Just a little confused by note 5 to the half-yearly report.
"as a result of these factors there exists a material uncertainty on the groups ability to continue as a going concern."
"additional funding will be required to conduct further Phase III trials"(should the Directors be of the view in the future that the development of ATC should continue).
Is this a cause for concern or am I just worrying unnecessarily.
Cheers
