Palifermin
Generic Name: palifermin
Brand Names:
Kepivance
11 DESCRIPTION Kepivance (palifermin) is a truncated human KGF produced by recominant DNA technology in E coli . Kepivance is a water soluble, 140 amino acid protein with a molecular weight of 16.3 kilodaltons. It differs from endogenous human KGF in that the first 23 N terminal amino acids have been deleted to improve protein stability.

Uses
1 INDICATIONS AND USAGE Kepivance is a mucocutaneous epithelial human growth factor indicated to decrease the incidence and duration of severe oral mucositis in patients with hematologic malignancies receiving myelotoxic therapy in the setting of autologous hematopoietic stem cell support. Kepivance is indicated as supportive care for preparative regimens predicted to result in ≥ WHO Grade 3 mucositis in the majority of patients. ( 1.1 ) Limitations of Use The safety and efficacy of Kepivance have not been established in patients with non-hematologic malignancies ( 1.2 , 5.1 ) Kepivance was not effective in decreasing the incidence of severe mucositis in patients with hematologic malignancies receiving myelotoxic therapy in the setting of allogeneic hematopoietic stem cell support.
Dosage
2 DOSAGE AND ADMINISTRATION Administer as an intravenous bolus injection at a dose of 60 mcg/kg/day for 3 consecutive days before and 3 consecutive days after myelotoxic therapy for a total of 6 doses ( 2.1 ) Administer the first 3 doses prior to myelotoxic therapy with the third dose 24 to 48 hours before myelotoxic therapy ( 2.1 ) Administer the last 3 doses after myelotoxic therapy is complete with the first of these doses on the day of hematopoietic stem cell infusion after the infusion is completed, and at least 7 days after the most recent administration of Kepivance ( 2.1 ) 2.1 Recommended Dosage Regimen The recommended dose of Kepivance is 60 mcg/kg/day, administered as an intravenous bolus injection for 3 consecutive days before and 3 consecutive days after myelotoxic therapy, for...
Side Effects
6 ADVERSE REACTIONS Most common adverse reactions (incidence ≥20% and 5%≥placebo) are rash, fever, elevated serum amylase, pruritus, erythema, and edema ( 6 ) To report SUSPECTED ADVERSE REACTIONS, contact Swedish Orphan Biovitrum at 1-866-773-5274 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trial Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.
Interactions
7 DRUG INTERACTIONS In vitro and in vivo data showed that palifermin interacts with unfractionated as well as low molecular weight heparins with no noticeable effect on the pharmacodynamics of either drug. If heparin is used to maintain an intravenous line, rinse the line with saline prior to and after Kepivance administration [see Clinical Pharmacology ( 12.3 )] . Do not administer Kepivance within 24 hours before, during infusion of, or within 24 hours after administration of myelotoxic chemotherapy [see Dosage and Administration ( 2.1 ) and Clinical Studies ( 14 )]. In a clinical trial, administration of Kepivance within 24 hours of chemotherapy resulted in increased severity and duration of oral mucositis.
Warnings
5 WARNINGS AND PRECAUTIONS Potential for stimulation of tumor growth — Kepivance is not indicated for non-hematologic tumors. The effects of Kepivance on stimulation of keratinocyte growth factor (KGF) receptor-expressing, non-hematopoietic tumors in patients are not known ( 1 , 5.1 ) 5.1 Potential for Stimulation of Tumor Growth The safety and efficacy of Kepivance have not been established in patients with non-hematologic malignancies. The effects of Kepivance on stimulation of KGF receptor-expressing, non-hematopoietic tumors in patients are not known. Kepivance has been shown to enhance the growth of human epithelial tumor cell lines in vitro and to increase the rate of tumor cell line growth in a human carcinoma xenograft model [see Clinical Pharmacology ( 12.1 )]. 4 CONTRAINDICATIONS None None
Pregnancy
8.1 Pregnancy Risk Summary Based on findings in animal studies, Kepivance may cause fetal harm when administered to pregnant women. There are no data available on Kepivance use in pregnant women to inform a drug-associated risk of major birth defects and miscarriage or adverse maternal or fetal outcomes. In animal reproduction studies, intravenous administration of palifermin to pregnant rabbits and rats during the period of organogenesis resulted in embryo-fetal mortality and alterations to growth [see Data ] .
