- Type
- SECONDARY
- Title
- The Proportion of Subjects Who Achieved Success on the Investigator's Global Assessment (IGA)
- Description
The investigator's global assessment (IGA) is a five-point scale that is used for overall clinical assessment of severity of disease and classifies EBS-involved skin with a score ranging from 0-4. Success on the IGA was defined as ≥2-point reduction from Baseline to Visit 6 (Week 8).~IGA Scoring:~0 = Clear; 1 = Near Clear; 2 = Mild; 3 = Moderate; 4 = Severe~Minimum score = 0 Maximum score = 4; higher score = worse outcome
- Time frame
- Baseline to Week 8
- Population
All efficacy analyses were conducted using the Intent to Treat (ITT) Population that consisted of all randomized subjects who were dispensed study drug. Subjects were included in the treatment group to which they were assigned.
