Potency of biotherapeutics, often determined by cell-based assays, is one of the most important critical quality attributes. Potency must be monitored throughout the entire drug development cycle as it measures drug activity and provides a direct link to clinical efficacy. An ideal potency assay should represent a drug’s mechanism of action (MOA), as well as be specific and sensitive enough to detect changes and degradations of the product. Cell-based potency assays are intrinsically complex and may present challenges during development, validation, transfer and implementation.
This presentation will highlight the approaches used in developing consistent cell-based potency assays meeting regulatory expectations (USP <1032> and <1033>) and are suitable for cGMP stability testing. In addition, a phase appropriate potency method development and qualification/validation strategy will be discussed. Practices in support of successful cell-based assay transfer and long-term maintenance of the assay in the QC laboratory will be presented.
The discussion will include:
- Challenges in establishing a robust cell-based potency assay
- Routine assay performance monitoring
- Analyst training and qualification requirements
- Analytical working cell bank generation and characterization
- Cell maintenance and growth tracking
- Bridging studies for critical reagents
