Active clinical trials for "Chagas Disease"

This randomized, blind, parallel-group trial will evaluate the efficacy and safety of Nifurtimox (NFX) and Benznidazole (BZN), the two usual interventions to treat the parasite Trypanosoma cruzi. The investigators will test whether NFX is an effective trypanocidal agent (by comparison with placebo) and equivalent to BZN (as active comparator) in terms of both parasite-related and safety outcomes. Individuals found seropositive and without clinical signs of dilated cardiomyopathy will receive either of the active treatments or matching placebo. Participants allocated to NFX or BZN will receive either a 60-day (full-dose) or a 120-day (half-dose) active treatment, whereas the control group will receive placebo for 120 days. There will be thus four arms of active treatment (NFX60, NFX120, BZN60 and BZN120), and a fifth control arm receiving placebo (1:1:1:1:1 allocation ratio) where every participant in the trial will take 120 days of study drug (the groups receiving full-dose will complete a 120-day masked treatment with placebo). The study plans to enroll 500 participants from Colombia (in two different geographical areas) and Argentina, in order to explore regional differences in the treatment effects.

This study will assess the safety and efficacy of E1224, a pro-drug of ravuconazole, in individuals with chronic indeterminate Chagas disease recruited in research centres in Tarija and Cochabamba, Bolivia.

The purpose of this study is to analyze the efficacy of syndecan-4 as a biomarker on the Chagas Disease prognosis. This analysis will be done through the correlation between the plasmatic levels of this molecule with functional and laboratory tests.

The purpose of this study is to analyze the efficacy of MicroRNAs as biomarkers on the Chagas Disease prognosis. This analysis will be done through the correlation between the plasmatic levels of this molecule with functional and laboratory tests.

The investigators propose to study the transfer of benznidazole into breastmilk from the blood of lactating women who receive the drug for the treatment of Chagas disease. Breastmilk and blood samples will be obtained from these patients at given times after they take the clinically indicated medication, and the concentrations in both matrices will be compared to estimate degree of transfer, which in turn will be used to evaluate potential degree of exposure of infants breastfed by these women. This study will help clarify safety of continuing breastfeeding while receiving treatment with benznidazole for Chagas disease.

Chagas disease is endemic to Latin America, and is of emerging importance in non-endemic countries because migration of people infected with T. cruzi. Current methods for diagnosis of T. cruzi infection are not ideal. Existing drugs for treatment are very limited, produce severe side-effects, and their effectiveness cannot be properly evaluated. Reliable biomarkers for prognosis, early diagnosis and effectiveness of treatment will be investigated.

The investigators propose to study the transfer of nifurtimox into breastmilk of lactating women who receive the drug for the treatment of Chagas disease. Breastmilk and blood samples will be obtained from these patients at pre-specified times after they take the clinically indicated medication, and the concentrations in both matrices will be compared to estimate degree of transfer. Estimation of nifurtimox transfer into breastmilk will allow the evaluation of potential degree of exposure of infants breastfed by these women to nifurtimox. This study will help clarify safety of continuing breastfeeding while receiving treatment with nifurtimox for Chagas disease.

The purpose of this study is to analyze the efficacy of Galectin-3 as a biomarker on the Chagas Disease prognosis. This analysis will be done through the correlation between the plasmatic levels of this molecule with functional and laboratory tests.

This study will evaluate the applications of ganglionar electrical stimulation in patients with Chagas Disease and Ischemic Heart Failure patients.

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.
