Kodiak Sciences Announces Upcoming Presentation of First Time Results of KSI-501ABC Phase 1 Study at the Angiogenesis, Exudation, and Degeneration 2024 Virtual Meeting

January 30, 2024 at 6:30 AM EST

PALO ALTO, Calif., Jan. 30, 2024 /PRNewswire/ -- Kodiak Sciences Inc. (Nasdaq: KOD), a biopharmaceutical company committed to researching, developing and commercializing transformative therapeutics to treat high prevalence retinal diseases, announced today that first time results of the KSI-501ABC Phase 1 Study will be presented at the Angiogenesis, Exudation, and Degeneration 2024 virtual meeting. KSI-501ABC is the second product candidate built on Kodiak's Antibody Biopolymer Conjugate (ABC) Platform.

"We look forward to sharing for the first time the results of our Phase 1 study of KSI-501ABC, our anti-IL-6 antibody and VEGF-trap bispecific therapeutic candidate in its antibody biopolymer conjugate form. The data being presented will outline the safety and bioactivity of KSI-501ABC in patients with diabetic macular edema (DME), a disease known to have high levels of cytokine-mediated microvascular inflammation in addition to VEGF-mediated fluid and leakage. We believe these early results support further clinical development of the KSI-501 program," said Dr. J. Pablo Velazquez-Martin, MD., Senior Vice President of Clinical Research and Development.

Details on the presentation are as follows:

Title: KSI-501 Bispecific Anti-VEGF Anti-IL-6 Antibody Biopolymer Conjugate: First Time Results of the Multiple Ascending Dose Phase 1 Study

Presenter: Mark R. Barakat, M.D., Managing Partner and Director of Clinical Research, Retina Macula Institute of Arizona, Clinical Assistant Professor of Ophthalmology, University of Arizona College of Medicine, Phoenix, AZ

Date and time: Saturday, February 3, 2024, at 3:30 PM ET

Kodiak plans to post the presentation slides on the "Events and Presentations" section of Kodiak's website at at the beginning of the presentation.

About the KSI-501 Clinical Program

KSI-501 is our first-in-class bispecific investigational medicine designed to inhibit both IL-6 mediated inflammation and VEGF-mediated angiogenesis and vascular permeability. IL-6 is known to play an important role in the pathophysiology of multiple retinal diseases and, in conditions for which anti-VEGF therapy is used, elevated levels of ocular IL-6 have been associated with poor anti-VEGF treatment response.

The KSI-501 program will be developed in parallel as a free protein and as a bioconjugate, addressing two very different unmet needs. 

We intend to develop KSI-501 both as (1) KSI-501ABC bioconjugate, for the treatment of high prevalence retinal vascular diseases, where addressing multiple biologies is still a significant unmet need; (2) KSI-501P, its unconjugated bispecific protein, for the treatment of macular edema secondary to inflammation, as currently there are no available intravitreal biologic therapies addressing the spectrum of inflammatory diseases of the retina. 

The Phase 1 study of KSI-501ABC is a multiple ascending dose study in patients with diabetic macular edema (DME). The study enrolled treatment naïve and previously treated DME patients with an 8-week washout period. Each subject received 3 monthly doses and was followed for 24 weeks.

The KSI-501 program may represent a new category of retinal medicine with the potential to provide additional clinical benefits beyond anti-VEGF monotherapies across both high prevalence retinal vascular disease and inflammatory disease of the retina.

About Kodiak Sciences, Inc.

Kodiak (Nasdaq: KOD) is a biopharmaceutical company committed to researching, developing and commercializing transformative therapeutics to treat high-prevalence 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 antibody biopolymer conjugate platform, or ABC Platform, is at the core of Kodiak's discovery engine. Kodiak's first investigational medicine, tarcocimab tedromer, is a novel anti-VEGF antibody biopolymer conjugate explored for the treatment of retinal vascular diseases. Kodiak's second clinical program, KSI-501, built from a first-in-class bispecific protein targeting both IL-6 (anti-IL-6 antibody) and VEGF (VEGF-trap), is intended to treat both retinal inflammatory and high prevalence retinal vascular diseases. Kodiak is based in Palo Alto, CA. For more information, please visit
