PDUFA goal date is August 19, 2023

PARSIPPANY, NJ, USA I February 16, 2023 IIVERIC bio, Inc. (Nasdaq: ISEE) today announced that the U.S. Food and Drug Administration (FDA) has completed its filing review and accepted the company’s New Drug Application (NDA) for avacincaptad pegol (ACP), a novel investigational complement C5 inhibitor for the treatment of geographic atrophy (GA) secondary to Age-Related Macular Degeneration (AMD). The NDA has been granted Priority Review with a Prescription Drug User Fee Act (PDUFA) goal date of August 19, 2023. The company also announced that, at this time, the FDA has not identified any potential review issues and the FDA is not currently planning to hold an Advisory Committee meeting for ACP.

“The FDA’s acceptance of our NDA and Priority Review for avacincaptad pegol bring us another significant step closer to delivering a much-needed treatment to AMD patients living with GA,” said Glenn P. Sblendorio, Chief Executive Officer of Iveric Bio. “We look forward to continuing our collaboration with the FDA throughout the review process.”

The NDA submission is based on the 12-month pre-specified primary efficacy and safety results from the GATHER1 and GATHER2 clinical trials. ACP is the only investigational product for the treatment of GA to achieve the pre-specified 12-month primary endpoint in two phase 3 pivotal trials with observed efficacy rates of up to 35%. In addition, ACP is the first and only investigational therapy to receive Breakthrough Therapy designation for GA secondary to AMD.

“We believe our Special Protocol Assessment for GATHER2, rolling review, Breakthrough Therapy designation and now Priority Review underscore the strength of our GATHER1 and GATHER2 results,” said Pravin U. Dugel, President of Iveric Bio. “We continue to accelerate our commercial launch plans and prepare for a potential approval of ACP for the treatment of GA throughout the AMD disease continuum. This is important because AMD leads to irreversible, and in many cases catastrophic, vision loss.”

About Geographic Atrophy

Age-related macular degeneration (AMD) is the major cause of moderate and severe loss of central vision in aging adults, affecting both eyes in the majority of patients. The macula is a small area in the central portion of the retina responsible for central vision. As AMD progresses, the loss of retinal cells and the underlying blood vessels in the macula results in marked thinning and/or atrophy of retinal tissue. Geographic atrophy, associated with AMD, leads to further irreversible loss of vision in these patients. There are currently no U.S. FDA or European Medicines Agency (EMA) approved treatment options available for patients with geographic atrophy secondary to AMD.

About Avacincaptad Pegol

Avacincaptad pegol (ACP) is an investigational drug that is currently under evaluation for safety and efficacy by the U.S. FDA. ACP is a novel complement C5 protein inhibitor. Overactivity of the complement system and the C5 protein are suspected to play a critical role in the development and growth of scarring and vision loss associated with geographic atrophy (GA) secondary to age-related macular degeneration (AMD). By targeting C5, ACP has the potential to decrease activity of the complement system that causes the degeneration of retinal cells and potentially slow the progression of GA.

About the GATHER Clinical Trials

ACP met its primary endpoint in the completed GATHER1 clinical trial and the ongoing GATHER2 clinical trial both of which are randomized, double-masked, sham-controlled, multicenter Phase 3 clinical trials. These clinical trials evaluated the safety and efficacy of monthly 2 mg intravitreal administration of ACP in patients with GA secondary to AMD. For the first 12 months in both trials, patients were randomized to receive either ACP 2 mg or sham monthly. There were 286 participants enrolled in GATHER1 and 448 participants enrolled in GATHER2. The primary efficacy endpoints in both pivotal studies were based on GA area measured by fundus autofluorescence at three time points: Baseline, Month 6, and Month 12. The mean rate of growth (slope) in GA area from baseline to month 12 using observed data was 35% in GATHER 1 and 18% in GATHER2. In GATHER1 and GATHER2 combined, the most frequently reported treatment emergent adverse events in the 2 mg recommended dose were related to injection procedure. The most common adverse reactions (≥ 5% and greater than sham) reported in patients who received avacincaptad pegol 2 mg were conjunctival hemorrhage (13%), increased IOP (9%), and CNV (7%). After 18 months of treatment in GATHER1 and 12 months of treatment in GATHER2, there were no events of serious intraocular inflammation, vasculitis, or endophthalmitis.

About Priority Review

Priority Review designation means FDA’s goal is to take action on a drug application within six months of application acceptance compared to ten months under Standard Review. Priority Review designation will direct overall attention and resources to the evaluation of applications for drugs that, if approved, would be significant improvements in the safety or effectiveness of the treatment, diagnosis, or prevention of serious conditions when compared to standard applications.1

About FDA Filing Review

The goal of the FDA’s filing review is to determine whether an application, on its face, is sufficiently complete to permit a substantive review. The filing review is only a preliminary evaluation of the NDA and is not indicative of deficiencies that may be identified during the review process.
