5 DAZZLE – Phase 2b/3 Study in Patients with Treatment-Naïve Wet AMD The DAZZLE study was a global, multi-center, randomized pivotal study designed to evaluate the durability, efficacy and safety of tarcocimab in patients with treatment-naïve wet AMD. In February 2022 Kodiak announced that this initial pivotal study did not meet its primary efficacy endpoint of non-inferior visual acuity gains for subjects dosed on extended regimens every 12-, 16- or 20 weeks with tarcocimab compared to subjects given aflibercept every 8 weeks. Following this announcement, Kodiak discontinued the study and concluded remaining trial-associated activities. Antibody Biopolymer Conjugate Drug Substance Manufacturing In August 2020, we entered into a manufacturing agreement with Lonza Ltd (“Lonza”) for the clinical and commercial supply of the Company’s antibody biopolymer conjugate drug substance which included a custom-built manufacturing facility. The manufacturing agreement has an initial term of 8 years, and the Company has the right to extend the term up to a total of 16 years. The Company and Lonza each have the ability to terminate this agreement upon the occurrence of certain events. In April 2021, the agreement was amended to provide for greater manufacturing flexibility, to define a comprehensive mandate as an antibody biopolymer conjugates manufacturing facility to be used for the Company’s antibody biopolymer conjugates pipeline, at clinical as well as commercial scales, across a broad capacity range under the tight quality controls required for ophthalmology and retinal medicines, and to allow for future process and equipment changes as needed. Under the agreement, Kodiak and Lonza planned a custom-built facility (“Ursus”) dedicated to the commercial-scale manufacturing of Kodiak’s drug substance. In January 2023, the custom-built manufacturing suite Ursus was commissioned as a cGMP facility. Kodiak worked together with Lonza and regulatory authorities to obtain approval for Ursus, and we released our first commercial scale cGMP batch of tarcocimab in July 2023. In October 2023, Kodiak made a final payment of $26.8 million to Lonza for final activation of Ursus. Separately, tarcocimab drug product based on our enhanced formulation was released in March 2024 and is being used in the GLOW2 and DAYBREAK pivotal studies. KSI-501 Clinical Program Update KSI-501 is an anti-IL-6, VEGF-trap bispecific antibody biopolymer conjugate built on the ABC Platform and is being developed for high prevalence retinal vascular diseases to address the unmet needs of extended durability and targeting disease biology beyond VEGF for differentiated efficacy. KSI-501 is designed to provide high immediacy/efficacy, driven by the enhanced formulation, and high durability, driven by the ABC Platform and our science of durability. Higher intraocular levels of IL-6 are correlated with poorer BCVA outcomes over time in wet AMD patients treated with anti-VEGF monotherapy, which suggests that IL-6 inhibition in combination with anti-VEGF therapy could lead to improved outcomes. In preclinical models, KSI-501 was shown to be a potent inhibitor of VEGF and IL-6 and, further, was shown to normalize the blood retinal barrier, opening up the possibility that KSI-501 may be a disease-modifying therapy for retinal vascular diseases. A completed Phase 1 multiple ascending dose study demonstrated that repeated monthly dosing of KSI-501 was well tolerated and achieved clinically meaningful and sustained improvement in visual acuity and fluid reduction in patients with diabetic macular edema. Kodiak has advanced KSI-501 into a Phase 3 study DAYBREAK to evaluate its efficacy and safety in wet AMD. The DAYBREAK study is a non-inferiority study evaluating parallel investigational arms of KSI-501 and tarcocimab against active comparator aflibercept. Patients randomized to KSI-501 will receive fixed every 8-week dosing with additional individualized dosing (up to monthly dosing) on an as needed basis after 4 monthly loading doses. Patients randomized to aflibercept will be dosed per its label. The primary endpoint is non-inferiority in change in visual acuity from baseline to the average of Week 40, 44 and 48. DAYBREAK uses KSI-501's enhanced 50 mg/mL formulation containing both conjugated and unconjugated antibody that is intended to deliver high immediacy and high durability. The objective for KSI-501 in DAYBREAK is to explore the efficacy potential of bispecific VEGF and IL-6 inhibition in a broad treatment-naïve wet AMD population. DAYBREAK is now actively enrolling patients.
