About this study

Official title: A Multicenter, Randomized, Open-label, Two-arms Phase I/II Clinical Trial to Asses Efficacy and Safety of Cord Blood Eye Drops in Neurotrophic Keratopathy

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).

Read the 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.

Being tested
Cord Blood Eye Drops, Conventional treatment

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Corneal lesion size

    Variation percentage in corneal lesion size

    Measured: after 3 weeks post-treatment,

Secondary outcomes (7)
  1. Incidence of Adverse Events

    Safety evaluation through laboratory data and adverse events

    Measured: From date of randomization until the date of the last visit (6 weeks post-treatment)

  2. Corneal lesion size

    Variation percentage in corneal lesion size

    Measured: at 2-3 days post-treatment and at 1, 2 and 6 weeks post-treatment

  3. Stage on the corneal lesion

    Changes stage on the corneal lesion (cured, stage 1, stage 2, stage 3) from baseline

    Measured: at 3 weeks post-treatment

  4. Qualitative scale of corneal sensibility

    Changes in qualitative scale of corneal sensibility (normoesthesia, hypoesthesia, anesthesia)

    Measured: at 2-3 days post-treatment and at 1, 2, 3 and 6 weeks post-treatment

  5. Corneal opacity

    Changes on corneal opacity from baseline (not response, improvement, worse)

    Measured: at 2-3 days post-treatment and at 1, 2, 3 and 6 weeks post-treatment

  6. Visual acuity

    Line variation in relation to visual acuity

    Measured: at 2-3 days post-treatment and at 1, 2 and 6 weeks post-treatment

  7. Neurotrophic keratopathy

    Number of neurotrophic keratopathy complications

    Measured: From date of randomization until the date of the last visit (6 weeks post-treatment)

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Cord Blood Eye Drops and Conventional treatment in people with Neurotrophic Keratopathy, run by Banc de Sang i Teixits at 10 sites in Spain.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 27 Oct 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 sites in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: Low recruitment. No safety issue associated.). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Corneal lesion size (time frame: after 3 weeks post-treatment,). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03084861, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Oct 2020.
