** Biotech co's shares VCNX.O fall 63% to $2 premarket;
set to touch their record low and set for worst day ever
** Co says its lead clinical candidate, pepinemab, to treat
patients with early signs of Huntington's disease, did not meet
its main goal in a mid-stage trial urn:newsml:reuters.com:*:nGNX20YXlz
** No statistically significant difference between the
placebo and pepinemab-treated groups, possibly due to small
group size in this phase 2 study - VCNX
** However, co says results from two cognitive assessments
showed beneficial changes in planning ability and memory
associated with disease progression
** "We believe the data, therefore, suggest that patients at
a somewhat more advanced stage of Huntington's disease may
derive the greatest benefit from pepinemab" - CEO
** Co says it expects to begin enrolling patients this month
in a new Alzheimer's disease study of pepinemab
** Up to Monday's close, stock rose ~13% YTD
