- timeFrame
- (Timeframe: up to 28 days)
- description
- A DLT is defined as an event with toxicity including the type, severity, time of onset, time of resolution, and the probable association with study treatment that are not due to pre-existing conditions as defined by the Common Terminology Criteria for Adverse Events Version 5.0 (CTCAE 5.0). The number of participants who experience a DLT will be reported.
