Selecting appropriate excipients for paediatric dosage form - Paediatric excipients risk assessment (PERA) framework - Part 1.

Excipients are often the major component of the formulation that critically affect the dosage form, manufacturing process, product performance, stability and safety. They exert different roles and functions in a dosage form. Selecting excipients with appropriate safety and tolerability is a major hurdle in paediatric formulation development.

Paediatric excipient risk assessment (PERA) tool and application for selecting appropriate excipients for paediatric dosage forms - Part 2.

It is necessary to use a scientifically sound process for excipient risk evaluation, selection, and management in order to develop paediatric medicinal products that are both safe and effective. The "Paediatric Excipient Risk Assessment (PERA)" framework, which proposes a comprehensive approach by considering all relevant factors related to patient, dosage form, and excipient attributes, was developed and published as part 1 of this paper series, to enable the rational selection of excipients for paediatric medicinal products. This article is Part 2 of the series and presents the PERA tool that allows easy adoption of the PERA framework.

Science-Based Approach to Harmonize Contraception Recommendations in Clinical Trials and Pharmaceutical Labels.

This review presents a European Federation of Pharmaceutical Industries and Association/PreClinical Development Expert Group (EFPIA-PDEG) topic group consensus on a data-driven approach to harmonized contraception recommendations for clinical trial protocols and product labeling. There is no international agreement in pharmaceutical clinical trial protocols or product labeling on when/if female and/or male contraception is warranted and for how long after the last dose. This absence of consensus has resulted in different recommendations among regions.

Concordance of 3 alternative teratogenicity assays with results from corresponding in vivo embryo-fetal development studies: Final report from the International Consortium for Innovation and Quality in Pharmaceutical Development (IQ) DruSafe working group 2.

An IQ DruSafe working group evaluated the concordance of 3 alternative teratogenicity assays (rat whole embryo culture, rWEC; zebrafish embryo culture, ZEC; and murine embryonic stem cells, mESC) with findings from rat or rabbit embryo-fetal development (EFD) studies. Data for 90 individual compounds from 9 companies were entered into a database. In vivo findings were deemed positive if malformations or embryo-fetal lethality were reported in either species.
