Study summary

To study of a novel, therapeutic Human Cells, Tissues, and Cellular and Tissue-Based Product (HCT/P) in the treatment of severe dry eye disease that is failing conventional treatments. This pilot study will carefully observe and monitor each qualifying and willing individual for response to treatment, signs of toxicity and adverse effects from the treatment, and for ability of the treatment to improve comfort and restore vision.

Read the detailed description

Eligible patients presenting with severe dry eye disease that have failed treatment with conventional measures will be screened for inclusion into the study. The treatment will consist of administration of formulated topical eye drops containing cadaveric epithelial stem cell-derived product. These eye drops will be transplanted by topical self-administration by the patient four times daily in both eyes for a three month interval.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Feb 2019 to primary completion in Apr 2022, 38 months.

Of 199 non-industry interventional studies with no phase under Dry Eye Syndromes, half reached primary completion within 12 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 25. This study's 38 months is above that.

Counting every sponsor, half of 312 studies reached it within 10 months; a quarter within 4 and three quarters within 18.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 21, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
