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., (Copyright © 2019 The Author(s).

Purpose: To compare the intraocular pressure (IOP)-lowering efficacy and safety of netarsudil once daily (QD) and timolol twice daily (BID)., Design: Double-masked, randomized, phase 3, noninferiority study., Methods: Patients with open-angle glaucoma or ocular hypertension (unmedicated baseline IOP >20 to <30 mm Hg at 8:00 AM) were randomized to netarsudil ophthalmic solution 0.02% QD (PM) or timolol ophthalmic solution 0.5% BID. The primary endpoint was mean IOP at 8:00 AM, 10:00 AM, and 4:00 PM at week 2, week 6, and month 3 in patients with baseline IOP <25 mm Hg (per-protocol population). Safety was recorded over the 6-month treatment period., Results: A total of 186 patients from each treatment arm were included in the primary efficacy analysis. Netarsudil QD met the criteria for noninferiority to timolol BID. Mean treated IOP ranged from 16.3 to 17.9 mm Hg for netarsudil and 16.7 to 17.6 for timolol, with mean reductions from baseline of 3.9 to 4.7 mm Hg and 3.8 to 5.2 mm Hg, respectively. In prespecified secondary analyses, netarsudil demonstrated noninferiority to timolol in patients with baseline IOP <27 mm Hg and <30 mm Hg. The IOP-lowering effects of netarsudil were sustained over 6 months of treatment. No treatment-related serious adverse event (AE) was reported for either study drug. However, statistically significant reductions in mean heart rate were recorded at all study visits for the timolol group. The most frequent ocular AE among netarsudil-treated patients was conjunctival hyperemia (47.9%), which was predominately mild., Conclusions: Netarsudil QD (PM), a first-in-class IOP-lowering medication, was noninferior to timolol BID and was associated with tolerable ocular AEs., (Copyright © 2019 The Author(s).

Purpose: To evaluate netarsudil 0.02% ophthalmic solution in patients with open-angle glaucoma (OAG) and ocular hypertension (OHT)., Design: Double-masked, randomized, multicenter, parallel-group, noninferiority clinical study., Methods: After a washout of all prestudy ocular hypotensive medications, 756 eligible patients with elevated IOP were randomized to receive netarsudil 0.02% once a day (q.d.) (251); netarsudil 0.02% twice a day (b.i.d.) (254); or timolol 0.5% b.i.d. (251) for 12 months, as well as a noninterventional Corneal Observation Study (COS) for patients manifesting cornea verticillata., Results: On treatment, mean IOP at 8:00 AM decreased from a baseline IOP of 22.5-22.6 mm Hg to 17.9-18.8 mm Hg, 17.2-18.0 mm Hg, and 17.5-17.9 mm Hg for netarsudil q.d., netarsudil b.i.d., and timolol, respectively, over 12 months. The most frequently reported adverse events (AEs) were ocular, with the most frequent ocular AE being conjunctival hyperemia, with an incidence of 61%, 66%, and 14%, respectively. The next most frequent AEs were corneal deposits (corneal verticillata), with an incidence of 26%, 25%, and 1%, respectively, and conjunctival hemorrhage (typically petechial), with an incidence of 20%, 19%, and 1%, respectively. All 3 AEs were generally scored as mild, with conjunctival hyperemia and/or hemorrhage appearing sporadically during the study. In the observational follow-up component of this study, there was no clinically meaningful impact of corneal verticillata on visual function in affected patients., Conclusions: In this randomized, double-masked trial, once-daily dosing of netarsudil 0.02% was effective, consistently lowering IOP through 12 months, and was tolerated by the majority of patients., (Copyright © 2019 The Authors.

Purpose: To evaluate the efficacy and ocular and systemic safety of netarsudil 0.02% ophthalmic solution, a rho-kinase inhibitor and norepinephrine transporter inhibitor, in patients with open-angle glaucoma and ocular hypertension., Design: Double-masked, randomized noninferiority clinical trials: Rho Kinase Elevated IOP Treatment Trial 1 and 2 (ROCKET-1 and ROCKET-2)., Methods: After a washout of all pre-study ocular hypotensive medications, eligible patients were randomized to receive netarsudil 0.02% once daily (q.d.), timolol 0.5% twice a day (b.i.d.), and (ROCKET-2 only) netarsudil 0.02% b.i.d. Data through 3 months from both studies are provided in this report., Results: Enrolled into the 2 studies were 1167 patients. Treatment with netarsudil q.d. produced clinically and statistically significant reductions from baseline intraocular pressure (P < .001), and was noninferior to timolol in the per-protocol population with maximum baseline IOP < 25 mm Hg in both studies (ROCKET-2, primary outcome measure and population, ROCKET-1, post hoc outcome measure). Netarsudil b.i.d. was also noninferior to timolol (ROCKET-2). The most frequent adverse event was conjunctival hyperemia, the incidence of which ranged from 50% (126/251, ROCKET-2) to 53% (108/203, ROCKET-1) for netarsudil q.d., 59% (149/253, ROCKET-2) for netarsudil b.i.d., and 8% (17/208, ROCKET-1) to 11% (27/251, ROCKET-2) for timolol (P < .0001 for netarsudil vs timolol)., Conclusions: In 2 large, randomized, double-masked trials reported here, once-daily dosing of netarsudil 0.02% was found to be effective and well tolerated for the treatment of patients with ocular hypertension and open-angle glaucoma. The novel pharmacology and aqueous humor dynamic effects of this molecule suggest it may be a useful addition to the armamentarium of ocular hypotensive medications., (Copyright © 2017 The Authors.
