** Co's experimental Alzheimer's treatment fails to show
statistical significance in meeting the goals of a mid-stage
trial

shown the drug led to statistically significant results, but it
only included a sub-group of patients - around 90 of the planned
325
** The drug, buntanetap, did not show statistical
significance in patients when measured using the ADCS-CGIC
method, which relies on both direct examination of the patient
by a doctor and interview of care providers
** Co expects to discuss the data with the U.S. FDA in the
next two to three months and then conduct a late-stage study
** Including session moves, stock down ~60% YTD
