About this study

Official title: A Prospective, Multicentric, Randomized, Non-inferiority, Controlled, Open-label Clinical Investigation to Evaluate the Efficacy and Safety of the Use of Myrialen® Gel vs.Recugel®, Two Eye Gel Products Containing 5% Dexpanthenol, in Patients With Moderate to Severe Dry Eye Syndrome

The prospective, multicentric, randomized, non-inferiority, controlled, open-label clinical investigation will evaluate the efficacy and safety of the use of Myrialen® gel vs.

Recugel®, two eye gel products containing 5% dexpanthenol, in patients with moderate to severe dry eye syndrome.

A total of 110 evaluable patients (55 in each treatment group), ≥18 years of age, will be required for data analysis. A total of 124 patients (62 in each treatment group) will be randomized to replace potential early withdrawals or non-evaluable patients.The primary objective of this investigation is to demonstrate non-inferior efficacy of Test Myrialen® gel over the Reference Recugel® in improving corneal and conjunctival surface state, assessed through slit lamp biomicroscopy examination, in patients with moderate to severe dry eye syndrome.

Read the detailed description

There is scarce documentation in literature on the effects of dexpanthenol in the management of DED. In a randomized, double-blind, placebo-controlled study that evaluated the effect of dexpanthenol-containing artificial tears in 50 patients with dry eyes, patients receiving the active ingredient had significant improvement of disturbances of the corneal epithelial permeability (as measured by fluorophotometry and Schirmer test, Rose Bengal staining, TFBUT), compared to the dexpanthenol-free eyes drops. Despite the scarce literature documentation, the use of 5% dexpanthenol, which stimulates the processes of reparative regeneration and possesses an anti-inflammatory effect, is actually considered as one of the promising directions in the management of patients with DED. Dexpanthenol has also been developed as a component of a contact lens system that controls its release as osmoprotectant and moisturizing agent with the aim to reduce symptoms of ocular dryness.

Based on this background, this investigation has been designed to compare the effects of the investigational device Myrialen® gel with another device containing 5% dexpanthenol, i.e. Recugel® eye gel, in the treatment of patients with moderate to severe dry eye syndrome. In particular, the main objective of this investigation is to demonstrate that the test device Myrialen®gel will be non-inferior to the reference device Recugel® in improving corneal and conjunctival surface state.

What is being measured

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

  1. Efficacy assessment through National Eye Institute (NEI) total score compared to baseline

    The NEI/Industry Workshop guidelines will be used as grading scale of the corneal and conjunctiva damage used. The cornea will be divided into five sectors (central, superior, inferior, nasal and temporal), each of which will be scored on a scale of 0-3, with a maximal score of 15. Both nasally and temporally, the conjunctiva will be divided into a superior paralimbal area, an inferior paralimbal area and a peripheral area with a grading scale of 0-3 and with a maximal score of 9 for the nasal and temporal conjunctiva.

    Measured: Day 30

Secondary outcomes (9)
  1. Efficacy assessment through National Eye Institute (NEI) total score compared to baseline

    The NEI/Industry Workshop guidelines will be used as grading scale of the corneal and conjunctiva damage used. The cornea will be divided into five sectors (central, superior, inferior, nasal and temporal), each of which will be scored on a scale of 0-3, with a maximal score of 15. Both nasally and temporally, the conjunctiva will be divided into a superior paralimbal area, an inferior paralimbal area and a peripheral area with a grading scale of 0-3 and with a maximal score of 9 for the nasal and temporal conjunctiva.

    Measured: Day 7

  2. Efficacy assessment through National Eye Institute (NEI) corneal score compared to baseline

    The NEI/Industry Workshop guidelines will be used as grading scale of the corneal and conjunctiva damage used. The cornea will be divided into five sectors (central, superior, inferior, nasal and temporal), each of which will be scored on a scale of 0-3, with a maximal score of 15.

    Measured: Day 7 and Day 30

  3. Efficacy assessment through National Eye Institute (NEI) conjunctival score compared to baseline

    The NEI/Industry Workshop guidelines will be used as grading scale of the corneal and conjunctiva damage used. . Both nasally and temporally, the conjunctiva will be divided into a superior paralimbal area, an inferior paralimbal area and a peripheral area with a grading scale of 0-3 and with a maximal score of 9 for the nasal and temporal conjunctiva.

    Measured: Day 7 and Day 30

  4. Assessment of Changes in impact of Dry Eye on Everyday living (IDEEL) questionnaire (symptom-bother and impact on daily life modules) from baseline

    The IDEEL is divided into different sectionsa and only two will be considered in patient evaluation. The "Dry Eye Symptom-Bother" module includes 20 items: Item 1 from 0 "none of the time" to 4 "all of the time"; Items 2-from 1 "not at all" to 4 "very much". Score 0="I did not have this symptom / Not applicable"; and the "Dry Eye Impact on Daily Life" module composed of 3 sections: dry eye on daily living activities (9 items), emotional impact (12 items) and impact on work (6 items).Items 1-9 are scored on a 5-point Likert-like scale from 1 "all of the time" to 5 "none of the time". Items 10-21, 23-27 are scored on a 5-point Likert-like scale from 0 "all of the time" to 4 "none of the time". Item 22 is scored on a dichotomous scale: 1 "Yes", 0 "No". This item is not included in the calculation of the scores.

    Measured: Day 30

  5. Assessment of Changes in Tear-Film Break-Up Time from baseline

    The tear film is observed under cobalt-blue filtered light of the slit lamp biomicroscope and the time that elapses between the last blink and appearance of the first break in the tear film is recorded with a stopwatch (a break is seen as a dark spot in a sea of blue). TFBUT results of less than 10 seconds are consistent with dry eyes.

    The TFBUT will be measured twice during the first minute after the instillation of the fluorescein.

    If the 2 readings differ by more than 2 seconds a third reading will be taken. The TFBUT value will be the average of the 2 or 3 measurements.

    Measured: Day 7 and Day 30

  6. Assessment of quantitative normalization of the tear film from baseline

    Change in Schirmer's Test values from baseline. The Schirmer's test measures the quantity of total tear secretion, including reflex and basal tears, produced by the eye. A 35 mm x 5 mm size filter paper strip is used to measure the amount of tears that are produced over a period of 5 minutes. The wet portion of the strip is measured in millimeters. The test is done under ambient light. The patient is instructed to look forward and to blink normally during the course of the test. Normal mean test values range from 8 mm to 33 mm, but an accepted normal value is greater than 10 mm. Patients with dry eyes have wetting values of less than 5 mm in 5 minutes.

    Measured: Day 7 and Day 30

  7. Assessment of qualitative normalization of the tear film from baseline

    Changes will be evaluated through the tear meniscus height. The tear (lacrimal) meniscus examination is conducted using slit-lamp biomicroscopy (narrow slit and low intensity light) and observing the tear (lacrimal) meniscus height. Values are considered normal if within the 0.3 to 0.5-mm range.

    Measured: Day 30

  8. Assessment of changes in visual acuity from baseline

    Visual function will be assessed by distance visual acuity measurement. Both uncorrected distance visual acuity (UNVA, vision with no extraocular optical correction) and best corrected distance visual acuity (BCVA, defined as obtained with the best possible refractive correction) will be measured using the Snellen chart. Visual acuity values will be expressed in decimal, fraction or logMAR. All assessments will be performed using standard charts and procedures at specified visual angle, illumination and contrast. Current refraction will be determined prior to visual acuity testing to obtain best-corrected vision

    Measured: Day 30

  9. Assessment of incidence of treatment-emergent adverse events

    Safety and tolerabiltiy will be assessed through the analysis of Incidence and nature of treatment-emergent adverse events (TEAEs), treatment-emergent serious adverse events (SAEs); Incidence and nature of Adverse Device Effects (ADEs) and serious ADEs (SADEs) during the entire investigation duration; Incidence and nature of Investigational Medical Device Deficiencies (IMDDs) during the entire investigation duration.

    Measured: Day 30
