Study Details

Study Description

Brief Summary

The purpose of the study is to find out if treatment with an intravitreal injection of triamcinolone or an intravitreal injection of ranibizumab can prevent loss of vision caused by panretinal photocoagulation treatment. At the present time, it is not known whether intravitreal steroid or anti-vascular endothelial growth factor (anti-VEGF) injections are beneficial in preventing vision loss after panretinal photocoagulation (PRP) treatment. It is possible that one or both of the types of injections will prevent vision loss after PRP treatment. However, it is not known whether the benefits of the injections will outweigh the risks. It is possible that because of side effects, the injections may not be as good as laser alone in treating the diabetic retinopathy.

Phase 3

Detailed Description

Proliferative diabetic retinopathy (PDR) is manifested in retinal neovascularization at the disc (NVD) or elsewhere (NVE). Vitreous hemorrhage or tractional detachment from PDR is a leading cause of severe visual loss and new onset blindness. Without intervention, 60 percent of individuals with diabetic retinopathy will eventually develop PDR, resulting in significant visual loss in nearly fifty percent.

Proliferative diabetic retinopathy is currently treated with panretinal photocoagulation (PRP) which destroys areas of the retina but preserves central vision. PRP is most effectively seen in a regression of new vessels, stabilization of the neovascularization, and reduced risk of visual loss. However, the treatment is associated with unavoidable side effects including macular edema with transient or permanent central vision loss, diminished vision loss, and night vision loss. The treatment applies laser burns to the peripheral retinal tissue, destroying outer photoreceptors and retinal pigment epithelium of the retina, and is thought to exert its effect by increasing oxygen delivery to the inner retina and decreasing viable hypoxic cells which are producing growth factors such as VEGF. Studies have implicated vascular endothelial growth factor (VEGF) as the substance leading to neovascularization and/or increased vascular permeability. Thus, it is reasonable to expect that inhibition of VEGF could reduce both PDR and transient vision loss from macular edema. There are several anti-VEGF drugs. Ranibizumab is the drug to be evaluated in this trial. In one trial of ranibizumab on DME, ten patients with chronic DME received a series of 0.5 mg intraocular injections. The treatments were well tolerated with no ocular or systemic adverse events. Since intraocular injections of ranibizumab significantly reduced foveal thickness and improved visual acuity in all ten patients, there is strong rationale to consider this drug as adjunctive therapy to PRP in a attempt to reduce the acute, transient edema that may occur with PRP.

Similarly, corticosteroids, a class of substances with anti-inflammatory properties, have demonstrated to inhibit the expression of VEGF. Triamcinolone acetonide is often used as a periocular injection for the treatment of cystoid macular edema (CME) secondary to uveitis. Clinically, triamcinolone acetonide is used in the treatment of proliferative vitreoretinopathy and choroidal neovascularization. Studies on patients with proliferative diabetic retinopathy randomly assigned to receive 4 mg triamcinolone 10 to 15 days prior to PRP treatment showed a reduction in central macular thickening, and fluorescein leakage was greater in the injection group than in the control group at 9 and 12 months follow up. Mean visual acuity improved by one line in the injection group and worsened by two lines in the control group.

In summary, there is strong rationale that using either intravitreal ranibizumab or intravitreal triamcinolone acetonide as an adjunct to PRP could reduce the magnitude of vision loss.

This study is being conducted to determine whether intravitreal injection of an anti-VEGF drug or an intravitreal injection of a corticosteroid can reduce the occurrence of macular edema and visual acuity impairment following PRP. Subjects will be randomly assigned with equal probability to one of the following three injection groups:

  • Intravitreal injection of 0.5 mg ranibizumab (Lucentis™) at baseline and 4 weeks

  • Intravitreal injection of 4 mg triamcinolone acetonide at baseline and sham injection at 4 weeks

  • Sham injection at baseline and 4 weeks

The initial injection (or sham) is given on the day of randomization. Focal (macular) photocoagulation is given 7 to 10 days following the injection. Panretinal (scatter) photocoagulation can be initiated either on the same day as the focal photocoagulation (immediately following the focal photocoagulation) or on a subsequent day but must be initiated within 14 days of the baseline injection. Required follow-up visits occur at 4, 14, 34 and 56 weeks.

    Outcome Measures

    Primary Outcome Measures

    1. Change in Electronic Early Treatment Diabetic Retinopathy Study Visual Acuity Letter Score From Baseline to 14 Weeks [baseline to 14 weeks]

      Visual Acuity was measured with the Electronic Early Treatment Study (E-ETDRS) visual acuity test. Unit of measure is based on the E-ETDRS letter score scale, 0-97, where 0 = worst and 97 = best.

    Secondary Outcome Measures

    1. Additional Treatments for Diabetic Macular Edema [14 weeks to 56-weeks]

      Each combination of treatment is only counted once per treatment eye. Participants could have 2 study eyes, with random assignments to different treatments.

    2. Change in Optical Coherence Tomography Central Subfield Thickness [Baseline to 14 weeks]

    3. Total Optical Coherence Tomography Retinal Volume [Baseline to 14-weeks]

      Missing/ungradable as follows: Sham = 49, Ranibizumab = 37, Triamcinolone = 39. Visits occured between 70 days and 153 days from randomization adjusted for baseline optical coherence tomography (OCT) retinal volume, OCT retinal thickness and visual acuity, number of planned panretinal photocoagulation sittings, and correlation between 2 study eyes. Confidence intervals are adjusted for multiple comparisons.

    4. Change in Visual Acuity From Baseline [baseline to 56-weeks]

      Visual Acuity was measured with the Electronic Early Treatment Study (E-ETDRS) visual acuity test. Unit of measure is based on the E-ETDRS letter score scale, 0-97, where 0 = worst and 97 = best.

    5. Eyes With Anti-vascular Endothelial Growth Factor Treatment for Diabetic Macular Edema [14 weeks to 56-weeks]

    6. Number of Eyes With Additional Number of Treatments for Diabetic Macular Edema [14 weeks to 56-weeks]

      Treatments include any type or combination of treatment for diabetic macular edema. Eyes were only counted once, when receiving a combination of treatments.

    7. Change in Optical Coherence Tomography Retinal Volume [Baseline to 14 weeks]

      Missing or un-gradable data as follows for the sham plus focal/grid/panretinal photocoagulation laser, triamcinolone plus focal/grid panretinal photocoagulation laser, and Ranibizumab groups were 49, 37, and 39, respectively

    Study Results

    Participant Flow

    Recruitment Details Data from 1 clinical site where a majority of eyes were judged not to meet the Optical Coherence Tomography eligibility criterion of central subfield >=250 microns when graded manually at a central reading center (14 eyes of 10 subjects) are excluded from all analysis except for safety data.
    Pre-assignment Detail Participants with 2 study eyes enrolled each eye in a different arm. Each treatment arm includes no more than 1 study eye for a given participant, and thus the numbers of eyes is equal to the number of participants in each arm.

    Outcome Measures

    1. Primary Outcome
    Title Change in Electronic Early Treatment Diabetic Retinopathy Study Visual Acuity Letter Score From Baseline to 14 Weeks
    Description Visual Acuity was measured with the Electronic Early Treatment Study (E-ETDRS) visual acuity test. Unit of measure is based on the E-ETDRS letter score scale, 0-97, where 0 = worst and 97 = best.
    Time Frame baseline to 14 weeks

    Outcome Measure Data

    Analysis Population Description
    Participants with 2 study eyes enrolled each eye in a different arm. Each arm includes no more than 1 study eye for a given participant, and thus the numbers of eyes is equal to the number of participants in each arm. Analysis followed intention to treat principle; eyes without 14-week data, the Last Observation Carried Forward method was used.
    Arm/Group Title Sham Injection 0.5mg Ranibizumab 4-mg Triamcinolone Acetonided
    Arm/Group Description Sham injection at baseline and 4 weeks Intravitreal injections of 0.5mg Ranibizumab at baseline and at 4 weeks 4-mg Triamcinolone Acetonide at baseline and sham injection at 4 weeks
