Generally accepted scientific knowledge: FDA explains how it applies to nonclinical data in drug apps
Following an “increasing number of questions” on the extent to which generally accepted scientific knowledge (GASK) may be relied on by the FDA as part of approval decisions, the agency today put out a new, 6-page draft guidance on the topic of GASK, with examples of when it might be used appropriately.
