E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Diabetic Macular Edema (DME) |
|
E.1.1.1 | Medical condition in easily understood language |
DME is a common eye complication of diabetes.It causes blood vessels in the retina at the back of the eye to leak, causing swelling.Swelling of the macula leads to vision loss & possible blindness. |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The principal study objective is to compare the treatment efficacy of ranibizumab versus bevacizumab in eyes with DME. |
|
E.2.2 | Secondary objectives of the trial |
Safety outcomes - This will include the number and severity of adverse events. The number of eyes withdrawn from the investigational product due to vision loss or adverse events and the number of eyes deemed to have worsening disease will also contribute to the assessment of safety. Blood samples will be used for exploratory analyses including immunity and genetic studies that will investigate ophthalmic diseases, immunomodulation and the differing responses of participants to novel and existing treatments. |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
(1) Participant is 18 years of age or older. (2) Participant has a diagnosis of diabetic 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 ADA and/or WHO criteria. (3) Participant must understand and sign the protocol’s informed consent document. (4) Female participants of childbearing potential (see Appendix 1 for definition) must not be pregnant or breast-feeding and must have a negative pregnancy test at screening and must agree to pregnancy testing throughout the study. (5) Female participants of childbearing potential (see Appendix 1) and male participants able to father children must have (or have a partner who has) had a hysterectomy or vasectomy, be completely abstinent from intercourse or must agree to practice two acceptable methods of contraception throughout the course of the study and for four weeks after their last injection. Acceptable methods of contraception include: Hormonal contraception (i.e., birth control pills, injected hormones, dermal patch or vaginal ring); Intrauterine device; Barrier methods (i.e., diaphragm, condom) with spermicide; or Tubal ligation. (6) Participant has at least one eye that meets all of the following criteria: eye has a BCVA ETDRS score between 20/32 and 20/400; eye has definite retinal thickening or cystic changes due to DME based on clinical exam involving the center of the macula that is not refractory to further therapy as based on the investigator’s clinical judgment; eye has retinal thickness in the central subfield on baseline OCT measurement ≥ 330 microns, as measured by Cirrus™ OCT; eye has clear ocular media and adequate pupillary dilation sufficient for adequate fundus photographs; eye does not have macular edema considered to be due to a cause other than diabetes (an eye is not eligible if: the macular edema is considered to be related to cataract extraction, or clinical examination and/or OCT suggest that vitreoretinal interface disease (e.g., a taut posterior hyaloid or epiretinal membrane) is the primary cause of the macular edema); eye does not have an ocular condition 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 hard exudates, non-retinal condition); eye does not have an ocular condition present (other than DR) 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.); eye does not have a history of panretinal scatter photocoagulation (PRP) within three months prior to enrollment; eye does not have a history of prior pars plana vitrectomy prior to enrollment; eye does not have a history of major ocular surgery (including cataract extraction, scleral buckle, any intraocular surgery, etc.) within three months prior to enrollment; eye does not have a history of Yttrium-Aluminum-Garnet (YAG) capsulotomy performed within two months prior to enrollment; eye has not had laser photocoagulation treatment, or received intravitreal or periocular steroids within three months prior to enrollment; eye does not have a history of intravitreal anti-VEGF agents within eight weeks prior to enrollment; eye has not had greater than four intravitreal anti-VEGF injections within one year prior to enrollment; and eye does not have high-risk proliferative diabetic retinopathy requiring laser photocoagulation treatment. |
|
E.4 | Principal exclusion criteria |
(1) Participant is in another investigational study and actively receiving investigational product for DME. (2) Participant has a known hypersensitivity to sodium fluorescein dye. (3) Participant has a condition that, in the opinion of the investigator, would preclude participation in the study (e.g., unstable medical status including blood pressure and glycemic control). (4) Participant has a history of chronic renal failure requiring dialysis or kidney transplant. (5)Participant has a history of liver failure. (6) Participant has a known hypersensitivity to bevacizumab, ranibizumab or any of their components. (7) Participant has a blood pressure of > 180/110 (systolic above 180 OR diastolic above 110). If blood pressure is brought below 180/110 by anti-hypertensive treatment, a patient can become eligible. (8) Participant has a history of treatment with oral steroids ( ≥ 10 mg of prednisone daily or equivalent) within three months prior to enrollment. Non-ocular depot and inhaled steroid treatments will not exclude a participant. (9) Participant has a history of treatment with systemic anti-VEGF agents within four weeks prior to enrollment. |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary outcome measure is the mean change in ETDRS BCVA. Changes in BCVA from baseline to four weeks following the end of each of the three periods (i.e., Weeks 12, 24 and 36) will be used for the primary analysis. Change in BCVA through Years 1, 2 and 3 will be assessed as a confirmatory analysis. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Changes in BCVA from baseline to four weeks following the end of each of the three periods (i.e., Weeks 12, 24 and 36) and at Years 1, 2 and 3 will be used for the primary analysis. |
|
E.5.2 | Secondary end point(s) |
Secondary outcomes will include: the mean changes in central macular thickness and central retinal volume by treatment group as measured by OCT; the slope of the changes in BCVA, central macular thickness and retinal volume; the proportion of eyes with visual improvement ≥ 10 letters; the proportion of eyes with visual improvement ≥ 15 letters; the proportion of eyes with ≥ 0.1 log unit loss or gain in logOCT; the proportion of eyes with ≥ 0.05 log unit loss or gain in logOCT; changes in fluid leakage in the macula as demonstrated by fluorescein angiography; and changes in macular structural improvement (i.e., resolution of cystic changes) as measured by OCT; the proportion of eyes meeting criteria for significant worsening, treatment success, or treatment failure; the frequency of re-injection among eyes in the treatment-as-needed phase of the study; the proportion of eyes receiving focal/grid laser photocoagulation or other adjuvant treatment during the course of the study. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
These will be assessed between the baseline and Week 12 visits, Weeks 12 and 24 visits and Weeks 24 and 36 visits and at Years 1, 2 and 3. |
