Overview

Esperoct is a medicine used to treat and prevent bleeding in patients with haemophilia A, an inherited bleeding disorder caused by the lack of a clotting protein known as factor VIII. Esperoct can be used in adults and children from 12 years of age.

Esperoct contains the active substance turoctocog alfa pegol.

Esperoct can only be obtained with a prescription and treatment should be started by a doctor who has experience in the treatment of haemophilia.

Esperoct is given as an injection into a vein. The dose, frequency and duration of treatment depend on whether it is used to treat or prevent bleeding, as well as on the severity of the haemophilia, the extent and location of the bleeding and the patient’s condition and weight. Patients or their carers may be able to inject Esperoct themselves at home once they have been trained appropriately.

For more information about using Esperoct, see the package leaflet or contact your doctor or pharmacist.

Patients with haemophilia A lack factor VIII, a protein needed for normal clotting of the blood, and as a result, they bleed readily. The active substance in Esperoct, turoctocog alfa pegol, works in the body in the same way as human factor VIII. It replaces the missing factor VIII, thereby helping the blood to clot and giving temporary control of the bleeding disorder.

Part of the active substance is a chemical called polyethylene glycol (PEG), which is added to help the medicine remain in the body for longer and thereby prolong its action.

Esperoct has been shown to be effective at preventing and treating bleeding episodes in patients with severe haemophilia who were previously treated with other factor VIII products.

In a study involving patients between 12 and 66 years of age, 175 patients given Esperoct every 4 days or twice weekly as preventive treatment had, on average, around 4 bleeding episodes a year, achieving the target of the study, which was less than 8.5 episodes a year. When bleeding episodes occurred, they were successfully treated with one or two further injections in 94% of cases.

Twelve further patients in this study did not receive preventive treatment but were given Esperoct for treating bleeding ‘on demand’. These patients had on average around 32 bleeding episodes a year and Esperoct was successful at stopping the bleeds 97% of the time after 1 or 2 injections.

In a second study in 68 children aged below 12 years, Esperoct given as preventive treatment reduced the number of bleeding episodes to around 2 episodes a year.

Hypersensitivity (allergic) reactions can occur with Esperoct and are uncommon (affecting up to 1 in 100 people). These include swelling, burning and stinging at the injection site, chills, flushing, itchy rash, headache, hives, low blood pressure, lethargy, nausea and vomiting, restlessness, a rapid heartbeat, tightness of the chest, tingling and wheezing. In some cases these reactions can become severe.

Very rarely, patients may develop antibodies against hamster protein in the medicine and have allergic reactions. Esperoct must not be used in patients with allergy to hamster proteins.

Following treatment with factor VIII products, including Esperoct, some patients may develop inhibitors (antibodies) against factor VIII, causing the medicine to stop working and resulting in a loss of bleeding control. In such cases, a specialised haemophilia centre should be contacted.

For the full list of side effects and restrictions with Esperoct, see the package leaflet.

Studies have found that Esperoct is effective at preventing and treating bleeding in patients with haemophilia A. Because Esperoct is ‘pegylated’, patients on this medicine could also have fewer or less frequent injections than they would on conventional FVIII products. However, part of the active substance in Esperoct (called PEG) may accumulate in the body, including in a structure in the brain called the choroid plexus, following long-term treatment. Since this could potentially cause problems especially in children below 12 years of age, Esperoct is only approved for use in adults and children from 12 years of age.

The European Medicines Agency decided that Esperoct’s benefits are greater than its risks and it can be authorised for use in the EU.
 

The company that markets Esperoct will carry out a study to investigate the potential effects of PEG accumulation in the choroid plexus of the brain and other tissues and organs.

Recommendations and precautions to be followed by healthcare professionals and patients for the safe and effective use of Esperoct have also been included in the summary of product characteristics and the package leaflet.

As for all medicines, data on the use of Esperoct are continuously monitored. Side effects reported with Esperoct are carefully evaluated and any necessary action taken to protect patients.
 

Esperoct received a marketing authorisation valid throughout the EU on 20 June 2019.
