Abstract
Treatment of ocular diseases presents unique challenges and opportunities for the clinician and for the clinical pharmacologist. Ophthalmic pharmaceuticals, typically given as liquids, require consideration of solubility, physiological pH, and osmolarity, as well as sterility and stability, which in turn requires optimal pharmaceutics. Ocular tissue levels are challenging to obtain in humans, and the clinical pharmacokinetics is typically blood levels, which are primarily related to safety, rather than efficacy. The eye is a closed compartment with multiple physiological barriers with esterases and transporters, but relatively little cytochrome oxidases. Delivery routes include topical, intravitreal, and systemic. Patient dosing involves not only adherence issues common to all chronic diseases, but also performance requirements on eye drop instillation. Therapeutically, ocular diseases and their pharmacological treatments include both those analogous to systemic diseases (e.g., inflammation, infection, and neuronal degeneration) and those unique to the eye (e.g., cataract and myopia).

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.

Abstract
Glaucoma encompasses a group of optic neuropathies characterized by complex and often elusive etiopathology, involvihttng neurodegeneration of the optic nerve in conjunction with abnormal intraocular pressure (IOP). Currently, there is no cure for glaucoma, and treatment strategies primarily aim to halt disease progression by managing IOP. This review delves into the etiopathology, diagnostic methods, and treatment approaches for glaucoma, with a special focus on IOP management. We discuss a range of active pharmaceutical ingredients used in glaucoma therapy, emphasizing their chemical structure, pharmacological action, therapeutic effectiveness, and safety/tolerability profiles. Notably, most of these therapeutic agents are administered as topical formulations, a critical aspect considering patient compliance and drug delivery efficiency. The classes of glaucoma therapeutics covered in this review include prostaglandin analogs, beta blockers, alpha agonists, carbonic anhydrase inhibitors, Rho kinase inhibitors, and miotic (cholinergic) agents. This comprehensive overview highlights the importance of topical administration in glaucoma treatment, offering insights into the current state and future directions of pharmacological management in glaucoma.

Abstract
Glaucoma is a leading cause of irreversible blindness, and early detection and treatment are crucial for preventing vision loss. This review aims to provide an overview of current diagnostic and treatment standards, recent medical and technological advances, and current challenges and future outlook for wearable glaucoma diagnostics and therapeutics. Conventional diagnostic techniques, including the rebound tonometer and Goldmann Applanation Tonometer, provide reliable intraocular pressure (IOP) measurement data at single-interval visits. The Sensimed Triggerfish and other emerging contact lenses provide continuous IOP tracking, which can improve diagnostic IOP monitoring for glaucoma. Conventional therapeutic techniques include eye drops and laser therapies, while emerging drug-eluting contact lenses can solve patient noncompliance with eye medications. Theranostic platforms combine diagnostic and therapeutic capabilities into a single device. Advantages of these platforms include real-time monitoring and personalized medication dosing. While there are many challenges to the development of wearable glaucoma diagnostics and therapeutics, wearable technologies hold great potential for enhancing glaucoma management by providing continuous monitoring, improving medication adherence, and reducing the disease burden on patients and healthcare systems. Further research and development of these technologies will be essential to optimizing patient outcomes.

Abstract
The aim is to study the intraocular pressure (IOP)-lowering effects of additional administration of ripasudil in open-angle glaucoma (OAG) patients including high myopia (HM) and pathological myopia (PM). Study design is retrospective cohort study. We assessed the changes in the mean IOP between the HM eyes (axial length ≧ 26.5 mm 33 eyes) and the non-HM eyes (axial length < 26.5 mm 29 eyes) at 4 and 12 weeks from baseline. We also assessed the IOP changes between the PM eyes (21 eyes) and the non-PM eyes (41 eyes). The significant IOP reduction by the ripasudil administration was observed at 4 weeks in the non-HM eyes and at 12 weeks in HM and non-HM eyes. And the IOP reduction in the HM eyes was significantly less than the non-HM eyes at 4 and 12 weeks. IOP reduction by ripasudil had statistically significant association with the baseline IOP and presence of PM. Furthermore, significant IOP reduction by the ripasudil administration was observed at 4 and 12 weeks in the non-PM eyes, but not in the PM eyes. The additional administration of ripasudil was effective in the HM eyes, but less than non-HM eyes. And the PM may negatively contribute to reducing the IOP by ripasudil.

Abstract
Glaucoma, the leading cause of irreversible blindness worldwide, is a chronic and progressive optic neuropathy characterized by damage to the optic and retinal nerve fiber layers, which can lead to permanent loss of peripheral or central vision. Reduction of intraocular pressure (IOP) is the only known modifiable risk factor for preventing and treating glaucoma. Rho kinase (ROCK) inhibitors are a new class of glaucoma drugs with a novel mechanism of action and good safety profile. They exert neuroprotective effects, act on the trabecular tissue, increase the outflow of aqueous humor, and reduce intraocular pressure. However, they also cause local adverse reactions, including common conjunctival congestion and subconjunctival bleeding; however, most are self-limiting and temporary. Netarsudil (0.02%), a ROCK inhibitor, relaxes the trabecular meshwork, increases the outflow of aqueous humor, reduces scleral venous pressure, and directly decreases IOP. Conjunctival congestion can be reduced if netarsudil is administered at night. The combination of these medications is always more effective than the single drug. Ripasudil (0.4%), another ROCK inhibitor, also lowers IOP; however, conjunctival hyperemia is the most common adverse drug reaction. The purpose of this review is to summarize the effects and adverse reactions of ROCK inhibitors in the experimental trial stage and in clinical treatment in recent years, providing suggestions for future clinical drug use, and research and development to reduce the side effects of these drugs, maximize the potential for reducing IOP, and improve the therapeutic effect.

Abstract
The glaucomas are a group of conditions leading to irreversible sight loss and characterised by progressive loss of retinal ganglion cells. Although not always elevated, intraocular pressure is the only modifiable risk factor demonstrated by large clinical trials. It remains the leading cause of irreversible blindness, but timely treatment to lower intraocular pressure is effective at slowing the rate of vision loss from glaucoma. Methods for lowering intraocular pressure include laser treatments, topical medications, and surgery. Although modern surgical innovations aim to be less invasive, many have been introduced with little supporting evidence from randomised controlled trials. Many cases remain undiagnosed until the advanced stages of disease due to the limitations of screening and poor access to opportunistic case finding. Future research aims to generate evidence for intraocular pressure-independent neuroprotective treatments, personalised treatment through genetic risk profiling, and exploration of potential advanced cellular and gene therapies.

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
INTRODUCTION A clinical trial evaluated ocular hypotensive efficacy and safety of netarsudil 0.02% once daily (QD) relative to ripasudil 0.4% twice daily (BID). METHODS This was a single-masked, randomized, phase 3, superiority study. Japanese patients were randomized to either the netarsudil 0.02% group or the ripasudil 0.4% group in a 1:1 ratio and treated for 4 weeks. The primary efficacy variable was mean diurnal intraocular pressure (IOP) (average of diurnal time points at 09:00, 11:00, and 16:00) at Week 4. RESULTS A total of 245 patients were included in the primary analysis. At Week 4, least squares (LS) mean of diurnal IOP adjusted for baseline was 15.96 and 17.71 mmHg in the netarsudil 0.02% and ripasudil 0.4% groups, respectively, demonstrating the superiority of netarsudil 0.02% QD over ripasudil 0.4% BID by a margin of - 1.74 mmHg (p < 0.0001). Mean reduction from baseline in mean diurnal IOP at Week 4 was 4.65 and 2.98 mmHg, respectively. Adverse events (AEs) occurred less frequently in netarsudil 0.02% than in ripasudil 0.4%, with the incidence of ocular AEs being 59.8% and 66.7%, respectively. The most frequently reported AE was conjunctival hyperemia in both groups, with an incidence of 54.9% and 62.6%, respectively. No serious eye-related AEs were reported. CONCLUSION Netarsudil ophthalmic solution 0.02% dosed QD (p.m.) was well tolerated and more effective in reducing IOP than ripasudil ophthalmic solution 0.4% dosed BID. Netarsudil 0.02% QD may become an important option for the treatment of Japanese patients with primary open-angle glaucoma (POAG) or ocular hypertension (OHT).

Abstract
This review aims to provide a better understanding of the emerging role of mitophagy in glaucomatous neurodegeneration, which is the primary cause of irreversible blindness worldwide. Increasing evidence from genetic and other experimental studies suggests that mitophagy-related genes are implicated in the pathogenesis of glaucoma in various populations. The association between polymorphisms in these genes and increased risk of glaucoma is presented. Reduction in intraocular pressure (IOP) is currently the only modifiable risk factor for glaucoma, while clinical trials highlight the inadequacy of IOP-lowering therapeutic approaches to prevent sight loss in many glaucoma patients. Mitochondrial dysfunction is thought to increase the susceptibility of retinal ganglion cells (RGCs) to other risk factors and is implicated in glaucomatous degeneration. Mitophagy holds a vital role in mitochondrial quality control processes, and the current review explores the mitophagy-related pathways which may be linked to glaucoma and their therapeutic potential.

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.

[PMID: 35904596 DOI: 10.1007/s00417-022-05780-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2022] [Revised: 07/12/2022] [Accepted: 07/19/2022] [Indexed: 01/04/2023] Open
Abstract
PURPOSE To assess real-world effectiveness and tolerability of fixed-dose combination netarsudil 0.02%/latanoprost 0.005% (FCNL) in management of glaucoma patients in a tertiary eye care center. METHODS This retrospective cohort study included glaucoma patients initiated on FCNL from January 2018 to July 2021 with at least 1-month follow-up. Demographic and clinical data were collected at baseline and at follow-up visits through 12 months. Patient-solicited side effects were recorded at each visit. Maximum glaucoma pharmacotherapy was defined as surgery/laser being the next treatment option following an intensive pharmacotherapy regimen, or when pharmacotherapy could not be increased due to allergy/intolerance or all pharmacologic mechanisms already being in use. RESULTS Seventy-nine eyes of 47 patients were included. Mean age was 67.7 ± 14.7 years. Baseline IOP was 18.7 ± 4.9 mmHg; mean change in IOP (∆IOP) each study visit compared to baseline ranged from - 1.6 ± 3.5 to - 4.4 ± 4.1 mmHg (all p < 0.05). The eyes on maximum glaucoma pharmacotherapy (73.4%) had similar ∆IOP compared to those on non-maximal therapy at each visit (p > 0.2 for all). Forty-three (54.4%) eyes were switched from a prostaglandin analog alone, producing a 1-month IOP reduction of - 4.7 ± 3.9 mmHg at 1 month which remained significant at each visit for the 12-month study period (all p < 0.05). Across all study visits, conjunctival hyperemia was documented in 26 (32.9%) eyes. Subjective blurry vision was reported in 22 (27.8%) eyes without significant worsening of visual acuity at any visit (all p > 0.05). Six (7.6%) and 7 (8.9%) eyes required further medical or surgical/laser intervention, respectively. Kaplan-Meier analysis revealed no significant difference in the need for subsequent medical or surgical intervention between those on maximum and non-maximal pharmacotherapy (p > 0.4). CONCLUSION FCNL was well-tolerated and demonstrated a significant and sustained reduction in IOP, even as last-line therapy before incisional or laser surgery in those on maximum glaucoma pharmacotherapy. FCNL is a viable treatment option for glaucomatous eyes before consideration of surgical intervention.

Netarsudil as an Adjunctive Therapy: Efficacy and Factors Contributing to a Favorable IOP-Lowering Effect. J Ophthalmol 2022; 2022:6925027. [PMID: 36620524 PMCID: PMC9822751 DOI: 10.1155/2022/6925027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2022] [Revised: 12/13/2022] [Accepted: 12/15/2022] [Indexed: 12/31/2022] Open
Abstract
Purpose The aim of the study is to assess netarsudil's intraocular pressure (IOP)-lowering potential when prescribed as an adjunctive agent, to examine the effect of baseline IOP on patients' response to netarsudil, and to explore patients' characteristics predictive of pronounced responses to netarsudil. Methods This is a single-center, multiprovider retrospective cohort study set at Massachusetts Eye and Ear. Patients with a diagnosis of glaucoma or ocular hypertension on netarsudil and at least one other hypotensive agent for glaucoma who had at least one month of follow-up were included. Patients with additional procedures or glaucoma medication changes were excluded. The main outcome measures were IOP reduction, Kaplan-Meier survival analyses, netarsudil responder type, and complication rates. Results 236 eyes of 236 patients were included. The mean baseline IOP was 19.06 ± 4.6 mmHg on an average of 4 ocular hypotensive medications. 196 (83.1%) patients experienced IOP reduction at the first follow-up visit of 2.84 ± 0.30 mmHg at 55.66 ± 51.89 days. IOP reduction at the second visit among these patients was 3.01 ± 0.44 mmHg at 133.24 ± 77.63 days. After starting netarsudil, 59% had a sustained response (median duration of 315 days), 25% had a robust response (>20% IOP reduction for at least 80% of visits), and 10% had a super response (>20% and >10 mmHg IOP reduction). Netarsudil was effective as an adjunctive therapy across all baseline IOP categories with greater relative IOP reduction in higher baseline IOP groups. Conclusions Netarsudil is an effective adjunctive glaucoma therapy. IOP reductions between 2 and 3 mmHg are typical, but a minority had more pronounced and sustained effects (>10 mmHg). Further analysis is needed to assess specific demographic and clinical factors predictive of these robust responses.

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.

Effectiveness of Netarsudil versus Brimonidine in Eyes already Being Treated with Glaucoma Medications at a Single Academic Tertiary Care Practice: A Comparative Study. CURRENT THERAPEUTIC RESEARCH 2022; 98:100689. [PMID: 36582193 PMCID: PMC9792385 DOI: 10.1016/j.curtheres.2022.100689] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/31/2022] [Accepted: 11/18/2022] [Indexed: 11/25/2022]
Abstract
Background Rho kinase inhibitors, such as netarsudil, are a relatively new class of medications recently introduced into the market for the treatment of glaucoma, the leading cause of irreversible blindness in the world. Previous clinical trials have studied netarsudil's efficacy when used as a first- or second-line agent but limited studies have investigated its effectiveness in the real world where it is more commonly used as a third, fourth, or fifth agent in combination with other topical medications. Equally important, prior studies have not compared its effectiveness to its peer medications in these settings. Objective To compare intraocular pressure (IOP) lowering after initiation of netarsudil or brimonidine therapy in patients with glaucoma using >2 medications for IOP management. Methods A chart review of 369 eyes from 279 patients followed at a single academic tertiary practice was performed with an institutional review board waiver of consent to compare IOP lowering after prescription of netarsudil (n = 176) versus brimonidine (n = 193) as a third, fourth, or fifth IOP-lowering agent. Patients were identified by querying the electronic medical record for those with a glaucoma-related diagnosis who were prescribed either medication. Five sequential IOP measurements were obtained to determine the mean change in IOP before and after treatment (ΔIOP = mean IOP4,5 - mean IOP1,2,3). A multilevel linear mixed-effects model assessed the influence of medication (independent variable) on ΔIOP (dependent variable). Additional independent variables of interest included the number of glaucoma medications at baseline, age, sex, glaucoma type and severity, race, and pretreatment IOP. Bootstrap analysis was performed to remove sampling bias and confirm mixed-effects model findings. Kaplan-Meier survival analysis evaluated the probability of requiring additional intervention within 3 years following the date of medication prescription. Results The unadjusted mean (SD) ΔIOP for netarsudil and brimonidine was -2.20 (4.11) mm Hg and -2.21 (3.25) mm Hg, respectively (P = 0.484). The adjusted linear mixed-effects models and bootstrap analysis demonstrated that there was no statistical difference in IOP-lowering effectiveness between the medications. Netarsudil and brimonidine failed to adequately control IOP at similar rates with 42% and 47% probabilities of survival respectively by the 3-year follow-up (P = 0.520). Conclusions When escalating pharmacologic therapy, the IOP-lowering effect of netarsudil appeared to be similar to that produced by brimonidine. (Curr Ther Res Clin Exp. 2023; 84:XXX-XXX).

[PMID: 35714908 DOI: 10.1016/j.ogla.2022.06.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2021] [Revised: 06/05/2022] [Accepted: 06/08/2022] [Indexed: 06/15/2023]
Abstract
PURPOSE To investigate the role of netarsudil as an outcome predictor of MicroPulse transscleral laser therapy (MPTLT). DESIGN Retrospective comparative study. SUBJECTS Forty-seven eyes in 33 adult patients with glaucoma with a minimum of 1 month of follow-up after netarsudil treatment and 3 months of follow-up after MPTLT were included. Eyes receiving intraocular pressure (IOP)-lowering procedures in the interim were excluded. INTERVENTION Ophthalmic eyedrops of netarsudil at 0.02%, followed by MPTLT treatment. MAIN OUTCOME MEASURES Correlation of success between netarsudil and MPTLT. Netarsudil success was defined as an IOP reduction ≥ 20% from baseline, whereas MPTLT success was defined as an IOP reduction ≥ 20% without additional IOP-lowering medications. Secondary outcomes included success rates, mean IOP reduction, adverse effects after each treatment, and netarsudil discontinuation rate. RESULTS We found a positive correlation between the netarsudil response and the subsequent MPTLT response (odds ratio, 3.73; 95% confidence interval, 1.05-13.24; P = 0.041). Among netarsudil responders, 73.7% (14/19) of eyes subsequently responded to MPTLT, whereas among netarsudil nonresponders, 42.8% (12/28) of eyes subsequently responded to MPTLT (P = 0.037). From netarsudil, 44.4% of eyes were successful; from MPTLT, 55.3% of eyes were successful. The mean IOP reductions were 2.83 ± 5.74 mmHg from netarsudil and 3.15 ± 6.43 mmHg from MPTLT. Overall, the rate of netarsudil discontinuation was 55.3%. The most common reasons for netarsudil discontinuation were adverse effects (48.9%), followed by high cost (19.1%). The most common adverse effects to netarsudil were conjunctival hyperemia (48.9%) and blurred vision (8.5%). There were no adverse events reported after MPTLT. After MPTLT, 29.8% of eyes required additional IOP-lowering procedures. CONCLUSIONS The netarsudil response may serve as a predictive marker of the MPTLT response, with over 70% of netarsudil responders subsequently responding favorably to MPTLT in this study.

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
Purpose This retrospective chart review of netarsudil (Rhopressa) characterizes intra-ocular pressure (IOP) reduction, drug tolerance, drug cost, and compliance in a tertiary university Midwest clinic in a variety of glaucoma diagnoses on patients prescribed netarsudil 01/2017 to 5/2020. Methods Patient demographics, primary diagnosis, indication for medication, prescription date, prescription fill status, duration of use, discontinuation reason, and number of IOP-lowering medications were noted. Confounding medication changes were excluded from IOP analysis. The IOP difference between the first visit after starting netarsudil and the baseline (mean before starting netarsudil on the stable medication regimen) was calculated. Results A total of 133 patients were prescribed netarsudil (age 69 ± 20 years, 59% females, 79% white, 86% primary glaucoma) as adjunct glaucoma medication (mean medications 3.2 ± 0.9). Indications were lowering IOP (mean baseline IOP 20.0 ± 6 mmHg) and drug regimen simplification. Prescription was not filled by 22/133 subjects because of the cost (68%) and the need for surgery (23%). No demographic factors were associated with prescription fill status. A total of 101 eyes of 76 patients were used for IOP analysis. The mean change in IOP was -0.8 ± 6.4 mmHg, (IOP decrease in 67%, increase or no change in 33% eyes). Netarsudil was discontinued in 52% (50/96) patients; the reasons include surgery for IOP control (42%), allergies (30%), cost (14%), and paradoxical rise in IOP (12%). Conclusion Netarsudil was used as adjunct third or fourth line medication at a glaucoma practice in Midwestern USA. 17% of prescriptions went unfilled; netarsudil was discontinued in 52% of patients. IOP response was variable in this population with severe complex glaucoma.

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.

J Glaucoma 2022; 31:382-391. [PMID: 35394456 PMCID: PMC9148672 DOI: 10.1097/ijg.0000000000002030] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2021] [Accepted: 03/26/2022] [Indexed: 11/26/2022]
Abstract
PRCIS NCX 470 0.042% and 0.065% were statistically superior in intraocular pressure (IOP) lowering to latanoprost 0.005%, and NCX 470 0.021% was noninferior. All NCX 470 concentrations were safe and well tolerated. PURPOSE The purpose of this study was to compare varying concentrations of NCX 470 (a nitric oxide-donating bimatoprost) to latanoprost in a dose-response safety and efficacy trial. PATIENTS AND METHODS Adult patients with bilateral open-angle glaucoma or ocular hypertension were randomized to NCX 470 0.021% (n=111), 0.042% (n=108), 0.065% (n=107), or latanoprost 0.005% (n=107) once daily in the evening. IOP was measured at 8:00 am, 10:00 am, and 4:00 pm at weeks 1, 2, and 4. The primary efficacy endpoint was the reduction from baseline in mean diurnal IOP at week 4. Secondary efficacy endpoints included reductions from baseline in mean diurnal IOP at weeks 1 and 2, and reductions from baseline in time-matched IOP at 8:00 am, 10:00 am, and 4:00 pm at weeks 1, 2, and 4. Adverse events were evaluated. RESULTS All concentrations of NCX 470 resulted in significant reductions of mean diurnal IOP. The 0.042% and 0.065% concentrations were statistically superior to latanoprost 0.005%, and 0.021% was noninferior to latanoprost for change from baseline in mean diurnal IOP at week 4. The 0.065% concentration was also superior to latanoprost by up to 1.4 mm Hg for reduction from baseline at 8:00 am, 10:00 am, and 4:00 pm at week 4. NCX 470 was safe and well tolerated; conjunctival hyperemia was the most frequently reported adverse event. CONCLUSIONS NCX 470 demonstrated dose-dependent reductions in IOP. The 0.042% and 0.065% concentrations demonstrated significantly greater reductions from baseline in mean diurnal IOP than latanoprost 0.005% at week 4, suggesting that higher concentrations may show even greater efficacy.

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
PURPOSE To evaluate ocular hypotensive efficacy and the safety of sovesudil (formally known as PHP-201), a novel Rho-associated protein kinase (ROCK) inhibitor, in patients with normal-tension glaucoma (NTG). DESIGN Multicentre, prospective, double-masked, randomized, placebo-controlled, parallel clinical study. METHODS Patients with NTG (unmedicated baseline IOP ≤ 21 mmHg) were randomized in 3 groups and treated with sovesudil in concentrations of 0.25% and 0.5%, or with a placebo three times daily (TID) for 4 weeks. The primary end-point was the mean diurnal IOP change from the baseline at week 4. Safety was recorded over a 4-week treatment period and the following 2-week observation period. RESULTS A total of 119 patients were included in the primary efficacy analysis. The mean diurnal IOP change from the baseline at week 4 was -1.56 mmHg for the high-dose group, -1.10 mmHg for the low-dose group and -0.65 mmHg for the placebo group. The difference between the high-dose and the placebo groups was -0.91 mmHg (95% confidence intervals: -1.73, -0.09). 0.5% sovesudil TID met the criteria for superiority to the placebo. The most frequent ocular adverse event among sovesudil-treated patients was conjunctival hyperaemia (24.4% for the high-dose and 17.5% for the low-dose group) and predominately classified as mild. CONCLUSIONS Sovesudil 0.25% and 0.5% TID showed statistically significant IOP-lowering effects and 0.5% concentration's IOP-lowering effects met the superiority criteria in comparison with the placebo at week 4. Sovesudil was well tolerated with mild adverse events including relatively low incidence of conjunctival hyperaemia in patients with NTG.

The Dual Effect of Rho-Kinase Inhibition on Trabecular Meshwork Cells Cytoskeleton and Extracellular Matrix in an In Vitro Model of Glaucoma. J Clin Med 2022; 11:jcm11041001. [PMID: 35207274 PMCID: PMC8877133 DOI: 10.3390/jcm11041001] [Citation(s) in RCA: 14] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2021] [Revised: 02/04/2022] [Accepted: 02/11/2022] [Indexed: 02/08/2023] Open
Abstract
The trabecular meshwork (TM) is the main site of drainage of the aqueous humor, and its dysfunction leads to intraocular pressure elevation, which is one of the main risk factors of glaucoma. We aimed to compare the effects on cytoskeleton organization and extracellular matrix (ECM) of latanoprost (LT) and a Rho-kinase inhibitor (ROCKi) on a transforming growth factor beta2 (TGF-β2)-induced glaucoma-like model developed from primary culture of human TM cells (pHTMC). The TGF-β2 stimulated pHTMC were grown and incubated with LT or a ROCKi (Y-27632) for 24 h. The expression of alpha-smooth muscle actin (αSMA) and fibronectin (FN), and phosphorylation of the myosin light chain (MLC-P) and Cofilin (Cofilin-P) were evaluated using immunofluorescence and Western blot. The architectural modifications were studied in a MatrigelTM 3D culture. TGF-β2 increased the expression of αSMA and FN in pHTMC and modified the cytoskeleton with cross-linked actin network formation. LT did not alter the expression of αSMA but decreased FN deposition. The ROCKi decreased TGF-β2-induced αSMA and FN expression, as well as MLC-P and Cofilin-P, and stimulated the cells to recover a basal cytoskeletal arrangement. In the preliminary 3D study, pHTMC organized in a mesh conformation showed the widening of the TM under the effect of Y-27632. By simultaneously modifying the organization of the cytoskeleton and the ECM, with fibronectin deposition and overexpression, TGF-β2 reproduced the trabecular degeneration described in glaucoma. The ROCKi was able to reverse the TGF-β2-induced cytoskeletal and ECM rearrangements. LT loosened the extracellular matrix but had no action on the stress fibers.

Abstract
Purpose This study seeks to evaluate the effectiveness of netarsudil (Rhopressa) in patients with inadequately controlled IOP on otherwise maximally tolerated medical therapy. Methods This is a retrospective study of patients started on netarsudil at Stanford University. Exclusion criteria included glaucoma surgery or laser within 6 months of starting netarsudil and other modifications to the baseline medication regimen within 4 weeks of starting netarsudil. The primary outcome was treatment success, defined as IOP reduction meeting a predetermined target, and no further medication, laser, or surgery recommended subsequent to starting netarsudil. Results Sixty-two eyes were included, and 36 (58%) achieved treatment success at first follow-up. Mean baseline IOP was 19.5 ± 5.6 mmHg on a mean of 3.5 ± 0.7 ocular hypotensive medications. The mean change in IOP from baseline to first follow-up was -3.53 mmHg (-17%). In patients who achieved treatment success, mean IOP change was -5.22 mmHg (-28.0%). Of the eyes with baseline IOP ≤ 20 mmHg, 69% achieved treatment success, compared to only 17% of eyes with baseline IOP ≥ 21 mmHg (P < 0.05). Conclusion Netarsudil is effective in lowering IOP for patients on otherwise maximally tolerated medical therapy, for which glaucoma laser or surgery would have been the only remaining therapeutic options. Treatment success was more likely in eyes with baseline IOP under 20 mmHg.

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
PURPOSE To evaluate the efficacy and safety profile of netarsudil 0.02% ophthalmic solution in a tertiary glaucoma referral center. METHODS This retrospective cohort study included patients with glaucoma initiated on netarsudil 0.02% at a single institution from November 2017 to September 2018. Demographic and clinical data were collected, including intraocular pressure (IOP) and drug side effects at baseline and 1-, 3-, and 6-month follow-up visits. RESULTS A total of 340 eyes of 233 patients were included; mean ± SD patient age was 69.1 ± 12.5 years. One hundred twenty (48%) eyes experienced ≥ 20% decreases in IOP at the 1-month study visit; this effect was maintained through the 6-month visit. IOP-lowering effects in patients using ≥ 3 topical glaucoma medications were similar (all p > 0.1). Eighteen (7.4%) and 7 (2.9%) patients experienced increases in IOP of ≥ 3 and ≥ 5 mmHg, respectively. Across all study visits, conjunctival hyperemia was noted at a rate of 27.6%, and though frequently reported, complaints of blurred vision (31.1%) did not manifest in significant worsening of visual acuity. The rate of drug discontinuation due to insufficient IOP-lowering and side effects was 15.6% and 24.8%, respectively. Twenty-nine (11.4%) and 82 (32.3%) eyes required additional medical and surgical/laser intervention, respectively. CONCLUSION Commonly used as the last-line medical therapy in this case series, netarsudil safely and significantly reduced IOP in patients with glaucoma, even in those using ≥ 3 glaucoma medications. Increases in IOP of ≥ 3 mmHg occurred in a small number of patients. Subjective vision changes and conjunctival hyperemia were the most frequently reported side effects.

Abstract
Glaucoma is the third leading cause of blindness and impairment of vision worldwide, after refractive errors and cataracts. According to the survey, the number of people with glaucoma is more than 76 million, with projections increasing to 112 million by 2040. With the coming of an aging society, the number of people suffering from glaucoma will increase day by day. Glaucoma is a heterogeneous disease characterized by damage to the head of the optic nerve and visual field. High intraocular pressure is a major risk and cause of glaucoma optic neuropathy. Therefore, drug lowering intraocular pressure therapy is still the first-line therapy in clinical practice. Here, the targets, structure-activity relationship, and clinical progress of drugs for the treatment of glaucoma are reviewed.

Abstract
Medical management remains the cornerstone of glaucoma management despite advances in the surgical or laser procedures. After a leap of almost two decades of the advent of prostaglandin analogues, recently a new class of drug, Rho kinase (ROCK) inhibitors, has come to limelight because of their varied therapeutic potential in different clinical conditions of eye, especially glaucoma. Their efficacy of lowering intraocular pressure (IOP) by virtue of an entirely different mechanism of decreasing outflow resistance has ignited a series of clinical trials evaluating their potential as monotherapy or as adjunct to existing antiglaucoma medications, and three of them ripasudil, netarsudil and roclatan have even been approved for clinical use in the recent past. There are evidences suggesting their beneficial effects in glaucoma patients even via non-IOP-dependent mechanisms like neuroprotection by improving blood flow to the optic nerve and increasing ganglion cell survival. They can even act as antifibrotic agents and reduce bleb scarring after glaucoma surgery. Hence, their effective role in glaucomatous optic neuropathy is multifaceted primary being improved drainage through the conventional pathway. On the other hand, certain local adverse effects like conjunctival hyperaemia have been reported in substantial proportion of patients, while some others like blepharitis, subconjunctival haemorrhages and cornea verticillata constitute less common side effects. The purpose of this review is to summarize the discovery, evolution and recent update of clinical trials on Rho kinase inhibitors as antiglaucoma medicine and to delineate their role in existing management protocol.

Abstract
Primary open-angle glaucoma is associated with elevated intraocular pressure (IOP) that damages the optic nerve and leads to gradual vision loss. Several agents that reduce the stiffness of pressure-regulating Schlemm's canal (SC) endothelial cells, in the conventional outflow pathway of the eye, lower IOP in glaucoma patients and are approved for clinical use. However, poor drug penetration and uncontrolled biodistribution limit their efficacy and produce local adverse effects. Compared to other ocular endothelia, FLT4/VEGFR3 is expressed at elevated levels by SC endothelial cells and can be exploited for targeted drug delivery. Here, we validate FLT4 receptors as clinically relevant targets on SC cells from glaucomatous human donors and engineer polymeric self-assembled nanocarriers displaying lipid-anchored targeting ligands that optimally engage this receptor. Targeting constructs were synthesized as lipid-PEGx-peptide, differing in the number of PEG spacer units (x), and were embedded in micelles. We present a novel proteolysis assay for quantifying ligand accessibility that we employ to design and optimize our FLT4-targeting strategy for glaucoma nanotherapy. Peptide accessibility to proteases correlated with receptor-mediated targeting enhancements. Increasing the accessibility of FLT4-binding peptides enhanced nanocarrier uptake by SC cells while simultaneously decreasing the uptake by off-target vascular endothelial cells. Using a paired longitudinal IOP study in vivo, we show that this enhanced targeting of SC cells translates to IOP reductions that are sustained for a significantly longer time as compared to controls. Confocal microscopy of murine anterior segment tissue confirmed nanocarrier localization to SC within 1 h after intracameral administration. This work demonstrates that steric effects between surface-displayed ligands and PEG coronas significantly impact the targeting performance of synthetic nanocarriers across multiple biological scales. Minimizing the obstruction of modular targeting ligands by PEG measurably improved the efficacy of glaucoma nanotherapy and is an important consideration for engineering PEGylated nanocarriers for targeted drug delivery.

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
PURPOSE To evaluate the effectiveness of netarsudil in combination with other ocular hypotensive agents in patients with open-angle glaucoma (OAG) or ocular hypertension (OHT). DESIGN Retrospective cohort study. PARTICIPANTS All patients with OAG or OHT with netarsudil added to a regimen of at least 1 other ocular hypotensive agent between March 2018 and March 2019. METHODS Subjects with at least 2 baseline intraocular pressure (IOP) measurements on the same medication regimen before initiation of netarsudil were included. Subjects were excluded if they experienced other changes in their ocular hypotensive medication regimen. MAIN OUTCOME MEASURES Change in IOP after initiation of netarsudil was assessed using linear mixed-effect models. Kaplan-Meier survival analysis was used to evaluate the time to discontinuation of netarsudil for any reason. RESULTS Netarsudil was prescribed for 191 eyes of 138 patients. All of these subjects were included in the analysis of adverse effects. Twelve subjects discontinued netarsudil before the first follow-up visit because of adverse effects, leaving 175 eyes of 126 patients with at least 1 follow-up visit while using netarsudil included in the effectiveness analysis. The mean baseline IOP ± standard deviation was 17.1 ± 5.2 mmHg on a median of 2 ocular hypotensive medications. Including all observations on the same medication regimen after the addition of netarsudil, the mean IOP was 15.0 ± 4.5 mmHg, with a mean reduction of 2.2 mmHg (P < 0.001). A reduction in IOP was observed in eyes on 1 (2.0 mmHg, P < 0.001), 2 (1.0 mmHg, P = 0.12), 3 (3.0 mmHg, P < 0.001), and 4 (2.9 mmHg, P = 0.002) medications at baseline. A sustained ≥ 20% IOP reduction was observed in 16.2% of 123 eyes with at least 2 observations on treatment with netarsudil. Of the 138 subjects who were treated with netarsudil, 26.8% discontinued it because of adverse effects. The median time to discontinuation of netarsudil for any reason was 88 days. CONCLUSIONS This study demonstrates a modest reduction in IOP is achievable with netarsudil in patients with OAG or OHT who are taking as many as 4 ocular hypotensive medications. The incidence of discontinuation due to adverse effects or inadequate efficacy was high. Supplemental material available atwww.aaojournal.org.

Abstract
INTRODUCTION Netarsudil reduces intraocular pressure (IOP) by increasing aqueous outflow through the trabecular meshwork (TM) pathway and decreasing episcleral venous pressure. The primary objective of this phase 2 study was to evaluate ocular hypotensive efficacy and safety of three netarsudil concentrations (0.01%, 0.02%, and 0.04%) relative to its placebo over 4 weeks in Japanese patients with primary open-angle glaucoma (POAG) or ocular hypertension (OHT). METHODS Patients were randomized to one of four treatment arms, netarsudil ophthalmic solution 0.01%, 0.02%, 0.04%, or placebo, and treated once-daily (QD) in the evening (P.M.) for 4 weeks. The primary efficacy variable was mean diurnal IOP (average of diurnal time points at 9 A.M., 11 A.M., and 4 P.M.) at week 4. RESULTS A total of 215 patients were randomized and 207 (96.3%) completed the study. The mean of mean diurnal IOP at baseline ranged from 20.28 to 21.14 mmHg across groups. At week 4, least squares (LS) mean of mean diurnal IOP adjusted for baseline was 16.53, 15.82, 16.06, and 18.94 mmHg in the netarsudil 0.01%, 0.02%, 0.04%, and placebo groups, respectively, demonstrating the superiority of netarsudil (all concentrations) over placebo. At week 4, mean reduction (mean percentage reduction) from baseline in mean diurnal IOP was 4.10 (19.8%), 4.80 (23.5%), 4.81 (23.8%), and 1.73 mmHg (8.2%), respectively, demonstrating statistically significant reductions (p < 0.0001) in all netarsudil concentrations over placebo. Adverse events (AEs) occurred in a concentration-dependent manner, and the incidence of ocular AEs was 34.5%, 42.6%, 68.6%, and 9.1% in the netarsudil 0.01%, 0.02%, 0.04%, and placebo groups, respectively. The most frequently reported AE was conjunctival hyperemia, with an incidence of 23.6%, 37.0%, 56.9%, and 1.8%, respectively. No serious AEs were reported. CONCLUSION Netarsudil ophthalmic solutions 0.01%, 0.02%, and 0.04% dosed QD (P.M.) demonstrated superiority to placebo in terms of hypotensive effectiveness at week 4 and were found to be safe and generally well tolerated. Netarsudil 0.02% QD provided an optimal efficacy and safety profile for the treatment of Japanese patients with POAG or OHT. TRIAL REGISTRATION NCT03844945.

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
Glaucoma is a neuropathic disease that causes optic nerve damage, loss of retinal ganglion cells (RGCs), and visual field defects. Most glaucoma patients have no early signs or symptoms. Conventional pharmacological glaucoma medications and surgeries that focus on lowering intraocular pressure are not sufficient; RGCs continue to die, and the patient's vision continues to decline. Recent evidence has demonstrated that neuroprotective approaches could be a promising strategy for protecting against glaucoma. In the case of glaucoma, neuroprotection aims to prevent or slow down disease progression by mitigating RGCs death and optic nerve degeneration. Notably, new pharmacologic medications such as antiglaucomatous agents, antibiotics, dietary supplementation, novel neuroprotective molecules, neurotrophic factors, translational methods such as gene therapy and cell therapy, and electrical stimulation-based physiotherapy are emerging to attenuate the death of RGCs, or to make RGCs resilient to attacks. Understanding the roles of these interventions in RGC protection may offer benefits over traditional pharmacological medications and surgeries. In this review, we summarize the recent neuroprotective strategy for glaucoma, both in clinical trials and in laboratory research.

Abstract
Glaucoma, being asymptomatic for relatively late stage, is recognized as a worldwide cause of irreversible vision loss. The eye is an impervious organ that exhibits natural anatomical and physiological barriers which renders the design of an efficient ocular delivery system a formidable task and challenge scientists to find alternative formulation approaches. In the field of glaucoma treatment, smart delivery systems for targeting have aroused interest in the topical ocular delivery field owing to its potentiality to oppress many treatment challenges associated with many of glaucoma types. The current momentum of nano-pharmaceuticals, in the development of advanced drug delivery systems, hold promises for much improved therapies for glaucoma to reduce its impact on vision loss. In this review, a brief about glaucoma; its etiology, predisposing factors and different treatment modalities has been reviewed. The diverse ocular drug delivery systems currently available or under investigations have been presented. Additionally, future foreseeing of new drug delivery systems that may represent potential means for more efficient glaucoma management are overviewed. Finally, a gab-analysis for the required investigation to pave the road for commercialization of ocular novel-delivery systems based on the nano-technology are discussed.

Abstract
Objective: To evaluate netarsudil’s role as first-line therapy for the treatment of open-angle glaucoma (OAG) and ocular hypertension (OHT). Data Sources: A literature search utilizing MEDLINE and CINAHL was performed using netarsudil and AR-13324 as keywords. Studies published from January 1970 to September 2020 were eligible. Study Selection and Data Extraction: For inclusion, articles were required to be published in English and participants enrolled in phase I, II, or III clinical trials. Articles were excluded if netarsudil was coformulated with another medication. Preclinical research, case reports, case series, review articles, citations without an abstract, and newsletters were excluded. Literature Review: The search retrieved 97 unique citations; 90 results were excluded, and 7 studies were included for analysis. Relevance to Patient Care and Clinical Practice: In all, 20 years elapsed between the Food and Drug Administration’s approvals of distinct medications to treat OAG. Existing first-line therapies target the uveoscleral pathway, which is responsible for a small amount of aqueous humor outflow. Rho kinase inhibitors target the trabecular pathway, which is responsible for 90% of aqueous humor outflow; thus, Rho kinase inhibitors may significantly reduce intraocular pressure and improve clinical outcomes for patients with OAG or OHT. Conclusions: Evidence demonstrates that netarsudil is inferior to prostaglandin analogues and noninferior to topical β-blockers in the treatment of OAG and OHT. Hyperemia is a common adverse drug reaction, which often resolves after medication discontinuation. Additional phase III clinical trials and evidence-based guidelines are necessary to determine netarsudil’s position in OAG and OHT management.

Abstract
BACKGROUND Glaucoma is a progressive optic neuropathy causing visual impairment and Retinal Ganglionic Cells (RGCs) death gradually posing a need for neuroprotective strategies to minimize the loss of RGCs and visual field. It is recognized as a multifactorial disease, Intraocular Pressure (IOP) being the foremost risk factor. ROCK inhibitors have been probed for various possible indications, such as myocardial ischemia, hypertension, kidney diseases. Their role in neuroprotection and neuronal regeneration has been suggested to be of value in the treatment of neurological diseases, like spinal-cord injury, Alzheimer's disease and multiple sclerosis but recently Rho-associated Kinase inhibitors have been recognized as potential antiglaucoma agents. EVIDENCE SYNTHESIS Rho-Kinase is a serine/threonine kinase with a kinase domain which is constitutively active and is involved in the regulation of smooth muscle contraction and stress fibre formation. Two isoforms of Rho-Kinase, ROCK-I (ROCK β) and ROCK-II (ROCK α) have been identified. ROCK II plays a pathophysiological role in glaucoma and hence the inhibitors of ROCK may be beneficial to ameliorate the vision loss. These inhibitors decrease the intraocular pressure in the glaucomatous eye by increasing the aqueous humour outflow through the trabecular meshwork pathway. They also act as anti-scarring agents and hence prevent post-operative scarring after the glaucoma filtration surgery. Their major role involves axon regeneration by increasing the optic nerve blood flow which may be useful in treating the damaged optic neurons. These drugs act directly on the neurons in the central visual pathway, interrupting the RGC apoptosis and therefore serve as a novel pharmacological approach for glaucoma neuroprotection. CONCLUSION Based on the results of high-throughput screening, several Rho kinase inhibitors have been designed and developed comprising of diverse scaffolds exhibiting Rho kinase inhibitory activity from micromolar to subnanomolar ranges. This diversity in the scaffolds with inhibitory potential against the kinase and their SAR development will be intricated in the present review. Ripasudil is the only Rho kinase inhibitor marketed to date for the treatment of glaucoma. Another ROCK inhibitor AR-13324 has recently passed the clinical trials whereas AMA0076, K115, PG324, Y39983 and RKI-983 are still under trials. In view of this, a detailed and updated account of ROCK II inhibitors as the next generation therapeutic agents for glaucoma will be discussed in this review.

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
The ocular drug discovery field has evidenced significant advancement in the past decade. The FDA approvals of Rhopressa, Vyzulta, and Roclatan for glaucoma, Brolucizumab for wet age-related macular degeneration (wet AMD), Luxturna for retinitis pigmentosa, Dextenza (0.4 mg dexamethasone intracanalicular insert) for ocular inflammation, ReSure sealant to seal corneal incisions, and Lifitegrast for dry eye represent some of the major developments in the field of ocular therapeutics. A literature survey also indicates that gene therapy, stem cell therapy, and target discovery through genomic research represent significant promise as potential strategies to achieve tissue repair or regeneration and to attain therapeutic benefits in ocular diseases. Overall, the emergence of new technologies coupled with first-in-class entries in ophthalmology are highly anticipated to restructure and boost the future trends in the field of ophthalmic drug discovery. This perspective focuses on various aspects of ocular drug discovery and the recent advances therein. Recent medicinal chemistry campaigns along with a brief overview of the structure-activity relationships of the diverse chemical classes and developments in ocular drug delivery (ODD) are presented.

Abstract
Background Rising healthcare costs motivate continued cost-reduction efforts. To help lower costs associated with open-angle glaucoma (OAG), a prevalent, progressive disease with substantial direct and indirect costs, clinicians need to understand the cost-effectiveness of intraocular pressure (IOP)-lowering pharmacotherapies. There is little published information on clinicians’ knowledge and attitudes about cost-effectiveness in glaucoma treatment. Purpose This pilot focus group study aimed to explore clinician attitudes and perspectives around the costs and cost drivers of glaucoma therapy; the implementation of cost-effectiveness decisions; the clinical utility of cost-effectiveness studies; and the cost-effectiveness of available treatments. Methods Six US glaucoma specialists participated in two separate teleconferencing sessions (three participants each), managed by an independent, skilled moderator (also a glaucoma specialist) using a discussion guide. Participants reviewed recent publications (n=25) on health economics outcomes research in glaucoma prior to the sessions. Results Participants demonstrated a clear understanding of the economic burden of glaucoma therapy and identified medications, diagnostics, office visits, and treatment changes as key cost drivers. They considered cost-effectiveness an appropriate component of treatment decision-making but identified the need for additional data to inform these decisions. Participants indicated that there were only a few recent studies on health economics outcomes in glaucoma which evaluate parameters important to patient care, such as quality of life and medication adherence, and that longitudinal data were scant. In addition to efficacy, participants felt patient adherence and side-effect profile should be included in economic evaluations of glaucoma pharmacotherapy. Recently approved medications were evaluated in this context. Conclusion Clinicians deem treatment decisions based on cost-effectiveness data as clinically appropriate. Newer IOP-lowering therapies with potentially greater efficacy and favorable side-effect and adherence profiles may help optimize cost-effectiveness. Future studies should include: clinicians’ perspectives; lack of commercial bias; analysis of long-term outcomes/costs; more comprehensive parameters; real-world (including quality-of-life) data; and a robust Markov model.

Abstract
A Rho-associated coiled-coil kinase (ROCK) is identified as a critical downstream effector of GTPase RhoA which contains two isoforms, ROCK1 (also known as p160ROCK and ROKβ) and ROCK2 (also known as Rho-kinase and ROKα), the gene of which is placed on chromosomes 18 (18q11.1) and 2 (2p24), respectively. ROCKs have a principal function in the generation of actin-myosin contractility and regulation of actin cytoskeleton dynamics. They represent a chief role in regulating various cellular functions, such as apoptosis, growth, migration, and metabolism through modulation of cytoskeletal actin synthesis, and cellular contraction through phosphorylation of numerous downstream targets. Emerging evidence has indicated that ROCKs present a significant function in cardiac physiology. Of note, dysregulation of ROCKs involves in several cardiac pathological processes like cardiac hypertrophy, cardiac fibrosis, systemic blood pressure disorder, and pulmonary hypertension. Moreover, ROCKs, in addition to their role in regulating renal arteriolar contraction, glomerular blood flow, and filtration, can also play a role in controlling podocytes, tubular cells, and mesangial cell structure and function. Hyperactivity disorder and over-gene expression of Rho/ROCK have been indicated in different cancers. Furthermore, it seems that increasing the expression of mRNA or ROCK protein has an undesirable effect on patient survival and has a positive impact on the progression and worsening of disease prognosis. This review focuses on the physiological and pathological functions of ROCKs with a particular view on its possible value of ROCK inhibitors as a new therapy in cancers and non-cancer diseases.

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.

Abstract
OBJECTIVE To evaluate safety and efficacy of topically administered 0.02% netarsudil ophthalmic solution (Rhopressa™; Aerie Pharmaceutical) in normal and glaucomatous dogs with ADAMTS10-open-angle glaucoma (ADAMTS10-OAG). ANIMALS STUDIED Five normal and 5 glaucomatous Beagle dogs with ADAMTS10-OAG. PROCEDURES In each dog, left or right eye was randomly selected for netarsudil treatment. Contralateral eyes were sham-treated with balanced salt solution (BSS). Following a 1-week baseline period, dogs were treated once daily (q24h) during week 2, and twice daily (q12h) during week 3; week 4 served as 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 netarsudil and BSS sham-treated eyes by linear Gaussian model. RESULTS Baseline IOPs were 18.5 ± 0.5 mm Hg (mean ± SEM) in normal and 27.8 ± 1.0 mm Hg in OAG dogs. Even though mean IOPs were lower in netarsudil- vs sham-treated eyes, the overall differences were neither significant nor clinically relevant, regardless of treatment frequency (q24h-normal: sham 16.4 ± 1.1 mm Hg vs treatment 15.6 ± 1.0 mm Hg; q24hr-OAG: sham 25.8 ± 2.3 mm Hg vs. treatment 25.7 ± 2.4 mm Hg; q12hr-normal: sham 15.4 ± 0.8 mm Hg vs. treatment 14.4 ± 0.8 mm Hg; q12hr-OAG: sham 26.3 ± 1.7 mm Hg vs. treatment 25.4 ± 1.8 mm Hg). Netarsudil administration was well tolerated but resulted in significant, moderate-to-severe conjunctival hyperemia (P < .001). CONCLUSIONS Once or twice daily administration of netarsudil resulted in marginal and clinically irrelevant IOP decreases in normal and OAG-affected dogs. Except for conjunctival hyperemia, the drug was well tolerated.

Abstract
PURPOSE To compare the ocular hypotensive efficacy and safety of a fixed-dose combination (FDC) of the Rho kinase inhibitor netarsudil and latanoprost vs monotherapy with netarsudil or latanoprost. DESIGN Three-month primary endpoint analysis of a randomized, double-masked, phase 3 clinical trial. METHODS Adults with open-angle glaucoma or ocular hypertension (unmedicated intraocular pressure [IOP] >20 and <36 mm Hg at 8:00 AM) were randomized to receive once-daily netarsudil/latanoprost FDC, netarsudil 0.02%, or latanoprost 0.005% for up to 12 months. The primary efficacy endpoint was mean IOP at 8:00 AM, 10:00 AM, and 4:00 PM at week 2, week 6, and month 3. RESULTS Mean treated IOP ranged from 14.8-16.2 mm Hg for netarsudil/latanoprost FDC, 17.2-19.0 mm Hg for netarsudil, and 16.7-17.8 mm Hg for latanoprost. Netarsudil/latanoprost FDC met the criteria for superiority to each active component at all 9 time points (all P < .0001), lowering IOP by an additional 1.8-3.0 mm Hg vs netarsudil and an additional 1.3-2.5 mm Hg vs latanoprost. At month 3, the proportion of patients achieving mean diurnal IOP ≤15 mm Hg was 43.5% for netarsudil/latanoprost FDC, 22.7% for netarsudil, and 24.7% for latanoprost. No treatment-related serious adverse events were reported; treatment-related systemic adverse events were minimal. The most frequent ocular adverse event was conjunctival hyperemia (netarsudil/latanoprost FDC, 53.4%; netarsudil, 41.0%; latanoprost, 14.0%), which led to treatment discontinuation in 7.1% (netarsudil/latanoprost FDC), 4.9% (netarsudil), and 0% (latanoprost) of patients. CONCLUSIONS Once-daily netarsudil/latanoprost FDC demonstrated IOP reductions that were statistically and clinically superior to netarsudil and latanoprost across all 9 time points through month 3, with acceptable ocular safety.
