Instructions for preparation and administration

Reconstitution in single-dose vial

1. Follow the procedures for the correct handling and disposal of cancer medicines.
2. Use the appropriate aseptic technique for reconstitution and preparation of solutions for administration.
3. Calculate the recommended dose based on the patient's weight to determine the number and strength (20 mg or 30 mg) of vials required.
4. Reconstitute each vial as follows, and if possible, direct the sterile water for injection stream towards the vial walls and not directly at the lyophilized powder:
   1. Vial of 20 mg: Add 2.3 ml of sterile water for injection to obtain enfortumab vedotina 10 mg/ml.
   2. Vial of 30 mg: Add 3.3 ml of sterile water for injection to obtain enfortumab vedotina 10 mg/ml.
5. Gently rotate each vial until the contents are fully dissolved. Allow the reconstituted vials to settle for at least 1 minute, until the bubbles disappear. Do not agitate the vial. Do not expose to direct sunlight.
6. Visually inspect the solution to detect particles in suspension or colour change. The reconstituted solution must be between transparent and slightly opalescent, colourless to light yellow and without visible particles. Discard any vial with visible particles or colour change.

Dilution in infusion bag

1. Remove the calculated dose amount of reconstituted solution from the vials and transfer it to an infusion bag.
2. Dilute enfortumab vedotina with a glucose 50 mg/ml (5%) or sodium chloride 9 mg/ml (0.9%) or lactate Ringer solution. The size of the infusion bag must allow sufficient solvent to achieve a final concentration of between 0.3 mg/ml and 4 mg/ml of enfortumab vedotina.

The solution for administration of enfortumab vedotina diluted is compatible with PVC infusion bags, ethylene-vinyl acetate, polyolefin, such as polypropylene (PP), or PE infusion bags, terephthalate of modified polyethylene glycol and PVC infusion equipment with plasticizer (bis(2-ethylhexyl) phthalate (DEHP) or tris(2-ethylhexyl) trimellitate (TOTM)), PE and with filters (pore size: 0.2-1.2 μm) of polyethersulfone, fluorinated polyvinylidene or mixed cellulose esters.

1. Mix the solution by gently inverting it. Do not agitate the bag. Do not expose to direct sunlight.
2. Visually inspect the infusion bag to detect particles in suspension or colour change before use. The reconstituted solution must be between transparent and slightly opalescent, colourless to light yellow and without visible particles. Do not use the infusion bag if particles in suspension or colour change are observed.
3. Discard any unused solution in the single-dose vials.

Administration

1. Administer the infusion over 30 minutes through a peripheral intravenous line. Do not administer as a rapid or bolus intravenous injection.

No incompatibilities have been observed with closed transfer devices of acrylonitrile butadiene styrene (ABS), acrylic, activated carbon, ethylene propylene diene monomer, ABS methacrylate, polycarbonate, polyisoprene, polyoxymethylene, PP, silicone, stainless steel, thermoplastic elastomer for reconstituted solution.

1. Do not administer other medicinal products simultaneously through the same infusion line.
2. During administration, it is recommended to use in-line filters or syringe filters (pore size: 0.2-1.2 μm, recommended materials: polyethersulfone, fluorinated polyvinylidene or mixed cellulose esters).
