Brief Summary:
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).

Neurotrophic Keratopathy Drug: Cord Blood Eye Drops Drug: Conventional treatment Phase 1 Phase 2

Detailed Description:

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.

  3. Stage on the corneal lesion [ Time Frame: at 3 weeks post-treatment ]
    Changes stage on the corneal lesion (cured, stage 1, stage 2, stage 3) from baseline

  4. Qualitative scale of corneal sensibility [ Time Frame: at 2-3 days post-treatment and at 1, 2, 3 and 6 weeks post-treatment ]
    Changes in qualitative scale of corneal sensibility (normoesthesia, hypoesthesia, anesthesia)

  5. Corneal opacity [ Time Frame: at 2-3 days post-treatment and at 1, 2, 3 and 6 weeks post-treatment ]
    Changes on corneal opacity from baseline (not response, improvement, worse)

  6. Visual acuity [ Time Frame: at 2-3 days post-treatment and at 1, 2 and 6 weeks post-treatment ]
    Line variation in relation to visual acuity
