INJECTION, POWDER, FOR SOLUTION

**4.2 Posology and method of administration** Entyvio treatment should be initiated and supervised by specialist healthcare professionals experienced in the diagnosis and treatment of ulcerative colitis or Crohn’s disease. Posology – Intravenous Administration _Ulcerative Colitis_ The recommended dose regimen of intravenous vedolizumab is 300 mg administered by intravenous infusion at zero, two and six weeks and then every eight weeks thereafter. Therapy for patients with ulcerative colitis should not be continued if no evidence of therapeutic benefit is observed by Week 14 (see section 5.1 – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_). Some patients who have experienced a decrease in their response may benefit from an increase in dosing frequency to intravenous vedolizumab 300 mg every four weeks. In patients who have responded to treatment with Entyvio, corticosteroids may be reduced and/or discontinued in accordance with standard of care. _Retreatment:_ If therapy is interrupted and there is a need to restart treatment with intravenous vedolizumab, dosing at every four weeks may be considered (see section 5.1 – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_). The treatment interruption period in clinical studies extended up to one year. Efficacy was regained with no evident increase in adverse events or infusion-related reactions during retreatment with intravenous vedolizumab (see section 4.8 – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_). _Crohn’s disease_ The recommended dose regimen of intravenous vedolizumab is 300 mg administered by intravenous infusion at zero, two and six weeks and then every eight weeks thereafter. Patients with Crohn’s disease, who have not shown a response may benefit from a dose of intravenous vedolizumab at Week 10 (see section 4.4 – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_). Continue therapy every eight weeks from Week 14 in responding patients. Therapy for patients with Crohn’s disease should not be continued if no evidence of therapeutic benefit is observed by Week 14 (see section 5.1 – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_). Some patients who have experienced a decrease in their response may benefit from an increase in dosing frequency to intravenous vedolizumab 300 mg every four weeks. In patients who have responded to treatment with Entyvio, corticosteroids may be reduced and/or discontinued in accordance with standard of care. _Retreatment:_ If therapy is interrupted and there is a need to restart treatment with intravenous vedolizumab, dosing at every four weeks may be considered (see section 5.1 – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_). The treatment interruption period in clinical studies extended up to one year. Efficacy was regained with no evident increase in adverse events or infusion-related reactions during retreatment with intravenous vedolizumab (see section 4.8 – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_). Posology – Subcutaneous Administration _Ulcerative Colitis and Crohn’s Disease_ The recommended dose regimen of subcutaneous vedolizumab as a maintenance treatment, following at least two intravenous infusions, is 108 mg administered by subcutaneous injection once every 2 weeks. The first subcutaneous maintenance dose should be administered in place of the next scheduled intravenous dose and every 2 weeks thereafter. See Intravenous Administration section above for intravenous dosing schedule. Insufficient data are available to determine if patients who experience a decrease in response on maintenance treatment with subcutaneous vedolizumab would benefit from an increase in dosing frequency. There are no data on transition of patients from subcutaneous vedolizumab to intravenous vedolizumab during maintenance treatment. _Missed Dose(s)_ If treatment with subcutaneous vedolizumab is interrupted or if a patient misses a scheduled dose(s) of subcutaneous vedolizumab, advise the patient to inject the next subcutaneous dose as soon as possible and then every 2 weeks thereafter. The treatment interruption period in clinical studies extended up to 46 weeks with no evident increase in adverse events or injection site reactions during reinitiation of treatment with subcutaneous vedolizumab. _Corticosteroids_ In patients who have responded to treatment with subcutaneous vedolizumab, corticosteroids may be reduced and/or discontinued in accordance with standard of care. _Paediatric population_ The safety and efficacy of vedolizumab in children aged 0 to 17 years old have not been established. No data are available. _Elderly patients_ No dose adjustment is required in elderly patients. Population pharmacokinetic analyses showed no effect of age (see section 5.2 – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_). _Patients with renal or hepatic impairment_ Vedolizumab has not been studied in these patient populations. No dose recommendations can be made. Method of administration – Intravenous Administration Intravenous vedolizumab is for intravenous use only.
