Need of STEP database

Nearly all medicines are formulated with excipients that have been used for many years and are generally regarded as safe (GRAS). They are defined in monographs in the various pharmacopoeias and released on certificates of analysis against monograph specifications, using monograph test methods. However, these monographs are usually intended to cover use in adults and some excipients are less well tolerated in children, especially young children whose physiological systems are still undergoing development.

Excipients may be toxic, carcinogenic, mutagenic, teratogenic, or affect reproduction. Assessing the safety of excipients is an essential element of the research and development process. Detailed assessments of these compounds must be included in applications submitted to regulatory authorities. Extensive excipient safety data is publicly available in peer-reviewed scientific journals and government reports and databases, but there is very limited paediatric data which can be used for development of paediatric medicines and is distributed over many sources. This safety data has never been incorporated into a single comprehensive and readily accessible database. At the present time, industry and regulators have no central source of safety data on which to base decisions regarding the need for additional safety studies. Therefore, there is a risk that some such studies may be conducted unnecessarily or on the other hand highlight some studies that are required/necessary to be carried out.

There is no repository of excipients information (e.g., dose information, PK) that could   (i) provide a basis for screening and selecting excipients for use in paediatric product development; and (ii) expedite further product-specific safety and toxicity studies.

Your feedback is welcome

The data collection and extraction for STEP is in process. However, EuPFI invites volunteers who wish to work on the data collection, extraction and population for STEP and researches who work on the safety and toxicity of excipients to provide information on their findings for inclusion in STEP.
