The document discusses guidelines for stability testing of new dosage forms from the International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH). It defines a new dosage form as a different drug product type containing the same active substance as an existing approved product. For new dosage forms, stability protocols should generally follow the ICH parent stability guideline, but a reduced stability database may be acceptable at submission time in some cases, such as 6 months accelerated and 6 months long term data from ongoing studies. The guidelines provide recommendations for stability data submission for new dosage forms by the original application owner.
