Risankizumab, sold under the brand name Skyrizi, is a medication used to treat moderate to severe plaque psoriasis.[1] Other uses may include generalized pustular psoriasis, erythrodermic psoriasis and psoriatic arthritis.[6]

Common side effects include upper respiratory tract infection, headache, tiredness, and pain at the site of injection.[2][3] It also increases the risk of other infections.[3] While there is no evidence of harm in pregnancy, such use has not been well studied.[7] It is a monoclonal antibody that attaches to and blocks interleukin 23A (IL-23A).[2][8]

Risankizumab was approved for medical use in the United States in 2019.[3][2] In the United States it costs about 17,800 USD per dose as of 2021.[9] In the United Kingdom this amount costs the NHS about £3,300.[10]

Medical uses

The efficacy, safety and tolerability was further investigated in a phase III program comprising four clinical trials which compared risankizumab to ustekinumab, adalimumab and placebo in the indication of plaque psoriasis. The results of these trials confirmed the efficacy and tolerability of risankizumab.[11]


It is used as a 150 mg dose.[3] This is given at time zero, after 4 weeks, and than every 12 weeks.[3]


Risankizumab was approved by the U.S. Food and Drug Administration (FDA) for treatment of moderate-to-severe plaque psoriasis in April 2019.[12][13][14]

It was part of a collaboration between Boehringer Ingelheim and AbbVie.

The FDA approved risankizumab based on evidence primarily from five clinical trials (Trial 1/NCT0202684370, Trial 2/NCT02684357, Trial 3/NCT02672852, Trial 4/ NCT02694523 and Trial 5/NCT02054481) of 1606 patients with moderate to severe plaque psoriasis.[12] The trials were conducted in Asia, Canada, Europe, Mexico, South America, and the United States.[12]
