Study Endpoints
Primary Endpoints
Number of Participants With First Cycle Dose Limiting Toxicities (DLTs)
Baseline up to Cycle 1 Day 21 (C1.D21)

At least possibly attributable to study treatment (Tx): Grade (Gr) 4 neutropenia (absolute neutrophil count \[ANC\] \<500 cells/mm\^3) for \>7 days or Gr 3 febrile neutropenia (ANC \<1000/mm\^3, fever ≥38 degrees Celsius; Gr 4 thrombocytopenia (platelets \<25,000 cells/mm\^3); Gr ≥3 non-hematologic toxicity despite adequate medical intervention; Gr ≥3 confirmed prolonged QTc interval (\>500 milliseconds \[msec\]); confirmed cardiac troponin I ≥99 percentile of reference range; Tx related toxicities with failure to receive ≥18 days Tx in 21-day cycle or inability to resume current dose level ≤14 days.

Percentage of Participants With Tumor Metabolic Response (Reduction of ≥15%) in Positron Emission Tomography With F-18-fluorodeoxyglucose (FDG-PET)
Baseline, C1.D14

Metabolic response demonstrated in any tumor reduction of ≥15% in tumor FDG standardized uptake value (SUV) in Cycle 1; based on the recommendations of the European Organization for Research and Treatment of Cancer (EORTC) PET Study Group. Participant must have had a baseline PET with at least 1 tumor lesion demonstrating an FDG SUV of ≥5.
