new injectable biologic for moderate to severe plaque psoriasis called Stelara (stel-AR-a)

You'll soon hear about a new injectable biologic for moderate to severe plaque psoriasis called Stelara (stel-AR-a).

It's the first of a new class. It inhibits the inflammatory proteins interleukin-12 and -23...instead of tumor necrosis factor.

Some evidence suggests that Stelara might be more effective than Enbrel for psoriasis. But this isn't proven yet...and there are concerns about long-term safety.
