Intravenous bolus of 0.1 mg/kg given over 1 minute, followed by continuous intravenous infusion of 0.6 mg/kg/min for 30 minutes. Alternatively, a single intravenous bolus dose of 0.3 mg/kg.
1 drop in the affected eye(s) twice daily, approximately 6 hours apart.
Terminal elimination half-life is approximately 8-10 hours in adults; clinically, steady-state is achieved within 2-3 days.
Terminal elimination half-life of Cenegermin is approximately 12 hours following topical ocular administration, supporting once-daily dosing
Primarily metabolized by proteolysis into smaller peptides and amino acids; not significantly metabolized by CYP enzymes.
Becaplermin is a protein that is expected to be degraded into small peptides and amino acids via general protein catabolism; specific hepatic metabolism is not a significant pathway.
Renal: ~95% of absorbed dose as unchanged drug and metabolites; fecal: <5%.
Primarily renal elimination of the active metabolite (Cenegermin) as small peptides and amino acids; unchanged drug excretion is negligible
Approximately 90% bound to insulin-like growth factor binding proteins (IGFBPs).
Cenegermin binding to plasma proteins is minimal (<10%) due to its small protein nature
Vd ~0.3-0.5 L/kg, indicating distribution primarily into extracellular fluid.
Vd not determined for topical ocular route; systemic exposure is low, with Vd estimated less than 0.1 L/kg based on limited systemic absorption
Subcutaneous: 80-100% (high bioavailability).
Topical ocular: Systemic bioavailability is negligible (<1%) due to low corneal penetration and extensive proteolysis at the ocular surface

Increased risk of neoplasms; do not use in patients with active or suspected malignancy. Monitor for progression of pre-existing nevi.
OXERVATE has been associated with an increased risk of mortality from secondary malignancies in patients who have had a malignant neoplasm. The drug should not be used in patients with active malignancy.
Risk of malignancy (including intracranial tumors),Lymphoproliferative disorders,Intracranial hypertension (pseudotumor cerebri),Slipped capital femoral epiphysis,Progression of scoliosis,Pancreatitis,Hypoglycemia (especially with fasting or missed meals),Fluid retention (edema, pericardial effusion),Hypersensitivity reactions including anaphylaxis,Thymic hypertrophy
Increased risk of malignancy in patients with a history of malignancy; application to ulcers with malignant cells may promote tumor growth; use only on clean, non-infected ulcers; monitor for signs of infection; avoid application to wounds with exposed bone, tendon, or joint capsule.
Active or suspected malignancy (including intracranial tumors),Closed epiphyses (skeletal maturity),Acute critical illness (due to increased mortality with ICU use),Hypersensitivity to mecasermin or any component
Known hypersensitivity to becaplermin or any product component; active neoplasm at the application site; patients with a history of malignancy (relative contraindication based on black box warning).
Must be administered within 20 minutes of a meal or snack containing carbohydrates to reduce risk of hypoglycemia. Avoid fasting or skipping meals. Grapefruit/grapefruit juice may alter CYP3A4 metabolism; avoid concurrent use. Alcohol can increase hypoglycemia risk; limit or avoid.
None known; no significant food interactions reported.
INCRELEX (mecasermin) is an IGF-1 analog. In animal studies, there is no evidence of teratogenicity; however, data in pregnant women are insufficient. First trimester: No known malformation risk. Second/third trimesters: Fetal overgrowth (macrosomia) may occur if maternal IGF-1 levels are elevated. Caution advised.
OXERVATE contains cenegermin, a recombinant human nerve growth factor. No adequate and well-controlled studies in pregnant women. Animal reproductive studies have not been conducted. Risk cannot be ruled out; use only if potential benefit justifies potential risk to fetus. First trimester: unknown risk; second and third trimesters: unknown risk.
Excretion into human milk unknown; molecular weight (7.5 k Da) suggests minimal transfer. M/P ratio not established. Caution recommended; alternative feeding may be considered until more data available.
No data on presence in human milk, effects on breastfed infant, or milk production. Caution advised; M/P ratio unknown.
No established dose adjustments. Physiologic changes in pregnancy (increased renal clearance, plasma volume) may reduce drug levels; however, safety and efficacy data are lacking. Use only if clearly needed with careful monitoring.
No pharmacokinetic studies in pregnancy; dose adjustments not established. Use standard dosing with caution.
INCRELEX (mecasermin) is recombinant human insulin-like growth factor-1 (IGF-1) used for growth failure in severe primary IGF-1 deficiency. Monitor blood glucose closely due to risk of hypoglycemia; administer within 20 minutes of a meal or snack. Do not use in patients with closed epiphyses, active malignancy, or history of malignancy. Can cause intracranial hypertension (pseudotumor cerebri); monitor for headache, visual disturbances. Injection site reactions common.
