Title: Pegfilgrastim: evidence in support of its use with cytotoxic chemotherapy. Author: Ng R, Green MD. Journal: Expert Rev Anticancer Ther; 2005 Aug; 5(4):585-90. PubMed ID: 16111460. Abstract: The advent of granulocyte colony-stimulating factor, in particular filgrastim, in clinical use more than 10 years ago made a significant impact on the management of neutropenia and its complications. More recently, the application of pegylation technology has created a second-generation molecule, pegfilgrastim, with significantly altered pharmacokinetic properties. This has allowed for a once per chemotherapy cycle dosing in contrast to the requirement of daily subcutaneous administration for filgrastim. Several randomized trials in nonmyeloid malignancies have proven that a fixed dose of pegfilgrastim 6 mg is at least equivalent to daily filgrastim therapy. Emerging evidence also suggests that pegfilgrastim may be equally employed in the setting of chemotherapy for acute myeloid leukemia, dose-dense chemotherapy and peripheral stem cell mobilization. If confirmed in subsequent Phase III trials, it is likely that pegfilgrastim will eventually succeed filgrastim as the colony-stimulating factor of choice in clinical practice.[Abstract] [Full Text] [Related] [New Search]
