Trial Summary

Do I need to stop my current medications for the trial?

The trial information does not specify if you need to stop taking your current medications.

What data supports the effectiveness of the drug Bimatoprost for treating glaucoma?

Research shows that Bimatoprost effectively lowers eye pressure in people with glaucoma or high eye pressure. It has been found to work better than some other treatments, like timolol and latanoprost, in reducing eye pressure and maintaining it over time. ^{1 2 3 4 5}

Is unpreserved bimatoprost safe for humans?

Research on bimatoprost, including its use in eye drops and implants, shows it is generally safe for humans. Studies have evaluated its safety in different forms and concentrations, such as 0.01% and 0.03% solutions, and as a sustained-release implant, with no major safety concerns reported. ^{1 2 4 5 6}

What makes the drug Bimatoprost unique for treating glaucoma?

Bimatoprost is unique because it is a synthetic prostamide analog that effectively lowers intraocular pressure (IOP) by increasing fluid outflow in the eye, and it has been shown to be more effective than some other treatments like timolol. Additionally, it can be administered as a sustained-release implant, reducing the need for daily eye drops. ^{4 5 7 8 9}

What is the purpose of this trial?

This trial is testing a new treatment called T4032. It aims to see if T4032 is as effective as Lumigan® 0.01% for patients with glaucoma or high eye pressure. The study will compare how well each treatment reduces eye pressure.

Eligibility Criteria

This trial is for individuals with open-angle glaucoma or ocular hypertension in both eyes who have signed an informed consent.

Findings from Research

The bimatoprost implant (Durysta™) is a biodegradable drug delivery system that provides sustained release of bimatoprost to lower intraocular pressure (IOP) for 4 to 6 months, making it a convenient treatment option for patients with open angle glaucoma or ocular hypertension.

Approved in March 2020, the implant represents a significant advancement in glaucoma treatment, allowing for prolonged IOP control without the need for daily eye drops, and its clinical development is still ongoing.

Bimatoprost Implant: First Approval. Shirley, M.[2020]

In a two-month study involving 1283 patients, bimatoprost significantly lowered intraocular pressure (IOP) by an average of 3.4 mm Hg, with the percentage of patients achieving target pressures of ≤18 mm Hg doubling from 33% to 66%.

Bimatoprost was well-tolerated, with conjunctival hyperemia being the most common side effect (3.7%), indicating it is a safe and effective alternative to latanoprost for managing glaucoma and ocular hypertension.

Ocular hypotensive efficacy of bimatoprost when used as a replacement for latanoprost in the treatment of glaucoma and ocular hypertension. Bournias, TE., Lee, D., Gross, R., et al.[2018]

Bimatoprost effectively lowers intraocular pressure (IOP) in patients with open-angle glaucoma and ocular hypertension, showing approximately 1-2 mmHg greater IOP reduction compared to latanoprost and superior efficacy over timolol in clinical trials.

Long-term use of bimatoprost maintains its effectiveness without significant safety concerns, with common side effects being mild conjunctival hyperaemia and eyelash growth, making it a valuable treatment option for glaucoma.

An update on bimatoprost in glaucoma therapy. Cantor, LB.[2019]

In a study of 6,767 patients with glaucoma or ocular hypertension, bimatoprost 0.03% monotherapy significantly lowered intraocular pressure (IOP) by an average of 7.5 mmHg (30%) after 2 months, demonstrating its efficacy in untreated patients.

Bimatoprost was well tolerated, with 41.5% of patients achieving target IOPs of ≤15 mmHg and 75.8% reaching ≤18 mmHg, although the most common side effect reported was conjunctival hyperemia (7.9%).

Efficacy of bimatoprost 0.03 percent in untreated glaucoma and ocular hypertension patients: results from a large community-based clinical trial. Quinones, R., Severin, T., Mundorf, T.[2015]

In a study of 122 eyes from 84 patients, bimatoprost sustained-release (SR) significantly reduced intraocular pressure (IOP) from 18.5 mmHg to 16.0 mmHg and decreased the number of required glaucoma medications from 2.1 to 1.2, indicating its efficacy in managing glaucoma.

Among 41 eyes from 31 patients with prior glaucoma surgeries, bimatoprost SR also reduced medication burden, showing a decrease from 1.9 to 1.0 medications, suggesting it is effective even for patients who have undergone previous surgical interventions.

Effect of bimatoprost sustained-release intracameral implant on intraocular pressure and medication burden in patients with prior glaucoma surgery. Bowers, ME., Wong, MK., Ventimiglia, J., et al.[2023]

Bimatoprost effectively lowers intraocular pressure (IOP) by 7-8 mmHg over 24 hours when used as a 0.03% topical preparation once daily, making it more effective than timolol and comparable to other prostaglandin analogs.

While bimatoprost is generally safe, with mild side effects like conjunctival hyperemia and periorbital pigmentation, it is also cost-effective for treating open-angle glaucoma, especially when used in combination with other medications.

Bimatoprost - a review. Patil, AJ., Vajaranant, TS., Edward, DP.[2015]

Bimatoprost is a highly effective medication for lowering intraocular pressure in patients with glaucoma and ocular hypertension, providing consistent control throughout the day.

As a synthetic molecule similar to prostamide F(2), bimatoprost mimics prostamide activity, which contributes to its strong ocular hypotensive effects and indicates its unique pharmacological properties.
