Pharmacology

Vedolizumab is a humanized monoclonal antibody that binds to the alpha4beta7 integrin and blocks the interaction of alpha4beta7 integrin with mucosal addressin cell adhesion molecule-1 (MAdCAM-1) and inhibits the migration of memory T-lymphocytes across the endothelium into inflamed gastrointestinal parenchymal tissue. The interaction of the alpha4beta7 integrin with MAdCAM-1 has been implicated as an important contributor to the chronic inflammation that is a hallmark of ulcerative colitis and Crohn disease.

Reconstitution

Reconstitute at room temperature with 4.8 mL of sterile water for injection. Gently swirl vial for at least 15 seconds; do not vigorously shake or invert. Allow the solution to sit for up to 20 minutes at room temperature to allow for reconstitution and for any foam to settle; the vial can be swirled and inspected for dissolution during this time. If not fully dissolved after 20 minutes, allow another 10 minutes for dissolution. Do not use the vial if the drug product is not dissolved within 30 minutes. Solution should be clear or opalescent, colorless to light brownish yellow and free of visible particulates. Do not administer reconstituted solution showing uncharacteristic color or containing particulates.

Prior to withdrawing the reconstituted vedolizumab solution from the vial for dilution, gently invert vial 3 times. Add the 5 mL (300 mg) of reconstituted vedolizumab solution to 250 mL of sterile sodium chloride 0.9% and gently mix the infusion bag. Once reconstituted and diluted, use the infusion solution as soon as possible.

Administration

IV: Infuse over 30 minutes. Do not administer by IV push or bolus. Following infusion , flush with 30 mL of sterile 0.9% sodium chloride injection. Observe patients during infusion (until complete) and monitor for hypersensitivity reactions; discontinue if a reaction occurs.

Storage

Refrigerate unopened vials at 2°C to 8°C (36ºF to 46ºF). Retain in original package to protect from light. Following reconstitution and dilution, the infusion solution may be stored for up to 4 hours at 2°C to 8°C (36ºF to 46ºF). Do not freeze. Discard any unused portion.

Warnings/Precautions

Concerns related to adverse effects:

• Hypersensitivity reactions: Hypersensitivity reactions have been reported including anaphylaxis. Allergic reactions including dyspnea, bronchospasm, urticaria, flushing, rash, and increased blood pressure and heart rate have also been observed. Symptom onset may vary from during the infusion, immediately post-infusion, to several hours post-infusion. If serious reactions occur, discontinue administration immediately.

• Infections: Use may be associated with an increased risk for developing infections; most commonly reported infections included upper respiratory and nasal mucosa. Serious infections have also been reported in patients treated, including anal abscess, sepsis (some fatal), tuberculosis, salmonella sepsis, Listeria meningitis, giardiasis, and cytomegaloviral colitis. Therapy is not recommended in patients with uncontrolled, active, severe infections. If a patient develops a serious infection, consider discontinuing therapy. Use with caution in patients with a history of recurring severe infections. Screening for tuberculosis should be considered.

• Liver injury: Elevations of transaminase and/or bilirubin have been reported in patients receiving vedolizumab. Discontinue therapy in patients with jaundice or other evidence of significant liver injury such as fatigue, anorexia, right upper abdominal discomfort, or dark urine.

• Progressive multifocal leukoencephalopathy: Integrin receptor antagonists have been associated with progressive multifocal leukoencephalopathy (PML), a rare and often fatal opportunistic infection of the central nervous system caused by the John Cunningham (JC) virus. Monitor patients for any new onset or worsening of neurological signs and symptoms including progressive weakness on one side of the body or clumsiness of limbs, disturbance of vision, and changes in thinking, memory, and orientation leading to confusion and personality changes. Symptoms may progress over days to weeks and can lead to death or severe disability in weeks to months. If PML is suspected withhold therapy and refer to a neurologist; if confirmed, discontinue therapy permanently.

Other warnings/precautions:

• Immunizations: Patients should be brought up to date with all immunizations according to immunization guidelines before initiating therapy. Live vaccines should not be given concurrently unless the benefits outweigh the risks; there are no data on the secondary transmission of infection by live vaccines with vedolizumab. Non-live vaccines may be given concurrently.

Monitoring Parameters

Observe patients during infusion (until complete) and monitor for hypersensitivity reactions; LFTs; tuberculosis screening according to local practice; signs/symptoms of infection; any new onset or worsening of neurological signs and symptoms

Pregnancy Risk Factor

B

Pregnancy Considerations

Adverse events have not been observed in animal reproduction studies. Monoclonal antibodies are transported across the placenta in a linear fashion as pregnancy progresses, with the largest amount transferred during the third trimester. Any adverse pregnancy effect would likely be greater during the second and third trimesters of pregnancy.

Health care providers are encouraged to enroll women exposed to vedolizumab during pregnancy in a pregnancy exposure registry. Information about the registry can be obtained by calling 1-877-825-3327.

Patient Education

• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)

• Patient may experience back pain, common cold symptoms, joint pain, nausea, rhinitis, pharyngitis, extremity pain, or loss of strength and energy. Have patient report immediately to prescriber signs of infection, signs of infusion reaction, signs of liver problems (dark urine, feeling tired, lack of appetite, nausea, abdominal pain, light-colored stools, vomiting, or yellow skin or eyes), shortness of breath, wheezing, coughing, dizziness, flushing, tachycardia, arrhythmia, severe headache, or signs of progressive multifocal leukoencephalopathy (confusion, depression, trouble with memory, behavioral changes, change in strength on one side, trouble speaking, change in balance, or vision changes) (HCAHPS).

• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
