The SF-36 health survey is a participant-reported survey to measure participant's health. It is a 36-item questionnaire used to measure 8 various aspects of health (vitality, physical functioning, bodily pain, general health perceptions, physical role functioning, emotional role functioning, social role functioning, mental health).

All data collected during ACT13739 and LTS14116 studies were included in analysis. Here, 'number analyzed' = participants with available data for each specified category.

Skin biopsies were performed for the scoring of GL-3 accumulation/inclusions by light microscopy. Three independent pathologists scored GL-3 clearance by using an inclusion severity score of 0 (none/trace), 1 (mild), 2 (moderate), and 3 (severe), where higher score indicated more severe condition. A single score per participant per time point was derived by taking the score rated by a majority of the pathologists; if a majority score could not be derived, the median score was used. Data were summarized and reported in terms of number of participants with shift from baseline GL-3 score to Weeks 12, 26, 52, and 156 GL-3 score. Shift to lower score from baseline indicated less severe condition at that respective time point. Any shift category of Baseline score/Week score that was not observed (no participant had data in the category) was not reported. For this analysis, baseline was defined as initial ACT13739 study baseline.

Population: Analysis was performed on full analysis set: all participants who received at least 1 dose of IMP during the ACT13739 study.
