Критерии исключения

• Symptomatic primary Central Nervous System (CNS) cancer or metastases unless the symptoms are stable for at least 28 days prior to the first dose of the study drug and any symptoms have returned to baseline
• Evidence of abnormal cardiac function
• History of uncontrolled allergic reactions and/or known expected hypersensitivity to the study drugs used in the treatment arm to which the participant is to be enrolled into
• Any other known active malignancy except for treated cervical intraepithelial neoplasia, or non-melanoma skin cancer
• Any uncontrolled illness or significant uncontrolled condition(s) requiring systemic treatment
• Known Human Immunodeficiency Virus (HIV) infection
• Active hepatitis B or hepatitis C infection
• Pregnant or breast feeding
