75 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. KSI-101 Clinical Program Update KSI-101 is a novel, potent and high strength (100 mg/mL) bispecific protein targeting IL-6 and VEGF. We are developing KSI-101 for patients who have retinal fluid and inflammation. Currently there are no available intravitreal biologic therapies addressing the spectrum of inflammatory conditions of the retina. We believe that retinal inflammatory conditions represent a new market segment separate from the established anti-VEGF market. KSI-101 is a clinical prospect with opportunities and risks uncoupled from the ABC Platform, and as such is an important part of our late-phase portfolio. We have initiated a dose-finding Phase 1b study APEX. The APEX study evaluates KSI-101 in two cohorts, Cohort 1 in patients with diabetic macular edema ("DME") and Cohort 2 in patients with macular edema secondary to inflammation ("MESI"). 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 Phase 2b/3 studies (PEAK and PINNACLE) in MESI. In January 2025, we presented early APEX data in patients with MESI that demonstrated strong treatment response at all KSI-101 dose levels. We expect to present additional APEX data at an Investor R&D update in June 2025. KSI-501 and KSI-101 Manufacturing We have been progressing the manufacturing of KSI-501 and KSI-101 in preparation for the anticipated clinical studies. Clinical material for both KSI-501 (50 mg/mL strength in our enhanced formulation) and KSI-101 (100 mg/mL strength) were successfully manufactured in the first quarter of 2024. ABC Platform Development Kodiak is advancing its platform technology to embed small molecules and other active pharmaceutical ingredients ("API") into Kodiak's proprietary biopolymer backbone to enable high drug-antibody-ratio ("DAR") medicines. The diverse APIs are designed to be released over time to achieve targeted, multi-specific and tailored modulation of biological pathways. The unique combination of high DAR and tailored therapeutic benefit offers potential for broad application to multifactorial systemic and ocular diseases and builds directly from our Antibody Biopolymer Conjugate technology and its 15 years of design, development and manufacturing experience. We call this platform extension our Antibody Biopolymer Conjugate Drug ("ABCD") Platform because we are extending our platform capabilities to include the conjugation of small molecule drugs whereas historically we primarily conjugated biologics such as antibodies. One program is for the treatment of glaucoma, embedding in the biopolymer backbone (i) an NLRP3 small molecule inhibitor, and (ii) a second small molecule that lowers intraocular pressure ("IOP"). The NLRP3 inflammasome is an intracellular complex that drives inflammation and cell death and is known to play a key role in glaucoma progression. The goal of this duet program is to create an intravitreally injected therapy that delivers two mechanisms of action ("MOA") in a sustained release fashion, to fulfill the unmet needs in the glaucoma field for non-topical, long-durability therapy that delivers MOAs beyond IOP lowering and has the potential of quarterly dosing.
