Item 8.01 Other Events.

On August 8, 2022, Kodiak Sciences Inc. announced that its BEACON Phase 3 study of tarcocimab tedromer (KSI-301; tarcocimab), its novel antibody biopolymer conjugate, met the primary endpoint of non-inferior change from baseline in visual acuity at week 24 compared to aflibercept in patients with macular edema due to retinal vein occlusion. Tarcocimab also demonstrated robust anatomic responses and a favorable safety profile. After two initial monthly loading doses, tarcocimab was dosed every two months compared to consistent monthly dosing for aflibercept.

The BEACON study is a randomized, double-masked, multicenter, active comparator-controlled Phase 3 clinical trial in treatment naïve patients with vision loss and macular edema due to retinal vein occlusion, including both branch (BRVO) and central (CRVO) subtypes. This condition occurs when a branch or central draining vein of the retina becomes blocked, for example due to chronic hypertension, and the retina becomes swollen as a result. The study randomized 568 participants (438 BRVO, 130 CRVO) from 11 countries 1:1 into two treatment arms: tarcocimab tedromer 5 mg on a fixed every-8-week dosing regimen following 2 monthly loading doses and aflibercept 2 mg on a fixed every 4-week dosing regimen per its label.

The primary efficacy endpoint of the study was change in best-corrected visual acuity (BCVA) score, a measure of the best vision a person can achieve when reading letters on an eye chart, from baseline at week 24. In the first 24 weeks of the study, patients randomized to tarcocimab received a total of 4 doses compared with 6 doses received by patients randomized to aflibercept.

The non-inferiority margin for the comparison to aflibercept at week 24 was established at 4.5 eye chart letters based on pretrial regulatory feedback and precedent. Under the study’s prespecified statistical analysis plan and hierarchical testing strategy for control of type 1 error, non-inferiority of tarcocimab to aflibercept was first demonstrated in patients with branch RVO, with a statistically significant p-value of 0.0004, and then also demonstrated with a statistically significant p-value of 0.0243 in the overall RVO population (branch and central types combined). Tarcocimab tedromer was safe and well tolerated in the study, with no new safety signals identified. A low rate of intraocular inflammation was observed in both groups (1.4% vs 0.4% for tarcocimab and aflibercept, respectively) with no vasculitis or retinal arterial occlusion events reported in any patient.

Full primary results from the BEACON study are expected to be presented by BEACON Study Investigators at upcoming ophthalmology congresses in September 2022.
