2 Copyright © 2009 TEMIS - All Rights Reserved - Slide 2 Agenda A process view of safety in pharma Why is pharmacovigilance necessary ? Clinical Trials have key benefits but also some limits But how important and urgent is this issue ? Where does pharmacovigilance fit in the process ? A new definition of Pharmacovigilance What role does Text Mining play in Pharmacovigilance ? How is Luxid® used for this purpose ?

5 Copyright © 2009 TEMIS - All Rights Reserved - Slide 5 Benefits and Limitations of Clinical Trials Clinical Trials proove with some certainty that the product is effective and identify the common serious adverse events but have limitations

6 Copyright © 2009 TEMIS - All Rights Reserved - Slide 6 Benefits and Limitations of Clinical Trials Clinical Trials proove with some certainty that the product is effective and identify the common serious adverse events but have limitations Relatively Homogeneous populations Relatively healthy patients with only one disease Patients with complicated medical conditions often excluded Not sufficiently ethnically diverse Specific groups such as pregnant women, children, and elderly people are mostly excluded

7 Copyright © 2009 TEMIS - All Rights Reserved - Slide 7 Benefits and Limitations of Clinical Trials Clinical Trials proove with some certainty that the product is effective and identify the common serious adverse events but have limitations Relatively Homogeneous populations Small sample size rarely more than 3000 patients reduces the chance of finding rare adverse effects

8 Copyright © 2009 TEMIS - All Rights Reserved - Slide 8 Benefits and Limitations of Clinical Trials Clinical Trials proove with some certainty that the product is effective and identify the common serious adverse events but have limitations Relatively Homogeneous populations Small sample size Limited duration long term consequences such as cancer cannot be discovered

9 Copyright © 2009 TEMIS - All Rights Reserved - Slide 9 Benefits and Limitations of Clinical Trials Clinical Trials proove with some certainty that the product is effective and identify the common serious adverse events but have limitations Relatively Homogeneous populations Small sample size Limited duration Difficulty to predict the real world Patients receiving certain concurrent drugs are often excluded Drug interactions can therefore almost never be predicted from clinical trials, even though they may be substantial Food-drug interactions are also not covered

10 Copyright © 2009 TEMIS - All Rights Reserved - Slide 10 Benefits and Limitations of Clinical Trials Clinical Trials proove with some certainty that the product is effective and identify the common serious adverse events but have limitations Relatively Homogeneous populations Small sample size Limited duration Difficulty to predict the real world … but how urgent and important is it to address this issue ?
