Despite increased regulatory support for pediatric drug development, sponsors still face ethical, economic and practical constraints. Indeed, while children represent about 40% of the world’s population, only 10% of the drugs on the market have been approved for pediatrics. Children are not small adults, and all children are not the same. In particular, children under […]Read More

Given the ubiquity of pregnancy and births, you’d think that there would be a robust understanding of the safety and efficacy of drugs in pregnant women. However, the vast majority of drugs are prescribed to pregnant women off-label— often scaling doses from the recommendations set for men or non-pregnant women— because of ethical concerns about performing clinical testing in this vulnerable population.
Physiological and absorption, distribution, metabolism, and excretion (ADME) changes during pregnancy can significantly affect pharmacokinetics (PK). This can lead to under-dosing, with lack of therapeutic effect, or over-dosing, with potential toxicity that endangers both mother and developing fetus. In this blog post, I’ll discuss how pharmacometrics and modeling approaches can be leveraged to identify drugs whose PK may be altered during pregnancy, guide rational study design, and support dosing recommendations for pregnant women.Read More
