6. Contents of the pack and additional information

Kyntheum contains the active ingredient brodalumab. Brodalumab is a monoclonal antibody, a type of differentiated protein that recognizes and binds to certain proteins in the body.

Brodalumab belongs to a group of medications known as interleukin (IL) inhibitors. This medication blocks the activity of IL-17 proteins, which are present at elevated levels in diseases such as psoriasis.

Kyntheum is used to treat a skin condition called "plaque psoriasis", which causes skin inflammation and the formation of scaly plaques. Kyntheum is indicated for adults with moderate to severe plaque psoriasis affecting extensive areas of the body.

Using Kyntheum will help improve skin clearance and reduce the signs and symptoms of psoriasis, such as itching, redness, scaling, burning, stinging, cracking, flaking, and pain.

Do not use Kyntheum

• If you are allergic to brodalumab or any of the other components of this medication (listed in section6). If you suspect you are allergic, consult your doctor before using Kyntheum.
• If you have active Crohn's disease.
• If you have an infection that your doctor considers important (for example, active tuberculosis).
