Kodiak Sciences to Present KSI-101 Highlights at 2025 Congress of the International Ocular Inflammation Society

PALO ALTO, Calif.,June 25, 2025/PRNewswire/ -- Kodiak Sciences Inc. (Nasdaq:KOD), a biopharmaceutical company committed to researching, developing and commercializing transformative therapeutics to treat a broad spectrum of retinal diseases, announced today that management along with key opinion leaders will present KSI-101 highlights at the 2025 Congress of the International Ocular Inflammation Society (IOIS) inRio de Janeiro, BrazilonFriday, June 27, 2025.

"We are excited to participate in this year's IOIS meeting and connect with leading experts in ocular inflammation to help advance care for patients with macular edema caused by inflammation," said Pablo Velazquez-Martin, MD, Chief Medical Officer of Kodiak Sciences.

Macular Edema Secondary to Inflammation (MESI) represents a set of serious ocular inflammatory conditions that can cause significant vision loss. Macular edema occurs when inflammation disrupts the blood-retinal barrier, increasing vascular permeability and causing fluid to accumulate in the retina, resulting in macular edema. The inflammation can be triggered by various underlying causes including autoimmune diseases, uveitis or post-surgical inflammation following procedures like cataract surgery. In many cases, the underlying cause of inflammation is not identified. Steroids are commonly used to manage MESI, but they carry the risk of serious, long-lasting ocular side effects, particularly with long-term or high-dose use.

"Inflammation and macular fluid indicate that both interleukin-6 (IL-6) and vascular endothelial growth factor (VEGF) play a synergistic role in driving macular edema and inflammation, but there are no intravitreal biologic therapies that target both underlying disease mechanisms. Managing macular edema secondary to inflammation today is challenging and represents an area of significant need for improvement in today's treatment approach," continued Dr. Velazquez-Martin.

"Together with key opinion leaders, we will share insights into the pathophysiology of macular edema secondary to inflammation, discuss the limitations of current treatment options, highlight real-world case examples of patients and present promising clinical data on KSI-101, a first-in-class, high-strength, bispecific investigational intravitreal biologic designed to target both IL-6 and VEGF simultaneously to meaningfully improve outcomes for patients and reshape the treatment landscape for MESI," concluded Dr. Velazquez-Martin.

The presentation will be available on the "Events and Presentations" section of Kodiak's website athttp://ir.kodiak.com/. Select details are noted below.

KSI-101 is a novel, potent and high strength (100 mg/mL) bispecific protein targeting interleukin-6 (IL-6) and VEGF. We are developing KSI-101 for patients who have macular edema secondary to inflammation (MESI). Currently there are no available intravitreal biologic therapies addressing the spectrum of inflammatory conditions of the retina.

We continue to enroll patients in our dose-finding Phase1bstudy APEX. The goal of the APEX study is to evaluate the safety and tolerability of KSI-101 and to identify two dose levels to progress into dual Phase2b/3 studies (PEAK and PINNACLE) in MESI.

Kodiak Sciences (Nasdaq:KOD) is a precommercial retina focused biotechnology company committed to researching, developing, and commercializing transformative therapeutics to treat a broad spectrum of retinal diseases. We are focused on bringing new science to the design and manufacture of next generation retinal medicines to prevent and treat the leading causes of blindness globally. Our ABC Platform®uses molecular engineering to merge the fields of protein-based and chemistry-based therapies and is at the core of Kodiak's discovery engine. Kodiak's maturing pipeline includes three late-phase clinical assets, all three targeting Phase 3 topline data in 2026.
