Level of evidence: B

Baricitinib (2-4 mg/day) treatment alone or in combination with topical treatment appears to increase the proportion of adult patients with moderate-to-severe atopic dermatitis achieving EASI-75 response at week 16, when compared to placebo (2 mg: 18-43%, 4 mg: 21-48%, and placebo 6-23%).

In addition, baricitinib compared to placebo may increase the proportion of patients achieving EASI-90, with improvement in peak score on numerical rating scale (NRS) for pruritus.

The efficacy evidence is based on 3 RCTs with low risk of bias, applicability of the evidence is high.
