Update on Zimura Clinical Trials

As of the close of business on January 4, 2019, the Company enrolled a total of 57 patients for its OPH2005 randomized, double-masked, sham controlled, multi-center Phase 2b clinical trial evaluating the safety and efficacy of Zimura®(avacincaptad pegol)monotherapy for the treatment of autosomal recessive Stargardt disease (the “STGD1 Trial”). The Company plans to complete enrollment for the STGD1 Trial in the first quarter of 2019 and expects to enroll a total of 60 to 65 patients. The Company expects that initial, top-line data from this clinical trial will be available in the second half of 2020.

The Company has decided to discontinue its OPH2006 randomized, dose-ranging, open-label Phase 2a clinical trial of Zimura in combination with the anti-vascular endothelial growth factor agent Eylea®for the treatment of idiopathic polypoidal choroidal vasculopathy, or IPCV, in patients who have not responded to Eylea monotherapy. To date no patients have been enrolled in this clinical trial.

Autosomal Recessive Stargardt Disease (STDG1) • Orphan disease – High unmet medical need – No FDA or EMA approved treatment available • Progressive damage to the macula and retina caused by mutations in the ABCA4 gene • ABCA4 gene makes a protein that normally helps clear away visual cycle byproducts inside retinal cells • Lack of this protein leads to the accumulation of waste and complement activation leading to retinal cell death and loss of vision Sources: The Journal of Biological Chemistry. 2011; 286(21): 18593–18601.

HtrA1 Inhibitor Program: Small Molecules with High Affinity and Specificity for HtrA1 • Strong genetic link between HtrA1 & AMD: – Homozygotes have ~8.2 fold increased risk • AMD patients overexpress HtrA1: – Increased intracellular expression of HtrA1 inside the RPE cells of AMD patients – Increased HtrA1 staining in a majority of drusen of AMD patients’ donor eyes – Increased HtrA1 protein level in aqueous humor of wet AMD patients • Overexpression of HtrA1 protein contributes to AMD: – Damages the extracellular matrix and Bruch’s membrane – Alters and disrupts RPE cells – Upregulates complement – Leads to drusen formation – Interferes with RPE cell function and secondarily impacting photoreceptors Sources: Human Molecular Genetics, 2005: 14, 3227–3236.
