Is this trial a fit for you?

Likely a good fit

Adults 21 years or older with Fuchs dystrophy or pseudophakic bullous keratopathy who are suitable for surgery and can commit to follow-up visits.

Probably not a fit

Patients with corneal scarring or other anterior segment abnormalities may not benefit and are excluded.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a Phase 1 interventional study evaluating the safety and feasibility of Endo Tek, a graft made of cultivated human corneal endothelial cells attached to a hydrogel substrate. Participants undergo a surgical procedure to receive the HCEC graft and are followed to monitor safety and preliminary signals of effectiveness. The study compares pre- and post-operative visual acuity, corneal thickness, and endothelial cell density to gauge early efficacy. Eligibility includes adults 21 and older with Fuchs dystrophy or pseudophakic bullous keratopathy, among other criteria. The trial is sponsored by OcuCell with Clinica Quesada as a collaborator, at Clinica Quesada in San Salvador.

Why it matters

Potential benefit: If successful, the approach could improve vision and corneal health in patients with endothelial dysfunction.

How similar studies have gone: Early work in similar endothelial cell grafts shows potential safety signals and possible functional gains in endothelial function, but this exact Endo Tek approach is exploratory.
