Design Space Definition
• For each unit op establish functional relationships of CPP and CQA of input materials with CQA of output materials– e.g. disintegration time ~ compression force and
hydrophobicity• Establish interactions between unit ops
– e.g. hardness ~ PSD and compression force• Establish design space boundaries by propagating
backwards limits imposed on final product CQAs

• Considered– Degradation
• NMT 0.4 mole % lactam– Hardness
• NLT 3 kP– Weight variation
• 90 % - 110%• % RSD NMT 6%
• DS definition for 15 CPPs• Interactions were established for some CPPs
– one or more slides included to describe those interactions
• There were no significant interactions for few CPPs– ranges for those are shown in slide 18

Summary
• Risk Assessment helps to identify CPP• Preliminary Design Space is defined by backward
propagation• Some PPs identified by RA are not critical in the
explored experimental domain• Preliminary Design Space is constructed for:
– Wet granulation– Fluidized bed drying– Blending– Tabletting
• Some interactions between unit ops were considered– Tabletting and intermediate CQA– Fluidized bed drying and tabletting– Wet granulation and tabletting
