NCT01331005

Brief Summary

This study is being conducted to assess the effects of topical nonsteroidal anti-inflammatories (NSAIDs) on macular retinal volume compared with placebo in eyes with non-central diabetic macular edema (DME). A secondary objective of this study is to assess the effects of topical NSAIDs on central subfield thickness and to compare the progression of non-central DME to central DME as determined by optical coherence tomography (OCT) and stereoscopic fundus photographs. Furthermore, this phase II study is being conducted (1) to determine whether the conduct of a phase III trial has merit based on an anatomic outcome, (2) to estimate recruitment potential of a phase III investigation, and (3) to provide information on outcome measures needed to design a phase III trial. The study is not designed to establish the efficacy of NSAIDs in the treatment of non- central DME.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age \>18 years
  • Type 1 or type 2 diabetes
  • Only one study eye per subject may be enrolled. The study eye must meet the following:
  • Best corrected E-ETDRS visual acuity letter score ≥ 74 (i.e., 20/32 or better) within 8 days of enrollment.
  • On clinical exam, definite retinal thickening due to DME within 3000 μm of the center of the macula but not involving the central subfield.
  • Thickened non-central macular subfields on DRCR.net approved spectral domain OCT macular map.
  • Central subfield thickness within threshold definition for normal central subfield thickness on DRCR.net approved spectral domain OCT machine.
  • No focal/grid laser within the last 6 months or other treatment for DME within the last 4 months.
  • No anticipated need to treat DME during the course of the study, unless the eye meets the criteria for treatment (Central subfield retinal thickness increases to 310 μm or more in spectral domain OCT machine from baseline).
  • Diagnosis of diabetes mellitus (type 1 or type 2). Any one of the following will be considered to be sufficient evidence that diabetes is present:
  • Current regular use of insulin for the treatment of diabetes.
  • Current regular use of oral anti-hyperglycemia agents for the treatment of diabetes.
  • Documented diabetes by American Diabetes Association and/or the World Health Organization criteria.
  • At least one eye meets the study eye criteria.
  • Able and willing to provide informed consent.
  • +12 more criteria

You may not qualify if:

  • A condition that, in the opinion of the investigator, would preclude participation in the study (e.g., unstable medical status including blood pressure, cardiovascular disease, and glycemic control).
  • Subjects in poor glycemic control who, within the last 4 months, initiated intensive insulin treatment (a pump or multiple daily injections) or plan to do so in the next 4 months should not be enrolled.
  • Use of systemic corticosteroids or anti-VEGF therapy.
  • Current use of prescription systemic NSAIDs.
  • History of auto-immune diseases such as rheumatoid arthritis.
  • Participation in an investigational trial that involved treatment with any drug within 30 days of randomization that has not received regulatory approval at the time of study entry.
  • Note: study participants cannot receive another investigational drug while participating in the study.
  • Known allergy to any component of the study drug.
  • Blood pressure \> 180/110 mmHg (systolic above 180 or diastolic above 110 mmHg)
  • If blood pressure is brought below 180/110 by anti-hypertensive treatment, study participant can become eligible.
  • Participant is expecting to move out of the area of the clinical center to an area not covered by another clinical center during the 12 months of the study.
  • For women of child-bearing potential: pregnant or lactating or intending to become pregnant within the next 12 months.
  • Women who are potential study participants should be questioned about the potential for pregnancy. Investigator judgment is used to determine when a pregnancy test is needed.
  • History of focal/grid laser within the last 6 months or other treatment for DME within the last 4 months
  • Note: Throughout the study, the distribution of subjects with prior treatment for DME will be evaluated, and eligibility criteria may be tailored to add balance between subjects with prior treatment and subjects without prior treatment for DME.
  • +14 more criteria
