Emerging Technology Trends in Biologics Development: A Contract Development and Manufacturing Perspective

by , , , , and

For a contract development and manufacturing organization (CDMO), process development and manufacturing of recombinant proteins must be linked because of tight timelines driven by client expectations. Those are in turn driven by a need for rapid progression to clinical testing. Early in process development, the choice of raw materials needs to reflect existing supply chain and manufacturing infrastructure, but remain suitable for scaling up to meet future needs. One approach is to establish platform processes for a class of molecules…

Rapid Development and Scale-Up of Biosimilar Trastuzumab: A Case Study of Integrated Cell Line and Process Development

by , , , , and

Compared with that for new drugs, biosimilar development faces significantly condensed timelines from cell line to first-in-human (FIH) trials. A biosimilar development program needs to accelerate quickly toward preclinical and phase 1 studies; phase 2 studies typically are not required because dose response and other patient-treatment concepts are already established by the original, comparator medicine. Phase 3 studies typically are limited to fewer patients, which ultimately shortens overall timelines and costs. The key challenge remains: demonstrating comparability and high similarity…

New Paradigms for Process Validation: A Practical Approach

by , , , , , , , , , , , and

Both the United States and the European Union offer guidance on a life-cycle approach to process validation. This goes beyond the traditional three to five lots run at the center point of proposed ranges for operating parameters. New approaches leverage product design and process development information. They facilitate adapting the QbD paradigm to allow for a science- and risk-based selection of critical process parameters, key process indicators, and appropriate specification criteria. The number of runs for process performance qualification (PPQ)…
