Recombinant human platelet-derived growth factor (rh PDGF-BB) that promotes chemotaxis and proliferation of fibroblasts, smooth muscle cells, and other cells involved in wound healing, and stimulates granulation tissue formation.
FDA-approved: To decrease the incidence and duration of severe oral mucositis in patients with hematologic malignancies receiving myelotoxic therapy requiring hematopoietic stem cell support.,Off-label: Prevention of oral mucositis in other cancers; management of acute radiation-induced mucositis.
Treatment of lower extremity diabetic neuropathic ulcers that extend into the subcutaneous tissue or beyond and have adequate blood supply.,Off-label: pressure ulcers, venous stasis ulcers, other chronic wounds.
60 mcg/kg/day intravenously for 3 consecutive days before and 3 consecutive days after myelotoxic therapy.
Apply topically once daily, a thin layer to the full area of the ulcer, using a measured amount of gel based on ulcer length and width in centimeters: (length × width × 0.5) grams.
Terminal elimination half-life is approximately 4.5 hours in healthy adults. In patients with renal impairment (Cr Cl <30 m L/min), half-life is prolonged up to 2-fold, requiring dose adjustment. The half-life supports once-daily dosing for 3 consecutive days before chemotherapy.
Terminal half-life ~30-60 minutes after topical application; prolonged in renal impairment (up to 2-3 hours). Clinical context: Short systemic exposure limits off-target effects.
Metabolized via proteolytic degradation; no specific CYP450 involvement.
Metabolized locally; no systemic metabolism expected due to topical administration and minimal absorption. If absorbed, degraded by proteolytic enzymes at the wound site.
Primarily renal; approximately 90% of the dose is excreted unchanged in urine within 24 hours via glomerular filtration and tubular secretion. Minimal biliary/fecal elimination (<5%).
Primarily renal; minimal biliary/fecal. Becaplermin is cleared renally (>90% as metabolites) with <2% excreted unchanged. Fecal elimination accounts for <10%.
Approximately 95% bound to plasma proteins, primarily albumin.
~25% bound to plasma proteins (primarily albumin).
Volume of distribution at steady state (Vd_ss) is approximately 0.2 L/kg, indicating limited extravascular distribution, consistent with a large protein-bound molecule. Does not distribute extensively into tissues.
Vd ~12 L (~0.17 L/kg assuming 70 kg), indicating limited extravascular distribution due to molecular size.
Subcutaneous administration: Absolute bioavailability is approximately 90% compared to intravenous administration. Not available orally; only given subcutaneously.
Topical: Negligible systemic bioavailability (<1% of applied dose absorbed; increased with large wounds or impaired skin barrier).
No dose adjustment is recommended for renal impairment, but monitor serum creatinine.
No dose adjustment required for renal impairment.
No specific dose adjustment for Child-Pugh class A or B; use caution in severe impairment.
No dose adjustment required for hepatic impairment.

No specific dose adjustment recommended; use with caution due to potential comorbidities and polypharmacy.
None.
Increased risk of mortality secondary to malignancy in patients treated with 3 or more tubes of REGRANEX (becaplermin) Gel. A postmarketing study showed increased mortality from cancer in patients who used three or more tubes of REGRANEX compared to control patients. REGRANEX should only be used when the benefits can be expected to outweigh the risks. REGRANEX is not recommended in patients with known malignancy.
Potential for stimulation of epithelial tumor growth (use caution in patients with non-hematologic malignancies).,Risk of allergic reactions including anaphylaxis.,May cause oral mucosal thickening and dental abnormalities.,Avoid use within 24 hours before or after myelotoxic chemotherapy.
Application to wounds with active malignancy may promote tumor growth. Application to wounds with infection or necrotic tissue should be discontinued until infection is controlled or necrotic tissue debrided. Potential for immunogenicity.
Hypersensitivity to palifermin or any excipients.,Concurrent use within 24 hours of myelotoxic chemotherapy.
Known hypersensitivity to becaplermin or any product component. Application to wounds with known neoplasms or active malignancy. Use on wounds closed by primary intention.
No specific food interactions have been reported for KEPIVANCE. Maintain adequate nutrition and hydration as recommended by your healthcare provider.
No known food interactions. Regranex is applied topically and has minimal systemic absorption.
KEPIVANCE (palifermin) is a recombinant human keratinocyte growth factor. No adequate and well-controlled studies in pregnant women. In animal reproduction studies, palifermin was not teratogenic in rats or rabbits at doses up to 100 mg/kg/day (IV), which produced exposures approximately 40 and 80 times the human exposure at the recommended clinical dose of 60 mcg/kg/day, based on AUC. However, there are no human data. Risk in first trimester: unknown; second and third trimesters: unknown.
No adequate and well-controlled studies in pregnant women. Animal studies at doses 25-100 times human exposure show no fetal harm. Risk cannot be ruled out; use only if potential benefit justifies potential risk.
It is not known whether palifermin is excreted in human milk. No data on M/P ratio. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from palifermin, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.
It is not known whether becaplermin is excreted in human milk. M/P ratio unknown. Use caution; consider developmental and health benefits of breastfeeding along with mother's clinical need for REGRANEX.
No pharmacokinetic data in pregnancy. No dose adjustment recommendations are provided for pregnancy; use only if clearly needed.
No pharmacokinetic data in pregnancy. Dosage adjustments are not recommended based on current knowledge; use same dosing as non-pregnant adults.
KEPIVANCE (palifermin) is a recombinant human keratinocyte growth factor used to decrease the incidence and duration of severe oral mucositis in patients with hematologic malignancies undergoing myelotoxic therapy requiring hematopoietic stem cell support. Administer as a 3-day course of 60 mcg/kg/day IV bolus for 3 consecutive days before and 3 consecutive days after myelotoxic therapy. Must be given at least 24 hours before and after chemotherapy; do not administer within 24 hours of chemotherapy due to risk of enhanced cytotoxicity. Monitor for skin reactions, oral/perioral edema, and taste alteration. Contraindicated in patients with known hypersensitivity to E. coli-derived proteins.
Regranex (becaplermin) is a recombinant platelet-derived growth factor (PDGF) gel indicated for diabetic neuropathic ulcers extending into subcutaneous tissue or deeper. Ensure ulcer is free of infection, necrotic tissue, and has adequate blood supply before initiating therapy. Apply a thin layer once daily, and recalibrate gel amount based on ulcer dimensions (length x width x 0.5 for cm to grams). Do not use on wounds with exposed bone, tendon, or joint. Monitor for increased risk of malignancy; contraindicated in patients with active malignancies. The gel is for single-patient use only; discard tube 30 days after opening.
KEPIVANCE reduces the severity and duration of mouth sores caused by high-dose chemotherapy.,It is given as a short intravenous infusion once daily for 3 days before and 3 days after your chemotherapy.,You may experience swelling of the mouth, tongue, or lips; skin rash; or changes in taste. Report these to your healthcare team.,Do not receive KEPIVANCE within 24 hours before or after chemotherapy.,Inform your doctor if you have any allergies, especially to E. coli-derived products.
