Filter by:This study evaluate the efficacy and safety of benznidazole in the treatment of chronic indeterminate Chagas disease in children. All subjects will receive benznidazole and results will be compared to historically to a placebo arm.
The purpose of this study is to evaluate the effect of sacubitril/valsartan 200 mg BID compared with enalapril 10 mg BID, in addition to conventional heart failure (HF) treatment, in improving a hierarchical composite of cardiovascular (CV) events (i.e. CV death or the occurrence of first HF hospitalization) and causing a greater reduction in n terminal prohormone of brain natriuretic peptide (NT-proBNP, at Week 12 from Baseline) in participants with HF with reduced ejection fraction (HFrEF) caused by CCC.
Chagas disease (CD) is an endemic zoonotic disease with a significant global impact. Current approved treatments for CD (benznidazole (BZN) and nifurtimox (NFX)) were developed in the 1970s with regimens and dosing intervals derived from decades-old patient series and with very limited direct comparisons. Treatment recommendations vary significantly from country to country and the comparative evidence-base with the current treatment regimens is limited. The reported efficacy of both drugs in patients with T. cruzi infection is variable and depends on the disease stage, the drug dose, the age of patients, and the infecting T. cruzi strain or genotype. Due to a therapeutic failure of at least 20% after 12 months in chronic patients and the high rate of adverse events, together with the recent data that suggest that we may be overdosing patients, we propose to test new dosing regimens of these two old compounds. Hypotheses: - Lowering the frequency of drug dosing of BZN and NFX, the plasma drug levels of the drugs within the therapeutic range will be maintained. - The duration of treatment with BZN or NFX may be related to the effectiveness of these drugs. - Blood levels of the proposed biomarkers will significantly diminish or became negative after a relatively short interval after treatment.
The purpose of this study is to determine whether benznidazole and E1224 should be administered concomitantly in patients with Chagas Disease as not enough data are available. This study aims to assess cross interactions of these two compounds.
The researchers in this trial want to analyze prerecorded patient data which provide information on benefits of the drug nifurtimox in patients with a sudden (acute) and long lasting (chronic) Chagas´ disease an illness caused by parasites mostly transmitted to humans by a bug. They also want to learn how often organs, especially the heart, are affected by the illness in treated and untreated chronic Chaga's patients. In order to find this out medical records of adult and pediatric patients in Argentina will be analyzed.
This study evaluate the addition of colchicine in the treatment of patients with Chagas´disease. Forty patients will receive colchicine while twenty patients will receive placebo
The investigators are proposing to perform a double-blinded, non-inferiority randomized controlled trial comparing a short 30-day treatment with BZN 150mg/day (30d/150mg) vs. a 60-day treatment with BZN 300 mg/day (60d/300mg). The investigators will recruit not previously treated T. cruzi seropositive women with a live birth during the postpartum period in Argentina, randomize them at six months postpartum, and follow them up with the following specific aims: Specific Aim 1: To measure the effect of BZN 30d/150mg compared to 60d/300mg preconceptional treatment on parasitic load measured by the frequency of positive PCR (primary outcome) and by real-time quantitative PCR (qPCR), immediately (Specific Aim 1a) and 10 months (Specific Aim 1b) after treatment. Hypothesis 1a: The frequency of positive PCR and the parasitic load measured by qPCR immediately after BZN 30d/150mg will be non-inferior (Non Inferiority [NI] margin for PCR: 10% absolute difference) to BZN 60d/300mg. Hypothesis 1b: The frequency of positive PCR and the parasitic load measured by qPCR 10 months after BZN 30d/150mg will be non-inferior (NI margin for PCR: 9% absolute difference) to BZN 60d/300mg. Specific Aim 2: To measure the frequency of serious adverse events leading to treatment interruption of BZN 30d/150mg compared to 60d/300mg. Hypothesis 2: The frequency of serious adverse events leading to treatment interruption will be 50% lower with BZN 30d/150mg than with BZN 60d/300mg. A 24-month recruitment period is planned in four hospitals with 23,436 deliveries in 2015 and frequencies of T. cruzi seropositive women varying from 1.5% to 4.8%. The investigators are planning to enroll 600 T. cruzi seropositive women.
This study focuses on the evaluation of low doses (600 and 1200 mg) and short treatment duration (at 3, 7 and 10 days) of fexinidazole (Fexi) to determine the minimal efficacious and safe dose for the treatment of adult patients with chronic indeterminate Chagas Disease (CD).
The present study aims to evaluate the microvascular endothelial function of a single centre cohort of patients with the cardiac form of Chagas disease, and to search for associations with clinical and laboratory variables.
Recent scientific advances have provided further impetus to develop new therapeutic approaches for Chagas Disease (CD) using different doses and duration of BZN, as well as combinations directed at multiple therapeutic targets to improve treatment response and tolerability and reduce the potential for development of resistance. This project focuses on the proof-of-concept evaluation of improved treatment regimens of BZN, with the assessment of new BZN-sparing regimens in monotherapy and in combination with E1224.
