Abstract:
Ensuring the sterility of pharmaceutical products, particularly those administered parenterally, is crucial for patient safety. Conventional sterility testing methods, while reliable, require incubation periods of up to 14 days, delaying product release. Therefore, exploring alternative rapid microbiological methods is essential for improving testing efficiency and reducing the time-to-result (TTR). This study evaluates the Red One™ system, a novel rapid method utilizing solid-phase cytometry and esterase-based activity staining, which reduces the TTR to just 96 h. Our results demonstrate the non-inferiority of the Red One™ system compared to traditional culture-based techniques by assessing key performance parameters, including limit of detection, accuracy, robustness, and ruggedness for various microorganisms, including slow-growing species such as Cutibacterium acnes. Our results indicate that this alternative system is an effective method for rapid sterility testing in the pharmaceutical industry.
Insights
This study validates the Red One™ system, a rapid microbiological method for pharmaceutical sterility testing. It significantly reduces the time-to-result from 14 days to 96 hours, ensuring patient safety without compromising accuracy.
Area of Science:
- Pharmaceutical Microbiology
- Analytical Chemistry
- Biotechnology
Background:
- Sterility testing is critical for pharmaceutical product safety, especially for parenteral drugs.
- Conventional sterility testing methods have long incubation times (up to 14 days), delaying product release.
- Rapid microbiological methods are needed to improve efficiency and reduce time-to-result (TTR).
Purpose of the Study:
- To evaluate the performance of the Red One™ system as a rapid sterility testing method.
- To compare the Red One™ system against traditional culture-based sterility testing.
