Since our last POST was released, there have been a number of exciting developments at the Pediatric Trials Network (PTN). In addition to enrolling patients in several studies, including long-term antipsychotic use and commonly used drugs passed through breast milk, PTN research has helped inform a drug label change for acyclovir and a fluconazole update published in Red Book. In this POST issue, you will also find information regarding the LAPS Trial and the upcoming Pediatric Academic Societies (PAS) Meeting, as well as a spotlight on Dr. Christine Turley, who has been heavily involved in the PTN POPS study. We are thankful to everyone involved in the PTN. The hard work of many enables us to continue our mission of informing formulation, dosing, efficacy, and safety of drugs, as well as medical devices, used in pediatric patients. We look forward to an exciting and productive 2019!
