Process Development

From cell culture through recovery and purification, the process scientists at Catalent Biologics develop processes that ensure consistent cGMP manufacturing performance and a reliable product supply. The use of identical bioreactors and controllers throughout development and manufacturing enables a smooth transition from non-GMP to GMP manufacturing. Comprehensive, integrated analytical testing ensures product quality attributes are maintained throughout the process.

UPSTREAM DEVELOPMENT

The process development team at Catalent is equipped to work with GPEx® or external cell lines.  During upstream development, an optimum process is developed to maximize product titer with the correct Quality Target Product Profile (QTPP).  Media and feed strategies and other process parameters are evaluated using DoE methods.  Once established at small scale, the processed is scaled up in preparation for GMP manufacturing.  Material is generated for the following:

  • Identify master cell bank candidates
  • Downstream process development
  • Intermediate Reference Standards
  • Start of analytical qualification
  • Product quality characterization
  • Optional formulation and stability studies
  • Non-GMP engineering/tox runs

DOWNSTREAM DEVELOPMENT

Purification development is based on three chromatography steps and multiple filtration steps to purify and concentrate the product. Once the process is optimized, large scale production and engineering runs confirm process performance at larger scale. Purified bulk drug substance undergoes full testing to confirm it meets specification anticipated for GMP material.
