Clin Ophthalmol 2024; 18:1751-1760. [PMID: 38919404 PMCID: PMC11197947 DOI: 10.2147/opth.s462672] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2024] [Accepted: 05/13/2024] [Indexed: 06/27/2024] Open
Abstract
Purpose The effectiveness, safety and tolerability of the preservative-free fixed combination of tafluprost and timolol (PF-TTFC) were evaluated over the 24-h in patients with open-angle glaucoma or ocular hypertension showing signs and symptoms of Ocular Surface Disease (OSD) and uncontrolled intraocular pressure (IOP) on prior benzalkonium chloride (BAK) - Latanoprost monotherapy. Methods In this multi-center, prospective, interventional, non-comparative clinical trial, patients treated with BAK-Latanoprost underwent 24-h IOP measurements (8 am, 11 am, 2 pm, 5 pm, 8 pm, 11 pm, 2 am, 5 am) at baseline and after 3 months from switch to PF-TTFC. Mean 24-h IOP and daytime (8 am-8 pm) vs nighttime (11 pm - 5 am) IOP were compared. Changes in OSD signs and symptoms, quality of life (QoL) and in-vivo corneal confocal microscopy (IVCM) were also evaluated. Results Thirty-eight patients were analyzed. The mean 24-h IOP significantly decreased after 3 months from 17.8 mmHg (95% CI: 17.1-18.6) to 15.3 mmHg (95% CI: 14.6-16.1, p < 0.001). IOP was significantly reduced both at daytime (p < 0.001) and nighttime (p < 0.001), with better IOP control at night [-2.9 (95% CI: -3.5 to -2.1) mmHg vs -2.3 (95% CI: -2.9 to -1.6) mmHg]. In 20 patients (52.6%), corneal fluorescein staining improved, whereas in 4 patients (10.5%) it worsened. Hyperemia has improved in 24 (63.3%) patients and worsened in 2 (5.3%). Breakup time, Schirmer test and QoL scores showed no changes. At IVCM, the mean corneal wing-cell size was found significantly decreased (p < 0.005). Conclusion The switch from BAK-Latanoprost to PF-TTFC significantly reduced IOP over the 24-h and improved OSD signs and symptoms.

KOREAN JOURNAL OF OPHTHALMOLOGY 2024; 38:221-226. [PMID: 38665112 PMCID: PMC11175986 DOI: 10.3341/kjo.2024.0021] [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: 02/20/2024] [Revised: 03/13/2024] [Accepted: 04/18/2024] [Indexed: 06/15/2024] Open
Abstract
PURPOSE To assess efficacy, safety, and tolerability of the preservative-free (PF) fixed-dose combination (FC) of tafluprost 0.0015%/timolol 0.5% (PF tafluprost/timolol FC) in treatments-naive patients with primary open-angle glaucoma (POAG). METHODS This was a retrospective, real-world clinical practice setting study that included 107 eyes of 107 subjects with POAG who had never been treated for glaucoma. All subjects were received PF tafluprost/timolol FC once daily. Intraocular pressure (IOP) levels were documented for each eye at the untreated baseline and up to 6 months after the initiation of medical treatment. All adverse events, including ocular and systemic adverse reactions, were recorded. Additionally, the reasons for medication discontinuations were thoroughly documented. RESULTS A total of 32 POAG patients with high-baseline IOP (>21 mmHg) and 75 with normal-baseline IOP were included in the study. The subjects' baseline mean age was 62.4 ± 8.7 years (range, 26.0-85.0 years); among them, 42 were female (39.3%). Mean IOP at baseline for all patients was 18.6 ± 4.3 mmHg. The mean IOP at 6 months was 12.6 ± 4.7 mmHg, representing a significant decrease compared to the baseline (-32%, p < 0.001). In POAG patients with high-baseline IOP, mean IOP was significantly lowered from 28.0 ± 5.7 mmHg at baseline to 18.0 ± 5.5 mmHg (-35%, p < 0.001); in patients with normal-baseline IOP, from 14.6 ± 3.4 mmHg at baseline to 10.3 ± 4.1 mmHg (-29%, p < 0.001). PF tafluprost/timolol FC was well-tolerated and safe. After 6 months, 97.2% of all patients remained on therapy. CONCLUSIONS In this real-world observational study, once-daily treatment with PF tafluprost/timolol FC demonstrated clinically relevant and statistically significant efficacy, as well as safety and good tolerability, in treatment-naive patients diagnosed with POAG.

Abstract
Glaucoma is currently considered one of the leading causes of severe visual impairment and blindness worldwide. Topical medical therapy represents the treatment of choice for many glaucoma patients. Introduction of latanoprost, 25 years ago, with an entirely new mechanism of action from that of the antiglaucoma drugs used up to that time was a very important milestone. Since then, due mainly to their efficacy, limited systemic side effects and once daily dosing, prostaglandin analogues (PGAs) have become as the first-choice treatment for primary open-angle glaucoma. PGAs are in general terms well tolerated, although they are associated with several mild to moderate ocular and periocular adverse events. Among them, conjunctival hyperemia, eyelash changes, eyelid pigmentation, iris pigmentation and hypertrichosis around the eyes are the most prevalent. The objective of this paper is to review the role of PGAs in the treatment of glaucoma over the 25 years since the launch of Latanoprost and their impact on clinical practice outcomes.

Stable Gastric Pentadecapeptide BPC 157-Possible Novel Therapy of Glaucoma and Other Ocular Conditions. Pharmaceuticals (Basel) 2023; 16:1052. [PMID: 37513963 PMCID: PMC10385428 DOI: 10.3390/ph16071052] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Revised: 07/01/2023] [Accepted: 07/20/2023] [Indexed: 07/30/2023] Open
Abstract
Recently, stable gastric pentadecapeptide BPC 157 therapy by activation of collateral pathways counteracted various occlusion/occlusion-like syndromes, vascular, and multiorgan failure, and blood pressure disturbances in rats with permanent major vessel occlusion and similar procedures disabling endothelium function. Thereby, we revealed BPC 157 cytoprotective therapy with strong vascular rescuing capabilities in glaucoma therapy. With these capabilities, BPC 157 therapy can recover glaucomatous rats, normalize intraocular pressure, maintain retinal integrity, recover pupil function, recover retinal ischemia, and corneal injuries (i.e., maintained transparency after complete corneal abrasion, corneal ulceration, and counteracted dry eye after lacrimal gland removal or corneal insensitivity). The most important point is that in glaucomatous rats (three of four episcleral veins cauterized) with high intraocular pressure, all BPC 157 regimens immediately normalized intraocular pressure. BPC 157-treated rats exhibited normal pupil diameter, microscopically well-preserved ganglion cells and optic nerve presentation, normal fundus presentation, nor- mal retinal and choroidal blood vessel presentation, and normal optic nerve presentation. The one episcleral vein rapidly upgraded to accomplish all functions in glaucomatous rats may correspond with occlusion/occlusion-like syndromes of the activated rescuing collateral pathway (azygos vein direct blood flow delivery). Normalized intraocular pressure in glaucomatous rats corresponded to the counteracted intra-cranial (superior sagittal sinus), portal, and caval hypertension, and aortal hypotension in occlusion/occlusion-like syndromes, were all attenuated/eliminated by BPC 157 therapy. Furthermore, given in other eye disturbances (i.e., retinal ischemia), BPC 157 instantly breaks a noxious chain of events, both at an early stage and an already advanced stage. Thus, we further advocate BPC 157 as a therapeutic agent in ocular disease.

Abstract
AIM To investigate the treatment pattern and safety of tafluprost for glaucoma and ocular hypertension (OH) in clinical practice in China. METHODS This post-marketing observational study included patients who received tafluprost to lower intraocular pressure (IOP) within 30d between September 2017 and March 2020 in 20 hospitals in China. Adverse drug reactions (ADRs) during tafluprost treatment and within 30d after the treatment were collected. RESULTS A total of 2544 patients were included in this study, of them 58.5% (1488/2544) had primary open angle glaucoma (POAG), 21.9% (556/2544) had OH and 19.7% (500/2544) used tafluprost for other reasons. Of 359 ADRs occurred in 10.1% (258/2544) patients, and no serious adverse event occurred. The most common ADR was conjunctival hyperemia (128 ADRs in 124 patients, 4.9%). Totally 1670 participants (65.6%) combined tafluprost with carbonic anhydrase inhibitors (CAIs; 37.1%, 620/1670), sympathomimetics (33.5%, 559/1670), β-blockers (33.2%, 555/1670), other prostaglandin analogs (PGAs; 15.6%, 260/1670) and other eye drops (15.1%, 253/1670). The highest incidence of conjunctival hyperemia was noted in patients who received tafluprost in combination with other PGAs (23 ADRs in 23 patients, 8.8%, 23/260) and the lowest was in combination with CAIs (16 ADRs in 16 patients, 2.6%, 16/620). Tafluprost was applied in primary angle-closure glaucoma (41.6%, 208/500), after glaucoma surgery (17.8%, 89/500) and after non-glaucoma surgery (15.8%, 79/500). CONCLUSION Tafluprost is safe for POAG and OH, and tolerable when combined with other eye drops and under various clinical circumstances.

Abstract
INTRODUCTION Elevated intraocular pressure (IOP) is the most important modifiable risk factor for irreversible sight loss in open angle glaucoma (OAG). The topical fixed-dose combination (FC) of preservative-free (PF) tafluprost (0.0015%) and timolol (0.5%) (tafluprost/timolol) is among the second-line IOP-lowering options for OAG and ocular hypertension (OHT). AREAS COVERED PubMed searches identified publications reporting key evidence from randomized controlled trials (RCTs) and real-world studies examining the safety, tolerability and IOP-lowering efficacy of PF tafluprost/timolol FC therapy in OAG/OHT management. EXPERT OPINION Glaucoma patients are more likely to have ocular surface disease and treatment should be individualized so that target response may be achieved while considering tolerability and quality of life, according to European Glaucoma Society guidelines. PF FC therapies, such as PF tafluprost/timolol FC, avoid ocular surface exposure to toxic preservative agents and reduce the required number of treatment administrations. These properties may enhance treatment tolerability and adherence, resulting in improved IOP-lowering efficacy and disease control. Treatment outcomes from RCTs and real-world studies examining PF tafluprost/timolol FC therapy support this hypothesis, with significant IOP reductions and/or improvements in tolerability parameters demonstrated, regardless of the prior topical therapy used and even when switched directly to PF tafluprost/timolol FC treatment (without washout).

Abstract
Topical anti-glaucomatous medications are still the most important measure to lower intraocular pressure. Large number of studies have confirmed that long-term use of anti-glaucomatous eye drops, especially containing benzalkonium chloride, a preservative, can cause or aggravate ocular surface injury. Ocular surface diseases damage the ocular microenvironmental health status, reduce the patients’ compliance with the treatment, and finally affect the treatment result. Therefore, the ocular surface management of patients with glaucoma is very important. This includes the selection of drugs that are better tolerated according to individual conditions, preservative-free formulations, drugs that protect against ocular surface disease, or selecting surgery and laser treatment, to prevent the damage to the ocular surface by topical anti-glaucomatous drugs.

Abstract
OBJECTIVE Analysis and comparison of country-level data from the VISIONARY study, examining treatment outcomes with the topical fixed-dose combination of preservative-free tafluprost (0.0015%) and timolol (0.5%) (PF tafluprost/timolol FC) in adults with open-angle glaucoma (OAG) and ocular hypertension (OHT) who were insufficiently treated with or unable to tolerate either beta-blocker or prostaglandin analogue (PGA) topical monotherapy. METHODS A European, prospective, observational study was conducted in 11 countries. Adults with OAG/OHT were switched to the PF tafluprost/timolol FC from either PGA or beta-blocker topical monotherapy. Statistical analysis examined changes in mean standard deviation (SD) intraocular pressure (IOP) from baseline at Week 4, Week 12 and Month 6. Data were documented for each eye separately at baseline and during follow up visits, with the eye reported to have the higher IOP (mmHg), as measured using Goldmann applanation tonometry, being selected for analysis (study eye). Country-level subanalysis examined outcomes by prior monotherapy, diagnosis and timing of dosing for those countries recruiting ≥20 patients (Country-level Subanalysis Population). Two-sided paired t-test was used to assess significance regarding mean IOP reduction from baseline and a compound symmetry covariance model was used in cross-country comparisons regarding variation in IOP change from baseline. Treatment-related adverse events (AEs) were evaluated. RESULTS Mean (SD) age among patients recruited to the VISIONARY study ranged between 63.9 (11.8) and 72.4 (10.6) years across all countries. The majority of participants (>50%) were female in each country. The Country-level Subanalysis Population included 551 eyes. Mean (SD) IOP was significantly reduced from baseline in each country at Week 4, Week 12 and Month 6 (p < .0001). Mean IOP reduction at Month 6 ranged from 5.0 mmHg (22.6%, Hungary) to 7.8 mmHg (31.8%, Latvia) and varied significantly between countries (p < .001). The greatest reductions were in Latvia and Russia, where baseline IOP was highest. Country-level IOP reductions were significant irrespective of prior monotherapy, diagnosis or dosing time (p < .0001). Most treatment-related AEs occurred in the UK (26 events, 73% mild). One serious AE was reported (Russia, status asthmaticus). Tolerability with PF tafluprost/timolol FC therapy was rated as good/very good by most patients (85.7-100%) in all countries. CONCLUSION Subanalysis of VISIONARY study data revealed significant IOP reductions following a switch to the PF tafluprost/timolol FC from either PGA or beta-blocker topical monotherapy. Cross-country variation was likely due to baseline IOP differences. Within country, outcomes were consistent regardless of diagnosis, dosing or prior monotherapy. Treatment was generally well tolerated.

Abstract
Introduction The VISIONARY study examined the intraocular pressure (IOP)-lowering efficacy and tolerability of the preservative-free fixed-dose combination of tafluprost (0.0015%) and timolol (0.5%) (PF tafluprost/timolol FC) in a real-world setting. The country-level data reported herein comprise the largest and first observational study of PF tafluprost/timolol FC therapy in Italy. Methods An observational, multicenter, prospective study included adult Italian patients with open-angle glaucoma (OAG) or ocular hypertension (OHT) demonstrating insufficient response or poor tolerability with topical prostaglandin analogue (PGA) or beta-blocker monotherapy. Treatment was switched to PF tafluprost/timolol FC therapy at baseline. Primary endpoint was the absolute mean IOP change from baseline at Month 6. Exploratory and safety endpoints included change in IOP at Weeks 4 and 12, ocular signs, symptom severity and reporting of adverse events (AEs). Results Overall, 160 OAG/OHT patients were included. Mean ± standard deviation IOP was reduced from 19.6 ± 3.6 mmHg at baseline to 14.5 ± 2.6 mmHg at Month 6 (reduction of 5.1 ± 3.7 mmHg; 24.1%; p < 0.0001). IOP reduction was also statistically significant at Week 4 (23.1%; p < 0.0001) and Week 12 (24.7%; p < 0.0001). Based on data cutoff values for mean IOP change of ≥20%, ≥25%, ≥30% and ≥35%, respective Month 6 responder rates were 68.1%, 48.7%, 36.2% and 26.9%. Most ocular signs and symptoms were significantly reduced in severity from baseline at Month 6. Two non-serious and mild AEs were reported during the study period, among which, one AE was treatment-related (eyelash growth). Conclusion Italian OAG and OHT patients demonstrated a significant IOP reduction from baseline at Week 4 that was maintained over a 6-month period following a switch from topical PGA or beta-blocker monotherapy to PF tafluprost/timolol FC therapy. Severity of most ocular signs and symptoms was significantly reduced during the study period, and PF tafluprost/timolol FC was generally well tolerated.

Treatment of open-angle glaucoma and ocular hypertension with preservative-free tafluprost/timolol fixed-dose combination therapy: 6 case reports and clinical outcomes. BMC Ophthalmol 2022; 22:152. [PMID: 35366846 PMCID: PMC8977001 DOI: 10.1186/s12886-022-02361-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2021] [Accepted: 03/20/2022] [Indexed: 01/11/2023] Open
Abstract
Abstract
Background
Treatment of open angle glaucoma (OAG) and/or ocular hypertension (OHT) focuses on achievement of target intraocular pressure (IOP), with the objective of slowing disease progression. However, ocular surface health is an important consideration in the optimization of treatment. We report 6 patient cases in which enhanced IOP control was achieved following appropriate management of ocular surface inflammation and a therapeutic switch to the preservative-free (PF) tafluprost (0.0015%)/timolol (0.5%) fixed-dose combination (FC).
Case presentation
Six patient cases, aged 48–74 years, presented with OAG or OHT. Each patient had signs and symptoms of ocular surface disease (OSD). Cases 1–3 were each receiving maximal medical therapy for OAG; regimens comprising prostaglandin analogue (PGA), β-blocker, carbonic anhydrase inhibitor (CAI) and α-2 agonist agents (including treatments containing preservative agent). Cases 1 and 2 reported IOP values ≥23 mmHg in each eye, and wide IOP fluctuations were identified when reviewing patient data concerning case 3 (11–20 mmHg). Maximal therapy was ceased and PF tafluprost/timolol FC was initiated, after which the signs and symptoms of OSD were improved and IOP was reduced (≤18 mmHg for cases 1–3) and stabilized. Cases 4 and 5 were diagnosed with OAG and case 6 had OHT. Each had symptoms and signs of OSD and were treated with a preserved PGA monotherapy (latanoprost 0.005% or bimatoprost 0.03%). At presentation, IOP was 24 mmHg in both eyes (case 4), ≥18 mmHg (case 5) and ≥ 22 mmHg (case 6). Following a switch to the PF tafluprost/timolol FC, OSD symptoms were improved and IOP was 14 mmHg (both eyes; case 4), ≤14 mmHg (case 5) and 16 mmHg (both eyes; case 6).
Conclusions
In addition to IOP-lowering efficacy, approaches to the management of OAG and OHT should consider the impact of treatment tolerability and the susceptibility of these patients to OSD. The presence of ocular surface inflammation appears to be detrimental to adherence and therefore to the effectiveness of topical medications. Addressing OSD through the use of PF FC formations, such as the PF tafluprost/timolol FC, reduces exposure to potentially toxic agents and facilitates improvements in IOP control.

Abstract
Purpose: Data are presented from ophthalmology clinics in Spain participating in the VISIONARY study, examining the effectiveness, tolerability, and safety of the preservative-free tafluprost (0.0015%) and timolol (0.5%) fixed-dose combination (PF tafluprost/timolol FC) in the treatment of OAG and OHT. Methods: An observational, multicenter prospective study examined treatment outcomes following a switch to PF tafluprost/timolol FC in adult OAG/OHT patients demonstrating insufficient response to beta-blocker or prostaglandin analog (PGA) monotherapy. Primary end point was mean change in intraocular pressure (IOP) from baseline at month 6. Changes in the severity of ocular signs and symptoms were also assessed. Results: Overall, 92 patients (51.1% female) were included. Mean (standard deviation) age was 68.3 (12.1) years. Mean IOP was reduced from 21.9 mmHg at baseline to 16.7 mmHg at month 6 (22.3% decrease; P < 0.0001). Significant IOP reductions were observed at weeks 4 and 12 (P < 0.0001). Baseline PGA and beta-blocker users demonstrated mean month 6 IOP reductions of 5.5 mmHg (23.5%; P < 0.001) and 3.5 mmHg (14.6%; P = 0.029), respectively. Severity of conjunctival hyperemia, dry eye, irritation, itching, foreign body sensation, and eye pain was significantly reduced. Three treatment-related adverse events were reported, all were nonserious and mild/moderate in severity. Conclusion: In real-world clinical practice, PF tafluprost/timolol FC treatment provided significant IOP reductions over 6 months and was well tolerated among OAG/OHT patients showing poor response to PGA or beta-blocker monotherapy. IOP-lowering efficacy and improvements in ocular signs and symptoms were evident from week 4 and maintained over the 6-month study period.

Abstract
INTRODUCTION The VISIONARY study demonstrated statistically significant intraocular pressure (IOP) reductions with the preservative-free fixed-dose combination of tafluprost 0.0015% and timolol 0.5% (PF tafluprost/timolol FC) in open-angle glaucoma (OAG) or ocular hypertension (OHT) patients, sub-optimally controlled with topical prostaglandin analogue (PGA) or beta-blocker monotherapy. Current subanalyses have examined these data according to the baseline monotherapy. METHODS A European, prospective, observational study included adults (aged ≥ 18 years) with OAG or OHT, who were switched to the PF tafluprost/timolol FC from PGA or beta-blocker monotherapy. Treatment outcomes were reported according to prior monotherapy subgroup: beta-blocker, preserved latanoprost, PF-latanoprost, bimatoprost, tafluprost, and travoprost. Endpoints included the mean change from baseline regarding IOP, conjunctival hyperemia, and corneal fluorescein staining (CFS) at Week 4 and Week 12, and at Month 6. RESULTS The subanalysis included 577 patients. All prior monotherapy subgroups demonstrated statistically significant IOP reductions from baseline at Week 4, that were maintained through Month 6 (p < 0.001). Mean (SD) IOP change at Month 6 was 6.6 (4.16), 6.3 (4.39), 5.6 (3.67), 4.9 (2.97), 4.6 (4.39), and 4.7 (3.64) mmHg for prior beta-blocker, preserved latanoprost, PF-latanoprost, tafluprost, bimatoprost, and travoprost subgroups, respectively. The largest IOP change was observed in the preserved latanoprost subgroup for each of the ≥ 20%, ≥ 25%, ≥ 30%, and ≥ 35% IOP reduction categories at Month 6, demonstrating respective reductions of 8.06, 9.20, 10.64, and 11.55 mmHg. CFS was significantly reduced at Month 6 in the prior bimatoprost subgroup (p = 0.0013). Conjunctival hyperemia severity was significantly reduced at each study visit for prior preserved latanoprost users (p < 0.001). CONCLUSION PF tafluprost/timolol FC therapy provided statistically and clinically significant IOP reductions from Week 4 over the total 6-month period, in patients with OAG/OHT, regardless of the type of prior PGA or beta-blocker monotherapy used. Conjunctival hyperemia severity and CFS decreased significantly in prior bimatoprost and preserved latanoprost users, respectively.

Abstract
Glaucoma is one of the most common causes of blindness, thus seriously affecting people’s health and quality of life. The topical medical therapy is as the first line treatment in the management of glaucoma since it is inexpensive, convenient, effective, and safe. This review summarizes and compares extensive clinical trials on the topical medications for the treatment of glaucoma, including topical monotherapy agents, topical fixed-combination agents, topical non-fixed combination agents, and their composition, mechanism of action, efficacy, and adverse effects, which will provide reference for optimal choice of clinical medication. Fixed-combination therapeutics offer greater efficacy, reliable security, clinical compliance, and tolerance than non-fixed combination agents and monotherapy agents, which will become a prefer option for the treatment of glaucoma. Meanwhile, we also discuss new trends in the field of new fixed combinations of medications, which may better control IOP and treat glaucoma.

Abstract
Introduction Reducing intraocular pressure (IOP), the only modifiable risk factor for open-angle glaucoma (OAG), is important for the preservation of vision and slowing of disease progression. Preservative-free tafluprost (0.0015%)/timolol (0.5%) fixed combination (PF Taf-T FC) is an approved combination therapy for OAG treatment. The VISIONARY study aimed to evaluate the effectiveness and tolerability of PF Taf-T FC in real-world clinical settings. Here, we present the results from the United Kingdom (UK) and Ireland. Methods This observational, multicentre, European, prospective study recorded data during routine clinic appointments on the use of PF Taf-T FC for the treatment of OAG and ocular hypertension (OHT) in patients whose disease was insufficiently controlled on a prostaglandin analogue (PGA) or beta blocker monotherapy or who did not tolerate these medications. Mean change in IOP, symptom severity, changes in clinical signs, and tolerability were investigated over 6 months. Results Eighty-two patients were recruited in the UK and Ireland. After 6 months of PF Taf-T FC treatment, mean IOP was significantly reduced from 22.0 to 16.2 mmHg in the UK group and from 18.6 to 14.1 mmHg in the Ireland group. In the UK (65 patients), 49 adverse events (AEs) were reported, of which 3 were serious. No AEs were reported in the Ireland group (17 patients). Overall, 91.9% of UK physicians reported PF Taf-T FC treatment to be the same or better than prior medication for improving clinical signs; 90.0% of UK patients reported PF Taf-T FC treatment to have good or very good tolerability. Conclusions Treatment with PF Taf-T FC resulted in significant reductions in mean IOP over 6 months. Patients and physicians reported that treatment was well tolerated. These data demonstrate real-world efficacy of PF Taf-T FC for the treatment of OAG and OHT in routine clinical practice in the UK and Ireland.

Abstract
PURPOSE The aim of this study was to evaluate the effects of 0.0015% preservative-free (PF) tafluprost alone and in combination with 0.5% timolol maleate or 0.5% betaxolol HCl on Schirmer tear test (STT), intraocular pressure (IOP), and pupil diameter (PD) in clinically normal dogs. METHODS Twenty-one healthy adult castrated male cross-bred dogs were used in this study. Dogs were randomly divided into three groups. The first group received one drop of (PF) tafluprost (Taf), in a randomly selected eye. The second group received one drop of (PF) tafluprost plus one drop of timolol maleate (Taf-Tim), and the last group received one drop of (PF) tafluprost plus one drop of betaxolol HCl, (Taf-Bet). In all groups, the fellow eyes were served as control and received one drop of saline as a placebo. IOP, STT, and PD measurements were performed at the baseline and every 30 min for the first 2 h, every 2 h for the next 10 h, and at 24 h and 36 h post-instillation (PI). RESULTS In all groups, significant differences in IOP values were observed between treated and untreated eyes (Taf: p < 0.001, Taf-Tim: p = 0.014, Taf-Bet: p = 0.008). The maximum reduction in mean IOP after unilateral administration of Taf, Taf-Tim, and Taf-Bet was 8.3 mmHg, 10.7 mmHg, and 13 mmHg, respectively. No significant differences in STT values were observed between treated and untreated eyes at any time points. In all groups, significant differences in PD values were observed between treated and untreated eyes in all time points except the baseline and 36 h post-drug instillation (p < 0.001). CONCLUSIONS Tafluprost alone or in combination with timolol and betaxolol was able to reduce intraocular pressure. The greatest effect of the drugs occurred 6 and 8 h PI. The present study revealed that the combination of tafluprost/betaxolol is more potent in decreasing IOP than tafluprost alone or a combination of tafluprost/timolol in healthy dogs.

Abstract
Preservative-free fixed combination of 0.0015% Tafluprost and 0.5% Timolol (PF tafluprost/timolol FC) has demonstrated good antihypertensive effect and patient tolerance in randomized controlled clinical trials. PURPOSE To evaluate efficacy, tolerability, and safety of PF tafluprost/timolol FC in patients with primary open-angle glaucoma (POAG) and ocular hypertension (OH) who couldn't tolerate or gave insufficient response to topical beta-adrenoblockers or prostaglandin analogue monotherapy. MATERIAL AND METHODS The prospective multicenter European VISIONARY study (EUPAS22204) included 87 patients from 7 ophthalmological centers in Russia with mean age of 63.9±11.8. Primary endpoint was mean IOP change at month 6. The patients were monitored for changes in in the severity of ocular signs and symptoms. RESULTS Statistically significant (p<0.0001) reduction of mean IOP from baseline was seen at all study visits: 7.3±5.17 mmHg at week 4, 7.4±5.40 mmHg at week 12, and 7.1±5.10 mmHg at month 6. By month 6, IOP has decreased by 20; 25; 30 and 35% from baseline in 77.0%, 58.9%, 43.7%, and 31.0% of study patients, respectively. Conjunctival hyperemia was significantly reduced at all study visits. Significant reductions in dry eye symptoms (p<0.0010), irritation (p=0.0204) and itching (p=0.0010) were also observed. After 6 months on PF tafluprost/timolol FC, 85.7% of patients described it as easy or very easy to tolerate. CONCLUSION In clinical practice, PF tafluprost/timolol FC provided statistically significant IOP reductions in patients with POAG and OH insufficiently controlled by or intolerant to monotherapy with topical beta-adrenoblockers or a prostaglandin analogue. The highest IOP reduction was seen at week 4 and was maintained over the 6-month study period. There was also a decrease in the severity of symptoms of ocular surface condition.

Introduction A non-interventional, multicenter, European, prospective evaluation of the effectiveness, tolerability, and safety of a topical preservative-free tafluprost (0.0015%) and timolol (0.5%) fixed-dose combination (PF tafluprost/timolol FC) in adults with open-angle glaucoma (OAG) and ocular hypertension (OHT) demonstrating insufficient response to topical beta-receptor blockers or prostaglandin analogue (PGA) monotherapy. Methods Mean intraocular pressure (IOP) change from baseline was measured at study visits following a switch to PF tafluprost/timolol FC. Primary endpoint was absolute mean IOP change at month 6. Change from baseline concerning ocular signs and symptoms was also explored. Results Analyses included 577 patients (59.6% female). Mean age (SD) was 67.8 (11.67) years. Mean (SD) IOP reduction from baseline was significant at all study visits; 5.4 (3.76) mmHg (23.7%) at week 4, 5.9 (3.90) mmHg (25.6%) at week 12, and 5.7 (4.11) mmHg (24.9%) at month 6 (p < 0.0001 for all visits). At month 6, 69.2%, 53.6%, 40.0%, and 25.8% were responders based on ≥ 20%, ≥ 25%, ≥ 30%, and ≥ 35% cutoff values for mean IOP, respectively. Significant reductions were observed concerning corneal fluorescein staining (p < 0.0001), dry eye symptoms, irritation, itching, and foreign body sensation (p < 0.001 for each parameter). Conjunctival hyperemia was significantly reduced at all study visits (p < 0.0001 at each visit). Overall, 69 treatment-related adverse events (AEs) were reported, one of which was serious (status asthmaticus). Most AEs were mild to moderate in severity, and the majority had resolved or were resolving at the end of the study period. Conclusion In clinical practice, PF tafluprost/timolol FC provided statistically and clinically significant IOP reductions in patients with OAG and OHT insufficiently controlled on or intolerant to PGA or beta-receptor blocker monotherapy. The full IOP reduction appeared at week 4 and was maintained over the 6-month study period. Key symptoms of ocular surface health improved.

Abstract
RELEVANCE: The ability of antiglaucoma drugs to improve ocular hemoperfusion is an important aspect of their action. Tafluprost is the first preservative-free prostaglandin analog. The efficacy and safety of tafluprost, as well as tafluprost/timolol fixed combination (FC), were demonstrated in randomized multicenter trials. However, there is no literature on the effect of tafluprost and its FC on the peripapillary and macular blood flow. PURPOSE: To determine the changes of microcirculation in the optic nerve head (ONH), peripapillary retina, and macula in patients with newly diagnosed primary open-angle glaucoma (POAG) under the topical tafluprost and tafluprost/timolol FC treatment. MATERIALS AND METHODS: Optical coherence tomography angiography (OCT-A) was performed in dynamics with an interval of a week in 36 patients (36 eyes) with a newly diagnosed initial stage of POAG: 12 eyes with tafluprost, 12 – tafluprost/timolol FC, and 12 – no topical treatment (the control group). The change in intraocular pressure (IOP), mean ocular perfusion pressure (MOPP) of the eye, and vessel density (VD) inside the ONH (inside disc), as well as in the peripapillary retina and macula, was evaluated by comparing paired repeated observations using the median growth analysis. RESULTS: In the tafluprost group, there were a decrease in IOP by 19.4% and an increase in MOPP by 8.7% from the reference level. In the tafluprost/timolol group, these figures were 43% and 30.1%, respectively. OCT-A values did not change reliably, except for VD inside disc: the median growth of the tafluprost group was 2.28 (P = 0.02) and of the tafluprost/timolol group was 1.82 (P = 0.03). These changes were obtained in 11 of 12 patients in each group under treatment. In control group, all indicators remained unchanged. CONCLUSIONS: A significant increase of MOPP and a decrease of VD in the ONH in patients with initial glaucoma occurred within a week under the topical tafluprost or its FC. This can be explained by the restoration of autoregulation of the ocular blood flow in conditions of pronounced hypotensive effect of the drugs.

Abstract
Glaucoma therapy-related ocular surface disease (OSD) is a serious pathology with a broad spectrum of insidious clinical presentations and complex pathogenesis that undermines long-term glaucoma care. Preservatives, especially benzalkonium chloride (BAK), contained in topical intraocular pressure-lowering medications frequently cause or aggravate OSD in glaucoma. Management of these patients is challenging, and to date often empirical due to the scarcity of controlled long-term clinical trials. Most of the available data are extracted from case series and retrospective analysis. Preservative-free prostaglandins and prostaglandin/timolol fixed combinations are novel options developed to remove the harmful impact of preservatives, especially BAK, upon ocular tissues. Based on what is currently known on the value of preservative-free antiglaucoma therapies it is tempting to speculate how these new therapies may affect the future medical management of all glaucoma patients. This article provides a comprehensive and critical review of the current literature on preservative-free prostaglandins and preservative-free prostaglandin/timolol fixed combinations.

Abstract
Background: The Tafluprost/Timolol Fixed Combination (TTFC) has demonstrated efficacy and safety in reducing Intraocular Pressure (IOP). However, direct comparisons of switching from tafluprost to TTFC are limited. Objective: To investigate the efficacy and safety of switching from tafluprost to TTFC in patients with Primary Open-Angle Glaucoma (POAG). Methods: Thirty-four eyes (34 patients) with POAG that did not achieve adequate IOP reduction on tafluprost were switched to TTFC with no washout period. IOP, systolic/diastolic blood pressure and pulse rate were measured 1 and 3 months later and compared with baseline values. All participants were asked about specific adverse reactions after 1 and 3 months of treatment. Patients also completed a questionnaire about preference and adherence after 1 month of treatment. Results: Mean IOP after 1 and 3 months was significantly lower than at baseline (14.2 ± 2.1 mmHg and 14.1 ± 2.3 mmHg, respectively, vs 16.0 ± 2.0 mmHg, P < 0.0001). Systolic/diastolic blood pressure and pulse rate were not significantly different from baseline after 1 and 3 months. The questionnaire indicated that the frequency of missing a dose was not different before (27.3%) or after (18.2%) switching to TTFC (P = 0.2371). There were five reports of adverse reactions (14.7%), including a corneal epithelium disorder, ocular irritation, skin irritation at the wrist, and chest pain. Two patients (5.9%) withdrew because of adverse reactions. Conclusion: Switching from tafluprost to TTFC achieved IOP control safely and was well accepted by patients.

Abstract
Background Efficacy, tolerability and safety of the novel preservative-free fixed combination of tafluprost 0.0015%/timolol 0.5% (Taptiqom®) were investigated in an observational study in Germany. Objective To assess efficacy, tolerability and safety of the preservative-free fixed combination of tafluprost 0.0015%/timolol 0.5% in a real-life setting. Methods Intraocular pressure (IOP) was recorded for each eye at baseline (any previous therapy or untreated) and 4–16 weeks after changing medical treatment to or initiating treatment with the preservative-free fixed combination of tafluprost 0.0015%/timolol 0.5%. Change in IOP was evaluated over the study period for all patients and for specific pretreatment subgroups. Clinical signs such as conjunctival hyperemia and lid-parallel conjunctival folds (LIPCOF) were recorded using standardized comparative photographs. Corneal staining, subjective symptoms and local comfort were measured using a four-step scale. All adverse events were recorded. Results Among 1,157 patients enrolled, 1,075 patients were treated with the preservative-free fixed combination as the only medication at the final visit. Medical treatment was initiated in 741 patients because of an insufficient IOP-lowering effect of the prior medication. In 343 patients, medication was changed because of tolerability issues. The preservative-free fixed combination lowered IOP significantly in the subgroup of naïve patients, all subgroups with prior monotherapy and patients with prior fixed combinations: naïve patients: −8.9 mmHg, alpha- 2-agonists: −6.4 mmHg, beta-blockers: −5.7 mmHg, carbonic anhydrase inhibitors: −5.2 mmHg, prostaglandins: −4.7 mmHg, fixed-combination prostaglandins/timolol: −2.4 mmHg. At the final visit, clinical signs and subjective symptoms were improved in patients with prior medical therapy. Local comfort was rated as “very good” or “good” by 89.1% of patients at the final visit. Only few adverse events occurred during the treatment period. Conclusion The preservative-free fixed combination of tafluprost 0.0015%/timolol 0.5% was effective, well tolerated and showed a good safety profile.

Abstract
PURPOSE Plasma concentrations of tafluprost acid and timolol were compared after single (Day 1) and repeated (Day 8) instillations of once-daily tafluprost 0.0015%-timolol 0.5% preservative-free (PF) fixed-dose combination (FDC), once-daily PF tafluprost 0.0015%, and twice-daily PF timolol 0.5%. PATIENTS AND METHODS Fifteen healthy volunteers were randomized to this double-masked, single-center, three-period cross-over study. A wash-out interval of at least 4 weeks separated each three 8-day dosing period. Blood samples were drawn on the first and last day of each dosing period, prior to the morning dose, as well as 5, 10, 15, 30, and 45 min, and 1, 1.5, 2, 4, 8, and 12 h post-dosing. Sample plasma concentrations of tafluprost acid and/or timolol were determined and maximum concentration (C max), area under the concentration-over-time curve from time zero to the last time point with a quantifiable measurement (AUC0-last), and time to maximum concentration were calculated. Intraocular pressure (IOP), adverse events, and ocular/systemic safety variables were also evaluated. RESULTS Plasma concentrations of tafluprost acid were low, with similar levels measured subsequent to either single or repeated dosing of PF FDC and PF tafluprost. On both sampling days, concentrations peaked at 10 min after the dose, and were cleared from the blood circulation by 30 min; average C max ranged from 17 to 24 pg/mL, and AUC0-last from 3 to 5 pg*h/mL. Plasma concentrations of timolol were comparable after the first dose of PF FDC or PF timolol. Concentrations peaked at 15 min post-dose and diminished in a similar manner after 2 h; average C max was 800 pg/mL and AUC0-last 3900 pg*h/mL. As expected, PF timolol produced a higher Day 8 pre-dose timolol concentration than PF FDC (235 vs. 37 pg/mL; p < 0.001, respectively). The Day 8 post-dose changes in timolol concentrations were relative to this pre-dose difference. All study treatments were well tolerated and safe. PF FDC seemed to provide the best IOP reduction. CONCLUSIONS PF FDC demonstrated good IOP-lowering efficacy and displayed similar pharmacokinetic characteristics to the monotherapy agents. Exposure to timolol was reduced via the halved dosing.

Abstract
Childhood glaucoma is a major therapeutic challenge for pediatric ophthalmologists and glaucoma specialists worldwide. Management depends on the etiology and age at presentation. A variety of drugs are available for the control of intraocular pressure in children; however, none of these drugs have been licensed by the regulatory agencies for use in children. Furthermore, evidence gained from randomized controlled trials in the pediatric population is sparse, and little is known regarding the use of newer anti-glaucoma preparations. This evidence-based review aims to discuss the available pharmacotherapeutic options for glaucoma in children. Topical adrenoceptor blockers, topical and systemic carbonic anhydrase inhibitors, prostaglandin (PG) analogs, adrenoceptor agonists, parasympathomimetics, and combined preparations are available for use in children, but usually as an off-label indication. Therefore, it is important to recognize that serious side effects have been reported, even with topical drops, and measures to reduce systemic absorption should be taken. Most drugs have been shown to have comparable ocular hypotensive effects, with the lowest occurrence of systemic side effects with PG analogs. Whereas a newly introduced prostaglandin analog, tafluprost, and some other preservative-free preparations have shown promising results in adult glaucoma patients, no pediatric reports are available as yet. Future studies may describe their role in treating pediatric glaucoma. This review also shares some suggested treatment pathways for primary congenital glaucoma (PCG), juvenile open angle glaucoma (JOAG), developmental glaucoma, aphakic/pseudophakic glaucoma, and uveitic glaucoma.

Abstract
AIM To draw a Meta-analysis over the comparison of the intraocular pressure (IOP)-lowering efficacy and safety between the commonly used fixed-combinations of prostaglandin analogs and 0.5% timolol with prostaglandin analogs (PGAs) monotherapy. METHODS After searching the published reports from MEDLINE, EMBASE, the Cochrane Library, all randomized controlled clinical trials (RCTs) comparing the fixed combination of PGAs/timolol therapy (FCs) and PGAs monotherapy with treatment duration at least 6mo were included. The efficacy outcomes were mean diurnal IOP, percentage of participants whose IOP were lower than 18 mm Hg, incidence of visual field change, while the safety outcomes included corneal side effects, hyperemia and eye irritation. The analysis was carried out in RevMan version 5.3 software. RESULTS After six-month medical intervention, the mean diurnal IOP of FCs was lower than PGAs (MD -1.14, 95% CI -1.82 to -0.46, P=0.001); the percentage of target IOP achieving between FCs and PGAs showed no significant difference (RR 1.18, 95% CI 0.97 to 1.43, P=0.10). No statistically significant differences of the incidence of hyperemia (RR 0.67, 95% CI 0.45 to 1.01, P=0.06) and eye irritation (RR 1.20, 95% CI 0.95 to 1.51, P=0.12) between the FCs and PGAs monotherapy were detected. Only one research involved in corneal events, result of this trial revealed no difference between two intervention groups regarding corneal effects (central endothelial cell density, MD -0.20, 95% CI -0.72 to 0.32, P=0.45; central corneal thickness, MD -0.01, 95% CI -0.02 to 0.00, P=0.23). The evaluation of visual field change was not performed due to the limited duration of the trials included in this Meta-analysis. CONCLUSION The long-term efficacy of the FCs overweighed the PGAs monotherapy in lowering IOP, but in the incidence of hyperemia and eye irritation syndromes, the differences are not statically significant. More RCTs with detailed and authentic data over the assessments of visual functions and morphology of optic nerve heads are hoped to be conducted.

Abstract
Primary (or chronic) open-angle glaucoma (POAG or COAG) may be asymptomatic but causes progressive optic nerve damage with significant loss of visual field. Treatments aim to lower intraocular pressure (IOP) by reducing the production of aqueous humour and/or increasing its drainage. Here we update our previous articles to reflect new drugs, preservative-free preparations and fixed-dose drug combinations for POAG.

Abstract
A new preservative-free fixed-dose combination of 0.0015% tafluprost, a prostaglandin F2α analog, and 0.5% timolol (TAF/TIM; Santen Oy, Tampere, Finland), a beta-adrenergic antagonist has recently been developed. The intraocular pressure (IOP) reduction with TAF/TIM in open-angle glaucoma and ocular hypertension is similar to that of other prostaglandin–timolol fixed-combination products. Patients with high IOP responded well to TAF/TIM with reductions of up to 40% (>13 mmHg) and beyond. Compared to previous controlled and double-masked clinical trials with DuoTrav® (Alcon, Fort Worth, USA) and Ganfort® (Allergan, Irvine, USA), TAF/TIM caused less superficial ocular side effects and less conjunctival hyperemia. Plausible explanations for the differences in side effects between the fixed-combination products are discussed.
