Brodalumab

What is Brodalumab?

• Brodalumab (Siliq) is a human interleukin-17 receptor A (IL-17RA) antagonist used to treat adults with moderate to severe plaque psoriasis.

What are the uses of this medicine?

This medicine is used to treat adults with moderate to severe plaque psoriasis:

• who may benefit from taking injections or pills (systemic therapy) or phototherapy (ultraviolet light treatment), and
• who have not responded or lost response to other systemic therapy.

How does this medicine work?

• Brodalumab is a human monoclonal IgG2 antibody that selectively binds to human IL-17RA and inhibits its interactions with cytokines IL-17A, IL-17F, IL-17C, IL-17A/F heterodimer, and IL-25.
• IL-17RA is a protein expressed on the cell surface and is a required component of receptor complexes utilized by multiple IL-17 family cytokines.
• Blocking IL-17RA inhibits IL-17 cytokine-induced responses including the release of pro-inflammatory cytokines and chemokines.

Who Should Not Use this medicine ?

• with Crohn’s disease because Siliq may cause worsening of disease.
