Why is E2B Validation important?

In Pharmacovigilance -Case processing after completing the data entry process and before routing the case to the next workflow (Medical Review), it is mandatory for everyone to do a Validation check called as E2B validation, E2B validation error could also be an error associated with a special character in case study narrative or in adverse event, further if an error is reported on Validation check which cannot be rectified, a comment stating ‘E2B validation was noted and bypassed’ should be used contact log

Every wondered why?

Every ICSR (Individual case safety report) as per 21 CFR 314.80 in US and Schedule Y appendix XI in India, should be transmitted from the reporting sources to the regulatory authority and this process is also known as E2B submission (as we submitting E2B files) and because one of the mode of transmission is via XML format, if a special character found in the ICSR which is not rectified after the ICSR is converted into an XML file and upload as an E2B file in the regulatory database while doing the regulatory submission it will not accept the E2B file and prompt back with an error hence it is mandatory to always do an E2B validation.

MHRA’s Black Triangle Report

In United Kingdom, there are certain drugs in which although they were granted marketing approval by the Medicines and healthcare product regulatory agency (MHRA), they need to be closely monitored, since limited information were available about these drugs.  One of the key reasons attributed to this may be, less subjects being enrolled in the clinical trials, short therapy duration etc.…thus, in order to identify rare adverse reactions, effect of the drug in different populations or effect of the drug under different co-morbidities, such drugs are tagged with an inverted black triangle ( ▼ ) on their package insert, to ensure that these drugs are intensively monitored. The Commission on Human Medicines (CHM) and MHRA encourages expedited reporting within 15 calendar days of all such drugs with an inverted black triangle symbol if, found to have caused serious or non-serious adverse drug reaction. You may find the black triangle drugs at the Electronic

What is a ‘backward forward convertor’ ?

Did you know that ICH has a backward forward conversion (BFC) tool which was build using eXtensible Stylesheet Language Transformation (XSLTs) ? This language basically transforms a XML file of a given format into another XML file of a different format. The BFC tool requires a program that understands XSLT language to make conversion of E2B (R2) to E2B (R3) and vice versa. Now considering this, the European medical agency has improvised the BFC tool with additional fields as per the EU implementation guide. The EU version of the amended BFC tool has been published on the EMA website. The key files in the BFC package includes downgrade-icsr.xsl; which downgrades E2B (R3) file into E2B (R2) and upgrade-icsr.xsl; which upgrades E2B (R2) file into an E2B (R3) file. The acknowledgement convertors include downgrade-ack.xsl and upgrade-ack.xsl What are the technical limitations of BFC tools? However, the conversion using BFC has some major limitations. When converting I

What is an IDMP and its application in Pharmacovigilance?

In response to the demand for internationally harmonized detail of medicinal products, the IDMP which comprises of a set of five ISO norms provides the basis of identifying medicinal products. IDMP standard readily facilitates ICSR (Individual Case Safety Report) submission to regulatory agencies. The message specification in IDMP protects the integrity of medicinal product information when submitting cases to the regulatory agency. HL-7 transmissions are within the IDMP standards Health Level 7- is an international standard for facilitating data exchange between the safety/ clinical database and the regulatory agency. The five ISO norms comprise of ISO 11238 pertains to general characteristics of regulated medicinal products specifying where the product is an active pharmaceutical ingredient or an adjuvant. ISO 11238 also describes the grade of product used (purity, manufacturing information etc.…) ISO 11239 pertains to regulated information on packaging, dosage form, route
