Summary

This study tests whether omega-3 fatty acid supplements from fish oil, combined with a healthy diet, can reduce disease activity in adults with dermatomyositis, a rare autoimmune disease causing muscle weakness and skin rashes. About 300 participants will take either fish oil capsules or a placebo for 6 months, with regular check-ins and dietary coaching. The goal is to see if this simple supplement can improve symptoms and quality of life.

omega-3 fatty acids from fish oil

What this could lead to

If it works, this could point toward a simple dietary supplement to help manage dermatomyositis symptoms and reduce disease activity.

What could go wrong

This is an early phase 2 trial with only 300 participants, so results may not apply to everyone. The supplement may show no benefit over placebo, and dietary changes can be hard to maintain.
