Active clinical trials for "Acquired Immunodeficiency Syndrome"

Purpose: This is a pilot study to evaluate HIV viremia and persistence in acutely HIV infected antiretroviral naïve patients treated with Darunavir/ritonavir and Etravirine Participants: 20 participants, age 18 and older, HIV infected, antiretroviral naïve patients Procedures (methods): ARV treatment with Darunavir/ritonavir and Etravirine, Optional studies: Genital secretion samples, Cerebrospinal fluid samples, Leukapheresis, Endoscopy/colonoscopy

Apricitabine is a new NRTI which is active against drug-resistant HIV. NRTIs are often included as part of patients' treatment, but many HIV-infected patients develop resistance to commonly used NRTIs such as lamivudine (3TC) and emtricitabine (FTC). This study will examine whether including apricitabine as part of patients' treatment is more effective than including lamivudine,when patients change treatment because of drug resistance.

The study will compare the safety and efficacy of an investigation nucleoside analog reverse transcriptase inhibitor (NRTI), dexelvucitabine (DFC), to an approved NRTI, lamivudine (3TC) in HIV treatment-experienced patients who are resistant to 3 classes of antiretroviral therapies (NRTIs, PIs and NNRTIs). Patients meeting eligibility requirements will have a new 'optimized' background regimen (OBR) selected for them by their investigator based on prior ARV treatment history and the results of HIV genotype and phenotype tests performed during the screening period. In addition to treatment with the new OBR, patients will be randomized to receive treatment with either DFC or 3TC in a blinded fashion. There is a 50 percent chance a patient will receive DFC or 3TC. Treatment in the study may continue for up to 96 weeks. Patients with an inadequate response to therapy after 16 weeks will have the option to change their OBR and the option to switch to receive the other study medication (i.e., DFC to 3TC or 3TC to DFC).

This study is a 96-week study designed to evaluate the safety and efficacy of GW873140 in combination with Kaletra in HIV infected, untreated subjects.

The objectives of this data collection activity are to: Describe the baseline demographics, clinical and laboratory profile of patients who ever received darunavir (DRV) and/or etravirine (ETR), at the time of initiation on DRV and/or ETR; Describe the clinical and laboratory profile of patients who ever received DRV and/or ETR every 6 months from the first data collection point through 2021; Describe dynamics in HIV drug resistance mutations among patients who fail treatment on new regimens including DRV and/or ETR; Describe demographics, clinical and laboratory profile of young adults who transition out of the donation program after the age of 25 years at 12 months after their transition.

This is a clinical trial for TPLWH (Trans People Living with HIV) who are stable on cART with an undetectable viral load or a detectable viral load but no resistance to NRTIs and InSTI. Following written consent and screening procedures, study subjects will undergo a switch (or will restart) of their combination antiretroviral therapy (cART) to Biktarvy. The goal of this research project is to recruit an understudied population into a controlled clinical trial aimed at optimizing TPLWH cART. This will be demonstrated by measuring viral load outcomes at regular intervals, with a focus on viral load results 48 weeks after Biktarvy initiation (primary outcome).

HIV related cognitive impairment still occurs despite highly active antiretroviral therapy (HAART). HIV disease affects the brain in 20-40% of patients with advancing HIV disease leading to varying degrees of cognitive impairment, recently termed HIV associated neurocognitive disorders (HAND). HAND may occur in patients who are virally suppressed in both blood and CSF. Patients with HIV Associated Neurological Disorders (HAND) who are virally suppressed in both their blood and cerebrospinal fluid (CSF), whilst on a highly active antiretroviral therapy (HAART) regimen may have significant cognitive improvement with HAART intensification with the medication Raltegravir; compared to those who remain on their existing regimen. This study will be a prospective, interventional, randomised and unblinded controlled clinical trial. The aim of this study will be to determine whether HAART intensification with the medication Raltegravir, leads to significant improvement in HIV associated neurological disorders (HAND). Patients with the recent progression (within 6 months) of HAND (validated by neuropsychological assessment) on HAART who are virally suppressed (<50 copies per ml) in blood and CSF will be randomised to have their existing HAART regimen intensified with raltegravir 400mg twice daily, or not. The control arm will remain on their medication regimen as prescribed. The target is to enrol 110 patients into the control group, and 110 patients into the Raltegravir intensification group. Patients will undergo baseline neuropsychological testing, MRI, blood tests, and cerebral spinal fluid (CSF) tests (via a lumbar puncture). The methods used to determine the effectiveness of adding Raltegravir, will include further neuropsychological testing at 6 months; and neuropsychological testing, MRI and CSF assessment at 12 months. Neuropsychological testing completed at 6 and 12 months will be completed by a "blind assessor", in that they will have no knowledge of which arm (treatment or control) the participant is enrolled in. An evaluation (neuropsychological testing) will be performed should the patient deteriorate during the course of the study, as recognised by the patient's managing physician. The decision of the Antiretroviral medication regimen to be used in such a case will be determined by the managing physician. At the end of the study protocol (12 months) the patient's HAART therapy will be managed by their primary physician.

This phase I trial studies the side effects and best dose of erlotinib hydrochloride in treating non-small cell lung cancer that has spread to other parts of the body or cannot be removed by surgery in patients with human immunodeficiency virus (HIV) infection. Erlotinib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Erlotinib hydrochloride is a standard drug used for treating lung cancer, however, it is not yet known whether it is safe to give erlotinib hydrochloride to patients who also have HIV infection or not.

This study is a 96-week study designed to evaluate the safety and efficacy of GW873140 in combination with Combivir in HIV infected, untreated subjects.

This is a two phase study (randomised and non-randomised phase). The randomised phase will initially examine 4 blinded doses of GW640385 boosted with rtv (with continuation of current background therapy) in comparison to an ongoing, open-labeled rtv-boosted protease inhibitor (PI) regimen for 15 days. At the Day 15 visit, all subjects will optimize background therapy. Additionally, subjects receiving the lowest dose of GW640385 will be re-randomised to one of the higher doses and subjects in the control arm will receive a new rtv-boosted PI based on resistance testing at screening. Subjects will remain in the randomized phase on one of these 4 continuing treatment arms for at least 48 weeks. An interim analysis will occur during the randomised phase to select for a dose of GW640385 to evaluate further in Phase III studies. After dose selection subjects will move to the non-randomised phase of the study. In the non-randomised phase subjects who are receiving GW640385 will be assigned to final selected dose for assessment of long term safety, tolerability, pharmacokinetics, and antiviral activity.
