The trial was terminated by Hyperion Therapeutics, which said on Sunday it would stop developing the drug after discovering manipulation of trial data by employees of a recently acquired subsidiary, Andromeda Biotech.
Along with the non-cash impairment, Evotec said it had open receivables of 3.4 million euros outstanding due from Hyperion and Andromeda, which it would need to meet its 2014 profit targets.
