trials are usually single level
I have looked into trial here in the US. They only one I found for the new m6c, which is supposidly now closed to any new participants, was only for single level. You see, they do not want anything to place a higher chance of a negative out-come for their trial. It will be a long wait here and if one is already talking adr, they usually can't wait to long.
