Glaucoma is a group of chronic eye diseases that are characterized by a progressive optic nerve damage and consequent visual loss. In most cases, it is associated with elevated intraocular pressure. If glaucoma left untreated, complete blindness can occur. Prostaglandin analog- timolol FCs are common glaucoma therapy because these drugs have been shown to effectively lower intraocular pressure (IOP). It is also known that chronic use of preservatives in the drops leads to ocular surface disease (OSD) which can lead to low tolerability of prescribed drops and gaps in the dosing regimen.
The purpose of this study is to investigate whether drug preservative elimination results in reduction of OSD symptoms and signs as well as improvement of latanoprost-timolol FC local tolerability in the treatment of glaucoma and ocular hypertension.
In this trial, on each visit (V1, V2 and V3) following tests will be used: Snellen visual acuity, IOP measurement by Goldman applanation tonometry, OSD signs assessment on the slit lamp (corneal and conjunctival fluorescein surface staining, conjunctival hyperemia and tear film stability assessment using Tear Break- up Time test - TBUT). Visual Analog Scale (VAS) will be used for a subjective assessment of drug tolerability. The association of quality of life and dry eye symptoms in participants will be measured by the Ocular Surface Disease Index (OSDI) questionnaire.

Efficacy and Safety of Latanoprost/Timolol Fixed Combination Dosed Twice Daily Compared to Once Daily in Patients With Primary Open Angle Glaucoma

Intraocular pressure (IOP) is the most important modifiable risk factor to prevent and delay progression of glaucoma. IOP reduction has been proven to delay the onset and progression of glaucoma, and uncontrolled IOP is constantly associated with progression of visual field loss.
Medical therapy is the first line in IOP reduction for Primary Open Angle Glaucoma (POAG). It is a known fact that glaucoma patients often require addition of a second antiglaucoma medications when disease progresses or tachyphylaxis occurs. It was reported that more than 50% of patients require 2 or more medications to achieve optimum IOP control.
Nevertheless, compliance and adherence are often impaired with multiple-drug therapy. Combining two ocular hypotensive agents in one bottle may help patients adhere to therapeutic regimen by reducing the number of medications used and the total number of doses administered.

Efficacy and Safety Assessment of Fixed Combination Unpreserved Latanoprost Eye Drops and Timolol 0.5% (T2347) Versus Xalacom® in Ocular Hypertensive or Glaucomatous Patients.

The objective of the study is to assess the efficacy and safety of T2347 (Latanoprost 0.005% + Timolol 0.5% unpreserved eye drops) versus Xalacom® in ocular hypertensive or glaucomatous patients initially treated, stabilised by Xalacom® or generics (fixed combination Latanoprost 0.005% + Timolol 0.5% preserved eye drops).

In Vitro Toxicity Evaluation of New Generic Latanost® and Latacom® as an Ophthalmic Formulation

Article

Author: Yee, Kar Ming ; Alwi, Nor Amalina Ahmad ; Ng, Jessica Sze Chia ; Tan, Yi Xin ; Tan, Ka-Liong ; Leong, Chuei Wuei ; Rashid, Ahmad Hazri Abdul

AIM AND OBJECTIVE:

To evaluate the safety of two new generic ophthalmic formulations, Latanost^® (latanoprost) and Latacom^® (latanoprost and timolol) by utilizing the three-dimensional reconstructed human cornea-like epithelium (RhCE) tissue constructs as an in vitro model in the assessment of ocular irritation.

MATERIALS AND METHODS:

In vitro irritation test was conducted on Latanost^® (LTN) and Latacom^® (LTC) and their corresponding innovators, Xalatan^® (XLT) and Xalacom^® (XLC), respectively, by using RhCE. According to the OECD guidelines No. 492 on the testing of chemicals, the ophthalmic formulations were assessed via topical exposure of the formulations on in vitro RhCE tissue. Cell viability was measured by MTT assay.

RESULTS:

The mean cell viability percentage of LTN and XLT was 70.5 and 75.7%, respectively, whereas, for LTC and XLC, the percentage viability was 95.3 and 85.7%, respectively. The two new generic formulations (LTN and LTC) did not reduce the cell viability of the RhCE tissue to ≤60%. Thus, both can be considered as nonirritant.

CONCLUSION:

Both newly developed generics are nonocular irritants.

CLINICAL SIGNIFICANCE:

This study informs the safety assessment of new generic antiglaucoma ophthalmic solutions applicable for long-term glaucoma treatment. The formulations aim to keep eye irritation to a minimum level.

Xalacom: possibilities and advantages of the drug in the treatment of patients with glaucoma

Review

Author: Volkova, A V ; Alekseev, I B ; Alekseeva, L I

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.

Noninferiority of Preservative-free Versus BAK-preserved Latanoprost-timolol Fixed Combination Eye Drops in Patients With Open-angle Glaucoma or Ocular Hypertension

Q3 · MEDICINE

Article

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.
