    Data support adding suprachoroidal injection to anti-VEGF for RVO

    Additive approach augments results of intravitreal anti-VEGF with encouraging safety profile



    Combination therapy with suprachoroidal triamcinolone acetonide (Zuprata, Clearside Biomedical) injection plus an intravitreal anti-vascular endothelial growth factor (VEGF) agent is a promising approach for treating eyes with macular edema and vision loss associated with retinal vein occlusion (RVO), said David M. Brown, MD.

    The suprachoroidal injection is administered using a proprietary microinjector syringe featuring a proprietary short (900 μm), 30-gauge needle.

    Evaluation in animal models showed the technique resulted in compartmentalization of the corticosteroid with high levels achieved in target tissues (choroid and retina) and limited penetration to the anterior segment.

    In the 3-month TANZANITE trial, patients receiving a single suprachoroidal injection of triamcinolone acetonide plus intravitreal
    aflibercept 2 mg (Eylea, Regeneron) had a significantly reduced need for further anti-VEGF injections compared with the control group assigned to an initial aflibercept injection plus a sham suprachoroidal procedure, explained Dr. Brown, TANZANITE investigator and clinical professor of ophthalmology, Baylor College of Medicine, Houston.
