PMCF Study to Evaluate Performance and Safety of "Xanoftal Next"

Interventional, Non-comparative, Single-center PMCF Study to Evaluate Performance and Safety of "Xanoftal Next" Used to Attenuate Symptoms of Seasonal Allergic Conjunctivitis, Even When Associated With Dry Eye Syndrome

Dry eye disease (DED), also called keratoconjunctivitis sicca, is a multifactorial disease of the ocular surface characterized by loss of homeostasis of the tear film and accompanied by symptoms such as ocular discomfort and visual disturbance. Patients with moderate-to-severe DED may experience a reduced quality of life due to ocular pain, difficulty in performing daily activities, and depression.

Traditionally, dry eye syndrome and allergic conjunctivitis are regarded as 2 different diseases. However, recent literature has shown both conditions share similar characteristics, including several of their signs and symptoms (e.g. red, itchy, watery, and burning eyes).

On the other hand, red swollen eyelids, burning sensations, ocular irritation, loss of eyelashes and misdirected eyelashes are also common symptoms of Blepharitis, an inflammatory disorder of eyelids affecting all the age and ethnic groups.

First-line therapy for treating dry eye symptoms consists of over the counter (OTC) artificial tear drops, gels, ointments, or lubricants. Manufacturers have developed OTC products that appear to mimic the different layers of the tear film in order to maintain ocular hydration.

For these reasons, an interventional, non-comparative, Post Marketing Clinical Follow-up (PMCF) study was planned to evaluate the performance and safety of "Xanoftal Next" used to attenuate symptoms of seasonal allergic conjunctivitis, even when associated with dry eye syndrome.

The objectives of the PMCF study are confirmation of the performance, collection of additional safety data regarding expected adverse events and detection of potential unexpected adverse events associated with use of "Xanoftal Next" according to the Instructions for Use (IFU).

Each subject, after signing the Informed Consent Form, will enter the screening and baseline phase (the 2 visits will coincide) during which baseline procedures will be completed.

At baseline visit, the "Xanoftal Next" product will be administered to the enrolled subject.

The patient will perform 2 on-site visits: V0 and V2/EOS. To monitor the safety, 1 phone contact is planned (V1) to check for potential adverse events and concomitant medications intake.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Time Frame
Change in Schirmer I test: to evaluate the performance of "Xanoftal Next" to attenuate symptoms of seasonal allergic conjunctivitis, even when associated with dry eye syndrome, through the Schirmer I test	From baseline (V0 = Day 0) to 1 month (EOS/V2 = Day 30 ± 2)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in Tear Break-up Time (TBUT): to evaluate the performance of the "Xanoftal Next" to ensure relief from ophthalmic stress, through the TBUT test		From baseline (V0 = Day 0) to 1 month (EOS/V2 = Day 30 ± 2)
To evaluate the patient satisfaction through a Rensis Likert 5 points patient satisfaction scale	Rensis Likert 5 points patient satisfaction scale Minimum value: Very dissatisfied Maximum value: Very satisfied Higher scores mean a better outcome	End of study visit (EOS/V2 = Day 30 ± 2)
Change in Ocular Surface Disease Index (OSDI): to evaluate the performance of the "Xanoftal Next" to reduce dry eye symptoms, mild to moderate, accompanied by itching, burning, foreign body sensation, redness due intrinsic or extrinsic causes	Ocular Surface Disease Index Minimum value: 0 - none of the time Maximum value: 4 - all of the time Higher scores mean a worse outcome	From baseline (V0 = Day 0) to 1 month (EOS/V2 = Day 30 ± 2)
To evaluate the safety and tolerability of the "Xanoftal Next" through Visual Analogue Scale (VAS) - evaluation of symptoms related to dry eye disease (burning, fatigue, discomfort, redness)	Visual Analogue Scale Minimum value: 0 Maximum value: 10 Higher scores mean a better outcome	End of study visit (EOS/V2 = Day 30 ± 2)
