After summarize the evaluation results of dossiers in recent times revealed that the preparation of drug registration dossier of almost companies has not been paid adequately attention, the quality of dossiers is still low and it is required to be supplemented many times (more than 95% of registration dossier for domestic drugs and 75% of registration dossiers for foreign drugs have not met the requirements after the first evaluation); the consequence is that the experts had to review the reg. dossier in many times that causing a long delay for the evaluation and granting of registration numbers from the authority, affecting the production and business of the companies.

In order to enhance the companies’ responsibility, the quality of dossiers, shorten the time line frame for the evaluation of drug registration dossiers, ensure the publicity, transparency and uniformity in the process of evaluation drug registration dossiers, Drug Administration have issued: “Guiding on evaluation for drug registration dossiers” (be sent together with this official letter). This is the basis for experts proposing to Drug Administration in the process of evaluation drug registrations dossiers.

Sincere thanks for the co-operation of the experts.
