IPQ Special Report — March/April 2008 in Review

THE CHALLENGES IN CONTROLLING EXTRACTABLES AND LEACHABLES are driving drug and biologic manufacturers and their vendors to explore new ways of comparing experience and sharing information. As product, process, packaging and delivery materials and systems evolve and their interactions grow more complex, industry is looking for pathways to make the E&L evaluation process more efficient and effective, and new collaborations are being formed that reach across the supply chain and the product lifecycle. Regulators, in turn, are voicing support, offering the new quality-by-design concepts as guideposts. Having put forth inhalation/nasal product E&L recommendations, the Product Quality Research Institute is now focusing on parenterals and ophthalmics. Other manufacturer and vendor collaborations are developing an E&L database and/or best practices to help simplify the evaluation process. Sensitive products and complex processes heighten the challenges in the biotech context.
