Using Analytical Platform Technologies to Support Accelerated Product Development-Concept Review and Case Study.

The number of products being developed for serious conditions that are eligible for expedited programs has been increasing in recent years. This article presents an industry perspective on how to reduce analytical life cycle steps when using analytical platform technologies (APT) in support of accelerated biological product development. Strategies for life cycle steps for APT methods are conceptually reviewed within the framework of supporting chemistry, manufacturing, and control (CMC) development acceleration. Reduced method qualification, transfer, and validation studies could be performed, provided that the initially validated test method remains unchanged. A detailed case study is used to illustrate considerations for the initial method validation and subsequent APT verification studies. Considerations for APT implementation are discussed and suggestions are provided for the submission of APT information in regulatory filings.

PCMO L01-Setting Specifications for Biological Investigational Medicinal Products.

UNLABELLED: This paper provides overall guidance and best practices for the setting of specifications for clinical biological drug substances and drug products within the framework of ICH guidelines on pharmaceutical development [Q8(R2) and Q11], quality risk management (Q9), and quality systems (Q10). A review is provided of the current regulatory expectations for the specification setting process as part of a control strategy during product development, pointing to existing challenges for the investigational new drug/investigational medicinal product dossier (IND/IMPD) sponsor. A case study illustrates how the investigational medicinal product specification revision process can be managed within a flexible quality system, and how specifications can be set and justified for early and late development stages. LAY ABSTRACT: This paper provides an overview for the setting of product specifications for investigational medicinal products used in clinical trials. A case study illustrates how product specifications of investigational medicinal products can be justified and managed within a modern product quality system.

Characterization of the initial level and migration of silicone oil lubricant in empty prefilled syringes for biologics using infrared spectroscopy.

Glass prefillable syringes are lubricated with silicone oil to ensure functionality and a consistent injection for the end user. If excessive silicone is applied, droplets could potentially result in aggregation of sensitive biopharmaceuticals or clouding of the solution. Therefore, monitoring and optimization of the applied silicone layer is critical for prefilled syringe development. The hydrophobic properties of silicone oil, the potential for assay interference, and the very small quantities applied to prefilled syringes present a challenge for the development of a suitable assay. In this work we present a rapid and simple Fourier transform infrared (FTIR) spectroscopy method for quantitation of total silicone levels applied to prefilled syringes. Level-dependent silicone oil migration occurred over time for empty prefilled syringes stored tip-up. However, migration from all prefilled syringes with between 0.25 and 0.8 mg of initial silicone oil resulted in a stable limiting minimum level of between 0.15 and 0.26 mg of silicone in the syringe reached after 1 to 4 years of empty tip-up storage. The results of the FTIR assay correlated well with non-destructive reflectometry characterization of the syringes. This assay can provide valuable data for selection of a robust initial silicone oil target and quality control of prefilled syringes intended for biopharmaceuticals.
