I 2- års carcinogenicitets- undersøgelser på rotter (≥1 mg/ kg/ dag; 7 gange den systemiske eksponering efter en human dosis på 0, 5 mg/ dag, baseret på plasma- AUC) sås en øget forekomst af renale tubulære adenomer og carcinomer hos hanner og granulosacelletumorer i ovarierne hos hunner.
In two-year carcinogenicity studies conducted in rats (≥ 1 mg/ kg/ day; 7 times systemic exposure following a human dose of 0.5 mg/ day based on plasma AUC) an increased incidence of renal tubular adenoma and carcinoma in males and granulosa cell tumours of the ovary in females was noted.
