ACR Image Metrix Presents Validation Methodology at DIA Europe

PHILADELPHIA(BUSINESS WIRE) Brenda K. Young, BA, CCRA, senior director of clinical operations at ACR Image Metrix?, an imaging contract research organization (CRO) located in Philadelphia, Pennsylvania, has presented her experience in computerized system validation to the Drug Information Association (DIA) 3^rd Annual Clinical Forum held in Nice, France, on October 19, 2009.
Young's presentation topic, A CRO's ChallengeValidating Leading Edge Software for Imaging Clinical Studies,? discussed how conducting imaging clinical trials often involves leading edge software. Computerized systems used in clinical investigations, imaging workstations and software are required to be validated before data is collected in support of regulatory submission. During her presentation, she presented two case studies that described approaches to computer system validation.
Imaging, as a part of a clinical trial, can involve many different modalities for research; technical validation is a key component of high importance for its usage in a trial whose data will be used to support a regulatory submission. Understanding the work process simulated by testing is key to the performance qualification portion of computer software validation. Knowledge of the mathematics and physics underlying the software and workstation is not necessary to execute a good validation; however, it is critical to possess knowledge of the work process with the computerized system,? Young explained.
Brenda is an example of the high caliber imaging expertise on staff at ACR Image Metrix. She brings over 25 years of clinical research experience to our team and is on the forefront of validation efforts for imaging clinical research in the industry,? stated Michael Morales, general manager for ACR Image Metrix.

Proteomics and Validation

PFA-Proteomics Contract Research Services

The Proteome Factory is specialised in contract research for differential proteome analysis (proteomics, differential protein display) studies, identification and validation of regulated proteins, biomarkers and targets from all kind of protein containing samples. Only proteome analysis gives new insights in quantitative regulation of proteins caused by internal and external factors like diseases and drugs. The identification of regulated protein species (name, amount and modification) is the prerequisite to understand functional protein networks and their correlations. Biomarkers, biomarker profiles and targets can be identified. The proteomics information can be used to get better insights in in-vivo and in-vitro pharmacology or for optimization of fermentation processes and plant breeding.
For this purpose Proteome Factory has developed a comprehensive PFA-Proteomics Platform which opens new opportunities in biomarker and protein target discovery, quantification, identification and validation as well as pharmacokinetics of protein drugs. The proteomics platform consists of sophisticated gel-based and gel-free proteomics methods like iTRAQ™* proteomics and proprietary proteomics technologies ile MeCAT. In each proteomics study Proteome Factory decides in close cooperation with its partners and clients which proteomics technologies of the PFA-Proteomics Platform should be used to meet the scientific requirements. The study design, optimized sampling of biological material, sample prefractionation (e.g. affinity depletion of abundant plasma/CSF proteins) as well as statistical requirements are very important to ensure a high quality and valuable proteome study.

Extreme High Resolution 2D Electrophoresis

Proteome Factory’s extreme high resolution two dimensional gel electrophoresis (2DE) based on the 2DE development of Professor Klose (Klose and Kobalz, Electrophoresis, 1995, 16, 1034-59) is still the most powerful separation technique for protein species worldwide allowing the best and most reliable proteome analysis. Several thousand protein spots (theoretically up to 10,000 protein spots depending on sample and gel size, up to 40x30 cm) can be separated and relatively quantified.
Even Proteome Factory’s 2DE gels with a size of 23x30 cm are much more powerful in protein separation than commercially available IPG-based 2DE because Proteome Factory’s 2DE technique has several advantages:
1. significant better protein separation resolution,
2. higher sensitivity with less protein amount,
3. less artificial streaks,
4. separation of basic protein up to pH 10.5 (up to pH 11.5 in 60x30 cm gels) and
5. high compatibility to protein identification by MS.

The Importance of Clean Analytical Instrumentation Systems in Pharmaceutical Process Validation

by Dave Simko, Swagelok (Full-length paper presented at Interphex) Validated pharmaceutical processes are necessary to ensure quality of the products being manufactured, establish and maintain effective costs, and meet the regulatory requirements that are mandatory for approval and introduction of new pharmaceutical products. The collection of data needed to document the effectiveness and repeatability of the pharmaceutical process requires the use of a variety of both process control and analytical chemistry instrumentation. Process control instrumentation monitors process variables, such as pressure, temperature, level, and flow in a manner typical of chemical processes. The main difference in process control instrumentation for pharmaceutical processes is in the interface between the sensing element or device and the clean process stream. Analytical chemistry instrumentation monitors the chemistry of the process throughout the manufacturing process. It is especially important during the purification, compounding, and formulating of the finished product. Sample collection and conditioning—prior to introduction into the analytical instrument—is critical to reliable analysis, in both laboratory devices and in at-line and on-line analyzer systems. The cleanliness of the sampling system is an important element of reliability and repeatability. Cleanliness is impacted by the design, manufacture, and condition of the fluid control components used in the system. Consideration must be given to potential inboard, outboard, and internal leakage; effective sealing systems; entrapment; material selection; surface finishing and conditioning; and cleanability. The result of these considerations is an evaluation process that will lead to selection of the analytical chemistry instrumentation system components that will optimize repeatability and make validation easier. Component Selection Process Proper selection of components for service in clean systems is the responsibility of the system designer. Following are some elements for consideration in the selection process: Design Choose components that have proven leak-tight performance capabilities, considering potential for inboard, outboard, and internal leakage. Consider the seals used in the design. Select components with sealing systems that will meet the system’s service conditions. Look at the potential for entrapment and select components designed to minimize entrapment areas. Study the flow path through the component. Consider the component with the smoothest flow path and minimal internal volume. Consider the materials of construction and of the seal members. Be certain that they will be compatible with the pressure, temperature, and media requirements of the system. Check all ratings for compatibility with system requirements. Manufacture Check surface finishes. Components with the best surface finishes will be easier to clean and keep clean. Consider how the components are assembled and the possibilities for entrapment. Determine if the lubricants used will be compatible with the system. Cleaning Study the cleaning method used by the manufacturer and select components that will meet the system requirements initially and in service. Verification Determine what certifications will be required to verify the necessary elements of the specification or procurement document. Packaging Specify the packaging method that best meets the need of the end user.

Updated guidance on requirements for paediatric 'compliance checks' during validation

We have previously published guidance on how the MHRA will handle the impact of the requirements of the Paediatric Regulation on the validation of applications for marketing authorisations (MAs). The guidance has been updated to reflect the need for compliance checks on certain line extensions and variations as well as initial applications for new medicinal products.
The same principles apply in these cases and the MHRA will continue to request an opinion from the European Paediatric Committee where one has not already been obtained by the applicant. The document has also been updated to refer to the final European Commission guideline on the content of applications for paediatric investigation plans and the operation of the compliance check and also to other European Medicines Agency (EMA) and Co-ordination Group for Mutual Recognition and Decentralised Procedures (CMDh) guidance.
