NCT ID: NCT03327740 Active, not recruiting - Clinical trials for Infection, Human Immunodeficiency Virus I

PRJ2203: Dolutegravir Post Authorization Safety Study (PASS)

Start date: September 30, 2014
Phase: N/A
Study type: Observational

Dolutegravir (DTG) is recommended for both treatment-naïve and treatment-experienced, HIV infected adults and paediatric subjects aged 12 years and older and weighing at least 40 kg. One case of suspected DTG hypersensitivity (HSR) reaction from among over 1500 subjects exposed to the drug at the time of submission in 4Q2012, has been identified; this subject experienced a diffuse maculopapular rash with fever and elevated liver enzymes. Isolated rash was uncommon in the DTG programme with less than 1% of clinical trial subjects experiencing treatment related rash. The pharmacovigilance strategy for DTG and DTG-containing products is to implement a post-marketing risk management program to further quantify the risk of HSR and compare it to that of other integrase inhibitors, and to possibly determine associated risk factors. In addition, the post-authorization safety study will monitor and compare hepatotoxicity and severe skin rash following initiation of DTG or other integrase inhibitor (raltegravir (RAL) or elvitegravir (EGV) based antiretroviral regimens (ARV). Further to be able to distinguish the above symptoms and reactions caused by DTG or the other integrase inhibitor regimen from that of abacavir (ABC), known to cause hypersensitivity reaction, the integrase inhibitor groups will be compared in combinations with and without ABC. This five year-long safety study will be conducted through collaboration with EuroSIDA, a well established prospective observational cohort study of more than 18,200 subjects followed in 107 hospitals in 31 European countries, plus Israel and Argentina. This is a five year-long non-interventional prospective cohort study nested within the EuroSIDA study. The study population will include HIV positive subjects over the age of 16 years from EuroSIDA clinical sites, who are new users of DTG or other integrase inhibitors with and without ABC. Following initiation of DTG with ABC based antiretroviral regimen or DTG without ABC or regimens containing other integrase inhibitors (RAL, EGV) with or without ABC or any other DTG based ARV regimen as monotherapy or two-drug regimens, the study will aim to a) Monitor and compare hypersensitivity reaction, b) Monitor and compare hepatotoxicity, and c) Monitor and compare severe skin rash among all subjects discontinuing DTG or other integrase inhibitor regimens for any reason.

NCT ID: NCT03314064 Active, not recruiting - Clinical trials for Infection, Human Immunodeficiency Virus

Phase 4 Study of Dolutegravir (DTG) in Russian Federation

Start date: December 8, 2016
Phase: Phase 4
Study type: Interventional

DTG 50 milligram (mg) tablet was approved for marketing in Russian Federation; however, DTG is not currently available for subjects at Acquired Immune Deficiency Syndrome (AIDS) Centers as it is not available for order and supply via Federal program. This study is an open-label study which will include subjects, who complete taking DTG in studies ING112276, ING113086, ING114915, ING111762, and those subjects who end participation in study 200304 in which they received either DTG or lopinavir/ritonavir (LPV/RTV). DTG will be supplied at a dose of 50 mg once daily to eligible subjects until the subject stops taking DTG or transitions to commercial supply of DTG when available at AIDS Centers via the Federal program. The objective of this study is to bridge the gap between the closure of ING112276, ING113086, ING114915, ING111762 or end of subject's participation in 200304 and the actual availability of commercial DTG at AIDS Centers via Federal program for human immunodeficiency (HIV)-1-infected adult subjects in Russian Federation. The study will also investigate long-term safety of DTG for subjects continuing DTG in Russian Federation.

Pyridostigmine as Immunomodulator in People Living With HIV

Start date: October 1, 2017
Phase: Phase 2
Study type: Interventional

Human immunodeficiency virus (HIV) infection is a public health problem with enormous personal, and social losses. According to the National Mexican HIV/AIDS survey, more than 235,000 new cases of HIV infection were reported in Mexico between 1983 and 2015. HIV infection is characterized by persistent immune activation and constant turnover of T cells. This leads to a precipitous fall in the number of CD4 + and CD8 + T cells, as well as to an early immunosenescence phenomenon that conditions susceptibility to opportunistic infections and a profound decrease in circulating and mucosal T cells. In these patients, modulation of the immune response represents a promising mechanism to maintain immunological homeostasis and prevent the development of pathology. From this perspective, it is feasible that lesser immune activation - rather than accelerating the progression of infection - may be an important actor in controlling infection and delaying the progression from chronic infection to acquired immunodeficiency syndrome (AIDS) . The administration of highly active antiretroviral therapy (ART) has resulted in a reduction in the mortality of these patients, although the occurrence of late morbidity due to both infection and treatment has increased. Unfortunately, even in cluntries with complete coverage for HIV-infection, a large group of patients do not start treatment until late stages, in which immunosenescence is profound and the possibilities of immunological recovery (increase in T cell counts CD4 +, normalization of the CD4 + / CD8 + index, decrease in susceptibility to opportunists, normalization in the cellular response to vaccines) are very low. In this context, finding new immuno-modulatory strategies that are both easily applicable and potentially improving survival and quality of life is crucial. The therapeutic use of neuroimmune regulators in HIV infection has been poorly explored. In brief, the nervous system has evolutionary mechanisms of reflex control of the inflammatory response, such as cholinergic anti-inflammatory reflex (RCA). Cholinergic stimulation through the use of nicotinic agonists has shown promising effects in murine and cellular models of systemic inflammation. Since cholinergic agonists are rapidly degraded or cause side effects, we performed a pilot study using pyridostigmine (Mestinon®), an acetylcholinesterase inhibitor (ACh-E), in HIV-infected patients. We observed that administration of pyridostigmine decreases the activation and proliferation of HIV-infected T cells, reduces the production of interferon (IFN) -gamma and increases that of interleukin (IL) -10 (Valdés-Ferrer SI et al., AIDS Research And Human Retrovir 2009). In a second open-label pilot study in seven chronically infected patients with full virological suppression but without concomitant elevation of CD4+ T cell counts, we found that the addition of pyridostigmine to ART led to a sustained and significant increase in the number of CD4 + T cells (PRS record: NCT00518154; in preparation for publication). These results suggest that the addition of pyridostigmine to antiretroviral therapy may be beneficial in achieving and maintaining immunological homeostasis in patients with HIV. The present study will address the potential effectiveness of add-on pyridostigmine (90mg, once per day, per oris) on CD4+ T cell counts, CD4+/CD8+ ratio, as well as ex-vivo markers of T cell phenotype and activity. The study is designed as a 24-week crossover study where patients will start a 12-week of pyridostigmine or placebo, and then crossing-over for an aditional 12 weeks (placebo-to-pyridostigmine, and pyrodistigmine-to-placebo). Since pyridostigmine is a commonly used drug for both myasthenia gravis and as a preventive in biological warfare cases, if our hypotheses are correct, the results will be easily extended to clinical practice, as there is enough long-term evidence of utility and safety of the drug.

NCT ID: NCT03145753 Active, not recruiting - HIV Infection Clinical Trials

Education vs Education Plus Intervention in HIV/HCV Diagnosis (DRIVE 03)

Start date: November 18, 2016
Phase: N/A
Study type: Interventional

Objectives: A targeted HIV testing strategy (TTS) through an HIV risk of exposure and indicator conditions (RE&IC) questionnaire resulted in same rate of new HIV infection diagnosis (NHID), coverage and even reduced costs compared with a universal non targeted (Non TSS) HIV testing strategy in a prior study (DRIVE 01). To compare number of New HIV/HCV Infection Diagnoses (NHID HIV/HCV) and costs two HIV/HCV testing programs in the Primary Health Care: an educational and support only initiative to enhance HIV /HCV testing (EDSUP) or EDSUP plus a resourced external program (DRIVE 03). Methodology: Prospective, randomized 1:1, clustered, crossover study, in one Health Care Area of Madrid, Spain, comparing the implementation of two HIV testing programs, EDSUP only vs. EDSUP plus DRIVE 03 program in 4 Primary Care Centers (PCC´s). People randomized to EDSUP plus DRIVE 03 program, non HIV infected, between 18-65 years, attending to any of the 4 PCC´s, not previously included in the study will be offered to participate. HIV testing program will be evaluated by measuring absolute number of new diagnosed infections (NDI) HIV/HCV and costs. Other outcomes considered will be people assigned and offered to participate, number of HIV tests performed, coverage (HIV /HCV tests/assigned population ratio), and rate of NDI HIV/HCV per ‰ tests performed. Six months prior to randomization main outcome variables will be recorded in the 4 PPC´s. Before randomization, EDSUP will be equally implemented in the 4 PCC´s. After randomization, first six months, DRIVE 03 program will be implemented in 2 PCC´s and in the other 2 observation of interest variables will be conducted. After first 6 month study period, PCC´s will be crossover to the opposite arm of randomization. DRIVE 03 program will offer rapid HIV tests, and testing staff to conduct all study procedures. For NDI HIV/HCV, molecular epidemiology, delayed diagnosis, retention in care, HIV/HCV treatment and control/eradication will be also monitored.

NCT ID: NCT03066128 Active, not recruiting - Clinical trials for Chronic HIV Infection

Point-of-care Viral Load Testing to Enable Streamlined Care and Task Shifting for Chronic HIV Care

Start date: February 24, 2017
Phase: N/A
Study type: Interventional

Effective management of patients on antiretroviral therapy (ART) is essential to improve clinical outcomes and prevent HIV transmission, but monitoring life-long ART for over 15 million HIV-infected people has become a challenge, particularly in low- and middle-income countries (LMICs). As programs continue to focus on identifying HIV-infected people and starting ART at higher CD4 thresholds, HIV providers have been overburdened, which has resulted in falling retention rates. As ART coverage scales up to include millions more people, additional strain will be placed on HIV clinicians and laboratories to manage stable patients on chronic ART. Implementing point-of-care HIV VL testing to enable task shifting to nurses for chronic HIV care may help mitigate these burdens. Point-of-care Viral Load (VL) testing is intended to differentiate patients who are potentially failing on their ART, so that they can be referred to the next level of care for possible ART regiment change, from patients who are virally suppressed on ART and can be managed by nurses. The investigator's scientific objective is to test the clinical equivalence and reduced cost of implementing a model for chronic HIV care that uses a point-of-care HIV VL assay to enable streamlined care and task shifting among healthcare workers at an urban clinic in South Africa. The central hypothesis is that rapid HIV VL testing, implemented by nurses, is an effective and cost-efficient strategy for management of chronic HIV infection in the majority of patients, thereby allowing more resources to be directed at the minority of patients who need greater attention. This work is innovative because it uses a randomized evaluation of an implementation model that combines a novel diagnostic point-of-care test with streamlined care and task shifting among healthcare workers compared to standard of care for chronic HIV care in a resource-limited setting. This randomized trial will then form the basis of a larger, multicountry proposal to demonstrate the clinical equivalence and cost-effectiveness of implementing an integrated point-of-care HIV VL testing and streamlined care model for chronic HIV care in LMICs. If nurses using clinic-based HIV VL testing are cost-effective for achieving both viral suppression and retention in care among patients on ART, then implementation of this chronic HIV care model would alleviate the strain on existing HIV providers and laboratories in LMICs.
