| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Change From Baseline in Total Daily Physical Activity (Counts Per Minute) to Week 10-12 | Baseline, Week 10-12 | Daily physical activity was measured by actigraphy in participants with sickle cell disease (SCD) and chronic moderate anemia. Actigraphy assessments were performed using wrist-worn tri-axial accelerometry device. Actigraphy is an accepted methodology for tracking activity levels, time spent in moderate and vigorous physical activity, step counts, and energy expenditure. Change from baseline to follow-up visit was calculated as the baseline measurement subtracted from the follow-up measurement for all assessments. In this outcome measure the average of at least 8 valid days during the specified two-week period was considered. A participant's daily wear must be 18 hours or more in a day to be considered a valid day. |
| Primary | Change From Baseline in Total Daily Physical Activity (Counts Per Minute) to Week 22-24 | Baseline, Week 22-24 | Daily physical activity was measured by actigraphy in participants with SCD and chronic moderate anemia. Actigraphy assessments were performed using wrist-worn tri-axial accelerometry device. Actigraphy is an accepted methodology for tracking activity levels, time spent in moderate and vigorous physical activity, step counts, and energy expenditure.

| Primary | Change From Baseline in Light Physical Activity to Week 10-12 | Baseline, Week 10-12 | Change in daily physical activity was measured by actigraphy in adolescent and adult participants with SCD and chronic moderate anemia. This outcome measure described the change from baseline in light physical activity. Change from baseline to follow-up visit was calculated as the baseline measurement subtracted from the follow-up measurement for all assessments. In this outcome measure the average of at least 8 valid days during the specified two-week period was considered. A participant's daily wear must be 18 hours or more in a day to be considered a valid day. |

In this outcome measure the average of at least 8 valid days during the specified two-week period was considered.
