Situation 1987

• Relatively simple statistics in design and analysis used in clinical trials 1987.

• Regulatory authorities started to become more demanding (FDA mostly).

• Almost no statistics provided by professional statisticians existed in preclinical research.

• Computer facilities rather primitive, start of advanced database technology (Oracle), SAS, BMDP, lack of harmonization on data standards.

Globalization

• Global companies and global markets, multinational studies, bridging• Cooperation between authorities (FDA, EMA, Japan…)• Strong professional organizations (ISCB, DIA, EFSPI, ASA, PSI..)• International conferences• Biopharmaceutical statistical science becomes global with dedicated journals

- J. of Biopharmaceutical Statistics (US, 21st year)

- Pharmaceutical Statistics (PSI, 10th year) - Statistics in Biopharmaceutical Research (ASA, 3rd year)

Public trust challenged

• The JAMA story

• Ethics code

• Authorization of statisticians

Quotation from a related area

• “The work during the past 30 years in has in the best case been

sensationally worthless or in the worst case directly detrimental”

• “… the more frequent use of these models implied that the became less interested in the reality and more fascinated of mathematical relations”
