| Number of Participants With Treatment-Emergent Adverse Events by Severity | The severity of the AEs are categorized into Grades 1 to 5: Grade 1: Mild- asymptomatic or mild symptoms, Grade 2: Moderate- minimal; local or noninvasive intervention indicated, Grade 3: Severe or medically significant but not immediately life-threatening, Grade 4: Life-threatening consequences, and Grade 5: Death related to AE. An AE was defined as any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. TEAE is any new event that starts after the first administration of study treatment and <=30 days after treatment discontinuation or that worsened during that study period. | From the first study treatment infusion in Cycle 1 (each cycle of 21 days) until the safety follow-up in expansion part (approximately 44 months) |
