Lyophilization, often used to enhance detection limits by removing water and concentrating analytes, may cause analyte losses. This study evaluated the impact of lyophilization on the recovery of antioxidants and UV stabilizers across different matrices. Solutions of six potential leachables-4-hydroxybenzophenone, Uvinul 3030 (UV stabilizers), Irganox 245, Irganox MD 1024, BHT, and Irganox 1010 (antioxidants)-were prepared in acetonitrile/water, saline, and a biological-like matrix. Recovery after lyophilization and reconstitution was quantified using HPLC-DAD, with T-tests (n = 6) comparing analyte retentions. Results showed that high-vapor-pressure antioxidants (e.g., BHT) suffered significant losses, while complex matrices improved retention. Biological-like media provided the highest retention (p < 0.01), exceeding saline and acetonitrile/water. Saline solutions resulted in more significant losses than biological-like media. These findings highlight that lyophilization may be unsuitable for salt-based solutions due to volatile analyte losses. The study illustrates the importance of considering analyte properties and matrix composition when optimizing sample preparation for detecting leachables in pharmaceutical and biological systems.</p>","PeriodicalId":19986,"journal":{"name":"PDA Journal of Pharmaceutical Science and Technology","volume":"79 4","pages":"436-437"},"PeriodicalIF":0.0,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144765174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This poster presents case study data on two applications of non-destructive, deterministic Container Closure Integrity Testing (CCIT) technologies: Vacuum Decay for IV bags and MicroCurrent (HVLDmc) for pre-filled syringes. The first study evaluates the effectiveness of Vacuum Decay Technology in detecting micro defects in 200 mL and 300 mL IV bags. A statistical footprint was established using thirty negative controls, followed by testing IV bags with defects ranging from 5 μm to 20 μm. Results confirm reliable detection of 20 μm leaks in both sizes, with a demonstrated sensitivity down to 10 μm at six standard deviations (LOD6SD) in 300 mL bags. The study further validates the robustness of Vacuum Decay by showing consistent leak detection across various defect locations and sample orientations. The second study assesses the repeatability of the HVLDmc technology in detecting defects in pre-filled syringes over four weeks. Weekly testing confirmed consistent identification of negative controls, while all positive controls were detected in the first two weeks. In weeks three and four, two positive samples were not detected, possibly due to defect variability or clogging effects. These findings highlight the robustness of HVLDmc while emphasizing the need to understand defect characteristics and influencing factors. Key Takeaways: Gain a deeper Understanding the role of two technologies in parenteral packaging integrity testing. Effectiveness of Vacuum Decay for IV Bags • Vacuum Decay Technology reliably detects leaks as small as 10 μm in 300 mL IV bags with a statistical confidence level (LOD6SD). • Leak detection is consistent across various defect locations (bag body and ports) and sample orientations within the test chamber. • Demonstrates non-destructive and deterministic testing for IV bag integrity. Repeatability of HVLD MicroCurrent for Pre-Filled Syringes • HVLDmc provides a reliable method for leak detection in pre-filled syringes over a multi-week study. Practical Implications for Parenteral Drug Manufacturers • The importance of repeatability studies in CCIT to ensure robustness and reliability. • Considerations for sample preparation and defect consistency when implementing these technologies. • Reinforces compliance with regulatory expectations for deterministic, non-destructive integrity testing.</p>","PeriodicalId":19986,"journal":{"name":"PDA Journal of Pharmaceutical Science and Technology","volume":"79 4","pages":"480-481"},"PeriodicalIF":0.0,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144765169","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When executed between international sites, these transfers become even more intricate due to varying regulatory requirements, compliance landscapes, and operational constraints. The resultant stress placed on people, processes, and technology results in an increased likelihood of misalignment, knowledge gaps, and inefficiencies that can negatively impact project timelines, budget, and ultimate product quality. In this poster, we will discuss a refined International Technology Transfer Playbook that we have developed to successfully approach technology transfer planning and execution. Included are strategies for comprehensive scope planning, successful knowledge and process transfer, risk management, validation, operational infrastructure, and training/proficiency requirements, which lay the groundwork for successful project delivery. Through practical examples, we will illustrate how this framework leads to successful outcomes for both companies and patients.

Because the object is extended shelf life, long-term performance testing of any lyophilization containment system is essential. That testing must include not only measurement of container closure integrity (CCI), but measurement of system ability to maintain drug product water content. Both parameters depend upon stopper composition. This presentation discusses a strategy for two-year evaluation of four types of lyophilization stoppers (two bromobutyl elastomers, two chlorobutyl elastomers) in both 13 mm and 20 mm sizes, paired with borosilicate glass vials and aluminum seals. Lyophilization was performed in a commercial chamber using a solution blend of 20 mg/ml mannitol and 40 mg/ml sucrose - nitrogen backfill was to 11.6 psi. Evaluation comprised: - CCI (unsealed) - ability to maintain vacuum (24 hrs) - CCI (sealed) - ability to maintain vacuum - water vapor pressure in headspace - water content of cake - water content of stopper. The strategy proved effective in demonstrating that while all systems maintained acceptable CCI and water levels, composition of stopper does influence water level of drug product.</p>","PeriodicalId":19986,"journal":{"name":"PDA Journal of Pharmaceutical Science and Technology","volume":"79 4","pages":"432-433"},"PeriodicalIF":0.0,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144765192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This lack of information and regulatory requirements prompts questions on whether it is necessary to have a separate sanitization or disinfection step after cleaning of equipment product-contact surfaces for nonsterile drug manufacturing. Per USP <1115>, microbial limits and the design for cleaning and other associated processes should be based on risks assessed and the level of control necessary based on the product. It would be beneficial to implement processes that can address both product residual and microbial contamination of equipment surfaces. Multiple factors play into the design of an effective and efficient cleaning process.

Automated swab sampling of pharmaceutical manufacturing equipment offers several advantages over hand swabbing or remote swabbing, including decreased variability, the necessity for swab qualification of operators, increased accuracy versus remote swabbing, and decreased risk to personnel. To determine if automated swabbing can replace the current state of the art in manual swabbing, The Hyde Analytical Laboratory performed a comparative analysis of manual swabbing methods, hand and remote, and an automated swabbing method using a prototype device developed by Swabbot Solutions.
