Spevigo

Generic name: Spesolimab-sbzo
Dosage form: injection, for intravenous use
Drug class: Interleukin inhibitors

Usage of Spevigo

Spevigo (spesolimab-sbzo) is an infusion that may be used to treat generalized pustular psoriasis (GPP) flares in adults. Most people only require a single 900mg dose, although a second dose of 900mg may be given one week after the initial dose if flare symptoms persist.

GPP flares are unpredictable and characterized by red, painful, itchy, pus-filled bumps (called pustules) that often cover large areas of the body. They can appear suddenly or slowly. The condition is rare and life-long and is very different from plaque psoriasis. Skin problems can be accompanied by fever, extreme tiredness, muscle weakness, an increased number of white blood cells, and other signs of inflammation throughout the body.

Spevigo works by blocking the activation of the interleukin-36 receptor (IL-36R), an inflammatory cytokine that is a key part of a signaling pathway within the immune system. Overstimulation or dysregulation of IL-36R is associated with the overproduction of keratinocytes and immune cells and psoriatic-like skin disorders. The exact way Spevigo works to reduce GPP flares is unknown.

Spevigo was FDA approved on September 1, 2022. It was the first treatment specifically for pustular psoriasis to be approved.

How to use Spevigo

Spevigo is administered as an intravenous infusion over 90 minutes by a healthcare provider. Only one dose is usually needed, although a second dose may be given a week later if flares persist.

Your healthcare provider will use an aseptic technique to draw up two vials of Spevigo (each vial contains 450mg/7.5 ml) and dilute it in 85 ml of sodium chloride to make a total volume of 100 ml.

The solution should be administered immediately but can be kept for up to 4 hours if refrigerated at 2°C to 8°C (36°F to 46°F) and protected from light.

Spevigo should not be mixed with other medicinal products.

The total infusion time, including any stop time, should not exceed 180 minutes.

Spevigo may increase your risk of infections. Your healthcare provider should determine that you are free from infections, including tuberculosis (TB) before beginning Spevigo and monitor you for any infections that may develop.

fevers, chills, or sweats

muscle aches

cough

shortness of breath

What other drugs will affect Spevigo

No formal drug interaction studies have been conducted with Spevigo, but because it has effects on the immune system there are likely to be interactions with other immune-suppressing agents, such as infliximab and most vaccines because they require a response from the immune system to vaccination. Some herbal medicines and probiotics may also interact.

Do not administer live vaccines concurrently with Spevigo.

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.
