As such, it affects T-cells through inhibition of T-cell activities including their infiltration processes, and it shows direct anti-inflammatory manifestation in the mouse edema model. This was a 28 day study (plus one follow-up week) on patients with Atopic Dermatitis, and 36 patients were treated randomly, BID with either 0.5%, 1.0% or placebo.
