LumiThera announced it has completed enrollment in its multicenter US clinical study in non-neovascular (dry) age-related macular degeneration (AMD) patients.

The randomized, multicenter study, LIGHTSITE III, enrolled the last patient at the Byers Eye Institute at Stanford University in Palo Alto, California, with Principal Investigator, Diana Do, MD. 

“We are very pleased to be able to enroll the last subject in the study. Initial efficacy data will be available in approximately 13 months,” Dr. Do said in a company news release.  “The study will continue to follow patients for up to 24 months.”

LIGHTSITE III, using the Valeda Light Delivery System, is a FDA, IDE-approved prospective, randomized, double-masked trial being conducted in ten leading retinal centers throughout the United States. The study enrolled 100 patients suffering from dry AMD and will treat and follow patients over the course of 2 years. In addition to demonstrating safety, key efficacy endpoints include visual acuity, contrast sensitivity, and reduction of drusen deposits.

The National Institute of Health and division of the National Eye Institute provided a $2.5M grant to partially support the U.S. study. 

“It is exciting to be involved in a potential new treatment for dry AMD patients,” said Allen Hu, MD, Principal Investigator, Cumberland Valley Retina Consultants. “Our experience to date in the trial with the Valeda system has been very encouraging.” 

LumiThera obtained a CE mark to commercialize the Valeda Light Delivery System in the European Union for the treatment of ocular damage and disease including dry AMD. The LIGHTSITE II post-marketing study with top retinal centers in key European countries was recently completed with limited enrollment due to COVID-19 and will provide results later this year.

“The data we continue to accumulate from these trials will be used to further support our commercialization efforts and global regulatory submissions,” stated Clark Tedford, PhD, President and CEO. “We enlisted top retinal private and university centers in the U.S. for the LIGHTSITE III trial and if successful, the study should allow an important treatment choice in preventing vision loss for patients in the U.S.”
