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

Start date: December 2, 2022
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT05825599 Completed - Dry Eye Clinical Trials

PMCF Study to Evaluate Performance and Safety of "HPMC-based Eyedrops" Used to Relieve Dry Eye Symptoms

Start date: September 6, 2022
Phase: N/A
Study type: Interventional

Dry eye disease (DED), also called keratoconjunctivitis sicca, is a common ocular condition characterized by a loss of homeostasis of the tear film and inflammation of the ocular surface. Over the counter (OTC) artificial tears are typically the first line of dry eye treatment; they are meant to supplement the tears that cover the eye's surface. OTC products mimic the different layers of the tear film in order to maintain ocular hydration. Hydroxypropyl methylcellulose (HPMC or hypromellose) is a synthetic modification of the natural polymer, cellulose. It has been widely used in in ophthalmologic formulations such as eye drops and gels due to its solubility in water, biocompatibility, transparency and rheological properties. Eye drops containing HPMC are conventionally used to treat tear film disturbances including dry eye symptoms. 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 "Hydroxypropyl methylcellulose (HPMC)-based eyedrops" used as intended to relieve 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 "HPMC-based eyedrops" according to the Instructions for Use (IFU). "HPMC-based eyedrops" medical devices are ophthalmic solutions containing hydroxypropyl methylcellulose (HPMC) as key ingredient, a polymer able to relief eye discomfort thanks to its moisturizing, lubricating and muco-mimetic properties. HPMC can stabilize the tear film on the ocular surface by creating a protective, transparent and viscoelastic shield. 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), only one of the below reported "HPMC-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.

NCT ID: NCT05825586 Completed - Dry Eye Clinical Trials

PMCF Study to Evaluate Performance and Safety of "Distilled Waters-based Eyedrops" Used to Relieve Dry Eye Symptoms

Start date: August 2, 2022
Phase: N/A
Study type: Interventional

Dry eye disease (DED), also called keratoconjunctivitis sicca, is a common ocular condition characterized by a loss of homeostasis of the tear film and inflammation of the ocular surface. The typical symptoms of DED include irritation, discomfort, blurred or fluctuating vision. Over the counter (OTC) artificial tears are typically the first line of dry eye treatment; they are meant to supplement the tears that cover the eye's surface. OTC products mimic the different layers of the tear film in order to maintain ocular hydration. Distilled waters of natural herbs such as Green Tea, Calendula, Chamomile, Hamamelis and Euphrasia are known for their soothing and refreshing properties. Thanks to the combined action of these natural elements, distilled waters-based eyedrops are particularly indicated to relieve eye dryness, irritation and redness of the eyes' mucosa caused by atmospheric agents, environmental factors, and/or use of contact lenses. "Distilled waters-based eyedrops" medical devices are ophthalmic solutions containing distilled waters able to relieve eye discomfort thanks to their soothing and refreshing action. 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 "Distilled waters-based eyedrops" used as intended to relieve 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 "Distilled waters-based eyedrops" according to the 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 (V0), one of the "Distilled waters-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. The first administration and the intervals at which the treatment should be repeated, to be done as per Investigator judgment and according to the IFU, depend on various factors regarding the physiology of the patients (e.g. type of eye-tear film, anatomy, age), their lifestyle (e.g. use of computer, wearing of contact lenses).

NCT ID: NCT05825352 Completed - Dry Eye Clinical Trials

PMCF Study to Evaluate Performance and Safety of "Ocular Drops Based Upon Carmellose" Used to Relieve Dry Eye Symptoms

Start date: March 24, 2022
Phase: N/A
Study type: Interventional

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. Tear Film & Ocular Surface Society Dry Eye Workshop (TFOS DEWS) II recommends individualized management of DED based on the relative contribution of aqueous deficient and evaporative pathophysiology (to the extent that this can be determined), as well as disease severity. First-line for treating dry eye consists of over the counter (OTC) artificial tear drops, gels, ointments, or lubricants. Carboxymethyl cellulose (CMC) is one of the most common viscous polymers used in artificial tears to achieve prolonged residence time on the ocular surface. 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 "Ocular drops based upon carmellose" used as intended to relieve 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 "Ocular drops based upon carmellose" according 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 (V0), one of the "Ocular drops based upon carmellose" products can be dispensed to the enrolled subject, depending on Investigator clinical evaluation and decision. 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. The first administration and the intervals at which the treatment should be repeated, to be done as per Investigator judgment and according the IFU, depend on various factors regarding the physiology of the patients (e.g. type of eye-tear film, anatomy, age), their lifestyle (e.g. use of computer, wearing of contact lenses) and their eye-surgery history (if applicable).

NCT ID: NCT05824000 Completed - Dry Eye Clinical Trials

PMCF Study to Evaluate Performance and Safety of "Optrex Double Action Soothing and Lubricating Drops"

Start date: June 7, 2022
Phase: N/A
Study type: Interventional

Allergic conjunctivitis (or ocular allergy) and dry eye disease (DED) are two major ocular surface disorders affecting millions of people. A typical clinical symptom of allergic conjunctivitis is itching which is also observed in subjects suffering from DED. Common symptoms of DED also include a foreign body sensation, dryness, irritation, burning sensation and visual disturbance. Patients with allergic conjunctivitis or moderate-to-severe DED may experience a reduced quality of life due to ocular pain, difficulty in performing daily activities, and depression. Gel-based artificial tear supplements may offer longer retention times and act as a supplement to the mucin layer. Carbomer (also known as Carbopol polymers) is awater-soluble polymeric resin that exhibit excellent viscoelastic and mucoadhesive properties when compared with other polymers. Carbomer is used in liquid or semisolid pharmaceutical, cosmetics, and ophthalmic formulations as rheology modifiers. Aqueous carbomer gels have been used for the treatment of dry eye and allergic conjunctivitis as they provide prolonged ocular residence time of conventional ophthalmic solutions. Furthermore, carbomer has shown compatibility with many active ingredients, good thermal stability, excellent organoleptic characteristics, and good patient acceptance. 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 "Optrex Double Action soothing and lubricating drops" for itchy and watery eyes. 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 the use of "Optrex Double Action soothing and lubricating drops" 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, "Optrex Double Action soothing and lubricating drops" will be prescribed 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.

NCT ID: NCT05823961 Completed - Dry Eye Clinical Trials

PMCF Study to Evaluate Performance and Safety of "CLHA-based Eyedrops" Used to Improve Lacrimal Abnormalities

Start date: June 10, 2022
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT05807360 Completed - Dry Eye Clinical Trials

PMCF Study to Evaluate Performance and Safety of "Hyaluronic Acid (HA)-Based Eyedrops" Used to Relieve Dry Eye Symptoms

Start date: June 24, 2022
Phase: N/A
Study type: Interventional

Dry eye disease (DED), also called keratoconjunctivitis sicca, is a common ocular condition characterized by a loss of homeostasis of the tear film and inflammation of the ocular surface. The typical symptoms of DED include irritation, discomfort, blurred or fluctuating vision. Over the counter (OTC) artificial tears are typically the first line of dry eye treatment; they are meant to supplement the tears that cover the eye's surface. OTC products mimic the different layers of the tear film in order to maintain ocular hydration. HA is found in higher concentrations in the vitreous humor of the eye, cartilage, and the synovial fluid. As a component of the tear film, HA increases the viscosity of the tear film and hydrates and lubricates the ocular surface. HA possesses intrinsic water retention properties, viscoelasticity, and favors the healing of corneal and conjunctival epithelium. 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 "HA-based eyedrops" used as intended to relieve 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 "HA-based eyedrops" according to the IFU. "Hyaluronic Acid (HA)-based eyedrops" are medical devices used as intended to improve the discomfort due to dry eye (for intrinsic and/or extrinsic causes), contact lenses wearing and/or eye surgery. 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 (V0), one of the "Hyaluronic Acid (HA)-based eyedrops" products can be dispensed to the enrolled Subjects, depending on Investigator clinical evaluation, and severity of the disease. 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 (AEs) and concomitant medications intake.

NCT ID: NCT05775536 Completed - Dry Eye Clinical Trials

Detection of Acetylsalicylic Acid and Omega-3 Fatty Acids in Schirmers' Test Strips Using Mass Spectrometry

Start date: January 21, 2021
Phase: Phase 2
Study type: Interventional

Evaluation of tear fluid production using Schirmers' tests is a well-known and frequently used examination method in ophthalmology. Schirmers' test objectively indicates the tear fluid production over five minutes by insertion of a filter paper strip in the lower conjunctival fornix. Commonly, this method is used to quantify tear fluid production, but not tear fluid composition. The development of novel, very precise analytical methods opens up new possibilities in the use and application of Schirmers' test strips. A recently introduced analytical method is mass spectrometry. This method allows the detection and quantification of proteins, lipids, and metabolites in very low amounts of samples. Whether systemically ingested agents such as omega-3 fatty acids or acetylsalicylic acid can be detected in tear fluid using this method remains unclear. The aim of this study is to investigate the detectability of 2 different agents (acetylsalicylic acid and omega-3 fatty acids) in Schirmers' test strips from healthy subjects after intake for 1 week by use of untargeted mass spectrometry. Participating healthy subjects will receive either acetylsalicylic acid or omega-3 fatty acids.
