Lymphocyte decreases and lymphoid organ atrophy attributed to weak glucocorticoid activity
“The changes observed in the white blood cells population, in the adrenals and in the lymphoid organs (spleen, thymus) were probably related to the weak glucocorticoid activity of the clascoterone.”
Significant accumulation on repeat dosing (AUC ratio 6.38-20.3 in 9-month dermal minipig study)
“After repeated administrations in some toxicity studies in rats and in minipigs, a significant accumulation was observed (e.g. in 9 months dermal in minipigs, the ratio of AUC ranged from 6.38 to 20.3), varying in extent depending on the doses and treatment duration.”
Adrenal cortical atrophy, not fully reversible in males
“At the MD and HD, adrenal gland weight decreased in both sexes, corresponding with the microscopic finding of cortical atrophy; these findings were fully reversible in females but not males”
