The NIHSS is a systematic assessment tool that provides a quantitative measure of stroke-related neurologic deficit. Scores for the NIHSS range from 0 to 42, with 0 representing no symptoms and 42 representing death.

The mRS measures independence, rather than neurologic function, with specific tasks pre- and post-stroke, respectively. The scale consists of 7 grades, from 0 to 6, with 0 corresponding to no symptoms and 6 corresponding to death. The distribution of mRS scores was summarized at each timepoint. An excellent outcome on the mRS was defined as a score of 0 or 1, while a good outcome was defined as a score of 0, 1, or 2.

The Barthel Index consists of 10 items that measure a person's daily functioning, specifically the activities of daily living and mobility, and can be used to determine a baseline level of functioning and to monitor change in activities of daily living over time. The scores for each of the items are summed to create a total score up to a potential of 100, with higher scores representing a greater level of independence.

AE: any untoward medical occurrence that does not necessarily have a causal relationship with this treatment. SAE: any untoward medical occurrence that at any dose: results in death; in the view of the Investigator, places the participant at immediate risk of death (a life-threatening event); requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; results in a congenital anomaly/birth defect; any other medically important event that, in the opinion of the Investigator, may jeopardize the participant or may require intervention to prevent one of the other outcomes listed in the definition above. Events were categorized as severe, moderate, or mild, and related or not related to study treatment.
