Topical Cyclosporine vs. Placebo for Epiphora Associated With Docetaxel

The Study Drugs:

Restasis® is also known as cyclosporine ophthalmic emulsion 0.05% (cyclosporine eye drops). It is designed to decrease eye inflammation.

FML Forte® is also known as fluorometholone 0.25% ophthalmic suspension (fluorometholone eye drops). It is designed to decrease eye inflammation. Fluorometholone eye drops are commonly used to help to control epiphora.

In this study, an additional type of eye drops will be used for comparison with cyclosporine eye drops. This second type of eye drops is called Refresh Endura™ (lubricant eye drops), which is designed to relieve dry eyes. Unlike cyclosporine and fluorometholone, it does not have active ingredients designed to treat epiphora.

Study Groups:

If you are found to be eligible to take part in this study, you will be assigned to 1 of 2 groups. The way of assigning participants to groups is mostly random, as in the flip of a coin. However, your epiphora score (how often you dabbed your tears, as recorded in a diary) will also affect what group you are assigned to.

Group 1 will receive cyclosporine eye drops and fluorometholone eye drops. Group 2 will receive lubricant eye drops and fluorometholone eye drops.

Neither you nor the study staff will know whether you are receiving cyclosporine eye drops or lubricant eye drops. However, if needed for your safety, the study staff will be able to find out which one you are receiving.

Study Drug Administration Your first dose of the study drugs will be given in the clinic on Day 1. After that, you will give yourself the rest of the doses at home. The study staff will teach you how to use the eye drops, and you will be given written instructions. Study data will be collected on both eyes, and you will apply the drops to both eyes.

If you wear contact lenses, be sure to take your contact lenses out before using the eye drops. Fifteen (15) minutes after your dose of the eye drops, you may put your contact lenses back in.

If you are in Group 1, you will apply 1 drop of cyclosporine eye drops to each eye, 2 times a day, for 84 days (12 weeks) in a row. You should wait about 12 hours between doses.

If you are in Group 2, you will apply 1 drop of lubricant eye drops to each eye, 2 times a day, for 84 days in a row. You should wait about 12 hours between doses.

All study participants must wait at least 10 minutes after you have applied your other eye drops (cyclosporine or the lubricant) before you can apply the fluorometholone eye drops.

All study participants will receive fluorometholone eye drops. During Week 1, you will apply 1 drop to each eye, 4 times a day. During Week 2, you will apply 1 drop to each eye, 3 times a day. During Week 3, you will apply 1 drop to each eye, 2 times a day. During Week 4, you will apply 1 drop to each eye, once a day.

Study Visits:

On Visit 1 (Day -1 or -2), your eye doctor and/or study staff will ask you to sign the written informed consent. Screening tests will be done, which include urine pregnancy test for all women who are able to become pregnant, and other eye exams, such as Best Corrected Visual Acuity, Biomicroscopy, Intraocular Pressure (IOP), Epiphora Assessments, Schirmer's Test, and Probing and Irrigation Test. Your eye doctor and/or assistant will explain these different eye exams, or any questions you may have, at the day of your visit. You will also be asked about the different medications that you are currently taking. You will be given participant diaries for you to record or keep track of your medication use and how many times you dab your tears. You will then be given the schedule of your next visit.

On Visit 2 (Day 0 or baseline), the study staff will record how well you tolerate the study drugs and any side effects that may occur after the doses. You will also complete 2 questionnaires. The first questionnaire asks about the quality of your life and the second questionnaire asks about any problems with your vision that you may be experiencing. In total, they should take about 10-15 minutes to complete.

You will be given additional patient diaries. In the first diary, you will record any missed doses of the study drugs. In the second diary, you will record how many times you dab tears from your eyes and/or face, starting 24 hours before each clinic visit.

You should bring the completed patient diaries and the used containers of the study drugs with you to every study visit.

At Weeks 2, 4, and 8, the following procedures will be performed:

• You will have a routine eye exam to check the status of the epiphora. The same eye tests will be performed as at screening. However, the routine procedure called "probing and irrigation" (a test of the tear ducts, involving water) may not need to be repeated. The probing and irrigation procedure will only be performed if the epiphora seems to have gotten worse. In that case, the probing and irrigation procedure will help the doctor decide whether to recommend that you consider additional treatments.
• You will be asked about any side effects you may have experienced, any other drugs or treatments you may be receiving, and any other changes to your current drugs or treatments.
• You will repeat the quality-of-life questionnaire. You will also complete a second questionnaire about your overall eye comfort and a third questionnaire about the eye tearing symptoms. In total, these questionnaires should take about 20 minutes to complete.

Length of Study Participation:

You may stay on study treatment for up to 12 weeks. If intolerable side effects occur, or the epiphora gets worse and the study doctor thinks you should consider surgery to treat it, you will be taken off study treatment early.

End-of-Study Visit:

After your last dose of the study drugs (at Week 12, or earlier if you go off study treatment early), you will return for an end-of-study visit. At this visit, the following procedures will be performed:

• You will have the same procedures performed as at Weeks 2, 4, and 8.
• You will complete the quality-of-life questionnaire, the questionnaire that asks about any problems with your vision, and the questionnaire that asks if your eye tearing symptoms have improved or gotten worse compared to the days before you started the study. In total, these questionnaires should take about 20 minutes to complete.
• Women who are able to have children will have a urine pregnancy test.

THIS IS AN INVESTIGATIONAL STUDY. Cyclosporine eye drops, fluorometholone eye drops, and Refresh Endura™ lubricant eye drops are commercially available for other eye conditions. They are not FDA approved for use in treating epiphora. At this time and for this purpose, they are considered experimental. This includes fluorometholone eye drops, which are commonly used to treat epiphora but are not FDA approved for this use.

Up to 40 patients will take part in this study. All will be enrolled at M. D. Anderson.
