ℹ️ 1. What TEPEZZA is and what it is used for

TEPEZZA contains teprotumumab, a type of protein ( monoclonal antibody ).

This medicine is used in adults to treat moderate to severe thyroid eye disease (TED).

TED is an autoimmune condition where the immune system (the body’s natural defences) attacks the muscles and fat around the eyes. A protein called IGF -1R is found in the muscles and fat around the eyes. In people with TED, the immune system activates IGF -1R, causing inflammation and swelling which can push the eyes forward, causing them to bulge. It can also result in double vision, and in severe cases, may cause permanent vision damage.

The active substance in TEPEZZA, teprotumumab, blocks the IGF -1R protein, this keeps the immune system from attacking the muscle and fat tissues around the eyes , which helps reduce swelling, relieve pressure around the eyes and improve disease symptoms.

🩺 Information intended for healthcare professionals only

Posology and method of administration TEPEZZA should be prepared by a healthcare professional using aseptic technique to ensure the sterility of the prepared solution.

Preparation of the medicinal product before administration Step 1: Calculate the dose (mg) and determine the number of vials needed for the 10 or 20 mg/kg dose based on patient weight. Each TEPEZZA vial contains 500 mg of teprotumumab.

Step 2: Using appropriate aseptic technique, reconstitute each vial with 10 mL of water for injection s.

Ensure that the stream of diluent is not directed onto the lyophili sed powder, which has a cake -like appearance. Do not shake, but gently swirl the solution by rotating the vial until the lyophili sed powder is dissolved. The reconstituted solution has a total volume of 10.5 mL. Withdraw 10.5 mL of reconstituted solution to obtain 500 mg. After reconstitution, the final concentration is 47.6 mg/m L.

Step 3: The reconstituted solution must be further diluted in sodium chloride 9 mg/m L (0.9%) solution for infusion, prior to infusion. To prepare the diluted solution, use 100 mL infusion bags for a dose less than 1 800 mg, and 250 mL infusion bags for a dose equal of greater than 1 800 mg. To maintain a constant volume in the infusion bag, a sterile syringe and needle should be used to remove the volume equivalent to the amount of the reconstituted solution to be placed into the infusion bag. The volume of sodium chloride 9 mg/m L (0.9%) solution withdrawn must be discarded .

Step 4: Withdraw the required volume from the reconstituted vial(s) based on the patient’s weight (in kg) and transfer into an intravenous bag containing sodium chloride 9 mg/m L (0.9%) solution for infusion . Mix the diluted solution by gentle inversion. Do not shake. If refrigerated prior to administration, allow the diluted solution to reach room temperature prior to infusion . Care should be taken to ensure the sterility of the prepared solution.

No incompatibilities between teprotumumab and polyethylene (PE), polyvinyl chloride (PVC), polyurethane (PUR) or polyolefin (PO) bags and intravenous administration sets have been observed.

Appearance on reconstitution After reconstitution, TEPEZZA is a nearly colourless or slightly brown, clear to opalescent solution which is free of foreign particulate matter. The reconstituted solution should be inspected for particular matter and discolo uration prior to administration. Discard the solution if particulate matter is present or discolo uration is observed.

Storage of reconstituted and diluted infusion solution Chemical and physical in -use stability of the reconstituted solution in the vial has been demonstrated for up to 4 hours at room temperature (20°C – 25°C) or up to 48 hours at 2°C to 8°C storage condition.

Chemical and physical in -use stability of the diluted solution in the infusion bag has been demonstrated for 24 hours at 2°C to 8ºC followed by 24 hours at room temperature (20°C – 25°C) storage condition.

From a microbiological point of view, the product should be used immediately. If not used immediately, in -use storage times and conditions prior to use are the responsibility of the user and would normally not be longer than 24 hours at 2°C to 8°C, unless reconstitution and dilution has taken place in controlled and validated aseptic conditions. If refrigerated prior to administration, the diluted solution should be at room temperature prior to infusion.

Method of a dministration

  • This medicinal product must be administered as an intravenous infusion. It must not be administered as an intravenous push or bolus.
  • Prior to infusion:
