The development cost and timeline for a new drug is increasing due to high attrition rates caused by inadequate physicochemical and biopharmaceutical attributes, unacceptable safety, and sub-marginal efficacy. This development attrition rate can be reduced by strengthening non-clinical formulation screening process and establishing a drug product developability assessment plan to enable nimble selection of developable compounds to move to the clinic. It is critical to select the right formulation principles, and equally important to run developability screens by:
