I have a dumb question for the smart people out there. If we are doing a p2/3 trial does the entire trial last just the 48 weeks or does the p2b portion last 48 weeks or at a certain point say after 20 weeks it turns into the p3? Then the p3 goes on for 28 weeks. Or am I way off. I guess we will see this in the trial design once it is released. Any thoughts?
