Blood Based Eyedrops From Different Sources in the Treatment of Severe Keratopathy - A Randomized Clinical Trial

Topical preparations (eye drops) derived from the blood have become a relatively common treatment for more advanced forms of keratopathy. The purpose of this study is to evaluate the effect of two blood components from donors (serum cord blood and serum from adult subject donor peripheral blood) in the treatment of severe keratopathies.

Study Overview

Detailed Description

The rationale for the use of eye drops prepared from the blood as a source is mainly based on their content in growth factors (Growth factors, GF), which play an important role in regulation of many processes involved in normal healing of damaged corneal epithelium . The most used product so far is the eye drop prepared from serum (Autologous Serum, AS) or from platelet-rich plasma (Plasma Rich Platelet, PRP) of peripheral blood taken from the patients themselves. More recently, treatments were introduced by homologous sources that undoubtedly offer advantages as compared to autologous sources. In particular the homologous sources show:

  • not invasiveness to the patient, who could in time not like the repeated withdrawals
  • applicability even in patients with underlying systemic conditions. They may contain in their blood, among others, higher levels of pro-inflammatory factors, with the consequence of poor and inappropriate final product to be prepared and delivered to the eye

    • reliability, since the homologous products can be prepared, controlled, also validated under the microbiological profile and standardized advance, then kept frozen until the dispensation
    • conceptually unlimited availability of the product to be dispensed
    • versatility of therapeutic indications, based on different GF levels which are estimated in advance

The purpose of this study is to evaluate the effect of two products derived from two different blood sources (cord blood collected at birth from placenta umbilical veins and adult subject donor peripheral blood) in the treatment of severe keratopathies.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: CBS eyedrops
Eyedrops prepared from CBS (Cord Blood Serum), and administered 1 drop/each eye/8 times per day, for 30 days
PBS eyedrops (prepared from adult peripheral blood serum) will be provided as frozen vials containing 0.8 ml of the product and will be administered at a regimen of 1 drop / 8 times day / each eye during the waking period, with the last administration to take before bedtime.
Active Comparator: PBS eyedrops
Eyedrops prepared from PBS (Peripheral Blood Serum) from adult donor subjects, administered 1 drop/each eye/8 times per day, for 30 days
CBS eyedrops (prepared from umbilical cord blood serum) will be provided as frozen vials containing 0.8 ml of the product and will be administered at a regimen of 1 drop / 8 times day / each eye during the waking period, with the last administration to take before bedtime.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Variation of corneal epithelium damage
Time Frame: 30 days
The effect of the treatment(s) will be evaluated by measuring the area of damaged corneal epithelium (calculated as the mm2 of damaged epithelium) after treatment as compared to baseline, and defined as 1. complete healing : no detection of damaged area; 2. Partial healing : reduction of the damaged corneal area after treatment as compared to baseline ; 3. No improvement : same damaged corneal epithelial area in mm2 at baseline and after treatment; 4. Worsening : damaged corneal epithelial area in mm2 after treatment larger than at baseline
30 days

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Variation of subjective sensation of discomfort
Time Frame: 30 days
The effect of the treatment(s) will be evaluated by measuring the subjective discomfort (expressed with the OSDI score) after treatment as compared to baseline and defined as 1. Disappearance of discomfort: OSDI score < 6/100; 2. Reduction of discomfort: reduction of the OSDI score after treatment as compared to baseline ; 3. No improvement : same values for OSDI score after treatment as detected in baseline; 4. Worsening : score for OSDI score after treatment higher than that detected at baseline
30 days
