iAUC of the Change From Baseline in mMRC-10 Sum Score
大体时间:Up to 16 weeks
The Modified Medical Research Council (mMRC)-10 sum score assesses muscle strength of 10 muscles groups, both sides (left and right). A score between 0 (paralysis) and 5 (normal strength) is assigned for each muscle group. A higher value indicates better muscle strength. The total score, ranging from 0 to 100, is based on the sum of both the left and right side of the body. The Incremental Area Under Curve (iAUC) is the area under the curve of the change from baseline in the Modified Medical Research Council (mMRC)-10 score. A positive AUC indicates a favorable outcome while a negative AUC indicates an unfavorable outcome.

Change From Baseline in the Average Score of the 2 Most Important Muscle Groups as Assessed by the mMRC-14 Sum Score
大体时间:At week 16
The Modified Medical Research Council (mMRC)-14 assesses muscle strength of 14 muscles groups, both sides (left and right). A score between 0 and 5 (normal strength) is assigned. This endpoint is the change from baseline in the average score of the 2 most important muscle groups affected by the disease. It ranges between 0 and 5. A change of more than 0 represents an improvement in strength, and a change less than 0 represents worsening.
At week 16
Change From Baseline in the mMRC-14 Sum Score
大体时间:At week 16
The Modified Medical Research Council (mMRC)-14 scores range from 0 to 140 with a higher score representing better muscle strength. A change of more than 0 represents an improvement in strength, and a change less than 0 represents worsening.
At week 16
Proportion of Participants Showing a Deterioration of at Least 2 Points as Assessed by the mMRC-10 Sum Score
大体时间:Up to 16 weeks
The Modified Medical Research Council (mMRC)-10 scores evaluates motor strength/weakness from 10 predetermined muscle groups. A higher proportion of participants showing a deterioration represents a worsening of the outcome.

大体时间:Up to 16 weeks
Measurement of grip strength (GS) has been done using the Martin vigorimeter in kPa. The incremental Area Under Curve (iAUC) is the area under the curve of the change from baseline of GS daily average. The 3 daily measurements of GS from the left hand and the 3 daily measurements of GS from the right hand have been recorded and the daily average for the left hand and right hand has been calculated, respectively.

Measurement of grip strength (GS) has been done using the Martin vigorimeter in kPa.

The 3 daily measurements of GS from the left hand and the 3 daily measurements of GS from the right hand have been recorded and the daily average for the left hand and right hand has been calculated, respectively. A 3-day moving average has been generated based on the average over the last 3 days of the obtained daily averages for each hand.
