Pre-clinical phase

Pre-clinical testing establishes that the target compound demonstrates the safety and efficacy necessary to advance to human testing. At this stage, in vitro and in vivo testing can require several years and if successful, leads to the preparation and filing of an Investigational New Drug (IND) application.

Process Development Considerations

  • Cell line development
  • Clone selection
  • Media and feed screening
  • Upstream process development
  • Master cell bank establishment
  • Downstream process development
  • Formulation development
  • Analytical methods development and optimization
  • Analytical process development support
  • Biosimilars comparability analytical programs

Cell Line Development Considerations

  • Clone choice – cell lines that can produce the biologic at a sufficient titer and quality
  • Robustness studies – studies that replicate scale-up conditions
  • Genetic stability – protein production and quality should remain stable after >60 generations of cells

Process Development Considerations

  • Process efficiency – eliminating wasteful steps and capacity utilization
  • Process viability – reproducibility through scale-up and tech transfer
  • Financial viability – balancing productivity with cost

Technology Considerations

  • Flexibility – single-use equipment enhances flexibility, templating, and rapid suite configuration, and reduces cleaning costs
  • Scalability – when choosing technologies at the earliest stages, such as scaling a bioreactor used for mammalian cell culture from 3 L to 200 L to 2000 L
  • Ease of use – solutions include pre-assembled sterile process flow paths; connectors that allow for aseptic connection, disconnection, and re-connection

Regulatory Considerations

  • Patient safety – clinical development milestones must assess safety and product effectiveness
  • Product quality and process robustness – data collection and analysis are needed to confirm
  • Filing strategy – knowing the countries where filing will happen should guide who inspects the manufacturing facility

Business Considerations

  • Speed to clinic – heavy investments are being made in research and development without returns
  • Process efficiency – proactively consider scale-up, not just initial speed
  • Filing strategy – identify the country to file in first and rapidly obtain access to the market
