What was measured

Percentage of participants with TEAEs meeting DLT definition were reported. Toxicity was evaluated as per the NCI CTCAE, Version 5.0. The hematologic TEAEs of Grade ≥3 clearly unrelated to the underlying disease and occur during the first cycle that are considered DLTs: Grade ≥3 hemolysis; Grade 4 neutropenia for \>7 consecutive days; Grade 4 thrombocytopenia for \>14 consecutive days; Grade 3 thrombocytopenia with clinically significant bleeding; Any other Grade ≥4 hematologic toxicity except for Grade 4 lymphopenia. An incomplete recovery from treatment-related toxicity causing \>2-week delay in the next scheduled infusion before the initiation of Cycle 2 were considered a DLT. Percentages were rounded off to the nearest decimal.

Analysis population: The SAS included all enrolled participants who received at least 1 dose, even if incomplete, of TAK-573. Overall number of participants analyzed is the number of participants with data available for analysis.
