The most expensive CMC problems are the ones you find too late.
A titer issue caught at IND is a headache. The same issue caught in tox is a disaster. Most CMC teams spend their energy reacting — to a failed batch, a comparability gap, a regulatory question that should have been answered two stages ago.
What “right the first time” actually looks like.

Our guide maps the failure points that quietly derail programs — from analytical methods that don’t scale, to comparability gaps found in tox — and how to design them out before they cost you months. Good CMC isn’t reactive. It’s preventive.
