Uses for Kepivance
Chemotherapy-induced Oral Mucositis
Reduction in the incidence and duration of severe oral mucositis in patients with hematologic malignancies receiving myelotoxic chemotherapy followed by hematopoietic stem cell transplantation.1 2 5 6
Kepivance Dosage and Administration
Administer by direct IV injection.1
Do not administer during or within 24 hours before or after infusion of myelotoxic chemotherapy.1 (See Potentiation of Oral Mucositis under Cautions.)
Reconstitute with sterile water for injection according to manufacturer’s directions to prepare a solution containing 5 mg/mL.1 Swirl vial gently during dissolution; do not shake or vigorously agitate.1 Dissolution should take <3 minutes.1 Do not filter reconstituted solutions during preparation or administration.1
Chemotherapy-induced Oral Mucositis
Initially, 60 mcg/kg daily, administered by direct IV injection on 3 consecutive days before and 3 consecutive days after myelotoxic chemotherapy (total of 6 doses).1
Administer the first 3 doses (doses 1–3) on the 3 consecutive days prior to myelotoxic chemotherapy, with the third dose administered 24–48 hours before such chemotherapy.1 Administer the last 3 doses (doses 4–6) on the 3 consecutive days after myelotoxic chemotherapy, with the first of the 3 doses (i.e., dose 4) administered after, but on the same day as, hematopoietic stem cell infusion and at least 4 days after the previous dose (dose 3) of the drug.1
No special population recommendations at this time.1
Cautions for Kepivance
Known hypersensitivity to Escherichia coli-derived proteins, palifermin, or any ingredient in the formulation.1
Potentiation of Oral Mucositis
Increased severity and duration of oral mucositis observed in patients receiving palifermin within 24 hours of chemotherapy administration, presumably because of increased sensitivity of rapidly dividing epithelial cells to chemotherapy after palifermin treatment.1 Do not administer during or within 24 hours before or after infusion of myelotoxic chemotherapy.1
Stimulation of Tumor Growth
Safety and efficacy not established in patients with nonhematological malignancies.1 Potential for stimulation of growth of nonhematologic tumors that express the keratinocyte growth factor receptor not established.1 Has been reported to stimulate growth of human epithelial tumor cell lines in vitro at concentrations >15-fold higher than average therapeutic concentrations in humans.1
Safety and efficacy not established.1
Experience in patients ≥65 years of age insufficient to determine whether they respond differently than younger adults.1
Common Adverse Effects
Arthralgia,1 dysesthesia (hyperesthesia, hypoesthesia, paresthesia),1 edema,1 3 5 elevated serum amylase1 5 or lipase concentrations,1 5 erythema,1 3 5 fever,1 3 mouth or tongue thickness or discoloration,1 pain,1 pruritus,1 3 rash,1 3 5 taste alteration.1 3
Interactions for Kepivance
No formal drug interaction studies performed.1
Severity of oral mucositis associated with myelotoxic chemotherapy may be enhanced if palifermin is administered within 24 hours of myelotoxic chemotherapy.1 (See Potentiation of Oral Mucositis under Cautions.)
Dose-dependent epithelial cell proliferation observed 48 hours after single IV doses of 120–250 mcg/kg in healthy individuals.1
Mean 4.5 hours (range 3.3–5.7 hours).1
Following a single dose of 60 mcg/kg, total body clearance averaged twofold to fourfold higher and volume of distribution at steady state averaged twofold higher in cancer patients compared with healthy individuals.1
Powder for Injection
Lyophilized powder and reconstituted solutions: 2–8°C; protect from light.1
Reconstituted solutions (5 mg/mL in sterile water for injection): Should be used immediately, but may be stored for ≤24 hours at 2–8°C.1
For information on systemic interactions resulting from concomitant use, see Interactions.
Binds to heparin in vitro; if administered via an IV line maintained with heparin, flush line with 0.9% sodium chloride solution prior to and following palifermin administration.1
Shown to enhance the growth of human epithelial tumor cell lines in vitro and in animal studies.1 (See Stimulation of Tumor Growth under Cautions.)
Advice to Patients
Importance of advising patients about potential adverse mucocutaneous effects (e.g., rash, erythema, edema, pruritus, perioral dysesthesia, tongue discoloration, tongue thickening, taste alteration) and of informing clinicians if these or other adverse effects occur during therapy.1
Importance of advising patients about in vitro and in vivo evidence of tumor growth stimulation by palifermin in nonhematopoietic tissues.1
Importance of women informing clinicians if they are or plan to become pregnant or plan to breast-feed.1
Importance of informing clinicians of existing or contemplated concomitant therapy, including prescription and OTC drugs, as well as concomitant illnesses.1
Importance of informing patients of other important precautionary information.1 (See Cautions.)
Excipients in commercially available drug preparations may have clinically important effects in some individuals; consult specific product labeling for details.
