69 observed. The incidence of cataract in the study eye was low (2.3% with Zenkuda versus 1.6% with sham) and in line with expected background rates in patients with DR. About DAYBREAK (and Zenkuda) The Phase 3 DAYBREAK study is a non-inferiority study evaluating parallel investigational arms of Zenkuda and KSI- 501 against active comparator aflibercept. The DAYBREAK study incorporates learnings from prior pivotal trials of Zenkuda and was designed to maximize the probability of meeting the primary endpoint of non-inferiority in visual acuity gains. Patients randomized to Zenkuda will receive individualized dosing every 4 to 24 weeks on an as needed basis following four monthly loading doses. Patients randomized to aflibercept will be dosed per label. The individualized dosing of Zenkuda is determined by a treat-to-dryness proactive approach using the presence of retinal fluid as a disease activity marker, which resembles retina specialists' practice and optimizes each patient's treatment, instead of using a combination of central subfield thickness ("CST") and vision loss. The objectives for Zenkuda in DAYBREAK are to assess its durability potential, strengthen its competitive position in wet AMD and bolster the possible regulatory application package for the program. DAYBREAK was designed to showcase the potential for Zenkuda to be a mainstay biologic for VEGF-driven retinal vascular diseases with both a strong efficacy/immediacy (driven by its enhanced formulation) and a strong durability (driven by its ABC design and science of durability). Topline data for the one-year primary endpoint in DAYBREAK are expected in 3Q 2026. About Zenkuda and BLA Planning Kodiak plans to submit a BLA for Zenkuda supported by the confirmatory GLOW1 and GLOW2 studies in diabetic retinopathy, the BEACON Study in retinal vein occlusion, and the DAYLIGHT Study in wet AMD and intends to work with the FDA on timing of the submission in order to include the ongoing Phase 3 DAYBREAK wet AMD study, if successful, in the BLA. KSI-501 Clinical Program Update KSI-501 is an investigational anti-IL-6, VEGF-trap bispecific therapy built on the ABC platform and is being developed for high prevalence retinal vascular diseases to address the leading 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. 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. Furthermore, higher intraocular levels of IL-6 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. Kodiak has advanced KSI-501 into the Phase 3 study DAYBREAK to evaluate its efficacy and safety in wet AMD. DAYBREAK has completed enrollment. DAYBREAK uses KSI-501's enhanced 50 mg/mL formulation containing both conjugated and unconjugated antibody that is intended to balance immediacy and durability. About DAYBREAK (and KSI-501) The DAYBREAK study is a non-inferiority study evaluating parallel investigational arms of KSI-501 and Zenkuda 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 four monthly loading doses. Patients randomized to aflibercept will be dosed per label. Using the same treat-to-dryness approach as Zenkuda, coupled with fixed intensive proactive dosing, our goal is to maximize both the probability of meeting the primary endpoint as well as the probability of demonstrating additional efficacy benefits. The primary endpoint is non-inferiority in change in visual acuity from baseline to the average of Week 40, 44 and 48. The objective for KSI-501 in DAYBREAK is to explore the efficacy potential of bispecific IL-6 and VEGF inhibition in a broad treatment-naïve wet AMD population. DAYBREAK has completed enrollment. Topline data for the one-year primary endpoint in DAYBREAK are expected in 3Q 2026. KSI-101 Clinical Program Update KSI-101 is a high strength (100 mg/mL) bispecific protein targeting IL-6 and VEGF. We are developing KSI-101 for patients with MESI. MESI is a heterogenous group of diseases that clinically present with macular edema and visual impairment which are caused by a common pathophysiology–inflammation and blood retinal barrier disruption. The clinical presentation of retinal fluid and visual impairment is a mainstay in these patients, irrespective of the location of the inflammation inside of the eye (anterior, intermediate, posterior or all intraocular compartments) or the specific etiology (defined autoimmune associated, idiopathic, post-procedural, or inflammatory choroidal neovascularization).
