Abstract
Glaucoma is a chronic neurodegenerative disease that poses a significant threat of irreversible blindness worldwide. Current treatments for glaucoma focus on reducing intraocular pressure (IOP), which is the only modifiable risk factor. Traditional anti-glaucomatous agents, including carbonic anhydrase inhibitors, beta-blockers, alpha-2 agonists, and prostaglandin analogs, work by either improving uveoscleral outflow or reducing aqueous humor production. Rho kinase (ROCK) inhibitors represent a novel class of anti-glaucomatous drugs that have emerged from bench to bedside in the past decade, offering multifunctional characteristics. Unlike conventional medications, ROCK inhibitors directly target the trabecular meshwork outflow pathway. This review aims to discuss the mechanism of ROCK inhibitors in reducing IOP, providing neuroprotection, and preventing fibrosis. We also highlight recent studies and clinical trials evaluating the efficacy and safety of ROCK inhibitors, compare them with other clinical anti-glaucomatous medications, and outline future prospects for ROCK inhibitors in glaucoma treatment.

Abstract
Glaucoma is a leading cause of irreversible blindness which preferentially affects older individuals. No medications or therapies which are currently in our arsenal actually treat glaucoma itself. We know that intraocular pressure (IOP) is currently the only modifiable risk factor for glaucoma. The primary treatments for glaucoma include medications, laser therapies, and surgical therapies. The Rho kinase inhibitors are the newest class of medications currently on the market and in development for topical IOP-lowering therapy. Studies have shown their ability to lower eye pressure individually and in combination with other medications. Their ability to potentially provide neuroprotective effects for disease modification also gives this class exciting potential for glaucoma treatment.

BIOLOGY 2024; 13:115. [PMID: 38392332 PMCID: PMC10886476 DOI: 10.3390/biology13020115] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/20/2023] [Revised: 02/05/2024] [Accepted: 02/09/2024] [Indexed: 02/24/2024]
Abstract
Rho-kinase inhibitors have been identified as a class of potential drugs for treating asthma because of their ability to reduce airway inflammation and active force in airway smooth muscle (ASM). Past research has revealed that, besides the effect on the ASM's force generation, rho-kinase (ROCK) also regulates actin filament formation and filament network architecture and integrity, thus affecting ASM's cytoskeletal stiffness. The present review is not a comprehensive examination of the roles played by ROCK in regulating ASM function but is specifically focused on passive tension, which is partially determined by the cytoskeletal stiffness of ASM. Understanding the molecular basis for maintaining active force and passive tension in ASM by ROCK will allow us to determine the suitability of ROCK inhibitors and its downstream enzymes as a class of drugs in treating airway hyperresponsiveness seen in asthma. Because clinical trials using ROCK inhibitors in the treatment of asthma have yet to be conducted, the present review focuses on the in vitro effects of ROCK inhibitors on ASM's mechanical properties which include active force generation, relaxation, and passive stiffness. The review provides justification for future clinical trials in the treatment of asthma using ROCK inhibitors alone and in combination with other pharmacological and mechanical interventions.

Abstract
Recent advancements in prostaglandin analogs (PGAs) have reinforced their role in managing intraocular pressure (IOP). Latanoprost excels in 24-h IOP control, while various PGAs offer similar effectiveness and side effects, generic PGAs perform as well as branded ones, and a notable IOP rise observed upon PGA discontinuation. Formulations with or without preservatives show comparable IOP reduction and adherence, often surpassing benzalkonium chloride (BAK)-preserved options. Emergent PGAs, such as latanoprostene bunod, fixed-dose netarsudil combined with latanoprost, and omidenepag Isopropyl, offer enhanced or non-inferior IOP reduction. The bimatoprost implant introduces a novel administration method with effective IOP reduction. These developments underscore ongoing progress in PGA-focused ophthalmological research. This article offers a comprehensive review of available prostanoid analogs and explores new developments.

MERCURY-3: a randomized comparison of netarsudil/latanoprost and bimatoprost/timolol in open-angle glaucoma and ocular hypertension. Graefes Arch Clin Exp Ophthalmol 2024; 262:179-190. [PMID: 37615697 PMCID: PMC10806046 DOI: 10.1007/s00417-023-06192-0] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2023] [Revised: 06/22/2023] [Accepted: 07/23/2023] [Indexed: 08/25/2023] Open
Abstract
PURPOSE : To compare the efficacy and safety of the fixed-dose combination (FDC) of netarsudil 0.02%/latanoprost 0.005% ophthalmic solution (NET/LAT; Roclanda®) with bimatoprost 0.03%/timolol maleate 0.5% (BIM/TIM; Ganfort®) ophthalmic solution in the treatment of open-angle glaucoma (OAG) and ocular hypertension (OHT). METHODS MERCURY-3 was a 6-month prospective, double-masked, randomized, multicenter, active-controlled, parallel-group, non-inferiority study. Patients (≥ 18 years) with a diagnosis of OAG or OHT in both eyes that was insufficiently controlled with topical medication (IOP ≥ 17 mmHg in ≥ 1 eye and < 28 mmHg in both eyes) were included. Following washout, patients were randomized to once-daily NET/LAT or BIM/TIM for up to 6 months; efficacy was assessed at Week 2, Week 4, and Month 3; safety was evaluated for 6 months. Comparison of NET/LAT relative to BIM/TIM for mean IOP at 08:00, 10:00, and 16:00 h was assessed at Week 2, Week 6, and Month 3. Non-inferiority of NET/LAT to BIM/TIM was defined as a difference of ≤ 1.5 mmHg at all nine time points through Month 3 and ≤ 1.0 mmHg at five or more of nine time points through Month 3. RESULTS Overall, 430 patients were randomized (NET/LAT, n = 218; BIM/TIM, n = 212), and all received at least one dose of study medication. Efficacy analyses were performed at Month 3 on 388 patients (NET/LAT, n = 184; BIM/TIM, n = 204). NET/LAT demonstrated non-inferiority to BIM/TIM, with a between-treatment difference in IOP of ≤ 1.5 mmHg achieved at all time points and ≤ 1.0 mmHg at the majority of time points (six of nine) through Month 3. Mean diurnal IOP during the study ranged from 15.4 to 15.6 mmHg and 15.2 to 15.6 mmHg in the NET/LAT and BIM/TIM groups respectively, with no between-group statistically significant difference. No significant differences were observed in key secondary endpoints. No serious, treatment-related adverse events (AEs) were observed, and AEs were typically mild/moderate in severity. The most common treatment-related AEs were conjunctival hyperemia (NET/LAT, 30.7%; BIM/TIM, 9.0%) and cornea verticillata (NET/LAT, 11.0%; BIM/TIM, 0%). CONCLUSIONS Once-daily NET/LAT was non-inferior to BIM/TIM in IOP reduction in OAG and OHT, with AEs consistent with previous findings. NET/LAT offers a compelling alternative FDC treatment option for OAG and OHT.

Abstract
Rho kinase (ROCK) inhibitors have gained significant attention as emerging novel treatment options in the field of ophthalmology in recent years. The evidence supporting their efficacy in glaucoma and corneal pathology includes both in vitro and clinical studies. Among the available options, ripasudil and netarsudil have emerged as the leading ROCK inhibitors, and some countries have approved these therapeutic options as treatments for glaucoma. Various dosing regimens have been studied, including monotherapy and combination therapy, especially for patients with secondary glaucoma who are already on multiple medications. Another rising application of ROCK inhibitors includes their use as an adjunct in surgical procedures such as Descemetorhexis Without Endothelial Keratoplasty (DWEK), Descemet Stripping Only (DSO) to accelerate visual recovery, glaucoma surgeries to reduce scarring process and allow better intraocular pressure (IOP) control, or after complicated anterior segment surgery to treat corneal oedema. This article provides a comprehensive overview of the existing literature in the field, offering recommendations for prescribing ROCK inhibitors and also discussing patient selection, drug efficacy, and possible adverse effects.

Abstract
Serious vision loss occurs in patients affected by chronically raised intraocular pressure (IOP), a characteristic of many forms of glaucoma where damage to the optic nerve components causes progressive degeneration of retinal and brain neurons involved in visual perception. While many risk factors abound and have been validated for this glaucomatous optic neuropathy (GON), the major one is ocular hypertension (OHT), which results from the accumulation of excess aqueous humor (AQH) fluid in the anterior chamber of the eye. Millions around the world suffer from this asymptomatic and progressive degenerative eye disease. Since clinical evidence has revealed a strong correlation between the reduction in elevated IOP/OHT and GON progression, many drugs, devices, and surgical techniques have been developed to lower and control IOP. The constant quest for new pharmaceuticals and other modalities with superior therapeutic indices has recently yielded health authority-approved novel drugs with unique pharmacological signatures and mechanism(s) of action and AQH drainage microdevices for effectively and durably treating OHT. A unique nitric oxide-donating conjugate of latanoprost, an FP-receptor prostaglandin (PG; latanoprostene bunod), new rho kinase inhibitors (ripasudil; netarsudil), a novel non-PG EP2-receptor-selective agonist (omidenepag isopropyl), and a form of FP-receptor PG in a slow-release intracameral implant (Durysta) represent the additions to the pharmaceutical toolchest to mitigate the ravages of OHT. Despite these advances, early diagnosis of OHT and glaucoma still lags behind and would benefit from further concerted effort and attention.

Abstract
Rho kinase (ROCK) inhibitors have emerged as a key therapeutic class of interest in ophthalmology over the last decade. Promising in vitro studies laid the foundations for the development of novel therapeutic agents that target the ROCK signalling pathway in ocular disease, with subsequent clinical trials supporting their use. Corneal endothelial disease, glaucoma, and vitreoretinal disease are the major pathologies in which ROCK inhibitors have been investigated to date. Ripasudil and netarsudil represent the current leaders in this pharmaceutical group, having been extensively validated and approved for use in glaucoma in some countries. Less substantial evidence exists for fasudil in ophthalmic use. ROCK inhibitors are also increasingly used in cultured endothelial cell grafting and as an adjunct to aid in endothelial cell migration and replication in Descemet's stripping procedures or Descemet's membrane injuries. This review has synthesised both established and emerging research to provide a practical guide to prescribing in this drug class. Drug efficacies, side effect profiles, and the demographic and clinical characteristics of appropriate drug candidates are discussed.

Abstract
INTRODUCTION Fixed-combination bimatoprost 0.03%/timolol 0.5% ophthalmic solution (FCBT; Ganfort®, Allergan, an AbbVie company) effectively reduces intraocular pressure (IOP) via complementary mechanisms of action of the agents, but long-term (> 12 weeks) safety evaluations of FCBT remain limited. FCBT safety is evaluated herein, with particular focus on hyperemia and eyelash growth, at 24 weeks in Chinese patients with open-angle glaucoma (OAG) or ocular hypertension (OHT). METHODS In this multicenter, open-label, noncomparative, phase 4 study conducted in China, patients diagnosed with OAG or OHT having insufficient response to β-blocker- or prostaglandin analogue/prostamide (PGA)-based IOP-lowering monotherapy in one or both eyes were switched from their current IOP-lowering treatment to FCBT (one drop per eye every evening) without prior washout. Assessment visits were scheduled at baseline and weeks 4, 12, and 24 (or study exit). The primary outcome measure was adverse event (AE) incidence through 24 weeks. RESULTS Of 725 patients enrolled, 632 (87.2%) completed the study; 93 (12.8%) patients discontinued, including 29 (4.0%) due to AEs. Of 1326 FCBT-treated eyes (total), 594 (44.8%) experienced ≥ 1 ocular treatment-related AE during the study. Conjunctival hyperemia (the most common AE overall) and eyelash growth were reported in 269 (20.3%) and 54 (4.1%) FCBT-treated eyes, respectively. The incidence of other known PGA-related AEs (including blepharal pigmentation and erythema of eyelid) was < 10% each. Most conjunctival hyperemia reports were mild in severity (214/259; 82.6%) and only 1/259 (0.4%) was severe. Similarly, most cases of eyelash growth were mild (46/52; 88.5%); none were severe. One (< 0.1%) FCBT-treated eye had a serious ocular AE (OAG) considered FCBT-related. CONCLUSIONS The frequency and severity of FCBT-related AEs, including conjunctival hyperemia and eyelash growth, are consistent with previously published findings. No new safety concerns were raised. This prospective study reaffirms that once-daily FCBT is a safe and well-tolerated therapy for OAG and OHT. CLINICALTRIALS GOV IDENTIFIER NCT02571712.

Abstract
Aim This review summarizes current data on Rho-kinase (ROCK) inhibitors use in ocular diseases, primarily glaucoma. Background Translational research over the last decade culminating in the development of ROCK inhibitors has provided a much-needed shot in the arm to glaucoma pharmacopeia. ROCK pathway is intricately involved in cytoskeletal modulation with action on cell morphology, cell motility, cell adhesion, cell apoptosis, and smooth muscle contraction. This cytoskeletal modulation property has been utilized to modify trabecular meshwork (TM) resistance, resulting in the discovery of ROCK inhibitors to increase trabecular outflow. Review results Multicentric trials on ROCK inhibitors for antiglaucoma medications are summarized. The focus is on linking pharmacological action to the clinical utility of these drugs. While the Rho Kinase Elevated intraocular Pressure (IOP) Treatment (ROCKET) trials compared monotherapy with ROCK inhibitor netarsudil vs timolol, MERCURY trials compared a fixed dose combination of latanoprost and ROCK inhibitor netarsudil [fixed combination netarsudil-latanoprost (FCNL)] vs monotherapy with either and bimatoprost-timolol combination. While ROCKET trials showed ROCK inhibitors to be non-inferior to timolol, MERCURY trials showed FCNL achieving a much greater IOP reduction than monotherapy with either. Conjunctival hyperemia was the most common side effect reported with ROCK inhibitor use. Conclusion Moderate efficacy of ROCK inhibitors with a common side effect of conjunctival hyperemia, makes it an adjunctive antiglaucoma drug of choice and not a first-line therapy. Clinical significance ROCK inhibitors' action on diseased TM is more physiological compared to available antiglaucoma medications that either reduce aqueous secretion or enhance uveoscleral outflow. The property of ROCK inhibition to stabilize the endothelium of both retinal vasculature and cornea has opened a new chapter in the treatment of diabetic retinopathy and corneal decompensation.

Abstract
PURPOSE To evaluate the efficacy of topical netarsudil 0.02% as adjunctive therapy in children with refractory pediatric glaucoma. METHODS The medical records of patients ≤18 years diagnosed with pediatric glaucoma treated with topical netarsudil 0.02% from June 2019 to March 2022 were reviewed retrospectively. Data collected included age, sex, ethnicity, etiology of glaucoma, history of previous or subsequent glaucoma surgery, and intraocular pressure (IOP) before and after the addition of topical netarsudil. RESULTS A total of 21 eyes of 16 patients (11 males) were included. Five patients used topical netarsudil in both eyes. Eight patients were Hispanic. The mean number of glaucoma surgeries and medications before initiating topical netarsudil was 1.8 ± 1.2 and 3.7 ± 0.5, respectively. The mean age prior to starting topical netarsudil was 8.9 ± 4.1 years. The mean follow-up after initiating topical netarsudil was 11.3 ± 8.2 months. The IOP was significantly reduced from 26.3 ± 6.2 mm Hg before topical netarsudil to 19.6 ± 6.02 mm Hg at 1 month in 15 eyes (P < 0.01), 18.2 ± 6.9 mm Hg at 3-months in 18 eyes (P < 0.01), 18.3 ± 7.3 mm Hg at 6 months in 13 eyes (P = 0.01), 17.6 ± 5.07 mm Hg at 9 months in 14 eyes (P = 0.002), and 17.4 ± 3.1 mm Hg at 12 months in 13 eyes (P = 0.002). Nine eyes (43%) underwent additional glaucoma surgery due to long-term failure of topical netarsudil to reduce IOP despite an initial reduction, and one eye had persistent IOP elevation ≥21 mm Hg despite the addition of topical netarsudil. CONCLUSIONS In our small cohort of patients with refractory pediatric glaucoma, the addition of topical netarsudil reduced IOP, potentially delaying the need for surgery.

[PMID: 36274674 PMCID: PMC9582300 DOI: 10.2147/opth.s369626] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2022] [Accepted: 08/22/2022] [Indexed: 11/16/2022] Open
Abstract
Introduction To evaluate the intraocular pressure (IOP)-lowering efficacy and safety of a triple fixed-combination of bimatoprost, brimonidine, and timolol (TFC) in patients with glaucoma or ocular hypertension (OHT) treated with fixed-combination or unfixed brimonidine and timolol therapy (dual-combination therapy). Methods In this multicenter, open-label, phase 3 study, patients who received 4-8 weeks of dual-combination therapy twice daily and had an IOP >18 and <34 mmHg in at least one eye were switched (at baseline) to treatment with TFC twice daily for 12 weeks. At Weeks 4, 8, and 12 on TFC, IOP was assessed at Hours 0, 2, and 8. Primary efficacy variable: mean diurnal IOP change from baseline in the study eye at Week 12 (modified intent-to-treat [mITT] population). Sensitivity (per-protocol [PP] population) and subgroup (≤65 vs >65 years) analyses were performed. Safety, including adverse events (AEs), was assessed at each visit. Results Of 126 patients enrolled, 121 and 103 formed the mITT/safety and PP populations, including 109 (90.1%) and 94 (91.3%) who completed the study, respectively. In the mITT/safety population, mean age was 58.6 years. Patients had open-angle glaucoma (51.2%), angle-closure glaucoma with patent iridotomy (36.4%), and/or OHT (13.2%). At Week 12, the mean diurnal change in IOP from dual combination-treated baseline was statistically significant (P<0.001) with TFC in the mITT (-3.98 mmHg) and PP (-4.22 mmHg) populations. Results were similar at all visits, regardless of the age subgroup. The most frequent treatment-related AEs were conjunctival hyperemia (14.0%) and dry eye (4.1%); 5.8% of the patients discontinued treatment due to ocular AEs. Conclusion TFC offers a beneficial therapeutic alternative for patients with glaucoma or OHT whose IOP is not sufficiently controlled with dual-combination therapy. Safety and efficacy findings support those of published studies of TFC in primary open-angle glaucoma and OHT, despite differences in study designs.

Abstract
ObjectiveAs monotherapy is insufficient for some patients, the existing fixed-dose combination (FDC) requires two or more daily administrations with declining adherence. The present study compared the efficacy and safety of netarsudil/latanoprost FDC with monotherapy of its individual components in patients with glaucoma.MethodsA systematic literature search was performed for studies comparing netarsudil/latanoprost fixed-dose combination (FDC) vs. monotherapy in patients with glaucoma. The primary endpoints included intraocular pressure (IOP), intraocular pressure reduction percentage (IOPR%) and adverse events (AEs).ResultsThree randomized controlled trial studies (RCTs) involving 1,692 patients (FDC: 556, netarsudil: 577, latanoprost: 559) were included in this meta-analysis. FDC was more effective than netarsudil, with significantly lower diurnal IOP over three time points (8:00 a.m., 10:00 a.m., 4:00 p.m.), mean diurnal IOP (MD = −2.36 [−3.08, −1.63], P < 0.00001) and higher IOPR% (MD = 9.60 [7.86, 11.33], P < 0.00001). When comparing FDC with latanoprost, both mean diurnal IOP (MD = −1.64 [−2.05, −1.23], P < 0.00001) and diurnal IOP across 3 time points were significantly lower with FDC than with latanoprost, while FDC induced significantly higher IOPR% (MD = 6.09 [4.40, 7.77], P < 0.00001). Incidence of total AEs was similar between netarsudil and FDC, but higher with FDC than with latanoprost.ConclusionNetarsudil/latanoprost FDC appears to be superior to netarsudil or latanoprost alone, with better ocular hypotensive effects. However, there are concerns that netarsudil/latanoprost FDC was associated with a significantly higher incidence of AEs specifically compared with latanoprost.Systematic review registrationhttps://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=311956.

Abstract
BACKGROUND Glaucoma is a group of optic neuropathies characterized by progressive degeneration of the retinal ganglion cells, axonal loss and irreversible visual field defects. Glaucoma is classified as primary or secondary, and worldwide, primary glaucoma is a leading cause of irreversible blindness. Several subtypes of glaucoma exist, and primary open-angle glaucoma (POAG) is the most common. The etiology of POAG is unknown, but current treatments aim to reduce intraocular pressure (IOP), thus preventing the onset and progression of the disease. Compared with traditional antiglaucomatous treatments, rho kinase inhibitors (ROKi) have a different pharmacodynamic. ROKi is the only current treatment that effectively lowers IOP by modulating the drainage of aqueous humor through the trabecular meshwork and Schlemm's canal. As ROKi are introduced into the market more widely, it is important to assess the efficacy and potential AEs of the treatment. OBJECTIVES To compare the efficacy and safety of ROKi with placebo or other glaucoma medication in people diagnosed with open-angle glaucoma (OAG), primary open-angle glaucoma (POAG) or ocular hypertension (OHT). SEARCH METHODS We used standard Cochrane methods and searched databases on 11 December 2020. SELECTION CRITERIA We included randomized clinical trials examining commercially available ROKi-based monotherapy or combination therapy compared with placebo or other IOP-lowering medical treatments in people diagnosed with (P)OAG or OHT. We included trials where ROKi were administered according to official glaucoma guidelines. There were no restrictions regarding type, year or status of the publication. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. Two review authors independently screened studies, extracted data, and evaluated risk of bias by using Cochrane's RoB 2 tool. MAIN RESULTS: We included 17 trials with 4953 participants diagnosed with (P)OAG or OHT. Fifteen were multicenter trials and 15 were masked trials. All participants were aged above 18 years. Trial duration varied from 24 hours to 12 months. Trials were conducted in the USA, Canada and Japan. Sixteen trials were funded by pharmaceutical companies, and one trial provided no information about funding sources. The trials compared ROKi monotherapy (netarsudil or ripasudil) or combination therapy with latanoprost (prostaglandin analog) or timolol (beta-blocker) with placebo, timolol, latanoprost or netarsudil. Reported outcomes were IOP and safety. Meta-analyses were applied to 13 trials (IOP reduction from baseline) and 15 trials (ocular AEs). Of the trials evaluating IOP, seven were at low risk, three had some concerns, and three were at high risk of bias. Three trials found that netarsudil monotherapy may be superior to placebo (mean difference [MD] 3.11 mmHg, 95% confidence interval [CI] 2.59 to 3.62; I2 = 0%; 155 participants; low-certainty evidence). Evidence from three trials found that timolol may be superior to netarsudil with an MD of 0.66 mmHg (95% CI 0.41 to 0.91; I2 = 0%; 1415 participants; low-certainty evidence). Evidence from four trials found that latanoprost may be superior to netarsudil with an MD of 0.97 mmHg (95% CI 0.67 to 1.27; I2 = 4%; 1283 participants; moderate-certainty evidence). Evidence from three trials showed that, compared with monotherapy with latanoprost, combination therapy with netarsudil and latanoprost probably led to an additional pooled mean IOP reduction from baseline of 1.64 mmHg (95% CI -2.16 to -1.11; 1114 participants). Evidence from three trials showed that, compared with monotherapy with netarsudil, combination therapy with netarsudil and latanoprost probably led to an additional pooled mean IOP reduction from baseline of 2.66 mmHg (95% CI -2.98 to -2.35; 1132 participants). The certainty of evidence was moderate. One trial showed that, compared with timolol monotherapy, combination therapy with ripasudil and timolol may lead to an IOP reduction from baseline of 0.75 mmHg (95% -1.29 to -CI 0.21; 208 participants). The certainty of evidence was moderate. Of the trials assessing total ocular AEs, three were at low risk, four had some concerns, and eight were at high risk of bias. We found very low-certainty evidence that netarsudil may lead to more ocular AEs compared with placebo, with 66 more ocular AEs per 100 person-months (95% CI 28 to 103; I2 = 86%; 4 trials, 188 participants). We found low-certainty evidence that netarsudil may lead to more ocular AEs compared with latanoprost, with 29 more ocular AEs per 100 person-months (95% CI 17 to 42; I2 = 95%; 4 trials, 1286 participants). We found moderate-certainty evidence that, compared with timolol, netarsudil probably led to 21 additional ocular AEs (95% CI 14 to 27; I2 = 93%; 4 trials, 1678 participants). Data from three trials (1132 participants) showed no evidence of differences in the incidence rate of AEs between combination therapy with netarsudil and latanoprost and netarsudil monotherapy (1 more event per 100 person-months, 95% CI 0 to 3); however, the certainty of evidence was low. Similarly, we found low-certainty evidence that, compared with latanoprost, combination therapy with netarsudil and latanoprost may cause 29 more ocular events per 100 person-months (95% CI 11 to 47; 3 trials, 1116 participants). We found moderate-certainty evidence that, compared with timolol monotherapy, combination therapy with ripasudil and timolol probably causes 35 more ocular events per 100 person-months (95% CI 25 to 45; 1 trial, 208 participants). In all included trials, ROKi was reportedly not associated with any particular serious AEs. AUTHORS' CONCLUSIONS The current evidence suggests that in people diagnosed with OHT or (P)OAG, the hypotensive effect of netarsudil may be inferior to latanoprost and slightly inferior to timolol. Combining netarsudil and latanoprost probably further reduces IOP compared with monotherapy. Netarsudil as mono- or combination therapy may result in more ocular AEs. However, the certainty of evidence was very low or low for all comparisons except timolol. In general, AEs were described as mild, transient, and reversible upon treatment discontinuation. ROKi was not associated with any particular serious AEs. Future trials of sufficient size and follow-up should be conducted to provide reliable information about glaucoma progression, relevant IOP measurements and a detailed description of AEs using similar terminology. This would ensure the robustness and confidence of the results and assess the intermediate- and long-term efficacy and safety of ROKi.

Abstract
Purpose To describe a previously unreported case of reversible myopic shift with corresponding changes in corneal contour in a patient treated with netarsudil/latanoprost. Observations A 72-year-old male with history of primary open angle glaucoma, prior cataract surgery, and remote radial keratotomy surgery was treated with fixed-dose combination of netarsudil/latanoprost. Despite no prior history of refractive shift in the twenty years since radial keratotomy surgery, on one month follow-up, he reported reduced visual acuity and presented with approximately 1.50 D shift in both eyes. There were associated corneal contour changes. No corneal epithelial bullae or edema were appreciated. Netarsudil/latanoprost was discontinued and timolol was initiated. One month later, both refractive error and corneal contour returned to prior levels. Conclusions Netarsudil is a rho-kinase and norepinephrine transporter inhibitor that may be effective in the treatment of primary open angle glaucoma resistant to other topical treatments. In addition to corneal epithelial bullous edema previously reported, this drug may induce reversible changes in corneal contour in patients with prior corneal or refractive surgery.

Abstract
PURPOSE To compare the intraocular pressure (IOP)-lowering effects of netarsudil on goniotomy-treated eyes versus goniotomy-naïve control eyes. METHODS Retrospective cohort study of 70 eyes from 49 adult glaucoma patients treated with netarsudil. Thirty-five eyes received sectoral goniotomy using Kahook Dual Blade (KDB) combined with cataract surgery with minimum of 3 months prior to netarsudil treatment. Thirty-five eyes in the control cohort received only cataract surgery prior to netarsudil. Primary outcome was treatment success, defined as ≥ 20% decrease in IOP at minimum 1 month follow-up. Secondary outcome measures included percent of IOP reduction, adverse effects of medication, medication discontinuation rate, and relationship between KDB goniotomy response and netarsudil response. RESULTS Eighty-three percent of KDB-treated eyes achieved netarsudil treatment success compared to 54% of control eyes (P = .012). IOP reduction was 30.3 ± 16.2% (IQR 21-38%) in KDB-treated eyes and 19.4 ± 12.4% (IQR 9.2-30.8) in control eyes (P = .007). History of prior KDB increased the likelihood of success to netarsudil treatment compared to eyes without prior KDB, regardless of surgical response to KDB (odds ratio 4.51, 95% CI 1.34-15.14, P = .015). The overall rate of adverse effects of netarsudil was 42%, most commonly reported as conjunctival hyperemia, allergy, and blurred vision. CONCLUSIONS Netarsudil had a greater IOP-lowering effect in eyes treated with prior goniotomy and may serve as a promising adjunctive ocular hypotensive agent to further reduce IOP in eyes with prior goniotomy.

Abstract
PURPOSE To evaluate the intraocular pressure (IOP)-reducing efficacy and safety of Rho-kinase inhibitor (RKI). METHODS Published studies in PubMed and EMBASE were searched on March 20, 2021. Study selection and data extraction were performed according to PRISMA. Meta-analysis of the IOP-lowering effect was performed with the bivariate random-effects model, with studies categorized into 2 classes: RKI versus placebo and RKI versus another medication. The main outcome was the difference in IOP reduction between RKI and non-RKI groups. Subgroup analysis of adjunctive RKI efficacy and additional review of its major ocular adverse events (AE) were also performed. RESULTS Ten (2.6%) out of 391 studies were retrieved. In the RKI versus placebo class, RKI showed greater IOP reduction after 4-8 weeks (mean difference = - 1.69 mmHg [- 2.22, - 1.16], P < 0.001). In the RKI versus another medication class, IOP reduction by RKI was noninferior to timolol 0.5% twice-daily after 4-8 weeks (mean difference = 0.39 mmHg [0.01, 0.76], P = 0.043) and 12 weeks (mean difference = 0.48 mmHg [0.11, 0.85]; P = 0.011). In the subgroup analysis, the mean difference in IOP reduction by adjunctive RKI and placebo was - 1.42 mmHg (P < 0.001). The most common ocular AE of RKI was conjunctival hyperemia (19-65%), followed by conjunctival hemorrhage (6-20%) and cornea verticillata (13-26%). CONCLUSIONS With a treatment duration of 1-3 months, RKI showed effective IOP reduction noninferior to timolol as monotherapy and as adjunctive therapy. Our results suggested RKI be a reliable IOP control medication; however, its higher incidence of some ocular complications should be attended to.

Abstract
BACKGROUND A variety of shared care models have been developed, which aim to stratify glaucoma patients according to risk of disease progression. However, there is limited published data on the rate of glaucoma progression in the hospital vs community setting. Here we aimed to compare rates of glaucomatous visual field progression in the Cambridge Community Optometrist Glaucoma Scheme (COGS) and Addenbrooke's Hospital Glaucoma Clinic (AGC). METHODS A retrospective comparative cohort review was performed. Patients with five or more visual field tests were included. Zeiss Forum software was used to calculate the MD progression rate (dB/year). Loss of sight years (LSY) were also calculated for both COGS and AGC. RESULTS Overall, 8465 visual field tests from 854 patients were reviewed. In all, 362 eyes from the AGC group and 210 eyes from COGS were included. The MD deterioration rate was significantly lower in the COGS patients compared with the AGC group (-0.1 vs -0.3 dB/year; p < 0.0001). No patients in the COGS group were predicted to become blind within their lifetime by LSY analysis. Fifteen patients were at risk in the AGC group. CONCLUSION This service evaluation shows that COGS is an effective scheme to stratify lower risk glaucoma patients, increasing the capacity within hospital eye services. COGS patients have a lower rate of visual field deterioration compared to AGC patients. Effective communication between community and tertiary schemes is essential to facilitate transfer of patients requiring further hospital management reliably and efficiently, with the potential for low-risk patients to be followed safely in the community.

Abstract
OBJECTIVE The aim of the study was to evaluate safety and efficacy of topically administered 0.02% netarsudil-0.005% latanoprost fixed-dose combination (FDC) (Rocklatan™; Aerie Pharmaceutical) in normal and glaucomatous dogs with ADAMTS10-open-angle glaucoma (ADAMTS10-OAG). ANIMALS STUDIED Five normal and five glaucomatous beagle dogs with ADAMTS10-OAG were the study animals. PROCEDURES In each dog, left (OS) or right eye (OD) was randomly selected for netarsudil-latanoprost FDC treatment. Contralateral eyes served as latanoprost-treated controls. The study was divided into four consecutive study periods: following a 4-day baseline period, two sequential 8-day study periods followed with once daily (q24h) and twice daily (q12h) treatments and ending with a washout period. Efficacy was measured by diurnal intraocular pressure (IOP) and pupil diameter. Safety was assessed by routine ophthalmic examination, gonioscopy, and pachymetry. Differences in least square means of quantitative outcome measures were compared between FDC and latanoprost treatments by using the linear Gaussian model. RESULTS Baseline IOPs were 13.6 ± 0.7 mmHg (mean ± SEM) in normal and 28.3 ± 1.4 mmHg in OAG-affected dogs. There was a significant decrease in mean diurnal IOP following FDC administration in both normal (q24h: -2.1 mmHg; q12h: -4.1 mmHg) and glaucomatous dogs (q24h: -14.2 mmHg; q12h: -17.7 mmHg; p < .0001). There was no significant difference in the treatment effect when comparing FDC to latanoprost. Both FDC and latanoprost administration resulted in similarly significant pupil constriction (p < .0001). The FDC administration was well-tolerated but resulted in conjunctival hyperemia. CONCLUSIONS Once or twice daily administration of netarsudil-latanoprost FDC (Rocklatan™) and latanoprost was equally effective in lowering IOP in normal and OAG-affected dogs. There was no netarsudil-related added treatment effect.

Abstract
OBJECTIVE Assess the real-world efficacy of netarsudil, either as monotherapy or concomitant therapy, in patients with open-angle glaucoma (OAG) or ocular hypertension (OHT) requiring modification of intraocular pressure (IOP)-lowering treatment. METHODS Multicenter, prospective, interventional, open-label, Phase 4 study, clinical trial registration number: NCT03808688. Netarsudil ophthalmic solution 0.02% was prescribed at the recommended once-daily dosage, with treatment regimens determined by the investigators. Netarsudil could be used alone or in combination with other IOP-lowering medications, consistent with standard clinical practice. Primary efficacy endpoint: percentage reduction from baseline IOP at week 12. RESULTS Among 261 enrolled patients, 242 received ≥1 netarsudil dose and had ≥1 follow-up IOP measurement (efficacy population). Mean IOP in patients who were treatment-naïve at baseline and using netarsudil as monotherapy (n = 24) decreased by 16.9%. Netarsudil monotherapy was comparable in efficacy to prior therapy across subgroups, and those who replaced prostaglandin analog (n = 57) monotherapy demonstrated reduction of 2.5% from prostaglandin analog-treated baseline values. Among patients who used netarsudil as concomitant therapy (n = 151), reductions in mean IOP (± standard deviation) to week 12 were seen across subgroups who added netarsudil to a single agent (4.3 ± 2.88 mmHg; 20.5%) or ≥2 classes of concomitant therapy (4.5 ± 4.08 mmHg; 20.9%) and who used netarsudil to replace ≥1 other drug classes (0.4 ± 2.47 mmHg; 1.7%). Of 260 netarsudil-treated patients, 41 (15.8%) discontinued, including 29 (11.2%) due to adverse events. CONCLUSIONS In the real-world treatment of patients with OAG or OHT, netarsudil consistently maintained IOP control when it replaced previous IOP-lowering therapies and provided additional IOP-lowering efficacy when added to other treatments.

Abstract
BACKGROUND Vision impairment remains a major health problem worldwide. Elevated intraocular pressure is a prime risk factor for blindness in the elderly. Netarsudil is a Rho-associated protein kinase (ROCK) inhibitor, which also inhibits norepinephrine transport. This narrative review summarizes the properties and clinical significance of netarsudil, a promising drug in topical glaucoma therapy. METHODS We searched PubMed, Medline and Scopus databases using relevant keywords to retrieve information on the physicochemical properties, formulation, mechanism of action, clinical pharmacokinetics, dose and toxicity of netarsudil. RESULTS Netarsudil showed promising effects in lowering the elevated intraocular pressure by two mechanisms. The US FDA approved netarsudil for clinical use in 2017 under the trademark of Rhopressa® while European Medicines Agency approved Rhokiinsa® in 2019. This drug is available as a 0.02% ophthalmic solution for once-daily topical application. CONCLUSION The discovery of netarsudil is a breakthrough in the therapy of glaucoma with proven efficacy in a wide range of eye pressures and is well tolerated in cases with ocular hypertension and chronic glaucoma.

Abstract
Glaucoma is the most common form of irreversible blindness in the world. Lowering intraocular pressure (IOP) remains the only clinically established method of treatment to slow the progression of glaucoma. Primary open angle glaucoma is a disease of the optic nerve head and often is associated with changes to the trabecular meshwork that cause a reduction to aqueous humour outflow and an increase in intraocular pressure. Until recently, topical IOP lowering medication has been limited to the mechanisms of action of decreasing aqueous production and/or redirecting outflow to the unconventional uveoscleral outflow pathway. Both of these mechanisms neglect to treat or act on tissue that becomes altered from glaucoma. Latanoprostene-bunod 0.024%, a nitric-oxide donating prostanoid, netarsudil 0.02%, a potent Rho-associated protein kinase (ROCK) inhibitor and norepinephrine transporter inhibitor, and a once daily dosed fixed combination medication with netarsudil 0.02% and latanoprost 0.005% have recently come on the market. This paper will discuss and review the limitations to traditional IOP lowering glaucoma medications as well as the mechanism of actions and clinical efficacy of the new glaucoma medications. It will also discuss how the new class of glaucoma medications might help to overcome some known limitations in treatment and barriers to patient adherence.

Abstract
PURPOSE OF REVIEW To discuss a new class of medication that has recently become available for the treatment of glaucoma; as well as share insights into developments in glaucoma medicine administration which has the potential to revolutionize medical therapy for glaucoma. RECENT FINDINGS Newly available eye drops, netarsudil 0.02% and latanoprostene bunod 0.024%, are improving aqueous outflow through the conventional outflow tract. Other new developments in medical glaucoma are focused on alternative methods for sustained glaucoma medication delivery. SUMMARY Newer medications may be able to extend the duration of medically controlled glaucoma, delaying or possibly eliminating the need of glaucoma surgery for some patients. Alternative methods of delivery for glaucoma medications may be a key factor in improving outcomes with currently available medications.

Abstract
Glaucoma is a neurodegenerative disease characterized by progressive loss of retinal ganglion cells and their axons. Lowering of intraocular pressure (IOP) is currently the only proven treatment strategy for glaucoma. However, some patients show progressive loss of visual field and quality of life despite controlled IOP which indicates that other factors are implicated in glaucoma. Therefore, approaches that could prevent or decrease the rate of progression and do not rely on IOP lowering have gained much attention. Effective neuroprotection has been reported in animal models of glaucoma, but till now, no neuroprotective agents have been clinically approved. The present update provides an overview of currently available IOP-lowering medications. Moreover, potential new treatment targets for IOP-lowering and neuroprotective therapy are discussed. Finally, future trends in glaucoma therapy are addressed, including sustained drug delivery systems and progress toward personalized medicine.

Abstract
INTRODUCTION New open-angle glaucoma (OAG) and ocular hypertension (OHT) therapies that reduce treatment burden and improve outcomes relative to currently available agents are needed. Netarsudil, a novel Rho kinase inhibitor approved by the US Food and Drug Administration, reduces intraocular pressure (IOP) by increasing trabecular outflow. Two phase 3 superiority studies compared a fixed-dose combination (FDC) of netarsudil and the prostaglandin latanoprost with each active component for IOP-lowering efficacy. METHODS Pooled efficacy and safety data were analyzed from MERCURY-1 and -2 studies in patients with OAG or OHT. Patients instilled one drop of netarsudil (0.02%)/latanoprost (0.005%) FDC (n = 483), netarsudil (0.02%, n = 499), or latanoprost (0.005%, n = 486) into each eye once-daily between 20:00 and 22:00. IOP was measured at 08:00, 10:00, and 16:00 at weeks 2, 6, and the primary endpoint at month 3. RESULTS Baseline mean diurnal IOP was 23.6, 23.6, and 23.5 mmHg in netarsudil/latanoprost FDC, netarsudil, and latanoprost groups, respectively. Mean diurnal IOP in each group was 15.3, 18.1, and 17.5 mmHg at week 2, 15.7, 18.4, and 17.4 mmHg at week 6, and 15.8, 18.4, and 17.3 mmHg at week 12. The netarsudil/latanoprost FDC met criteria for superiority compared with each active component (p < 0.0001 for all nine time points). At month 3, among patients randomized to netarsudil/latanoprost FDC or latanoprost, 58.4% vs 37.3% (p < 0.0001) achieved IOP ≤ 16 mmHg. Among patients randomized to netarsudil/latanoprost FDC or netarsudil or latanoprost, 30.9% vs 5.9% (p < 0.0001) vs 8.5% (p < 0.0001) achieved at least a 40% reduction from baseline in mean diurnal IOP. Pooled safety results were consistent with individual MERCURY studies. CONCLUSION Once-daily netarsudil/latanoprost FDC produced statistically significant and clinically relevant reductions in mean IOP that were statistically superior to IOP reductions achieved by netarsudil and latanoprost monotherapy. Results of the pooled efficacy and safety analyses were consistent with the individual studies. TRIAL REGISTRATION ClinicalTrials.gov identifiers, NCT02558400 and NCT02674854.

Abstract
INTRODUCTION To describe the changes in endothelial cell density (ECD), the coefficient of variation (CV), the percentage of hexagonal cells (%HEX), and central corneal thickness (CCT) following 3 months of therapy with netarsudil 0.02%/latanoprost 0.005% fixed combination, and to compare these changes with those seen with netarsudil 0.02% or latanoprost 0.005% in eyes with ocular hypertension or open-angle glaucoma. METHODS A subset of subjects enrolled in a Phase 3 evaluation of the intraocular pressure-lowering efficacy and safety of netarsudil 0.02%/latanoprost 0.005% fixed combination once daily (QD) versus each of its individual components underwent corneal endothelial cell imaging by specular microscopy and ultrasound pachymetry at baseline and following 3 months of therapy. Images were evaluated in masked fashion at an independent reading center. Changes from baseline to 3 months in ECD, CV, %HEX, and CCT were compared between treatment groups. RESULTS Data from 415 subjects obtained at both baseline and Month 3 were included in this post hoc analysis. Changes from baseline to Month 3 in ECD, CV, and %HEX were clinically insignificant in all three groups, and the changes in the netarsudil/latanoprost fixed combination group demonstrated no statistical difference from those seen in the netarsudil and latanoprost groups. Mean CCT decreased more in the fixed combination group (- 6.4 µm) than in either the netarsudil group (- 3.3 µm, p = 0.0248) or the latanoprost group (- 1.2 µm, p < 0.0001). CONCLUSIONS Netarsudil 0.2%/latanoprost 0.005% fixed combination QD for 3 months in eyes with ocular hypertension or open-angle glaucoma had no clinically significant effects on endothelial cell density or morphology. The significant decrease in CCT in the fixed combination group compared to the two individual component groups may indicate that the potential effects of each drug on CCT are additive, although the magnitude of the observed effects is likely of negligible clinical significance.

Abstract
Reduction of intraocular pressure is the only proven method to treat glaucoma. Initial treatment of glaucoma commonly involves using anti-glaucoma medications either as monotherapy or combination therapy. Studies on aqueous humour dynamics have contributed to our understanding of aqueous outflow mechanisms that have led to the discovery of new drugs. Three new drugs (latanoprostene bunod 0.24%, netarsudil 0.02%, and fixed combination netarsudil 0.02% -latanoprost 0.005%) have been introduced recently in the market with novel mechanisms of action. Latanoprostene bunod 0.024% is a nitric oxide-donating prostaglandin F2α analogue which increases the aqueous outflow both by uveoscleral and trabecular pathways. Netarsudil 0.02% is a potent Rho kinase/norepinephrine transporter inhibitor acting by increasing the trabecular outflow, decreasing the aqueous production, and possibly decreasing the episcleral venous pressure. This review highlights the role of these drugs in the management of glaucoma, with an overview of the major clinical trials on their efficacy, safety, and tolerability.
