Even as it matures, the biopharmaceutical industry is still a highly entrepreneurial one. \1\ Avis, Kenneth E.; "Parenteral Preparations", Chapter 36, pp. The US Food and Drug Administration (US FDA) effectively expects confirmation that dye ingress methods can detect leaks 20 m (6). Sci. The guidelines described in USP<1207> can be applied to any common CCI testing (CCIT) method to achieve a method suited for its intended use within a drug product lifecycle. The methylene blue test was used in 108 cases (group 1) via a nasojejunal tube. 5.6 Apply vacuum to the mark of 15 inches Hg. Differences often are found in process parameters between company-specific methods and the dye ingress test described in the US Pharmcopeia and in the European Pharmacopoeia, which means that no standard method exists. Eur. 9 Ph. 8600 Rockville Pike sharing sensitive information, make sure youre on a federal So all inner surfaces need to be wetted, and lyophilized products need to reconstituted before detection. All tests are digitally documented and the results can be exported. View complete answer on pharmaguideline.com & hold it for 2 minutes. To test the sample we place tablets sachet into the desiccator filled with Methylene blue then vacuum the desiccators for a limited time. USP 39NF34, Supplement 1. Here we provide guidelines and best practices for the qualification and/or validation and use of a dye ingress test method within a companys holistic approach to CCI. Sensitivity in terms of leak size (quantitation limit) should be appropriate for the intended use of the CCIT method, with a minimum leak size of 20 m (12) being consistently detected. Surg Endosc. The CDV Pharma is an advanced instrument incorporating a vacuum chamber and an operating system especially focused on the needs of the pharmaceutical industry. The CCI procedure is validated as a limit method (passfail) for the determination of primary package integrity. A move toward ever-decreasing defect sizes is more relevant to gas exchange than it is to liquid ingress and should be considered in determinations of appropriate sensitivity for a method. The LEAK-MASTER EASY from WITT makes the proven methylene blue test particularly fast, reliable and user-friendly: A vacuum is pulled above the water in the test chamber. 498-524 in Remingtons Pharmaceutical Sciences; Edit. Dye ingress (liquid tracer test) is still the most widely used CCIT method across the biopharmaceutical industry (3). 2 Brown H, et al. 1.5% (1.5 g/ 100 mL) density. Products: Some products do not require technologically sophisticated approaches to demonstrate integrity of their CCSs. The European Pharmacopoeia. Although the method is not always product or container compatible, where appropriate dye ingress continues to provide container assurance. International Organization for Standardization: Geneva, Switzerland, 2018. Such methods still are needed for devices and a number of other products with which other physical CCI methods are not a practical option. Detection of a positive result from an ingress method can be determined by using either instrument-based methods (e.g., UV-absorbance measurement for dyes) or by visual examination of the degree of coloration. Those data deliberately have not been outlined here because the specific parametersused vary too widely and highly depend on the product tested and its presentation. BioProcess Int. Critical review of the literature]. Advantages of Test Method When to Use: Dye ingress is a straightforward test. (concentration of dye, pressure challenge and time of exposure of sample and control units to the challenge and dye) used for In 2017, we published our response to the publication of the revised USP<1207> in BioProcess International (4). Development of a Dye Ingress Method to Assess Container-Closure Integrity: Correlation to Microbial Ingress. Careers. 6 Hughes PF. Looking toward the future, industry CCIT subject matter experts (SMEs) from most companies still would choose to apply dye ingress methods at specific stages of the lifecycles of their different products in the near future, despite the availability of deterministic methods. Methylene Blue Dye Test Method (LT-101P) + View all. Growing from an end-user group in 2008, BioPhorum now comprises 71 workstreams manufacturers and suppliers deploying their top 2,000 leaders and subject matter experts to work in six focused Phorums, articulating the industrys technology roadmap, defining the supply partner practices of the future, and developing and adopting best practices in drug substance, fillfinish, process development, and manufacturing IT. To test the integrity and tightness of blister packs in particular, the packs are placed in a container with an ethanol-based test liquid containing methylene blue as a dye. 63(5) 2009: 489498. Some possible impact factors associated with this method are lighting (type of light, intensity, position), background color and position, sample distance to inspector, use of negative and positive dye control samples, time allowed for inspection (pacing), and breaks to lessen operator fatigue. Leak-testing glass ampuls of injectables by means of vacuum- pressure treatment and methylene blue dye solution is recommended by Avis. ISO 8362-5 Annex C quotes a similar test pressure of 25 kPa. It is important to note that use of many deterministic methods is limited because they require disassembly of devices before a CCIT. Regardless of the CCI methodchosen, it must be able to detect leak sizes that correspond to the leak rate appropriate for a specific product. Requiring that all packages be absolutely free from gasleakage is not necessary or practical. Electrolab's leak tester with embedded printer is ideal for checking the leakage of packed strips, blisters, small sachets of tablets, capsules etc. Comparison with controls is performed either visually using the same type of containers or by spectroscopic measurement at absorbance maximum of the dye. The method generally is not as sensitive as helium-leak testing, laser head-space analysis, or certain other CCI methods. The .gov means its official. The 20-m Standard: The current expectation from the US regulatory agencies is that methods should be capable of detecting defect sizes equal to or below a 20-m diameter. The dye ingress method requires no sophisticated equipment, only a chamber and a time-dependent pressure control (vacuumpressure cycles), and it allows for simultaneous testing of numerous and different types of samples. Am. 0.1 to 0.2 mL/kg IV very slowly over a period of several minutes; may repeat in one hour if necessary. Technol. With the ELT-201P Electrolab launches the first and only smart verification of leak detection using the widely accepted and cost efficient blue dye method. 8 USP <381> Elastomeric Closures for Injections. 12 Burrell LS, et al. The robust acrylic housing is hygienic and easy to clean. Thanks! Limit of Detection (LoD): The detection limit of an individual analytical procedure is the lowest amount of analyte in a sample that can be detected but not necessarilyquantitated as an exact value (5). Visual inspection is the most practical and commonly used detection method for ingress testing. Tracer Liquid (Dye) Choice and Surfactant Use: For dye ingress testing, USP and the International Standards Organization (ISO) suggest a dye (e.g., methylene blue) at a concentration of 0.1% w/v (1 g/L). Intraoperative leakage rate, postoperative clinical leakage rate, length of hospitalization, and mortality rate were the outcome measures. Intraoperative Endoscopy Decreases Postoperative Complications in Laparoscopic Roux-en-Y Gastric Bypass. It must suit the needs of the stage in the products lifecycle. The test is done by placing the pack of blister into a container of vacuum leak detector which has been filled with methylene blue dye mixed with water. Results: The intraoperative leakage rate was 7.4% in group 1. Early detection and treatment of a leaking gastrojejunostomy following gastric bypass. Overview of the Method: A CCS is immersed in a colored dye solution contained in a pressure vessel. test in terms of leak detection was 20 m breach size. 4 Vanness B, et al. The blue color of the solution faded within a few hours leaving a clear transparent solution. Product-Related Considerations: Formulation characteristics such as viscosity, surface tension, color, absorption properties (e.g., fluorescence or UV absorbance) and clogging capabilities (e.g., at high-concentration of protein or suspensions) can influence ingress test results. This is because the Methylene blue (MB) is photo-degradated by the . US Pharmacopeial Convention: Rockville, MD. Identification, Infrared Absorption 197K. Methylene blue is typically given by injection into a vein. This defect criterion is applied to routine test methods and is an expected positive control. Historic data usually are available at most pharmaceutical companies, providing confidence in the dye ingress method and data. For an ingress test method, the LoD identifies the smallest concentration of dye that the method can observe. Table 2 lists other methods used to create positive controls. As particularly sensitive products, medicines require high quality packaging. Drug products combine active pharmaceutical ingredients with excipients in a final formulation for delivery to patients in liquid or lyophilized (freeze-dried) packaged forms with the latter requiring reconstitution in the clinical setting. Other parameters play a vital role in method performance: Pressures and Times: USP <381> and Ph. The test is done by placing the pack of blister into a container of vacuum leak detector which has been filled with methylene blue dye mixed with water. Suitable controls and operator training need to be in place to reduce the risk of variability on the methods end-point (discoloration of CCS due to dye penetration). The survey comprises data from 11 of the industrys leading biopharmaceutical manufacturers and considers the five most common biopharmaceutical product presentations. 3 Wolf H, et. 2012 Dec;22(12):1928-33. doi: 10.1007/s11695-012-0757-2. 11 ASTM D6653: Standard Test Methods for Determining the Effects of High Altitude on Packaging Systems by Vacuum Method. Pharm. Bioprocessing begins upstream, most often with culturing of animal or microbial cells in a range of vessel types (such as bags or stirred tanks) using different controlled feeding, aerating, and process strategies. View complete answer on pharmaguideline.com 10 - 20 m. Analytical measurements include spectrophotometric analysis or other types of detection systems (e.g., ion analysis if salt is a tracer). The quantity of dye penetrating into a CCS depends on several factors (e.g., applied pressure, vacuum, and absence of a gas) that must be understood and optimized to achieve adequate method sensitivity. and transmitted securely. Beginning with harvest of material from a bioreactor, downstream processing removes or reduces contaminants to acceptable levels through several steps that typically include centrifugation, filtration, and/or chromatographic technologies. The solution in these defective ampuls is adulterated and may be dangerously contaminated. The fill volume can play an important role when the dye is more or less diluted. USP <1207>: The latest chapter of informational guidance on CCIT from USP implies that ingress methods are not preferred. The BioPhorum team believes based on many years of experience and experimentation that this implication unfairly depicts ingress methods. Samples then are exposed over specified time intervals to predefined vacuum and/or pressure challenge conditions. Several critical factors and parameters must first be considered and understood to adequately qualify a CCIT method. Isr J Med Sci. Federal government websites often end in .gov or .mil. The method is suitable for detecting leaks with a size of at least approx. [2] Role of intraoperative esophagogastroenteroscopy in minimizing gastrojejunostomy-related morbidity: experience with 2,311 laparoscopic gastric bypasses with linear stapler anastomosis. Surfactants typically are added to a dye liquid to reduce its surface tension. 10 - 20 m. Within the pharmaceutical industry, the CCIT technology landscape is changing rapidly, and new technologies are emerging to create a wide range of testing methods and applications. [4] Common side effects include headache, vomiting, confusion, shortness of breath, and high blood pressure. Test Method Ph.Eur. The specifics of a test methods development rely on the purpose of that test, what it is intended to demonstrate, and the product and presentation to which it is being applied. International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use: Geneva, Switzerland, 1994, CPMP/ ICH/381/95. Accessibility Soil Testing Instruments. Factors and Parameters 3.2.9 recommend application of vacuum pressure for 10 min, and ISO 8362 (10) has an application time of 30 min. Although many companies represented in the BioPhorum Operations Group (BioPhorum) fillfinish CCIT workstream currently have experience with new and/or more sensitive technologies, some practical,technical, and regulatory hurdles have prevented implementation of those technologies. Please enable it to take advantage of the complete set of features! Can anyone recommend a vacuum chamber to use for parenteral drug dye ingress testing? FOIA There are benefits to the use and implementation of new and more sensitive technologies as appropriate, but as a new technology is developed, should it influence regulatory guidance and expectations of the industry? Some tracer liquids visibly fade or adsorb/absorb onto package surfaces over time. Sci. Before sharing sensitive information, make sure you're on a federal government site. Get Quote. The dye solution consists of deionized water, methylene blue dye at approximately .003% w/v, and trisodium phosphate (the latter used to simplify rinsing the ampuls after the dye test). A "leaker" ampul of *[purged]* {{Registered Trademark}} (Meperidine Hydrochloride) colored blue from the dye solution was collected as an exhibit during a recent BUF-DO EI (Albany Resident Post). With the optionally available PLUS control unit, testing is even easier and more standardised. Martin, Eric W.; Mack Publishing Co., (1965). In the lower gastrointestinal tract, where bacterial load is generally higher, the dye can indicate leaks, only if extended intestinal passage after oral ingestion is avoided. Positive controls demonstrate that a method is executed as intended, the method equipment functions properly during testing, the method has the necessary sensitivity, (e.g., detection of 20-m diameter defects), and other method parameters are set appropriately as validated. 3.2.9 USP 31 <381> Modified USP/PhEur ISO Modified ISO Dye Solution 1 g/L (0.1% w/v) Methylene Blue Aqueous Solution 1 g/L (0.1% w/v) Methylene Blue Aqueous Solution 0.1% w/v Methylene Blue Aqueous Solution 0.1% w/v Methylene Blue Aqueous Solution Vacuum -27 kPa -37 kPa 75 5 kPa1 63 kPa2 Limited visibility to headspace and/or masking effects from device parts affecting headspace analysis.

Cross-Industry Survey Data and Widespread Use: BioPhorum has conducted a cross-industry survey of CCIT methods currently applied across product lifecycles (unpublished data at time of writing; results of the survey to be published). Information and data from this study was . A leak detection instrument designed for testing pharmaceuticals with the Methylene Blue Dye Test Method, a test mainly used for testing blister packaging. HHS Vulnerability Disclosure, Help The test also must be appropriate to the product and to the manufacturing process that makes it. Some challenges with using the method remain. In the end, the objective of CCIT should be to demonstrate the integrity of a containerclosure system (CCS), assuring product quality and patient safety. PDA J. Pharm. Different pressure parameters are required to develop a dye ingress method with the same sensitivity as rigid containers. During qualification of a spectrophotometric measurement assay, you could establish a relationship between the concentration of a dye in the product solution and the leak size to which it correlates. Key questions to be answered include whether current methods provide the information and assurance required by a given container, product, and development stage. +49 (0)2302 8901- 0Fax +49 (0)2302 8901- 3, Data Protection Declaration in accordance with GDPR, Moisture Measurement / Dew point analysers, Overview - Moisture Measurement / Dew point analysers, Package Leak Detector LEAK-MASTER EASY PLUS, Leak Detection LEAK-MASTER MAPMAX Compact, Dome Pressure Regulators - Plant Engineering, Dome Pressure Regulator 737LE/S, complete solution, Dome Pressure Regulator 737LE/S-ES, complete solution, Dome Pressure Regulator 737LE-HD/S, complete solution, Dome Pressure Regulator 737LE-HD/S-ES, complete solution, Dome Pressure Regulator 737LE-HD/S CO2, complete solution, Dome Pressure Regulator 737LE-HD/S-ES CO2, complete solut, Dome Pressure Regulator 747LE/S, complete solution, Dome Pressure Regulator 747LE/S-ES, complete solution, Dome Pressure Regulator 757LE/S, complete solution, Dome Pressure Regulator 757LE/S-ES, complete solution, Dome Pressure Regulator 767LE/S, complete solution, Dome-Pressure Regulator 767LE/S-ES, complete solut, Safety Block for Dome Pressure Regulators, Maintenance Set Dome Pressure Regulators - Brass, Maintenance Set Dome Pressure Regulators - Stainless Steel, Maintenance Set 3'' Dome Pressure Regulators, Pressure Regulating Station Universal 704, Pressure Regulating Station 150N (acetylene), Pressure Regulating Station 150NF (acetylene), Pressure Regulating Station 150NA (acetylene), Pressure Regulating Station 386NGA (acetylene), Pressure Regulating Station 386NPL (O2/other technical ga, Pressure Regulating Station 684NG (acetylene), Pressure Regulating Station 684NG (O2/other technical gas, Pressure Regulating Station 684NGA (acetylene), Pressure Regulating Station 684NGA (O2/other technical ga, Overview - Spring-Loaded Pressure Regulators, for Pressure Regulators, Outlet Points, Inline, Overview - for Pressure Regulators, Outlet Points, Inline, Flashback Arrestor RF53N (Stainless Steel), Flashback Arrestor RF53N/H (Stainless Steel), Detonation Flame Arrestor/ Deflagration Volume Protector F53, Overview - with Pressure-Controlled Cut-Off Valve, Ball Valve with Female Thread - Acetylene, Ball Valve with Female Thread - Natural Gas, LPG, Inert Gas, Air, Ball Valve with Female Thread - Oxygen PN 10, Ball Valve with Female Thread - Oxygen PN 40, Ball Valve with Flanged Connection - PN 25, Ball Valve with Flanged Connection - PN 40, Seamless cut-in of back-up supply sources, Dome Pressure Regulators in industrial plants, Dome Pressure Regulators for optimum emptying of gas tanks, Dome pressure regulator HD for welding gas mixtures supply, Safety Relief Valves in Additive Manufacturing, Take-back of electrical appliances 19 ElektroG3.

As we rush toward the uptake of new technologies, we must accept that older, well-understood methods stillcan be used for CCI testing. 2022 BioProcess International All Rights reserved, Dye Ingress Methods for ContainerClosure Integrity Testing: An Industry Position Paper, Novartis cuts 275 jobs at its IL plant to consolidate Zolgensma production, Charles River ups cell therapy production with Memphis expansion, Drug Development Developing Biologics for Respiratory Delivery, Video news: Tosoh launches multi-column chromatography tech at CPhI, Gradual capacity rollouts reducing lead times, says Thermo, Benefits of Hollow Fiber Filter Cell Expansion. The same method is applicable for different testing points in a product lifecycle. Detection UV and Visual: For tracer liquids to be detectable (visible)inside a test sample, dye needs to be dissolved in the product liquid. Regulatory authorities are familiar with the dye ingress test, and regulatory expectations regarding expected method sensitivity are available in the public domain. Liquid ingress is the primary and practical mode of microbial ingress. The test is done by placing the pack of blister into a container of vacuum leak detector which has been filled with methylene blue dye mixed with water. A container must be transparent and exterior surfaces free from labels, dirt, and residual dye for visual inspection or spectroscopic analysis (if directly through a container). Characteristics of the product liquid (e.g., protein concentration) or cake (e.g., hygroscopicity) in a test sample. Direct correlation to microbial CCI (mCCI) potentially under the same conditions is possible. The method is suitable for detecting leaks with a size of at least approx. Guidelines detailing the initial CCI qualification and validation requirements have been defined and can be found in the US Pharmacopeia chapter 1207 (USP<1207>) (1). Note: About 5 ml of 0.1 % Methylene Blue solution to be used. A lower surface tension potentially enhances the detection of defects and smaller leaks because it improves the wetting properties of a package surface. Leak Tester works on the principle of creating a negative pressure in a closed chamber which inflates the sealed pouches due to pressure and leaked pouches don't inflate. Authors D M Sensenig, H C Jurgeleit. It is evaluated and stressed throughout the manufacturing lifecycle of a sterile drug product (e.g., during primary package development, line qualifications, product manufacturing qualifications, stability testing, change-control process, and shipping studies) and tested when required. Those benefits are the primary reasons why dye ingress is the most commonly used method to support process characterization and validation of parenteral products and as a test method to demonstrate integrity of a CCS during product stability.

Tracer Liquid (Dye) Choice and Surfactant Use: For dye ingress testing, USP and the International Standards Organization (ISO) suggest a dye (e.g., methylene blue) at a concentration of 0.1% w/v (1 g/L). Disassembly also can pose a risk to operators. With the ELT-201P Electrolab launches the first and only smart verification of leak detection using the widely accepted and cost efficient blue dye method. Leak tests using a blend of MB and ICG appear to be more sensitive for small defect detection of gastrojejunal anastomoses during robotic gastric bypass surgery. Decreasing anastomotic and staple line leaks after laparoscopic Roux-en-Y gastric bypass. Although the ingress method involves probabilities (e.g., formation of air pocket in a void), development of method parameters are such that those probabilities are not an issue in the range of the method being used. Surfactants typically are added to a dye liquid to reduce its surface tension. Packaging and storage Preserve in well-closed containers. Discussion: Methylene blue can reliably be used as routine diagnostic test for the assessment of upper gastrointestinal integrity, where bacterial load is low. Diffusion Cell. As soon as the negative pressure in the test chamber is equalized again, a negative pressure prevails in the leaking blister through which methylene blue liquid is drawn in. 10 ISO 8362 Injection Containers and Accessories. Haddad A, Tapazoglou N, Singh K, Averbach A. Obes Surg. Two additional time-dependent aspects of a tracer liquid ingress test method that should be considered are the relaxation time and the hold time between test execution and final inspection. Many technologies are used to characterize biological products, manufacturing processes, and raw materials. Regardless of the mechanism of action, leaker ampuls colored by methylene blue with trisodium phosphate, can become colorless when subjected to light. As a physical limit test method thats part of a well-defined and executed holistic approach to CCI, dye ingress testing can provide equal product quality and safety assurance for package-seal integrity with respect to microbial contamination, compared with the application of deterministic methods (1). General Considerations: Any CCIT method, including dye ingress, should be qualified or validated appropriately for its intended use based on available scientific knowledge. Validation of a CCI procedure should include the LoD for dye penetration in the specific drug product configuration. Ingress methods have shown that they can demonstrate readily the required sensitivity and robustness needed in our industry today. [4] Other side effects include serotonin syndrome, red blood cell breakdown, and allergic reactions. To this, add one drop. A number of test parameters play an important role during the performance of ingress testing and can influence the sensitivity and probability of detection of leakages. 5.4 Close the lid of the desiccator properly. Purpose In our experience, other important factors include variability/precision and repeatability/reproducibility. Ultimately, choosing the best method for challenging CCI should be based on individual product characteristics. Clearly, results show that the bioindustry uses considerably more stringent and aggressive conditions than those outlined in the guidance documents. 1 USP <1207> Package Integrity Evaluation Sterile Products. In a sterile tube, transfer 5.0 ml of yeast suspension aseptically. 7 Li L. Container Closure Integrity Testing Method Development and Validation for Prefilled Syringes. Abstract. The standard protocol for MB is to use the peak at 664. The positive controls were immersed in 1g/L of methylene blue dye solution, . Bookshelf We agree that dye ingress or other such methods might not be appropriate for all products or presentations (for example, products that are sensitive to presence of oxygen). In most cases, that is not possible without creating a high risk of altering the CCI of a primary container (and creating false positives as a result of removing it from an assembled device). Exposure to fluorescent light caused some ampuls to go completely colorless in 2 hours, while others had only a partial loss of color from blue to pale blue in an 8 hour period. When and When Not to Use the Dye Ingress Method The method must be right for each specific container and product. Eur. The BioPhorum Operations Groups (BioPhorum) mission is to create environments where the global biopharmaceutical industry can collaborate and accelerate their rate of progress for the benefit of all. Response to the Publication of USP <1207>. It uses methylene blue dye or another colored chemical liquid to determine whether there is a leak or not. 2. It is important to note that, based on what a primary container needs to maintain (e.g., sterility, protection, a critical headspace, or vacuum), dye or microbial ingress may not be the correct means of ensuring CCI.
