Mean (standard error [SE]) change from baseline in alanine aminotransferase (a), aspartate aminotransferase (b), hemoglobin (c), absolute lymphocyte count (d), absolute neutrophil count (e), creatinine (f), and creatine kinase (g), and mean (SE) percentage change from baseline in absolute CD16+56 (h), high-density lipoprotein-cholesterol (i), low-density lipoprotein-cholesterol (j), total cholesterol (k), and triglycerides (l), up to month 30. The dashed line represents the time between the baseline (month 0) and month 1 or month 3, as baseline refers to the baseline visit of the qualifying study for patients who enrolled within the 14-day window from the last visit of the qualifying study, or the baseline visit of this long-term extension (LTE) study for patients who enrolled outside of the 14-day window from the last visit of the qualifying study. Data are presented to month 30 because sample sizes were too small (N ≤ 50) for meaningful analysis beyond this point. N is the number of patients evaluable at each time point. Only evaluable patients at a visit of interest were included in the analysis and missing values were not imputed. aAverage dosing was based on an average total daily dose (ATDD) of tofacitinib: patients who received an ATDD < 15 mg/day were assigned to the average tofacitinib 5 mg twice daily (BID) group; patients who received an ATDD ≥ 15 mg/day were assigned to the average tofacitinib 10 mg BID group. bThe constant tofacitinib 5 mg BID group included all patients who started OPAL Balance on tofacitinib 5 mg BID and stayed on tofacitinib 5 mg BID (as per sponsor’s smoothing algorithm) until switching to tofacitinib 10 mg BID or discontinuing the study. Assessments (including exposure and adverse events) after dose switch to tofacitinib 10 mg BID were excluded from the analysis.
