Using cultured oral mucosa to treat severe eye conditions
Cultured Autologous Oral Mucosa Epithelial Sheet for the Treatment of Bilateral Limbal Stem Cell Deficiency FEMJA for " Feuillet Epithélial de Muqueuse Jugale Autologue "
This study is testing whether using skin cells from the inside of the mouth can help people with severe eye conditions regain their vision and improve their quality of life.

What this trial studies
This clinical trial investigates the use of cultured autologous oral mucosa epithelial sheets to treat patients suffering from total bilateral limbal stem cell deficiency, a condition that can lead to blindness. The approach aims to provide a new treatment option for patients who have lost their corneal epithelial stem cells due to severe ocular burns or other rare ocular pathologies. The trial will assess the safety and efficacy of FEMJA transplantation in restoring vision and improving quality of life for affected individuals. Participants will be closely monitored for outcomes related to vision restoration and overall ocular health.
Who should consider this trial
Good fit: Ideal candidates are adults aged 18 and older with total bilateral limbal stem cell deficiency caused by severe ocular burns or other related conditions.
Not a fit: Patients with strictly unilateral ocular afflictions or those with active eye inflammation will not benefit from this study.
Why it matters
Potential benefit: If successful, this treatment could restore vision and significantly improve the quality of life for patients with total bilateral limbal stem cell deficiency.
How similar studies have performed: While this approach is novel and has not been widely tested, it addresses a significant unmet need in treating a rare condition with limited existing options.
