Unfortunately, SRPT probably cannot risk that the continuing tox brought on by Protensa will be mistakenly attributed to SRPT. I would say those boys are probably stuck until full approval and cannot be part of Phase III whatever the context of Phase III. Regretable, but probably true. MDA certainly seems to have backed the wrong horse.
MDA's suport has been anywhere from nonexistent to questionable for SRPT. They should be ashamed to have put their jobs and political agenda ahead of the boys, and the science. I hope they crumble and go away because they have lost their ability to put the boys best interests ahead of their own.
