Decreased white blood cells and lymphocytes, reduced bone marrow cellularity (rat) and lymphocyte depletion in thymus and spleen
“Hematological changes were generally more pronounced in rats than dogs and included decreases in absolute white blood cells, reticulocytes, lymphocytes, monocytes, eosinophils, and basophils with microscopic correlates of decreased hematopoietic cellularity in bone marrow (rat), decreased lymphocytes in thymus (rat and dog), and spleen (dog).”

Prolonged retention in pigmented tissues of rats: up to 672 hours in uveal tract and 96 hours in pigmented skin
“Following IV administration of [14C] gedatolisib to pigmented male and female rats, radioactivity was highly concentrated and retained for a prolonged period for up to 672 hours and 96 hours in the uveal tract of the eye and pigmented skin, respectively.”
