abstract

  • BackgroundThe U.S. Food and Drug Administration implemented the new Pregnancy and Lactation Labeling Rule (PLLR) in June 2015. Under PLLR, all new drug applications were to present a narrative risk assessment (as opposed to letter category), while drug approvals after June 2001, were required to phase in by June 2020. The purpose of this study was to assess the quality of presented pregnancy and lactation data in the drug labeling and degree of adherence to the PLLR.Design/MethodsWe reviewed the labeling data of all new molecular entities (NMEs) approved from 1999–2017. The pregnancy and lactation information was classified as: 1. Harmful to use 2. Safe to use 3. Consideration of safety and efficacy. For drugs approvals after June 2001, presence of pregnancy letter category system was noted.ResultsOf the 456 NMEs, 131 (29%) were classified as harmful to use in pregnancy and 207 (45%) as harmful to use during lactation. This number did not follow any specific pattern over the course of 19 years. Less than 1% of drugs were deemed to be safe during pregnancy or lactation. Human data was the source of pregnancy or lactation information for only 2% of drugs. Up to 70% of drugs belonged to each implementation schedule has yet to meet the PLLR compliance requirement.Conclusion(s)Pregnant and lactating women are mostly advised against use of medications that might be needed for their health and health of their infants based on very limited data. Pharmaceutical companies lagged behind the required adherence rule for labeling updates on pregnancy and lactation information.Disclosure(s)Nothing to disclose
