New Dosage	NCT03981523 ↗	New Therapies and Biomarkers for Chagas Infection	Active, not recruiting	Barcelona Institute for Global Health	Phase 2	2019-12-18	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.
