About Zenkuda™ (tarcocimab tedromer)

Zenkuda is an investigational anti-VEGF therapy built on Kodiak’s proprietary Antibody Biopolymer Conjugate (ABC) Platform. Zenkuda has a mean ocular half-life in humans of 20 days, approximately three times longer than approved anti-VEGF therapies, and is designed to maintain effective drug levels in ocular tissues for longer. Zenkuda is being developed as a mainstay intravitreal biologic monotherapy that provides high immediacy, driven by the enhanced formulation, and high durability, driven by the ABC® platform and our science of durability, with the ultimate objective of providing, once approved, a flexible 1-month through 6-month label for all patients with retinal vascular disease (treatment-naïve, treatment-experienced, mild patients, and severe patients).

Zenkuda has completed four successful Phase 3 pivotal studies: the Phase 3 GLOW1 and GLOW2 studies in diabetic retinopathy (DR), the Phase 3 BEACON study in retinal vein occlusion (RVO), and the Phase 3 DAYLIGHT study in wet AMD. In the GLOW1 and GLOW2 studies, Zenkuda successfully treated DR patients and prevented disease progression with 100% of patients on extended 6-month dosing at Year 1. In the BEACON study, during the first 6 months, Zenkuda-treated patients were dosed at 8-week intervals (as opposed to 4-week intervals for aflibercept). In the second 6 months, identical retreatment criteria were used for the Zenkuda and aflibercept arms, and nearly half of Zenkuda patients did not require any treatment while achieving similar vision and anatomical outcomes as the aflibercept group at one year. In the DAYLIGHT study, Zenkuda demonstrated non-inferior efficacy results and compelling safety and tolerability at a once-monthly dosing interval. Zenkuda is currently being studied in the Phase 3 DAYBREAK study in wet AMD, the final anticipated Phase 3 study in the program. In DAYBREAK, patients are treated on an every 1-month through every 6-month treatment interval, depending on an AI-driven assessment of disease activity. Topline results for the DAYBREAK one-year primary endpoint are expected in September 2026.

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 and vision loss. Specific objectives for Zenkuda in DAYBREAK are (1) to assess safety, (2) to meet the primary endpoint of non-inferiority of best corrected visual acuity, (3) to explore the strength of fluid control through the loading phase, and (4) to demonstrate a differentiated durability profile. General objectives for Zenkuda in DAYBREAK are to 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 September 2026.

About KSI-501

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.

Kodiak has advanced KSI-501 into the registrational Phase 3 study DAYBREAK to evaluate its efficacy and safety in wet AMD. DAYBREAK uses KSI-501’s enhanced 50 mg/mL formulation containing both conjugated and unconjugated antibody that is intended to balance immediacy and durability. DAYBREAK has completed enrollment. Topline data for the one-year primary endpoint in DAYBREAK are expected in September 2026.

Kodiak has also advanced KSI-501 into the registrational Phase 3 ALTO study designed to demonstrate the superiority of bispecific KSI-501 (anti-VEGF, anti-IL-6) versus monospecific aflibercept (anti-VEGF) in patients with diabetic macular edema. The ALTO study is now enrolling patients.

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 September 2026. Additional information about DAYBREAK can be found on www.clinicaltrials.gov under Trial Identifier NCT06556368 (https://clinicaltrials.gov/study/NCT06556368).

About ALTO

The ALTO Study is a global, multicenter, randomized, double-masked, active comparator-controlled Phase 3 study evaluating the efficacy and safety of intravitreal KSI-501 5 mg compared with intravitreal aflibercept 2 mg in patients with visual impairment secondary to center-involved DME. Approximately 910 patients, treatment-naïve or previously treated, will be randomized 5:3:5 to one of three arms: (A) KSI-501 5 mg every 8 weeks, with monthly assessment for additional individualized dosing, following six monthly loading doses; (B) KSI-501 5 mg on an individualized regimen of every 4 to 24 weeks, following six monthly loading doses; and (C) aflibercept 2 mg every 8 weeks, following five monthly loading doses.

The primary endpoint is the mean change in best-corrected visual acuity (BCVA) from baseline to the average of Week 48 and Week 52. The key secondary endpoint is the proportion of patients improving two or more steps on the DRSS from baseline at Week 48. Additional secondary and exploratory endpoints evaluate visual function, retinal anatomy, treatment burden and durability, and safety. Participants will be treated and followed for approximately 96 weeks.

About KSI-101

KSI-101 is a novel, potent and high strength (100 mg/mL) bispecific protein targeting IL-6 and VEGF for the treatment of MESI. Data from our dose-finding Phase 1b APEX study demonstrated robust anatomical and visual responses across MESI patients. More than half of patients achieved ≥15-letter gains in best corrected visual acuity, with additional benefit at higher dose levels. Rapid vision improvements and anatomical response were observed with 10-letter gains by Week 4 in top dose groups and OCT CST <325 microns achieved as early as Week 1 in top dose groups. Continued anatomical improvement was observed over time with >90% resolution of intraretinal (IRF) and subretinal fluid (SRF) by Week 8 and 20/25 Snellen visual acuity by Week 20. In top dose groups, ≥90% achieved complete absence of IRF and SRF, indicating retinal dryness and normalization of retinal architecture. KSI-101 also continued to be well tolerated with a favorable safety profile. The top two dose levels in APEX have been advanced into the Phase 3 pivotal studies, PEAK and PINNACLE. The PEAK and PINNACLE studies are actively enrolling.

About PEAK and PINNACLE

The PEAK and PINNACLE studies are superiority studies evaluating two dose levels of KSI-101 (5 mg and 10 mg) compared to sham treatment in patients with MESI. PEAK and PINNACLE are identical in study design with key differences in patient population. PEAK includes patients with more severe disease (moderate to severe macular edema and vision impairment) and PINNACLE includes patients with milder disease (mild macular edema and any vision impairment), as well as patients with moderate to severe macular edema with good vision. Together, PEAK and PINNACLE are designed to enroll complementary patient populations and to cover a wide spectrum of MESI patients.

Patients randomized to the KSI-101 treatment arms will receive fixed monthly dosing for 6 doses (from Day 1 to Week 20), with subsequent individualized dosing (up to monthly dosing) for 6 additional visits (Week 24 to Week 44). Patients in the sham arm will receive monthly sham dosing for 6 doses followed by sham PRN. The primary and key secondary endpoints will be evaluated at Week 24. PEAK and PINNACLE are now actively enrolling patients. Topline data readouts for Pivotal Analysis 1 (PEAK patients 1 – 300) and Pivotal Analysis 2 (PEAK patients 301 – 600 and PINNACLE patients 1 – 300) are expected in December 2026 and 2Q 2027, respectively.
