Neutropenia research study

What is the primary objective of this study?

This study will assess the Efficacy and Safety of different doses of PEG-rhG-CSF and a single-dose of G-CSF in Preventing Chemotherapy-induced Neutropenia.

Who is eligible to participate?

Inclusion Criteria: - Age:18-70 years; - Comfirmed advanced tumor patients by histopathological with regarding initialtreatment or adjuvant, or neoadjuvant chemotherapy,suitable for chemotherapy with canboplatin combined with taxol or cyclophosphamide combined with pharmorubicin in the opinion of the investigator; - Performance status(EOCG)≤1; - Normal human peripheral blood are eligible for the chemotherapy, WBC≥3,500 per cubic millilit, ANC ≥ 1,500 per cubic milliliter, PLT ≥ 100,000 per cubic milliliter; - Normal ECG examination; - Without liver metastasis patients: the level of ALT、TBIL、AST were in the 2.5 times of upper normal limit; Liver metastasis patients: the level of ALT、TBIL、AST were in the 5 times of upper normal limit; - Renal function indices:the level of Cr、BUN were bothe in the 1.25 times of upper normal limit; - Life expectancy >3 months; - Signed informed consent.

Study Interventions

Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.

Drug:pegfilgrastim,30mcg/kgTwo doses SC injection of 30 mcg/kg at postchemotherapy 48hr and 120hr in cycle 2.

Drug:pegfilgrastim, 60mcg/kgSingle SC injection of the appropriate dose of drug ranging from 60 mcg/kg to 100 mcg/kg at postchemotherapy 48hr in cycle 2.

Drug:pegfilgrastim, 100mcg/kgSingle SC injection of the appropriate dose of drug ranging from 60 mcg/kg to 100 mcg/kg at postchemotherapy 48hr in cycle 2.

Drug:filgrastim, 5mcg/kgAt least 7 days SC injection of 5 mcg/kg at postchemotherapy 48hr in cycle 2.

Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.

pegfilgrastim,30mcg/kgOn the 3rd day and 6th day in Cycle 2, mean after 48h and 120h of chemotherapy, subjects will be received PEG-rhG-CSF(sc) in a fixed time(9:00±30 min), and the dosage is 30 mcg/kg.

pegfilgrastim, 60mcg/kgOn the 3rd day in Cycle 2, mean after 48h of chemotherapy, subjects will be assigned to PEG-rhG-CSF(sc, single) in a fixed time(9:00±30 min), and the dosage is 60 mcg/kg.

pegfilgrastim,100mcg/kgOn the 3rd day in Cycle 2, mean after 48h of chemotherapy, subjects will be assigned to PEG-rhG-CSF(sc, single) in a fixed time(9:00±30 min), and the dosage is 100 mcg/kg.

filgrastim,5mcg/kgOn the 3rd day in Cycle 2, mean after 48h of chemotherapy, subjects will be assigned to controlled group with rhG-CSF(sc, once a day) in a fixed time(9:00±30 min), and the dosage is 5mcg/kg, rhG-CSF must be injected for a continous 14 days, or twice observed the results for ANC from the nadir to counts≥5.0×10^9/L, but at least 7 days.
