Development and Qualification of Visible Particle Load Analysis Methods for Injectable Drug Product Primary Packaging...

Area of Science:

• Pharmaceutical Sciences
• Analytical Chemistry
• Quality Control

Background:

• Particulate contamination in drug products can lead to costly recalls.
• Existing pharmacopeial methods (USP <787>, <788>) cover filled drug products but not primary packaging.
• Lack of standardized methods for assessing particle load in unfilled primary packaging components (tubs, nests, bags) poses a quality risk.

Purpose of the Study:

• To describe a novel quantification method for assessing particle levels in primary packaging components and closures.
• To establish a standardized approach for measuring visible particle load in both siliconized and nonsiliconized primary packaging systems.
• To aid biopharmaceutical manufacturers in refining processes to minimize particulate contamination.

Main Methods:

• Development of physical rinse methods to extract particles from primary packaging components.
• Utilizing microscopy for particle counting, allowing user-defined size ranges.
• Qualification of the developed method to ensure accurate measurement of visible particle load.

Main Results:

• A robust method was developed to accurately quantify particles in primary packaging.
• The method is applicable to both siliconized and nonsiliconized primary packaging systems.
• Critical parameters for developing effective physical rinse methods were identified.

Conclusions:

• The described method fills a critical gap in pharmacopeial standards for particle analysis of unfilled primary packaging.
• Accurate particle load assessment is crucial for ensuring drug product safety and quality.
• Standardized methods enable better process control and reduction of particulate contamination.
