25 May 2012 Basel, Switzerland. A philosophical exploration - Scientific understanding and risk-based regulatory decisions on Quality by Design. How good are the scientific explanations in regulatory submissions? Scientific explanations yield understanding; quality of explanations differ.What role can Chemometrics, Pharmacometics and Econometrics play? Understanding multidisciplinary (cGMP, CMC, Clin. Pharm., Tox., Clinical, Public Health) perspectives on risk is important. Opportunities; only when the disciplinary divides are bridged. Within the regulatory realm how we set specifications and assess risk have progressed incrementally; at this rate the Vision 2020 may be expected to be visible broadly over time, by 2020?
