4.2    Posology and method of administration

Treatment should be initiated and supervised by specialist healthcare professionals experienced in the diagnosis and treatment of ulcerative colitis or Crohn’s disease (see section 4.4). Patients should be given the package leaflet.

Posology

Ulcerative colitis and Crohn’s disease
The recommended dose regimen of subcutaneous vedolizumab as a maintenance treatment, following at least 2 intravenous infusions, is 108 mg administered by subcutaneous injection once every 2 weeks. The first subcutaneous dose should be administered in place of the next scheduled intravenous dose and every 2 weeks thereafter.
For the intravenous dose regimen, see section 4.2 of the Entyvio 300 mg powder for concentrate for solution for infusion Physician Information.

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.

In patients who have responded to treatment with vedolizumab, corticosteroids may be reduced and/or discontinued in accordance with standard of care.

Retreatment and missed dose(s)
If treatment with subcutaneous vedolizumab is interrupted or if a patient misses a scheduled dose(s) of subcutaneous vedolizumab, patient should be advised to inject the next subcutaneous dose as soon as possible and then every 2 weeks thereafter. The treatment interruption period in clinical trials extended up to 46 weeks with no evident increase in adverse reactions or injection site reactions during re-initiation of treatment with subcutaneous vedolizumab (see section 4.8).

Special populations

Elderly patients
No dose adjustment is required in elderly patients. Population pharmacokinetic analyses showed no effect of age (see section 5.2).

Patients with renal or hepatic impairment

Vedolizumab has not been studied in these patient populations. No dose recommendations can be made.

Paediatric population

No data are available.
Method of administration

Entyvio solution for injection (in a pre-filled syringe or a pre-filled pen) is for subcutaneous injection only.

After proper training on correct subcutaneous injection technique, a patient or caregiver may inject with subcutaneous vedolizumab if their physician determines it is appropriate.
