AE, adverse event; ALT, alanine aminotransferase; AST, aspartate aminotransferase; CNS, central nervous system; ECOG PS, Eastern Cooperative Oncology Group performance status; QTcF, QT interval corrected by Fridericia's formula; VM, visceral metastases.

Numbers (n) represent counts of patients. A patient with multiple severity grades for an AE was only counted under the maximum grade.
