The purpose of this RFI is to seek input from potential users regarding the data elements and information to be collected in a minimal and expanded Data Base of excipients that are used in pediatric formulations.
This is a time-sensitive Request for Information that will be used to obtain knowledge and information for project planning purposes only.This is a Request for Information (RFI), NOT a solicitation for proposals, applications, proposal abstracts, or quotations. This RFI should not be construed as an obligation in any way on the part of the United States (U.S.) Federal government. The Federal Government will not pay for the preparation of any information submitted and/or for the government's use of that information. Additionally, the government cannot guarantee the confidentiality of the information provided.(See Confidentiality Section below).
The Obstetric and Pediatric Pharmacology Branch (OPPB) within The Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) is involved with the planning and implementation of the Best Pharmaceuticals for Children Act (BPCA) 2007 (http://bpca.nichd.nih.gov/ ). The BPCA 2007 authorizes the NICHD, in consultation with the U.S. FDA and experts in pediatric research, to identify therapeutic gaps in pediatric diseases, disorders or conditions in which more complete knowledge of treatment strategies, including drugs and biologics, may be beneficial to the pediatric population. The lack of adequate pediatric formulations has been identified as a major obstacle for the study and use of drugs in children.
While concern has been focused on the medicinal component of the drug formulations administered, the history of drug toxicity in children has several examples of pediatric tragedies that have their origins in the excipients employed rather than the drugs used in the formulation preparation.
In 2006 NICHD created the United States Pediatric Formulations Initiative (US PFI) to address safety issues and problems associated with the lack of adequate pediatric formulations (Clin. Ther .2008;30 (11) 2097-2101). A similar Pediatric Formulation Initiative was created in 2008 in the European Union. (EU PFI).
The US and EU-PFIs are working together to examine the risks of excipients in pediatrics, to identify gaps in safety information, and ultimately create and maintain a pediatric excipients database that is available to drug sponsors, scientists and the public.
For this purpose a joint EU-US PFIs Excipients Working Group has been formed to develop a strategy for conducting a high-level scientific literature review to evaluate acceptable excipients for children. The working group will determine a prioritization process for selected excipients based on: the strength of the literature evidence; broad applicability across the pharmaceutical industry; and potential for endorsement in Europe, US and worldwide following regulatory screening.
A number of issues have thus far emerged related to determination of how estimates have been made of acceptable recipient’s exposure, the availability of developmental toxicology information, and identification of gaps in information and knowledge.
The Specialized Information Services of the National Library of Medicine (NLM) has joined the pediatric excipients initiative as a co-sponsor, to provide advice about how best to structure the search of those items that are difficult to search, search for untapped sources of information, suggestion of toxicology experts, participate in the searching process and to discuss the availability of resources and support at NLM.
Development of an Excipients Database in Pediatrics: Minimal Data Base Elements
The joint EU-US PFIs Excipients Working Group has concluded that a simple search will not produce the needed information and that a clearly defined focus will yield meaningful information. At this time the clinical consequences of excipient exposure in children are largely unknown. In addition, an accepted daily and cumulative intake of excipients have not been established in pediatrics.
A detailed review will be needed to define and establish the scope of knowledge gaps, update data on purported toxicities, and identify excipients that may impose a toxicity risk if included in pediatric formulations.
The data base structure will follow a modular model. Our initial approach would be to have a minimal database with the potential to expand with more information in later phases. The data elements listed below would be included as a part of this initial minimal database.
Physicochemical excipient characterization
Demographic (age, gender etc)
Administration/Exposure (E.g., Route, dose, concentration, duration etc)
Safety/Tolerability/Adverse effects findings by organ/system (e.g. GI, CVS, respiratory, etc.)
Acceptable daily intake
NON HUMAN FIELDS
Age. Juvenile/Adult) Species (e.g. rat, mouse, dog, non human primates.)
Administration/Exposure (e.g. Route, dose, concentration, duration etc)
Toxicity findings by organ/system (eg. Genotoxicity, hepatotoxicity etc,)
Dose information (Eg., MTD, LD, NOEL, NOAEL)
In Vitro Data
Overall Purpose of the Excipients Database In Pediatrics
The NIH is especially interested in concrete and relevant suggestions in order to determine the pediatric excipient database structure that best satisfies the needs of potential users, and therefore requests the following information:
