Official answer


In a head-to-head clinical study between Skyrizi and Humira, researchers found that Skyrizi was better than Humira at clearing moderate-to-severe plaque psoriasis.

  • In this study at 16 weeks, 72% of patients given Skyrizi achieved 90% clearer skin compared to 47% of patients given Humira, a statistically significant outcome.
  • At 16 weeks, 109 patients using Humira who did not achieve 50% to 90% skin clearance were either switched to Skyrizi for a total of 44 weeks or stayed on Humira.
  • In patients who switched to Skyrizi during the study, three times more people achieved 90% clearer skin when compared to Humira. Overall, 66% of those receiving Skyrizi who had formerly used Humira achieved 90% skin clearance at 44 weeks, compared to 21% of those who remained on Humira.
  • There were no new safety concerns in patients who switched from Humira to Skyrizi.

Humira and Skyrizi are both manufactured by AbbVie Inc. of North Chicago, Illinois.

What are Skyrizi and Humira used for and how do they work?

Skyrizi was first approved by the FDA on April 23, 2019 to treat plaque psoriasis in adults. It is also approved to treat psoriatic arthritis, ulcerative colitis and Crohn's disease in adults.

  • Skyrizi works by selectively inhibiting interleukin 23, a cytokine that contributes to inflammation in psoriasis.
  • It is not approved to be used in children.

Humira was initially approved on Dec. 31, 2002 for the treatment of rheumatoid arthritis. In addition to plaque psoriasis, it is also approved to treat other inflammatory conditions in adults such as rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis.

  • Humira is classified as a tumor necrosis factor (TNF) blocker and works by reducing the inflammation linked with these conditions.
  • Humira is also approved to be used in adults and children to treat Crohn's disease, juvenile idiopathic arthritis, ulcerative colitis, uveitis, and a skin condition called hidradenitis suppurativa.

Are both Skyrizi and Humira approved for psoriasis?

Both Skyrizi (risankizumab-rzaa) and Humira (adalimumab) are biologics approved by the FDA to treat adults with moderate-to-severe plaque psoriasis, among other uses. These medicines are used in patients who may benefit from taking injections, pills or phototherapy (treatment using ultraviolet light alone or with pills).

  • Plaque psoriasis is a long-term autoimmune disease in which the cells of your skin are quickly replaced. This causes raised silvery plaques that can be flaky, red, and itchy.
  • In autoimmune diseases the body's immune system starts to mistakenly attack healthy cells and tissues.

Besides psoriasis, the other approved uses that are similar between Skyrizi and Humira are Crohn's disease, ulcerative colitis and psoriatic arthritis. While Skyrizi is approved for use only in adults, Humira can be used in children for Crohn's disease (6 years and older) and ulcerative colitis (5 years and older).
