NCT ID NCT04180904
First seen Jun 29, 2026 · Last updated Jun 30, 2026 · Updated 1 time
Summary
This study investigates whether changing diet can reduce disease activity in people with psoriatic arthritis. Participants are randomly assigned to one of two diets: one focusing on which foods are eaten, and another limiting daily calorie intake. The trial lasts 24 weeks and includes adults aged 18–80 with a confirmed diagnosis and moderate-to-high disease activity.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
dietary intervention (food-focused diet vs. calorie-restricted diet)
What this could lead to
If successful, this could show that dietary changes help control psoriatic arthritis symptoms, offering a non-drug way to manage the disease.
What could go wrong
This is a small, early-stage study without a placebo control, so results may not be conclusive. Diet changes can be hard to maintain, and benefits may vary from person to person.
