Can these data be jointly modeled to draw any inference on the risk/benefit of a drug? Are there methods to handle this - if so what are they - if not can they be developed?

Pre - Clinical Phase Get the Statisticians more involved in the pre clinical and early clinical investigations, where value is created in terms of knowledge . Close collaboration is needed between statisticians and research workers in drug discovery.
Clinical Trials <ul><li>This is mostly the domain of the statisticians involving </li></ul><ul><li>a high degree of responsibility in observing the </li></ul><ul><li>necessary protocols, supervising the work of others in </li></ul><ul><li>recruiting patients, detecting frauds in reporting,…. </li></ul><ul><li>Ethical and scientific issues involved in outsourcing </li></ul><ul><li>clinical trials, involving human beings, from wealthy </li></ul><ul><li>to developing countries need to be addressed. (About </li></ul><ul><li>one third of chemical trials from USA are conducted in </li></ul><ul><li>developing countries) </li></ul>
Analysis of Data Analysis of data collected from clinical trials is the most difficult job of a statistician as no data set obtained from an experiment is perfect and a routine use of available software may not be appropriate. The statistician has to be in contact with the data management staff, software experts and the research staff engaged in drug discovery, devise the appropriate statistical methodology for analysis of data.
Statisticians, not statistics, are important The technical analysis of any large collection of data is a task of a highly trained and expensive man who knows the mathematical theory of statistics inside and out. Otherwise the outcome is likely to be a collection of drawings( produced by some software) interesting enough in a colored Sunday Supplement, but hardly the sort of thing from which to draw reliable inference. - Eric T. Bell Mathematics : Queen and Servant of Science, p.383
Reporting of Results This is the job of the statistician in collaboration with the research staff. The guidelines for reporting the results are available, but conveying the efficacy of the new drug and side effects in clear terms needs some experience.
Role and Responsibilities An advertisement for the post of a statistician by Pfizer Co The statistician will be an integral member of a systems biology team which develops and/or uses computational and statistical approaches to manage and derive knowledge of biological processes from large biological datasets (e.g., expression profiling, and other ‘omics’ sets) Teams will consist of computational biologists, geneticists, statisticians and bioinformatics specialists. These statistician positions are unique in requiring a substantial working knowledge biology. This is necessary in order to collaborate effectively with biologists in the design of appropriate experiments that will effectively elucidate the biological processes underpinning metabolic diseases
It pays to have statisticians on TOP and not on TAP Thank You
