Situation

A mid-sized pharmaceutical company was developing a new treatment for a neurodegenerative rare disease. 

Given the promising finding from the phase 1 study, the company decided to skip phase 2 and to start a phase 3 study with limited information.​

The planned COA (a PerfO measure) for the primary endpoint was not developed for clinical trial use, it was unclear how much change is considered clinically meaningful.

AESARA member was tasked to define the COA effect size to inform the Phase 3 trial sample size. ​
