Ramucirumab is a human Ig G1 monoclonal antibody that binds to vascular endothelial growth factor receptor 2 (VEGFR-2) and blocks the interaction between VEGFR-2 and its ligands, VEGF-A, VEGF-C, and VEGF-D, thereby inhibiting receptor activation and subsequent angiogenesis.
ELLENCE (epirubicin) is an anthracycline cytotoxic antibiotic. It intercalates between DNA base pairs, inhibits topoisomerase II activity, and generates free radicals, leading to DNA damage and cell death.

8 mg/kg intravenously every 2 weeks or 10 mg/kg intravenously every 2 weeks if used in combination with paclitaxel or FOLFIRI.
60-120 mg/m2 IV bolus or slow infusion on Day 1 every 21-28 days; or 20-30 mg/m2 IV daily for 3 days repeated every 28 days.
Terminal elimination half-life is approximately 14 days (range 11–17 days) at steady state, supporting a dosing interval of every 2 weeks.
Terminal elimination half-life is approximately 20-40 hours (mean ~30 hours). This supports a 3-week dosing interval to allow for recovery from myelosuppression.
Ramucirumab is a monoclonal antibody; metabolism is via catabolism into small peptides and amino acids (nonspecific proteolytic degradation). No major metabolic enzymes involved.
Primarily hepatic metabolism via aldoketoreductases and conjugation; also metabolized by glucuronidation and cytochrome P450 (CYP) enzymes, including CYP2B4 and CYP3A4.
Ramucirumab is eliminated primarily via proteolytic catabolism; no renal or biliary excretion occurs. Clearance is 0.014 L/h (0.022 L/h with high VEGF), with a mean terminal half-life of 14 days (range 11–17 days) at steady state.
Primarily hepatobiliary excretion: ~40-50% of dose excreted as unchanged drug and metabolites in bile and feces. Renal excretion accounts for <10% (mostly as metabolites).
Approximately 95% bound to serum proteins, primarily albumin and immunoglobulins.
Approximately 77% bound to plasma proteins, primarily albumin.
Volume of distribution at steady state is approximately 5.0–6.0 L, corresponding to 0.07–0.09 L/kg (assuming 70 kg body weight), indicating limited extravascular distribution primarily within plasma volume.
Mean volume of distribution is 13-34 L/kg (average ~21 L/kg), indicating extensive tissue distribution and binding.
Bioavailability is 100% as ramucirumab is administered only by intravenous infusion; no oral or other form is available.
IV only; oral bioavailability is negligible (<5%) due to extensive first-pass metabolism. Not administered orally.
No dose adjustment recommended for mild to moderate renal impairment (Cr Cl >=30 m L/min). Not studied in severe renal impairment or dialysis.
No specific GFR-based dose adjustments required; caution in severe renal impairment (Cr Cl <10 m L/min) with potential increased toxicity.
No dose adjustment recommended for mild hepatic impairment (Child-Pugh A). For moderate (Child-Pugh B) and severe (Child-Pugh C) hepatic impairment, no dosing information available; use with caution.
Child-Pugh A: reduce dose by 25%; Child-Pugh B: reduce dose by 50%; Child-Pugh C: contraindicated or use at 50% reduction with caution.
Safety and efficacy not established in pediatric patients.
75-100 mg/m2 IV on Day 1 of 21-day cycles or 20-30 mg/m2 IV daily for 3 days every 28 days.
No dose adjustment required based on age. Monitor for increased risk of adverse events such as hypertension, hemorrhage, and gastrointestinal perforations.
No specific dose adjustment; consider increased susceptibility to myelosuppression and cardiotoxicity; monitor left ventricular ejection fraction.
Hemorrhage: Severe or fatal hemorrhage, including gastrointestinal hemorrhage, hemoptysis, and intracranial hemorrhage, has occurred. Do not administer in patients with severe bleeding.
Myocardial toxicity, including potentially fatal congestive heart failure, especially with cumulative doses >900 mg/m²; secondary acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS); extravasation leading to severe tissue necrosis; severe myelosuppression.

No specific food interactions are documented. Avoid grapefruit juice if taking concomitant drugs metabolized by CYP3A4 (e.g., simvastatin) due to potential interaction, but no direct interaction with ramucirumab.
Avoid grapefruit and grapefruit juice during treatment as they may affect drug metabolism. No other specific food interactions known.
Cyramza (ramucirumab) is a VEGF receptor antagonist. Based on its mechanism of action and animal studies, it can cause fetal harm when administered to pregnant women. In animal reproduction studies, intravenous administration of ramucirumab to pregnant rabbits during organogenesis resulted in embryofetal mortality and reduced fetal weight at exposures less than the recommended human dose. There are no adequate and well-controlled studies in pregnant women. Cyramza is contraindicated in pregnancy. First trimester: High risk of teratogenicity; VEGF inhibition interferes with embryonic vascular development. Second and third trimesters: Risk of fetal growth restriction, oligohydramnios, and potential for fetal renal impairment due to anti-angiogenic effects. Avoid use during pregnancy.
Pregnancy Category D. First trimester: High risk of teratogenicity including cardiac anomalies, skeletal defects, and fetal demise. Second and third trimesters: Risk of fetal growth restriction, preterm birth, and neonatal myelosuppression. Avoid use unless absolutely necessary.
No human data available on the presence of ramucirumab in human milk, effects on the breastfed infant, or effects on milk production. Ramucirumab is a large protein molecule (Ig G1 monoclonal antibody) and is likely to be present in breast milk at low levels, especially in early postpartum period. However, because of the potential for serious adverse reactions in the breastfed infant, advise women not to breastfeed during treatment and for at least 2 months after the last dose. M/P ratio: Not determined.
Contraindicated due to potential transfer into breast milk (M/P ratio not available). Theoretical risk of severe adverse effects in infants including bone marrow suppression and cardiotoxicity. Discontinue nursing or drug.
Cyramza is contraindicated in pregnancy; no dosing adjustments are recommended as use should be avoided. If used inadvertently, no specific pharmacokinetic data in pregnancy are available; however, physiological changes (e.g., increased plasma volume, altered renal function) may affect drug clearance, but no dose adjustment guidelines exist. The risk of fetal harm outweighs any potential benefit, and treatment should be discontinued immediately if pregnancy occurs.
No established dose adjustments; avoid use if possible. Pharmacokinetic changes include increased volume of distribution and clearance, but insufficient data to recommend dose modification. Use reduced doses if unavoidable, guided by toxicity monitoring.
CYRAMZA (ramucirumab) is a VEGFR-2 antagonist; premedicate with antihistamines and acetaminophen before infusion to reduce infusion-related reactions. Monitor blood pressure closely as hypertension is common; hold for severe hypertension. Avoid use in patients with significant bleeding risk or recent thromboembolic events. Do not administer with platinum-based chemotherapy in NSCLC patients with EGFR or ALK mutations unless progression on targeted therapy.
Ellence (epirubicin) is an anthracycline chemotherapeutic agent. It is a vesicant; extravasation can cause severe tissue necrosis. Administer via a freely flowing IV line. Premedicate with antiemetics. Monitor for cardiotoxicity, which is dose-dependent and may be cumulative. Total lifetime dose should not exceed 900-1000 mg/m². Assess cardiac function (LVEF) before and during treatment. Urine may turn red for 1-2 days after administration. Avoid live vaccines.
