COSENTYX is thought to help people with non-radiographic axial spondyloarthritis (nr-axSpA) move and feel better.

Actor portrayal of how COSENTYX works.

What makes COSENTYX different?

COSENTYX is the first FDA-approved biologic of its kind to treat nr-axSpA by targeting a molecule called IL-17A. It's one of the molecules that could play a role in inflammation in people with non-radiographic axial spondyloarthritis. A biologic is a protein-based medication that is made from living sources and taken by injection or infusion.

Why is it important to target and block IL-17A?

Although some IL-17A is normal, when there’s an overproduction of it, your body becomes overwhelmed. This leads to damaging inflammation, causing you to see and feel symptoms of nr-axSpA, like back pain, stiffness, and reduced mobility.

40% improvement in overall symptoms

COSENTYX can help reduce nr-axSpA symptoms so you don't have to fight as hard through your day.

In a clinical trial, many people taking COSENTYX saw at least a 40% improvement in overall symptoms at 16 weeks, with many continuing to see similar results at 1 year.

COSENTYX Experience

COSENTYX has had a consistent safety profile since its launch in 2015, when it was approved to treat adults with moderate to severe plaque psoriasis. In 2016, it was FDA approved to treat active ankylosing spondylitis and active psoriatic arthritis in adults. Then, it was approved in 2020 to treat adults with non-radiographic axial spondyloarthritis. It has since been approved to treat children with plaque psoriasis (6 and older), psoriatic arthritis (2 and older), and enthesitis-related arthritis (4 and older).

COSENTYX is a medicine that affects your immune system. COSENTYX may increase your risk of having serious side effects such as:


COSENTYX may lower the ability of your immune system to fight infections and may increase your risk of infections, sometimes serious.

Inflammatory bowel disease

New cases of inflammatory bowel disease or “flare-ups” can happen with COSENTYX, and can sometimes be serious. If you have inflammatory bowel disease (ulcerative colitis or Crohn’s disease), tell your doctor if you have worsening disease symptoms during treatment with COSENTYX or develop new symptoms of stomach pain or diarrhea.
