Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a multicenter, randomized, open-label, two-arms phase I/II, clinical trial, in which 42 patients will be enrolled with the principal objective to evaluate the efficacy through changes in lesion size and, secondary, to evaluate the safety and efficacy through corneal sensibility, corneal opacity, visual acuity and complications of Neurotrophic Keratopathy (NK). Patients will be randomized 1:1 to receive experimental treatment (cord blood eye drops) or conventional treatment (artificial tears and therapeutic contact lens).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a multicenter, randomized, open-label, two-arms phase I/II, clinical trial, in which 42 patients will be enrolled with the principal objective to evaluate the efficacy through changes in lesion size and, secondary, to evaluate the safety and efficacy through corneal sensibility, corneal opacity, visual acuity and complications of NK. Patients will be randomized 1:1 to receive experimental treatment (cord blood eye drops) or conventional treatment (artificial tears and therapeutic contact lens).

All patients, with conventional or experimental treatment, will be treated for 19 days. A topical antibiotic will be added too as a concomitant treatment to all treatment groups, until the injury closes or according to medical criteria.

After signing informed consent, inclusion and exclusion criteria will be assessed, and if the patient meets all the requirements, the patient will be randomized.

After initiation of the treatment, patients will be follow-up at 2-3 days and once a week for 3 weeks. A final follow-up is planned at 6 weeks.
