Current Secondary Outcome Measures  ICMJE
 (submitted: January 14, 2019)
  • Secondary endpoint/clinical performance by TBUT test [ Time Frame: between Day 1 and Day 35 ±4 and Day 1 and Day 84 ±7 ]
    The between-group comparisons of the average variation of the time obtained at the tear break up time test (TBUT). This full procedure will be performed 3 times per eye and per time point. Each obtained time will be recorded by the investigator in the eCRF. At screening and at baseline visits, the sum of these 3 times for at least one eye to be eligible must be ≤ 30 seconds. Conventionally TBUT's measures shorter than 10 seconds can be referred to tear film instability and measures shorter than 5 seconds, usually, are undoubtable sign of dry eye. The longer it takes, the more stable the tear film. A short TBUT is a sign of poor tear film. A positive number change from baseline indicates an increase in TBUT (improvement) and a negative number change from baseline indicates a decrease in TBUT (worsening).
  • Secondary endpoint/patient reported outcome by DEQS questionnaire [ Time Frame: between Day 1 and Day 35 ±4 and Day 1 and Day 84 ±7 ]
    The between-group comparisons of the average variation of Dry Eye-Related Quality-of-Life (DEQS) general score. It is a validated 15-item scale divided into 2 subscales related to dry eye symptoms and its influence on daily life: The frequency is scored on a 5-point Likert scale ranging from 0 (no symptom) to 4 (highest frequency). • The degree is scored on a 4-point Likert scale ranging from 1 to 4, a larger number indicates a greater burden. The summary score ranges from 0 to 100, higher score indicates higher disability. .

Max total score: 15
  • Secondary endpoint/clinical performance by Schirmer test [ Time Frame: between [Day 1 and Day 84 ±7] ]
    The between-group comparisons of the average variation of the paper length obtained at the Schirmer Test. The Schirmer test without anesthesia will be here performed to measure the rate of secretion of tears produced by the study eye over 5 minutes.The cut-off value for a severe dry eye in the first one is 6 mm. But the cut-off that will here use will be 9 mm with the following interpretation:
    • Normal = ≥ 10 millimeters (mm) of tears,
    • Dry Eye = ≤ 9 mm of tears A positive number change from baseline indicates an increase in tears (improvement) and a negative number change from baseline indicates a decrease in tears (worsening).
  • Secondary endpoint/patient reported outcome by OSDI score [ Time Frame: between [Day 1 and Day 35 ±4] and [Day 1 and Day 84 ±7] ]
    The between-group comparisons of the average variation of Ocular Symptoms Disease Index (OSDI) score. The patient's dry eye symptoms will be assessed with the Ocular Surface Disease Index (OSDI). It is a validated 12-questions scale for patients that covers a broad spectrum of ocular surface symptoms, the severity of such symptoms for patients and how these symptoms affect/impact visual function over a 1-week recall period. Its scores range from 0 to 100, with higher scores indicating greater severity of disease.Positive result is considered when the OSDI score is ≥ 18.To be consistent with the IMD indication, patient with moderate to severe dry eye thus with an OSDI ≥ 18 will be selected. If the patient's OSDI score will be strictly below 18 at the screening or baseline visit, s/he will be considered as a screening failure. Each item response will be collected in the study database since given separately to patients.

Descriptive Information
Brief Title  ICMJE To Demonstrate the Non-inferiority of Eyestil Protection® Compared to Vismed® in Terms of Clinical Performance
Official Title  ICMJE A Prospective Multicenter, Comparative, Randomized, Single-blind, Non-inferiority Study of Eyestil Protection® Unidose Versus Vismed® Unidose in Patients With Moderate to Severe Dry Eye Syndrome
Brief Summary

This is a national, prospective, multicenter, comparative, randomized, single-blinded non-inferiority study performed in two parallel groups.

3 months (plus a run in period of 15 days prior inclusion) Patients with moderate to severe dry eye syndrome.

Detailed Description

Public hospitals and private practices specialized in ophthalmology Approximately 10 sites France Approximately 80 patients globally: 40 per arm with a 1:1 ratio including an expected dropout rate of 15%.

Dry eye has been defined as a multifactorial disease of the ocular surface characterized by a loss of homeostasis of the tear film and accompanied by ocular symptoms, in which the tear film instability and hyperosmolarity, ocular surface inflammation and damage, and neurosensory abnormalities play etiological roles.

However, prevalence estimates for dry eye vary dramatically from 5% to 50% due to the various operational definitions of dry eye used and the characteristics of the population studied.

The available evidence suggests also that dry eye has a negative impact on overall quality of life. It causes pain and irritation and affects ocular and general health and well-being, the perception of visual function and visual performance. Reduced quality of life in everyday activities and leisure pursuits is reported by 60% of patients, while 38% of patients complain of reduced efficiency at work.

Therefore, the economic burden and impact of dry eye on vision and quality of life, work productivity, psychological and physical impact of pain are considerable. As a consequence, dry eye represents a public health burden. However, only a handful of therapies are available for dry eye patient and are used according to the disease severity.

In such context, SIFI SpA. has developed Eyestil Protection® (or SF-104 XNT Single dose). It is a sterile preservative-free device (eye drops) for ophthalmic use containing 0.2% xanthan gum, presented in 0.3 ml unidose containers. The main action of Eyestil Protection is to lubricate and moisturize the ocular surface as well as to protect it from oxidative stress thanks to the anti-oxidative properties of the xanthan gum (as demonstrated by in-vitro studies (Amico, Tornetta et al. 2015). It is indicated in all cases of dry-eye related ocular discomfort and to relief ocular discomfort due to the use of contact lenses.

Eyestil Protection® unidose is CE marked but is not available yet in all European countries, notably in France.

Confronted to a European regulatory change on medical devices - from a Directive (Directive 1993/42/EEC) to a Regulation (MDR 2017/745) that now requires clinical evidence of device performance and safety; SIFI SpA decided to implement the present clinical comparative performance study. The choice of Vismed® (unidose) as the comparator has been done since it is the current French standard of care treatment for patients with moderate to severe dry eyes.

Primary objective

• To demonstrate the non-inferiority of Eyestil Protection® compared to Vismed® in terms of clinical performance as detected by a reduction of keratitis lesions objectified by staining tests after 1 month of treatment, in patients with moderate to severe dry eye syndrome with keratoconjunctivitis.

Secondary objectives Clinical performance

  • To evaluate the tear film stability per group as objectified by the tear break up time (TBUT) test at month 1 and 3;
  • To evaluate the long term clinical performance of Eyestil Protection® compared to Vismed® as detected by a reduction of keratitis lesions objectified by staining tests after 3 months of treatment;
  • To evaluate the tear production per group as objectified by the Schirmer test at month 3.

Patient reported outcomes

  • To compare patients reported outcomes (PRO) measures per group at month 1 and 3, including:

    • Patient's reported symptoms and
    • Patient's quality of life (QoL). Investigator overall satisfaction
  • To assess investigator's overall satisfaction of the treatment's clinical performance at month 1 and 3.

Safety • To describe the safety profile of Eyestil Protection® compared to Vismed® after 3 months of treatment.

Exploratory objectives

• To compare patient's QoL subscale scores per group at each time point.
