Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Kepivance (palifermin) is a recombinant human keratinocyte growth factor (KGF) that binds to the KGF receptor, a splice variant of fibroblast growth factor receptor 2 (FGFR2b), stimulating proliferation, differentiation, and migration of epithelial cells, including those in the gastrointestinal tract.
Tetracycline antibiotic that inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing aminoacyl-t RNA from binding to the A site.
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 periodontal disease (adjunct to scaling and root planing),Topical treatment of infected wounds and skin ulcers
60 mcg/kg/day intravenously for 3 consecutive days before and 3 consecutive days after myelotoxic therapy.
Topical application of tetracycline hydrochloride 10 mg/g periodontal fiber. Inserted into periodontal pocket and left in place for 10 days.
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.
Not applicable due to local degradation; systemic half-life is negligible as tetracycline hydrochloride is not absorbed.
Metabolized via proteolytic degradation; no specific CYP450 involvement.
Not significantly metabolized; primarily excreted unchanged in urine and feces.
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 eliminated by phagocytic degradation at the application site; minimal systemic absorption, negligible renal or biliary excretion.
Approximately 95% bound to plasma proteins, primarily albumin.
Not applicable (no systemic absorption); if systemically present, tetracycline is 50-60% bound to plasma proteins.
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.
Not applicable due to lack of systemic absorption; if systemic, tetracycline Vd is 1.3-1.6 L/kg.
Subcutaneous administration: Absolute bioavailability is approximately 90% compared to intravenous administration. Not available orally; only given subcutaneously.
Negligible systemic bioavailability (<0.1%) when applied topically; not administered orally or intravenously for periodontal use.
No dose adjustment is recommended for renal impairment, but monitor serum creatinine.
Not systemically absorbed; no renal adjustment required.
No specific dose adjustment for Child-Pugh class A or B; use caution in severe impairment.
Not systemically absorbed; no hepatic adjustment required.
Safety and efficacy not established; no recommended pediatric dose.
Safety and efficacy not established in pediatric patients.
No specific dose adjustment, but consider age-related renal and hepatic function decline.
No specific dose adjustment; use standard adult dosing with caution for age-related comorbidities.
None.
None
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.
Photosensitivity,Superinfection with resistant organisms,Use in renal impairment may require dose adjustment,Not recommended in children under 8 years due to permanent tooth discoloration
Hypersensitivity to palifermin or any excipients.,Concurrent use within 24 hours of myelotoxic chemotherapy.
Hypersensitivity to tetracyclines,Severe renal impairment
No specific food interactions have been reported for KEPIVANCE. Maintain adequate nutrition and hydration as recommended by your healthcare provider.
No direct food interactions. Avoid eating on the treated side to prevent dislodgement of the fiber. Maintain soft diet to minimize trauma. Avoid alcohol-based mouthwashes.
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.
FDA Pregnancy Category C. No adequate studies in pregnant women. In animal studies, tetracycline hydrochloride (active component) caused fetal toxicity (skeletal malformations, reduced fetal weight) at doses 1-2 times the human dose. First trimester: potential for teratogenicity (neural tube defects, cardiovascular anomalies). Second and third trimesters: risk of permanent tooth discoloration (yellow-gray-brown) and enamel hypoplasia in the fetus; also potential for inhibition of fetal bone growth and maternal hepatotoxicity. Use only if potential benefit outweighs 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.
Tetracycline is excreted in human milk (M/P ratio approximately 0.6-1.5). Due to potential for serious adverse reactions (tooth discoloration, bone growth inhibition, photosensitivity) in nursing infants, a decision should be made to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother. Avoid prolonged use during breastfeeding.
No pharmacokinetic data in pregnancy. No dose adjustment recommendations are provided for pregnancy; use only if clearly needed.
No specific dose adjustments for ACTISITE (tetracycline periodontal fiber). Systemic absorption minimal (peak serum concentrations <0.1 mcg/m L). Pregnancy may alter pharmacokinetics of tetracycline (increased volume of distribution, decreased protein binding), but due to local administration, systemic effects are negligible. No dosage adjustment required for the fiber formulation; however, avoid systemic tetracycline use during pregnancy when possible.
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.
ACTISITE (tetracycline hydrochloride) periodontal fiber is a controlled-release local antibiotic for adjunctive treatment of chronic periodontitis. Insert fiber into periodontal pocket to deliver drug over 10 days. Ensure pocket depth is ≥5mm. Do not use with metallic or synthetic fibers. Fiber must be secured with cyanoacrylate adhesive. Monitor for foreign body sensation, pain, or infection. Removal at 10 days is mandatory to avoid excessive tissue reaction. Not for acute abscesses.
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.
Do not brush or floss the treated area while the fiber is in place.,Avoid chewing hard or sticky foods on the treated side.,You may feel a mild foreign body sensation; report severe pain or swelling.,The fiber must be removed after 10 days; do not leave it longer.,Complete the full course of prescribed oral hygiene and antibiotics if given.
