What was measured

ClinRO is a clinician reported assessment which measures a participant's EB hair loss. It is comprised of 4 category response options: 0 = EB have full coverage and no areas of hair loss; 1 = There are minimal gaps in EB hair and distribution is even; 2 = There are significant gaps in EB hair or distribution is not even; 3 = No notable EB.

Analysis population: All randomized phase 3 participants with baseline ClinRO measure for EB Hair Loss ≥ 2 and who had evaluable data for this outcome measure. A Non-responder Imputation (NRI) was applied for participants with missing data at the timepoint due to discontinuation or other intercurrent events.
