Parts 1 and 2 Combined: Number of Participants With Any Treatment-emergent Adverse Event (TEAE) |
Adverse events were defined as the appearance of (or worsening of any pre-existing) undesirable sign(s), symptom(s), or medical condition(s) that occurred after a participant provided informed consent. Abnormal laboratory values or test results that occurred after informed consent constituted AEs only if they induced clinical signs or symptoms, were considered clinically meaningful, required therapy (e.g., hematologic abnormality that required transfusion), or required changes in the study drug(s). TEAEs were defined as adverse events either reported for the first time or the worsening of pre-existing events after the first dose of study drug and within 30 days of the last dose of study drug. |
