- Have an established diagnosis of Type 1 diabetes mellitus or Type 2 diabetes mellitus with hemoglobin A1c (HbA1c) ≥8%, fasting blood glucose (FBG) ≥140 milligrams per deciliter (mg/dL), or requiring insulin.Have inflammatory or metaplastic breast cancer.History of leptomeningeal disease or carcinomatous meningitis.Have known and untreated or active central nervous system (CNS) metastases.Exception: Asymptomatic brain or spinal metastases if treated by surgery, surgery plus radiotherapy, or radiotherapy alone with no evidence of radiographic progression or hemorrhage within at least 28 days before randomization and no requirement for anticonvulsants or systemic corticosteroids for at least 28 days before randomization.Have received treatment with any local or systemic antineoplastic therapy or investigational anticancer agent within 14 days or 4 half-lives, whichever is longer, prior to randomization up to a maximum washout period of 28 days.Have a diagnosis of immunodeficiency or is receiving chronic systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to randomization.
