RANDOMIZED, OPEN LABEL, PARALLEL-GROUP, TWO-ARM, MULTICENTER STUDY WITH CLINICAL ENDPOINT COMPARING PRESERVATIVE FREE BIMATOPROST OPHTHALMIC SOLUTION 0.1 MG/ML AND LUMIGAN® (BIMATOPROST OPHTHALMIC SOLUTION) 0.1 MG/ML IN PATIENTS WITH CHRONIC OPEN-ANGLE GLAUCOMA OR OCULAR HYPERTENSION IN ONE OR BOTH EYES.
This study is looking at two types of eye drops for people with high pressure in their eyes (called ocular hypertension) or a condition called chronic open-angle glaucoma. Both eye drops contain the same active ingredient, bimatoprost, which helps lower eye pressure. One type is already widely used (Lumigan), and the other is a new version that doesn't contain preservatives. Preservatives can sometimes irritate the eyes. The main goal is to see if the new preservative-free drops lower eye pressure just as effectively as the existing drops. We'll also check if the new drops are more comfortable to use and if there are any new side effects. This research could lead to a gentler treatment option for eye conditions.
At a glance
What is this study about?
You might be wondering what this study is all about. Well, it's looking at different eye drops for common eye conditions: high pressure in the eye, known as ocular hypertension, and chronic open-angle glaucoma. Both these conditions can damage your optic nerve if left untreated, potentially affecting your vision.
Currently, many people use eye drops containing a medicine called bimatoprost to help lower this eye pressure. One common brand is Lumigan. This study wants to compare the usual Lumigan drops with a newer version that doesn't have preservatives. Sometimes, preservatives in eye drops can cause irritation or discomfort for patients, especially if used for a long time. So, the main aim is to see if these new preservative-free drops work just as well to lower eye pressure.
Beyond checking their effectiveness, we also want to understand if the preservative-free drops are more comfortable to use and if they have fewer side effects. Finding a treatment that is both effective and comfortable is really important for people who need to use eye drops every day. This research could potentially offer a better, gentler option for managing these eye conditions in the future.
Key takeaways
- This study compares two bimatoprost eye drops for high eye pressure or glaucoma.
- One drop is the standard treatment (Lumigan), the other is a new preservative-free version.
- The main goal is to see if the preservative-free drops work as well and are more comfortable.
- Participation involves using eye drops daily and attending regular check-up appointments for about 6 weeks.
- This research aims to find potentially gentler treatment options for common eye conditions.
Who may be eligible?
To join this study, you need to be an adult, 18 years or older, and have either high pressure in your eyes (ocular hypertension) or chronic open-angle glaucoma. Both men and women can take part.
Doctors will carefully check your eyes and overall health to make sure this study is right for you. They'll look at your eye pressure and other measurements to ensure you meet all the specific requirements set for the study.
It's important that you don't have any other serious eye conditions that might affect the results, or any other health problems that could make the treatment unsafe for you. Your doctor will discuss all these details with you.
Could this study suit you?
Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.
- Are you 18 years old or older?
- Have you been diagnosed with high eye pressure (ocular hypertension)?
- Have you been diagnosed with chronic open-angle glaucoma?
- Are you able to attend clinic appointments for about six weeks?
- Are you able to use eye drops daily as instructed?
What does participation involve?
If you decide to take part, you'll be given either the new preservative-free bimatoprost eye drops or the standard Lumigan eye drops to use. You won't get to choose which one you receive, as this is decided randomly, much like flipping a coin, to ensure the comparison is fair. You will need to use these drops daily in one or both of your eyes, as instructed by the study doctor.
Over a period of about six weeks (42 days), you'll have several visits to the clinic. These visits will involve checks on your eye pressure, which is a main focus of the study. Doctors will also ask you about how your eyes feel and if you've noticed any irritation or discomfort. They will also keep an eye out for any side effects.
These regular check-ups and careful monitoring are crucial for understanding how well each type of eye drop works and how comfortable they are for patients. The total duration of active treatment and follow-up in the study will be around six weeks.

Common questions
What is glaucoma?
Glaucoma is an eye condition where the optic nerve, which connects your eye to your brain, becomes damaged. This is often due to high pressure inside your eye. Untreated, it can lead to vision loss.
What are 'preservative-free' eye drops?
Preservative-free eye drops don't contain added chemicals that prevent bacteria from growing. For some people, these preservatives can cause irritation or discomfort, especially with long-term use.
Will I know which eye drops I'm getting?
No, you won't know if you're getting the standard or the preservative-free drops. This 'blinding' helps ensure the study results are fair and unbiased.
How long will the study last for me?
Your participation in the study, including using the drops and having check-ups, will last for about six weeks (42 days).
Can I stop taking part if I change my mind?
Yes, absolutely. You can decide to leave the study at any time, for any reason, and your regular medical care will not be affected.
