Bromfenac ophthalmic solution 0.07% dosed once daily for cataract surgery: results of 2 randomized controlled trials.

PURPOSE: To evaluate the efficacy and ocular safety of bromfenac ophthalmic solution 0.07% (Prolensa) dosed once daily for the treatment of ocular inflammation and pain in subjects who underwent cataract surgery with posterior chamber intraocular lens implantation. DESIGN: Two phase 3, randomized, double-masked, placebo-controlled, multicenter clinical trials. PARTICIPANTS: Four hundred forty subjects (440 study eyes: 222 in the bromfenac group and 218 in the placebo group). METHODS: Two phase 3, prospective, randomized, double-masked, placebo-controlled clinical trials were conducted at 39 ophthalmology clinics in the United States. Subjects 18 years of age or older were randomized to receive either bromfenac 0.07% or placebo dosed once daily beginning 1 day before cataract surgery, on the day of surgery, and continuing for 14 days after surgery (for a total of 16 days). Subjects were evaluated on days 1, 3, 8, 15, and 22 after surgery. The primary efficacy end point was cleared ocular inflammation, as measured by the summed ocular inflammation score of zero (anterior chamber cell count = 0 and absence of flare) by day 15. Secondary end points included cleared ocular inflammation at day 15 and the number of subjects who were pain free at day 1. The data from the 2 clinical trials were integrated for analyses. MAIN OUTCOME MEASURES: Summed ocular inflammation score and ocular pain. RESULTS: A significantly higher proportion of subjects treated with bromfenac 0.07% achieved complete clearance of ocular inflammation by day 15 and at day 15 compared with placebo (P < 0.0001). A statistically significantly higher proportion of subjects in the bromfenac 0.07% group were pain free at all study visits compared with those in the placebo group (P < 0.0001). Fewer subjects in the bromfenac group (3.2%) discontinued investigational product early because of a lack of efficacy than in the placebo group (23.9%; P < 0.0001). The incidence of adverse events was significantly lower in the bromfenac 0.07% group compared with the placebo group (P = 0.0041). CONCLUSIONS: Bromfenac ophthalmic solution 0.07% dosed once daily was clinically safe and effective compared with placebo for the treatment of ocular inflammation and pain in subjects who had undergone cataract surgery and may be a beneficial addition to the current standard of care, which commonly includes ophthalmic antibiotics and corticosteroids.

Safety and Efficacy of Twice-Daily Pilocarpine HCl in Presbyopia: The Virgo Phase 3, Randomized, Double-Masked, Controlled Study.

PURPOSE: To evaluate the safety, efficacy, and pharmacokinetics of pilocarpine hydrochloride 1.25% (Pilo hereafter) compared with vehicle when administered bilaterally, twice daily (6 hours apart) for 14 days in participants with presbyopia. DESIGN: Phase 3, randomized (1:1), controlled, double-masked, multicenter study. METHODS: Participants (40-55 years of age) had objective and subjective evidence of presbyopia affecting daily activities with mesopic, high-contrast, binocular distance-corrected near visual acuity (DCNVA) of 20/40 to 20/100. The primary/key secondary endpoint was the proportion of participants gaining ≥3 lines in mesopic/photopic, high-contrast, binocular DCNVA on day 14 (last study visit), hour 9 (3 hours after the second dose), with no more than a 5-letter loss in mesopic/photopic corrected distance visual acuity with the same refractive correction. Key safety measures included treatment-emergent adverse events (TEAEs) and some ocular measurements. Pilocarpine plasma levels were assessed in approximately 10% of enrolled participants. RESULTS: Overall, 230 participants were randomized to Pilo twice daily (N = 114) and vehicle (N = 116). The proportion of participants achieving the primary and key secondary efficacy endpoints was statistically significantly greater with Pilo twice daily than vehicle, with between-treatment differences of 27.3% (95% CI = 17.3, 37.4) and 26.4% (95% CI = 16.8, 36.0), respectively. The most common TEAE was headache, reported in 10 participants (8.8%, Pilo group) and 4 participants (3.4%, vehicle group). Pilocarpine's accumulation index on day 14 was ≤1.11 after the second dose. CONCLUSIONS: Near-vision improvements were statistically greater with Pilo twice daily than with vehicle, without compromising distance acuity. The safety profile of Pilo twice daily was consistent with that of Pilo once daily, and systemic accumulation was minimal, supporting twice daily administration.

A Randomized, Phase 2 Study of 24-h Efficacy and Tolerability of Netarsudil in Ocular Hypertension and Open-Angle Glaucoma.

INTRODUCTION: Pharmacotherapy 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. METHODS: This 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). RESULTS: Baseline 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. CONCLUSION: Netarsudil exhibited consistent IOP-lowering efficacy over a 24-h period in this short-term study. TRIAL REGISTRATION: Clinicaltrials.gov identifier: NCT02874846.

When pressure inside the eye (called intraocular pressure [IOP]) builds up, a patient may develop a condition known as glaucoma, in which damage to the optic nerve and possibly irreversible vision loss occur. Glaucoma can be preceded in some patients by a condition called ocular hypertension (OHT). Patients with OHT and the most common type of glaucoma (open-angle glaucoma [OAG]) should be treated to lower their IOP and decrease the risk for progressive visual loss. Several studies that have evaluated 24-h IOP control have indicated that some eye drops lower IOP less effectively at night than during the day. A pilot study was conducted in 12 patients with OHT or OAG to evaluate netarsudil's IOP lowering effect during the day and at night. After a week of treatment with netarsudil or a similar eye drop that did not contain the active drug, patients who took netarsudil experienced the same decrease in IOP at night as during the day. IOP was statistically lower with netarsudil than with the drug-free comparator both during the day and at night. Although this was a small study in 12 patients, the results are of interest because they suggest that netarsudil might consistently reduce IOP over a 24-h period.

Duration of IOP reduction with travoprost BAK-free solution.

PURPOSE: To compare the duration of action of travoprost ophthalmic solution 0.004% (Travatan Z) formulated without benzalkonium chloride (BAK) to travoprost ophthalmic solution 0.004% formulated with BAK (Travatan). METHODS: This was a prospective, randomized, double-masked study. Patients with open-angle glaucoma or ocular hypertension were randomized to receive 2 weeks of once-daily therapy with travoprost BAK-free or travoprost with BAK. Patients received the last dose of medication on day 13 and then intraocular pressure (IOP) was assessed every 12 hours for 60 hours. Statistical analysis included change in IOP from baseline for each group and comparison of mean IOP between groups. RESULTS: Of the 109 patients enrolled, 106 patients completed the study. Untreated mean baseline IOP at 8 AM was 26.9 mm Hg in the travoprost BAK-free group and 27.1 mm Hg in the travoprost with BAK group. At 12, 24, 36, 48, and 60 hours after the last dose, mean IOP in the travoprost BAK-free group was 18.7, 17.2, 19.5, 18.7, and 20.8 mm Hg, respectively; whereas mean IOP in the travoprost with BAK group was 18.5, 16.8, 19.7, 18.0, and 20.8 mm Hg, respectively. Mean IOP at all time points after the last dose of medication was >6 mm Hg lower than the 8 AM baseline in both groups. Between-group differences were within +/-0.6 mm Hg at all postdose time points. There were no statistically significant differences between the 2 treatment groups at baseline or at any postdose time point. Drug-related side effects were uncommon, mild in intensity, and comparable between groups. CONCLUSIONS: Travoprost without BAK has similar IOP-lowering efficacy and safety compared with travoprost preserved with BAK. Both formulations of travoprost have a prolonged duration of action, with statistically and clinically significant reductions from baseline persisting up to 60 hours after the last dose.

Submicron loteprednol etabonate ophthalmic gel 0.38% for the treatment of inflammation and pain after cataract surgery.

PURPOSE: To assess the safety and efficacy of a 0.38% submicron formulation of loteprednol etabonate (LE) gel for the treatment of postoperative inflammation and pain after cataract surgery. SETTING: Forty-five United States ophthalmology practices. DESIGN: Double-masked vehicle-controlled randomized parallel group study. METHODS: Patients 18 years of age or older with anterior chamber cells grade 2 or higher on day 1 after uncomplicated cataract surgery were randomized to 14 days of treatment with LE gel 2 times a day, LE gel 3 times a day, or vehicle. Hierarchical primary endpoints were the proportion of patients with resolution of anterior chamber cells and grade 0 (no) pain at postoperative day 8. Safety outcomes included adverse events, intraocular pressure (IOP), biomicroscopy, visual acuity, ophthalmoscopy, and tolerability (drop comfort and ocular symptoms). RESULTS: The intent-to-treat population included 514 patients. Significantly more patients in the LE gel 2 times a day and 3 times a day groups compared with the vehicle group had complete resolution of anterior chamber cells (26.9% and 28.7% versus 9.3%) and reported grade 0 pain (73.7% and 73.1% versus 47.7%) on day 8 (P < .001 vs vehicle for all). The safety findings were unremarkable, with 1 patient experiencing an IOP increase of 10 mm Hg or higher while on LE gel. More than 75% of patients in each group reported no drop discomfort. CONCLUSION: In this study, submicron loteprednol etabonate gel 0.38% appeared safe and effective in the treatment of postoperative inflammation and pain whether instilled 2 times or 3 times a day.

Ocular comfort assessment of lifitegrast ophthalmic solution 5.0% in OPUS-3, a Phase III randomized controlled trial.

PURPOSE: To evaluate ocular comfort of lifitegrast ophthalmic solution 5.0% among patients with dry eye disease (DED) in the OPUS-3 trial. METHODS: OPUS-3 was a multicenter, randomized, double-masked, placebo-controlled study. Adults with DED and recent artificial tear use were randomized 1:1 (lifitegrast:placebo) to ophthalmic drops twice daily for 84 days. On days 0 (baseline), 14, 42, and 84, drop comfort score (scale, 0-10; 0 = very comfortable, 10 = very uncomfortable) was measured at 0, 1, 2, and 3 minutes postinstillation. If the score was >3 at 3 minutes, assessment was repeated at 5, 10, and 15 minutes until score ≤3. Ocular treatment-emergent adverse events (TEAEs) were assessed. RESULTS: Overall, 711 participants were randomized (n=357 received lifitegrast; n=354 received placebo). Drop comfort scores for lifitegrast-treated participants improved within 3 minutes of instillation (mean scores on day 84 for both study and fellow eyes: instillation: lifitegrast, 3.4, placebo, 1.0; 3 minutes: lifitegrast, 1.5, placebo, 0.7). The majority (64%-66%) of participants had scores <3 within 3 minutes postinstillation on days 14, 42, and 84. In participants with scores >3 at 3 minutes, the mean score in the lifitegrast group was similar to or better than that in the placebo group at 5, 10, or 15 minutes postinstillation. Lifitegrast appeared to be well tolerated, with ocular TEAEs rarely leading to discontinuation. CONCLUSION: In OPUS-3, lifitegrast appeared to be well tolerated and drop comfort scores approached placebo levels by 3 minutes postinstillation.

Polyquaternium-1-Preserved Travoprost 0.003% or Benzalkonium Chloride-Preserved Travoprost 0.004% for Glaucoma and Ocular Hypertension.

PURPOSE: To demonstrate equivalence of polyquaternium-1-preserved travoprost 0.003% with benzalkonium chloride-preserved travoprost 0.004% in patients with open-angle glaucoma or ocular hypertension. DESIGN: Double-masked, randomized, 2-treatment, equivalence clinical trial. METHODS: setting: Multicenter clinical trial conducted in 60 centers in the United States and Europe. PATIENT POPULATION: Adult patients with open-angle glaucoma or ocular hypertension. One eye per patient was analyzed. INTERVENTION: Patients were randomized 1:1 to receive polyquaternium-1-preserved travoprost 0.003% (n = 442) or benzalkonium chloride-preserved travoprost 0.004% (n = 422) once daily for 3 months. MAIN OUTCOME MEASURES: Mean intraocular pressure (IOP) was assessed at 8 AM, 10 AM, and 4 PM at week 2, week 6, and month 3. Supportive outcomes were mean and percent IOP change, percentage of patients achieving IOP <18 mm Hg or ≥30% IOP reduction, and adverse events. RESULTS: Mean IOP was similar between groups at all study visits (travoprost 0.003% range, 17.5-18.9 mm Hg; travoprost 0.004% range, 17.4-19.0 mm Hg). Mean change (least squares mean differences, -0.1 to 0.3 mm Hg; 95% confidence interval, -0.5 to 0.7 mm Hg) and percentage change (travoprost 0.003%, 28.4%-30.7%; travoprost 0.004%, 28.5%-31.0%) from baseline were comparable. The percentages of patients with IOP <18 mm Hg and ≥30% reduction of IOP were also similar. Hyperemia was the most frequent treatment-related adverse event with both formulations (travoprost 0.003%, 11.8%; travoprost 0.004%, 14.5%). CONCLUSIONS: In patients with open-angle glaucoma or ocular hypertension, polyquaternium-1-preserved travoprost 0.003% solution provided equivalent IOP-lowering efficacy to that of benzalkonium chloride-preserved travoprost 0.004%.

Profile and predictors of normal ganglion cell-inner plexiform layer thickness measured with frequency-domain optical coherence tomography.

PURPOSE: To describe the profile and identify the predictors of the ganglion cell-inner plexiform layer (GCIPL) thickness measured with frequency-domain optical coherence tomography (FD-OCT) in normal eyes. METHODS: Two hundred eighty-two normal subjects underwent macular and optic disc scanning in both eyes with Cirrus high-definition (HD)-OCT (Carl Zeiss Meditec, Dublin, CA). Linear regression analyses were performed to determine the association between GCIPL thickness and age, sex, ethnicity (Europeans, Africans, Hispanics, Asians, and Indians), eye laterality, refraction, intraocular pressure, axial length, central corneal thickness, mean retinal nerve fiber layer (RNFL) thickness, disc and rim areas, cup-to-disc area, vertical and horizontal cup-to-disc diameter ratios, vertical rim thickness, and OCT signal strength. RESULTS: The mean (±SD) age was 46.2 ± 16.9 years (range, 18-84 years). The mean and minimum GCIPL thicknesses (±SD) were 82.1 ± 6.2 and 80.4 ± 6.4 µm, respectively. There were significant differences in GCIPL thickness between macular sectors (P < 0.05), except between the superotemporal and inferonasal sectors (P = 0.63). The superonasal sector had the thickest and the inferior had the thinnest GCIPL. The GCIPL of the superior hemisphere was thicker than that of the inferior, and the nasal sector GCIPL was significantly thicker than the temporal one (P < 0.001). The average GCIPL did not differ between male and female subjects (P = 0.16) after adjustment for axial length and between ethnic groups (P = 0.41) after adjustment for age, axial length, and RNFL thickness. Significant predictors of mean GCIPL thickness were average RNFL thickness (ß = 0.37, P < 0.001), age (ß = -0.083, P < 0.001), axial length (ß = -0.87, P = 0.001), and male sex (ß = -1.62, P = 0.005). CONCLUSIONS: The independent factors associated with thinner GCIPL include thinner RNFL, older age, longer ocular axial length, and being male. Although the magnitude of the effect of age, axial length, and sex are small, these factors should be taken into account when interpreting Cirrus HD-OCT-based GCIPL thickness measurements.

Once daily dosing of bromfenac ophthalmic solution 0.09% for postoperative ocular inflammation and pain.

OBJECTIVE: To evaluate the efficacy and ocular safety of bromfenac ophthalmic solution 0.09% dosed once daily for the treatment of ocular inflammation and pain following cataract extraction with posterior chamber intraocular lens implantation. METHODS: A total of 455 subjects (455 study eyes: 230 bromfenac, 225 placebo) were enrolled in two randomized double-masked, placebo-controlled, clinical trials at 64 ophthalmology clinics in the United States. Subjects were randomized to receive either bromfenac 0.09% or placebo dosed once daily. Dosing began 1 day before cataract surgery (Day -1), continued on day of surgery (Day 0), and for 14 days following surgery. Evaluations were completed on Days 1, 3, 8, 15 and 22. The primary efficacy endpoint was cleared summed ocular inflammation score (SOIS) by Day 15. The secondary efficacy endpoint was the number of subjects who were pain-free at Day 1. RESULTS: The bromfenac 0.09% group was significantly higher compared to the placebo group in the primary endpoint of the proportion of subjects who had cleared ocular inflammation by Day 15 (P < 0.0001). The mean SOIS for the bromfenac 0.09% group was lower than the placebo group at Days 3, 8, 15, and 22 (P < 0.0001). More bromfenac 0.09% subjects were pain free at Days 1, 3, 8, and 15 (P < 0.0001). Fewer subjects in the bromfenac 0.09% group withdrew from the clinical trials due to lack of efficacy at Day 15 (P < 0.0001). Fewer adverse events were reported in the bromfenac 0.09% group than the placebo group. Limitations included advanced age, female predominance, and surgical nuances among cataract surgeons, making cross-trial comparisons difficult. CONCLUSIONS: Bromfenac ophthalmic solution 0.09% dosed once daily is clinically safe and effective for the treatment of ocular inflammation and the reduction of ocular pain associated with cataract surgery.

A study of the safety and efficacy of travoprost 0.004%/timolol 0.5% ophthalmic solution compared to latanoprost 0.005% and timolol 0.5% dosed concomitantly in patients with open-angle glaucoma or ocular hypertension.

BACKGROUND/AIMS: To compare the intraocular pressure (IOP)-lowering efficacy of travoprost 0.004%/timolol 0.5% in fixed combination with the unfixed combination of latanoprost 0.005% and timolol 0.5% in open-angle glaucoma or ocular hypertension patients with IOP levels below 18 mmHg on the unfixed combination of latanoprost 0.005% and timolol 0.5%. METHODS: Following a 30-day open-label run-in with latanoprost QD PM and timolol QD AM, subjects with intraocular pressure below 18 mmHg were randomized to continue concomitant latanoprost QD PM and timolol QD AM or switch to travoprost 0.004%/timolol 0.5% QD AM and vehicle QD PM in masked fashion and were followed for 3 months. The primary efficacy endpoint was mean IOP reduction from baseline. RESULTS: There were no clinically relevant or statistically significant differences in mean IOP, mean IOP change from baseline, or percentage IOP change from baseline between the two treatment groups. Between-group differences in mean IOP were within +/-0.3 mmHg at all time points (p >/= 0.384), and between-group differences in mean IOP change from baseline were within +/-0.4 mmHg at all time points. Overall, 88% of patients whose IOP was less than 18 mmHg on the unfixed combination of latanoprost and timolol remained well controlled on the same regimen in the masked portion of the study, compared with 92% who remained well controlled after switching to travoprost/timolol. CONCLUSION: Travoprost 0.004%/timolol 0.5% administered once daily and concomitant administration of timolol 0.5% and latanoprost 0.005% produce similar maintenance of IOP-lowering effect in patients who were previously well controlled on concomitant administration of latanoprost and timolol. Patients who are well controlled on latanoprost and timolol concomitant therapy can be switched to once-daily therapy with travoprost 0.004%/timolol 0.5% with no expected compromise in the safety and efficacy of their treatment.

Efficacy, safety, and improved tolerability of travoprost BAK-free ophthalmic solution compared with prior prostaglandin therapy.

PURPOSE: To evaluate the efficacy, safety and tolerability of changing to travoprost BAK-free from prior prostaglandin therapy in patients with primary open-angle glaucoma or ocular hypertension. DESIGN: Prospective, multi-center, historical control study. METHODS: Patients treated with latanoprost or bimatoprost who needed alternative therapy due to tolerability issues were enrolled. Patients were surveyed using the Ocular Surface Disease Index (OSDI) to evaluate OSD symptoms prior to changing to travoprost BAK-free dosed once every evening. Patients were re-evaluated 3 months later. RESULTS: In 691 patients, travoprost BAK-free demonstrated improved mean OSDI scores compared to either latanoprost or bimatoprost (p < 0.0001). Patients having any baseline OSD symptoms (n = 235) demonstrated significant improvement after switching to travoprost BAK-free (p < 0.0001). In 70.2% of these patients, symptoms were reduced in severity by at least 1 level. After changing medications to travoprost BAK-free, mean intraocular pressure (IOP) was significantly decreased (p < 0.0001). Overall, 72.4% preferred travoprost BAK-free (p < 0.0001, travoprost BAK-free vs prior therapy). Travoprost BAK-free demonstrated less conjunctival hyperemia than either prior therapy (p < 0.0001). CONCLUSIONS: Patients previously treated with a BAK-preserved prostaglandin analog who are changed to travoprost BAK-free have clinically and statistically significant improvement in their OSD symptoms, decreased hyperemia, and equal or better IOP control.
