• History of other malignancies except: adequately treated non-melanoma skin cancer

Laborértékek

• Abnormal serum chemistry values, according to local laboratory normal values that indicate chronic liver or kidney dysfunction or that may be considered clinically significant (except for obesity related abnormal laboratory tests including blood glucose, Hgb A1c, liver transaminases, lipids for the obese, active group as stated above). Other abnormal lab values may also be exclusionary, at the discretion of the investigator
