In a 12-week phase 3 trial, tofacitinib,10 mg twice a day, was non-inferior to etanercept, 50 mg twice a week. Tofacitinib, 5 mg twice a day, was inferior to etanercept.

Tofacitinib, 10 mg twice a day was non-inferior to etanercept 50 mg twice a week. Tofacitinib 5 mg twice a day was inferior to etanercept.
Adverseeffects were similar, but a commentary says, “We do not know the real risk of any drug until it has been used in thousands of patients for many years.”
However, the risks of psoriasis drugs must be weighed against the comorbidities of psoriasis itself.
This Pfizer-sponsored phase 3, placebo-controlled, 12-week non-inferiority trial compared 1,106 patients with moderate to severe psoriasis on two doses of tofacitinib with etanercept and placebo. End points were Psoriasis Area and Severity Index (PASI) score reduction of at least 75% by week 12 (PASI75), and percent of patients achieving a Physician’s Global Assessment (PGA) of “clear” or “almost clear.”
