Spevigo

Spevigo can only be obtained with a prescription and treatment should be started and supervised by a doctor experienced in managing inflammatory skin diseases.

The medicine is given once as an infusion (drip) into a vein over 90 minutes; a second dose can be given one week later if symptoms are still present.

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

The active substance in Spevigo, spesolimab, is a monoclonal antibody (a type of protein) that binds to and blocks the receptor (target) for a protein involved in inflammation called interleukin-36 (IL-36). By preventing IL-36 from attaching to its receptor, Spevigo reduces inflammation and improves the symptoms of generalised pustular psoriasis.

A main study involving 53 adults with generalised pustular psoriasis flare-ups of moderate to severe intensity showed that Spevigo was more effective than placebo (a dummy treatment) at improving symptoms of the disease. After one week, 54% (19 out of 35 patients) of those who received a single dose of Spevigo had no visible pustules compared with 6% (1 out of 18 patients) of those who were given placebo, as measured using the GPPGA pustulation subscore (a measure of the severity of the pustules).

The most common side effects with Spevigo (which may affect more than 1 in 10 people) are infections.

For the full list of side effects of Spevigo, see the package leaflet.

Spevigo must not be given to patients who have an active infection that the doctor considers important or those with severe or life-threatening hypersensitivity (allergy) to any of the medicine’s ingredients.

The severity of generalised pustular psoriasis flare-ups varies but can lead to organ failure and sepsis (blood poisoning). The disease is therefore a considerable burden on patients’ lives. At the time of approval, there were no approved treatments for flare-ups of generalised pustular psoriasis and most therapies used in clinical practice had limited data on safety and efficacy.

Spevigo has been shown to be effective in clearing pustules within one week following a flare-up. Although safety data are limited, the safety profile is considered manageable.

Spevigo has been given ‘conditional authorisation’. This means that that the European Medicines Agency decided that the benefits of Spevigo are greater than its risks, but the company will have to provide additional evidence after authorisation.

Conditional authorisation is granted on the basis of less comprehensive data than are normally required. It is granted for medicines that fulfil an unmet medical need to treat serious diseases and when the benefits of having them available earlier outweigh any risks associated with using the medicines while waiting for further evidence. Every year, the Agency will review any new information that becomes available until data become comprehensive and this overview will be updated as necessary.

Since Spevigo has been given conditional authorisation, the company that markets the medicine will provide data from a study of the medicine in the treatment of recurrent flare-ups in patients with generalised pustular psoriasis to confirm its safety and effectiveness.

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

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

Spevigo received a conditional marketing authorisation valid throughout the EU on 09 December 2022.
