Number of participants with DLTs. A DLT is defined as an adverse event or abnormal laboratory value of Common Terminology Criteria for Adverse Events (CTCAE) grade 3 or higher, unless clearly and inconvertibly assessed as due to disease progression, inter-current illness/injury, concomitant medications, or extraneous causes, that occurs within the first 28 days of treatment in the Phase 1 part. Other clinically significant toxicities may be considered to be DLTs, even if not CTCAE grade 3 or higher.
Number of participants with AEs and SAEs, including changes in vital signs, electrocardiograms (ECGs) and laboratory values qualifying and reported as AEs.
Number of participants with dose adjustments (reductions, interruption, or permanent discontinuation) as a measure of tolerability.
The dose intensity of each study drug is computed as the ratio of actual cumulative dose received and actual duration of exposure.
