Study of Benznidazole Transfer Into Breastmilk in Lactating Women With Chagas Disease

NCT01547533 | Completed DMC

• 1 other identifier: LACT-BENZNIDAZOLE
• Study Type: observational

Brief Summary

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.

Conditions

Chagas Disease; Lactation

Keywords

Chagas disease; lactation; breastmilk; postpartum period; infants; pediatric clinical pharmacology; developmental clinical pharmacology; parasitology; trypanosoma cruzi

Outcome Measures

Primary Outcomes (1)

• Benznidazole concentration in breastmilk and in plasma

  Randomly obtained breastmilk samples will be obtained to both evaluate the breastmilk / plasma concentration ratio of the drug, and to develop a population pharmacokinetics model of drug trasfer into breastmilk, if possible. Breastmilk concentrations will be used to calculate potential infant exposure through breastmilk to the medication (benznidazole) taken by the mother

  at randomly selected time points during the 30 days of treatment

Secondary Outcomes (1)

• incidence of adverse drug reactions in women treated with benznidazole during lactation

  throughout the 30 days of treatment

Study Arms (1)

Eligibility Criteria

• Age: 18 Years - 40 Years
• Sex: female
• Healthy Volunteers: No
