Thanks for your reply.

❝ ❝ We have conducted a pivotal study for Europe with 48 subjects considering ~80% power, ISCV: 23%.

❝ ❝ The study was bioequivalent and 90% CI is within 80-125 for both Cmax & AUCt.

❝ ❝ Power of Cmax and AUCt are 92% & 66% respectively.

❝

❝ In this order? Can you give us their CVs and GMRs?

CV- Cmax: 27.731; AUCt: 22.678

GMR-Cmax: 97.76; AUCt: 87.99
