Dear Helmut,

❝ What were the CVs actually?

❝ • Published one(s)

Typically in mid-40 range (ibandronate)

❝ • Your pilot study

Internal data showed mid-twenties

❝ • Your pivotal study

Our study showed 26.1

❝ ❝ Having read your presentation, I can see why pilot info isn't all that

❝ ❝ great for sample size estimation.

We've attempted sequential design for other products. This option was not really available 4-5 years ago.

Thanks for all your feedback.
