What is Skyrizi used for?
- Skyrizi (risankizumab) is used to treat patients who have moderate or severe plaque psoriasis (raised, silvery flaking of the skin).
- Plaque psoriasis (PP) is an ongoing autoimmune condition, which causes inflammation and increased immune response.
How does Skyrizi work?
- Skyrizi is an immunosuppressant that reduces PP by blocking a small protein called interleukin 23 cytokine (IL23), which is a messenger for inflammation and immune response.
- Once IL23 is blocked the inflammation is decreased and the plaque psoriasis improves.
- Skyrizi is an injection given under the skin (subcutaneous injection) on week 0 and week 4, then after these first two doses it is given every 12 weeks.
- In the clinical trial UltIMMa-12 they looked at how many patients had a 90% reduction in their psoriasis score after 16 weeks of treatment. Skyrizi had the best improvement with a reduction in psoriasis by 75%, Ustekinumab had a reduction of 42% and patients on a placebo injection had only 2% reduction.
What is Skyrizi FDA approved for?
- Skyrizi is approved for adult patients who suffer from moderate to severe plaque psoriasis and whose psoriasis requires treatment with injections, oral medicines or ultraviolet light.
