Introduction

Antineoplastic agent; a recombinant human IgG₁ monoclonal antibody and vascular endothelial growth factor receptor (VEGFR)-2 antagonist.

Uses for Ramucirumab

Gastric Cancer

Used alone or in combination with paclitaxel for the treatment of advanced or metastatic gastric adenocarcinoma, including adenocarcinoma of the gastroesophageal junction, that has progressed during or following fluoropyrimidine- or platinum-based chemotherapy (designated an orphan drug by FDA for treatment of this cancer ).

Improved overall and progression-free survival demonstrated with ramucirumab compared with placebo; improved overall and progression-free survival and objective response rate demonstrated with ramucirumab-paclitaxel compared with placebo-paclitaxel.

Non-small Cell Lung Cancer (NSCLC)

Used in combination with docetaxel for the treatment of metastatic NSCLC that has progressed during or following platinum-based chemotherapy. Patients with epidermal growth factor receptor (EGFR)- or anaplastic lymphoma kinase (ALK)-positive tumors also should have documented disease progression during or following an FDA-labeled anti-EGFR or anti-ALK therapy prior to initiating therapy with ramucirumab.

Improved overall and progression-free survival and objective response rate demonstrated with ramucirumab-docetaxel compared with placebo-docetaxel.

Colorectal Cancer

Used in combination with fluorouracil, leucovorin (folinic acid), and irinotecan (the combination of fluorouracil, leucovorin, and irinotecan is hereafter referred to as FOLFIRI in this monograph) for the treatment of metastatic colorectal cancer that has progressed during or following combination therapy with oxaliplatin, bevacizumab, and a fluoropyrimidine.

Improved overall and progression-free survival demonstrated with ramucirumab-FOLFIRI compared with placebo-FOLFIRI therapy.

Ramucirumab Dosage and Administration

General

• Administer in setting where adequate monitoring can be performed and appropriate medical support for treating infusion-related reactions is available.

• To minimize risk of infusion-related reactions, premedication with an antihistamine (e.g., IV diphenhydramine) recommended prior to each infusion. If grade 1 or 2 infusion-related reaction occurred during a previous infusion, also administer dexamethasone (or equivalent) and acetaminophen prior to subsequent infusions. (See Infusion-related Effects under Cautions.)

• Obtain ramucirumab through a limited network of specialty pharmacies. Contact manufacturer at 800-545-5979 or consult the Cyramza website ([Web]) for availability and ordering information.

Arterial Thromboembolic Events

Severe, sometimes fatal, arterial thromboembolic events (including MI, cardiac arrest, cerebrovascular accident, and cerebral ischemia) reported.

Permanently discontinue therapy if severe arterial thromboembolic event occurs.

Hypertension

Grade 3 or 4 hypertension reported.

Control hypertension prior to initiating ramucirumab therapy. Monitor BP every 2 weeks or more frequently as clinically indicated during therapy.

If severe hypertension occurs, interrupt therapy until hypertension is controlled. Permanently discontinue ramucirumab in patients with clinically important hypertension that is not controlled with antihypertensive therapy or in patients who develop hypertensive crisis or hypertensive encephalopathy.

Infusion-related Effects

Infusion-related reactions (e.g., bronchospasm, supraventricular tachycardia, hypotension, rigors/tremors, back pain/spasms, chest pain and/or tightness, chills, flushing, dyspnea, wheezing, hypoxia, paresthesia), sometimes severe, reported.

Generally occur more frequently during or following the first 2 infusions.

Premedication recommended prior to each infusion. (See General under Dosage and Administration.)

Monitor patients during infusions for manifestations of infusion-related reactions.

If infusion-related reactions occur, reduce infusion rate or discontinue therapy depending on severity of reaction. (See Infusion-related Effects under Dosage and Administration.)

Hepatic Effects

Actions

• Binds specifically to VEGFR-2 and blocks the interaction of VEGFR-2 with its ligands (VEGFR-A, VEGFR-C, and VEGFR-D), resulting in inhibition of VEGFR-stimulated activation of both VEGFR-2 and downstream signaling pathways.

• The VEGFR signaling pathway plays an important role in tumor angiogenesis, tumor growth, and metastatic spread.

• Binding of ramucirumab to VEGFR-2 blocks ligand-induced phosphorylation and activation of the receptor in vitro.

• Inhibits VEGFR-mediated endothelial cell proliferation and migration in vitro.

• Inhibits angiogenesis in vivo.

Advice to Patients

• Risk of severe bleeding. Importance of informing clinician of any episodes or symptoms of bleeding (e.g., lightheadedness).

• Risk of arterial thromboembolic events.

• Risk of hypertension. Importance of receiving routine monitoring of BP and informing clinician if BP is elevated or if manifestations of hypertension (e.g., severe headache, lightheadedness, neurologic symptoms) occur.

• Importance of informing clinician if severe diarrhea, vomiting, or severe abdominal pain occurs.

• Risk of wound healing complications. Importance of informing clinician of any scheduled surgery.

• Risk of fetal or neonatal toxicity and miscarriage. Necessity of advising women receiving ramucirumab to use an effective method of contraception during and for ≥3 months after the last dose of ramucirumab. Importance of immediately informing clinician if the patient becomes pregnant during therapy. If pregnancy occurs, apprise patient of potential hazard to the fetus.

• Importance of discontinuing nursing while receiving ramucirumab therapy.

• Importance of informing clinicians of existing or contemplated concomitant therapy, including prescription and OTC drugs and dietary or herbal supplements (e.g., NSAIAs), as well as any concomitant illnesses (e.g., hypertension, hepatic disease).

• Importance of informing patients of other important precautionary information. (See Cautions.)
