According the lawsuit, the IPO Registration Statement contained inaccurate
statements of material fact about the development status of drisapersen, the
drug's Phase II and Phase III clinical studies, and the prospects for
drisapersen's regulatory approval.Less than three months after the IPO,
Prosensa disclosed that drisapersen had not met the primary endpoint in the
Phase III study. According to the press release, "[t]here was no treatment
difference in key secondary assessments of motor function: 10-meter walk/run
test, 4-stair climb and North Star Ambulatory Assessment."On this news, the
value of Prosensa stock dropped 70%.
