Time to disease flare was defined as the number of days from Day 1 (dosing) to the date of the first treated and Adjudication Committee (AC)-determined IgG4-RD flare within the 52-week RCP. The date of disease flare was determined by the initiation of any flare treatment, including new or increased glucocorticoid (GC) treatment, other immunotherapy, or an interventional procedure, as deemed necessary by the Investigator to address the flare. Kaplan-Meier (KM) method was used to estimate the median time to flare, and 95% confidence interval (CI).
MG-ADL score is an 8-item questionnaire that focuses on relevant symptoms and functional performance of activities of daily living over the previous 7 days. The MG-ADL score assesses disability secondary to ocular (2 items), bulbar (3 items), respiratory (1 item) and gross motor or limb (2 items) impairment related to effects from MG. Each response is graded 0 (normal) to 3 (most severe). The range of total MG-ADL scores is 0-24. A higher score represents more severe disease Outcome measure is reported for the overall population.
