An expanded clinical trial that tested a groundbreaking, experimental stem cell treatment for blinding cornea injuries found the treatment was feasible and safe in 14 patients who were treated and followed for 18 months, and there was a high proportion of complete or partial success. The results of this new phase 1/2 trial are published in Nature Communications.

The treatment, called cultivated autologous limbal epithelial cells (CALEC), was developed at Mass Eye and Ear, a member of the Mass General Brigham healthcare system. The innovative procedure consists of removing stem cells from a healthy eye with a biopsy, expanding them into a cellular tissue graft in a novel manufacturing process that takes two to three weeks, and then surgically transplanting the graft into the eye with a damaged cornea.
