Trefoil Therapeutics announced it will collaborate with NCATS to complete the investigational new drug enabling activities for their lead compound, TTHX1114, toward a treatment for Fuchs endothelial corneal dystrophy (FECD). Approximately 70,000 people suffer from FECD, which can lead to severe vision loss and for which there currently is no FDA-approved pharmaceutical therapy. Trefoil is developing TTHX1114 as potentially the first medical therapy for treatment of FECD, which is the most common driver of corneal transplantation.
