MERIT: Macular Edema Treatment Study

Clinical Trial Title: 
Macular edema ranibizumab v. intravitreal anti-inflammatory therapy trial (MERIT).
Clinical Trial Protocol ID: 
16111505
Clinical Trial Investigator Name: 
Pauline Merrill, MD
Clinical Trial Protocol Description: 

The Macular Edema Ranibizumab v. Intravitreal anti-inflammatory Therapy (MERIT) Trial will compare the relative efficacy and safety of intravitreal methotrexate, intravitreal ranibizumab, and the intravitreal dexamethasone implant for the treatment of uveitic macular edema persisting or reoccurring after an intravitreal corticosteroid injection. MERIT is a parallel design (1:1:1), randomized comparative trial with an anniversary close-out at the 6 month clinic visit. The primary outcome is percent change in central subfield thickness from the baseline OCT measurement to the 12 week visit.

Clinical Trial Eligibility Criteria: 

In order to participate you must meet the following criteria:

  • Are 18 years of age or older.
  • Have inactive or minimally active non-infectious anterior, intermediate, posterior or panuveitis, as defined by SUN132 criteria as ≤ 0.5+ anterior chamber cells, ≤ 0.5+ vitreous haze grade and no active retinal/choroidal lesions for a minimum of 4 weeks.
  • Have macular edema (ME) defined as the presence of macular thickness greater than the normal range for the OCT machine being used (see cut points below), regardless of the presence of cysts, following an intravitreal corticosteroid injection (≥ 4 weeks following intravitreal triamcinolone injection or ≥ 12 weeks following intravitreal dexamethasone implant injection). Greater than 300 μm for Zeiss Cirrus Greater than 320 μm for Heidelberg Spectralis Greater than 300 μm for Topcon 3DOCT.
  • Have a baseline fluorescein angiogram that, as assessed by the study ophthalmologist, is gradable for degree of leakage in the central subfield.
  • Have best corrected visual acuity (BCVA) 5/200 or better.
