简要总结
This is a phase 3, randomized, double-blind, placebo-controlled multi-center study evaluating the efficacy of pegfilgrastim to reduce the incidence of febrile neutropenia (FN) in patients with newly diagnosed, locally-advanced or metastatic colorectal cancer receiving first-line treatment with bevacizumab and either 5-fluorouracil, Oxaliplatin, Leucovorin (FOLFOX) or 5-fluorouracil, Irinotecan, Leucovorin (FOLFIRI).
This study will also investigate the effect of adding pegfilgrastim to bevacizumab and either FOLFOX or FOLFIRI by evaluating overall survival, progression-free survival, and overall response rate in each arm at regular intervals over a maximum of 60 months follow-up.

Patients may not have received prior radiotherapy to greater than 25% of bone marrow. Radiation must have concluded ≥ 4 weeks prior to enrollment. Prior radio-sensitizing chemoradiation will be allowed as long as it was concluded ≥ 4 weeks prior to enrollment.

时间窗: Approximately 2 months duration (Daily for 4 cycles of treatment; 2 weeks per cycle)
Grade 3/4 febrile neutropenia (FN) is defined as: • A temperature ≥ 38.0°C (≥ 100.4°F) and absolute neutrophil count (ANC) \< 1.0 × 10\^9/L, where ANC was measured the same day or within ± 1 calendar day of a temperature ≥ 38.0°C (≥ 100.4°F), or • An ANC \< 1.0 × 10\^9/L in combination with: - documented sepsis or infection, OR - neutropenia-related hospitalization where ANC was measured the same day or within ± 1 calendar day. Participants monitored their oral temperatures and maintained diaries to record their temperature twice per day: once in the morning and once in the evening, as well as whenever they suspect they had fever throughout the first 4 cycles of chemotherapy treatment.
