be evaluated in patients in the fasted and fed states and the palatability (how the drug tastes) of each formulation will be assessed. Finally, the safety and tolerability of each formulation of TMC278 will be assessed throughout the study.
The presence of a pool of cells latently infected by HIV-1 in patients taking HAART and with a viral load below 50 copies/mL is the main limitation to eradication of the virus from the body. This viral reservoir prevents antiretroviral therapy from being interrupted; therefore, patients are obliged to continue with treatment for a period calculated to be greater than 60 years. Despite the important advances in knowledge of the biology of this reservoir, we still have no real knowledge about its dynamics. The opportunity to carry out a clinical trial for the first time with an integrase inhibitor is exceptional, since the results could provide important information on the nature of this reservoir. If maintenance of the reservoir is a dynamic process, inclusion of an integrase inhibitor is expected to lead to a reduction in the size of this reservoir. This effect could be critical when including IAT (viral reactivation), since, in theory, it would be necessary to act on a smaller reservoir. Current consensus is that it would be necessary to act on almost 100% of the viral reservoir (approximately 1,000,000 cells). The study has also been designed to enable us to understand the biochemical and molecular mechanisms by which certain drugs can induce viral reactivation in vitro as a previous step to a clinical trial aimed at reactivating viral latency and eradicating HIV-1 from the body.
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 (<) 18 years.

Despite the important advances in knowledge of the biology of this reservoir, we still have no real knowledge about its dynamics. The opportunity to carry out a clinical trial for the first time with CCR5 coreceptor antagonists is exceptional, since the results could provide important information on the nature of this reservoir. If maintenance of the reservoir is a dynamic process, inclusion of CCR5 inhibitors is expected to lead to a reduction in the size of this reservoir.

This study investigated whether human immunodeficiency virus type 1 (HIV-1) infected subjects with raised cholesterol switching their nucleoside reverse transcriptase inhibitor (NRTI) backbone from Kivexa (Epzicom) to Truvada had an improvement in their fasting total cholesterol after 12 weeks of treatment. The study also investigated whether any improvement had a beneficial effect on the overall cardiovascular risk.
The purpose of this study is: to determine the safety, (local) tolerability and plasma exposure over time of single intramuscular (IM) doses of 600 and 1200 mg of a new formulation (F006) of TMC278LA, to determine the safety, (local) tolerability and long-term plasma exposure over time of 2 dose regimens of 4 monthly IM doses of a new formulation (F006) of TMC278LA., To determine the safety, (local) tolerability and long-term plasma exposure over time of 1 dose regimen of 4 monthly subcutaneous (SC) doses of a new formulation (F006) of TMC278LA.
The purpose of this study is to determine the safety and antiviral activity of etravirine in treatment-experienced human immunodeficiency virus (HIV) infected children and adolescents.
The purpose of this trial is to compare the effectiveness, safety and tolerability of TMC278 given at a dose of 25 mg once daily versus efavirenz (EFV) at a dose of 600 mg once daily, when combined with a background regimen containing 2 nucleoside/nucleotide reverse transcriptase inhibitors ( investigator choice of ABC/3TC, TDF/FTC or AZT/3TC) in HIV-1 infected patients who have not yet taken any anti-HIV drugs. The following evaluations will be done: antiviral activity, immunologic changes, and viral geno-/phenotype evolution, relationship of Pharmacokinetics (PK) and PK/Pharmacodynamics and Medical resource utilization and treatment adherence.
