Spesolimab

What is Spesolimab?[edit | edit source]

Spesolimab (Spevigo) is an interleukin-36 receptor antagonist, is a humanized monoclonal IgG1 antibody (mAb) against human IL-36R produced in Chinese hamster ovary (CHO) cells by recombinant DNA technology.

Spesolimab (Spevigo) is used to treat generalized pustular psoriasis (GPP) flares in adults.

Spesolimab-sbzo is a humanized monoclonal immunoglobulin G1 antibody that inhibits interleukin-36 (IL-36) signaling by specifically binding to the IL36R.
Binding of spesolimab-sbzo to IL36R prevents the subsequent activation of IL36R by cognate ligands (IL-36 α, β and γ) and downstream activation of pro-inflammatory and pro-fibrotic pathways.
The precise mechanism linking reduced IL36R activity and the treatment of flares of GPP is unclear.

This medicine cannot be used in patients with:

severe or life-threatening hypersensitivity to spesolimab-sbzo or to any of the excipients in Spevigo.

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

Recommended dosage:

Administer as a single 900 mg dose by intravenous infusion over 90 minutes.
If flare symptoms persist, may administer an additional intravenous 900 mg dose one week after the initial dose.

Administration:

Your healthcare provider will give you Spevigo through a needle placed in your vein (intravenous infusion) over 90 minutes.

The most common side effects of this medicine include:

Less common, but serious side effects may include:

Spevigo may increase the risk of infections. Do not initiate Spevigo during any clinically important active infection. Instruct patients to seek medical advice if signs or symptoms of clinically important infection occur after treatment with Spevigo.
Evaluate patients for tuberculosis (TB) infection prior to initiating treatment with Spevigo. Do not administer Spevigo to patients with active TB infection.
Hypersensitivity including drug reaction with eosinophilia and systemic symptoms (DRESS) and infusion-related reactions may occur. If a serious hypersensitivity reaction occurs, discontinue Spevigo immediately and initiate appropriate treatment.
Avoid use of live vaccines in patients treated with Spevigo.
It is not known if Spevigo passes into your breast milk. Talk to your healthcare provider about the best way to feed your baby during treatment with Spevigo.

In case of overdose, call the poison control helpline of your country. In the United States, call 1-800-222-1222.

Overdose related information is also available online at poisonhelp.org/help.
In the event that the victim has collapsed, had a seizure, has trouble breathing, or can't be awakened, immediately call emergency services. In the United States, call 911.

The limited data on the use of Spevigo in pregnant women are insufficient to inform a drug-associated risk of adverse pregnancy-related outcomes.
Human IgG is known to cross the placental barrier; therefore, Spevigo may be transmitted from the mother to the developing fetus.
It is not known if Spevigo can harm your unborn baby.

The safety and effectiveness of Spevigo in pediatric patients have not been established.
