On March 4, 2016, China Food and Drug Administration (CFDA) issued a new regulation - ¡°the Work Plan for Reforming Chemical Drugs Registration Classification System ¡°;
The New Classification System (2016 version) changed the previous chemical drug classification system (2007 version) and sets forth new registration requirements for applicants.

5 years |
Class 2: Improved new drugs which have never been marketed within or outside China |
2.1 - Drug substances or preparations which contain optical
isomers of the known active ingredients by using the splitting or
the synthesis method; turn known active ingredients into ester or
salt (including salt containing hydrogen bonds or coordination
bonds); change the acid radical, alkali base or metal element of the
known active ingredients of salts; or turn into other non-covalent
bond derivatives (such as complex chelate or inclusion compound),
which also have an obvious clinical advantage.
2.2 - New drug preparations using the new dosage form (including the
new drug delivery system); the new prescription process or the
administration route for known active ingredients, and with an
obvious clinical advantage.
2.3 - New compound preparations of known active ingredients, which
