Press release: Dr. Falk Pharma and Zedira announce completion of phase 1b clinical trial of ZED1227 for the treatment of celiac disease and move on to proof of concept study



Freiburg and Darmstadt, May, 2nd 2017

Dr. Falk Pharma GmbH and Zedira announce the completion of a phase 1b multiple ascending dose clinical trial of ZED1227, a direct acting inhibitor of tissue transglutaminase. The clinical trial confirmed safety and tolerability of ZED1227 in female and male healthy volunteers, meeting the study objectives. In an earlier phase 1a clinical trial safety and tolerability have already been shown for a single ascending dose regimen. Dr. Falk Pharma and Zedira now intend to investigate efficacy of ZED1227 in Celiac Disease patients in a phase 2a clinical trial.

Celiac Disease is the most common chronic inflammation of the small intestine. The autoimmune disease affects about 1% of most populations and is caused by alimentary gluten in genetically susceptible individuals. A key step in celiac disease pathogenesis is gluten-deamidation catalyzed by the patient’s own tissue transglutaminase in the gut. The small molecule ZED1227 targets the dysregulated transglutaminase within the small intestine in order to dampen the immune response to gluten which drives the disease process. Blocking tissue transglutaminase has the potential to offer patients additional safety when applied in support of a ‘mostly’ gluten-free diet thereby improving the quality-of-life of millions of people.

Already in 2011, Dr. Falk Pharma licensed the rights for ZED1227 in Europe and took charge of preclinical and clinical development of the new chemical entity. The license agreement secured Zedira an upfront payment and further milestone payments as well as royalties. The rights outside Europe are jointly owned by the partners.
The project received additional support through a grant from the German Ministry for Education and Research within the Ci3 leading-edge cluster “Ci3-Cluster for Individualized Immune Intervention” in cooperation with Prof. Detlef Schuppan, (University of Mainz).
