Further study details as provided by Vernalis (R&D) Ltd:

Primary Outcome Measures:
  • To establish the safety of five dose levels (1.0, 2.5, 5, 7.5 and 10 mg/kg)of V10153 in patients with acute ischaemic stroke. [ Time Frame: Ongoing ]

Secondary Outcome Measures:
  • To compare recanalisation rates across dose levels. [ Time Frame: Ongoing ]
  • To compare clinical outcome between treatments by NIHSS, Modified Rankin Scale and Barthel Index. [ Time Frame: Post-study completion ]
