Trial summary

Macular edema is a condition in which there is swelling in the macula, the part of the retina that gives you your best vision. This swelling can cause your vision to decline. When diagnosed early and treated, you vision usually can be preserved. Read more about this study

108 patients with uveitic ME will be enrolled at Aravind Eye Hospital in Madurai, India based on the following eligibility criteria:

About this study

Macular edema is a condition in which there is swelling in the macula, the part of the retina that gives you your best vision. This swelling can cause your vision to decline. When diagnosed early and treated, you vision usually can be preserved. However, if the swelling goes untreated for a long time, it can cause permanent vision loss.

We think that the three eye drop regimens in this study, difluprednate, difluprednate plus nepafenac, and prednisolone acetate plus nepafenac, might be effective in treating uveitic macular edema. Patients who enter this study are randomized to one of the three regimens and followed for 24 weeks.

Read the detailed description

Trial: Randomized 3 arm (1:1:1) parallel design comparative effectiveness trial

Stratification: Systemic corticosteroid/immunosuppressive therapy vs. none

Treatments: 1) difluprednate 0.05% 2) combination therapy of prednisolone acetate 1% with nepafenac 0.1% 3) combination therapy of difluprednate 0.05% with nepafenac 0.1%

Masking: Unmasked treatment administration; masked outcome assessment (evaluation of OCT and visual acuity)

Follow-up: 2, 4, 6, 8, and 24 weeks

Treatment protocol:

Patients will be randomized at enrollment to either:

  • difluprednate 0.05% 4 drops per day
  • prednisolone acetate 1% 4 drops per day and nepafenac 0.1% 3 drops per day
  • difluprednate 0.05% 4 drops per day and nepafenac 0.1% 3 drops per day

If macular edema has not resolved at Week 4, continue study treatment at the same dose until Week 6.

If macular edema has resolved at Week 4, reduce study treatment as follows:

  • difluprednate 0.05% 1 drop per day until Week 6, then stop
  • prednisolone acetate 1% 1 drop per day and nepafenac 0.1% 3 drops per day until Week 6, then stop
  • difluprednate 0.05% 1 drop per day and nepafenac 0.1% 3 drops per day until Week 6, then stop

If macular edema does not resolve at Week 4 but has resolved at Week 6, reduce study treatment at Week 6 as follows:

  • difluprednate 0.05% 1 drop per day until Week 8, then stop
  • prednisolone acetate 1% 1 drop per day and nepafenac 0.1% 3 drops per day until Week 8, then stop
  • difluprednate 0.05% 1 drop per day and nepafenac 0.1% 3 drops per day until Week 8, then stop If macular edema resolves at Week 4 but reoccurs at Week 6, treat per best medical judgement.

After Week 8, there are no restrictions on the treatments patients may receive, and medications can be tapered further, discontinued, or changed at the discretion of the treating physician and patient preference. If a patient with previously resolved macular edema has a recurrence, the physician may treat according to best medical judgement.

What is being measured

The primary outcome is the main question the study is designed to answer.

    proportion of patients with resolution of macular edema

    Measured: 4 weeks

  2. Improvement

    proportion of patients with improvement in macular edema defined as 20% or greater reduction in central subfield thickness by OCT or resolution of edema

    Measured: 4 weeks

  3. recurrence

    proportion of patients with recurrence of macular edema defined as greater than 20% increase in central subfield thickness to a value >320 microns by OCT or presence of cysts in an eye that previously had resolution of macular edema

    Measured: 4 weeks

  4. Intraocular pressure (IOP) increase

    number of patients with intraocular pressure increase at least 10mmHg over baseline

    Measured: 4 weeks

  5. High IOP

    Number of patients experiencing high intraocular pressure (> 24 mmHg)

    Measured: 4 weeks

  6. Visual acuity

    best-corrected visual acuity (ETDRS protocol)

    Measured: 4 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Difluprednate, Nepafenac and Prednisolone acetate in people with Uveitis and Macular Edema, run by University of California, San Francisco at 3 sites in India.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 13 Jan 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in India. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: Difficulty enrolling). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Central subfield thickness (time frame: 4 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Jan 2021.
