Study Endpoints

Primary Endpoints

Percentage of Participants With At Least a 20% Reduction in Alkaline Phosphatase (ALP) or Normalization of ALP at Week 12 Compared to Baseline
Baseline and Week 12

Percent change was calculated as \[(ALP at Week 12 - ALP at Baseline)/ALP at Baseline\] \*100. The participant was considered to have successfully achieved a 20% reduction in ALP if the result was ≤-20. The participant was considered to have successfully achieved ALP normalization if ALP was abnormal at Baseline and normal at Week 12.
