This study tests a new cream made with tiny nanoparticles of the drug apremilast for people with mild to moderate plaque psoriasis. Thirty-six adults will apply the cream twice daily for 12 weeks, and researchers will compare it to a standard steroid cream and a combination of bo…

This phase 4 trial will test the drug apremilast in 425 adults with moderate-to-severe psoriasis. Over 32 weeks, researchers will measure how well the drug clears skin patches and monitor for side effects. The goal is to confirm apremilast's effectiveness and safety in a real-wor…

This study tests a new treatment using CD19 CAR T-cells for people with severe autoimmune diseases that haven't improved with standard therapies. About 30 participants will receive a single dose of these engineered immune cells after chemotherapy. The goal is to see if it's safe …

This phase 2 trial tests an oral drug called HSK44459 for adults with moderate to severe plaque psoriasis. About 150 participants will receive either the drug or a placebo for 16 weeks. The main goal is to see if the drug can reduce psoriasis skin symptoms by at least 75%.

This study will measure a protein called IL-41 in the blood of 90 people with ankylosing spondylitis or psoriatic arthritis, plus healthy volunteers. Researchers want to see if higher levels of this protein are linked to more active disease. The goal is to find a simple blood tes…

This study looks at whether changing how much salt you eat can affect skin sodium levels and the severity of eczema or psoriasis. Fifty adults will follow a low-salt diet and take either sodium tablets or a placebo for several weeks. The goal is to see if this approach is practic…

This study tests a tiny microdevice, about the size of a grain of rice, that holds up to 20 different FDA-approved skin medications. Placed directly on the skin, it releases very small amounts of each drug to see how the skin reacts. The goal is to find out if this device can saf…

This study explores whether short, AI-generated videos from a virtual doctor can help people with psoriasis stick to their topical medication routine. Fifteen adults will be split into three groups: weekly AI videos, weekly human doctor videos, or standard care (one follow-up vis…
