Brief Summary:
To see if Lucentis 0.5mg combined with Targeted Pan Retinal photocoagulation will decrease the total number of intravitreal injections in a year for ischemic central retinal vein occlusion, hemi-retinal vein occlusions and branch retinal vein occlusions compared to standard of care

Condition or disease Intervention/treatment Phase
Central Retinal, Hemi Retinal & Brach Retinal Vein Occlusions Drug: 0.5mg Ranibizumab Procedure: Targeted Pan Retinal Photocoagulation Phase 4

Detailed Description:

The WAVE trial is a phase IV, open label, 12-month trial of intravitreal ranibizumab 0.5 mg in patients (n=30) with ischemic CRVO, HRVO and BRVO who have been previously treated with ranibizumab or any other anti-VEGF intravitreal injection therapy, who are incomplete responders to 2 or more consecutive intravitreal anti-VEGF injections in the past 4 months. Randomization is 1:4, 1=control, ranibizumab only, 4=treatment arm. In total, 6 subjects will be randomized to control and 24 randomized to treatment arm.

Cohort 1- 24 Subjects previously treated Patients will receive 6 doses of ranibizumab 0.5 mg, followed by PRN intravitreal injection of ranibizumab 0.5 mg based on pre-defined retreatment criteria for up to 11 total injections.

Wide field angiography guided peripheral targeted-retinal photocoagulation (TRP), will be divided into 2 sessions if needed, one at the 2 weeks post injection visit and another later at M4/V7, if repeat wide field angiogram indicates areas not sufficiently treated in the first TRP session

Cohort 2- 6 Subjects, previously treated patients will receive 6 doses of ranibizumab 0.5 mg, followed by PRN intravitreal injection of ranibizumab 0.5 mg based on pre-defined retreatment criteria for up to 11 total injections.

Drug Information available for: Ranibizumab

Arm Intervention/treatment
Experimental: Targeted Pan Retinal laser combined with 0.5mg ranibizumab
Cohort 1 (n=24), previously treated with at least 2 consecutive or more intravitreal injections of any anti-VEGF agent with persistent or recurrent macular edema will receive 6 loading doses of 0.5 mg ranibizumab followed by PRN treatment with ranibizumab 0.5 mg; after receiving the first loading dose of ranibizumab, the subject will have peripheral targeted-retinal photocoagulation (TRP) based on 200° wide field angiography with possibility of a second session of TRP at M4/M7, if non-perfusion persists based on angiogram.The 200°wide field angiography will indicate areas of peripheral ischemia which will be selectively treated, preserving areas of more perfused retina.
Drug: 0.5mg Ranibizumab

Primary Outcome Measures :
  1. Total Number of Intravitreal Injections Over a 12 Month Period [ Time Frame: 12 months ]
    Assess the number of intravitreal injections over 12 months.

  2. Visual Acuity [ Time Frame: 12 month period ]
    Evaluate the mean change from baseline in ETDRS best-corrected visual acuity at 12 months. The ETDRS protocol is a widely accepted international standard for macular laser photocoagulation treatment. A higher score represents better functioning.


Secondary Outcome Measures :
  1. Retinal Ischemia [ Time Frame: 12 month period ]
    Quantify change in area of perfused and ischemic retina.

  2. Foveal Avascular Zone [ Time Frame: 12 months ]
    Assess change in foveal avascular zone area and largest diameter, measured during the early phase of the angiogram

  3. Adverse Events [ Time Frame: 12 months ]
    Incidence and severity of adverse events (ocular and non-ocular).

  4. Neovascularization of the Iris, Optic Nerve and Elsewhere [ Time Frame: 12 months ]
    Percent of patients that develop neovascularization of the iris, optic nerve and/or elsewhere.

  5. Central Foveal Outcome [ Time Frame: 12 months ]
    Mean change in Central Foveal Volume on High Resolution OCT.

  6. Aqueous VEGF Levels [ Time Frame: 12 Months ]
    VEGF, other cytokines and ranibizumab levels in aqueous and serum samples at randomization and at the exit or early termination visit.

  7. Visual Field [ Time Frame: 6 and 12 Months ]
    Goldman Visual Field changes at 6 and 12 months from baseline. Goldmann perimetry is a method used to map a patient's field of vision (central and peripheral). Changes will be assessed by manual digital quantification of GVF plots.

  • History of other disease, metabolic dysfunction, physical examination finding, or other findings giving reasonable suspicion of a disease or condition that contraindicates the use an investigational drug, might affect interpretation of the results of the study, or render the subject at high risk from treatment complications
  • History of allergy to fluorescein, not amenable to treatment
  • Inability to obtain fundus photographs or fluorescein angiograms of sufficient quality to be analyzed by the principal investigator (PI) and/or the sub-investigator.
  • History of allergy to humanized antibodies or any component of the ranibizumab formulation
