# Points to Consider on the Use of Medicines in Pregnancy Throughout the Product Lifecycle Based on Global Regulatory Guidance

## TL;DR

This paper outlines key regulatory considerations for using medicines during pregnancy, aiming to improve safety and research practices.

## Contribution

The paper provides a harmonized framework for studying medicines in pregnancy based on global regulatory guidance.

## Key findings

- Four main areas for medicine use in pregnancy were identified: product development, interventional studies, post-marketing, and full lifecycle considerations.
- Harmonized guidance is needed to study medicines in pregnancy and ensure safety surveillance.
- Regulatory insights can aid in planning research programs for medicines used during pregnancy.

## Abstract

The thalidomide tragedy of the 1960s led to restrictions and limitations in the participation of pregnant women in clinical trials. Despite the paucity of information on the safe and effective use of medicines in this population, most pregnant women are prescribed medications. A landscape assessment review of guidelines and legislation governing the use of medicines in pregnancy and during breastfeeding was conducted by the TransCelerate Pharmacovigilance Pregnancy and Breastfeeding Team. Insights from the landscape assessment review were compiled to identify important points to consider concerning the use of medicines in pregnancy throughout a product lifecycle. Four main areas were identified for consideration for use of medicines in pregnancy: (1) Product development considerations: Key points on the disease itself, the medicine characteristics, non-clinical and clinical development. (2) Interventional study considerations: Key aspects in enrollment of pregnant women in clinical trials and the follow-up requirements for such women. (3) Post-marketing considerations: Key elements in spontaneous case reporting of medicines exposure during pregnancy, implementation of appropriate risk management plans for medicines likely to be used in pregnancy. (4) Full lifecycle considerations: Activities required by regulators to ensure safety surveillance and maintenance throughout product lifecycle. There is a need for harmonized guidance on how to study the use of medicine in pregnancy. This paper addresses regulatory considerations, to aid in the planning and execution of research programs focused on developing medicines for use in pregnancy when permissible under established regulatory framework.
