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 Medicines Compendium, British National Formulary, Nurse Prescribers’ Formulary etc.… A black triangle symbol may be assigned to any new active drug / vaccine or even a Biosimilar (Biosimilar are similar biological therapeutic products). Black triangle is not restricted to only drugs, it may also include new route of administration, new drug delivery systems or even new patient population.

Black triangle drugs are reviewed every 2 years by the MHRA and monitoring black triangles reports helps in identifying benefit risk profile of drug and unrecognized adverse effects.

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 ...

Artificial Intelligence Seeing through the lens of Pharmacovigilance

Pharmacovigilance as we know is a science with a set of pre defined functions to collect, analyse, monitor adverse event reports in understanding the safety profile of drug. The set pre defined functions would include case processing through data entry of adverse event forms into safety database, medical review, aggregate reporting, signal detection, risk evaluation and mitigation strategies. With patients awareness and regulatory compliance we may have seen a surge of adverse event data over last few years , resulting in the urgent need for the application of automation. Pharmacovigilance is the only discipline where in which timelines and quality data are evaluated on a benchmark of 100 % and a compromise in these two parameters are considered to be a zero tolerance. Automation of above pre defined function is possible through machine learning, which is an integral components of Artificial Intelligence. What is Artificial Intelligence ?     ...
