China DMF Inactive Number by CDE. Complete but not approved.
China DMF Active Number by CDE. Activated/Approved.
For Drug master filing (DMF) in China, there is a new guideline released by China’s NMPA (Formerly CFDA) in 2019 for the scope of active pharmaceutical ingredients (APIs), excipients and packaging materials. Similar to the systems of US DMF, Canadian DMF and EU CEP, the new guideline helps protect manufacturers from disclosing confidential information to their distributors and specifies a more direct route to communicating with China health authorities, e.g., Center for drug evaluation (CDE).
Applicants who already have US DMF, Canadian DMF and EU CEP will benefit from overlapping data, although they’re differences in local data requirements.
The new DMF filing system in China helps protect the supplier from disclosing unnecessary confidential data to the drug applicant which enables a direct path to exchange communication with China’s health authority namely Centre for drug evaluation (CDE).
What are inactive and active DMF numbers in China?
The applicant prepares China DMF dossier and file application to CDE for completeness review for allocation of DMF filing number with a status of “I” for “Inactive”.
Upon drug product registration, for example ANDA or new drug application; CDE will refer to the inactive DMF filing number and review the DMF dossier together with the drug dossier and then activate the DMF filing number shown as “A” for active. The “I” and “A” status will officially display on CDE database.
