Bemalenograstim Alfa for the Prevention in Patients With Colorectal Cancer/Pancreatic Cancer

This multi-cohort, open-label, multicenter exploratory clinical study enrolled 89 patients with colorectal cancer and pancreatic cancer who were scheduled to receive at least 2 courses of a two-week chemotherapy regimen. The study was divided into two cohorts: Cohort 1 was colorectal cancer or pancreatic cancer patients receiving FOLFOXIRI or mFOLFIRINOX in combination with or without targeted drugs, and cohort 2 was colorectal cancer patients receiving FOLFIRI in combination with or without targeted drugs. Patients meeting the inclusion criteria received Bemalenograstim alfa injection (20mg/ time, subcutaneous injection) 24-48h after each course of chemotherapy, and Bemalenograstim alfa injection was used until the change of chemotherapy regimen or the fourth course of chemotherapy, whichever occurred first. After the subjects completed 2 courses of treatment, the follow-up treatment was carried out according to the diagnosis and treatment routine. Investigators need to ensure that the first course of chemotherapy is at the recommended dose; For the second to fourth course of treatment, delayed dosing or dose adjustment due to toxicity is allowed, and the chemotherapy dose is allowed to be adjusted by ±10%.
