Kodiak Sciences Completes Enrollment in GLOW Phase 3 Clinical Trial of Tarcocimab Tedromer (KSI-301) in Patients with Non-Proliferative Diabetic Retinopathy

PALO ALTO, Calif., Aug. 5, 2022 /PRNewswire/ -- Kodiak Sciences Inc. (Nasdaq: KOD), a biopharmaceutical company committed to researching, developing and commercializing transformative therapeutics to treat high prevalence retinal diseases, today announced that it has completed enrollment in its GLOW Phase 3 clinical trial of tarcocimab tedromer (KSI-301), Kodiak's anti-VEGF antibody biopolymer conjugate, in patients with Non-Proliferative Diabetic Retinopathy ("NPDR") without diabetic macular edema ("DME").

"Diabetic retinopathy is the leading cause of vision loss in working-aged Americans and affects up to one third of patients with diabetes. Right now, patients typically wait to begin anti-VEGF treatment until they suffer a sight-threatening complication such as diabetic macular edema or proliferative diabetic retinopathy, partly because currently approved NPDR treatments require frequent eye injections. Not everyone recovers their sight after we treat these complications, so a medicine able to be given at meaningfully longer intervals could help patients and physicians better realize the long-recognized potential of anti-VEGF therapy as a preventive treatment for NPDR," said Charles C. Wykoff, MD, PhD, Director of Research, Retina Consultants of Texas, and a GLOW Study investigator.

"Currently approved medicines need to be injected in the eye every month or every 2 months after 5 monthly initiating doses which limits their utility as a preventive medicine," said Jason Ehrlich, MD, PhD, Kodiak's Chief Medical and Development Officer. "In our GLOW pivotal trial, we are studying tarcocimab tedromer's potential to be dosed just once every 6 months after a reduced density of initiating doses given at baseline, 8 weeks, and 20 weeks into the study. We believe tarcocimab can relieve the high treatment burden for NPDR patients, their family members and physicians and provide an opportunity for real prevention of vision loss among diabetic patients. We are very grateful to the patients and physicians participating in GLOW and the whole Kodiak team for working together to recruit the study well ahead of schedule, and we look forward to the primary results of the study in a year."

About Tarcocimab tedromer (KSI-301)

Tarcocimab tedromer is an investigational anti-VEGF therapy built on Kodiak's Antibody Biopolymer Conjugate (ABC) Platform and is designed to maintain potent and effective drug levels in ocular tissues for longer than existing available agents. Kodiak's objective with tarcocimab tedromer is to develop a new first-line agent to improve outcomes for patients with retinal vascular diseases and to enable earlier treatment and prevention of vision loss for patients with diabetic eye disease. The tarcocimab tedromer clinical program is designed to assess the product's durability, efficacy and safety in wet AMD, DME, RVO and non-proliferative DR (without DME) through clinical studies run in parallel. The Company's GLEAM and GLIMMER pivotal studies in patients with diabetic macular edema, the BEACON pivotal study in patients with retinal vein occlusion, the DAYLIGHT pivotal study in patients with wet AMD, and the GLOW study in patients with NPDR are anticipated to form the basis of the Company's BLA to support potential approval and commercialization in multiple indications. The global tarcocimab tedromer clinical program is being conducted at 150+ study sites in more than 10 countries. Kodiak is developing and owns global rights to tarcocimab tedromer.

About the GLOW Study

The Phase 3 GLOW study is a global, multi-center, randomized pivotal superiority study designed to evaluate the efficacy and safety of tarcocimab tedromer in approximately 240 patients with treatment-naïve, moderately severe to severe non-proliferative diabetic retinopathy (NPDR). Patients are randomized to receive either tarcocimab tedromer every six months after initiating doses given at baseline, 8 weeks and 20 weeks into the study, or to receive sham injections. The primary endpoint is at one year and patients will be treated and followed for two years. Outcomes include changes in diabetic retinopathy severity, measured on a standardized photographic grading scale, and the rate of development of sight-threatening complications due to diabetic retinopathy. We believe tarcocimab tedromer has the potential to be the longest-interval intravitreal therapeutic option for patients with diabetic retinopathy.

Kodiak (Nasdaq: KOD) is a biopharmaceutical company committed to researching, developing and commercializing transformative therapeutics to treat high prevalence retinal diseases. Founded in 2009, 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 antibody-based and chemistry-based therapies and is at the core of Kodiak's discovery engine. Kodiak's lead product candidate, tarcocimab tedromer, is a novel anti-VEGF antibody biopolymer conjugate being developed for the treatment of retinal vascular diseases including wet age-related macular degeneration, the leading cause of blindness in elderly patients in the developed world, and diabetic eye diseases, the leading cause of blindness in working-age patients in the developed world. Kodiak has leveraged its ABC Platform to build a pipeline of product candidates in various stages of development. KSI-501 is our dual inhibitor antibody biopolymer conjugate targeting both VEGF (VEGF-trap) and IL-6 (anti-IL-6 antibody) for the treatment of retinal diseases. We are expanding our early research pipeline to include ABC Platform based triplet inhibitors for multifactorial retinal diseases such as dry AMD and glaucoma. Kodiak is based in Palo Alto, CA.
