Official Title: Cardiovascular Health Investigation and Collaboration From Countries of America to Assess the Markers and Outcomes of Chagas Disease (CHICAMOCHA-3) - EQUITY (Equivalence o
Brief Summary:
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.
