5.3 Preclinical Safety Data

Genotoxicity. Varenicline had no genotoxic effects, with or without metabolic activation, based on the following assays: Ames bacterial mutation assay; mammalian CHO/HGPRT assay; and tests for cytogenic aberrations in vivo in rat bone marrow and in vitro in human lymphocytes.
Carcinogenicity. Carcinogenicity studies were performed in mice and rats at respective oral doses of varenicline up to 20 mg/kg/day and 15 mg/kg/day for 2 years, with respective systemic drug exposure (Cmax) up to 130 and 50 times the human plasma Cmax at the maximal recommended dose of 1 mg twice daily. There was no evidence of carcinogenicity in mice or female rats. Male rats showed increased incidences of hibernoma (a rare tumour of brown fat) at systemic exposures of 25 times the human Cmax (incidence 1/65 rats) and 50 times the human Cmax (incidence 2/65 rats); the no-effect exposure was 10 times the human Cmax. The clinical relevance of this finding has not been established.
