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
![Page 6: Pharmacovigilance the OTHER discovery process in Pharma Daniel Mayer, Product Marketing Manager Olivier Feller, Life Sciences Consultant 7th Text Mining](https://reader036.vdocuments.us/reader036/viewer/2022081602/5519ee4b550346d67b8b4c53/html5/thumbnails/6.jpg)

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
![Page 7: Pharmacovigilance the OTHER discovery process in Pharma Daniel Mayer, Product Marketing Manager Olivier Feller, Life Sciences Consultant 7th Text Mining](https://reader036.vdocuments.us/reader036/viewer/2022081602/5519ee4b550346d67b8b4c53/html5/thumbnails/7.jpg)

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
![Page 8: Pharmacovigilance the OTHER discovery process in Pharma Daniel Mayer, Product Marketing Manager Olivier Feller, Life Sciences Consultant 7th Text Mining](https://reader036.vdocuments.us/reader036/viewer/2022081602/5519ee4b550346d67b8b4c53/html5/thumbnails/8.jpg)

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
![Page 9: Pharmacovigilance the OTHER discovery process in Pharma Daniel Mayer, Product Marketing Manager Olivier Feller, Life Sciences Consultant 7th Text Mining](https://reader036.vdocuments.us/reader036/viewer/2022081602/5519ee4b550346d67b8b4c53/html5/thumbnails/9.jpg)

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
![Page 10: Pharmacovigilance the OTHER discovery process in Pharma Daniel Mayer, Product Marketing Manager Olivier Feller, Life Sciences Consultant 7th Text Mining](https://reader036.vdocuments.us/reader036/viewer/2022081602/5519ee4b550346d67b8b4c53/html5/thumbnails/10.jpg)

What typical Pharmacovigilance questions does Text Mining need to address ?
Which unexpected ADRs have been reported for this drug ?
Which populations have been exposed to unexpected ADRs ? • Age• Ethnic characteristics
Which treatment caused ADRs ?• Dosages, Duration, Frequency, Administration Route• For which Indication
What was tested during the Clinical Trials ?

Value Proposition in Pharmacovigilance
Boost the productivity of Contraindication Discovery• Scientists process a higher number of more relevant sources in less time
and develop faster and deeper insight into the specific context.• Discover and Investigate unexpected ADRs faster• Discard ADRs that are expected• Develop Contraindication insights faster
