Rhee T, Kim J, Ha A. Preservative-Free Fixed Combination of Tafluprost 0.0015% and Timolol 0.5% for Treatment-Naive Patients with Open-Angle Glaucoma. 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.

[PMID: 38794131 PMCID: PMC11124470 DOI: 10.3390/ph17050561] [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: 03/25/2024] [Revised: 04/17/2024] [Accepted: 04/25/2024] [Indexed: 05/26/2024] Open
Abstract
BACKGROUND Bimatoprost has emerged as a significant medication in the field of medicine over the past several decades, with diverse applications in ophthalmology, dermatology, and beyond. Originally developed as an ocular hypotensive agent, it has proven highly effective in treating glaucoma and ocular hypertension. Its ability to reduce intraocular pressure has established it as a first-line treatment option, improving management and preventing vision loss. In dermatology, bimatoprost has shown promising results in the promotion of hair growth, particularly in the treatment of alopecia and hypotrichosis. Its mechanism of action, stimulating the hair cycle and prolonging the growth phase, has led to the development of bimatoprost-containing solutions for enhancing eyelash growth. AIM The aim of our review is to provide a brief description, overview, and studies in the current literature regarding the versatile clinical use of bimatoprost in recent years. This can help clinicians determine the most suitable individualized therapy to meet the needs of each patient. METHODS Our methods involve a comprehensive review of the latest advancements reported in the literature in bimatoprost formulations, which range from traditional eye drops to sustained-release implants. These innovations offer extended drug delivery, enhance patient compliance, and minimize side effects. RESULTS The vast literature published on PubMed has confirmed the clinical usefulness of bimatoprost in lowering intraocular pressure and in managing patients with glaucoma. Numerous studies have shown promising results in dermatology and esthetics in promoting hair growth, particularly in treating alopecia and hypotrichosis. Its mechanism of action involves stimulating the hair cycle and prolonging the growth phase, leading to the development of solutions that enhance eyelash growth. The global use of bimatoprost has expanded significantly, with applications growing beyond its initial indications. Ongoing research is exploring its potential in glaucoma surgery, neuroprotection, and cosmetic procedures. CONCLUSIONS Bimatoprost has shown immense potential for addressing a wide range of therapeutic needs through various formulations and advancements. Promising future perspectives include the exploration of novel delivery systems such as contact lenses and microneedles to further enhance drug efficacy and patient comfort. Ongoing research and future perspectives continue to shape its role in medicine, promising further advancements and improved patient outcomes.

MERCURY-3: a randomized comparison of netarsudil/latanoprost and bimatoprost/timolol in open-angle glaucoma and ocular hypertension. Graefes Arch Clin Exp Ophthalmol 2024; 262:179-190. [PMID: 37615697 PMCID: PMC10806046 DOI: 10.1007/s00417-023-06192-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2023] [Revised: 06/22/2023] [Accepted: 07/23/2023] [Indexed: 08/25/2023] Open
Abstract
PURPOSE : To compare the efficacy and safety of the fixed-dose combination (FDC) of netarsudil 0.02%/latanoprost 0.005% ophthalmic solution (NET/LAT; Roclanda®) with bimatoprost 0.03%/timolol maleate 0.5% (BIM/TIM; Ganfort®) ophthalmic solution in the treatment of open-angle glaucoma (OAG) and ocular hypertension (OHT). METHODS MERCURY-3 was a 6-month prospective, double-masked, randomized, multicenter, active-controlled, parallel-group, non-inferiority study. Patients (≥ 18 years) with a diagnosis of OAG or OHT in both eyes that was insufficiently controlled with topical medication (IOP ≥ 17 mmHg in ≥ 1 eye and < 28 mmHg in both eyes) were included. Following washout, patients were randomized to once-daily NET/LAT or BIM/TIM for up to 6 months; efficacy was assessed at Week 2, Week 4, and Month 3; safety was evaluated for 6 months. Comparison of NET/LAT relative to BIM/TIM for mean IOP at 08:00, 10:00, and 16:00 h was assessed at Week 2, Week 6, and Month 3. Non-inferiority of NET/LAT to BIM/TIM was defined as a difference of ≤ 1.5 mmHg at all nine time points through Month 3 and ≤ 1.0 mmHg at five or more of nine time points through Month 3. RESULTS Overall, 430 patients were randomized (NET/LAT, n = 218; BIM/TIM, n = 212), and all received at least one dose of study medication. Efficacy analyses were performed at Month 3 on 388 patients (NET/LAT, n = 184; BIM/TIM, n = 204). NET/LAT demonstrated non-inferiority to BIM/TIM, with a between-treatment difference in IOP of ≤ 1.5 mmHg achieved at all time points and ≤ 1.0 mmHg at the majority of time points (six of nine) through Month 3. Mean diurnal IOP during the study ranged from 15.4 to 15.6 mmHg and 15.2 to 15.6 mmHg in the NET/LAT and BIM/TIM groups respectively, with no between-group statistically significant difference. No significant differences were observed in key secondary endpoints. No serious, treatment-related adverse events (AEs) were observed, and AEs were typically mild/moderate in severity. The most common treatment-related AEs were conjunctival hyperemia (NET/LAT, 30.7%; BIM/TIM, 9.0%) and cornea verticillata (NET/LAT, 11.0%; BIM/TIM, 0%). CONCLUSIONS Once-daily NET/LAT was non-inferior to BIM/TIM in IOP reduction in OAG and OHT, with AEs consistent with previous findings. NET/LAT offers a compelling alternative FDC treatment option for OAG and OHT.

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
The strategy of glaucoma therapy is aimed at preserving visual functions and ensuring an acceptable quality of life for patients. To achieve this strategic goal, clinicians in their practice use drugs that affect the main factor in the progression of the disease - intraocular pressure (IOP), aiming to reduce it to an individual target level. It is not always possible to achieve optimal IOP values with monotherapy. Many patients require a combination of drugs from different pharmacological groups. Xalacom is a fixed drug with good tolerability and t hypotensive effect. This review focuses on the benefits of this drug for the treatment of glaucoma.

Abstract
Purpose: In this study, we evaluated the efficacy of topical hypotensive treatment and/or systemic corticosteroids therapy in patients with elevated intraocular pressure and Graves’ orbitopathy (GO). Methods: We included 172 eyes in 86 individuals with duration of GO ≥ 3 months, intraocular pressure in either eye ≥ 25.0 mmHg, and GO ranked ≥ 3 at least in one eye in modified CAS form. The study subjects were divided into three treatment subgroups: subgroup I was administered latanoprost once a day; subgroup II was administered a combined preparation of brimonidine and timolol BID; subgroup III was the control group, not receiving any topical hypotensive treatment. All the study participants received systemic treatment, intravenous corticosteroid therapy at the same dose, according to the European Group of Graves’ Orbitopathy (EUGOGO) guideline. Results: On the final visit, the mean IOP value was significantly lower in all treatment subgroups compared to the initial values. In both subgroups receiving topical treatment, the IOP reduction was higher than in the control group receiving systemic corticosteroids only. However, the latanoprost eye drops decreased intraocular pressure more effectively than drops containing brimonidine and timolol. Conclusion: Topical ocular hypotensive treatment is effective in reducing intraocular pressure in GO and decreases intraocular pressure more effectively than systemic corticosteroid therapy alone.

Abstract
PRéCIS:: Noninferiority of efficacy was demonstrated for a preservative-free latanoprost-timolol fixed combination compared with a BAK-containing formulation at 84 days after treatment in patients with open-angle glaucoma or ocular hypertension. PURPOSE The purpose of this study was to compare the effect on intraocular pressure and safety of preservative-free latanoprost-timolol fixed combination (T2347) to benzalkonium chloride-preserved latanoprost-timolol fixed combination in patients with open-angle glaucoma or ocular hypertension. METHODS Phase III, randomized, parallel-group, investigator-masked study in 10 countries. A total of 242 patients aged 18 years or older with open-angle glaucoma or ocular hypertension in both eyes controlled with a preserved latanoprost-timolol fixed combination (15.7±2.4 mm Hg overall before inclusion) were randomized at day 0 with no washout period to receive the preservative-free alternative T2347 (N=127) or remain on the preserved comparator (N=115) for 84 days. Intraocular pressure changes from day 0 were measured at 9:00 am (±1 hour) on day 42 and day 84, and noninferiority of T2347 to the preserved comparator was analyzed statistically at day 84. Safety parameters were also reported. RESULTS The mean change in intraocular pressure from baseline to day 84 was -0.49±1.80 mm Hg for preservative-free T2347 and -0.49±2.25 mm Hg for the preserved comparator. These results met the noninferiority limits. Similar results were observed at day 42. There was no difference between groups in the incidence of adverse events or ocular signs. The total ocular symptoms score was better for T2347 than BPLT upon instillation at day 84 (45.9%/44.3%/9.8% of patients with improvement/no change/worsening vs. 33.6%/47.3%/19.1%; P=0.021), reflecting improvements in individual symptoms such as irritation/burning/stinging (P<0.001), and itching (P<0.01) on day 84. CONCLUSIONS Preservative-free latanoprost-timolol fixed combination T2347 showed noninferior efficacy compared with the preserved comparator and was well tolerated.

Abstract
GOALS To assess the efficacy and safety of preservative-free timolol 0.1% gel in patients with primary open-angle glaucoma (POAG) and ocular hypertension (OHT). METHODS In this multicenter, open-label, non-controlled clinical trial in Algeria, treatment-naïve patients with intraocular pressure (IOP)>20mmHg and<31mmHg (treatment-naïve patients, group 1) and patients with IOP controlled by current ocular monotherapy but presenting with local intolerance in at least one eye (intolerant patients; group 2) were eligible. Timolol gel was administered once daily in the morning for 84 days. The primary efficacy criteria were reduction in IOP (group 1) and maintenance of baseline IOP (group 2). RESULTS Overall, 93 patients were included (53 in group 1, 40 in group 2). All patients in group 2 had been previously treated with preserved eye drops. In group 1, patients showed a significant reduction in IOP with mean changes in the worse eye of -10.3±3.0mmHg at D28 and -10.8±2.5mmHg at D84 (P<0.0001). In group 2, the maintenance of efficacy on IOP at D84 was satisfactory in 91.7% of patients (worse eye). Preservative-free timolol gel was well tolerated in both groups. In group 2, the overall symptom score was significantly reduced from 8.6±5.1 to 0.9±1.6 at D28 and 0.7±1.2 at D84 (P<0.0001), and the overall ocular sign score from 3.7±2.1 to 0.8±1.0 at D28 and 0.6±0.8 at D84 (P<0.0001). CONCLUSIONS This preservative-free timolol 0.1% gel was effective in decreasing IOP in treatment-naïve patients and in controlling IOP and reducing ocular signs and symptoms in patients intolerant to their previous preserved medications.

Abstract
Purpose To evaluate the ocular-surface safety of a 0.001% benzalkonium chloride-containing tafluprost/timolol fixed combination (TTFC) in patients with primary open-angle glaucoma (POAG) or ocular hypertension who have inadequate intraocular pressure (IOP) control with latanoprost monotherapy. Methods This study is a multicenter, prospective, single-arm, open-label clinical study. Patients with POAG or ocular hypertension who have inadequate IOP control with latanoprost monotherapy were considered eligible. After providing informed consent, patients continued latanoprost monotherapy for 12 weeks, followed by a switch to TTFC. We evaluated the extent of ocular-surface damage using superficial punctate keratopathy (SPK) score, tear breakup time (TBUT), hyperemia score, IOP, systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate at 0, 4, and 12 weeks after switching. Results A total of 68 patients were enrolled, of whom, 64 patients were included in the final analysis. No significant changes in SPK score, TBUT, or hyperemia score were observed at 4 and 12 weeks compared with week 0. IOP decreased significantly at 4 (13.9±2.5 mmHg) and 12 (14.1±2.5 mmHg) weeks, relative to week 0 (15.3±2.7 mmHg). No significant changes in either SBP or DBP were observed during the study, although patients’ mean heart rate decreased significantly after switching to TTFC. Adverse drug reactions to TTFC occurred in seven patients including two incidences of asthma and one of arrhythmia, and no events were serious. Conclusion The ocular-surface safety of TTFC is not significantly different to that of latanoprost. Furthermore, switching from latanoprost to TTFC in patients with insufficient IOP control has additive IOP-lowering effects. TTFC is an effective approach for patients receiving latanoprost monotherapy who require more intensive IOP reduction.

Abstract
We evaluated the cytotoxic effects of four prostaglandin analogs (PGAs) used to treat glaucoma. First we established primary cultures of conjunctival stromal cells from healthy donors. Then cell cultures were incubated with different concentrations (0, 0.1, 1, 5, 25, 50 and 100%) of commercial formulations of bimatoprost, tafluprost, travoprost and latanoprost for increasing periods (5 and 30 min, 1 h, 6 h and 24 h) and cell survival was assessed with three different methods: WST-1, MTT and calcein/AM-ethidium homodimer-1 assays. Our results showed that all PGAs were associated with a certain level of cell damage, which correlated significantly with the concentration of PGA used, and to a lesser extent with culture time. Tafluprost tended to be less toxic than bimatoprost, travoprost and latanoprost after all culture periods. The results for WST-1, MTT and calcein/AM-ethidium homodimer-1 correlated closely. When the average lethal dose 50 was calculated, we found that the most cytotoxic drug was latanoprost, whereas tafluprost was the most sparing of the ocular surface in vitro. These results indicate the need to design novel PGAs with high effectiveness but free from the cytotoxic effects that we found, or at least to obtain drugs that are functional at low dosages. The fact that the commercial formulation of tafluprost used in this work was preservative-free may support the current tendency to eliminate preservatives from eye drops for clinical use.
