Benznidazole Evaluation for Interrupting Trypanosomiasis - The BENEFIT Trial

Descripción detallada

A randomized double-blind controlled clinical trial investigating the role of benznidazole in patients with chronic Chagas' heart disease. Chagas disease has 3 phases: acute, undetermined and chronic phases. There are no clinical trials up to date that have investigated the use of antiparasitic drugs in patients that are in the chronic phase. This study will evaluate the efficacy and safety of benznidazole (an antiparasitic drug) in patients with chronic Chagas' heart disease. Evaluate if benznidazole, an antiparasite drug, given at a dose calculated as 5mg/kg/day for 60 days, now administered as a fixed daily dose of 300mg during 40 to 80 days of treatment - period adjusted according to the patient's body weight to a total minimum dose of 12g (corresponding to 40kg) and a total maximum dose of 24g (corresponding to 80kg) - reduces morbidity and mortality in patients with Chronic Chagas' Cardiomyopathy (CCC). It will be developed in 49 study centres in Argentina, Bolivia,Brazil,Colombia, and El Salvador - countries with high incidence of Chagas Disease. The Pilot study is evaluating if benznidazole is effective in producing parasitic cure (PCR negativization or reducing parasitic load) in chronic Chagas Disease as well as assessing the feasibility of conducting a large trial in chronic Chagas Disease in South America.
