What researchers measure

Primary outcomes

  1. frequency of dose limiting adverse events

    Time frame: 7 days

  2. Stroke recovery based on global test analysis including modified Rankin Scale (mRS), NIHSS, and Barthel Index (BI)

    Time frame: 90 days

Secondary outcomes

  1. proportion of subjects with a mRS score of less than or equal to 2

    Time frame: 90 days

  2. change in functional outcome throughout range of mRS scores

    Time frame: 90 days

  3. changes in outcome measures (mRS, NIHSS, BI) over time

    Time frame: 365 days

  4. proportion of subjects with an excellent functional outcome

    * mRS score = 0 to 1; and * NIHSS score = 0 to 1; and * Barthel Index score = greater than or equal to 95

    Time frame: 90 days

  5. frequency of adverse events

    Time frame: 365 days

  6. change in vital signs

    Time frame: 365 days

  7. change in safety labs

    Time frame: 365 days

  8. frequency of secondary infections

    Time frame: 365 days
