The Pharmacoepidemiological Research on Outcomes of Therapeutics by a European Consortium is a collaborative European project that comprises a programme to address limitations of current methods in the field of pharmacoepidemiology and pharmacovigilance. The European Medicines Agency (EMA) is the coordinator of PROTECT and GSK is the deputy co-ordinator of PROTECT. They manage a multi-national consortium of 34 partners including academics, regulators, SMEs and EFPIA companies
PROTECT WP 3.7 has published two studies on the masking effect of measures of disproportionality analyses. The authors of these studies have developed and validated a mathematical algorithm aimed at identifying the presence, direction and magnitude of a masking effect associated with the use of quantitative methods based on disproportionality analysis (ROR, PRR and RRR). This algorithm has been used on two spontaneous reporting databases (EudraVigilance and Pfizer databases). The study suggests that important masking associated with a single (highest) masking product might be rare, is induced by products for which the reaction is known or has been extensively or over reported. The masking mainly affects events rarely reported in the database. These two studies have been published in Pharmacoepidemiology and Drug Safety. They can be found here.
PROTECT publishes the final recommendations Report from WP5 on the IMI-PROTECT Benefit Risk.
PROTECT publishes presentations and posters from the 29th ICPE Meeting.
Presentations and posters from the 29th ICPE Meeting held in Montreal on the 25-28 August 2013 are now on line on THE PROTECT website.
Please find them here.
PROTECT publishes reviews of benefit - risk methods and results of real-life case studies
PROTECT has published reviews of available methodologies for the assessment, integration and visualisation of the benefit-risk of medicines, as well as recommendations on methods of graphical expression for use by patients, healthcare providers, the pharmaceutical industry and regulators. Results of real-life case studies comparing methods with different levels of complexity are also posted. These case studies were conducted in two waves and concern the following medicines: efalizumab, natalizumab, rimonabant, rosiglitazone, telithromycin and warfarin.
The reports are available here.
