What was measured

The following toxicities graded for severity using National Cancer Institute (NCI) Common Terminology for Adverse Events (CTCAE), were considered a DLT if judged by the investigator to be possibly related to study investigational products: 1) Grade 4 nonhematologic toxicity (ie. not a laboratory finding). 2) Grade 4 hematologic toxicity lasting ≥ 7 days, except thrombocytopenia: 3) Grade 4 thrombocytopenia of any duration 4) Grade 3 thrombocytopenia associated with clinically significant bleeding 5) Any nonhematologic AE ≥ Grade 3 in severity, with some exceptions 6) Any Grade 3 or Grade 4 nonhematologic laboratory value that meets one of the study criteria 7) Febrile neutropenia Grade 3 or Grade 4 8) Prolonged delay (\>2 weeks) in initiating Cycle 2 due to treatment-related toxicity. 9) Any treatment-related toxicity that causes participant to discontinue treatment during Cycle 1. 10) Grade 5 toxicity 11) Any other clinically significant toxicity judged to be a DLT by investigator.

Analysis population: The DLT evaluable population included all participants who received at least 1 dose of study treatment and were either observed for safety for 21 days after the first dose of treatment or experienced a DLT prior to 21 days after the first dose of treatment.
