Primary Outcome Measures:
  • Superiority of nifurtimox to historical untreated control in children: Sero-conversion for subjects ≤ 8 months of age at randomization [ Time Frame: 360 days from end of treatment [EOT] ]
    Sero-conversion: defined as negative antibody concentration to Trypanosoma cruzi Binary variables: CURE (negative ELISA result) / NO CURE (positive ELISA result)

  • Superiorty of nifurtimox to historical untreated control in children: Sero-reduction for subjects ≥ 8 months to <18 years of age [ Time Frame: 360 days from end of treatment [EOT] ]
    Sero-reduction:defined as Recombinant ELISA (enzyme-linked immune sorbent assay) serology tests based upon a target of ≥ 20% decrease in antibody concentration to Trypanosoma cruzi Binary variables: CURE (20% or more reduction in antibody) / NO CURE ( less than 20% reduction in antibody)


Secondary Outcome Measures:
  • Comparability of a 60-day regimen of nifurtimox to historical active control (benznidazole) as sero-reduction or sero-conversion [ Time Frame: up to 420 days (Visit 11) post-treatment ]
    Binary variables : CURE (negative ELISA result or ≥ 20% reduction in antibody concentration) / NO CURE (positive ELISA result or less than 20% reduction in antibody).

  • Comparability of a 30-day regimen of nifurtimox to a 60-day regimen of nifurtimox as sero-reduction or sero-conversion and to qualitative polymerase chain reaction (qPCR) [ Time Frame: up to 420 days (Visit 11) post-treatment ]
    Binary variables :CURE (negative ELISA result , ≥20% reduction in antibody concentration, or non-reactive PCR test) / NO CURE (positive ELISA result , less than 20% reduction in antibody, or , reactive PCR test).

  • Relationship of conventional serology (as sero-reduction or sero-conversion) to qPCR using frequencies of matches and mismatches to assess agreement [ Time Frame: up to 420 days (Visit 11) post-treatment ]
    Comparison of CURE / NO CURE results for ELISA tests and PCR tests.

  • Relationship of non-conventional serology to conventional serology [ Time Frame: up to 420 days (Visit 11) post-treatment ]
    Compare CURE / NO CURE results for non-conventional ELISA and conventional ELISA tests.

  • Safety/tolerability profile of nifurtimox by assessing the number of participants with Adverse Event as a measure of safety and tolerability [ Time Frame: up to 420 days (Visit 11) post-treatment ]
  • Safety/tolerability profile of nifurtimox by laboratory parameters [ Time Frame: up to 420 days (Visit 11) post-treatment ]
    Hematology Blood chemistry Urinalysis

  • Safety/tolerability profile of nifurtimox by electrocardiogram (ECG) monitoring [ Time Frame: up to 420 days (Visit 11) post-treatment ]
  • Safety/tolerability profile of nifurtimox by laboratory parameters vital sign measurements [ Time Frame: up to 420 days (Visit 11) post-treatment ]
    Blood pressure Heart rate Respiratory rate Temperature

  • Safety/tolerability profile of nifurtimox by physical examinations [ Time Frame: up to 420 days (Visit 11) post-treatment ]
    Neurological examinations

  • Pharmacokinetics - Plasma concentration time courses in children: maximum concentration (Cmax) of nifurtimox, after first dose and at steady state [ Time Frame: up to 60 days (Visit 8) ]
  • Pharmacokinetics - Plasma concentration time courses in children: time to maximum plasma concentration (Tmax) of nifurtimox, after first dose and at steady state [ Time Frame: up to 60 days (Visit 8) ]
  • Pharmacokinetics - Plasma concentration time courses in children: Area under the curve (AUC), regarding plasma nifurtimox concentration-time curve after first dose and at steady state [ Time Frame: up to 60 days (Visit 8) ]
  • Pharmacokinetics - Plasma concentration time courses in children: Half-life (t1/2) of nifurtimox, after first dose and at steady state [ Time Frame: up to 60 days (Visit 8) ]
