Introduction

Recombinant humanized anti-α4β7-integrin monoclonal antibody; an immunomodulatory agent that selectively inhibits lymphocyte recruitment to the GI tract.

Uses for Vedolizumab

Ulcerative Colitis

Treatment of moderately to severely active ulcerative colitis; used to induce and maintain clinical response and clinical remission, improve endoscopic appearance of mucosa, and achieve corticosteroid-free remission in adults with moderately to severely active disease.

Crohn's Disease

Treatment of moderately to severely active Crohn's disease; used to achieve clinical response, clinical remission, and corticosteroid-free remission in adults with moderately to severely active disease.

Vedolizumab Dosage and Administration

General

  • Monitor patients closely for infusion-related or hypersensitivity reactions during vedolizumab infusions. (See Hypersensitivity and Infusion-related Reactions under Cautions.)

    Concomitant Therapy
  • Aminosalicylates, corticosteroids, and immunosuppressive agents (azathioprine, mercaptopurine) could be continued in clinical studies in patients with ulcerative colitis.

  • Aminosalicylates, corticosteroids, antibiotics, and immunosuppressive agents (azathioprine, mercaptopurine, or methotrexate) could be continued in clinical studies in patients with Crohn’s disease.

Administration

IV Administration

For solution compatibility information, see Compatibility under Stability.

Administer by IV infusion. Do not administer by rapid IV injection (IV push or bolus).

Do not mix with or administer through the same administration set with other drugs.

Flush IV line with 30 mL of 0.9% sodium chloride injection or lactated Ringer's injection after the infusion is complete.

Lyophilized powder must be reconstituted at room temperature and diluted prior to administration.

Reconstitution

Reconstitute vedolizumab lyophilized powder by adding 4.8 mL of sterile water for injection (using a syringe with a 21- to 25-gauge needle) to a 300-mg vial to provide a solution containing 60 mg/mL. Direct diluent toward wall of vial to avoid excessive foaming.

Gently swirl vial for at least 15 seconds to dissolve powder. Do not shake vigorously or invert. Allow solution to stand for up to 20 minutes at room temperature to allow for reconstitution and for any foam to settle. Vial can be swirled and inspected for dissolution during this time. If not fully dissolved within 20 minutes, allow an additional 10 minutes. Do not use vial if drug is not dissolved within 30 minutes.

May refrigerate reconstituted solution in vial for up to 8 hours prior to further dilution; however, maximum storage time for reconstituted solution in vial may be limited by diluent selected to prepare the final infusion solution. (See Storage under Stability.)

Dilution

Gently invert vial 3 times, then immediately withdraw 5 mL (300 mg) of reconstituted solution (using a syringe with a 21- to 25-gauge needle). Add the reconstituted solution to an infusion bag containing 250 mL of 0.9% sodium chloride injection or lactated Ringer's injection and mix gently.

Storage time for diluted solution depends on storage conditions and diluent. (See Storage under Stability.)

Discard any unused portions of reconstituted or diluted solutions.

Rate of Administration

Administer by IV infusion over 30 minutes.

Cautions for Vedolizumab

Contraindications

  • Known history of serious or severe hypersensitivity reaction (e.g., dyspnea, bronchospasm, urticaria, flushing, rash, increased heart rate) to the drug or any ingredient in the formulation.

Warnings/Precautions

Hypersensitivity and Infusion-related Reactions

Infusion-related and hypersensitivity reactions, including anaphylaxis, dyspnea, bronchospasm, urticaria, flushing, rash, and increased BP and heart rate, reported. Infusion-related reactions also may include nausea, headache, pruritus, dizziness, fatigue, pyrexia, and vomiting.

Reactions may occur with the first infusion or with subsequent infusions; time of onset may be variable (during or up to several hours after an infusion).

Clinicians should be prepared to treat hypersensitivity and infusion-related reactions. Ensure appropriate equipment and agents for treating such reactions are available for immediate use, and monitor patient until infusion is completed. If anaphylaxis or other serious infusion-related or hypersensitivity reactions occur, immediately discontinue the infusion and initiate appropriate treatment.

In clinical trials, patients who experienced a mild infusion-related or hypersensitivity reaction to the drug could receive premedication (e.g., antihistamine, hydrocortisone, and/or acetaminophen) prior to subsequent infusions.

Infectious Complications

Increased risk of infections. Most common infections are nasopharyngeal and upper respiratory tract infections. However, serious infections (e.g., anal abscess, sepsis [sometimes fatal], tuberculosis, Salmonella sepsis, Listeria meningitis, giardiasis, cytomegaloviral colitis) also reported, more commonly in patients with Crohn's disease than in those with ulcerative colitis.

In clinical trials in ulcerative colitis and Crohn's disease, rate of infection was 0.85 or 0.7 per patient-year in patients receiving vedolizumab or placebo, respectively; rate of serious infection was 0.07 or 0.06 per patient-year, respectively. Rate of serious infection did not increase over 48 months.

Delay initiation of vedolizumab until any active severe infection has been controlled. If severe infection develops during therapy, consider interrupting vedolizumab therapy.

Exercise caution when considering use in patients with a history of recurring severe infections.

Consider screening for active or latent tuberculosis infection.

Progressive Multifocal Leukoencephalopathy (PML)

PML, an opportunistic infection of the brain caused by the JC virus, reported in patients receiving systemic immunosuppressive agents, including natalizumab, an anti-α4-integrin monoclonal antibody. PML generally occurs only in immunocompromised patients and usually progresses to death or severe disability. Also reported during postmarketing experience in a vedolizumab-treated patient with multiple contributory factors (e.g., HIV infection with CD4+ T-cell count of 300 cells/mm3 and prior and concomitant immunosuppression). Although considered unlikely, risk of PML in vedolizumab-treated patients cannot be ruled out.

Monitor for any new or worsening neurologic manifestations (see Advice to Patients). If PML is suspected, withhold drug and refer patient to a neurologist. Permanently discontinue if PML is confirmed.

Hepatic Effects

Increases in serum ALT and AST concentrations and/or bilirubin concentrations, including several cases of hepatitis, reported following 2–5 doses of the drug; unclear whether reactions were drug induced or autoimmune. All patients recovered following drug discontinuance, although some patients also required corticosteroid treatment.

Discontinue vedolizumab in patients with jaundice or other evidence of clinically important hepatic injury.

Immunization

Administer all appropriate vaccines as recommended by current immunization guidelines prior to initiation of vedolizumab.

Patients receiving vedolizumab may receive inactive vaccines (e.g., parenteral influenza virus vaccine inactivated) and may receive live vaccines if potential benefits justify possible risks. (See Interactions.)

Malignancies

Malignancies (excluding dysplasia and basal cell carcinoma) reported in 0.4 or 0.3% of patients receiving vedolizumab or placebo, respectively, during clinical trials in ulcerative colitis or Crohn's disease. Malignancies also reported during extension phases of the trials; however, data regarding effects of long-term exposure to the drug are limited.

Immunogenicity

Formation of antibodies, including neutralizing antibodies, to vedolizumab reported. Presence of persistently positive anti-vedolizumab antibodies associated with undetectable or negligible serum concentrations of the drug and failure to achieve clinical remission.

Specific Populations

Pregnancy

Available pharmacovigilance data, pregnancy registry data, and data from case reports and cohort studies in pregnant women have not identified a vedolizumab-associated risk of major birth defects, spontaneous abortion, or adverse maternal or fetal outcomes. No fetal harm observed in animal reproduction studies.

Increased disease activity in women with inflammatory bowel disease may increase the risk of adverse pregnancy outcomes (e.g., preterm delivery, low birth weight, small size for gestational age at birth).

Pregnancy registry at 877-825-3327.

Use during pregnancy could affect immune responses in neonates and infants exposed to the drug in utero. Clinical importance of low concentrations of the drug in infants exposed in utero is unknown. Safety of administering live vaccines to infants exposed to the drug in utero also is unknown.

Lactation

Vedolizumab distributes into human milk in low concentrations. Effects on nursing infants, including potential effects of local GI exposure or systemic exposure (expected to be low), are unknown; effects on milk production also unknown.

Consider developmental and health benefits of breast-feeding along with the mother's clinical need for vedolizumab and any potential adverse effects on the breast-fed infant from the drug or underlying maternal condition.

Pediatric Use

Safety and efficacy not established in pediatric patients.

Safety of administering live vaccines to infants exposed to vedolizumab in utero is unknown. (See Pregnancy under Cautions.)

Geriatric Use

Insufficient experience in patients ≥65 years of age to determine whether geriatric patients respond differently than younger adults; however, no overall differences in efficacy and safety observed.

Common Adverse Effects

Nasopharyngitis, headache, arthralgia, nausea, pyrexia, upper respiratory tract infection, fatigue, cough, bronchitis, influenza, back pain, rash, pruritus, sinusitis, oropharyngeal pain, pain in extremities.

Interactions for Vedolizumab

Vaccines

Inactivated vaccines: For IM hepatitis B vaccine and oral inactivated cholera vaccine (not commercially available in US), see Specific Drugs under Interactions. Effect of vedolizumab on immune responses to other oral or intranasal vaccines not known. Manufacturer states patients receiving vedolizumab may receive inactivated vaccines.

Live vaccines: No data on secondary transmission of infection by live vaccines in patients receiving vedolizumab. Manufacturer states patients receiving vedolizumab may receive live vaccines if potential benefits justify possible risks.

Vedolizumab Pharmacokinetics

Distribution

Extent

Not known whether vedolizumab distributes into human milk.

Not detected in CSF at 5 weeks after single IV dose (450 mg).

Elimination

Half-life

Approximately 25 days at 300-mg dose.

Clearance dependent on linear and nonlinear pathways; nonlinear clearance decreases with increasing concentrations.

Special Populations

Pharmacokinetics similar in patients with ulcerative colitis and those with Crohn’s disease.

Pharmacokinetics not formally studied in patients with renal or hepatic impairment.

Disease severity, body weight, prior treatment with TNF blocking agents, age (within range of 18–78 years), serum albumin concentration, and concomitant therapy (azathioprine, mercaptopurine, methotrexate, aminosalicylates) did not have a clinically meaningful effect on pharmacokinetics.

Presence of persistently positive anti-vedolizumab antibodies may reduce serum vedolizumab concentrations to undetectable or negligible levels. (See Immunogenicity under Cautions.)

Actions

  • Binds specifically to α4β7 integrin, a protein expressed on the surface of a small subset of memory T-lymphocytes that preferentially migrate into the GI tract. Binding of vedolizumab to α4β7 integrin blocks interaction of α4β7 integrin with mucosal addressin cell adhesion molecule-1 (MAdCAM-1), which is expressed mainly on vascular endothelial cells in the GI tract, and inhibits migration of memory T-lymphocytes across the endothelium into inflamed GI parenchymal tissue.

  • Interaction of α4β7 integrin with MAdCAM-1 implicated as an important contributor to the chronic inflammation of ulcerative colitis and Crohn's disease.

  • Does not bind to or inhibit the function of α4β1 and αEβ7 integrins; does not antagonize the interaction of α4 integrins with vascular cell adhesion molecule-1 (VCAM-1).

  • Appears to exert a more selective effect on the GI tract than does natalizumab, which binds to α4 subunits of α4β1 and α4β7 integrins expressed on the surface of all leukocytes except neutrophils.

Advice to Patients

  • Importance of reviewing the manufacturer's patient information (medication guide).

  • Importance of immediately reporting symptoms consistent with a hypersensitivity reaction (e.g., rash, pruritus, shortness of breath or difficulty breathing, wheezing, dizziness, flushing, palpitations, swelling of lips, tongue, throat, or face) that occur during or following IV infusion of the drug.

  • Increased risk of infection. Importance of informing clinician of any signs or symptoms of infection (e.g., fever, chills, cough, dyspnea, fatigue, red or painful skin or sores, myalgia, rhinorrhea, sore throat, pain on urination).

  • Inform patients that PML has occurred in patients receiving some integrin receptor antagonist and systemic immunosuppressive agents. Importance of immediately informing clinician of any new or worsening neurologic manifestations (e.g., progressive weakness on one side of body or clumsiness of limbs; changes in speech or walking; vision changes; changes in thinking, memory, and orientation leading to confusion and personality changes).

  • Possibility of increased ALT/AST concentrations, with or without elevated bilirubin concentrations. Importance of promptly informing clinician of any symptoms suggestive of hepatic injury (e.g., fatigue, anorexia, right upper abdominal discomfort, dark urine, jaundice).

  • Importance of reviewing vaccination status with clinician and receiving all age-appropriate vaccines prior to initiation of vedolizumab therapy.

  • Importance of informing clinician of existing or contemplated concomitant therapy, including prescription and OTC drugs and dietary or herbal supplements, as well as any concomitant illnesses (e.g., liver disease, tuberculosis or other infection) or any history of recurrent infections.

  • Importance of women informing their clinician if they are or plan to become pregnant or plan to breast-feed. Inform pregnant women that the manufacturer has established a registry to monitor pregnancy outcomes. (See Pregnancy Under Cautions.)

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