Defining the target!<br />

� Initial target definition (before project start):<br />

� Characterize originator-batches with extensive<br />

set <strong>of</strong> state-<strong>of</strong>-the-art methods<br />

� Develop bioassays reflecting MoA<br />

� First risk-assessment to evaluate CQAs<br />

� Refined target (during project):<br />

� Characterize additional originator batches<br />

� Broad quality ranges obtained during cell line /<br />

process dev. allow establishment <strong>of</strong><br />

correlations phys.-chem. ↔ bioactivity<br />

� Refine definition <strong>of</strong> CQAs<br />
