Pharmacokinetics of Primaquine in Lactating Women - Towards Equitable Radical Cure of Vivax Malaria

Brioni Moore of Curtin University in Australia will perform a trial in Papua New Guinea to validate minimal transfer through breastmilk of the antimalarials primaquine and tafenoquine to enable access by postpartum women to radical malaria cure. Verifying minimal drug transfer in the first two weeks post-birth would enable maternal treatment before hospital discharge, preventing postpartum relapses and improving maternal health outcomes and malaria control. They will recruit a cohort of mother-child pairs in which the mother has confirmed vivax malaria or a recent history of it. They will then quantify the excretion of primaquine and tafenoquine in colostrum and transitional breast milk and determine relative infant exposure, while assessing indices of neonatal physiology.
