All 10 scores range from 5.79-70.42 . Higher scores indicated a better health state. Change from baseline in SF-36v2, 2 summary and 8 domains scores at week 52 is presented. Data is reported for 'on-treatment' observation period: from date of first dose of trial product (week 0) to last date on trial product with a visit window of +7 days (week 52).

The DQLCTQ-R questionnaire contains 57 items and measures and provide scores for the 8 domains (physical function, energy or fatigue, health distress, mental health, satisfaction, treatment satisfaction, treatment flexibility and frequency of symptoms). The 8 domain scores related to DQLCTQ-R are measured on a scale from 0-100. For all scores, higher values indicated better health status. Change from baseline in DQLCTQ-R 8 domain scores at week 52 is presented. Data is reported for 'on-treatment' observation period: from the date of first dose of trial product (week 0) to the last date on trial product with a visit window of +7 days (week 52).
