| Duration of severe neutropenia in cycle 1 | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Secondary efficacy endpoints: 1.1. Incidence of observed febrile neutropenia (FN) (observed FN defined as body temperature of >38.5°C for more than 1 hour, measured axillary with a calibrated standard device, and ANC <0.5 x 10^9/L, both measured on the same day) and of protocol defined FN (intake of systemic antibiotics) by cycle and across all cycles 1.2. Duration of severe neutropenia in cycles 2 to 4 1.3. Depth of ANC nadir in cycles 1 to 4 1.4. Times to ANC recovery in cycles 1 to 4 1.5. Mortality 2. Safety endpoints, determined at the beginning and at the end of each chemotherapy cycle until day 85, antibody determination until day 180: 2.1. Adverse events (AEs) 2.3. Safety laboratory assessment 2.4. Physical examination 2.5. Injection site reactions 2.6. Vital signs 2.7. Eastern Cooperative Oncology Group (ECOG) performance 2.8. Immunogenicity (development of antibodies against study drug) Other: 3. Pharmacokinetics in a subset of patients | — |
