Filter by:Glaucoma is the most frequent cause of irreversible & preventable blindness worldwide, affecting about 2% of the world's population in people over 40. The major risk factor, and only treatable factor in glaucoma, is increased intraocular pressure (IOP). IOP reduction can slow or arrest the progression of vision loss. Current treatment consists of drops administered on a daily basis with unfortunately low patient compliance, increasing the chance of blindness. Eximore's product aims to eliminate the need to apply eye drops on a daily basis and thus solves the significant problem of patient compliance.
To test the safety and effectiveness of AR-13324 0.02% and 0.04% ophthalmic solution relative to placebo in Japanese/Japanese-American subjects with open-angle glaucoma or ocular hypertension in US.
This is a Phase I, multi-center, randomized, adaptive, investigator/patient-masked, placebo-controlled, parallel multiple-ascending dose study (Part A) with an extension including up to two selected doses from Part A and latanoprost 0.005% as active comparator (Part B).
The study is intended to test the effectiveness and safety of Netarsudil / Latanoprost 0.02% / 0.005% Ophthalmic Solution, relative to GANFORT® for lowering of intraocular pressure (IOP) in patients with elevated intraocular pressure
Aim: To demonstrate the non-inferiority of the PRO-122 ophthalmic solution manufactured by Laboratorios Sophia S.A. de C.V. versus Krytantek Ofteno® ophthalmic solution like hypotensive therapy in subjects with primary open angle glaucoma or ocular hypertension. Study design: a multicentric, prospective, crossover (2x2), double blind clinical study. Sample size: one hundred patients with primary open angle glaucoma or ocular hypertension. Patients in the period 1: In the first sequence 30 patients will be assigned to receive the ophthalmic solution: Krytantek Ofteno ® (timolol 0.5%%/brimonidine 0.2%/dorzolamide 2%) 1 drop B.I.D. during 30 days and the second sequence 30 patients will be assigned to receive the ophthalmic solution: PRO-122 1 drop B.I.D. during 30 days in the same period. Washout period: 20 hours. Patients in the period 2: the pharmacological intervention change to the opposite therapy for 30 days
Glaucoma is one of the most prevalent eye diseases and the second most common cause of blindness worldwide. The most common form is primary open angle glaucoma (POAG). Glaucoma is a slowly progressing neuropathy of the optic nerve that causes loss of visual field and eventually blindness. Elevated intra-ocular pressure (IOP) is the most important risk factor. Corticosteroids, which are often used for the treatment of many diseases in ophthalmology and other specialities, may cause an elevation of the IOP. It is estimated that corticosteroids induce ocular hypertension in approximately 18%-36% of the general population and in patients with POAG this percentage can be as high as 92%. When the treatment is sustained, this can cause a glaucomatous neuropathy of the optic nerve (corticosteroid-induced glaucoma). The precise pathogenic mechanism isn't clear yet. Genetic factors are likely to affect the susceptibility to corticosteroid response. Therefore, an overview of the genetic mechanisms of corticosteroid-induced glaucoma can give more insight in the pathogenesis. In this study the researchers investigate the occurrence of SNPs (single nucleotide polymorphisms) in 150 cases with a steroid-response in comparison with 300 controls exposed to corticosteroids without a steroid-response. Up to now, one small GWAS has been conducted comparing 32 patients with and without corticosteroid-induced ocular hypertension after treatment with intravitreal triamcinolone. In this study, two SNPs proximal of the transcriptional start site (near the 5') of HCG22 on chromosome 6 were identified. However, this is a rather small sample population and the investigators didn't match for the underlying disease. Further, in another small study, Hogewind et al. performed SNP analysis in multiple genes (SFRS3, FKBP4, FKBP5, and NR3C1) in corticosteroid-induced ocular hypertension. This study enables the investigators to identify patients at risk for developing corticosteroid-induced glaucoma and to gain a better insight in the pathogenesis. This may also lead to the discovery of biomarkers that indicate an increased risk of developing a steroid-induced glaucoma and new prevention and treatment strategies, which are necessary as the treatment of corticosteroid induced-glaucoma now only focuses at lowering the IOP and can still be challenging.
The purpose of this study is to evaluate the clinical efficacy of the BREMEN eye drops in the treatment of primary open-angle glaucoma or intraocular hypertension.

Treatment of elevated pressure in the eye (Intraocular pressure, or 'IOP') with eye drop medications has been shown to be effective in delaying or preventing the progression of glaucoma, and it is the only proven method for reducing the risk of glaucomatous visual field loss. This study is being conducted to determine how well DE-126 ophthalmic solution works (efficacy) in safely lowering IOP when dosed as topical eyedrops. This study will evaluate the safety and efficacy of four (4) concentrations of DE-126, when compared with latanoprost (0.005%) eye drops in patients with primary open-angle glaucoma or ocular hypertension. The IOP will be measured at 3 different times throughout the day, over 6 total visits during a 3-month treatment period (with up to 4 extra weeks observation if the patient must stop taking current eye drops to lower IOP). Safety assessments will be done throughout the study, including ocular signs and symptoms, vital signs, and clinical laboratory tests. While the most important time-point to measure IOP in this study and evaluate efficacy will be at the final study visit (month 3), IOP values will also be evaluated at other visits throughout the 3-month treatment period.
Studies have shown that ocular surface disease (OSD) is common among patients with glaucoma with a prevalence of 50% or more. The percentage of affected patients appears to increase with increasing number of topical anti-glaucoma products instilled. Both pre-clinical and clinical work has indicated that the preservatives used in anti-glaucoma drops, particularly benzalkonium chloride, are mainly responsible for this detrimental effect. As such more and more anti-glaucoma drugs without preservatives entered the market. To prove that switching from preserved to unpreserved antiglaucoma medication improves the signs and symptom of OSD is, however, not easy. This is on the one hand related to the physiological variability of these parameters over time and on the other hand to the poor association between signs and symptoms. Recently, a new method for measuring tear film thickness (TFT) using ultra-high resolution optical coherence tomography (OCT) has been introduced. Using this method, it has been shown that there is a correlation between reduced TFT and OSD symptoms. In the present study, it is hypothesized that changing patients who are on preserved prostaglandin formulations to preservative free tafluprost may be associated with an increase in TFT.
