Immunotoxic in a 4-week oral rat study, an expected immunosuppressive effect
“Delgocitinib was immunotoxic in a 4-week oral dose study in rats; however, this is an expected effect because of the pharmacological/immunosuppressive nature of delgocitinib.”
JAK-mediated immunosuppression, only partly assessable in animals; relevance of oral studies to topical use
“The relevance of oral studies for the topical formulation was initially questioned. The potential adverse effects of pharmacological JAK-inhibitory action on immune response in laboratory animals (housed in clean environment) could be assessed to a limited degree.”
