*Median changes in creatine kinase from baseline to Wweek 12/ET were −1.0, 36.5, 52.0 and 8.5 U/L in the placebo, peficitinib 100 mg, peficitinib 150 mg and etanercept groups, respectively; changes to week 52 ET were 38.5, 75.0 and 10.0 U/L in the peficitinib 100 mg, peficitinib 150 mg and etanercept groups, respectively.
ALT, alanine aminotransferase; AST, aspartate aminotransferase; ET, early termination; HDL, high-density lipoprotein; LDL, low-density lipoprotein; SAF, safety analysis set.
