NCT01572350

Brief Summary

This clinical trial is designed to investigate differences in terms of efficacy (mean change in best corrected visual acuity obtained after 12 months of treatment) and safety, of 3 therapeutic estrategies for non-tractional macular edema in diabetic patients: a) laser alone; b) laser plus tiramcinolon; and c) laser plus bevacizumab.

Conditions

Outcome Measures

Primary Outcomes (1)

  • Best-Corrected Visual Acuity (BCVA)

    To evaluate the effect on best-corrected visual acuity (BCVA) of intravitreal triamcinolone (Triesence ®) or bevacizumab (Avastin ®) in combination with grid laser therapy compared to grid laser therapy alone after 12 months of treatment, in diabetic patients with not tractional diffuse macular edema (NTDDEM)

    12 months

Secondary Outcomes (4)

  • To assess the safety of intravitreal Triesence (r)

    Baseline, 3m, 6m and 12 months

  • To measure average change in mean central macular thickness in each group.

    Baseline and 3, 6 and 12 months after the treatment was initiated.

  • To assess the safety of intravitreal Avastin (r)

    Baseline, 3m, 6m and 12 months

  • To assess the safety of intravitreal grid photocoagulation

    Baseline, 3m, 6m and 12 months

Study Arms (3)

Grid laser

ACTIVE COMPARATOR

It's a reference standard as the treatment which is currently accepted for NTDDME

Other: Grid laser

Triamcinolone 4 mg

EXPERIMENTAL
Drug: Triamcinolone Acetonide

Bevacizumab

EXPERIMENTAL
Drug: Bevacizumab

Interventions

Grid laser therapy acts as the standard to refer to as it is the treatment which is currently accepted by EMDDNT.

Grid laser

Triamcinolone 4 mg followed by modified grid laser therapy after 3-4 weeks

Also known as: Triesence
Triamcinolone 4 mg

Bevacizumab (1.25 mg initially, weeks 6 and 12) followed by modified grid laser therapy after3-4 weeks

Also known as: Avastin
Bevacizumab

Eligibility Criteria

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

You may qualify if:

  • Age ≥18 years from both sexes. Women of childbearing age should use adequate contraception methods and submit a negative pregnancy test.
  • Diagnosis of diabetes mellitus type 1 or type 2 (documented by ADA or WHO guidelines) and serum HbA1c \<11% at the time of randomization (determinations done in the last two months).
  • Patient able to give informed consent.
  • Eye with clear media, pupil dilation and patient able to cooperate to perform retinography, OCT and fluorescein angiography.
  • Patients with clinically significant diabetic macular edema; the patient must have at least one:
  • ) retinal thickening within 500 μ from the center or 5.2) hard exudates within 500 μ from the center if associated with adjacent retinal thickening or 5.3) the size of retinal thickening at least 1 area disc, part of which is less than 1 DD of the center.
  • Patients with diffuse diabetic macular edema.
  • Patients with not tractional diabetic macular edema.

You may not qualify if:

  • Women of childbearing age not using adequate contraceptive methods.
  • Pregnancy and lactation. Pregnancy test was performed before starting treatment.
  • Chronic renal failure requiring dialysis or kidney transplantation.
  • Allergy to any of the drugs included in the study.
  • Systemic use of steroids in the last 4 months.
  • Patient intends to change his place of residence within 3 years after recruitment, whenever you go to an area not covered by the study.
  • Blood pressure\>180/110. If blood pressure is brought below 180/110 by anti-hypertensive treatment, patient can become eligible.
  • HbA1c\> 11% in the current analysis or done in the last 2 months.
  • An ocular condition is present such that, in the opinion of the investigator, visual acuity would not improve from resolution of macular edema (e.g., foveal atrophy, pigmentary changes, dense subfoveal hare exudates, nonretinal condition).
  • An ocular condition is present (other than diabetes) that, in the opinion of the investigator, might affect macular edema or alter visual acuity during the course of the study (e.g., vein occlusion, uveitis or other ocular inflammatory disease, neovascular glaucoma, Irvine-Gass Syndrome, etc.)
  • Substantial cataract that, in the opinion of the investigator, is likely to be decreasing visual acuity by 3 lines or more
  • History of prior treatment with intravitreal corticosteroids or intravitreal antiangiogenic.
  • History of peribulbar steroid injection within 6 months prior to randomization.
  • History of focal, grid or panretinal photocoagulation within 4 months prior to randomization.
  • Need of panretinal photocoagulation in the first 4 months of treatment.
  • +10 more criteria
