PUPSIT Simulation as part of Process-Specific Bacterial Retention Testing (PUPSIT-BCT): Poster Presented at PDA Week...

Area of Science:

• Pharmaceutical Manufacturing
• Sterile Filtration Technology
• Regulatory Compliance

Background:

• Sterile filtration is critical in pharmaceutical manufacturing, governed by regulations like Eudralex Volume 4, Annex 1.
• Pre-Use Post Sterilization Integrity Testing (PUPSIT) is a standard procedure for drug manufacturers.
• Process-specific bacterial retention testing is essential for sterile filter validation.

Purpose of the Study:

• To investigate whether PUPSIT conditions should be simulated during process-specific bacterial retention testing.
• To determine how to effectively simulate PUPSIT conditions within bacterial retention tests.
• To present a risk-based bacterial retention test design incorporating PUPSIT simulation.

Main Methods:

• Evaluation of process-specific conditions and potential impacts of PUPSIT on filter integrity.
• Development of a risk-based bacterial retention test design.
• Incorporation of a PUPSIT simulation phase into the testing protocol.

Main Results:

• PUPSIT introduces mechanical stress and potential bioburden introduction routes.
• A risk-based approach can effectively incorporate PUPSIT simulation into bacterial retention testing.
• The proposed design aims to rule out impacts on sterile filtration efficacy.

Conclusions:

• Simulating PUPSIT during bacterial retention testing is necessary for comprehensive sterile filter validation.
• A risk-based testing strategy, including PUPSIT simulation, ensures the integrity and efficacy of sterile filters.
• This approach enhances the reliability of sterile filtration processes in pharmaceutical manufacturing.
