Overview
11 DESCRIPTION Ranibizumab is a recombinant humanized IgG1 kappa isotype monoclonal antibody fragment for intraocular use. Ranibizumab binds to and inhibits the biologic activity of human vascular endothelial growth factor-A (VEGF-A). Ranibizumab, which lacks an Fc region, has a molecular weight of approximately 48 kilodaltons and is produced by an E.
Mechanism of Action
12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Ranibizumab binds to the receptor binding site of multiple biologically active forms of VEGF-A, including VEGF 110 . VEGF-A has been shown to cause neovascularization and leakage in models of ocular angiogenesis and vascular occlusion and is thought to contribute to pathophysiology of neovascular AMD. The binding of ranibizumab to VEGF-A prevents the interaction of VEGF-A with its receptors (VEGFR1 and VEGFR2) on the surface of endothelial cells, reducing endothelial cell proliferation, vascular leakage, and new blood vessel formation. 12.3 Pharmacokinetics The SUSVIMO implant provides a continuous release of ranibizumab where the release of ranibizumab into the vitreous decreases over time as the concentration in the implant decreases.
Indications
- 1 INDICATIONS AND USAGE SUSVIMO (ranibizumab injection) is a vascular endothelial growth factor (VEGF) inhibitor indicated for the treatment of patients with: Neovascular (wet) Age-related Macular Degeneration (AMD) who have previously responded to at least two intravitreal injections of a VEGF inhibitor ( 1.1 ). Diabetic Macular Edema (DME) who have previously responded to at least two intravitreal injections of a VEGF inhibitor ( 1.2 ). Diabetic Retinopathy (DR) who have previously responded to at least two intravitreal injections of a VEGF inhibitor ( 1.3 ). 1.

Black Box Warning
WARNING: ENDOPHTHALMITIS The SUSVIMO implant has been associated with an up to 3-fold higher rate of endophthalmitis than monthly intravitreal injections of ranibizumab. Many of these events were associated with conjunctival retractions or erosions. Appropriate conjunctiva management and early detection with surgical repair of conjunctival retractions or erosions may reduce the risk of endophthalmitis. [see Contraindications (4.1) , Warnings and Precautions (5.1) ] . WARNING: ENDOPHTHALMITIS See full prescribing information for complete boxed warning.
Contraindications
