Description of Business and Organization

IVERIC bio, Inc. (the “Company”) is a science-driven biopharmaceutical company focused on the discovery and development of novel treatments for retinal diseases with significant unmet medical needs. The Company is committed to having a positive impact on patients’ lives by delivering high-quality, safe and effective treatments designed to address debilitating retinal diseases, including earlier stages of age-related macular degeneration (“AMD”).

The Company’s lead asset is its clinical stage product candidate avacincaptad pegol (also referred to as Zimura®), a complement C5 inhibitor. It is currently targeting the following diseases with avacincaptad pegol:

•Geographic Atrophy (“GA”), which is the advanced stage of AMD, and is characterized by marked thinning or atrophy of retinal tissue, leading to irreversible loss of vision;

•intermediate AMD, which is an earlier stage of AMD that precedes GA; and

•autosomal recessive Stargardt disease (“STGD1”), which is an orphan inherited condition characterized by progressive damage to the central portion of the retina (the “macula”) and other retinal tissue, leading to loss of vision.

In October 2019, the Company announced positive 12-month data for GATHER1, its first Phase 3 clinical trial evaluating avacincaptad pegol for the treatment of GA secondary to AMD. In GATHER1, 286 patients were randomized to receive various doses of avacincaptad pegol, including avacincaptad pegol 2 mg, or sham control. The Company observed a 27.7% (p-value = 0.0063) reduction in the mean rate of growth (slope) estimated based on GA area between the avacincaptad pegol 2 mg group and the corresponding sham control group over 12 months, when performing the primary analysis, and a 35.4% (p-value = 0.0050) reduction in the mean rate of growth (slope) estimated based on GA area between the two groups over 12 months, when performing the supportive analysis. These results are based on a post-hoc analysis of the GATHER1 data using the U.S. Food and Drug Administration (“FDA”) preferred primary efficacy endpoint analysis from the Company’s Special Protocol Assessment (“SPA”), which is described further below. The Company analyzed the endpoint by using the square root transformation of the GA area, which it refers to as the primary analysis, and the Company analyzed the endpoint by using the observed GA area (without square root transformation), which it refers to as the supportive analysis. In GATHER1, through month 12, the Company did not observe any events of endophthalmitis or ischemic optic neuropathy events, and only one case of intraocular inflammation, which was mild and transient and reported as related to the injection procedure. The incidence of choroidal neovascularization (“CNV”) in the study eye through month 12 was 6 patients (9.0%) in the avacincaptad pegol 2 mg group and 3 patients (2.7%) in the corresponding sham control group.

In June 2020, the Company started enrolling patients in GATHER2, its second Phase 3 clinical trial evaluating avacincaptad pegol for the treatment of GA secondary to AMD. In July 2021, the Company received a written agreement from the FDA under the SPA for the overall design of GATHER2. The SPA is a procedure by which the FDA provides a clinical trial sponsor with an official evaluation and written guidance on the design of a proposed protocol intended to form the basis for a new drug application (“NDA”). In connection with our SPA, the FDA recommended, and the Company accepted, modifying the primary efficacy endpoint for the GATHER2 trial from the mean rate of change in GA area over 12 months measured by fundus autofluorescence (“FAF”) at three timepoints: baseline, month 6 and month 12, to the mean rate of growth (slope) estimated based on GA area measured by FAF in at least three timepoints: baseline, month 6 and month 12.

In September 2022, the Company announced positive 12-month top-line data for GATHER2. In GATHER2, 448 patients were randomized on a 1:1 basis to receive avacincaptad pegol 2 mg or sham control over the first 12 months of the trial. At 12 months, the Company measured the primary efficacy endpoint in accordance with the SPA. In GATHER2, the Company observed a 14.3% (p-value = 0.0064) reduction in the mean rate of growth (slope) in GA area between the two groups at 12 months with the primary analysis, and a 17.7% (p-value = 0.0039) reduction in the mean rate of growth (slope) in GA area between the two groups at 12 months with the supportive analysis. The Company did not observe any events of endophthalmitis, intraocular inflammation events, events of vasculitis or ischemic optic neuropathy events through month 12, and the incidence of choroidal neovascularization (“CNV”) in the study eye through month 12 was 15 patients (6.7%) in the avacincaptad pegol 2 mg group and 9 patients (4.1%) in the sham control group.

The Company believes that with the statistically significant results from its GATHER1 and GATHER2 trials and the safety profile of avacincaptad pegol to date, it has sufficient data from two independent, adequate and well-controlled pivotal clinical trials of avacincaptad pegol in GA secondary to AMD to support an application for marketing approval. The Company

recently submitted to the FDA the first part of its NDA, which includes the complete clinical data package for avacincaptad pegol, for rolling review of avacincaptad pegol for the treatment of GA secondary to AMD. The Company plans to complete the submission of the NDA to the FDA by the end of 2022.

In addition to avacincaptad pegol, the Company is developing its preclinical product candidate IC-500, a High temperature requirement A serine peptidase 1 protein (“HtrA1”) inhibitor, for GA secondary to AMD and potentially other age-related retinal diseases.

The Company’s portfolio also includes two preclinical stage gene therapy product candidates (IC-100 and IC-200)

and several ongoing gene therapy research programs, each of which uses adeno-associated virus (“AAV”) for gene delivery. These AAV mediated gene therapy programs are targeting the following orphan inherited retinal diseases (“IRDs”):

•rhodopsin-mediated autosomal dominant retinitis pigmentosa (“RHO-adRP”), which is characterized by progressive and severe bilateral loss of vision leading to blindness;

•IRDs associated with mutations in the BEST1 gene, including Best vitelliform macular dystrophy (“Best disease”);

•Leber Congenital Amaurosis type 10 (“LCA10”), which is characterized by severe bilateral loss of vision at or soon after birth;

•STGD1; and

•IRDs associated with mutations in the USH2A gene, which include Usher syndrome type 2A, and USH2A-associated non-syndromic autosomal recessive retinitis pigmentosa.

As the Company focuses its efforts on and prioritizes the development and potential commercialization of avacincaptad pegol, it has been considering its development options for IC-100 and IC-200, which the Company has been developing for RHO-adRP and BEST1-related IRDs, respectively. It is currently seeking a collaborator or licensee for the future development and potential commercialization of these product candidates.
