Functional ability is assessed using the CHAQ-DI. The questionnaire consists of 30 questions referring to eight domains; dressing/grooming, arising, eating, walking, hygiene, reach, grip and activities. Each domain has at least two component questions and if applicable to the patient there are four possible responses (0 = without any difficulty, 1 = with some difficulty, 2 = with much difficulty, 3 = unable to do). The CHAQ-DI score is the sum of the domain scores divided by the number of domains that have a non-missing score. This overall score ranges from 0 (best) to 3 (worst).

Functional ability is assessed using the CHAQ-DI. The questionnaire consists of 30 questions referring to eight domains; dressing/grooming, arising, eating, walking, hygiene, reach, grip and activities. Each domain has at least two component questions and if applicable to the patient there are four possible responses (0 = without any difficulty, 1 = with some difficulty, 2 = with much difficulty, 3 = unable to do). The CHAQ-DI score is the sum of the domain scores divided by the number of domains that have a non-missing score. This overall score ranges from 0 (best) to 3 (worst).

Population: ITT3 population; n=number of participants contributing to the specific statistic

Participants who previously withdrew are excluded. Responders are participants who met all of the following criteria for inactive disease at the visit assessment day: i. Number of active joints = 0. ii. Absence of lymphadenopathy, hepatomegaly or splenomegaly in the nearest non-missing physical examination prior to or after the week assessment day. This could include results outside of the time window. iii. Absence of symptomatic serositis adverse event. iv.
