Active clinical trials for "Dry Eye Syndromes"

Background: Dry eye disease (DED) is a common condition causing burden on visual function and reducing quality of life. Corticosteroids and/or cyclosporine eye drops are able to improve DED symptoms, however, side effects of immune suppression and cost lead patients often to suspend treatment. Consequently, is important to identify therapies alleviating DED symptoms. A randomized, controlled, single masked study, was performed in 40 patients affected by mild to moderate DED, to evaluate efficacy and safety of a collyrium based on cross-linked hyaluronic acid (XLHA) added with Coenzyme Q10 (CoQ10) in comparison to an eye drop considered a gold standard for tear substitutes, based on hyaluronic acid (HA) 0.15%. Methods: eye drops were administered four times a day for 90 days to enrolled subjects divided in two groups: group A treated with XLHA+CoQ10, group B treated with HA. Ocular Surface Disease Index (OSDI) questionnaire, visual acuity, intraocular pressure (IOP), fundus exam, tear break-up time (TBUT), corneal and conjunctival fluorescein staining, corneal esthesiometry, corneal confocal microscopy, were performed at different visits until the 90th day.

The objective of this study is to assess safety and efficacy of DE-089 ophthalmic solution in patients with dry eye disease in Taiwan.

The primary objective of this study is to evaluate the efficacy of REMOGEN® OMEGA in reducing Dry Eye Syndrome (DES) symptoms.

The purpose of this study is to assess changes in meibomian gland function and evaporative dry eye symptoms after treatment with the iLux medical device.

Efficacy and Safety of the Ophthalmic Solution PRO-087 versus Systane ® Ultra and Systane ® Ultra Preservative Free on the Tear Film Dysfunction Syndrome from Mild to Moderate Clinical trial To evaluate the effectiveness of preservative-free ophthalmic formulation PRO-087 (by Laboratorios Sophia, S.A. de C.V.) to restore the anatomical and physiological characteristics of the ocular surface, as well as its distribution and the characteristics of the mild to moderate tear film dysfunction syndrome compared to Systane ® Ultra and Ultra Systane ® preservative free (by Laboratorios Alcon, S.A. de C.V.). Controlled, randomized, double-blind, masked clinical study, comparing the safety and efficacy of preservative-free PR0-087 vs Systane Ultra with preservative and Systane Ultra preservative free, in subjects with mild to moderate tear film dysfunction syndrome, for a period of 90 days plus 15 days of remote surveillance, in which one of the three agents will be administered (PR0-087, Systane® Ultra or Systane® Ultra preservative free) with a q.i.d. dosage. in both eyes, with regular follow-up visits (5 overall). Best-corrected visual acuity Intraocular pressure Ocular surface Anterior segment examination Posterior segment examination Tear film break-up time Schirmer test Corneal epithelization Goblet cells count Adverse events Subjects with a clinical diagnosis of mild to moderate tear film dysfunction syndrome between 18 and 90 years old, without concomitant eye diseases nor requiring different treatments of any of the three interventions in this study They will be randomized in 3 groups where PRO-087, Systane® Ultra o Systane® Ultra preservative free will be administered.

The purpose of this Phase 1/2 study is to compare the safety and tolerability of four times a day (QID) dosing of a non-preserved topical ocular drop formulation of 10 vol/vol % and 30 vol/vol % of FD hPL to vehicle control eye drops in patients with Dry Eye Disease (DED) secondary to Graft vs. Host Disease (GvHD).

A Multi-Center, Phase 2b, Randomized, Double Masked, Parallel-Group, Vehicle-Controlled, Clinical Study to Assess the Safety and Efficacy of Reproxalap Ophthalmic Solution (0.25% and 0.1%) Compared to Vehicle in Subjects with Dry Eye Disease

The objective of the Phase 2 study is to compare the safety and efficacy of cis-UCA Ophthalmic Solutions to placebo for the treatment of the signs and symptoms of dry eye.

BAK is one of the most frequent preservatives in eye drops. BAK is a quaternary ammonium salt with surfactant qualities. It can be bacteriostatic or bactericidal depending on the concentrations used. It has been shown to be effective against most bacteria with a few exceptions, such as Pseudomonas aeruginosa, or picornaviruses. It as been widely used in eyedrops, nose sprays, hand and face washes, mouthwashes, spermicidal creams, and in various other cleaners, sanitizers, and disinfectants. BAK gained popularity when it was first introduced because it also enhances corneal penetration of some drugs by causing epithelial separation. It is present in several ophthalmic formulations, including most of the antiglaucoma medications. If used chronically, BAK has been found to cause ocular surface changes, such as dry eye and punctuate keratitis. BAK has also been suggested to promote a break in the blood aqueous barrier, which may lead to undesirable consequences, such as uveitis and cystoid macular edema. However, this information is controversial. The purpose of this study is to evaluate the consequences of BAK on the blood-retinal and blood-aqueous barriers of pseudophakic patients receiving BAK-preserved lubricating drops.

Eyes with abnormal tear film function have been found to show larger optical aberrations than normal eyes which may be attributed to the unstable and irregular tear film, uneven ocular surface, and increased scatter due to the exposure of the rough surface of corneal epithelium after tear break-up. These hypotheses have been supported by the findings that instillation of artificial tears (sodium hyaluronate preparation) in dry eye patients reduces both corneal and ocular aberrations, improving the optical quality of the retinal image. However, the previous studies only evaluated the short-term effects of a single administration of an artificial tear but did not determine the duration of action or inflection point at which the ocular aberrations increase back to baseline. Also, there has clearly been no such clinical trial that has been a well randomized controlled study to date. This report is the first randomized controlled trial that investigated the long-term effects of a single dose of sodium hyaluronate-based artificial tears on wavefront aberrations in patients with dry eye.
