Seite auf Deutsch Celiac Disease

Zedira’s lead indication is celiac disease. Celiac disease is the most common chronic inflammation of the small intestine. The autoimmune disease affects up to 2% of most populations and is caused by nutritional gluten in genetically predisposed individuals. A key step in celiac disease pathogenesis is gluten deamidation and immunogenic potentiation catalyzed by the patient’s own tissue transglutaminase in the gut. 

The small molecule ZED12271 targets the dysregulated transglutaminase within the small intestine to prevent the immune response to transglutaminase-modified gluten, which drives the disease process. Blocking tissue transglutaminase has the potential to offer patients additional safety when used in conjunction with a ‘largely’ gluten-free diet, thereby improving the quality of life of millions of people. 

The drug candidate ZED1227 is a “first-in-class” compound, meaning it is the first transglutaminase blocker explored in humans. In 2011, Dr. Falk Pharma licensed the rights for ZED1227 in Europe and took charge of the preclinical and clinical development of the new chemical entity towards a pharmacological agent. In July 2021, Dr. Falk Pharma and Zedira announced the “successful completion of the phase 2a proof of concept study of ZED1227 for the treatment of Celiac Disease". The detailed results of the study are published in the New England Journal of Medicine (https://www.nejm.org/doi/full/10.1056/NEJMoa2032441). The press release for an overview can be found here. In 2022 Takeda Pharmaceuticals entered collaboration and licensing agreement with Zedira and Dr. Falk Pharma (press release).

The proof-of-concept study is of vital importance beyond celiac disease: 
The first-in-class new chemical entity validated TG2 as a druggable target. Now, the spotlight focuses on fibrotic disorders and anticoagulation.
