1. What Hepcludex is and what it is used for
What Hepcludex is

Hepcludex contains the active substance bulevirtide, which is an antiviral medicine.

What Hepcludex is used for

Hepcludex is used to treat long-term (chronic) hepatitis delta virus (HDV) infection in adults with compensated liver disease (when the liver is still working well enough). Infection with hepatitis delta virus causes inflammation of the liver.

How Hepcludex works

HDV uses a particular protein in liver cells to enter the cells. Bulevirtide, the active substance in this medicine blocks the protein and so prevents the HDV from getting into liver cells. This reduces the spread of HDV in the liver and reduces inflammation.

2. What you need to know before you take Hepcludex
Do not take Hepcludex:
  • if you are allergic to bulevirtide or any of the other ingredients of this medicine (listed in section 6).

If you are not sure, speak to your doctor before taking this medicine.

Warnings and precautions

Do not stop your treatment with Hepcludex unless your doctor advises you to do so. Stopping the treatment can reactivate the infection and worsen your disease.

Talk to your doctor or pharmacist before taking Hepcludex:

  • if your liver is not working well enough – it is not known how well Hepcludex works in these circumstances; if your liver is not functioning well, taking Hepcludex is not recommended.
  • if you have had kidney disease or if tests have shown problems with your kidneys. Before and during treatment, your doctor may order blood tests to check how well your kidneys are working;
  • if you have HIV infection or hepatitis C - it is not known how well Hepcludex works in these circumstances; your doctor may order blood tests to check the status of your HIV or hepatitis C infection

Abdomen

Upper thighs

1A Storage

Bulevirtide vials must be stored in the original packaging in the refrigerator (2–8 °C) in order to protect bulevirtide from light.

1B Preparing doses

The following instructions are for dissolving a single dose.

1C Wash hands

Wash your hands well using soap and warm water and dry them with a clean towel.

Once your hands are clean, do not touch anything else other than the medicine, supplies and the area around the injection site.

1D Clean vial

Wipe the vial top with a new alcohol pad and let the top air-dry.

If you touch the rubber top after cleaning it, clean it again with a new alcohol pad.

2A Draw up sterile water

Pick up the syringe. Put the longer needle on.

Important! Be sure the capped needle is tight by pushing it down slightly while twisting it clockwise.

Pull off the plastic cap.

Open the sterile water for injection. Insert the needle in the vial and gently turn the water vial upside down. Make sure the tip of the needle is always below the surface of the water to help keep air bubbles from entering the syringe.

Slowly pull the plunger back to get 1.0 ml of sterile water into the syringe. Carefully remove the needle and syringe from the vial.

2B Inject sterile water into the powder

Gently tap the bulevirtide vial to loosen the powder.

Insert the needle with sterile water into the bulevirtide vial at an angle.

Inject the sterile water slowly, so it can drip down the side of the vial into the bulevirtide powder.

2C Gently mix bulevirtide

Gently tap the bulevirtide vial with your fingertip for 10 sec to start dissolving the powder. Then gently roll the bulevirtide vial between your hands to ensure thorough mixing. Make sure no bulevirtide powder is stuck to the vial wall.

Important! Do not shake the bulevirtide vial. Shaking will make the medicine foam and it will take much longer to dissolve.

2D Inspect bulevirtide

Once the powder starts to dissolve, just set it aside and it completely will dissolve.

After tapping, it could take up to 3 min to dissolve.

2E Bulevirtide ready for injection

When mixed completely, Clean the bulevirtide the bulevirtide solution should be clear.

Important! Completely dissolved bulevirtide should be clear and without foam.

If the bulevirtide solution appears foamy or yellowish, allow more time for it to dissolve.

If you see bubbles, gently tap the vial until they disappear.

If you see any particles in the bulevirtide solution once it is (completely) dissolved, do not use that vial. Contact your doctor or pharmacist that provided it.

Reconstituted bulevirtide must be used immediately.

2F Clean vial

Clean the bulevirtide vial top again, using a new alcohol pad.

Allow it to air dry.

3A Insert needle into vial

Pick up the syringe.

Insert the needle into the vial of liquid bulevirtide.

3B Draw up bulevirtide

Gently turn the vial upside down. Make sure the tip of the needle is always below the surface of the bulevirtide solution to help keep air bubbles from entering the syringe. Slowly pull the plunger to get 1.0 ml of bulevirtide.

3C Finishing preparation

Gently tap or flick the syringe and push/pull the plunger to remove extra air and bubbles.

To be sure you end up with 1.0 ml of bulevirtide in the syringe, you may need to pull the plunger past the 1.0 ml mark.

Carefully remove the needle and syringe from the vial.

3D Change and discard the needle

Remove the longer needle from the syringe and dispose of it properly so that nobody can be injured.

Important! Do not put the plastic cap back on the needle.

3E Attach needle for injection

Place the shorter needle on the syringe.

Important! Be sure the capped needle is tight by pushing it down slightly while twisting it clockwise.

Pull off the plastic cap.

3F Choose the injection site

Choose a site different from the one you used for your last injection. Clean the injection site with a new alcohol pad. Start in the centre, apply pressure and clean in a circular motion, working outward.

Important! Allow site to air-dry.

3G Prepare injection site

Pinch and hold a fold of skin around the injection site.

3H Inject bulevirtide
