Microbiology data requirements for Submissions for registration of sterile products
- 1. Microbiology data requirements for Submissions for registration of sterile products Joanne Wilson Senior Microbiologist, Microbiology Section, Office of Laboratories & Scientific Services, Monitoring & Compliance, TGA ARCS Scientific Congress 2014 10 September 2014
- 2. Microbiology data requirements • Terminally sterilised products – Moist heat (steam) sterilised – EO or radiation sterilised • Aseptically manufactured products • Finished product testing • Multidose products • Common deficiencies Microbiology Data Requirements for Submissions for 1 Registration of Sterile Products
- 3. Microbiology data requirements This is nothing new Microbiology Data Requirements for Submissions for 2 Registration of Sterile Products
- 4. Terminally sterilised products • Usually moist heat (steam) sterilised (autoclaving) • Sometimes EO or radiation (usually for implants) sterilised A minimum Sterility Assurance Level (SAL) of 10-6 must be demonstrated • This information also applies to sterile drug substances 3
- 5. Terminally sterilised products Moist heat (steam) sterilisation • Pre-sterilisation bioburden information • Physical and microbiological validation information, including: – Cycle parameters and validation parameters – Details of empty chamber studies – Heat distribution and penetration studies – Details of the Biological Indicator used – BI configuration – Confirmation of BI enumeration – Calculations of SAL – Frequency of revalidation • Information required for every site • Definition of a ‘batch’ Microbiology Data Requirements for Submissions for 4 Registration of Sterile Products
- 6. Terminally sterilised products • Guidance available: – ISO 11135-1:2007 for EO – ISO 11137 Parts 1-3 for radiation • Other methods need to demonstrate a minimum SAL of 10-6 • Bioburden information • Validation report • Information required for every site 5 Ethylene Oxide and radiation sterilisation Microbiology Data Requirements for Submissions for Registration of Sterile Products
- 7. 6 Aseptically manufactured products • Products sterilised by filtration and then aseptically filled • Some products manufactured completely aseptically Microbiology Data Requirements for Submissions for Registration of Sterile Products
- 8. Aseptically manufactured products • Bioburden information • Sterilising filter integrity testing • Sterilising filter validation – including bacterial retention studies applicable to conditions of use • Parameters and validation of depyrogenation/sterilisation processes applied to the containers and closures – A minimum SAL of 10-6 is expected for product contact parts • Media fills – Worst case conditions – Sterile hold and filling times – Acceptance criteria – Results from the past 12 months • Container closure integrity • Information required for every site • Definition of a ‘batch’ Microbiology Data Requirements for Submissions for 7 Registration of Sterile Products
- 9. 8 Finished product testing • Sterility testing – Pharmacopoeial Test for Sterility – Rapid methods (refer Ph.Eur. 5.1.6) • Parametric release – in-process testing Microbiology Data Requirements for Submissions for Registration of Sterile Products
- 10. 9 Multidose products • Preservative efficacy testing to comply with TGO 77 – Beginning of closed shelf life – End of closed shelf life • Justification of open shelf life with microbiological simulated in-use testing
- 11. Common deficiencies • Validation studies not provided in English • Extracts of studies submitted that do not provide enough relevant information to allow evaluation • Bacterial retention studies for the sterilising filter not provided • Results of media fill runs provided that are many years old • For moist heat (steam) sterilisation, physical validation information only – microbiological data must be included • Container/closure integrity validation not provided • Information not provided for all sites of finished product manufacture • For multidose products, simulated in-use studies absent or without microbiological results Microbiology Data Requirements for Submissions for 10 Registration of Sterile Products
