About this study

Official title: Interventional, Non-comparative, Single-center PMCF Study to Evaluate Performance and Safety of "Cross-Linked Hyaluronic Acid (CLHA)-Based Eyedrops" Used to Improve Lacrimal Abnormalities, Even When Associated With Dry Eye Symptoms

Tear dysfunction, also known as Dry Eye Disease (DED) is frequently encountered in the clinical practice. It is a multifactorial disease of the ocular surface characterized by insufficient tear production, loss of homeostasis of the tear film, increased osmotic stress of the ocular surface, ocular discomfort and visual disturbance.

Hyaluronic acid (HA) is a linear heteropolysaccharide (glycosaminoglycan) with unique hygroscopic, rheological, and lubricating properties. HA is naturally found at the human ocular surface where it contributes to the ocular hydration and lubrication thanks to its capability to bind water molecules.Sodium hyaluronate (SH), the salt form of HA, is widely used in artificial tears to counteract dry eye symptoms by facilitating eyelid sliding and reducing its friction on the corneal-conjunctival surface.

Conventional HA-based eye drops contain linear HA. However, artificially cross-linked HA (CLHA) has several advantages over linear HA in alleviating dry eye symptoms. The increased viscoelasticity of CLHA results in a greater stability and a better resistance to the enzymatic degradation by hyaluronidase, while preserving all the properties of linear HA. Furthermore, chemical cross-linking of HA extends its permanence on the ocular surface, thus reducing the number of instillations and increasing patients' compliance.

For these reasons, an interventional, non-comparative, single-center Post Marketing Clinical Follow-up (PMCF) study was planned to evaluate the performance and safety of "Cross-Linked Hyaluronic Acid (CLHA)-based eyedrops" used as intended to improve lacrimal abnormalities, even when associated with dry eye symptoms.

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 "Cross-Linked Hyaluronic Acid (CLHA)-based eyedrops" according to the Instructions for Use (IFU).

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

At baseline visit (V0), one of the "CLHA-based eyedrops" products 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 being measured

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

  1. Change in Schirmer Test I: to evaluate the performance of the "CLHA-based eyedrops" used to improve lacrimal abnormalities, even when associated with dry eye symptoms due to intrinsic or extrinsic factors, through the Schirmer I test

    Measured: From baseline (V0 = Day 0) to 1 month (EOS/V2 = Day 30 ± 2)

Secondary outcomes (4)
  1. Change in Ocular Surface Disease Index (OSDI): to evaluate the performance of the "CLHA-based eyedrops" used to relieve discomfort to the eyes or ocular mucosa, and eye fatigue caused by intrinsic or extrinsic factors, through OSDI

    Measured: From baseline (V0 = Day 0) to 1 month (EOS/V2 = Day 30 ± 2)

  2. Change in Tear Break-up Time (TBUT): to evaluate the performance of the "CLHA-based eyedrops" used to improve tear film stability in subjects with dry eye symptoms and/or after eye surgery, through the TBUT test

    Measured: From baseline (V0 = Day 0) to 1 month (EOS/V2 = Day 30 ± 2)

  3. The global patient treatment tolerance to the "Cross-Linked Hyaluronic Acid (CLHA)-based eyedrops" as assessed by the Visual Analogue Scale (VAS) as a difference between baseline and Day 30.

    Visual Analogue Scale:

    Minimum value = 0; Maximum value = 10; Higher scores mean a better outcome.

    Measured: End of study visit (EOS/V2 = Day 30 ± 2)

  4. 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

    Measured: End of study visit (EOS/V2 = Day 30 ± 2)

Questions about this trial

What is this clinical trial studying?

A study testing Cross-linked hyaluronic acid eye drops in people with Dry Eye Disease and Dry Eye, run by C.O.C. Farmaceutici S.r.l. at 1 site in Italy.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 27 Mar 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in Schirmer Test I: to evaluate the performance of the "CLHA-based eyedrops" used to improve lacrimal abnormalities, even when associated with dry eye symptoms due to intrinsic or extrinsic factors, through the Schirmer I test (time frame: From baseline (V0 = Day 0) to 1 month (EOS/V2 = Day 30 ± 2)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Mar 2024.
