Pooled Efficacy and Safety Profile of Netarsudil Ophthalmic Solution 0.02% in Patients With Open-angle Glaucoma or Ocular Hypertension.

ABSTRACT: PRECIS:In pooled phase III analyses, once-daily netarsudil 0.02% resulted in intraocular pressure (IOP) reduction that was noninferior to twice-daily timolol 0.5%, with minimal treatment-related serious or systemic adverse events (AEs). Ocular AEs were generally tolerable. PURPOSE:The purpose of this study was to assess the efficacy and safety of the Rho kinase inhibitor netarsudil in patients with open-angle glaucoma or ocular hypertension. PATIENTS AND METHODS:Pooled analysis of data from the ROCKET-1 to 4 phase III studies of once-daily (PM) netarsudil or twice-daily timolol in patients with open-angle glaucoma or ocular hypertension. The primary efficacy measure 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. RESULTS:In the pooled primary efficacy population (netarsudil, n=494; timolol, n=510), once-daily netarsudil was noninferior to twice-daily timolol at all 9 timepoints through month 3. Mean treated IOP ranged from 16.4 to 18.1?mm?Hg among netarsudil-treated patients and 16.8 to 17.6?mm?Hg among timolol-treated patients. In the pooled safety population (n=839 in each treatment group), treatment-related serious AEs occurred at similar frequencies in each treatment group (netarsudil, 0.1%; timolol, 0%). The most common ocular AE, conjunctival hyperemia (netarsudil, 54.4%; timolol, 10.4%), was graded as mild in 77.6% (354/456) of affected netarsudil-treated patients. CONCLUSIONS:Once-daily netarsudil resulted in IOP lowering that was noninferior to twice-daily timolol, with tolerable ocular AEs that were generally mild and self-resolving. As a first-in-class agent in the United States, with a novel mechanism of action, netarsudil may provide a useful therapeutic option for patients who would benefit from IOP lowering.

Project description:IntroductionNetarsudil 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).MethodsPatients 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.ResultsA 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.ConclusionNetarsudil 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 registrationNCT03844945.

Project description:IntroductionNew 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.MethodsPooled 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.ResultsBaseline 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.ConclusionOnce-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 registrationClinicalTrials.gov identifiers, NCT02558400 and NCT02674854.

Project description:IntroductionPharmacotherapy to lower intraocular pressure (IOP) is a mainstay of treatment aimed at delaying progression of visual field loss in ocular hypertension (OHT) and open-angle glaucoma (OAG), but some topical treatments are less effective in controlling IOP at night. Peak IOP may be related to glaucoma progression and can occur outside office hours. A phase 2 study was conducted to evaluate the IOP-lowering efficacy of netarsudil across the diurnal and nocturnal periods.MethodsThis was a randomized, double-masked, single-center, vehicle-controlled, 9-day study. After washout of any prior ocular hypotensive agents, 12 patients with OHT or OAG underwent baseline IOP assessment at 15:00, 18:00, 21:00, 00:00, 03:00, 06:00, 09:00, and 12:00 h on day 1/day 2. Participants were then randomized in a 2:1 ratio to netarsudil ophthalmic solution 0.02% (n = 8) or vehicle (n = 4) for 7 days of self-administered dosing each evening. IOP was assessed at the same time points on day 8/day 9. All measurements were conducted with a Perkins tonometer in habitual positions by day (seated) and at night (supine).ResultsBaseline mean 24-h IOP was 22.4 mmHg in the netarsudil group and 22.9 mmHg in the vehicle group. Netarsudil was associated with a reduction in mean nocturnal IOP (measurements at 21:00, 00:00, 03:00, 06:00 h) of 3.5 mmHg, which was significant relative to baseline nocturnal IOP (P < 0.001) and the reduction in the vehicle group (0.4 mmHg; P < 0.001 vs. netarsudil). Reduction in mean diurnal IOP with netarsudil (3.5 mmHg) was the same as the nocturnal reduction and statistically significant versus baseline (P < 0.001) and the vehicle group (0.9 mmHg; P < 0.01). The magnitude of IOP reductions with netarsudil was consistent at each time point assessed over the 24-h period. No adverse events were reported.ConclusionNetarsudil exhibited consistent IOP-lowering efficacy over a 24-h period in this short-term study.Trial registrationClinicaltrials.gov identifier: NCT02874846.

Project description:IntroductionFixed-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).MethodsIn 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.ResultsOf 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.ConclusionsThe 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.ClinicaltrialsGov identifierNCT02571712.

Project description:Purpose:TAK-639 is a topical, nine-amino acid, synthetic, C-type natriuretic peptide analog in Phase 1 development for the treatment of ocular hypertension (OHT) and primary open-angle glaucoma (POAG). TAK-639 is postulated to lower intraocular pressure (IOP) through a novel mechanism of action (MOA) that increases trabecular meshwork outflow. We investigated the safety and tolerability of TAK-639 in subjects with OHT or POAG. Methods:This was a phase 1, multicenter, randomized, double-masked, placebo-controlled, single- and multiple-dose escalation study. Subjects (aged 18-90 years) with OHT or POAG were randomized 5:2 to TAK-639 or placebo. Three dose levels were planned (0.1%, 0.3%, 0.6% TAK-639), each with four dosing regimens (QD, BID, TID, QID). Safety measures included treatment-emergent adverse events (TEAEs) and ophthalmologic examinations. Pharmacokinetics and pharmacodynamics (reduction of IOP) were also evaluated. Results:In total, 63 subjects were randomized and received 0.1%, 0.3% and 0.6% TAK-639, as single dose, QD, or BID, and 0.1% and 0.3% TID. The study was terminated before 0.6% TID or QID dosing cohorts were studied; instead, 0.6% BID was repeated in a new cohort. TEAEs were instillation related and of mild-to-moderate intensity. There were no TEAEs leading to premature discontinuation, and no serious TEAEs. The most common treatment-related TEAEs were instillation site pain and transient corneal staining with fluorescein. There were no clinically significant concerns across dose groups for all other safety measures, including drop comfort, best corrected visual acuity, slit-lamp biomicroscopy, and corneal epithelial integrity. Little or no systemic exposure was observed. There was a marginal reduction in IOP in one cohort at the highest dose (0.6%) and regimen (BID) tested, suggesting biological plausibility of targeting the trabecular meshwork through this mechanism. Conclusion:TAK-639 was generally well tolerated up to 0.6% BID. Further non-clinical studies will improve understanding of the MOA and the penetration of TAK-639 to the anterior chamber.
