Turkey-TITCK (Türkiye İlaçveTıbbiCihazKurumu)-Approval Processes for Biological Products

1. Correct Product Name and License Information:
   • Ensure that the product name in the cover letter, application form, and related documents matches the information stated in the license.
2. Consistent Variation Application Type:
   • The variation application type must be consistent and mentioned both in the cover letter and the application form.
3. Verification of Attachments:
   • Confirm that all attachments mentioned in the cover letter are uploaded to the Electronic Document Management System (EBYS).
4. Response to Deficiency Letter:
   • Respond to deficiency letters issued by the institution via EBYS using the same tracking number.
5. Same Date for Different Products:
   • Applications for different products with the same variation subject must be submitted on the same date.
6. Focused Variation Information:
   • Submit only information and documents directly related to the variation as attachments in variation applications.
7. Separate Fee for Group Variation:
   • For group variation, pay a separate accrual fee for each application, and clearly state each application separately in the cover letter.
8. Adherence to Variation Guide:
   • Ensure compliance with the conditions outlined in the Guide on Variations in Licensed Medicinal Products for Human Use, especially regarding the “test method.”
9. Product-Specific Information:
   • Include only information and findings related to the product in question, avoiding data from different products in the application file.
10. Batch Size Information:
    • Submit batch size information for all batches produced since pharmaceutical development.
11. Stability Studies for Special Conditions:
    • Provide stability studies for products with special storage conditions, including shelf life after reconstitution/dilution, alternative shelf life, and shelf life after opening.
12. Submission of Stress Stability Studies:
    • Submit stress stability studies for products, such as photostability studies for light-sensitive products. Include results with acceptance criterion ranges for the relevant analysis.
13. Quantitative Data Presentation:
    • Present results of studies in the file with specific quantitative data rather than using the generic term “appropriate.”
14. Legible Presentation of Data:
    • Ensure that presented chromatograms, gel images, etc., are clear, legible, and selectable.
15. Caution Regarding Biosimilar Comparison Studies:
    • Avoid using a reference standard instead of a reference medicinal product in biosimilar comparison studies.
16. Extractable and Leachable Studies:
    • Conduct necessary studies on extractable and leachable substances and present the results.
17. In Vitro Activity and Binding Studies:
    • In preclinical investigations, compare products in a sufficient number of series to demonstrate similarity in in vitro activity and binding studies.
18. Detailed Patient Information in Clinical Studies:
    • Provide detailed information about the number of patients and patient exclusion criteria in clinical studies.
19. Detailed Information on Batches Used in Clinical Studies:
    • Offer comprehensive information about the batches used in clinical studies, including serial numbers, production location, and the source of the active substance.
20. Correct Animal Model in In Vivo Studies:
    • Ensure the correct choice of the animal model in in vivo studies.
21. Summary Tables for Studies:
    • Include summary tables containing all preclinical and clinical studies at the beginning of the relevant module.
22. Avoiding Use of Clinical Data to Justify Quality Differences:

Do not use clinical data to justify significant differences in quality characteristics. Provide independent justifications for quality differences.
