Administer the first subcutaneous dose in place of the next scheduled intravenous infusion and every two weeks thereafter. Preparation and Administration Instructions: See full prescribing information for complete information on reconstitution, dilution, administration, and storage. ( 2.3 , 2.4 ) 2.1 Important Administration Information Before Initiating ENTYVIO Consider evaluating patients for tuberculosis (TB) infection prior to initiating treatment with ENTYVIO [see Warnings and Precautions (5.2) ]. Update immunizations according to current immunization guidelines [see Warnings and Precautions (5.5) ]. Intravenous Administration ENTYVIO should be administered by a healthcare provider prepared to manage hypersensitivity reactions including anaphylaxis, if they occur [see Warnings and Precautions (5.1) ] . Appropriate monitoring and medical support measures should be available for immediate use. Observe patients during infusion and until the infusion is complete. Reconstitute and dilute ENTYVIO lyophilized powder prior to administration as a 30-minute intravenous infusion [see Dosage and Administration (2.3) ]. Subcutaneous Injection ENTYVIO prefilled syringe and ENTYVIO PEN are intended for subcutaneous use under the guidance and supervision of a healthcare professional. Patients may self-inject or caregivers may inject subcutaneous ENTYVIO using either the ENTYVIO prefilled syringe or ENTYVIO PEN after training in subcutaneous injection technique. Provide proper training to patients and/or caregivers on the subcutaneous injection technique of ENTYVIO. 2.2 Recommended Dosage in Adults with Ulcerative Colitis and Crohn’s Disease Week 0: Administer ENTYVIO 300 mg by intravenous infusion over approximately 30 minutes [ see Dosage and Administration (2.3) ]. Week 2: Administer ENTYVIO 300 mg by intravenous infusion over approximately 30 minutes. Week 6: Patients may remain on ENTYVIO intravenous therapy or switch to subcutaneous injection after receiving two ENTYVIO intravenous doses administered at Week 0 and Week 2. Intravenous Infusion : Administer ENTYVIO 300 mg by intravenous infusion over approximately 30 minutes and then every eight weeks thereafter. Subcutaneous Injection : Administer ENTYVIO 108 mg subcutaneously once every 2 weeks. Discontinue therapy in patients who show no evidence of therapeutic benefit by Week 14. Patients currently receiving and responding to ENTYVIO intravenous therapy after Week 6 may also be switched to subcutaneous injection. Administer the first subcutaneous dose in place of the next scheduled intravenous infusion and every two weeks thereafter. 2.3 Preparation and Administration Instructions for Intravenous Infusion Reconstitution Instructions Remove the flip-off cap from the single-dose vial and wipe with alcohol swab. Reconstitute ENTYVIO vial containing lyophilized powder with 4.8 mL of Sterile Water for injection, 0.9% Sodium Chloride Injection, or Lactated Ringer's Injection, at room temperature (20°C to 25°C [68ºF to 77ºF]), using a syringe with a 21- to 25-gauge needle. Insert the syringe needle into the vial through the center of the stopper and direct the stream of Sterile Water for Injection, 0.9% Sodium Chloride Injection, or Lactated Ringer's Injection, to the glass wall of the vial to avoid excessive foaming. Gently swirl the vial for at least 15 seconds to dissolve the lyophilized powder. 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. Visually inspect the reconstituted ENTYVIO solution for particulate matter and discoloration prior to dilution. 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. Once dissolved, gently invert vial three times. Immediately, withdraw 5 mL (300 mg) of reconstituted ENTYVIO solution using a syringe with a 21- to 25-gauge needle. Discard any remaining portion of the reconstituted solution in the vial. Dilution Instructions Add the 5 mL (300 mg) of reconstituted ENTYVIO solution to 250 mL of 0.9% Sodium Chloride Injection, or Lactated Ringer's Injection, and gently mix the infusion bag. Do not add other medicinal products to the prepared infusion solution or intravenous infusion set. Once reconstituted and diluted, use the infusion solution as soon as possible. Discard any unused portion of the infusion solution . Administration Instructions After the infusion is complete, flush with 30 mL of 0.9% Sodium Chloride Injection, or Lactated Ringer's Injection. Storage and Stability Specific storage conditions and timing for the reconstituted solution in vial and diluted solution in the infusion bag are outlined in Table 1 . Do not freeze the reconstituted solution in the vial or the diluted solution in the infusion bag. Table 1. Storage Instructions for Reconstituted Solution in Vial and Diluted Solution in Infusion Bag Solution Storage Conditions Refrigeration (2°C to 8°C [36°F to 46°F]) Room Temperature (20°C to 25°C [68°F to 77°F]) Reconstituted Solution (in Sterile Water for Injection, 0.9% Sodium Chloride Injection, or Lactated Ringer's Injection, inside vial) 8 hours Use immediately after reconstitution Diluted Solution (in 0.9% Sodium Chloride Injection) 24 hours This time assumes the reconstituted solution is immediately diluted in the 0.9% Sodium Chloride Injection, or Lactated Ringer's Injection, and held in the infusion bag only. Any time that the reconstituted solution was held in vial should be subtracted from the time the solution may be held in the infusion bag. , This period may include up to 12 hours at room temperature (20°C to 25°C [68°F to 77°F]). 12 hours Diluted Solution (in Lactated Ringer's Injection) 6 hours Use immediately after dilution The combined storage time of reconstituted ENTYVIO solution in the vial and the diluted solution in the infusion bag with 0.9% Sodium Chloride Injection, is a total of 12 hours at room temperature (20°C to 25°C [68°F to 77°F]) or 24 hours refrigerated (2°C to 8°C [36°F to 46°F]). This combined storage time may include up to eight hours of the reconstituted solution in the vial at 2°C to 8°C. The combined storage time of reconstituted ENTYVIO solution in the vial and the diluted solution in the infusion bag with Lactated Ringer's Injection, is a total of six hours refrigerated (2°C to 8°C [36°F to 46°F]). 2.4 Preparation and Administration Instructions for Subcutaneous Injection Inspect the solution visually for particulate matter and discoloration prior to administration. ENTYVIO in prefilled syringe or ENTYVIO PEN should be a clear to moderately opalescent, colorless to slightly yellow solution. Do not use ENTYVIO prefilled syringes or ENTYVIO PENs with visible particulate matter or discoloration. Administer each subcutaneous injection at a different anatomic location (such as thighs, any quadrant of abdomen, or upper arms) than the previous injection. Administration of ENTYVIO in the back of upper arm may only be performed by a healthcare professional or caregiver. Do not inject into moles, scars, bruises, or areas where the skin is tender, erythematous, or indurated. Missed Subcutaneous Dose If treatment with subcutaneous ENTYVIO is interrupted or if a scheduled dose(s) of subcutaneous ENTYVIO is missed, inject the next subcutaneous dose as soon as possible and then every 2 weeks thereafter. In the event of incomplete dose administration (i.e., patient attempts administration of dose with ENTYVIO PEN, however it is uncertain if a full dose was administered), instruct the patient to call their pharmacy or healthcare provider.

6 ADVERSE REACTIONS The following topics are also discussed in detail in the Warnings and Precautions section: Infusion-Related Reactions and Hypersensitivity Reactions [see Warnings and Precautions (5.1) ] Infections [see Warnings and Precautions (5.2) ] Progressive Multifocal Leukoencephalopathy [see Warnings and Precautions (5.3) ] Liver Injury [see Warnings and Precautions (5.4) ] Most common adverse reactions (incidence ≥3% and ≥1% higher than placebo) are: nasopharyngitis, headache, arthralgia, nausea, pyrexia, upper respiratory tract infection, fatigue, cough, bronchitis, influenza, back pain, rash, pruritus, sinusitis, oropharyngeal pain, and pain in extremities. ( 6.1 ) Adverse reactions with subcutaneous ENTYVIO are similar to those reported with intravenous ENTYVIO with the exception of injection site reactions reported with subcutaneous ENTYVIO. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Takeda Pharmaceuticals U.S.A., Inc. at 1-877-TAKEDA-7 (1-877-825-3327) or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The data described below reflect exposure to intravenous ENTYVIO in 3,326 patients and healthy volunteers in clinical trials, including 1,396 exposed for greater than one year, and 835 exposed for greater than two years. Intravenous Infusion The safety data described in Table 2 are derived from four controlled Phase 3 trials (UC Trials I and II and CD Trials I and III); data from adult patients receiving open-label intravenous ENTYVIO treatment at Weeks 0 and 2 (prior to entry into UC Trial II and CD Trial III) and from Weeks 6 to 52 (non-responders at Week 6 of UC Trial I and CD Trial I) are included [see Clinical Studies (14.1 , 14.2) ] . In these trials, 1,434 patients received ENTYVIO 300 mg intravenously for up to 52 weeks, and 297 patients received placebo for up to 52 weeks. Of these, 769 patients had ulcerative colitis and 962 patients had Crohn's disease. Patients were exposed for a mean duration of 259 days (UC Trials I and II) and 247 days (CD Trials I and III). Adverse reactions were reported in 52% of patients treated with intravenous ENTYVIO and 45% of patients treated with placebo (UC Trials I and II: 49% with ENTYVIO and 37% with placebo; CD Trials I and III: 55% with ENTYVIO and 47% with placebo). Serious adverse reactions were reported in 7% of patients treated with intravenous ENTYVIO compared to 4% of patients treated with placebo (UC Trials I and II: 8% with ENTYVIO and 7% with placebo; CD Trials I and III: 12% with ENTYVIO and 9% with placebo). The most common adverse reactions (reported by ≥3% of patients treated with intravenous ENTYVIO in the UC Trials I and II and CD Trials I and III combined group and ≥1% higher than in combined placebo group) were nasopharyngitis, headache, arthralgia, nausea, pyrexia, upper respiratory tract infection, fatigue, cough, bronchitis, influenza, back pain, rash, pruritus, sinusitis, oropharyngeal pain, and pain in extremities (Table 2) . Table 2. Adverse Reactions in ≥3% of Intravenous ENTYVIO-Treated Adult Patients and ≥1% Higher than in Placebo (UC Trials I and II Data from patients receiving open-label intravenous ENTYVIO treatment at Weeks 0 and 2 (prior to entry into UC Trial II and CD Trial III) and from Weeks 6 to 52 (non-responders at Week 6 of UC Trial I and CD Trial I) are included. and CD Trials I and III ) Adverse Reaction ENTYVIO IV Patients who received ENTYVIO for up to 52 weeks.

Infusion-Related Reactions and Hypersensitivity Reactions Serious infusion-related reactions and hypersensitivity reactions including anaphylaxis have been reported following intravenous ENTYVIO administration in clinical trials [see Warnings and Precautions (5.1) ] . In UC Trials I and II and CD Trials I and III, one case of anaphylaxis [one out of 1,434 patients treated with intravenous ENTYVIO (0.07%)] was reported by a Crohn's disease patient during the second infusion (symptoms reported were dyspnea, bronchospasm, urticaria, flushing, rash, and increased blood pressure and heart rate) and was managed with discontinuation of infusion and treatment with antihistamine and intravenous hydrocortisone. In UC Trials I and II and CD Trials I and III, 4% of patients treated with intravenous ENTYVIO and 3% of patients treated with placebo experienced an infusion-related reaction (IRR). The most frequently observed IRRs in the patients treated with intravenous ENTYVIO (reported more than twice) were nausea, headache, pruritus, dizziness, fatigue, infusion-related reaction, pyrexia, urticaria, and vomiting (each of these adverse reactions occurred in <1% in all patients treated with intravenous ENTYVIO) and no individual adverse reaction reported occurred at a rate above 1%. These reactions generally occurred within the first two hours after the infusion and resolved with no treatment or following antihistamine and/or IV hydrocortisone treatment. Less than 1% of patients treated with intravenous ENTYVIO had IRRs assessed by the investigator as severe, and IRRs requiring discontinuation of study treatment occurred in <1%. In clinical trials, for patients with mild IRRs or hypersensitivity reactions, physicians were allowed to pretreat with standard medical treatment (e.g., antihistamine, hydrocortisone, and/or acetaminophen) prior to next infusion. Infections In UC Trials I and II and CD Trials I and III, the rate of infections was 0.85 per patient-year in the patients treated with intravenous ENTYVIO and 0.7 per patient-year in the patients treated with placebo [see Warnings and Precautions (5.2) ] . The infections consisted primarily of nasopharyngitis, upper respiratory tract infection, sinusitis, and urinary tract infection. Two percent of patients discontinued intravenous ENTYVIO due to infections. In UC Trials I and II and CD Trials I and III, the rate of serious infections was 0.07 per patient-year in patients treated with intravenous ENTYVIO and 0.06 per patient-year in patients treated with placebo. Serious infections were more common in Crohn's disease patients than ulcerative colitis patients, and anal abscesses were the most frequently reported serious adverse reaction in Crohn's disease patients. Over 48 months, there was no increase in the rate of serious infections. In controlled- and open-label long-term extension trials in adults treated with intravenous ENTYVIO, serious infections have been reported, including anal abscess, sepsis (some fatal), tuberculosis, salmonella sepsis, Listeria meningitis, giardiasis, and cytomegaloviral colitis. In UC Trials I and II and CD Trials I and III, sepsis, including bacterial sepsis and septic shock, was reported in four of 1,434 (0.3%) patients treated with intravenous ENTYVIO and in two of 297 patients treated with placebo (0.7%). During these trials, two Crohn's disease patients treated with intravenous ENTYVIO died due to reported sepsis or septic shock; both patients had significant comorbidities and a complicated hospital course that contributed to the deaths. In an open label, long-term extension trial, additional cases of sepsis (some fatal), including bacterial sepsis and septic shock, were reported. The rate of sepsis in patients with ulcerative colitis or Crohn's disease receiving intravenous ENTYVIO was two per 1,000 patient-years. In clinical trials, all patients were screened for tuberculosis. One case of latent, pulmonary tuberculosis was diagnosed during the controlled trials with intravenous ENTYVIO. Additional cases of pulmonary tuberculosis were diagnosed during the open-label trial. All of these observed cases occurred outside the United States (U.S.), and none of the patients had extrapulmonary manifestations. Liver Injury There have been reports of elevations of transaminase and/or bilirubin in patients receiving intravenous ENTYVIO [see Warnings and Precautions (5.4) ] . In UC Trials I and II and CD Trials I and III, three patients reported serious adverse reactions of hepatitis, manifested as elevated transaminases with or without elevated bilirubin and symptoms consistent with hepatitis (e.g., malaise, nausea, vomiting, abdominal pain, anorexia). These adverse reactions occurred following two to five intravenous ENTYVIO doses; however, based on case report information it is unclear if the reactions indicated drug-induced or autoimmune etiology. All patients recovered following discontinuation of therapy with some requiring corticosteroid treatment. In controlled trials, the incidence of ALT and AST elevations ≥3× ULN was <2% in patients treated with intravenous ENTYVIO and in patients treated with placebo. In the open-label trial, one additional case of serious hepatitis was observed. Malignancies In UC Trials I and II and CD Trials I and III, malignancies (excluding dysplasia and basal cell carcinoma) were reported in six of 1,434 (0.4%) patients treated with intravenous ENTYVIO, including colon cancer (n=2), transitional cell carcinoma (n=1), breast cancer (n=1), carcinoid tumor of the appendix (n=1), and squamous cell carcinoma (n=1). Malignancy was reported in one of 297 (0.3%) patients treated with placebo (squamous cell carcinoma). Malignancies (excluding dysplasia and basal cell carcinoma) observed during the ongoing open-label long-term extension trial included B-cell lymphoma, breast cancer, colon cancer, malignant hepatic neoplasm, malignant lung neoplasm, malignant melanoma, lung cancer of primary neuroendocrine carcinoma, renal cancer, and squamous cell carcinoma. Overall, the number of malignancies in the clinical trials was small; however, long-term exposure was limited. Subcutaneous Injection after Two Intravenous Doses of ENTYVIO ENTYVIO was administered as a subcutaneous injection in adult patients with ulcerative colitis and Crohn’s disease in double-blind, placebo-controlled clinical trials (SC UC Trial and SC CD Trial, respectively). Patients who achieved clinical response following two doses of ENTYVIO administered as an intravenous infusion at Week 0 and Week 2 were randomized 2:1 at Week 6 to ENTYVIO as a subcutaneous injection (N=106) or placebo (N=56) (SC UC Trial) and as a subcutaneous injection (N=275) or placebo (N=134) (SC CD Trial) [see Clinical Studies (14.1 , 14.2) ] . The safety profile for up to 52 weeks of total treatment was similar between patients who were switched to ENTYVIO as a subcutaneous injection in SC UC and SC CD clinical trials and patients in UC and CD clinical trials who received ENTYVIO as an intravenous infusion ( Table 2 ) except for injection site reactions, which were reported with subcutaneous ENTYVIO. Injection site reactions with subcutaneous ENTYVIO were reported in 10% (11/106) of patients in SC UC Trial, including injection site erythema, rash, pruritus, swelling, bruising, and hematoma. Injection site reactions with subcutaneous ENTYVIO were reported in 3% (8/275) of patients in SC CD Trial, including injection site erythema, pruritus, urticaria, pain, rash, and edema. Live and Oral Vaccines There are no data on the secondary transmission of infection by live vaccines in patients receiving ENTYVIO. In a placebo-controlled study of healthy volunteers, 61 subjects were given a single intravenous ENTYVIO 750 mg dose (2.5 times the recommended dose), and 62 subjects received placebo followed by intramuscular vaccination with Hepatitis B surface antigen and oral cholera vaccine. After intramuscular vaccination with three doses of recombinant Hepatitis B surface antigen, those treated with intravenous ENTYVIO did not have lower rates of protective immunity to Hepatitis B virus. However, those exposed to intravenous ENTYVIO did have lower seroconversion rates and anti-cholera titers relative to placebo after receiving the two doses of a killed, oral cholera vaccine. The impact on other oral vaccines and on nasal vaccines in patients is unknown. 6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of ENTYVIO. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Immune system disorders: Anaphylaxis [see Warnings and Precautions (5.1) ]. Gastrointestinal system disorders: Acute pancreatitis. Respiratory, thoracic, and mediastinal disorders: Interstitial lung disease, pneumonitis.

12.3 Pharmacokinetics Similar pharmacokinetics were observed in ulcerative colitis and Crohn's disease patients administered 300 mg ENTYVIO as a 30-minute intravenous infusion on Weeks 0, 2, and 6, and then every eight weeks up to Week 52 (Table 3) . Table 3. Mean ± SD Vedolizumab Concentrations in Patients Data from patients in UC Trials I and II and CD Trials I and III with pharmacokinetic data available; data from patients with anti-vedolizumab antibody were excluded. with Ulcerative Colitis and Crohn's Disease Patient Population Weeks 0, 2, and 6 ENTYVIO 300 mg Intravenously After Week 6 to 52 ENTYVIO 300 mg Intravenously Every 8 Weeks Trough Serum Concentration at Week 6 (mcg/mL) Trough Serum Concentration at Week 46 Steady-state trough serum concentration. (mcg/mL) Ulcerative Colitis 26.3 ± 12.9 (N=210) 11.2 ± 7.2 (N=77) Crohn's Disease 27.4 ± 19.2 (N=198) 13.0 ± 9.1 (N=72) In ulcerative colitis and Crohn’s disease patients, administered 300 mg ENTYVIO as a 30-minute intravenous infusion on Weeks 0 and 2, followed by 108 mg ENTYVIO as a subcutaneous injection every 2 weeks starting from Week 6, the mean steady state serum trough concentrations were 35.8 mcg/mL (SD ± 15.2) and 31.4 mcg/mL (SD ± 14.7), respectively. The bioavailability of vedolizumab following a 108 mg single-dose subcutaneous injection relative to a 300 mg single-dose intravenous infusion in healthy subjects was approximately 75%. Following a 108 mg single-dose subcutaneous injection in healthy subjects, the median T max was 7 days with a range of 3 to 14 days and the mean C max was 15.4 mcg/mL (SD ± 3.2). Vedolizumab clearance depends on both linear and nonlinear pathways; the nonlinear clearance decreases with increasing concentrations. Population pharmacokinetic analyses indicated that the linear clearance was approximately 0.16 L/day, the serum half-life was approximately 26 days, and the distribution volume was approximately 5 L. Vedolizumab was not detected in the cerebrospinal fluid (CSF) of 14 healthy subjects at five weeks after a single intravenous administration of 450 mg ENTYVIO (1.5 times the recommended dosage). Specific Populations Population pharmacokinetic analysis showed that the severity of disease state, body weight, prior treatment with TNF blocker therapy, age (18 to 78 years), serum albumin, coadministered immunomodulators (including azathioprine, 6-mercaptopurine, methotrexate), and coadministered aminosalicylates did not have a clinically meaningful effect on the pharmacokinetics of ENTYVIO. Pharmacokinetics of vedolizumab in patients with renal or hepatic insufficiency have not been studied.
