TREX-DME: A Safety and Efficacy Trial of a Treat and Extend Protocol Using Ranibizumab With and Without Laser Photocoagulation for Diabetic Macular Edema
Study Details
Study Description
Brief Summary
The purpose of this research study is to determine if a "Treat and Extend" regimen (increasing the time between visits when the disease is stable and not getting worse) of Ranibizumab 0.3 mg injections inside the eye is safe and effective at treating patients with swelling of the retina from diabetes.

Phase 1/Phase 2 |
Detailed Description
This research study will compare the visual outcomes between a group of patients who are treated with monthly injections of Ranibizumab 0.3 mg and two groups of patients who are treated with the "Treat and Extend" regimen. One of the "Treat and Extend" groups will also receive laser therapy to determine if this has any additional beneficial effects.

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Active Comparator: Monthly Monthly Cohort (30 eyes) - Study eyes will receive intravitreal injections of 0.3 mg ranibizumab every 4 weeks for 24 months. |
Drug: Ranibizumab 0.3 mg intravitreal injection
Other Names:
|
Active Comparator: TREX (60 eyes) - Monthly intravitreal injections of 0.3 mg ranibizumab for four visits. At the fourth visit (Week 12), if the central foveal thickness is ≤ 325 μm then the eye will receive 0.3 mg ranibizumab and begin the extension phase of the study. For all subsequent visits in the extension phase, appropriate changes to the treatment interval with 0.3 mg ranibizumab (i.e. extend, maintain, reduce) will be made based on pre-specified SD (Spectral Domain)-OCT criteria. Treatment is rendered at every visit. The time between visits is individualized based on each subject's response to treatment. If the central foveal thickness is > 325 μm at week 12, then the patient will continue to receive monthly intravitreal injections of 0.3 mg ranibizumab until the central foveal thickness is ≤ 325 μm. Once the central foveal thickness is ≤ 325 μm, then the study eye will begin the extension phase of the study. |

Active Comparator: GILA (60 eyes) - Monthly intravitreal injections of 0.3 mg ranibizumab for four visits combined with guided laser photocoagulation to all microaneurysms in the area of DME at visit 2 (Week 4) and then again every 3 months, if leakage is present on fluorescein angiography. If the central foveal thickness is ≤ 325 μm at visit 4 (Week 12), eyes will receive 0.3 mg ranibizumab and the extension phase will begin. For all subsequent visits in the extension phase, appropriate changes to the treatment interval with 0.3 mg ranibizumab (i.e. extend, maintain, reduce) will be made based on pre-specified SD-Optical coherence tomography criteria. If the central foveal thickness is > 325 μm at week 12, then the patient will continue to receive monthly intravitreal injections of 0.3 mg ranibizumab and possible guided laser every 3 months until the central foveal thickness is ≤ 325 μm. Once the central foveal thickness is ≤ 325 μm, then the study eye will begin the extension phase of the study. |

Outcome Measures
Primary Outcome Measures

Arm/Group Description | Monthly Cohort (30 eyes) - Study eyes will receive intravitreal injections of 0.3 mg ranibizumab every 4 weeks for 24 months. Ranibizumab 0.3 mg intravitreal injection | (60 eyes) - Monthly intravitreal injections of 0.3 mg ranibizumab for four visits. At the fourth visit (Week 12), if the central foveal thickness is ≤ 325 μm then the eye will receive 0.3 mg ranibizumab and begin the extension phase of the study. For all subsequent visits in the extension phase, appropriate changes to the treatment interval with 0.3 mg ranibizumab (i.e. extend, maintain, reduce) will be made based on pre-specified SD (Spectral Domain)-OCT criteria. Treatment is rendered at every visit. The time between visits is individualized based on each subject's response to treatment. If the central foveal thickness is > 325 μm at week 12, then the patient will continue to receive monthly intravitreal injections of 0.3 mg ranibizumab until the central foveal thickness is ≤ 325 μm. Once the central foveal thickness is ≤ 325 μm, then the study eye will begin the extension phase of the study. Ranibizumab 0.3 mg intravitreal injection | (60 eyes) - Monthly intravitreal injections of 0.3 mg ranibizumab for four visits combined with guided laser photocoagulation to all microaneurysms in the area of DME at visit 2 (Week 4) and then again every 3 months, if leakage is present on fluorescein angiography. If the central foveal thickness is ≤ 325 μm at visit 4 (Week 12), eyes will receive 0.3 mg ranibizumab and the extension phase will begin. For all subsequent visits in the extension phase, appropriate changes to the treatment interval with 0.3 mg ranibizumab (i.e. extend, maintain, reduce) will be made based on pre-specified SD-Optical coherence tomography criteria. If the central foveal thickness is > 325 μm at week 12, then the patient will continue to receive monthly intravitreal injections of 0.3 mg ranibizumab and possible guided laser every 3 months until the central foveal thickness is ≤ 325 μm. Once the central foveal thickness is ≤ 325 μm, then the study eye will begin the extension phase of the study. |

For all subsequent visits in the extension phase, appropriate changes to the treatment interval with 0.3 mg ranibizumab (i.e. extend, maintain, reduce) will be made based on pre-specified SD (Spectral Domain)-OCT criteria. Treatment is rendered at every visit. The time between visits is individualized based on each subject's response to treatment. If the central foveal thickness is > 325 μm at week 12, then the patient will continue to receive monthly intravitreal injections of 0.3 mg ranibizumab until the central foveal thickness is ≤ 325 μm. Once the central foveal thickness is ≤ 325 μm, then the study eye will begin the extension phase of the study. Ranibizumab 0.3 mg intravitreal injection | (60 eyes) - Monthly intravitreal injections of 0.3 mg ranibizumab for four visits combined with guided laser photocoagulation to all microaneurysms in the area of DME at visit 2 (Week 4) and then again every 3 months, if leakage is present on fluorescein angiography. If the central foveal thickness is ≤ 325 μm at visit 4 (Week 12), eyes will receive 0.3 mg ranibizumab and the extension phase will begin. For all subsequent visits in the extension phase, appropriate changes to the treatment interval with 0.3 mg ranibizumab (i.e. extend, maintain, reduce) will be made based on pre-specified SD-Optical coherence tomography criteria. If the central foveal thickness is > 325 μm at week 12, then the patient will continue to receive monthly intravitreal injections of 0.3 mg ranibizumab and possible guided laser every 3 months until the central foveal thickness is ≤ 325 μm. Once the central foveal thickness is ≤ 325 μm, then the study eye will begin the extension phase of the study. |
