Seite auf Deutsch targeting transglutaminase 

Zedira is a privately held, clinical stage biopharmaceutical company specialized in transglutaminase. 

Zedira’s drug candidate ZED12271 was the first transglutaminase blocker ever tested in clinical trials.  
The peptidomimetic compound showed proof-of-concept in a phase 2a study in celiac disease patients. In addition, ZED1227 has a placebo-like safety profile. 
For the first time, a transglutaminase is clinically validated as druggable target. 

Zedira conducts several drug discovery programs targeting dysregulated human transglutaminases. The company established a pipeline of small-molecule drug candidates adapted to specific indications. We refer to the Medicine section for comprehensive information.
