Safety, tolerability, and activity of ALV003: results from two phase 1 single, escalating-dose clinical trials.

Background: Celiac disease is the most common hereditary autoimmune disease in humans. The only treatment option for non-refractory celiac disease patients is adherence to a strict life-long gluten-free diet, which often fails to normalize small bowel histology. ALV003 is a mixture of two proteases that degrades gluten and is in clinical development as an oral therapy for patients with celiac disease.

The effects of ALV003 pre-digestion of gluten on immune response and symptoms in celiac disease in vivo.

Effective treatment of celiac disease is an unmet medical need. A glutenase that destroys immunogenic gluten peptides may be clinically valuable. Twenty patients with celiac disease were randomly assigned to ingest a large gluten meal (16 g daily for 3 days) pre-treated with ALV003, a mixture of highly specific glutenases (n=10), or pre-treated with placebo (n=10).
