Thanks for the link - that clears up a lot for me as these trials have different parameters and qualifiers. Maybe some of you gals are right for one of the other two - guess you would have to come to Seattle for these shots as they also take blood and probably want to check the shot site and other things that you would need to be "on the spot" for.
One trial is for NED and one for NED/"stabilized" - one for stage 2/3 and one for stage4. You may even have friends that would benefit if you can not.
