Promising Drugs For Psoriasis

Two new drugs show promise in treating psoriasis, a long-term skin condition that can cause itching, flaking and pain. About 3 of every 100 people in the United States have psoriasis. Both studies used molecules that block a protein called IL-17. This protein helps to cause skin inflammation. It is found at high levels in the blood of people with psoriasis. One study involved 198 people. All had moderate to severe psoriasis. They were randomly divided into groups. Some groups got injections of a drug called brodalumab, which blocks the action of IL-17. Others got placebo injections. After 16 weeks, the drug dramatically reduced symptoms. In some cases, no signs of psoriasis existed. The second study involved 142 people with moderate to severe psoriasis. They received either six injections of a drug called ixekizumab, or placebo injections.
