Astellas Pharma Inc. (TSE: 4503, President and CEO: Naoki Okamura, "Astellas") and IVERIC Bio, Inc. (NASDAQ:ISEE, CEO: Glenn P. Sblendorio, "Iveric Bio"))) today announced that on April 29, 2023 (Japan time), the Companies have entered into a definitive agreement under which Astellas through Berry Merger Sub, Inc., a wholly-owned subsidiary of Astellas US Holding, Inc., has agreed to acquire 100% of the outstanding shares of Iveric Bio for US$40.00 per share in cash for a total equity value of approximately US$5.9 billion (the "Acquisition"). In the Acquisition, Iveric Bio will become an indirectly wholly-owned subsidiary of Astellas. The total equity value of Iveric Bio in the Acquisition assumes that there are approximately 148.2 million outstanding shares of Iveric Bio common stock on a fully diluted basis. The purchase price represents a premium of 64% to Iveric Bio's unaffected closing share price of US$24.33 on March 31, 2023, and a premium of 75% to Iveric Bio's 30 trading day volume weighted average price as of March 31, 2023. The Boards of Directors of both companies have unanimously approved the transaction.

"We are pleased to reach an agreement with Iveric Bio, a company with exceptional expertise in the R&D of innovative therapeutics in the ophthalmology field," said Naoki Okamura, President and CEO, Astellas. "Iveric Bio has promising programs including Avacincaptad Pegol ("ACP"), an important program for Geographic Atrophy ("GA") secondary to Age-Related Macular Degeneration ("AMD"), and capabilities across the entire value chain in the ophthalmology field. We believe that this acquisition will enable us to deliver greater VALUE to patients with ocular diseases at high risk of blindness."

"This transaction with Astellas, a highly respected pharmaceutical company, demonstrates the significant value that we have built for our stockholders and recognizes the tremendous work by our dedicated team at Iveric Bio," said Glenn P. Sblendorio, Chief Executive Officer of Iveric Bio.

"The opportunity to create a world-class entity with the ophthalmology expertise and capabilities of Iveric Bio and the global reach and resources of Astellas is unique and has the potential to benefit patients worldwide suffering from blinding retinal diseases, including GA," said Pravin U. Dugel, MD, President of Iveric Bio.

1. Strategic Objectives of the Acquisition

Astellas aims to become a cutting-edge, VALUE-driven life science innovator to realize its VISION to be "on the forefront of healthcare change to turn innovative science into VALUE for patients." Through Astellas' R&D strategy, Focus Area Approach, it is working to create innovative drugs for diseases with high unmet medical need by identifying unique combinations of biology and therapeutic modality / technology from multiple perspectives. Currently, Astellas has identified five Primary Focuses, including "Blindness & Regeneration", and is prioritizing investment resources in these areas. As such, this transaction is a key step in building Astellas' product portfolio in this important area.

Iveric Bio focuses on the discovery and development of novel treatments in the field of ophthalmology. The company announced in February 2023 that the U.S. Food and Drug Administration ("FDA") accepted for filing a New Drug Application ("NDA") for ACP for the treatment of GA secondary to AMD. The NDA has been granted priority review with a Prescription Drug User Fee Act ("PDUFA") goal date of August 19, 2023.

ACP, a complement C5 inhibitor, is an investigational drug for GA secondary to AMD and has significant potential to deliver value to a large and underserved patient base. ACP met its primary efficacy endpoint (reduction of the rate of GA progression) with statistical significance across two pivotal clinical trials (GATHER Clinical Trials) and has received breakthrough therapy designation^*1 from the FDA for this indication.

Astellas expects that the acquisition of Iveric Bio will not only contribute to Astellas' FY2025 revenue targets set in its Corporate Strategic Plan 2021, but also, that ACP in conjunction with fezolinetant and PADCEV, is anticipated to be a revenue-generating pillar to help compensate for the decline in sales of XTANDI due to anticipated patent expiration later this decade.

In addition, the acquisition of Iveric Bio will provide a foundation of ophthalmology focused capabilities, including a multi-faceted commercial team, expansive network of experts in the ophthalmology field, established relationships with medical institutions, and the infrastructure and experience to drive our combined ophthalmology business going forward. Furthermore, through acquired capabilities, Astellas will accelerate pre-clinical and clinical development and commercialization activities to positively contribute to the goals of Primary Focus, "Blindness & Regeneration."

Funds for the acquisition consist of newly procured funds from bank loans and issuing of commercial paper totaling approximately 800 billion yen and existing cash on hand. Astellas expects to repay this debt within the next five to seven years. The completion of the Acquisition is not subject to a financing condition. Astellas does not anticipate making any change in its dividend policy following the Acquisition.

The closing of the proposed Acquisition is subject to approval by Iveric Bio's stockholders and other customary closing conditions, including receipt of required regulatory approvals. The companies expect to complete the Acquisition in the second quarter of Astellas' fiscal year 2023 (third calendar quarter of 2023). A copy of the merger agreement regarding the proposed Acquisition will be filed with the U.S. Securities and Exchange Commission ("SEC") and will be publicly available on the SEC's website at (http://www.sec.gov).

About Geographic Atrophy (GA) secondary to Age-related Macular Degeneration (AMD)

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 secondary to AMD, leads to irreversible loss of vision in patients and has a high unmet medical need. It is estimated that approximately 1.6 million people in the U.S. have GA in at least one eye¹.

About Avacincaptad Pegol（ACP）

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 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.
