Rheumatol Ther. 2019

Peficitinib (PEF) 100 mg QD demonstrated a stable safety profile and sustained effectiveness in patients with moderate-to-severe RA in a two-year extension of two global phase IIb studies. Patients enrolled in the LTE had completed one of two 12-week phase IIb PEF trials, one with MTX and one without. The primary objective of the LTE was to assess treatment-emergent adverse events and clinical laboratory evaluations for 105 weeks. As a secondary objective, an additional 2-years of effectivenes...

Peficitinib in combination with MTX was well tolerated with a safety profile that was consistent with previous studies. A high placebo response rate was seen in both Latin and North America, when patient data were stratified. This high placebo rate is problematic for the accurate interpretation of pefic...
