Research + Clinical Trials


A Phase 2b, Randomized, Double-Blind, Placebo-Controlled, Parallel-Group Study to Evaluate the Efficacy and Safety of PRV‑015 in Adult Patients with Non-Responsive Celiac Disease as an Adjunct to a Gluten-free Diet

The purpose of this study is to learn about the safety and effectiveness of an investigational study drug called PRV-015.

PRV 015 is an antibody designed to block an immune system protein called interleukin-15 (IL 15). IL 15 is made in the small intestine and is one trigger that causes intestinal inflammation followed by death of the intestinal cells. This immune response can be caused by eating gluten. In previous studies, PRV 015 has been shown to reduce inflammation in the intestine and improve the symptoms of celiac disease when used together with a GFD.
