Potency and the product life‐cycle<br />
(additional points)<br />
• As clinical development progresses, the<br />
measure or measurement of potency may<br />

characteristics are likely to correlate with<br />
clinical benefit. This understanding will evolve<br />
during the course of clinical development.<br />
