A Study of the Pharmacology of Oseltamivir (Tamiflu) in Pregnancy

Status Withdrawn

Clinical Trial Summary

The primary research question of this study is: Does the pharmacokinetics of oseltamivir after a single oral dose differ between the pregnant and non-pregnant women?

Clinical Trial Description

With the pending threat of pandemic avian influenza, the disproportionate morbidity and mortality documented in previous 20th century pandemics among pregnant women, and the lack of any data for use of these vital antiviral drugs in pregnancy, study of the pharmacology of oseltamivir in pregnancy is imperative. If and when the next pandemic occurs, a better understanding of this drug's safety and pharmacologic profiles for use in pregnancy is critical given the fact that it will be used in this vulnerable patient population.

This is a pilot study of the use of oseltamivir in pregnancy. This data will be combined with data from the parallel Pediatric Pharmacology Research Unit (PPRU) studies to put together a portfolio for use in understudied populations. This will allow for a re-thinking of the current status and potentially allow for small trials to be performed with patients who are suffering from influenza in pregnancy, to assess efficacy. The relevance with the pandemic strain and its corresponding Minimum Inhibitory Concentration (MIC) may have direct implications for dosing in pregnancy if lower levels of drug are documented. In addition, depending on the findings from the esterase component of the investigation, future investigation into mechanistic bases for changes in enzyme activity are possible. ;
