Official Title

Observational Pregnancy Safety Study of Women Exposed to Nifurtimox During Pregnancy to Describe the Risk of Pregnancy and Maternal Complications and Other Events of Interest on the Developing Fetus, Neonate, and Infant

Brief Summary

      This is an observational study in which data from women with Chagas disease who will take or
      have already taken nifurtimox during pregnancy and the impact on their babies are studied.

      Chagas disease is an inflammatory, infectious disease caused by the parasite Trypanosoma
      cruzi. This parasite is mainly spread by insects called triatomine bug. If Chagas disease is
      left untreated, it can later cause e.g. serious heart and digestive problems.

      Nifurtimox has been used for more than 50 years to treat Chagas disease in children and
      adults.

      It is not recommended to be used during pregnancy as data from animal studies indicate that
      it may harm the baby. Currently, there are not enough data to know if this is also the case
      in humans.

      In this study, researchers want to collect data on the safety of nifurtimox use in pregnant
      women. To do this, researchers will collect the following information:

        -  Birth defects (abnormal and problematic structures or functions, a child is born with)

        -  Pregnancy outcomes (like live birth, preterm birth, still birth/death of the unborn
           baby, miscarriage, or abortion)

        -  Certain health problems of the child up to 12 months of age

        -  Certain health problems of the women experienced during pregnancy The data will be
           collected from different sources including telephone calls with the women or their
           doctor, CRFs (case reprt forms) or from medical records The researchers will compare the
           proportion of children with birth defects, pregnancy outcomes or certain health problems
           of the child or the women during pregnancy with available data on these outcomes in the
           general population.

      The study will run for approximately 10 years.
