17 Bernhard Huitfeldt 24 Oct 201217 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.

23 Bernhard Huitfeldt 24 Oct 201223 Computer technology and software 1987 - 2012 –Increase of speed and capacity of computers Database technology, increased volumes of data, bioinformatics, computer intensive methods –General statistics software packages, new procedures in SAS, SPSS, S-plus, R etc. –Special statistics software East, nQuery + interim, ADAPT, BUGS etc.

24 Bernhard Huitfeldt 24 Oct 201224 Regulatory guidelines 1987 - 2012 –International Conference of Harmonization (ICH) Safety, Quality, Efficacy (E9 and E10 etc.) –Food Drug Administration (FDA) General methodology and disease specific guidelines –European Medicines Agency Points to consider

25 Bernhard Huitfeldt 24 Oct 201225 ICH/E9

26 Bernhard Huitfeldt 24 Oct 201226 Dagens Industri 14 september 2004 “När sedan FDA:s statistikexpert gick till angrepp blev det den sista spiken i kistan ……..”

27 Bernhard Huitfeldt 24 Oct 201227 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)

28 Bernhard Huitfeldt 24 Oct 201228 Public trust challenged The JAMA story Ethics code Authorization of statisticians

29 Bernhard Huitfeldt 24 Oct 201229 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” macroeconomy economists

30 Bernhard Huitfeldt 24 Oct 201230 The evolution of biostatistics?

31 Bernhard Huitfeldt 24 Oct 201231 Happy birthday! We can be proud of what we have achieved so far We have many challenges to tackle in the future
