About
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.
Full 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
Patient reported outcomes
To compare patients reported outcomes (PRO) measures per group at month 1 and 3, including:
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.
